In this question, you're trying to find the unit rate in which the teacher can grade tests.

A unit rate is another word for "rate of change".

This means that we have to find how many tests the teacher could grade in 1 minute.

To find the unit rate, divide 18 by 15

18 ÷ 15 = 1.2

This means that Mr. Rivera can grade 1.2 tests in 1 minute.

Answer:

1.2 tests

$12,800 15% is taken out what's the answer

Anuta_ua [19.1K]

Answer:

$10,880

Step-by-step explanation:

15% = 15 ÷ 100 = 0.15

So 15% of 12800 = 0.15 x 12800 = 1920

Therefore, 12800 - 1920 = 10880

12800 x (1 - 0.15) = 10880

F(x) = square root 32x <br> g(x) = square root 2x

otez555 [7]

Given:

The two functions are:

$f(x)=\sqrt{32x}$

$g(x)=\sqrt{2x}$

To find:

The $(f\cdot g)(x)$ . Assume $x\geq 0$ .

Solution:

We have,

$f(x)=\sqrt{32x}$

$g(x)=\sqrt{2x}$

Now,

$(f\cdot g)(x)=f(x)\cdot g(x)$

$(f\cdot g)(x)=\sqrt{32x}\cdot \sqrt{2x}$

$(f\cdot g)(x)=\sqrt{32x\times 2x}$

$(f\cdot g)(x)=\sqrt{64x^2}$

$(f\cdot g)(x)=8x$

Therefore, the correct option is A.
