Solve the proportion: 20/16 = x/80 question 19 options: 6.25 1600 100 160

1 answer:

8 0

$\dfrac{20}{16}=\dfrac{20:4}{16:4}=\dfrac{5}{4}\\\\\dfrac{5}{4}=\dfrac{x}{80}\ \ \ \ |cross\ multiply\\\\4x=5\cdot80\\\\4x=400\ \ \ \ |divide\ both\ sides\ by\ 4\\\\\boxed{x=100}$

identify a transformation of the function f(x) = √x by observing the equation of the function g(x) = √x-2

gregori [183]

<h2>Answer:</h2>

$f(x)=\sqrt{x}$ is the Square Root Function. These are the characteristics of the graph of the square root function:

The domain of the function is the set of all non negative real numbers.

The range of the function is the set of all non negative real numbers.

The graph has an intercept at $(0,0)$ .

The graph is increasing on the interval $(0, \infty)$ .

Since the function $g(x)=\sqrt{x}-2$ , then this stands for the form:

$g(x)=f(x)-c$ . This form tells us that the graph of f has been shifted c units downward where the value c = 2 in this problem. The graphs of both functions are shown below. The red one is $f(x)$ while the blue one is $g(x)$
