-6. because -6 is farther away from 0 than -5
Sub y = 0 in to find x intercept and x = 0 in to find y intercept
Answer:
Because square root is essentially the same thing as the power to a half
sqrt(x) is the same as (x)^1/2
By definition, the speed is given by the quotient between the distance traveled and the time it takes to travel that distance. We have then that the expression for speed is as follows
v = d / t
where
d: distance
t: time
Substituting
v = (90feet) / (5s) = 18feets / s
answer
the average rate of the airplane model, in feet per second was 18feets / s
