Answer:

See attachment

Step-by-step explanation:

We want to graph

$y = 2 \cos(x) - 1$

on the interval (-2π, 2π)

First we graph

$y = \cos(x)$

Then we stretch vertically by a factor of 2 and shift down 1 unit.

Since the amplitude is 2 and the graph is shifted down 1 unit, the range of the transformed graph is

$- 3 \leqslant y \leqslant 1$

The graph is shown in the attachment

Three people share half a pizza evenly. What fractional part of the original pizza does each one get?

beks73 [17]

Answer:

The fractional part of the original pizza is $\frac{1}{6}$

Step-by-step explanation:

Let

x-----> the original pizza (complete pizza)

we know that

Half a pizza represent ------> $\frac{x}{2}$

Divide half a pizza by three people

$(\frac{x}{2})/3=\frac{x}{6}$

therefore

The fractional part of the original pizza is $\frac{1}{6}$

Find the volume of each figure. Round your answers to the nearest hundredth, if necessary

SCORPION-xisa [38]

Answer:

666.67π .ft^3

here's your solution

=> radius of cone = 10 ft

=> height of cone = 20 ft

=> volume of cone = πr^2h/3

=> putting the value of radius and height

=> volume = 10^2*20/3π

=> volume = 666.67π .ft^3

hope it helps

Are we going to start with the

romanna [79]

Answer:

multiplication.

Step-by-step explanation:

A good way to remember the order of operations is Please Excuse My Dear Aunt Sally, or PEMDAS. PEMDAS stands for Parentheses, Exponents, Multiplication/Division, Addition/Subtraction. If multiplication and division are in the same problem, you go in order. Same with addition in subtraction. What that means in this example is that since in PEMDAS, the M is first, you would multiply first instead of subtracting. :)

Please help!!! i would really apreciate it

Answer:

it should be the graph on the bottom right

Step-by-step explanation:

The income should be more than the cost in order to make a profit and that happens for Leanne when she sells 8 quilts, so the 8 should be on the x-axis (the axis named "Quilts Sold")

The income should be 0 in the beginning bc when she sells 0 quilts she will be earning 0.

after selling 8 quilts her income will be higher than her costs

(Though naming the y-axis as "profit" is not accurate bc when she sells 0 quilts she will lose money since she will be spend money to make the quilts but not earn the money to compensate for the cost).

with all of these reasons combined the correct should be the one on the bottom right
