Clear out any fractions by Multiplying every term by the bottom parts. Add or Subtract the same value from both sides. Divide every term by the same nonzero value. Combine Like Terms. Factoring. Expanding (the opposite of factoring) may also help.

Answer:

none of the above; $531.71

Step-by-step explanation:

Fill in the given numbers and do the arithmetic.

A = $360·e^(0.13·3) = $360·e^0.39 ≈ $360·1.1.47698

A ≈ $531.71

___

Water flowed out of a tank at a steady rate. A total of 18 1/2 gallons flowed out of the tank in 4 1/4 hours. Which expression

Alecsey [184]

Answer:

In 1 hour water flowed out = $\frac{74}{17}$ gallons

Step-by-step explanation:

Given as ,

The quantity of water flowed out of tank = 18 $\frac{1}{2}$ gallons

= $\frac{37}{2}$ gallons

The time spend in flowing water out of tank = 4 $\frac{1}{4}$ hours

= $\frac{17}{4}$ hours

∵ In $\frac{17}{4}$ hours , water flowed out = $\frac{37}{2}$

∴ In 1 hours , water flowed out = $\frac{37\times4} {17\times2}$

So, in 1 hour water flowed out = $\frac{74}{17}$ gallons Answer

Use the squared identities to simplify 2sin^2 x cos^2 x

guapka [62]

The given question is

$2sin^2 x cos^2 x$

Multiplying and divide by 2

$\frac{4sin^2 x cos^2 x}{2} =\frac{(2 sinx cos x})^2{2}=\frac{sin^2(2x)}{2}$

Again multiplying and dividing by 2

$\frac{2sin^2(2x)}{4}$

And

$2 sin^2(2x)=1-cos(4x)$

So we will get

$\frac{1-cos(4x)}{4}$

Correct option is D
