Christian pays $15 to join a music streaming service. He also pays $0.99 for each song he downloads from the same service. Which function can be used to find, y, the the amount of money Christian spends for x downloaded songs?
Which graph represents y as a function of x?

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,

here is the

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:
