Answer:
12
Step-by-step explanation:
Answer:
V = 1/3 • π • radius cubed • height
If the volume is is 16π and the height is 3, then 16π = 1/3 • π • r cubed • 3
16π ÷ (1/3 • π • 3) = 16
radius squared = 16 √16 = 4, so radius = 4
You can also check: 1/3 • r cubed • 3 = 16 The only value left to multiply is π
Step-by-step explanation:
Answer:
(negative infinity, 6)
Step-by-step explanation:
To get this:
1. -4x > 24
Divide by -4
2. x < 6
When you divide by a negative you have to flip the inequality. Therefore, any number that is less than 6 is the answer.
Answer:
A is a function.
Step-by-step explanation:
All the others are one-to-many relations.
For example in B, 3 maps to 10 and also maps to 30 ( one - to - many).
A function is a one-to-one or many-to-one mapping.
