In a geometric progression:
a, b, c, d...
The common ratio can be obtained using:
b/a = c/b = d/c
b/a = 112 / 64 = 1.75
c/b = 196 / 112 = 1.75
d/c = 343 / 196 = 1.75
The common ratio = 1.75

Explanation:
Function notation is a system of representing functions.
Functions are special types of relations. If a relation produces exactly one output (
y
) for each input (
x
), then it is called a function.
You can write a relation in function notation by replacing y with f
(
x
)
. This is pronounced "f of x", and means "the value of the function given the input x
.
N= 2
Substitute 2 in for n in expression
=(5 + n) ÷ (n - 1)
=(5 + 2) ÷ (2 - 1)
=7 ÷ 1
=7
If n= 2, the expression equals 7.

Answer:
D is your answer
Step-by-step explanation:
All you have to do is just input the numbers into the equation.
y=1.55(84400)+110419
y=130820+110419
$241,239
So, D is your answer.

Answer:
x= ±2 sqrt(3)
Step-by-step explanation:
4x^2+11= 59
Subtract 11 from each side
4x^2+11-11= 59-11
4x^2 = 48
Divide by 4
4/4x^2 = 48/4
x^2 = 12
Take the square root of each side
sqrt(x^2) = sqrt(12)
x = ±sqrt(4*3)
x= ±2 sqrt(3)
