So we need to find the sum of the first 5 terms.
You have told me that the first term is 10 meters, and that r = 0.5 per term.
With this knowledge, we can use the formula s_n=a₁((1-r^n)/(1-r)).
Plugging in the terms that we know...
s₅=10((1-0.5⁵)/(1-0.5))
s₅=10(0.96875/0.5)
s₅=10(1.9375)
s₅=19.375
With s₅, we can determine that the ball has traveled a total of 19.375 meters after 5 bounces.
The second question is the first choice
The first part is 8 x 40=320
8 x 7=56
320+56 and i am not sure what you have going on on the other half
Answer:
I think it's 150
Step-by-step explanation:
(8+7) × 10 = 150
Answer:
513.24132
Step-by-step explanation:
None of the numbers are large enough to make the next number higher. Therefore that would just be your answer.
