Answer:

11/20

3/5

7/10

13/20

Step-by-step explanation:

A rational number is a number that can be derived by dividing 2 whole numbers

1/2 = 0.5 0r 50%

3/4 = 0.75 75%

Between 50% and 75% are 51 - 74 which can be expressed as rational numbers

3/5 = 0.6

7/10 = 0.7

11/20 = 0.55

13/20 = 0.65

What is the inverse of f(x)=(x-5)^2 for x greater or equal to 5 where function g is the inverse of function f

koban [17]

Answer:

$y=\sqrt{x}+5$

Step-by-step explanation:

The inverse of a function, is the function or rule formed by reflecting the line over y=x. This means essentially that all (x,y) values from the original function switch to (y,x).

(x,y)--->(y,x) in the new function.

If the function has points (-3,4) and (5,-2) then the inverse has points (4,-3) and (-2, 5).

We can find the equation of the inverse by switching x and y in the equation and solving for y.

This means that $y=(x-5)^2$ becomes $x=(y-5)^2$ . We now solve for y through inverse operations.

$x=(y-5)^2$

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

Bob drives a truck for a soft drink company. His truck is filled with 15 oz cans and 70 oz bottles. Let C be the number cans and

Mekhanik [1.2K]

Answer:

Using ounces, the inequality should be:

15c + 70b < 112,000

Using pounds, the inequality should be:

0.9375c + 4.375b < 7,000

Step-by-step explanation:

1. Let's review the information provided to us to answer the question correctly:

Weight of a can of soft drink (c) = 15 ounces

Weight of a bottle of soft drink (b) = 70 ounces

The truck mist be carrying less than 7,000 pounds

2. Find the inequality describing this.

Let's recall that 1 pound = 16 ounces and 1 ounce = 0.0625 pounds

c = Number of cans in the truck

b = Number of bottles in the truck

Upon saying that, we can write the inequality either using ounces or pounds, this way:

Using ounces, the inequality should be:

15c + 70b < 7,000 * 16

15c + 70b < 112,000

Using pounds, the inequality should be:

15 * 0.0625c + 70 * 0.0625b < 7,000

0.9375c + 4.375b < 7,000
