Answer:
1.548 gallons
Step-by-step explanation:
Length of the rectangular wall = 25.1 ft.
Width of the rectangular wall = 18.5 ft.
Area of the rectangular wall = length * width = 25.1 * 18.5
= 464.35 square feet
300 square feet wall can be painted using 1 gallon of paint.
=> 1 square feet wall can be painted using ![\[\frac{1}{300}\]](https://tex.z-dn.net/?f=%5C%5B%5Cfrac%7B1%7D%7B300%7D%5C%5D)
gallon of paint.
=> 464.35 square feet wall can be painted using ![\[\frac{1}{300} * 464.35\]](https://tex.z-dn.net/?f=%5C%5B%5Cfrac%7B1%7D%7B300%7D%20%2A%20464.35%5C%5D)
gallon of paint.
= 1.548 gallons of paint
Answer:
54.5
Step-by-step explanation:
H=+15 m
v=+5 m/s
Ball hits the ground when h(t)=-15m
h(t)=-9.8t^2+vt+h
=>
-15=-9.8t^2+5t+15
9.8t^2-5t-30=0
Solve for t, using quadratic formula,
t=-1.513 or t=2.023
reject negative root due to context, so
t=2.023 seconds
2)
h(t)=-16t^2+20t+8
a. height before pitch is when t=0, or h(0)=8
b. highest point reached when h'(t)=-32t+20=0 => t=5/8 seconds
c. highest point is t(5/8)=-16(5/8)^2+20(5/8)+8=47/5=9.4 m
d. ball hits ground when h(t)=0 => solve t for h(t)=0
=> t=-0.3187 seconds or t=1.569 seconds.
Reject negative root to give
time to hit ground = 1.569 since ball was pitched.
