Answer:

Volume of the gigantic fridge is 2.5 times the volume of regular fridge.

Step-by-step explanation:

This question is incomplete; here is the complete question.

Katie is buying a refrigerator for her apartment. She's choosing between a regular fridge and a gigantic fridge (details are shown in the table below). She notices that the gigantic fridge costs 3 times as much as the regular fridge.

How many times as great is the volume of the gigantic fridge as the volume of the regular fridge?

Area of the base, Height, Price

Regular Fridge: 1m² / 2m / $200

Large Fridge: 2m² / $\frac{5}{2}$ m / $600

In this question cost of the large fridge is 3 times as much as the regular fridge.

Area of the base of regular fridge = 1m²

Height of the regular fridge = 2m

So volume of this fridge = 1×2 = 2m³

Area of the base of the large fridge = 2m²

Height of the large fridge = $\frac{5}{2}$ m

Volume of the large fridge = $\frac{5\times 2}{2}$ = 5m³

Ratio of the volumes of the large and regular fridge = $\frac{5}{2}=2.5:1$

Therefore, volume of the gigantic fridge is 2.5 times the volume of regular fridge.

F(x)= square root of x-5. find f-1 (x) and it’s domain

gayaneshka [121]

Answer:

Option B.

Step-by-step explanation:

Inverse function:

Suppose we have a function y = f(x). To find the inverse function, we exchange x and y on the original function, and then isolate y.

The domain of the inverse function(x values) is the range of the original function(y values).

Original function:

$f(x) = \sqrt{x} - 5$

Domain is $[0,\infty)$ , and when $x = 0, f(x) = -5$ . So the range is $[-5,\infty]$ , that is, $y \geq -5$

Inverse function:

$y = \sqrt{x} - 5$

Exchanging x and y

$x = \sqrt{y} - 5$

$\sqrt{y} = x + 5$

$(\sqrt{y})^2 = (x+5)^2$

$y = (x+5)^2$

The inverse function is $f^{-1}(x) = (x+5)^2$

Domain:

Range of the original function is $y \geq -5$ , so the domain of the inverse function is $x \geq -5$ . The correct answer is given by option B.
