Answer:
7.8. 10 ^ 3 m / s
Step-by-step explanation:
The computation of the average speed in m/s is shown below:
The average speed equation is
= ΔS ÷ Δt;
As We know that
an entire revolution would be40,000 km
and a satellite takes 85 minutes to complete a revolution,
So,
ΔS = 40,000 km = 40,000,000 m
Δt = 85 min = 5 100 s
Now the average speed is
= 40 000 000 ÷ 5 ÷ 5 100
= 7843.14 m / s
= 7.8. 10 ^ 3 m / s
It depends but it's most like a A.
I'd say a 98/99% is an A+
Answer:
yes since it pass the vertical line test

Answer:
B
Step-by-step explanation:
Answers and justitication:
1) (7x)^3 + 8→ 8 added to the cube of 7x
becasue the cube of 7x is (7x)^3 and then 8 is added to it.
2) (7x + 8)^3 → the cube of the sum of 7x + 8
because first you add 8 to 7x and then the result is cubed.
3) 7x^3 + 8 → 8 added to 7 and x cubed.
4) 7(x+8)^3 → 7 times the cube of the sum of x and 8.
because first 8 is added to 8, then the result is cubed, and finally the result is multiplied by 7.
