Answer:

Step-by-step explanation:

Diameter = 28 cm

therefore, radius = 28 / 2 = 14 cm

Circumference = 2 π r

= 2 × 22 / 7 × 14

= <u><em>88 cm</em></u>

Hope this helps

plz mark as brainliest!!!!!

Given a polynomial function f(x), describe the effects on the y-intercept, regions where the graph is increasing and decreasing,
alina1380 [7]

Answer:

We are have the function f(x).

Part 1: It is given that the function f(x) is transformed to f(x)+2.

This gives us that the function is translated 2 units upwards.

As, the y-intercept of f(x) is f(0). So, the y-intercept of f(x)+2 is f(0)+2, which is also translated 2 units up.

Translation does not change the behavior of the function.

So, if f(x) is increasing (or deceasing), then f(x)+2 will be increasing(or decreasing) respectively.

Moreover, f(x)+2 will be even or odd if f(x) is even or odd respectively.

Part 2: It is given that the function f(x) is transformed to \frac{-1}{2}f(x)

This gives us that the function is shrinked vertically by a factor of \frac{1}{2} followed by a reflection across x-axis.

Also, the y-intercept of is \frac{-1}{2}f(0).

The graph of f(x) after changing to \frac{-1}{2}f(x) will flip over the x-axis.

So, the function \frac{-1}{2}f(x) will increase or decrease when f(x) decrease or increase respectively.

Moreover, \frac{-1}{2}f(x) will be even if f(x) is even or odd respectively.

Given the sets A = {-4, -1, 3, 5, 9} and B = {-2, -1, 0, 1, 2, 3}, the set AUB (u is upside down) is given by:
ki77a [65]

The upside down U is the symbol for the intersection of sets. The intersection of two sets is the set that contains the elements that are common to both sets. Which elements are both in set A and in set B?

Answer: {-1, 3}

One room of an apartment is 12 ft. by 15 ft. The walls are 9 1/2 feet high. How much paint will you need to paint the four walls
Svetlanka [38]

-- The left side wall and the right side wall are each (15 x 9) = 135 square ft.

-- The front wall and the back wall are each (12 x 9) = 108 square ft.

-- The total area of all 4 walls is (135 + 108 + 135 + 108) = 486 square ft.

-- You need 1 gallon of paint for every 425 square ft.
How many times will you need to cover 425 square ft ?

         486 / 425 = 1.144 times

-- So you need  1.144 gallons in order to paint all 4 walls.
When rounded to the nearest 1/10th gallon, the number is <em>1.1 gallons</em>.
<em>That choice is not found</em> on the list of choices given with the question.

-- Even so, that figure of "1.1 gallons" is probably a little more than you
actually need in order to paint the 4 walls . . .  That quantity of paint includes
enough to paint over the door, the windows, and all of the electrical outlets !

To simplify the equation 3(5 + 2x), the distributive factor must be used, so the number outside the bracket (3), must be distributed (or multiplied) with each of the terms inside the brackets (5 and 2x) and then simplify

<span>3(5 + 2x)
</span>3(5) + 3(2x)
15 + 6x
