Answer:

Option D is the correct answer.

Step-by-step explanation:

Initial height = 4 feet

Given that the height of the tree increased by a constant amount each year for the next 6 years. At the end of the 6th year, the tree was 1/5th taller than it was at the end of the 4th year.

Let the rate of growing each year be g.

After 6 years height of tree = 4 + 6g

After 4 years height of tree = 4 + 4g

At the end of the 6th year, the tree was 1/5th taller than it was at the end of the 4th year.

That is

                4+6g=4+4g+\frac{4+4g}{5}\\\\4+6g=\frac{20+20g+4+4g}{5}\\\\20+30g=24+24g\\\\6g=4\\\\g=\frac{2}{3}ft/year

Option D is the correct answer.

Answer:

B

Step-by-step explanation:

To find the constant of proportionality between y and x, divide  \frac{y}{x} for all given values of the chart. If you get the same number, then that is the constant. If they are all different numbers, then one does not exist for that function.

Using the method above, you should get:

Chart A = 2/5

Chart B = 1/5 (Correct Answer!)

Chart C = N/A

Hope this helps!

The formula for potential energy is P = mgh. Solve the equation for h.
Liono4ka [1.6K]

Answer:

P = mgh

P/mg = h

We can divide both sides by mg, since both mass and gravity are being multiplied and not added.

Hope this helps!! :)
