Answer:
3.4
Step-by-step explanation:
(−9 + 6.8 − 1.2) · (−0.49 − 0.51)
(−3.4) · (−1)
3.4
Answer:
4: A
Step-by-step explanation:
Mathematically, the average speed over a particular range will be;
f’(b)-f’(a)/(a-b)
In this case; a = 2 and b = 10
So we have the following;
f’(x) = 4t + 1
f’(10) = 4(10) + 1 = 41
f’(2) = 4(2) + 1 = 9
So we have the average speed change as;
(41-9)/(10-2)
= 32/8 = 4
Answer:
4
Step-by-step explanation:
3, 4, 4, 5, 6
<span>The right answers would be B (7 miles after marker 58)
and C (7 miles before marker 58). The problem doesn't say if the rest area is going to be built 7 miles before milepost 58 or 7 miles after it.</span>
Answer:
A.96.25 steps. B. Approximately 37 steps shorter
Step-by-step explanation:
From Pythagoras theory,
Hyp² = Adj² + Opp²
Hyp² = 52² + 81²
Hyp² = 2704 + 6561
Hyp² = 9265
Hyp = √9265
Hyp = 96.25 steps
= 81 + 52 = 133 - 96.25
= 36.75 or approximately 37 steps shorter
