Hi there!

8 would be the nearest ten of 7.995..

1.Multiply 82 with 0.01:

$82$ · $0.01=0.82$

2.Multiply the terms:

$0.82$ · $9.75=7.995$

3.Round the term:

$7.995=8$

Therefore, 82% of 9.75 in nearest tenth is 8.

Differentiating Exponential functions In Exercise,find the derivative of the function. See Example 2 and 3.

Keith_Richards [23]

Answer: The derivative would be $f'(x)=2(e^{2x}-e^{-2x})$

Step-by-step explanation:

Since we have given that

$f(x)=(e^x+e^{-x})^{\frac{4}{2}}\\\\f(x)=(e^x+e^{-x})^2$

As we will use "Chain Rule"

and at last we will use the identity '' $a^2-b^2=(a-b)(a+b)$ ''

We need to find the derivative of the function:

$f'(x)=2(e^x+e^{-x})(e^x-e^{-x})\\\\f'(x)=2(e^{2x}-e^{-2x})$

Hence, the derivative would be

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

Let F(x)=-7x-12 and g(x)=13-3x. What is f-g?

Oxana [17]

Answer:

$(f - g)x = -4x - 25$

Step-by-step explanation:

Given:

$f(x) = -7x - 12$

$g(x) = 13 - 3x$

Required:

$(f - g)x$

SOLUTION:

$(f - g)x = f(x) - g(x)$

$f(x) - g(x) = (-7x - 12) - (13 - 3x)$

$= -7x - 12 - 13 + 3x$

Collect like terms

$= -7x + 3x - 12 - 13$

$(f - g)x = -4x - 25$

Which of the following is least?

Olegator [25]

In order from least to greatest, it's listed as:

0.015, 0.105, 0.15, 0.501.

0.015 is the lowest number because it is the farthest from being a whole. It starts with .0, whereas the rest of them have a number higher than 0 after the period.
