Answer:
Domain = (-∞,∞) { x|x∈R}
Range = { -4 , ∞} , { y|y≥-4}
Step-by-step explanation:
Answer:
B is the right answer
Step-by-step explanation:
The difference between the volume of a sphere and a cylinder is 2/3
take 30 x 2 = 60
60/3 = 20
The Volume of the Sphere is 20 m ^3
Hope this helps.
AD = AB
AD = 2r+8
AB = 5r-13
we need to find the value of r to find the total length
so 2r+8 = 5r-13
subtract 2r from each side:
8 = 3r -13
add 13 to each side:
21 = 3r
divide both sides by 3
r = 21 / 3 = 7
r=7
now we know r, so replace r with 7 in the equation for AD
AD = 2r+8 = 2(7) +8 = 14 +8 = 22
the answer is D. 22
