f ( 7 ) = 2.4 ft

Step-by-step explanation:

Solution:-

- This is modeled using a geometric sequence function with initial height from which ball is dropped hi = 18 feet, and a decrease in height by 25% after each successive bounce :

                      f ( x ) = 18 (0.75)^x

Where,   x e [ 0 , ∞ ) : The number of bounces.

             f (x) : The maximum height after xth bounce.

- The maximum height reached by the ball after its 7th bounce. So, x = 7:

                       f ( 7 ) = 18 (0.75)^7

                       f ( 7 ) = 2.4027 ft

- To the nearest tenth:

                     f ( 7 ) = 2.4 ft

Please answer a through d
Elza [17]

Answer:

See explanation below.

Step-by-step explanation:

Given: 100 lbs on Earth is 16.6 lbs on the moon.

a. The independent variable is weight. The gravity of the Moon and the gravity of the Earth are constant. Weight can change, but gravity is a constant.

b. An equation that relates the weight of someone on the Moon who travels to the Earth:

100 / 16.6 = 6.02. Take the Moon weight and multiply by 6.02:

Moon Weight * 6.02 = Earth Weight.

Proof:

16.6 * 6.024 = 99.99 - approximately 100 lbs Earth weight.

c. A 185 lb astronaut on Earth would weigh:

16.6 / 100 = .166. Take the Earth weight and multiply by .166:

185 * .166 = 30 lbs on the Moon.

d. A person who weighs 50 lbs on the Moon:

50 * 6.024 = 301.2 lbs on Earth.

Hope this helps! Have a good day and year! :)

C) P, Q, and R are prime numbers such that<br> 3 * P + 7 * Q + 15 * R = 102.<br> What is Q?
lana66690 [7]

Answer:

Q = 3

Step-by-step explanation:

3 * P + 7 * Q + 15 * R = 102

7Q = 102 - 3P - 15R

Q = (102 - 3P - 15R)/7

Try P = 2; R = 3

Q = 51/7 not an integer

Try P = 2; R = 5

Q = 21/7 = 3

Solution: P = 2; Q = 3; R = 5

Answer: Q = 3
