The height above the surface of the Earth (in meters) of a rock thrown into the air at 10 m/s after x seconds is given by f(x)

Sonbull [250]

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.

6. Protein bars come in a 4-pack box or 12-pack

cricket20 [7]

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>

Which equation represents the relationship between the x-and y-values shown in the table.

Dmitrij [34]

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

Mary wants to fill in a cylinder vase.At the flower store they told her that the vase should be filled 3/4 for the flowers to la

borishaifa [10]

<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:

$=\frac{3}{4} *10=7.5$ inches

Then, find the volume of the water of this height:

$Volume = \pi *4^2*7.5 = 376.9$

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