PLEASE HELP What is the distance between points Rand S, to the nearest tenth of a unit? A. 6.3
B. 7.2
C. 14.4
D.20.0

C. 14.4

Step-by-step explanation:

We need to find the distance between the points vertically, horizontally, and finally diagonally. These distances will ultimately form a right triangle meaning we will solve the distance between the points with the Pythagorean Theorem.

X-axis distance = 4 - (-8) = 12

Y-axis distance = 2 - (-6) = 8

Now we use the Pythagorean Theorem and substitute the calculated values for a and b.

a² + b² = c²

12² + 8² = c²

144 + 64 = c²

208 = c²

14.4 = c

5.5

step-by-step explanation:

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)
