Is this a function and why?

kherson [118]

It’s not a function because the domain (the X) is repeating...
X cannot repeat if you want it to be a function

Volume of cone= 1/3πr^2h

8842.24 m^3= 1/3πr^2h

1/3*3.14*33*r^2= 8842.24m^3

r^2 = 8842.24*3/3.14*33

r^2= 26526.72/103.62

r^2 = 256

r= √256

r= 16m

Hope it helps. Please mark brainliest.

The right answer is Option C.

Step-by-step explanation:

Given inequality is

6(2x-1) > 24

Solving the inequality

$6*2x-1*6>24\\12x-6>24$

Adding 6 on both sides

$12x-6+6>24+6\\12x>30$

Dividing both sides by 12

$\frac{12x}{12}>\frac{30}{12}\\x>\frac{5}{2}$

Therefore,

$x>\frac{5}{2}$

The right answer is Option C.
