Answer:

The slope is \frac{1}{2}

Step-by-step explanation:

The slope formula is \frac{y2-y1}{x2-x1}

(8, 7) is (x1, y1)

(4, 5) is (x2, y2)

Plug in the values:

\frac{5-7}{4-8}

solve:

\frac{-2}{-4}

\frac{1}{2}

The slope is \frac{1}{2}

The value of 33 + 42 = ___.
frez [133]

Answer:

75

Step-by-step explanation:

We line up the tens place of 33 and 42 as well as the ones place so that it looks like:

33

--------

Then we add first the ones, which is 3 + 2 for 5. Then we add the tens together, 3 + 4 is 7. We put the five first since its in the ones place and the 7 second since its in the tens place for 75.

Ap calc multiple choice question; attached below<br> please explain how, please!
anygoal [31]

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>

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

And we have our final answer!
