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:
The 12 pack has a better value.
Step-by-step explanation:
1. create a ratio table.
you want to know how much the 4 pack would cost if it was a 12 pack.
you can see the ratio table in the picture above.
As you can see, when the 4 pack equals $7.68, making it a 12 pack will equal $23.04.
<em>Then</em><em>,</em><em> </em><em>compare</em><em> </em><em>2</em><em>3</em><em>.</em><em>0</em><em>4</em><em> </em><em>to</em><em> </em><em>2</em><em>2</em><em>.</em><em>3</em><em>2</em><em>.</em><em> </em>
<u>In</u><u> </u><u>conclusion</u><u>,</u><u> </u><u>the</u><u> </u><u>1</u><u>2</u><u> </u><u>pack</u><u> </u><u>has</u><u> </u><u>a</u><u> </u><u>better</u><u> </u><u>value</u><u>.</u>
C. y = 3x - 4
Step-by-step explanation:
Given coordinates:
(2, 2), (3, 5), (5, 11), (7, 17)
The equation of any straight line is
y = mx + c
Where
m = Gradient
c = Constant
Gradient = y2 - y1/x2 - x1
Substitute any two values of y with the respective values of x.
Gradient = 17 - 2/7 - 2
= 15/5
= 3
Substitute the gradient into the general formula.
y = 3x + c
Substitute any value of the coordinate to the equation
2 = 3(2) + c
2 = 6 + c
c = -4
From y = mx + c,
substitute the values of m, the gradient, and c, the constant.
y = (3)x + (-4)
y = 3x - 4
<u>Answer:</u>
Approximately 377 cubic inches of water.
<u>Step-by-step explanation:</u>
We know that Mary wants to fill in a cylinder vase and she was told that the vase should be filled 3/4 for the flowers to last the longest. We are to find how much water should she pour into the vase.
So first, we will find the height of the water:
inches
Then, find the volume of the water of this height:

Therefore, Marry should pour approximately 377 cubic inches of water.
