A grown man will burn roughly 120 calories for each mile run. How many calories will be burned when a grown man runs 6.5 miles (that is info for my questions)my questions: What is the independent quantity?
What is the dependent quantity?
Write an eqaution to solve the problem?
And Solve the eqaution?

The independent quantity is 120, as it will never change.

The dependent quantity is x, or 6.5 in this case, because that number will vary

120x = y. Where x is the amount of miles ran, and y is the total calories burned

Since we know that x=6.5, we can replace x for 6.5.

120(6.5)=y

780=y

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.

391.6 is the correct answer
