Option B:
General formula for the height(feet) of a projectile over time:
where h represents height (feet)
t represents time
represents initial velocity
represents initial height(feet)
General formula for the height(metres) of a projectile over time:
where h represents height (feet)
t represents time
represents initial velocity
represents initial height(metres)
<u>Given data in the question:</u>
metre
m/s
To determine the equation to find time:
Substitute and in general formula for the height(metres) of a projectile over time:
Therefore option B is the correct answer.

Answer:
f(1)= 12-31+7
Step-by-step explanation:
f(1) = -12
Answer:
f(3)=5
f(0)= -7
Step-by-step explanation:
replace
4(3)-7
f(3)=5
f(0)=4(0)-7
f(0)=0-7
f(0)= -7
The house with 30000 cubic foot costs less to cool per cubic foot than the house with 25000 cubic foot.
Step-by-step explanation:
The cost of cooling 30000 cubic foot house = $7
Cost per cubic foot = 7/30000
=$0.00023
The cost of cooling 25000 cubic foot house= $6.50
Cost per cubic foot=6.50/25000
= $0.00026
The house with 30000 cubic foot costs less to cool per cubic foot than the house with 25000 cubic foot.
