if the radius of the circle becomes two times what will be the new area of the circle
Answer: So when you double the radius, the area goes up by 4 times because 2 squared is 4. The area will always go up by the square of how much the radius goes up. By contrast, the circumference will only double -- from 12.56 to 25.12 because you do not square the radius (or diameter) -- you just multiply it by pi.
Step-by-step explanation:
5 plus square root of 45 divided by 4
5+ sqrt45/4
5+5/4
6.75

Answer:
y= (x - 12)^3
y= (x - 4)^3
Step-by-step explanation:
Shift to the right is a horizontal shift so it needs to be with x in the parenthesis. And negative because it is to the right.
y= (x - 12)^3
y= (x - 4)^3
are the two that fit those criteria
Answer:
y = (x - 12)^3
y = (x - 4)^3
Step-by-step explanation:
If you look in the picture, red line is y = x^3 (the original parent equation), green line is y = (x - 4)^3, and blue line is y = (x - 12)^3
A researcher is comparing the effectiveness of three devices designed to help people who snore. There are 120 people who snore participating in the experiment. Using a table of random digits, the researcher will randomly place the participants into three equally sized treatment groups suitable for comparison.
Which design is the most appropriate for this experiment?
A Randomly number each person with 1, 2, or 3. Assign the people labeled 1 to the device 1 group, the people labeled 2 to the device 2 group, and the people labeled 3 to the device 3 group.
B Number each participant from 1 to 120. Reading numbers from left to right from a random number table, identify 80 unique numbers from 1 to 120. Assign the people whose labels are the first 40 numbers to the device 1 group. Assign the people whose labels are the second 40 numbers to the device 2 group. Assign the remaining people to the device 3 group.
C Number each participant from 000 to 119. Reading numbers from left to right on a random number table and looking at three digits at a time, identify 80 unique three-digit numbers from 000 to 119. Assign the people whose labels are the first 40 numbers to the device 1 group. Assign the people whose labels are the second 40 numbers to the device 2 group. Assign the remaining people to the device 3 group.
D Select a participant, and identify the first digit reading numbers from left to right on a random number table. If the first digit is a 1, 2, or 3, assign the participant to the device 1 group. If the first digit is a 4, 5, or 6, assign the participant to the device 2 group. If the first digit is a 7, 8, or 9, assign the participant to the device 3 group. If the first digit is a 0, skip that digit and move to the next one to assign the participant to a group. Repeat this process for each participant.

Apply the distributive property. Then simplify by combining like terms. How do you do that? 14(-7w-4)
Answer:
-98w-56
Step-by-step explanation:
Distributive property means to take the 14 and distribute and multiply by everything inside the parenthesis,
so 14(-7w) -4(14) = -98w-56
Since there are not 'like terms' you are done

By rounding to one significant figure,estimate the answer to this question: 798 divided by 8 times 41 so I know it's 800 divided by 10=80 and 41 turns to 40 so it's 80x40 but no matter what I type in it's the wrong answer :/ just wanna make sure
Answer: Try this:
Step-by-step explanation:
798 rounded to one sig. fig. = 800.
8 is already just one sig. fig.
41 rounded to one sig fig. Is 40.
800/8x40
800/320 = 2.5.......
Rounded to one sig fig. =3
Or if you left the entire equation as is and just rounded the answer to 1 sig. fig.
798/(8x41) = 2.4329.......
rounded to one sig fig =2
Without knowing what specifically the question wants estimated to one significant figure, there could be multiple answers.
The estimate of the equation to one significant figure is 2.
What is a significant figure?Significant figures are the digits in a number that is significant and required to denote a value and also add to the correctness of that value.
The way we will solve this equation is to first determine the final value and then approximate it to 1 significant figure.
[tex]\mathbf{= \dfrac{798}{8 \times 41}}[/tex]
= 2.4329
≅ 2 (to one significant figure)

A line that is not parallel nor perpendicular to y=2/4x+1
Answer:
y=2x+1
Step-by-step explanation:
Parallel = gradients are the same
Example: y=2/4x+5
Perpendicular = gradients are the inverse of each other
Example: y= -4/2x+1
Any equation would be correct unless the gradient is 2/4 or -4/2

Answer:
132-5 therefore the height from the eyes to the window is 127
100 feet away from the base of the tower
This forms two legs of a triangle
trying to find the degrees of this triangle.
Since its the two legs, you can use tanx which = to opposite side/adjacent side
Therefore, it is tanx = 127/100
