Answer:
20
Step-by-step explanation:
F (-7) = -6x -22
F (-7) = -6 (-7) - 22
F (-7) = 42- 22
F (-7) = 20
hope that helps
Answer:
Sally's total commute was 75 minutes. (1 hour and 15 minutes)
Let's thing
949 ----- 100% of the price
499 ------ x% of the price
Multiply in cross
949.x = 100.499
949x = 49900
x = 49900/949
x = 52,58%
So, rounding it 52,58% ≈ 53%
Alternative B
Answer:
Step-by-step explanation:
17x > -17
x > -1
Answer:
Step-by-step explanation:
a.) the maximum is just the vertex
-35/(2*-4.9)= it takes 3.5714 seconds to hit the maximum
which in height is
-4.9*3.5714^2+35*3.5714 +1= 63.5 metres
b.) for this just plug in 2
-4.9*2^2+35*2+1= 51.4 metres
c.) just plug in f(0) =1 meter
d.) find the x intercepts (using the quadratic formula)
seconds
(there is another answer but it doesn't make sense in the context of this question)
