When the object reaches the ground, the height is zero, so:
0 = 144 - 16t^2
then you just solve for t, so subtract the 144 over
-144 = -16t^2
then divide by the -16
9 = t^2
then take the square root of both sides
3 = t
therefore, it will take three seconds for the object to reach the ground.
You need the total amount of how many animals
5, 10, 30, 60, 180, 360, 1,080
5*2=10
10*3=30
30*2=60
60*3=180
180*2=360
360*3=1,080
13 is the answer because you times 2 and -5 that's -10 and then you subtract -3 and that -13 and the absolute symbols change it to positive 13
Assuming the function is x^2
let y = x^2
interchange x and y
x = y^2
y = sqrt x
so,
sqrt x is the inverse of x^2.
