Answer:
To find the surface area of a cube, use the formula: surface area = 6s^2, where s is the length of one of the sides. If you don't know the length of the sides, you can find the surface area using volume. Just find the cube root of the volume, which is equal to the length of one side of the cube.
Step-by-step explanation:
so in this case:
SA= 6(3)^2
= 18^2
= 324
Answer:
Step-by-step explanation:
-2(-1) + 7y = -54
2 + 7y = -54
-2 -2
7y = -56
Divide by 7
y = -8
Answer:
Is
Step-by-step explanation:
you can only see values of
Ranging from $-3$ to $3$ and they're included, so domain is $[-3,3]$
and $y$ values ranging from $-2$ to $4$ but $-2$ is not included so range is $(-2,4]$
Answer:
-189.8 J
Step-by-step explanation:
We are given that f
Force applied=F=35 Ni-37 Nj
Displacement, s=(-8.7m)i-(3.1m)j
We have to find the work done .
We know that
Work done=
Using the formula
Work done=
Work done=
Using 
Work done=-189.8J
Hence, the work done =-189.8 J
