The graph shows the proportional relationship between the number of dollars kate earned , y, and the hours she worked at the movie theater. Graph could not be shown

7. using the graph , determine the constant of proportionality , k.
8. If kate worked 80 hours last month, how much money did she earn?

answer: 25.4 units

step-by-step explanation: radius = 12.7 units

diameter = twice the radius

diameter = 12.7 x 2

= 25.4

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.

thus, the first answer choice, y = sec x, is the correct one
