All Real Numbers is the domain
1.Simplified each one
2/5 (both divided by 7) , 1/2 (divided by 21)
2.Make them into integer
(2/5 )*(2/2)=4/10 , (1/2)*(5/5)=5/10
Now the dominators are the same ,you can just compare the numerators. It is 4:5
Answer:
See below for answer
Step-by-step explanation:
The radius of the sphere is 5 inches. Correct?
Formula for the volume of a sphere is 4/3πr³
V = 4/3 · π · r³
V = 4/3 · π · 5³
V = 4/3 · π · 125
V = 4/3 · 125 · π
V = 500 /3 · π
V = 523.3 cubic inches Using π = 3.14
if using π on the calculator then V = 500/3 ·π = 523.6cubic inches
The first two rows of coefficients are identical, so by inspection, the determinant is 0.
