The nearest tenth of how fast a rover will hit Mars' surface after a bounce of 15 ft in height is 20.7ft/s.
<h3>What is the approximation about?</h3>
From the question:
Mars: F(x) = 2/3
Therefore, If x = 15
Then:
f (15) = 2/3
= 16/3
= 20.7ft/s
Hence, The nearest tenth of how fast a rover will hit Mars' surface after a bounce of 15 ft in height is 20.7ft/s.

Fred's frog . . . 7 times
Al's frog . . . . . 1 time
Total for both frogs = 8 times = 56 inches
Divide each side by 8 : 1 time = 7 inches
Fred's frog . . . 7 times = (7 x 7) = <em>49 inches</em>
My frog . . . 1 time = 7 inches
If an item has been discounted 30%, then it is currently worth 70% of the original price. This tells us that $49 is 70% of the original price. Therefore, you need to divide $49 by 70% to get your answer (you have to work backwards; remember that you would have multiplied the original number by 0.7 to get 49):
49÷(70/100)= $70
Therefore, the price of the original product was $70
The formula for the volume of a sphere is (4/3)*pi*r^3. Using this formula, we have 44.6022 cm^3 = (4/3)*pi*r^3. Solving for r, we get 2.2 cm. Thus, the radius of the sphere with an approximate volume of 44.6022 cubic centimeters is 2.2 cm. To add, the volume of a sphere is also exactly two-thirds the volume of its circumscribed cylinder.
