Answers
The time it take riders to pass over the hill and reach ground level is 111.19seconds
Functions and valuesGiven the roller coaster's height expressed by the function below;
h = -0.067t^2 + 7t + 50
where
t is the time in seconds
The driver will hit the ground at the point where h = 0
Substitute
-0.067t^2 + 7t + 50 = 0
Multiply through by -1
0.067t^2 - 7t +-50 = 0
Factorize
On factorizing, the positive value of "t" is 111.19 seconds

Answer:
D) 111.19
Step-by-step explanation:
Step 1:
set h = 0
0 = -0.067t^2 + 7t + 50
Step 2:
multiply by -1
0 = 0.067t^2 - 7t - 50
Step 3:
My way may differ than your way but my is plug in all answer choices as t. If the answer choice equal to 0 meaning the answer.
A choice
0 = 0.067(13.40)^2 - 7(13.40) - 50
0 = 12.03 - 94.5 -50
0 = - 132.47
It doesn't equal to 0 meaning this choice is wrong answer
B choice
0 = 0.067(50.07)^2 - 7(50.07) - 50
0 = 167.96 - 350.49 - 50
0 = - 232.53
It doesn't equal to 0 meaning this choice is wrong answer
C choice
0 = 0.067(52.24)^2 - 7(52.24) - 50
0 = 182.84 - 365.68 - 50
0 = - 232.84
It doesn't equal to 0 meaning this choice is wrong answer
D choice
0 = 0.067(111.19)^2 - 7(111.19) - 50
0 = 828.33 - 778.33 - 50
0 = 0

a circular wall clock with a circumference of 94.2 cm is mounted on a wall. How much area of the wall did it occupy
Answers
So…
94.2 = 3.14 • diameter
94.2/3.14 = 30 cm
The diameter is 30 cm, so the radius (1/2 of diameter) would be 15 cm.
Area = 3.14 • radius^2
So…
Area = 3.14 • 15^2
Area = 706.5 cm squared

Kevin is an auto mechanic. He spends 3 hours when he replaces the shocks on a car and 2 hours when he replaces the brakes. He works no more than 36 hours a week. He routinely completes at least 2 shocks replacements and 3 brake replacements a week. If he charges $400 for labor replacing shocks and $200 in labor for replacing brakes, how many jobs of each type should he complete a week to maximize his income?
Answers
Answer:
See below ....question is a bit unclear
Step-by-step explanation:
He makes 133.33 per hour with shocks and only 100 per hour with brakes.
he should only do 36/3 = 12 shock jobs per week and no brakes.
if he HAS to do at LEAST 3 brake jobs
then he should do 3 brakes and 10 shocks
The volume of a tree stump can be modeled by considering it as a right cylinder. Justin measures its circumference as 84 in and its volume as 20214 cubic inches. Find the height of the stump in feet. Round your answer to the nearest tenth if necessary.
Answers
The height of the stump tree which can be modeled by considering it as a right cylinder is 35.9 inches.
What is a cylinder?A cylinder is simply a 3-dimensional shape having two parallel circular bases joined by a curved surface.
The volume of a cylinder is expressed as;
V = π × r² × h
Where r is radius of the circular base, h is height and π is constant pi ( π = 3.14 )
Since the base of a cylinder is circular in shape, the circumference is expressed as;
C = 2πr
Given that the circumference of the base is 84 in, we can now calculate the radius r.
C = 2πr
84in = 2 × 3.14 × r
84in = 6.28 × r
r = 84in / 6.28
r = 13.4in
Now, the Radius of the cylinder r = 13.4in and its volume = 20214in³, we substitute this values into the expression for volume of cylinder above to find the height h.
V = π × r² × h
20214in³ = 3.14 × ( 13.4in)² × h
20214in³ = 3.14 × 179.56in² × h
20214in³ = 563.8in² × h
h = 20214in³ / 563.8in²
h = 35.9in
Therefore, the height of the stump tree which can be modeled by considering it as a right cylinder is 35.9 inches.

Find the volume of the triangular prism to the right.
5 ft
10 ft
The volume of the prism is ? ft^3
Answers
Answer:
rectangular is 114ft and triangular is 112ft
Step-by-step explanation:
Let the volume of a rectangular prism be VR and that of right triangular prism be VT. If The volume of the rectangular prism is 32 cubic feet more than the volume of the right triangular prism, then VR = 32 + VT
Since VR = length * width and height
VR = 6*x*3
VR = 18x ft³
Also VT = Length *width * Height/2
VT = (7 * x * 4)/2
VT = 28x/2
VT = 14xft³
Since VR = 32 + VT
18x = 32+(14x)
collect like terms
18x-14x = 32
4x = 32
divide both sides by 4
4x/4 = 32/4
x = 8
Volume of the rectangular prism = 18x
Volume of the rectangular prism = 18*8
Volume of the rectangular prism = 144ft³
Volume of the right triangular prism = 14x
Volume of the rectangular prism = 14*8
Volume of the rectangular prism = 112ft³
