To solve this problem you must apply the proccedure shown below:
1. You must use the formula for calculate the volume of a sphere and the formula for calculate the surface area of a sphere, which are:
Where 
is the radius (
)
2. The volume is:
3. The surface are is:
The answer are: The volume is 
and the surface area is 
2 (x+2)/(x-10) is the simplified answer
Answer:
Δy = 5 Δx = 1
slope = 
= 5
Step-by-step explanation:
Answer: -0.95
Step-by-step explanation:
The value that explains the least-squares regression line is 90% or 0.9, and is also r^2.
You would just square root r^2 and get r=0.948. since the relationship is negative, r= -0.948, or -0.95
These are similar because they are both the same type of triangle (acute), but one is just dilated to a smaller degree than more than the other.
Let me know if this helps! <3
