Given a point A(-3,-1), it is dilated by some scale
Sidana [21]

Answer:

B' = (-3, -15)

Step-by-step explanation:

Given

A = (-3,-1)

A' = (-9,-3)

B = (-1,-5)

Required

Determine the coordinates of B'

Since A' is the image of A; we need to first calculate the scale factor using

A' = A * Scale\ factor

Make Scale Factor the subject

Scale\ Factor = \frac{A'}{A}

Substitute values for A' and A

Scale\ Factor = \frac{(-9,-3)}{(-3, -1)}

Factorize the numerator

Scale\ Factor = \frac{3 * (-3,-1)}{(-3, -1)}

Scale\ Factor = \frac{3 * 1}{1}

Scale\ Factor = 3

The coordinates of B' is then calculated as follows:

B' = B * Scale\ Factor

Substitute values for B and Scale Factor

B' = (-1,-5) * 3

B' = (-3, -15)

suppose the sales tax rate in your area is 7.5%. explain how to determine the total cost, including tax, of an eReader that cost
BartSMP [9]
To find the tax you first move the decimal place 2 places to the left giving you the exact percent in decimal form. .075 is the correct decimal for this percent. You then multiply that percent by the cost of the product. (125) After multiplying you get the product $9.375. Then you round to the nearest tens place giving you $9.38

Alona [7]

Answer:

option: A and Option: B are correct.

Step-by-step explanation:

We are given a scatter plot we are asked to find which of the given statements hold true such that it's ranges describe the cluster in the scatter plot.

Clearly from the scatter plot we could see that:

The most of the points are between 6-12 years of experience in the scatter plot.

also the earnings are between $40,000 and $60,000 that covers most of the data.

Hence, option A. ( A.  between 6 and 12 years of experience) and Option B ( B.

between $40,000 and $60,000 ) are correct.
