The length of A"B" is 20 units

<h3>How to determine the length of A'B'?</h3>

From the figure, we have:

A = (1, 4)

B = (4, 8)

The distance AB is:

AB = \sqrt{(x_2 -x_1)^2 + (y_2 -y_1)^2

So, we have:

AB = \sqrt{(1 -4)^2 + (4-8)^2

Evaluate

AB = \sqrt{25

This gives

AB = 5

The scale factor of dilation is 4.

So, we have:

A'B' = 5 * 4

Evaluate

A'B' = 20

Hence, the length of A"B" is 20 units

A circle has a circumference of 150 meters. What is the measure of its radius? Round
Rina8888 [55]

Answer:

R = 23.9

Step-by-step explanation:

formula for circles circumfrence is, C = 2*3.14*R

in this one we have to work backwards so we plug wut we have.

150 = 2*  3.14*R

we divide 150 by 2 so it will be

75 = 3.14R

now we divide 75 by pi so wwe get

23.8732414638 = R

Now we round it to nearest tenth

R = 23.9

30 Points! please help!
SVEN [57.7K]

Answer:

18) 4 * 10 ^ -10

19) t ^ 9

Step-by-step explanation:

18. When multiplying in scientific notation, just multiply the regular numbers together and add the exponents for the tens.

So it'll be 40 * 10^-11

However, the beginning number should have the decimal right after the 4, not any place after (for example, it's 3.056, not 30.56 or 3056.)

To fix this, move the decimal place forward one space from 40. to 4.0, and add 1 to the -11 power.

So the answer is now 4 * 10^-10

19. When dividing exponents, if the base number is the same, you can divide. (Basically, you can not divide x^2 and y^3 because x and y aren't the same)

Since in this case it's t, you can divide.

Dividing exponents is simple: just subtract them.

14 - 5 = 9

so the answer is t ^ 9

a cleaning company charges a flat fee of $8 and $30 per hour to clean a home. write an equation that can represent the situation
Andru [333]
In order to reach the total cost of $128, you need to find the number of hours the company cleaned. The equation to do so would be
 
  30x+ 8 = 128

If you subtract 8 from both sides and then divide by 30 you'll find that x=4.
