Shay works each day and earns more money per hour the longer she works. write a function to represent a starting pay of $20 with an increase each hour by 4%. determine the range of the amount shay makes each hour if she can only work a total of 8 hours.
a.20 ≤ x ≤ 22.51
b.20 ≤ x ≤ 25.30
c.20 ≤ x ≤ 26.32
d.20 ≤ x ≤ 27.37

Explanation:

The function must meet the rule that the pay starts at $20 and it increases each hour by 4%.

A table will help you to visualize the rule or pattern that defines the function:

x (# hours)        pay ($) = p(x)

0                        20 . . . . . . . .  [starting pay]

1                         20 × 1.04 . . . [ increase of 4%]

2                        20 × 1.04² . . . [increase of 4% over the previous pay]

x                        20 × 1.04ˣ

Hence, the function is:    

The range is the set of possible outputs of the function. To find the range, take into account that this is a growing exponential function, meaning that the least output is the starting point, and from there the output will incrase.

The choices name x this output. Hence, the starting point is x = 20 and the upper bound is when the number of hours is 8: 20(1.04)⁸ = 27.37.

Then the range is from 20 to 27.37 (dollars), which is represented by 20 ≤ x ≤ 27.37 (option D from the choices).

  the correct choice is marked

step-by-step explanation:

the first two graphs show multiple turning points. the last graphs matches the description in every detail.

there has been genes found in the x chromosome of males that have been linked to [homo/hetero]sexuality. in addition to the reign of the x chromosome, a section of chromosome 8 has also been link to, "alot of ppl are so " these facts were proven true after a 2014 study of a gay male and his strait brother. according to newscientist.com,"chromosome 14 and is mainly active in the thyroid, but also the brain. called tshr, it makes a type of receptor protein that recognises and binds to a hormone that stimulates the thyroid. in this way, the gene plays an important role in controlling thyroid function. the fact that tshr seems to be involved in sexual orientation fits with evidence that thyroid function seems to be linked to sexuality."

in conclusion, "ppl are so gay" due to their genetics.
