Answer:
x
3
Step-by-step explanation:
You add 5 to both sides. Then divide it by 4 to get your answer.
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
Answer: 16*pi
Step-by-step explanation: The equation for diameter is pi*diameter. Since you already know the diameter, just plug it in.
Answer:
175 hope this helps
Step-by-step explanation:
Add 72 and 113
then subtract that from 360
Ok. So, say you have 1 whole. If you take half of that it would be 50% or 0.50 of the whole. So with 1.34 you can turn it into 1 and 0.34. You have one whole, so that is 100 percent. You than add the 34 hundredths which is 34 percent. So you have 134%. Do you understand all that?
