Suppose you were on vacation but forgot your smart phone charging cable. Your phone battery died after two whole days 48 hours of use. The situation is modeled by the equation FH equals 48 minus age over 48 where age is the hours of cell phone use an FH is the percentage of battery life left

answer: options?

step-by-step explanation:

definitely a. the others have almost all data points on one side of the line.

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.
