-7+15. this is what i think it is.
So first you'll substitute x for -2.3 then you'll subtract 2 by 1 which equals 1 then you'll divide -2.3 on both sides which will equal g = -1.3
What does part a mean i dont understand
Answer:
x - 4 = 4x
4x × 5 = 20x
20x + 9 = 29x
Step-by-step explanation:
Answer:
1) 102.7 meters
2) 11
Step-by-step explanation:
1) -4.9x² + 75x = -4.9x² + 50x + 38
25x = 38
x = 1.52 s
Height = -4.9(1.52)² + 75(1.52) = 102.67904 m = 102.7 m
2) f(x) = x² + 3x - 2
f(2) = 2² + 3(2) - 2 = 8
f(6) = 6² + 3(6) - 2 = 52
Average rate of change:
(52-8)/(6-2) = 11
