You ask an employee to string holiday lights around the perimeter of a circular room. The room is 30 feet in diameter. How many

Arturiano [62]

Answer: 94.24 feet.

Step-by-step explanation:

1. To solve this exercise you must apply the formula for calculate the perimeter of a circle, which is shown below:

$P=2r\pi$

Where $r$ is the radius of the circle.

2. You can calculate the radius of the circle by dividing the diameter by 2, as following:

$r=\frac{30ft}{2}\\r=15ft$

3. Substitute this value into the formula. Then, you obtain that the result is:

$P=(2)(15ft)(\pi)\\P=94.24ft$

Which unit rate is the lowest price per ounce? Choice A: 10 ounces of chocolate chips for $1.66 Choice B: 20 ounces of chocolate

Goryan [66]

C.

To find out the rates, you must multiply or divied the ounces and price of on bag of chips to equal the other.

You can divied the 20 ounces into 10 ounces, so you must also divide 3.32 by.
The equals 1.66

10 POINTS!! PLEASE HELP ASAP!!

Ber [7]

If the polygons are similar, then we can set up a similarity ratio using sides AB and EF and any other 2 sides where both side lengths are given. That appears to be true for sides BC and FG. Our similarity ratio would be this then, going from the bigger polygon stuff on top and the smaller polygon stuff on bottom:

$\frac{8}{6}=\frac{6}{y}$ .

If we cross multiply we have 8y = 36 and divide both sides by 8 to get that y = 4.5. There you go!

The graph of f '(x) is continuous and decreasing with an x-intercept at x = 2. Which of the following statements must be true? (

bixtya [17]

Answer:

The graph of f is always concave down ⇒ the first answer

Step-by-step explanation:

* Lets explain how to solve the problem

- Remember that : If f(x) is a function then the solutions to the

equation f′(x) = 0 gives the maximum and minimum values to f(x)

- The value of x gives maximum if f′′(x) is negative and minimum if

f′′(x) is positive.

- Inflection points of the function f(x) are found the solutions of the

equation f′′(x) = 0

* Lets solve the problem

- The graph of f'(x) is continuous means that the graph is unbroken line

- The graph of f'(x) decreasing with an x-intercept at x = 2 means

f'(2) = 0

- The differentiation of a function equal to zero at the critical point

(minimum or maximum) of the function

∵ f'(x) = 0 at x = 2

∴ The x-coordinate of the critical point of f(x) is 2

- If the differentiation of the function is decreasing, then the critical

point of the function is maximum point

∵ f'(x) is decreasing

∴ The critical point of the f(x) is maximum point

- That means the slope of curve is negative

∴ The graph of f is concave down at x = 2

* The right answer is the graph of f is always concave down
