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 answer is 51 remainder 4 because 51* 4 =408 and 412 + 4 = 412

I find it easiest to right down the numbers as I read the question,
(9+10-4) x3 +7-2
Answer:
He did the complete opposite of what he needed to do
Step-by-step explanation:
The error is that when you need to find x - intercept, you need to replace the value of y with zero, not the y value.
Cause otherwise, what he did here is to find the y - intercept
