I think the correct answers from the choices listed above are the first and the fourth option. The statements that are true about a reflection would be that it  is an isometry and the it flips a plane about a fixed line. <span>A </span>reflection<span> over a line k (notation rk) is a transformation in which each point of the original figure (pre-image) has an image that is the same distance from line k.</span>

shutvik [7]

Answer: i'm not really sure how to answer this one but i think you're wanting an answer to something. the equation for it would be 5 + 5x meaning the 5 is already there, and x is for the minutes that are they filling it up. so if the question asks how much after 5 minutes, you simply just put the 5 in place for the x.

Enter the amplitude of the function f(x) . f(x)=3/4cos(3x)+4
Alisiya [41]

Answer:

The amplitude is \frac{3}{4}

Step-by-step explanation:

Let f(x) be a sinusoid function that has the following format:

f(x) = bsin(wx + s) + h

Then b is the amplitude of the function

h is the vertical displacement of the wave

s is the phase angle

\frac{2\pi}{w} is the period.

In this problem f (x) = \frac{3}{4}cos(3x) +4

Then \frac{3}{4} = b

Therefore the amplitude of the function is \frac{3}{4}

The amplitude is a measure of the vertical size of the sinx wave

Telephone plan consist of a monthly fee of $20 plus $.20 per minute for long distance calls made write an equation for the total
HACTEHA [7]

Answer:

C=20+0.20N

Step-by-step explanation:

Fixed monthly fee = $20

Amount charged per minute for long distance calls = $0.20

C denotes total cost such that N minutes are used for long distance calls.

Amount charged for N minutes for long distance calls =0.20N

Therefore, an equation for the total cost, C, when N minutes are used for long distance calls is C=20+0.20N

The Dowers make pumpkin pie. If each person wants three slices of pie, and each pie is Cut into 9 slices, how many pies do they
Mrac [35]

The Dowers need to make 5 pies for 15 people.

Step-by-step explanation:

Given,

1 person = 3 slices of pie

15 persons = 15*3 = 45 slices of pie

It is also given that;

9 slices of pie = 1 whole pie

1 slice of pie = \frac{1}{9}\ pie

45 slices of pie = \frac{1}{9}*45

45 slices of pie = 5 whole pies

The Dowers need to make 5 pies for 15 people.
