The solution to the equation is -1.5 or -3/2.

We have the equation:

x² + 3-2x= 1+ x² +5

Combine Terms and subtract x² from both sides:

x² - x² + 3 -2x = 1 + 5 + x² - x²

3 -2x = 1 + 5

Add:

3 -2x = 6

Combine Terms and subtract 3 from both sides:

-2x + 3 -3 = 6 - 3

-2x = 3

Dividing by -2 we get:

x = 3/(-2)

x = -3/2

The solution to the equation (2)/(x+3) + (5)/(x-3) = (37)/(x^(2)-9) is obtained by finding the values of x that satisfy the expanded equation 7x^3 + 9x^2 - 63x - 118 = 0 using numerical methods.

To solve the rational equation (2)/(x+3) + (5)/(x-3) = (37)/(x^2 - 9), we will follow a systematic approach.

Step 1: Identify any restrictions

Since the equation involves fractions, we need to check for any values of x that would make the denominators equal to zero, as division by zero is undefined.

In this case, the denominators are x + 3, x - 3, and x^2 - 9. We can see that x cannot be equal to -3 or 3, as these values would make the denominators equal to zero. Therefore, x ≠ -3 and x ≠ 3 are restrictions for this equation.

Step 2: Find a common denominator

To simplify the equation, we need to find a common denominator for the fractions involved. The common denominator in this case is (x + 3)(x - 3) because it incorporates both (x + 3) and (x - 3).

Step 3: Multiply through by the common denominator

Multiply each term of the equation by the common denominator to eliminate the fractions. This will result in an equation without denominators.

[(2)(x - 3) + (5)(x + 3)](x + 3)(x - 3) = (37)

Simplifying:

[2x - 6 + 5x + 15](x^2 - 9) = 37

(7x + 9)(x^2 - 9) = 37

Step 4: Expand and simplify

Expand the equation and simplify the resulting expression.

7x^3 - 63x + 9x^2 - 81 = 37

7x^3 + 9x^2 - 63x - 118 = 0

Step 5: Solve the cubic equation

Unfortunately, solving a general cubic equation algebraically can be complex and involve advanced techniques. In this case, solving the equation directly may not be feasible using elementary methods.

To obtain the specific values of x that satisfy the equation, numerical methods or approximations can be used, such as graphing the equation or using numerical solvers.

The probability of rolling a 1 on a die or rolling an even number on a die is 1/3. This is because the probability of rolling a 1 is 1/6, the probability of rolling an even number is 1/2

The probability of rolling a 1 on a die or rolling an even number on a die is P(E) = P(rolling a 1) + P(rolling an even number).

There are six possible outcomes of rolling a die: 1, 2, 3, 4, 5, or 6.

There are three even numbers: 2, 4, and 6. So, the probability of rolling an even number is 3/6, which simplifies to 1/2 or 0.5.

The probability of rolling a 1 is 1/6.

Therefore, P(E) = 1/6 + 1/2 = 2/6 or 1/3.

The correct answer is P(E) = P(rolling a 1) + P(rolling an even number).

If we roll a die, then there are six possible outcomes, which are 1, 2, 3, 4, 5, and 6.

There are three even numbers, which are 2, 4, and 6, and there is only one odd number, which is 1.

Thus, the probability of rolling an even number is P(even) = 3/6 = 1/2, and the probability of rolling an odd number is P(odd) = 1/6.

The question asks for the probability of rolling a 1 or an even number. We can solve this problem by using the addition rule of probability, which states that the probability of A or B happening is the sum of the probabilities of A and B, minus the probability of both A and B happening.

We can write this as:

P(1 or even) = P(1) + P(even) - P(1 and even)

However, the probability of rolling a 1 and an even number at the same time is zero, because they are mutually exclusive events.

Therefore, P(1 and even) = 0, and we can simplify the equation as follows:P(1 or even) = P(1) + P(even) = 1/6 + 1/2 = 2/6 = 1/3

In conclusion, the probability of rolling a 1 on a die or rolling an even number on a die is 1/3. This is because the probability of rolling a 1 is 1/6, the probability of rolling an even number is 1/2, and the probability of rolling a 1 and an even number at the same time is 0. To solve this problem, we used the addition rule of probability and found that P(1 or even) = P(1) + P(even) - P(1 and even) = 1/6 + 1/2 - 0 = 1/3. Therefore, the answer is P(E) = P(rolling a 1) + P(rolling an even number).

Therefore, f'(1) = 8 cos 1.Therefore, f'(x) = (4 + 4x) cos x + (4 - 4x) sin x.

Given that f(x) = 4x (sin x + cos x)

To find: f'(x) = , f'(1)

=​f(x)

= 4x (sin x + cos x)

Taking the derivative of f(x) with respect to x, we get;

f'(x) = (4x)' (sin x + cos x) + 4x [sin x + cos x]

'f'(x) = 4(sin x + cos x) + 4x (cos x - sin x)

f'(x) = 4(cos x + sin x) + 4x cos x - 4x sin x

f'(x) = 4 cos x + 4x cos x + 4 sin x - 4x sin x

f'(x) = (4 + 4x) cos x + (4 - 4x) sin x

Therefore, f'(x) = (4 + 4x) cos x + (4 - 4x) sin x.

Using the chain rule, we can find the derivative of f(x) with respect to x as shown below:

f(x) = 4x (sin x + cos x)

f'(x) = 4 (sin x + cos x) + 4x (cos x - sin x)

f'(x) = 4 cos x + 4x cos x + 4 sin x - 4x sin x

The answer is: f'(x) = 4 cos x + 4x cos x + 4 sin x - 4x sin x.

To find f'(1), we substitute x = 1 in f'(x)

f'(1) = 4 cos 1 + 4(1) cos 1 + 4 sin 1 - 4(1) sin 1

f'(1) = 4 cos 1 + 4 cos 1 + 4 sin 1 - 4 sin 1

The derivative of

f(x)=(-3x-12) (x²−4x+16)

is given by

f'(x) = -6x² - 12x + 48,

which is option (c).

Let us find the derivative of f(x)=(-3x-12) (x²−4x+16)

Below, we have provided the steps to find the derivative of the given function using the product rule of differentiation.The product rule states that: if two functions u(x) and v(x) are given, the derivative of the product of these two functions is given by

u(x)*dv/dx + v(x)*du/dx,

where dv/dx and du/dx are the derivatives of v(x) and u(x), respectively. In other words, the derivative of the product of two functions is equal to the derivative of the first function multiplied by the second plus the derivative of the second function multiplied by the first.

So, let's start with differentiating the function. To make it easier, we can start by multiplying the two terms in the parenthesis:

f(x)= (-3x -12)(x² - 4x + 16)

f(x) = (-3x)*(x² - 4x + 16) - 12(x² - 4x + 16)

Applying the product rule, we get;

f'(x) = [-3x * (2x - 4)] + [-12 * (2x - 4)]

f'(x) = [-6x² + 12x] + [-24x + 48]

Combining like terms, we get:

f'(x) = -6x² - 12x + 48

Therefore, the derivative of

f(x)=(-3x-12) (x²−4x+16)

is given by

To maximize the objective function 5x + 4y over the feasible set, we need to find the corner points of the feasible region and evaluate the objective function at those points. The maximum value of the objective function will occur at one of these corner points.

Let's say the constraints that define the feasible set are:

f(x, y) = x + y <= 5

g(x, y) = x - y >= -3

h(x, y) = y >= 0

Graphing these inequalities on a coordinate plane, we can see that the feasible set is a triangular region with vertices at (1, 2), (-3, 0), and (-1.5, 0).

To find the maximum value of the objective function, we evaluate it at each of these corner points:

At (1, 2): 5(1) + 4(2) = 13

At (-3, 0): 5(-3) + 4(0) = -15

At (-1.5, 0): 5(-1.5) + 4(0) = -7.5

b. To find the probability of at most 28 dogs being spayed or neutered, we sum the probabilities from 0 to 28:

P(X <= 28) = P(X = 0) + P(X = 1) + ... + P(X = 28)

c. To find the probability of at least 28 dogs being spayed or neutered, we subtract the probability of fewer than 28 dogs being spayed or neutered from 1:

P(X >= 28) = 1 - P(X < 28)

d. To find the probability of between 26 and 32 dogs being spayed or neutered (inclusive), we sum the probabilities from 26 to 32:

P(26 <= X <= 32) = P(X = 26) + P(X = 27) + ... + P(X = 32)

By substituting the appropriate values into the binomial probability formula and performing the calculations, we can find the probabilities for each scenario.

Two customers, A and B, are due to arrive at a lawyer's office during the same hour from 10:00 to 11:00. Their actual arrival times, denoted by X and Y respectively, are independent of each other and uniformly distributed during the hour.

(a) Denote the time as X = Uniform(10, 11).

Then, P(X > 10.45) = 1 - P(X <= 10.45) = 1 - (10.45 - 10) / 60 = 0.25

Similarly, P(Y > 10.45) = 0.25

Then, the probability that both customers arrive within the last 15 minutes is:

P(X > 10.45 and Y > 10.45) = P(X > 10.45) * P(Y > 10.45) = 0.25 * 0.25 = 0.0625.

(b) The probability that A arrives first is P(A < B).

This is equal to the area under the diagonal line X = Y. Hence, P(A < B) = 0.5

The probability that B arrives more than 30 minutes after A is P(B > A + 0.5) = 0.25, since the arrivals are uniformly distributed between 10 and 11.

Therefore, the probability that A arrives first and B arrives more than 30 minutes after A is given by:

P(A < B and B > A + 0.5) = P(A < B) * P(B > A + 0.5) = 0.5 * 0.25 = 0.125.

(c) Find the probability that B arrives first provided that both arrive during the last half-hour.

The probability that both arrive during the last half-hour is 0.5.

Denote the time as X = Uniform(10.30, 11).

Then, P(X < 10.45) = (10.45 - 10.30) / (11 - 10.30) = 0.4545

Similarly, P(Y < 10.45) = 0.4545

The probability that B arrives first, given that both arrive during the last half-hour is:

P(Y < X) / P(Both arrive in the last half-hour) = (0.4545) / (0.5) = 0.909 or 90.9%

The slope is m = 4 and the y-intercept is 10, so the linear function becomes:y = 4x + 10 and the appropriate linear function is y = 3x - 25.

A) To find the linear function with a slope of m = 4 and y-intercept of 10, we can use the slope-intercept form of a linear equation, y = mx + b, where m is the slope and b is the y-intercept.

In this case, the slope is m = 4 and the y-intercept is 10, so the linear function becomes:

y = 4x + 10

B) To find the linear function with a slope of m = 3 and passing through the point (8, -1), we can use the point-slope form of a linear equation, y - y1 = m(x - x1), where m is the slope and (x1, y1) is a point on the line.

In this case, the slope is m = 3 and the point (x1, y1) = (8, -1), so the linear function becomes:

y - (-1) = 3(x - 8)

y + 1 = 3(x - 8)

y + 1 = 3x - 24

y = 3x - 25

Therefore, the appropriate linear function is y = 3x - 25.

A)  The y-intercept of 10 indicates that the line intersects the y-axis at the point (0, 10), where the value of y is 10 when x is 0.

The line with slope m = 4 and y-intercept of 10 can be represented by the linear function y = 4x + 10.

This means that for any given value of x, the corresponding y-value on the line can be found by multiplying x by 4 and adding 10. The slope of 4 indicates that for every increase of 1 in x, the y-value increases by 4 units.

B) When x is 8, the value of y is -1.

To find the equation of the line with slope m = 3 passing through the point (8, -1), we can use the point-slope form of a linear equation, which is y - y1 = m(x - x1), where (x1, y1) is a point on the line.

Plugging in the values, we have y - (-1) = 3(x - 8), which simplifies to y + 1 = 3x - 24. Rearranging the equation gives y = 3x - 25. Therefore, the appropriate linear function is y = 3x - 25. This means that for any given value of x, the corresponding y-value on the line can be found by multiplying x by 3 and subtracting 25. The slope of 3 indicates that for every increase of 1 in x, the y-value increases by 3 units. The line passes through the point (8, -1), which means that when x is 8, the value of y is -1.

The equation of the line passing through the points (21, 26) and (2, 7) in slope-intercept form is y = (19/19)x + (7 - (19/19)2), which simplifies to y = x + 5.

To find the equation of the line, we can use the slope-intercept form of a linear equation, which is y = mx + b, where m represents the slope and b represents the y-intercept.

First, we need to find the slope (m) of the line. The slope is calculated using the formula: m = (y₂ - y₁) / (x₂ - x₁), where (x₁, y₁) and (x₂, y₂) are the coordinates of the two points on the line.

Let's substitute the coordinates (21, 26) and (2, 7) into the slope formula:

m = (7 - 26) / (2 - 21) = (-19) / (-19) = 1

Now that we have the slope (m = 1), we can find the y-intercept (b) by substituting the coordinates of one of the points into the slope-intercept form.

Let's choose the point (2, 7):

7 = (1)(2) + b

7 = 2 + b

b = 7 - 2 = 5

Finally, we can write the equation of the line in slope-intercept form:

y = 1x + 5

Therefore, the equation of the line that contains the given pair of points (21, 26) and (2, 7) is y = x + 5.

To write the slope-intercept form of the equation of the line containing the point (5, -8) and parallel to 3x - 7y = 9, we need to follow these steps.

Step 1: Find the slope of the given line.3x - 7y = 9 can be rewritten in slope-intercept form y = mx + b as follows:3x - 7y = 9 ⇒ -7y = -3x + 9 ⇒ y = 3/7 x - 9/7.The slope of the given line is 3/7.

Step 2: Determine the slope of the parallel line. A line parallel to a given line has the same slope.The slope of the parallel line is also 3/7.

Step 3: Write the equation of the line in slope-intercept form using the point-slope formula y - y1 = m(x - x1) where (x1, y1) is the given point on the line.

Plugging in the point (5, -8) and the slope 3/7, we get:y - (-8) = 3/7 (x - 5)⇒ y + 8 = 3/7 x - 15/7Multiplying both sides by 7, we get:7y + 56 = 3x - 15 Rearranging, we get:

3x - 7y = 71 Thus, the slope-intercept form of the equation of the line containing the point (5, -8) and parallel to 3x - 7y = 9 is y = 3/7 x - 15/7 or equivalently, 3x - 7y = 15.

(b)(ii)  The maximum height of the ferris wheel car above the ground is 30.79 meters.

To find the maximum and minimum height of the ferris wheel car above the ground, we need to find the maximum and minimum values of the function h(t).

The function h(t) is of the form h(t) = a + b sin(c t), where a = 15.55, b = 15.24, and c = 8π. The maximum and minimum values of h(t) occur when sin(c t) takes on its maximum and minimum values of 1 and -1, respectively.

Maximum height:

When sin(c t) = 1, we have:

h(t) = a + b sin(c t)

= a + b

= 15.55 + 15.24

= 30.79

Therefore, the maximum height of the ferris wheel car above the ground is 30.79 meters.

Minimum height:

When sin(c t) = -1, we have:

h(t) = a + b sin(c t)

= a - b

= 15.55 - 15.24

= 0.31

Therefore, the minimum height of the ferris wheel car above the ground is 0.31 meters.

Note that the diameter of the ferris wheel is not used in this calculation, as it only provides information about the physical size of the wheel, but not its height at different times.

Ali's teammate ran 37 kilometers in the week. The equation k + 11 = 48 can be used to determine the number of kilometers Ali's teammate ran.

Let's represent the number of kilometers Ali's teammate ran in the week as "k." We know that Ali ran 11 kilometers more than his teammate, so Ali's total distance can be represented as k + 11. Since Ali ran 48 kilometers in total, we can set up the equation k + 11 = 48 to determine the value of k. By subtracting 11 from both sides of the equation, we get k = 48 - 11, which simplifies to k = 37. Therefore, Ali's teammate ran 37 kilometers in the week. The equation k + 11 = 48 can be used to determine the number of kilometers Ali's teammate ran. Let x be the number of kilometers Ali's teammate ran in the week.Therefore, we can form the equation:x + 11 = 48Solving for x, we subtract 11 from both sides to get:x = 37Therefore, Ali's teammate ran 37 kilometers in the week.

The revenue can be calculated by multiplying the selling price per Frisbee ($7) , company must sell 2000 Frisbees to break even. The answer is option C. 2000.

In the first year, a Frisbee company's operating cost is $10,000 plus $2 for each Frisbee.

The company sells each Frisbee for $7.

The number of Frisbees the company must sell to break even is the point where its revenue equals its expenses.

To determine the number of Frisbees the company must sell to break even, use the equation below:

Revenue = Expenseswhere, Revenue = Price of each Frisbee sold × Number of Frisbees sold

Expenses = Operating cost + Cost of producing each Frisbee

Using the values given in the question, we can write the equation as:

To break even, the revenue should be equal to the cost.

Therefore, we can set up the following equation:

$7 * x = $10,000 + $2 * x

Now, we can solve this equation to find the value of x:

$7 * x - $2 * x = $10,000

Simplifying:

$5 * x = $10,000

Dividing both sides by $5:

x = $10,000 / $5

x = 2,000

7x = 2x + 10000

Where x represents the number of Frisbees sold

Multiplying 7 on both sides of the equation:7x = 2x + 10000
