A high fountain of water is located at the center of a circular pool as in Figure P1.61. Not wishing to get his feet
wet, a student walks around the pool and measures its
circumference to be 15.0 m. Next, the student stands at
the edge of the pool and uses a protractor to gauge the
angle of elevation of the top of the fountain to be 55.0°.
How high is the fountain?

step-by-step explanation:

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.

given the equation is 8+9z=-6, the first step would be to subtract the 8 from both sides:

8+9z-8=-6-8

since 8 minus 8 = 0, this would cancel out the 8. and since -6 minus 8 equals -14, the equation would look like this

9z = -14
