2.6 • 10^10 = 26,000,000,000
4.94 • 10^13 = 49,400,000,000,000

49,400,000,000,000/26,000,000,000= 1900

And adult had 1900 times more cells than a newborn. Or if you want to put it in scientific notation it would be 1.9 • 10^3

What is true of the function g(x)=-2x^2+5?

mart [117]

Answer:

C) The variable x represents the independent variable.

Step-by-step explanation:

The given function is $g(x)=-2x^2+5$ .

g(x) is NOT the multiplication of g and x because g is a function of x.

$x$ is the input of the function.

$-2x^2+5$ is the output of the function.

The variable $x$ is called the independent variable because we plug in values of x to find g.

The variable g represents the output of the function NOT the input.

The correct choice is C
