Ok to start this problem you must list two numbers that add to 14
7 and 7
9 and 5
10 and 4
6 and 8
those are the numbers that we will use for now..
Now multiply each pair of numbers and see which one equals 45
7 * 7 = 49, no
9 * 5 = 45, YES
10 * 4 = 40, No
6 * 8 = 48, No
The numbers discovered are 9 and 5
Triangle? If so I don’t know
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.
A because it’s 3/4 away from the middle & up 2 so it’s gonna be half
