Tina throws a baseball straight up from a height of 3 feet and at a speed of 50 feet per second. The height of the ball in feet
vodka [1.7K]

Answer:

9 feet

Step-by-step explanation:

The height of the ball in feet is given by the polynomial:

h(t) = -16t^2+50t+3

where t is the time in seconds.

After 3 seconds, t = 3:

h(3) = -16(3)^2 + 50(3) + 3 \\\\h = -144 + 150 + 3 = 9 feet

The height of the ball after 3 seconds is 9 feet.

So the graph shows the cost of the phone call on the y-axis and the length of the phone call on the x-axis.
The question ask is what is the least expensive per minute.
So your equation is cost/time.
Then you plug in the values of each point.
w=$1.25/2 minutes
x=$2/5 minutes
y=$2/10 minutes
z=$2.50/10.5 minutes
Solve each question-
w=0.63 (rounded)
x=0.4
y= 0.2
z=0.24 (rounded)
These values show the cost per minute of each point. So, in order the answer the question which one cost the least per minute you would select the lowest value answer from the question of each point. Which would be y.
