To find the value of r in the equation 690 = (200*(1-(1+r)^12)/r) + (1000/(1+r)^12), we need to solve the equation for r.
In order to solve this equation algebraically, we can start by simplifying it. First, let's simplify the expression (1-(1+r)^12)/r by multiplying both the numerator and denominator by (1+r)^12 to eliminate the fraction. This yields (1+r)^12 - 1 = r.
Now, we can rewrite the equation as 690 = 200*((1+r)^12 - 1)/r + 1000/(1+r)^12.
To further simplify the equation, we can multiply both sides by r to eliminate the fraction. This gives us 690r = 200*((1+r)^12 - 1) + 1000.
Expanding (1+r)^12 - 1 using the binomial theorem, we can simplify the equation further and solve for r using numerical methods or a graphing calculator.

1. Given[e'dA,where R is the region enclosed by x=yand x=-y+2 (a) (b) Sketch the region, R Set up the iterated integrals. Hence, evaluate the double integral using the suitable orders of integration. [10 marks]
To sketch the region, R enclosed by x=y and x=-y+2, we need to find the points of intersection of the two lines.
That is, we equate x=y and x=-y+2x = y and x = -y + 2
Since they are both equal to x, we set them equal to each other: y = -y + 2.
Solving for y:y = 1Therefore, x = 1
Hence, the points of intersection are (1, 1) and (-1, -1). The lines intersect at the origin.
Therefore, the required region is a diamond-shaped region with sides of length 2, as shown below:
sketch of the region, R
Part (b)To set up the iterated integrals, we consider the horizontal strips and vertical strips of the region, R.
The horizontal strips are bounded below by x=y and above by x=-y+2. We can see that the lower bound is y=x and the upper bound is y=-x+2.
Hence, the iterated integral in the form of dydx is:
∫(∫e^(xdA)dy)dx=∫(-x+2)^x e^xdx ... (1)
The vertical strips are bounded on the left by x=y and on the right by x=-y+2.
We can see that the left bound is x=y and the right bound is x=2-y. Hence, the iterated integral in the form of dxdy is:
∫(∫e^(xdA)dx)dy=∫(y^2-2y+2)^y e^ydy ... (2)
To evaluate the double integral using the suitable orders of integration, we can use either equation (1) or (2).
Since (2) involves more complicated integration, we will use equation (1):
∫(-1)^1 (∫(-x+2)^x e^xdx)dx.
=∫(-1)^1 e^x((x-1)-1)dx.
=∫(-1)^1 e^x(x-2)dx.
=e^x(x-3)|_-1^1.
=(e-1)(1-3).
=2-e.
Therefore, the value of the double integral is 2-e.

• problem 2: suppose the joint probability density of x and y is fx,y (x, y) = 3y 2 with 0 ≤ x ≤ 1 and 0 ≤ y ≤ 1 and zero everywhere else. 1. compute e[x|y = y]. 2. compute e[x3 x|x < .5]
The expected value of X given Y = y is 0.5, and the expected value of X^3 given X < 0.5 is 0.03125.
To compute the given expectations, we need to use the concept of conditional expectations.
To compute E[X | Y = y], we need to find the conditional probability density function f(x | y) and calculate the expectation using the conditional density.
The conditional probability density function can be found using the formula:
f(x | y) = f(x, y) / fY(y)
where fY(y) is the marginal probability density function of Y.
In this case, since f(x, y) = 3y^2 and the support of X and Y is 0 ≤ x ≤ 1 and 0 ≤ y ≤ 1, we have:
fY(y) = ∫[0,1] f(x, y) dx = ∫[0,1] 3y^2 dx = 3y^2 * x |[0,1] = 3y^2
Therefore, the conditional probability density function is:
f(x | y) = (3y^2) / (3y^2) = 1
Since the conditional probability density function is constant, the conditional expectation E[X | Y = y] is simply the midpoint of the support of X, which is (0 + 1) / 2 = 0.5.
To compute E[X^3 | X < 0.5], we need to find the conditional probability density function f(x | X < 0.5) and calculate the expectation using the conditional density.
The conditional probability density function can be found using the formula:
f(x | X < 0.5) = f(x) / P(X < 0.5)
where f(x) is the marginal probability density function of X and P(X < 0.5) is the cumulative distribution function of X evaluated at 0.5.
The marginal probability density function of X is:
fX(x) = ∫[0,1] f(x, y) dy = ∫[0,1] 3y^2 dy = y^3 |[0,1] = 1
Therefore, the conditional probability density function is:
f(x | X < 0.5) = f(x) / P(X < 0.5) = 1 / P(X < 0.5)
To find P(X < 0.5), we integrate the marginal probability density function of X from 0 to 0.5:
P(X < 0.5) = ∫[0,0.5] fX(x) dx = ∫[0,0.5] 1 dx = x |[0,0.5] = 0.5
Therefore, the conditional probability density function is:
f(x | X < 0.5) = 1 / P(X < 0.5) = 1 / 0.5 = 2
Now we can calculate the conditional expectation:
E[X^3 | X < 0.5] = ∫[0,0.5] x^3 * f(x | X < 0.5) dx = ∫[0,0.5] x^3 * 2 dx = 2 * (1/4) * x^4 |[0,0.5] = 2 * (1/4) * (0.5^4 - 0^4) = 2 * (1/4) * (0.0625) = 0.03125
Therefore, E[X^3 | X < 0.5] = 0.03125.

Solve Applications Modeled by Quadratic Equations. A bullet is fired straight up from a BB gun with initial velocity 1320 feet per second at an initial height of 8 feet. Use the formula h = 16t² + vot + 8 to determine how many seconds it will take for the bullet to hit the ground. (That is, when will h = 0?). Round your answer to one decimal place. - The bullet will hit the ground after seconds. Question Help: Video Message instructor Submit Question
A quadratic equation is a second-degree polynomial equation in one variable, typically written in the form:ax^2 + bx + c = 0, where "x" represents the variable, and "a", "b", and "c" are constants. The coefficient "a" must not be equal to zero.
Finding the value of t at the height (h) of zero is necessary to calculate how long it takes the bullet to impact the ground. We can employ the following formula:
h = 16t² + vot + 8
Using h = 0 and vo = 1320 as substitutes, get t.
0 = 16t² + 1320t + 8
At2 + bt + c = 0 is a quadratic equation, where a = 16, b = 1320, and c = 8.
Using the quadratic formula, we can solve this quadratic equation:
T is equal to (-b (b2 - 4ac)) / (2a).
Inputting different values for a, b, and c:
t = (-(1320) ± √((1320)² - 4(16)(8))) / (2(16))
Simplifying:
t = (-1320 ± √(1742400 - 512)) / 32
t = (-1320 ± √(1741888)) / 32
t = (-1320 ± 1319.91) / 32
Now, we can calculate two possible values of t:
t₁ = (-1320 + 1319.91) / 32 ≈ 0.03 seconds (approximated to two decimal places)
t₂ = (-1320 - 1319.91) / 32 ≈ -41.3 seconds (approximated to one decimal place).
Since time cannot be negative in this context, we disregard the negative value. Therefore, it will take approximately 0.03 seconds (rounded to one decimal place) for the bullet to hit the ground.

Draw all non-isomorphic trees with 6 verticies wher the maximal degree of a vertex is 3. Explain why there are no other trees of this type
There are two non-isomorphic trees with 6 vertices where the maximal degree of a vertex is 3.
The first tree is a chain-like structure with 6 vertices connected in a linear fashion. Each vertex has a degree of 1 except for the two endpoints, which have a degree of 2.
The second tree is a star-like structure with a central vertex connected to 5 peripheral vertices. The central vertex has a degree of 5, while the peripheral vertices have a degree of 1.
There are no other trees of this type with 6 vertices and a maximal degree of 3 because of the constraints on the maximum degree.
Since the maximal degree is 3, a vertex cannot have more than 3 edges incident to it. With 6 vertices, the maximum number of edges in a tree would be 5 (assuming no isolated vertices).
The chain-like structure and the star-like structure are the only possibilities that satisfy these conditions.

An algo- rithm that uses more, but still linear number, say cn, of comparisons, for some small constant c, can still attract some but appropriately fewer marks
The algorithm uses at most 3n/2 comparisons.
To design an algorithm that finds the minimum and maximum of n numbers using at most 3n/2 comparisons, we can employ a technique known as "tournament method" or "pairwise comparison."
Here's the algorithm:
Initialize two variables, min and max, with the first number from the table.
Set the index i = 2.
While i ≤ n, do the following:
a. Compare the (i-1)th and ith numbers from the table.
b. If the (i-1)th number is smaller than the ith number:
Compare the (i-1)th number with min.
Compare the ith number with max.
c. If the (i-1)th number is greater than the ith number:
Compare the ith number with min.
Compare the (i-1)th number with max.
d. Increment i by 2.
If n is odd, compare the last number with both min and max.
Return min and max as the minimum and maximum of the given table.
To analyze the number of comparisons, let's consider the worst-case scenario. In the worst case, the numbers in the table are sorted in descending order.
In each iteration of the while loop, we compare two numbers, which makes 1 comparison. Since the loop iterates n/2 times, the total number of comparisons within the loop is n/2.
If n is odd, we perform two additional comparisons to compare the last number with both min and max.
Therefore, the total number of comparisons in the worst case is (n/2) + 2.
Using mathematical inequality, we can show that (n/2) + 2 ≤ 3n/2.
(n/2) + 2 ≤ 3n/2
(n + 4) ≤ 3n
4 ≤ 2n
2 ≤ n
Since the given condition states that n is at least 2, the inequality holds true for all valid values of n.
Hence, the algorithm uses at most 3n/2 comparisons.

Bx2 + 2 for 2 ≤x < 3
2Ax + B for x ≥3
A common formula for locating the answers to quadratic equations is the quadratic formula. The quadratic equation's solution values for "x" are given by this formula.
The discriminant, or term inside the square root, is b2 - 4ac, and it specifies the type of solutions:
Checking if the function is continuous at the points where the various parts of the function meet is necessary to confirm that the function f(x) is continuous on the interval (-, ).
The first part of the function switches to the second part at x = 2. At x = 2, the left-hand limit and the right-hand limit must be equal for the function to be continuous.
Using the left-hand limit, the equation is as follows: lim(x2-) f(x) = lim(x2-) (A(-x) + 6 - 1) = A(-2) + 6 - 1 = A2 + 5
Using the right-hand restriction:
B(22) + 2 = B(x2 + 2) + 2 = 4B + 2 = lim(x2+) f(x) = lim(x2+) (Bx2 + 2)
A2 + 5 must equal 4B + 2 for the function to be continuous at x = 2.
A√2 + 5 = 4B + 2
Then, at x = 3, where the second piece changes into the third piece, we examine the continuity. Once more, the limits on the left and right hands must be equal.
Using the left-hand limit as an example, the formula is lim(x3-) f(x) = lim(x3-) (Bx2 + 2) = B(32) + 2 = 9B + 2.
Using the right-hand limit, the equation is as follows: lim(x3+) f(x) = lim(x3+) (2Ax + B) = 2A(3) + B = 6A + B
9B + 2 must equal 6A + B in order for the function to be continuous at x = 3.
9B + 2 = 6A + B
There are now two equations:
A√2 + 5 = 4B + 2 9B + 2 = 6A + B
We can get the values of A and B that allow the function to be continuous on (-, ) by simultaneously solving these equations.

How to find the power series?To find a power series representation for the function f(x) = arctan(x/8), we can use the Maclaurin series expansion of the arctan function.
The Maclaurin series expansion for arctan(x) is given by:
arctan(x) = x - (x³)/3 + (x⁵)/5 - (x⁷)/7 + ...
Substituting x/8 for x, we have:
arctan(x/8) = (x/8) - ((x/8)³)/3 + ((x/8)⁵)/5 - ((x/8)⁷)/7 + ...

Prove that in any bi-right quadrilateral CABDC, LC > Dif and only BD > AC. (Assume LA and B are the two right angles.)
in any bicentric quadrilateral CABDC, LC > Dif if and only if BD > AC.
To prove that in any bicentric quadrilateral CABDC (with LA and B as the right angles), we have LC > Dif if and only if BD > AC, we can use the Pythagorean theorem and some geometric properties.
First, let's assume that LC > Dif.
From the properties of a bicentric quadrilateral, we know that the diagonals AC and BD are perpendicular and intersect at point L (the intersection of the diagonals is denoted as L).
Now, consider the right triangle ALC. By the Pythagorean theorem, we have:
AL² + LC² = AC²
Since LC > Dif, we can rewrite this inequality as:
AL² + Dif² + (LC - Dif)² = AC² (1)
Next, consider the right triangle BLC. Again, by the Pythagorean theorem, we have:
BL² + LC² = BD²
Since LC > Dif, we can rewrite this inequality as:
(BD - Dif)² + Dif² + LC² = BD² (2)
Now, let's compare equations (1) and (2):
AL² + Dif² + (LC - Dif)² = AC²
(BD - Dif)² + Dif² + LC² = BD²
Expanding the squares and rearranging the terms, we get:
AL² + LC² - 2(LC)(Dif) + Dif² = AC²
BD² - 2(BD)(Dif) + Dif² + LC² = BD²
Simplifying the equations, we find:
LC² - 2(LC)(Dif) + Dif² = AC²
- 2(BD)(Dif) + Dif² + LC² = 0
Now, notice that the second equation simplifies to:
- 2(BD)(Dif) + Dif² + LC² = 0
- 2(BD)(Dif) = Dif² - LC²
2(BD)(Dif) = (Dif + LC)(Dif - LC)
Since BD, Dif, and LC are all positive lengths, we can conclude that:
BD > AC if and only if Dif + LC > Dif - LC
BD > AC if and only if 2LC > 0
Since 2LC is always greater than zero, we can conclude that BD > AC if and only if LC > Dif.

Given f(x) = e for 0≤x≤oo, the P(X < 1) is:
(a) 0.632
(b) 0.693
(c) 0.707
(d) 0.841
Given f(x) = e for 0≤x≤ [infinity]o, the median of X is:
The value of P(X < 1) is:(c) 0.707.The median of X is:(d) Not defined (infinite)
For a continuous random variable X with a probability density function (pdf) f(x), the probability of X being less than a specific value, denoted P(X < x), can be calculated by integrating the pdf from negative infinity to x:
P(X < x) = ∫[negative infinity to x] f(t) dt
In this case, the pdf is given as f(x) = e for 0 ≤ x ≤ infinity.
To find P(X < 1), we integrate the pdf from negative infinity to 1:
P(X < 1) = ∫[negative infinity to 1] e dx
Integrating the constant e gives:
P(X < 1) = [e] evaluated from negative infinity to 1
= e - 0
= e
Therefore, P(X < 1) is equal to e.
Approximately, e is approximately equal to 2.71828. Rounding this value to three decimal places gives:
P(X < 1) ≈ 0.718
Among the given answer choices, the closest value to 0.718 is:
(c) 0.707
Regarding the median, for a continuous random variable, the median is the value of x for which P(X < x) = 0.5. However, in this case, the pdf f(x) = e does not reach 0.5 for any finite value of x. As x approaches infinity, the pdf approaches infinity as well. Therefore, the median of X is not defined (infinite).
The value of P(X < 1) is approximately 0.718, which is closest to option (c) 0.707. The median of X is not defined (infinite).

Let y = 2√x.
Find the differential dy= _______dx.
Find the change in y, Δy when x = 4 and Δx = 0.2 _________
Find the differential dy when x = 4 and dx = 0.2 __________
To find the differential dy, we differentiate y = 2√x with respect to x.
dy/dx = d/dx (2√x)
To differentiate √x, we can use the power rule:
d/dx (√x) = (1/2) * x^(-1/2)
Applying the constant multiple rules, we have:
dy/dx = (1/2) * 2 * x^(-1/2) = x^(-1/2)
Therefore, the differential dy is given by:
dy = x^(-1/2) * dx
Now, let's find the change in y, Δy when x = 4 and Δx = 0.2.
Δy = dy = x^(-1/2) * dx
Substituting x = 4 and Δx = 0.2, we have:
Δy = 4^(-1/2) * 0.2 = (1/2) * 0.2 = 0.1
Therefore, the change in y, Δy, when x = 4 and Δx = 0.2 is 0.1.
Lastly, let's find the differential dy when x = 4 and dx = 0.2.
dy = x^(-1/2) * dx
Substituting x = 4 and dx = 0.2, we have:
dy = 4^(-1/2) * 0.2 = (1/2) * 0.2 = 0.1

To find the integral of a function, we can use the power rule and the properties of integration. In this case, we have the function (7[tex]x^{2}[/tex] + 5[tex]x^{7}[/tex]) and we want to evaluate the integral with respect to x from 3 to -1.
Using the power rule, we integrate each term separately. The integral of 7[tex]x^{2}[/tex] is (7/3)[tex]x^{3}[/tex], and the integral of 5[tex]x^{7}[/tex] is (5/8)[tex]x^{8}[/tex].
Next, we apply the limits of integration. Evaluating the antiderivative at the upper limit (3) gives us [(7/3)([tex]3^{3}[/tex]) + (5/8)([tex]3^{8}[/tex])]. Similarly, evaluating the antiderivative at the lower limit (-1) gives us [(7/3)([tex](-1)^{3}[/tex]) + (5/8)([tex](-1)^{8}[/tex])].

How many possible outcomes contain exactly three heads if the coin is flipped 11 times?
How many possible outcomes contain at least three heads if the coin is flipped 11 times?
How many possible outcomes contain the same number of heads and tails if the coin is flipped 8 times?
There are 8 + 28 + 1 = 37 possible outcomes that contain the same number of heads and tails if the coin is flipped 8 times.
A coin is flipped, and each flip comes up as either heads or tails.
There are two possible outcomes of a coin flip: heads or tails.
The possible number of outcomes in a given number of coin flips can be calculated using the formula 2^n, where n is the number of coin flips.
Now, let's solve the questions one by one:1.
How many possible outcomes contain exactly three heads if the coin is flipped 11 times?
In this case, we need to find the possible number of outcomes that contain exactly 3 heads in 11 coin flips.
We can use the binomial distribution formula to calculate this.
The formula is given by: P(X = k) = (n choose k) * p^k * (1 - p)^(n - k)where n is the number of coin flips, k is the number of heads we want to find, p is the probability of heads (1/2), and (n choose k) is the number of ways we can choose k heads from n coin flips.
So, we have:P(X = 3) = (11 choose 3) * (1/2)^3 * (1/2)^(11 - 3)= 165 * (1/2)^11= 165/2048
Therefore, there are 165 possible outcomes that contain exactly three heads if the coin is flipped 11 times.2.
How many possible outcomes contain at least three heads if the coin is flipped 11 times?
In this case, we need to find the possible number of outcomes that contain at least three heads in 11 coin flips.
We can use the binomial distribution formula to calculate this.
The formula is given by:P(X ≥ k) = Σ (n choose i) * p^i * (1 - p)^(n - i)
where Σ is the sum of all the terms from k to n, n is the number of coin flips, k is the minimum number of heads we want to find, p is the probability of heads (1/2), (n choose i) is the number of ways we can choose i heads from n coin flips.
So, we have P(X ≥ 3) = Σ (11 choose i) * (1/2)^i * (1/2)^(11 - i)where i = 3, 4, 5, ..., 11= (11 choose 3) * (1/2)^3 * (1/2)^(11 - 3) + (11 choose 4) * (1/2)^4 * (1/2)^(11 - 4) + ... + (11 choose 11) * (1/2)^11 * (1/2)^(11 - 11)= 165/2048 + 330/2048 + 462/2048 + 462/2048 + 330/2048 + 165/2048 + 55/2048 + 11/2048 + 1/2048= 1023/2048
Therefore, there are 1023 possible outcomes that contain at least three heads if the coin is flipped 11 times.3.
How many possible outcomes contain the same number of heads and tails if the coin is flipped 8 times?
In this case, we need to find the possible number of outcomes that contain the same number of heads and tails in 8 coin flips. Since there are only 8 flips, we can count the possible outcomes manually.
We can start by considering the case where there is only 1 head and 1 tail.
There are 8 choose 1 way to choose the position of the head, and the rest of the positions must be tails.
Therefore, there are 8 possible outcomes in this case.
Next, we can consider the case where there are 2 heads and 2 tails.
There are 8 choose 2 ways to choose the positions of the heads, and the rest of the positions must be tails.
Therefore, there are (8 choose 2) = 28 possible outcomes in this case.
Finally, we can consider the case where there are 4 heads and 4 tails.
There is only one way to arrange the 4 heads and 4 tails in this case.

The truncation error is O(h^2) = O(0.6^2) = O(0.36).
Given function is,
g(x) = 2/|x|+3 sin(x) +1g'(x) can be approximated using the central finite difference formula with step size h = 0.
Using the central finite difference formula,
we haveg'(x) = [g(x + h) - g(x - h)] / 2h
The derivative of g(x) with respect to x isg'(x) = -2/(x^2) + 3 cos(x)
Also, we are given that g(0.6), g(0), and g(1) are known.
Using the Taylor's theorem to approximate g'(x),
we have
g(x + h) = g(x) + hg'(x) + (h^2/2) g''(c1) ......... (1)
g(x - h) = g(x) - hg'(x) + (h^2/2) g''(c2) ........ (2)
where c1 lies between x and x + h and c2 lies between x - h and x.
Substituting equations (1) and (2) in the central finite difference formula and rearranging terms,
we have
g'(x) = [g(x + h) - g(x - h)] / 2h
= [g(x) + hg'(x) + (h^2/2) g''(c1) - g(x) + hg'(x) - (h^2/2) g''(c2)] / 2h

where g''(c1) and g''(c2) are the second derivatives of g(x) evaluated at c1 and c2, respectively.
To find a formula to approximate g'(0), we use the above formula with x = 0.
Thus,g'(0) = [g(0 + h) - g(0 - h)] / 2h - (h/2) [g''(c1) + g''(c2)]
Putting x = 0 and h = 0.6 in the above formula, we have
g'(0) ≈ [g(0.6) - g(-0.6)] / 1.2 - (0.6/2) [g''(c1) + g''(c2)] ........ (4)
where c1 lies between 0 and 0.6 and c2 lies between -0.6 and 0.
Substituting the given values of g(0.6), g(0), and g(1) in equation (4), we have
g'(0) ≈ [g(0.6) - g(-0.6)] / 1.2 - (0.6/2) [g''(c1) + g''(c2)]
= [2/0.6 + 3 sin(0.6) + 1 - (2/0.6 + 3 sin(-0.6) + 1)] / 1.2 - (0.6/2) [g''(c1) + g''(c2)]

Therefore, Jessica's rate is 12.5 miles per hour.
To find Jessica's rate in miles per hour, we need to determine the total distance she traveled and the total time it took her.
Given that Jessica is walking home, we can consider the distance from her friend's house to her home as the positive direction. Let's denote this distance as "d" in miles.
From the information provided, we know that Jessica is 1.1 miles from home after 2 minutes and 0.6 miles from home after 12 minutes.
Let's set up a proportion to find the total distance she traveled (d) in miles:
(d - 0) / (12 - 2) = (1.1 - 0.6) / (2 - 0)
Simplifying the proportion:
d / 10 = 0.5 / 2
Cross-multiplying:
2d = 10 * 0.5
2d = 5
d = 5 / 2
So, Jessica traveled a total distance of 2.5 miles.
Now, let's find the total time it took her. The time from her friend's house to her home can be represented as "t" in hours.
We know that Jessica took 12 minutes to travel 0.6 miles. Let's convert this to hours:
t = 12 minutes / 60 (conversion to hours)
t = 0.2 hours
Therefore, Jessica took a total of 0.2 hours to travel from her friend's house to her home.
To calculate her rate in miles per hour, we can use the formula:

1. Use forward, backward and central difference to estimate the first and second derivative of f (x) = cosh(x) at x = 2 ,using step size h = 0.01 (in 8 decimal places)
The first and second derivatives of f(x) = cosh(x) at x = 2 can be estimated using forward, backward, and central difference methods with a step size of h = 0.01. The estimations are accurate up to 8 decimal places.
To estimate the first derivative using forward difference, we can use the formula:
f'(x) ≈ (f(x + h) - f(x)) / h
Substituting the values, we have:
f'(2) ≈ (f(2 + 0.01) - f(2)) / 0.01
≈ (cosh(2.01) - cosh(2)) / 0.01
Similarly, the first derivative can be estimated using backward difference with the formula:
f'(x) ≈ (f(x) - f(x - h)) / h
So, for x = 2:
f'(2) ≈ (f(2) - f(2 - 0.01)) / 0.01
≈ (cosh(2) - cosh(1.99)) / 0.01
For the estimation of the second derivative using the central difference, we can use the formula:
f''(x) ≈ (f(x + h) - 2f(x) + f(x - h)) / h^2
Substituting the values, we have:
f''(2) ≈ (f(2 + 0.01) - 2f(2) + f(2 - 0.01)) / 0.01^2
≈ (cosh(2.01) - 2cosh(2) + cosh(1.99)) / 0.0001
By evaluating these formulas, we can obtain numerical approximations of the first and second derivatives of f(x) = cosh(x) at x = 2 with a step size of h = 0.01.

D) s'= 6t^5 - 9/t^2 - 6/t^3
The correct derivative of the given function is option D) s' = 6t^5 - 9/t^2 - 6/t^3.
To find the derivative of the given function, we can use the quotient rule. The quotient rule states that if we have a function of the form f(t) = g(t)/h(t), then its derivative f'(t) can be calculated as:
f'(t) = (g'(t) * h(t) - g(t) * h'(t)) / (h(t))^2
Let's apply the quotient rule to the given function:
s = (t^8 + 9t + 3) / t^2
Using the quotient rule, we differentiate the numerator and denominator separately:
g(t) = t^8 + 9t + 3
g'(t) = 8t^7 + 9
h(t) = t^2
h'(t) = 2t
Now, we can substitute these values into the quotient rule formula:
s' = (g'(t) * h(t) - g(t) * h'(t)) / (h(t))^2
= ((8t^7 + 9) * t^2 - (t^8 + 9t + 3) * 2t) / (t^2)^2
= (8t^9 + 9t^2 - 2t^9 - 18t^2 - 6t) / t^4
= 6t^9 - 9t^2 - 6t / t^4
= 6t^5 - 9/t^2 - 6/t^3
Therefore, the derivative of the given function is s' = 6t^5 - 9/t^2 - 6/t^3, which matches option D.

find the exact location of all the relative and absolute extrema of the function. (order your answers from smallest to largest x.) f(x) = 2x2 − 8x 2 with domain [0, 3]
The function f(x) = 2x2 − 8x 2 with domain [0, 3] has the following relative and absolute extrema: Relative maximum at x = 1 and relative minimum at x = 2.Absolute maximum at x = 0 and absolute minimum at x = 3.
To find the extrema of the function f(x) = 2x2 − 8x 2 with domain [0, 3], we need to find the critical points and then determine whether they correspond to relative maxima, relative minima, or neither. We also need to check the endpoints of the domain to determine whether they correspond to absolute maxima or absolute minima.1. Find the critical points: Critical points are values of x at which the derivative of the function is zero or undefined. To find the derivative of f(x), we use the power rule:f '(x) = 4x − 8Setting this equal to zero, we get:4x − 8 = 0x = 2. This is the only critical point in the interval [0, 3].2. Determine whether the critical point corresponds to a relative maximum, relative minimum, or neither:To determine the nature of the critical point, we need to examine the sign of the derivative on either side of x = 2. We construct a sign chart: xf '(x)0−82−4+84+8From the sign chart, we see that f '(x) changes sign from negative to positive at x = 2, so this critical point corresponds to a relative minimum of f(x).3. Check the endpoints of the domain: We need to evaluate the function at the endpoints of the interval [0, 3] to determine whether they correspond to absolute maxima or absolute minima.f(0) = 0f(3) = −18Therefore, the absolute maximum of f(x) on [0, 3] occurs at x = 0, and the absolute minimum occurs at x = 3.Thus, the function f(x) = 2x2 − 8x 2 with domain [0, 3] has a relative maximum at x = 1 and a relative minimum at x = 2. The absolute maximum of f(x) on [0, 3] occurs at x = 0, and the absolute minimum occurs at x = 3.
