Answer:
- <u><em>Rounding to nearest tenth of centimeter, the ball bounces 192.1 cm high on the 5th bounce.</em></u>
<u><em></em></u>
Explanation:
The <em>ball is dropped from a height of 900 centimeters</em>.
Since the heights form a <em>geometric sequence,</em> you can find a common ratio between consecutive terms. This is:
- Height bounce 2 / height bounce 1 = 560 / 800 = 0.7
- Height bound 3 / height bounce 2 = 392 / 560 = 0.7
Hence, the ratio of the geometric sequence is 0.7, and taking bounce 1 as the start of the sequence, the general term of the sequence is:
With that formula you can find any term:
Rounding to <em>nearest tenth of centimeter</em>, the ball bounces 192.1 cm high on the 5th bounce.
Answer:
I think that is a function
Step-by-step explanation:
Answer:
There is no graph
Step-by-step explanation:
One has to solve this using either substitution or elimination then...
x + y = 5
–2x + y = –4
x + y = 5
2x –y = 4
3x = 9
x = 3
y = 2
Solution (3 , 2)
Expression for surface area is 3.14(6 * 4 + 6^2) = 3.14(24 + 36)
surface area is 3.14(60) = 188.4 square units.
