Acompany that manufactures mountain bikes makes a daily profit p according to the equation p equals negative 100 x squared plus 4900 x minus 57 comma 424, where p is measured in dollars and x is the number of mountain bikes made per day. find the number of mountain bikes that must be made each day to produce a zero profit for the company.

sorry i dont know my friend

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.

you estimate that the angle of elevation to the top of the 86th floor (the observatory) is 82 .the total height of the building is another 123 meters above the 86th floor.
