1.5: Exploring Arithmetic Sequences UT
3. A grocery store worker has to collect all the shopping carts left out in the parking
lot. He collects 4 carts and measures the length of the 4 carts he is pushing to be 51
inches. He collects another cart for a total of 5 carts and measures the length of the
5 carts to be 57 inches.
(a) He sees that there are a total of 21 carts in the parking lot. How long
will the line of 21 carts be?

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.

multiply length by height. multiply the length by the height, and then double the product. work out 10 x 10 results = 100 square inches, then work out 100 x 2 = 200. the answer is 200 square inches.

step-by-step explanation:

y=sec x is the correct answer
