<h3>3 Answers: A, C, and F</h3>

All of these equations are in the form Ax+By = C

An equation like x+y = -1 has A = 1, B = 1, C = -1
An equation like x+4y = 0 has A = 1, B = 4, C = 0
An equation like 8x-3y = 20 has A = 8, B = -3, C = 20

Ap calc multiple choice question; attached below<br> please explain how, please!

Answer:

C. $\frac{f(b)-f(1)}{b-1}=20$

General Formulas and Concepts:

<u>Calculus</u>

Mean Value Theorem (MVT) - If f is continuous on interval [a, b], then there is a c∈[a, b] such that $f'(c)=\frac{f(b)-f(a)}{b-a}$

MVT is also Average Value

Step-by-step explanation:

<u>Step 1: Define</u>

$f(x)=e^{2x}$

f'(c) = 20

Interval [1, b]

<u>Step 2: Check/Identify</u>

Function [1, b] is continuous.

Derivative [1, b] is continuous.

∴ There exists a c∈[1, b] such that $f'(c)=\frac{f(b)-f(a)}{b-a}$

<u>Step 3: Mean Value Theorem</u>

Substitute: $20=\frac{ f(b)-f(1)}{b-1}$
Rewrite: $\frac{ f(b)-f(1)}{b-1}=20$

And we have our final answer!

Elena needs to find a table that will fit three cube-shaped cases, each containing a frog.

NikAS [45]

Answer:You could not use a table with a top that is 2 1/2 feet long and 1 1/2 feet wide

Step-by-step explanation:

The complete question is

Elena needs to find a table that will fit three cube-shaped cases, each containing a frog.If the volume of each case is 1,000 cubic inches, could she use a table with a top that measures 2 1/2 feet long and 1 1/2 feet wide?Explain

step 1

Find the length side of the cube-shaped case

we know that

The volume of the cube is equal to

where

b is the length side of the cube

we have

substitute

solve for b

step 2

Convert feet to inches

we have

step 3

Compare the dimensions of the table with the dimensions of the cube-shaped case

30 > 10

The length of the table is greater than the length side of the cube

18> 10

The width of the table is greater than the length side of the cube

therefore

You could not use a table with a top that is 2 1/2 feet long and 1 1/2 feet wide
