The unit rate is a comparison of two different quantities when they are combined.

Unit rates actually are utilized by people frequently in every day life. A standard work week undertaken by a typical person is 40 hours per week. Unit prices are useful at grocery stores. For example, if five potatoes cost $5, the unit price is determined by dividing the total price by the number of individual potatoes, or $5 divided by 5.

If the graph of f(x) has the point (2,7) then what is one point that will be on the graph of f-1(x)

IRINA_888 [86]

The graph of f^-1 (x) is called the inverse function of f (x). The relationship between the two is that the point (x,y) is on the graph of f (x) if and only if the point (y,x) is on the graph of f^-1 (x).

This means that if the point (2, 7) is on f (x), therefore the point (7, 2) is on f^-1 (x).

The length of a rectangle is twice its width. If the area of the rectangle is 5 , find its perimeter

gizmo_the_mogwai [7]

Answer:

9.48

Step-by-step explanation:

The perimeter of a rectangle is the distance around the the shape. It can be found by adding each side of the shape to find a total. In contrast, the area of a shape is the amount inside a shape. It is found using multiplication or A = l*w. Since the width is w and the length is twice its width or 2w, use these expressions in the area formula to find their amount. Then add them together to find the perimeter.

$A = l*w5 = w(2w)\\5 = 2w^2\\2.5 = w^2\\1.58 = w$
