Aubrey and Charlie are driving to a city that is 120 mi from their house. They have already traveled 20 mi, and they are driving
Zarrin [17]

Answer:  The function that models the distance they drive is

f(x) = 50x + 20 where x is the time in hours

reasonable domain:  0 ≤ x ≤ 3

Step-by-step explanation:

examples:

95 = 50(1.5) + 20 After driving another hour and a half, they will have driven a total of 95 miles.

120 = 50(2) + 20  This means that after 2 more hours they will reach their destination.

There is a little ambiguity in the question. The function could be written as if they are starting out.  f(x) = 50t  

20 = 50(.4)  At 50 mph it took .4 hours to go 20 miles.

120 = 5(2.4)  The whole trip took 2.4 hours.

Please show me the steps of doing this question if you know how, ty.

The arc length is the product of the angle measure in radians and the radius.

... s = r·θ

So, the angle in radians is the ratio of arc length to radius.

... θ = s/r

To convert from radians to degrees, multiply by the conversion factor 180°/(π radians).

... y = s/r·(180°/π)

Then the angle is between

... 15/20·180/π ≈ 42.97

and

... 16/20·180/π ≈ 45.84

Suitable integers in this range are 43, 44, and 45.

One possible integer value of y is 44.
