Answer:
4400 ft/ minute
Step-by-step explanation:
Given data
speed = 50 mph
we want to convert the speed from mph (mile per hour) to feet per minute
1 mile = 5280 feet.
convert 50 miles to feet
=50*5280
=264000 feets
convert 1 hour to minute
= 60minutes
Hence the speed in feets per minute is
=264000/60
=4400 ft/ minute

Answer:
160 units.
Step-by-step explanation:
In order to find the minimum cost, we need to find the vertex of the equation since it is the lowest point of the graph. To find the vertex, we use the following equation.
x = -b/2a
In this equation, a is the coefficient of x^2 and b is the coefficient of x. So we plug in and solve.
x = -b/2a
x = -(-80)/2(.25)
x = 80/.5
x = 160
