The hardest math problem is solving life, I mean this because everyone is trying to make good decisions which means you never stop thinking through your whole day
Answer:
(3×-2^3×5^-2)^2
Step-by-step explanation:
I think this is it I'm not sure sorry if it's not I tried my best to help you.
The relevant formula that we can use in this situation is:
v = v0 + at
where v is the final velocity, v0 is the initial velocity
= 20 km/hr, a is acceleration at 3.4 m/s^2 and t is time at 20 seconds
First convert v0 to m/s, v0 = 5.56 m/s
v = 5.56 m/s + 3.4 m/s^2 * 20 s
v = 73.56 m/s
Then convert back to km/hr:
<span>v = 264.82 km/hr</span>
Answer:
D. 720cm squared is the answer
Correct answer would be D. hope this helps :)
