Answer:
answer C
Step-by-step explanation:
I had the same test question
U= 9.4m/s
v= -7.4m/s (Negative sign because it is in the opposite direction as he is rolling back)
t= ?
s= ?
a= ?
Now, a= v-u/t
= -7.4-9.4÷3
=-5.6
By the second equation of motion.
s= ut+1÷2at*2 ( *2 is the power)
s= 9.4×3+1÷2×-5.6×3*2
= 28.2 +(-25.2)
=3
Therefore s or the distance travelled is 3m.
Well, sum means adding. So adding it all together, I got 2.83 with the 3 repeating
I believe it python idk any but due to my research i think it python
<u>Answer:</u>
The correct answer option is d. 9.
<u>Step-by-step explanation:</u>
We are given an expression
and we are supposed to simplify it.
We can also write
as
.
We know the power rule
which means that to raise a power to a power you need to multiply the exponents.
So multiplying the exponents to get:
![(3^3)^{\frac{2}{3} }\\3^{3.\frac{2}{3}](https://tex.z-dn.net/?f=%283%5E3%29%5E%7B%5Cfrac%7B2%7D%7B3%7D%20%7D%5C%5C3%5E%7B3.%5Cfrac%7B2%7D%7B3%7D)
3 gets cancelled by 3 so we are left with:
![=9](https://tex.z-dn.net/?f=%3D9)
Therefore, the correct answer option is d. 9.
