That is height
h=16t^2+16t+480
when h=0 is when it hits the water
0=16t^2+16t+480
undistribbute 16 for ease
0=16(t^2+t+30)
16*0=0 so assume
t^2+t+30=0
factor
(t+6)(t-5)=0
set to zero
t+6=0
minus 6
t=-6
false, since you cannot have negative time
t-5=0
add 5
t=5
at t=5 she hits the water
5 seconds
200 divided by 5 equals 40.
So therefore, 40 times 5 equals 200.
It depends, what does a mean? If you know just add what a means to 3 then subtract 4.
Step-by-step explanation:
..I have Solve the question in the pic.
Triangles have 3 vertices. The total is 21 vertices. 21 / 3 = 7. He drew 7 triangles.
