The center of a circle is on the line y =2x and the line x=1 is tangent to the circle at (1, 6).
find the center and radius of the circle.

Step-by-step explanation:

slope of line perpendicular to x=1 is zero

eq. of line perpendicular to x=1 passing through (1,6) is

y-6=0(x-1)

or y-6=0

or y=6

to find the point of intersection of y=6 and y=2x

2x=6

x=3

so center is (3,6)

radius=√[(3-1)²+96-6)²]=2

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.

step-by-step explanation:

i believe its "c" because all of the other options include a but it could be d because there is a way of financing with cash at certain places but its uncommon.
