The temperature in degrees Fahrenheit at a given location goes through a similar cycle each day. The low is 30 degrees F and occurs near 6:00 am. The high is 70 degrees F and occurs near 6:00 pm which function best models the temperature as a function of the time in hours since noon?

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

27 +27 or 27times 2=54

the diffrence is 0

my dear correct answer is option number 3
