A ladder reaches 2 m up a wall. The foot of the ladder is 0.4 m from the wall. For safety reasons, the slope should be between 6.3 and 9.5. Is this ladder within the safe range?

41*67/2=1373.5

step-by-step explanation:

i just used a calculator

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.

his answer is incorrect. i just used it, and it said it was incorrect. the answer is 0.
