Answer:
A
Step-by-step explanation:
The surface area (A) of a sphere is calculated as
A = 4πr² ← r is the radius
here r = 2, hence
A = 4π × 2² = 4π × 4 = 16π units² → A
Step-by-step explanation:
A sequence is an ordered list of numbers.
lim n → ∞ an = 8 means that as n approaches infinity (becomes large), an approaches 8.
lim n → ∞ an = ∞ means that as n approaches infinity (becomes large), an approaches infinity (becomes large).
I think B is the only polynomial because A and C both have roots that aren't supposed to be in polynomial expressions and you can't divide (D)
Solving 4=2x is using the division property because in order to get the last portion of that answer u have to divide both sides by 2x to get x by itself
For example
4=2x to get x by itself you have to divide both sides by 2x
And your final answer would be
x is equal to 2 (x=2)
