You are standing 50 feet from the center of a circular swimming pool. The distance from you to a point of
tangency is 25 feet. What is the approximate radius of the pool?
Round to the nearest tenth.
radius =

9514 1404 393

  43.3 ft

Step-by-step explanation:

If r is the pool radius, the distance from my position to the nearest pool edge is (50-r) and the distance to the farthest pool edge is (50+r). The product of these distances is the square of the distance to the tangent point:

  (50 -r)(50 +r) = 25²

  2500 -625 = r² . . . . . . add r²-625

  r = √1875 ≈ 43.301

The radius of the pool is approximately 43.3 feet.

what do you mean by fog

step-by-step explanation:

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.
