A circle is shown. A secant goes through the center point and intersects a tangent at a point outside of the circle. The length
of the tangent is 7 inches. The length of the external part of the secant is 4 inches. Kylie writes an equation to solve for the diameter, d, of the circle shown. Solve Kylie’s equation to find the diameter of the circle.
A full rotation is 360 degrees, if the fan moves 75 degrees (360-75) the fan will have a total of 285 degrees left too rotate in order to make a single, full rotation.
Using the formula for slope, we can find out that So -105 is the slope, and because she bought her laptop at $1160, the y-intercept is 1160. This means that the equation is V(t)=-105t+1160.
