Answer:
b
Step-by-step explanation:
20 + 30 + 25 + 15 + 25 = 115
115 / 5 = 23
20 - 23 = |-3|
30 - 23 = 7
25 - 23 = 2
15 - 23 = |-8|
25 - 23 = 2
3 + 7 + 2 + 8 + 2 = 22
22/5 = 4.4
Answer:
A
Step-by-step explanation:
-5 y^ - I5 y=0
-5 y (y +3) =0
The question GIVES us an equation:
V₀ = √(v² - 64h) .
It TELLS us that v should be 100 ft/sec and h is 150 ft.
All we have to do is plug the numbers into the equation,
and then do the arithmetic to find V₀.
There's not even any Physics to do. Only arithmetic.
V₀ = √(v² - 64h)
v = 100
h = 150
V₀ = √(100² - 64·150)
V₀ = √(10,000 - 9,600)
V₀ = √400
V₀ = 20 ft per sec .
I'd use synthetic div. here, with 2 as my divisor:

1 -9 0
Note that the coefficients of the missing factor are given here and are 1 and -9. Thus, (x-9) is the missing factor.
