2. The volume of a cube is



The volume is 91.125 m^3
Answer: Slope: -1 Y-intercept: -4
Step-by-step explanation:
Slope formula:

m = -1
When you draw this on the graph, the y-intercept is -4.
y = -4
Answer:
3i-1
Step-by-step explanation:
2+3i-3
3i-1
Let the required point be (a,b)
The distance of (a,b) from (7,-2) is
= 
But this distance needs to be betweem 50 & 60
So

Squaring all sides
2500 < (a-7)² + (b+2)² < 3600
Let a = 7
So we have
2500 < (b+2)² <3600
b+2 < 60 or b+2 > -60 => b <58 or b > -62
Also
b+2 >50 or b + 2 < -50 => b >48 or B < -52
Let us take one value of b < 58 say b = 50
So now we have the point as (7, 50)
The other point is (7,-2)
Distance between them
= 
This is between 50 & 60
Hence one point which has a distance between 50 & 60 from the point (7,-2) is (7, 50)
