Answer:
Rock travels about 8.2x²meters higher on the moon than on the Earth.
Step-by-step explanation:
Expression showing the height of a rock thrown into the air at Earth is,
f(x) = -9.8x² + 10x + 1.5
Similarly, expression showing the height of rock thrown on the moon is,
g(x) = -1.6x² + 10x + 1.5
Difference in the height of the rock thrown on moon = g(x) - f(x)
= (-1.6x² + 10x + 1.5) - ( -9.8x² + 10x + 1.5)
= -1.6x² + 9.8x² + 10x - 10x + 1.5 - 1.5
= 8.2x²
Therefore, rock travels about 8.2x²meters higher on the moon than on the Earth.
Answer:
f(0)=-2
Step-by-step explanation:
We are given that f(x)=3x-2
And we are asked to determine f(0)
In order to do so, we will replace x with 0 in our function
Hence
f(0) = 3(0)-2
f(0)=0-2
f(0)=-2
Answer:
- Deck's width is 6 feet.
- The area is 72 sq. ft.
Step-by-step explanation:
First, label it out:
- Length: 12 ft.
- Width: ?
- Area: ?
Then, we add up 12 twice (Since the length is on 2 sides):
- 12 + 12 = 24
- 36 - 24 = 12
- 12 - ? = ?
Now, we write down a 6 in the ?:
Width = 6.
We are not done!
Now, we have to solve for area.
