Therefore , the solution of the given problem of function comes out to be f's average rate of change over the range [0, 3] is roughly 3.862.

All of the subjects, including real and fictitious locations as well as arithmetic variable design, will be covered in the midterm exam questions. a schematic illustrating the connections between various components that work together to produce the same outcome. A service is made up of many unique parts that work together to produce unique outcomes for each input.

Here,

f(b) – f(a) = average rate of change (b - a)

Since a = 0 and b = 3 in this instance, we get:

typical rate of change is equal to f(3) - f(0) /. (3 - 0)

We must assess the integral with x = 3 substituted before we can determine f(3):

From x=0 to x=3, compute f(3) = t3 + 2 dx.

By substituting u = t³ + 2, du = 3t² dt, we can assess this integral:

=> f(3) = ∫√(t³ + 2) dt evaluated from t=0 to t=3

=>  (1/3) * ∫√u du evaluated from u=2 to u=29

=>  (1/3) * [(2/3) * (29^(3/2) - 2^(3/2))]

=>   11.585

Simply enter x = 0 into the integral and assess it to obtain f(0):

Evaluation of f(0) = t³ + 2 dx from x=0 to x=3 = 0

Therefore, the average rate of change of f over the range [0, 3]

Average rate of change is

=> (11.585 - 0) / 3 - (f(3) - f(0))

=>   3.862

Therefore, f's average rate of change over the range [0, 3] is roughly 3.862.

the first order pair is always x and the second is y

slope m =Y2_Y1 ÷ X2_X1

then 24_ 17 ÷3 _2= 7

The required y-coordinate of the third point is 17. Therefore, the ordered pair is (8,17).

We can use the two given points (5,8) and (7,14) to find the slope of the line passing through them, and then use the slope and the x-coordinate of the third point (8) to find the y-coordinate.

The slope of a line passing through two points (x1,y1) and (x2,y2) is given by:

[tex]$m = \frac{y2-y1}{x2-x1}$$[/tex]

Using the points (5,8) and (7,14), we get:

[tex]$m = \frac{14-8}{7-5} = \frac{6}{2} = 3$$[/tex]

So the slope of the line passing through these two points is 3.

Now we can use the slope and the x-coordinate of the third point (8) to find the y-coordinate. We use the point-slope form of the equation of a line:

[tex]$y - y1 = m(x - x1)$[/tex]

where (x1,y1) is one of the given points, and m is the slope.

Using the point (5,8), we get:

y - 8 = 3(x - 5)

Simplifying this equation, we get:

y = 3x - 7

Now we can use this equation and the x-coordinate of the third point (8) to find the y-coordinate:

y = 3(8) - 7 = 17

So the y-coordinate of the third point is 17. Therefore, the ordered pair is (8,17).

Step-by-step explanation:

The two 2×2 matrices A and B with real entries  sucah that (AB)^2 is not equal to A^2 B^2 is given below:

Let A = [[1, 0], [0, -1]] and B = [[0, 1], [1, 0]] be two 2x2 matrices with real entries. Then,

AB = [[0, 1], [-1, 0]] and AB^2 = [[-1, 0], [0, -1]]

A^2 = [[1, 0], [0, 1]] and B^2 = [[0, 1], [1, 0]]

So, A^2B^2 = [[0, 1], [1, 0]] and (AB)^2 = ABAB = [[0, 1], [-1, 0]][[0, 1], [-1, 0]] = [[-1, 0], [0, -1]]

Step-by-step explanation:

The APR for the loan given is $105.8

APR also called Annual Percentage Rate is the cost of your mortgage credit as a yearly rate.

To get the APR , we have to calculate the total amount paid in 24 months.

The total amount paid in 24 months = 24 × 167.15

= $4011.6

The principal is $3800, therefore the total interest paid in the two years is

I = A-P

I = 4011.6-3800

I = $211.6

Since APR is annual , then we need to calculate the interest for a year

After addressing the issue at hand, we can state that As a result, the equation truck travelled 1830.18 miles between fill-ups.

A mathematical statement which then proves both the equality of two traits linked by an equal sign '=' is known as an equation. 2x - 5 = 13, for example. 2x-5 and 13 are two expressions. The symbol '=' connects the two expressions. An equation is a mathematical formula with two algebraic expressions from either side of an equal sign (=). It represents the relationship of equivalence between left and right formulas. In any formula, LHS = RHS (left side = right side).

Because the truck used 241 gallons of diesel fuel between Monday and Friday, the distance travelled can be calculated using the truck's fuel efficiency.

T Previous fill-up odometer reading = 78467

At the current fill-up, the odometer reads 80293

Traveled distance = 80293 - 78467 = 1826 miles

241 gallons of fuel were consumed.

Mileage = Distance travelled / Fuel Consumption

Mileage = 1826 divided by 241

7.58 miles per gallon = mileage

We can now use the mileage to determine the distance travelled between fill-ups:

Distance travelled = Fuel consumption x Mileage

241 divided by 7.58 equals the distance travelled.

The total distance travelled is 1830.18 miles.

As a result, the truck travelled 1830.18 miles between fill-ups.

The equation of the graph is option (c) i.e. y = 0.5 csc [0.5(x + π/2)] - 1 which is solve below.

In elementary mathematics, term "graph" denotes a plot or a function graph. A graph, in the language of mathematicians, a set of points and connections between some subset of those points (which may empty).

If the equation y = A csc (B(x + C)) + D

Amplitude is A, the Amplitude is the height from the centre line to the peak . Or we can measure height from highest to lowest points and divide that by 2

Period is 2π/B, the Period goes from one peak to the next

Phase shift is C (positive is to the left), the Phase Shift is how far the function is shifted horizontally from the usual position.

Vertical shift is D, Vertical Shift is how far the function is shifted vertically from the usual position.

If y = csc(x), then A = 1 , B = 1 , C = 0 , D = 0

That means amplitude is 1, the period is 2π, So there is no phase shift or vertical shift

Now lets solve the problem from the graph

[tex]The\ amplitude = \frac{(-0.5 - (-1.5))}{2} = 0.5[/tex]

∴ [tex]A = 0.5[/tex]

The period is from 2.5π to -1.5π

∴ [tex]The \ period\ is\ 4\pi[/tex]

∵ [tex]The\ period = \frac{2\pi }{B}[/tex]

∴ [tex]4\pi = \frac{2\pi }{B}, by\ cross \ multiplication[/tex]

∴ [tex]B = \frac{2\pi }{4\pi } = \frac{1}{2} = 0.5[/tex]

There is only one answer which has value A = 0.5 and B = 0.5

∴ y = 0.5 csc[0.5(x + π/2)] - 1

Answer:

I, IV, V

Step-by-step explanation:

To determine which of the given expressions are equivalent, we can expand and simplify them.

I. (x - 4)² - 1

Expanding the square, we get:

(x - 4)² = x² - 8x + 16

So, (x - 4)² - 1 = x² - 8x + 15

II. x² - 8x - 17

III. x² + 15

IV. x² - 8x + 15

V. (x - 5)(x - 3)

Expanding the product, we get:

(x - 5)(x - 3) = x² - 8x + 15

VI. x² - 17

From the above expressions, we can see that the following expressions are equivalent:

I. (x - 4)² - 1 and IV. x² - 8x + 15

Also, V. (x - 5)(x - 3) is equivalent to both I. and IV.

Therefore, the answer is (C) I, IV, V.

Answer: 30 Child tickets 6 Adult tickets.

Step-by-step explanation:

Set up your system of equations to solve.

36 tickets are purchased, meaning a number of child tickets, and a different number of adult tickets add up to 36. We can write this as x+y=36.

The price of the tickets add up to 252 dollars. We can write this as 6 (the child price) times x + 12 (the adult price) times y = 252

So, x+y=36 and 6x+12y=252.

I will solve this using the substitution method.

So, first, we need to isolate a variable, I will choose the first equation to do so.

x+y=36 ---> x=36-y

Now, plug the value of x into the second equation.

6(36-y)+12y=252.

Distribute.

216-6y+12y=252

Combine like terms.

216+6y=252.

Subtract 216 from both sides.

6y=36

Divide by 6 on both sides.

y=6

Now plug this value of y into the previous equation to get x.

x+6=36

Subtract 6 from both sides.

x=30

Remember x was children's tickets and y was adult tickets. (It is better to use variables like C and A in this case).

Sure hope this helps you

The answer of the question based on the rate of interest is a)  $23,900, b) $1,146.37 c) $1,289.78.

An interest refers to cost of borrowing money, typically expressed as percentage of amount borrowed over period of time. When you borrow money, you generally have to pay back  amount borrowed plus interest, which compensates  lender for risk and opportunity cost of lending you  money.

a) The down payment is 10% of the home price, which is:

10% of $239,000 = 0.10 x $239,000 = $23,900

To find the loan amount, we subtract the down payment from the home price:

Loan amount = $239,000 - $23,900 = $215,100

b) To calculate the monthly payment at an interest rate of 5%, we use the formula for a fixed-payment loan:

M = P * r * (1 + r)^n / ((1 + r)^n - 1)

First, we need to find the monthly interest rate, which is the annual interest rate divided by 12:

Monthly interest rate = 5% / 12 = 0.00416667

Total number of payments = 30 years x 12 months/year = 360

Now we can plug in these values to find the monthly payment:

M = $215,100 * 0.00416667 * (1 + 0.00416667)^360 / ((1 + 0.00416667)^360 - 1) = $1,146.37

Therefore, the monthly payment at an interest rate of 5% is $1,146.37.

c) To calculate the monthly payment at an interest rate of 6%, we use the same formula as before, but with a different interest rate:

Monthly interest rate = 6% / 12 = 0.005

Total number of payments = 30 years x 12 months/year = 360

M = $215,100 * 0.005 * (1 + 0.005)^360 / ((1 + 0.005)^360 - 1) = $1,289.78

Therefore, the monthly payment at an interest rate of 6% is $1,289.78.
