Please ANswer ASAP & show all work. If you put an incomplete or absurd answer I WILL report you. The scale factor of a model plane to the actual plane is 1 to 20.
Find the wing area of the model if the wing area of the actual plane is 400 ft^2

Step-by-step explanation:

The scale factor = 1 : 20

The area is the product of two dimensions, so the area of the model part to actual part is:

If the actual plane has wing area of 400 ft², then the model will have wing area:

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.
