Answer:

Step-by-step explanation:
we know that
The equation of the circle in center radius form is equal to

where
(h,k) is the center of the circle
r is the radius of the circle
In this problem we have

substitute


We are given

where
y is the cost in dollars
x is distance in dollars
now, we can find derivative



so,

So,
the rate of change of the cost in dollars with respect to the number of miles is 1.5.........Answer
<span>The parent cosine function can be transformed and translated. So, from the basic function cos(x) we can obtain function acos(bx+c). In our case, a=3- amplitude, b=10- the period change and c=-pi- the phase shift. So, the parent cosine function is mutiplied with 3 (which gives the amplitude of the function, 3*0.5=1.5). The period of the function is changed, and is 2pi/b=2pi/10=pi/5 and the cos(x) is phase shifted for c/b=-pi/10.</span>
