Answer:

w = 25

Step-by-step explanation:

The function A(w) = -(w-25)² +625 is in vertex form. The vertex (maximum) is at (w, A) = (25, 625). A width of 25 meters will maximize the area.

Answer:

∛3, ∛3 to the fourth power, 3³∕ ², 3³∕ ², radical 3 to the fifth power

Step-by-step explanation:

I'm going to convert all these to decimal form to make it easier.

3³∕ ² = 4.5

∛3 = 1.44

radical 3 to the fifth power= 15.60

∛3 to the fourth power= 4.33

Solve 4 + 2 sinx= 14-8 sinx for 0° ≤ x ≤ 180
Oduvanchick [21]
<h2>Answer:</h2>

<u>x= 90°</u>.

<h2>Step-by-step explanation:</h2>

<h3>1. Write the expression.</h3>

4 + 2 sin(x)= 14-8 sin(x)

<h3>2. Subtract "4" from both sides of the equation.</h3>

-4+4 + 2 sin(x)= 14-8 sin(x)-4\\ \\2 sin(x)= 10-8 sin(x)

<h3>3. Add "8sin(x)" to both sides of the equation.</h3>

2 sin(x)+8 sin(x)= 10-8 sin(x)+8 sin(x)\\ \\10 sin(x)= 10

<h3>4. Divide both sides by 10.</h3>

\frac{10 sin(x)}{10} = \frac{10}{10} \\ \\sin(x)=1

<h3>5. Apply the arcsin of sin^-1 to both sides of the equation.</h3>

arcsin(sin(x))=arcsin(1)\\ \\x=90

<h3>6. Conclude.</h3>

<u>x= 90°</u>.

At basketball practice you made 21 out of 80 shots. Which choice is closest to the percentage of shots you made?
love history [14]
Since this is a percentage, all you have to do is divide 21 from 80 and multiply that by 100
 21/80 = .2625 * 100 is 26.25

The answer closest to this is 25%, so the answer is 25%

Hope this helped! :D
