The relationship iof the ostrich running at 43 miles per hour is proportional.
<h3>Speed of the ostrich</h3>
Since speed = distance per unit time
The speed of the ostrich is 43 miles per hour. This means that the ostrich covers a distance of 43 miles every hour.
Since the ostrich always covers a distance of 43 miles every hour, we see that distance is proportional to time.
So, the relationship iof the ostrich running at 43 miles per hour is proportional.

Answer:
We get t= 7.22 and t=0.28
The correct options are Option A and Option G
Step-by-step explanation:
The height h of toy rocket at time t seconds after launch is given by the equation 
We need to find how many seconds until the rocket is 40 feet?
We are given height of rocket h(t) = 40 feet
and we need to find time t
Using the equation
we can find time t
We have h(t)=40

Now, we will solve the quadratic equation using quadratic formula: 
We have a =16, b=-120 and c=32
Putting values and finding t

So, we get t= 7.22 and t=0.28
The correct options are Option A and Option G
