121 ounces you just do 7 times 16 and then add nine
Coordinates of R (4,10)
•————•————•
(?,?) (5,9) (6,8)
You have to see how the x & y changed from point M to S and do the same thing for point R to M
M S
(5,9) >>>> (6,8) (x+1, y-1)
R M
(4, 10) >>>> (5,9) (x+1, y-1)
4 * √ 64 = 32 inches
----------------
find the side with the inverse formula of the Area ( if A = l², l = √A), then multiply by 4, you find the perimeter and your answer
The height of the object at the time of launch is 100 meters.
To find this, we simply have to put 0 in for x, as this is when there has been no time (at launch)
h(x)=-5(x-4)^2+180
h(0)=-5(0-4)^2+180
h(0)=-5(-4)^2+180
h(0)=-5(16)+180
h(0)=-80+180
h(0) = 100
