Take the equation <span> h (t) = 73 – 16 t^2 and plugin 9 for h(t) and then solve for t like the following:
</span>9 = 73 - 16 t^2
9 - 73 = 73-73 - 16t^2
-64 = -16t^2
-64 / -16 = -16t^2 / -16
4 = t^2
Now square both sides of 4 = t^2
2 = t
t = 2
Answer = 2 seconds
</span>9 = 73 - 16 t^2
9 - 73 = 73-73 - 16t^2
-64 = -16t^2
-64 / -16 = -16t^2 / -16
4 = t^2
Now square both sides of 4 = t^2
2 = t
t = 2

Answer:
The solution is r=40.
Step-by-step explanation:
First, we identify the parts of the division:
"r" is the dividend of the division.
10 is the divisor
4 is the quotient.
To get the value of "r", we have to make a tape diagram where the divisor represents the number of equal-sized parts (boxes) and the quotient represents de quantity inside the boxes.
The tape diagram is made of 10 equal-sized parts of 4.
So the result is 10×4=40. The value of "r" is 40.
