Answer:
19.375 m.
Step-by-step explanation:
Before the first bounce it has travelled 10 meters.
Then after just hitting the ground the second time it has travelled 10 +1/2(10) = 15 m.
The common ratio is 0.5 and we want the sum of 5 terms
= a1 (1 - r^n) / (1 - r)
= 10 * (1 - 0.5^5) / (1 - 0.5)
= 19.375 m.
20. (a) a rectangle
(b) a circle
(c) triangle
22. volume = pi r^2 h
10 = pi r^2 * 2
r^2 = 10 / 2pi = 1,5915
r = 1.262
diameter = 2 *1.262 = 2.52 feet to the nearest hundredth Answer
Answer:
this is growth
Step-by-step explanation:
so it will have 500,000 approximately "t" years after 2015.
