Find the average rate of change of g ( x ) = 7 x 2 + 8 x 3 on the interval [-3, 4].

Answers

The average rate of change of g ( x ) = 7 x 2 + 8 x 3 on the interval [-3, 4] is 111.

According to the given question.

We have a function g(x) = 7x^2 + 8x^3.

And a interval [-3, 4].

As we know that, the average rate of change of y over an interval between 2 points (a, f(a)) and (b, f(b)) is the slope of the secant line connecting the 2 points.

To calculate the average rate of change between the 2 points we use the formula

f(b) - f(a)/ b - a

Therefore, the average rate of change of g ( x ) = 7 x 2 + 8 x 3 on the interval [-3, 4] is given by

[7(4)^2 + 8(4)^3  - 7(-3)^(2) - 8(-3)^3]/4 + 3

= [112 + 512 - 63 + 216]/7

= 777/7

= 111

Hence,  the average rate of change of g ( x ) = 7 x 2 + 8 x 3 on the interval [-3, 4] is 111.

Answer:

D) 41.81 degrees

Step-by-step explanation:

In this problem, we are given a leg length (a=12) and the hypotenuse (c=18).

We need to select which trigonometric identity to use with the acronym SOHCAHTOA:

SOH -> sine=opposite/hypotenuse

CAH -> cosine=adjacent/hypotenuse

TOA -> tangent=opposite/adjacent

Given side a is opposite of angle A and side c is the hypotenuse, we clearly need to use the sine function.

Set up an equation based on the information you have:

sin(A)=12/18

Now take the inverse:

sin^-1(sin(A))=sin^-1(12/18)

A=41.8103149

So the best option is answer D) 41.81 degrees

Step-by-step explanation:

Step 1: Define Equation

1/2x + 4 = 6

Step 2: Solve for x

Subtract 4 on both sides:                    1/2x = 2Divide 1/2 on both sides:                     x = 4

Step 3: Check

Plug in x into the original equation to verify it's a solution.

Substitute in x:                    1/2(4) + 4 = 6Multiply:                               2 + 4 = 6Add:                                     6 = 6

Here we see that 6 does indeed equal 6.

∴ x = 4 is the solution to the equation.

The price of fuel may increase due to demand and decrease due to overproduction. Marco is studying the change in the price of two types of fuel, A and B, over time.


The price f(x), in dollars, of fuel A after x months is represented by the function below:


f(x) = 2.27(0.88)x


Part A: Is the price of fuel A increasing or decreasing and by what percentage per month? Justify your answer. (5 points)


Part B: The table below shows the price g(m), in dollars, of fuel B after m months:



m (number of months) 1 2 3 4

g(m) (price in dollars)3.44 3.30 3.17 3.04



Which type of fuel recorded a greater percentage change in price over the previous month? Justify your answer.

Answers

Answer:

  A. decreasing 12% per month

  B. fuel A recorded the greater change

Step-by-step explanation:

Given an equation and a table of values, you want to compare the rates of change each represents.

A.

The fuel price is described by ...

  f(x) = 2.27(0.88^x)

We recognize this exponential equation to be of the form ...

  f(x) = (initial value) × (growth factor)^x

Comparing parts of the equation, we see ...

  growth factor = 0.88

The relation between growth factor and growth rate is ...

  growth factor = 1 + growth rate

  growth rate = growth factor - 1 = 0.88 -1 = -0.12 = -12%

This tells us the rate of change in fuel price is -12% per month.

B.

To find the percentage change, we can use the formula ...

  percent change = ((new value) / (old value) -1) × 100%

Applied to the first two table values, we have ...

  percent change = (3.30/3.44 -1) × 100% ≈ -4.07%

This decrease of 4.07% is less than the decrease of 12% represented by the equation. Type A fuel recorded the greater percentage change.

Sakura's house is at an elevation between 113 m and 120 m above sea level. Her friend Ted lives about 15 m below her. Choose the compound inequality that describes the elevation x of Ted's house. Part B Ted lives between _____m and _______m above sea level.​

Answers

The compound inequality to describe the elevation of Ted's house is 135 > x > 128.

Ted lives between 128m and 135m above sea level.​

How to explain the inequality?

Now it is given that,

Sakura's house is at an elevation between 113 m and 120 m above sea level.

Let x be the elevation of Sakura's house.

So, 120 > x > 113

Now Ted lives about 15 m below her

Ted's  house elevation = x - 15

So, the compound inequality to describe the elevation of Ted's house,

120 > x - 15 > 113

Adding 15 to the inequality we get,

120 + 15 > x - 15 + 15 > 113 + 15

Solving we get,

135 > x > 128

This is the required compound inequality.

Thus, the compound inequality to describe the elevation of Ted's house is 135 > x > 128.
