Answer:
y = -3x + 12/2
Step-by-step explanation:
Step 1: Add -x to both sides
x + 2/3 + -x = 4 + -x
2/3y = -x + 4
Step 2: Divide both sides by 2/3
2/3y ÷ 2/3 = -x + 4 ÷ 2/3
y = -3x + 12/2
Given that the height of the ball has been modeled by h=120t-16t^2, the reasonable range will be found as follows:
maximum height is attained when h'(t)=0
given h=120t-16t^2
h'(t)=120-32t=0
thus solving for t, we get:
t=3.75 sec
thus the maximum time attained will be:
120(3.75)-16(3.75)^2=225 ft
Therefore the reasonable range will be [0≤h(t)≤225]
Answer:
The volume of the rectangular prism is
Step-by-step explanation:
In order to solve this problem, you must multiply the dimensions by each other. Since the area has been calculated, multiply the height by the area.

Answer: $139.89
————————————————
1st: Convert ft to yd
1 foot = 0.3 yards
So 1/0.3 = 15/x —> x = 5 yards
————————————————
2nd:
So 28 yards = 84 feet
15ft/$24.98 = 84ft/x
(24.98)(84) = 15(x)
139.89 = x
