C. Because you have to look for the greatest number. Disregard whether it is negative or positive. Since you are looking for steepness. That does not matter.
Answer:
120 minutes
Explanation:
The film starts at noon (12pm) and takes 120 minutes or 2 hours meaning it will stop and replay at 2:00pm. The documentary is 30 minuets meaning it will finish and replay again at 12:30, 1:00, 1:30 then at 2:00.
<u> case a)</u> The area of the square hole is 8 square centimeters
we know that
the area of a square is equal to
![A=b^{2}](https://tex.z-dn.net/?f=A%3Db%5E%7B2%7D)
where
b is the length side of the square
in this problem we have
![A=8\ cm^{2}](https://tex.z-dn.net/?f=A%3D8%5C%20cm%5E%7B2%7D)
<u>Find the length side b</u>
![b^{2} = 8 \\b= \sqrt{8} \ cm\\b= 2\sqrt{2} \ cm](https://tex.z-dn.net/?f=b%5E%7B2%7D%20%3D%208%20%5C%5Cb%3D%20%5Csqrt%7B8%7D%20%5C%20cm%5C%5Cb%3D%202%5Csqrt%7B2%7D%20%5C%20cm)
<u>the answer Part a) is</u>
the length side of the square is ![2\sqrt{2} \ cm](https://tex.z-dn.net/?f=2%5Csqrt%7B2%7D%20%5C%20cm)
Part b) The volume of a cube shaped block is 64 cubic centimeters
we know that
the volume of a cube is equal to
![V=b^{3}](https://tex.z-dn.net/?f=V%3Db%5E%7B3%7D)
where
b is the length side of the cube
in this problem we have
![V=64\ cm^{3}](https://tex.z-dn.net/?f=V%3D64%5C%20cm%5E%7B3%7D)
<u>Find the length side b</u>
![b^{3} = 64 \\b= \sqrt[3]{64} \\b= 4\ cm](https://tex.z-dn.net/?f=b%5E%7B3%7D%20%3D%2064%20%5C%5Cb%3D%20%5Csqrt%5B3%5D%7B64%7D%20%5C%5Cb%3D%204%5C%20cm)
therefore
<u>the answer Part b) is</u>
the length side of the cube is ![4\ cm](https://tex.z-dn.net/?f=4%5C%20cm)
We are given with the expression <span> B = 703 * w / h^2. To isolate w in the function, we multiply the whole equation by h^2. This results to B h^2 = 703 w. Next, we divide the equation by 703 to isolate w. The final expression of w becomes w = B h^2 / 703 </span>
