robert is in charge of the community swimming pool. each spring he drains is in order to clean it. then he refills the pool, whi
Airida [17]
If the required rate is gallons per minute, then its obvious from the question, that the rate of filling the pool is 10 gallons per minute, and its obviously a constant number. 
But for the rate to be in gallons per hour, then 
1 minute corresponds to 10 gallons
so 
1 hour corresponds to 10x60 = 600 gallons
hence
rate (gallons per hour) = 120,000/600 =  200 gallons per hour. 
which is again a constant number.

Find the function value of cos^2 (7pi/8)
Dima020 [189]
Mhm, absolutely. Notice that we do not have a common unit circle value for any division of 8. But we do have a value for is 7pi/4. Now in order to actually get the value of 7pi/8, we use a half angle formula. So what we do is we will write out the formula and plug 7pi/4 into that formula, this will give us the value of 7pi/8. So the formula we need to plug 7pi/4 into is this: <span>±<span><span><span>1+cos2θ</span>2</span><span>−−−−−−−−−</span>√</span></span><span>SO if you plug in 7pi/4 for theta in that formula, you think you could simplify it to find 7pi/8?</span>

\dfrac{4}{26}  \times  \dfrac{13}{20}

-------------------------------------
Divide by factor of 4.
-------------------------------------
<em>*Or divide by the factor of 2 twice</em>

\dfrac{1 \times 4}{26}  \times  \dfrac{13}{5 \times 4}

\dfrac{1}{26}  \times  \dfrac{13}{5}

-------------------------------------
Divide by factor of 13.
-------------------------------------

\dfrac{1}{2 \times 13}  \times \ \dfrac{1 \times 13}{5}

\dfrac{1}{2}  \times  \dfrac{1 }{5}

-------------------------------------
Combine into single fraction.

Answer:

Step-by-step explanation:

A triangular prism has three rectangular sides and two triangular faces. To find the area of the rectangular sides, use the formula A = lw, where A = area, l = length, and h = height. To find the area of the triangular faces, use the formula A = 1/2bh, where A = area, b = base, and h = height hope this helped somehow ;-; sry if not

Need Help please answer
djverab [1.8K]
For the 2nd part of 2. just plug in what you have for G in your previous graph into the equation. This will give you H for all 5 columns . Like 3×8(-1+5)= h = 3× 32= 96 so H should equal 96 and so on as far as this function.

For number 3. The equation is given so just plug in your T for time which is 3 seconds, so...-16(3)^2+90(3) = H the height at 3 seconds. I'm doing it in my head but should be the height is 414. You should also say whether it's ft or inches etc because the teacher or yourself left that out of the equation which is also vital lol.
