24 - x = y
Step-by-step explanation:
one point goes on 22 while another goes on 24
Answer:
5/y^3
Step-by-step explanation:
We know the area of the middle rectangle is 48 (length * width). removing that rectangle leaves us with two semicircles. you can combine those semicircles to be the equivalent of one circle. the area for a circle is r^2 * pi. we know the diameter is 4 because that is where we cut the semicircles. radius is half the diameter, so r is 2. 2^2 is 4, 4* pi is 12.56. add 12.56 (area of semicircles) with 48 (area of rectangle) and we get 60.56
Answer:
The ballon will hit the ground after 1 s.
Step-by-step explanation:
In this case we want to solve for x, but were given a equation to the height of the ballon, we can organize it in a way that isolates x on the left side of the equation so it can be used to what we want. So we have:
h = -16x^2 +16
h + 16x^2 = 16
16x^2 = 16 - h
x^2 = (16 - h)/16
x = sqrt(16 - h)/sqrt(16) = sqrt(16 - h)/4
When the ballon hits the ground it's height is 0 feet, so we substitute that on our equation and we'll have the right answer.
x = sqrt(16 - 0)/4 = sqrt(16)/4 = 4/4 = 1 s
