Which algebraic representation shows a reduction?

Mathematics
1 answer:
Grace [21]3 years ago
5 0

Answer:

D. (x, y) →(\frac{1}{2}x,\frac{1}{2}y)

Step-by-step explanation:

A dilation is a transformation which reproduces an image of the same shape as the original, but might be of a different size.

When the dilation produces a smaller image is called a reduction.

Mathematically, a reduction occurs whenever the scale factor is between 0 and 1.

Out of the options, the only one that has a scale factor less than one is:

(x, y) →(\frac{1}{2}x,\frac{1}{2}y)

Since the scale factor is 1/2 which is less than 1.

All other options are not reductions.

Answer:

Unit rates are expressed as a quantity of 1, such as 3 feet per second or 6 miles per hour, they are called unit rates.

In the given table shows the number of pictures taken and how much time it took.

For first camera;

Number of pictures (unit rate) per second = \frac{15}{3} =5 pictures.

For second Camera:

Number of picture per second = \frac{48}{8} =6 pictures.

For third Camera:

Number of picture per second = \frac{18}{6} =3 pictures.

The camera that takes picture the fastest is, Second Camera.

(a)

As per the given statement: At Davidson's Bike rentals, it costs $29 to rent a bike for 8 hour.

⇒ unit rate per dollar = \frac{Number of hours }{Total cost} = \frac{8}{29} = 0.2758620 hours

Therefore, 0.227 hours (nearest to hundredths) of bike use does a customer get per dollar.

(b)

Jessica bought 18 pounds of sugar for $10.

unit rate per dollar = \frac{18}{10} =1.8 pounds

therefore, 1.8 pounds of sugar did she get per dollar.
