Help would be appreciated :)

a rock is dropped from a height of 100 feet. Calculate the time between when the rock was dropped and when it landed. if we choose down as positive and ignore air friction, the function is h(t)= 36t^2-64

Hello, thx for any help!

Let R be the circle centered at (0,0) with radius 10. The lines x=6 and y=5 divide R into four regions R1, R2, R3 , and R4. Let R_i denote the area of region R_i If R1>R2>R3>R4,
then find R1-R2-R3+R4 mehr ..

As far as I figured, It looks like you squared to get. That is indeed the area of X'Y'Z', but the problem asks for the region that is contained in both. I think this is true but, not sure what to do?

Hi Macabrasubwoofer!

I think the answer to the first question is A, strong negative because we see a correlation of downwards sloping.

I also believe that the answer to the second question is D, no correlation. This is because they do not follow any sort of support/line, rather, they are all scattered.

Hope this helped!
