Hello! Lets solve this :)
So for the first question :
h(t) = -16t^2 + 150
h(0)= -16 (0)^2 + 150
h(0)= -16(0) + 150
h(0)= 0 + 150
h(0)= 150 feet
Second question
We need to find here the time when the ball hit the ground; or when the height h(t) is 0.
In equation form
h(t) --> 0=16t^2 + 150
16t^2 = 150
t^2=150/16
t= <span>√150/16
t= 5</span><span>√6/4
t= 5 (2.45)/4
t= 3.06 seconds
</span>
Hope this helps! If you have any other questions or would like further explanation just let me know! :)
Answer:
Step-by-step explanation:
Cost price (CP) = Purchase amount + amount spend on repairing

Answer:
There are 15 girls
Step-by-step explanation:
Given:- Ratio of boys to girls = 5:3
And, the number of boys = 75
let the girls be 5x and boys be 3x
so, 5 × 75 { given }
x = 75/5 = 15
6x= 6 × 15 = 90
6x/6 = 90/6 = 15
