The slope of the perpendicular line of y=5x would be -1/5, since slopes are always opposite reciprocals when they are perpendicular to each other.
The square of the distance between C(4, -5) and P(1, -2) is given by the Pythagorean theorem as
(4-1)² +(-5-(-2))² = 18
This is the square of the radius of the circle, so we can use it for r² in the formula
(x -h)² +(y -k)² = r² . . . . . . . circle of radius r and center (h, k)
Your circle has equation ...
(x -4)² +(y +5)² = 18
Answer:
5 cm
Step-by-step explanation:
32 / 4 = 8
40 / 8 = x
40 / 8 = 5
32 and 4 are corresponding, and 40 and x are as well. Find the relation between 32 and 4, then apply it to 40 to find the value of x.
