Answer:
0.3125
Step-by-step explanation:
If it decreases by 50% each time it hits the ground then all you have to do is divide 10 by 2 (50%) each time it bounces.
10 / 2 = 5 (first bounce)
5 / 2 = 2.5 (second bounce)
2.5 / 2 = 1.25 (third bounce)
Ect. . .
Until on the fifth bounce it is 0.3125m high.
Ok so to find the ratio just do 12/16 = 3/4. that's your common ratio.
The formula for sum of infinite :
a / (1 - r)
a is the first term and r is the ratio
which is
16 / (1 - (3/4))
which is
16 / (1/4)
16 * 4
which is 64
Answer:
6 to the second is 36 and 2 to the second is 4
Step-by-step explanation:
Both of those combined would equal 40. Are you looking for the algebraic expression, or is this good enough? Let me know! Bya!
