Answer:

Since dilation is not mentioned in the answer options, thus, the correct option is 'None of the above'.

Step-by-step explanation:

We know that when an object is dilated by a scale factor, it gets reduced, stretched, or remains the same, depending upon the value of the scale factor.

  • If the scale factor > 1, the image is enlarged
  • If the scale factor is between 0 and 1, it gets shrunk
  • If the scale factor = 1, the object and the image are congruent

The figure seems to have enlarged by a certain scale factor. Thus, the figure b is a result of dilation of the original figure by a certain scale factor.

Rotation, Reflection, and translation do not affect the size of the original figure.

Since dilation is not mentioned in the answer options, thus, the correct option is 'None of the above'.

A bowl contains 3 red, 8 blue, and 7 black beads. Margaret randomly selects 3 beads one after the other without replacement. Fin
r-ruslan [8.4K]
Total number of beads = 3 + 8 + 7 = 18. P(red) = total number of red/total number of beads = 3/18 = 1/6. P(blue) = total number of blue beads/total number of beads left after replacement = 8/17. P(black) = total number of black beads/total number of beads left after replacement = 7/16. Therefore P(red) = 1/6. P(blue) = 8/17. P(black) = 7/16.

A sales team estimates that the number of new phones they will sell is a function of the price that they set. They estimate that
anygoal [31]

Answer:

<h2>The price is 860 dollars.</h2>

Step-by-step explanation:

The revenue of the company is given by (1720 - x)x, which is a polynomial of x, the price of the new phone.

The revenue of the company will be the highest, if \frac{d ((1720 - x)x)}{dx} = 0, that is

1720 - 2x = 0

or, x = 860.

Hence, the price of the new phone to maximize the company's revenue is 860 dollars.
