Model 3: another plan to secure the roller coaster involves placing two concrete struts on either side of the center of the leg of the roller coaster to add reinforcement against southerly winds in the region. again, using the center of the half-circle as the origin, the struts are modeled by the equations and . a vertical reinforcement beam will extend from one strut to the other when the two cables are 2 feet apart. 8. graph the two struts on the model of the roller coaster. take a screenshot of your graph and paste the image below, or sketch a graph by hand. (5 points) recall that a reinforcement beam will extend from one strut to the other when the two struts are 2 feet apart. 9. algebraically determine the x -value of where the beam should be placed. (15 points) 10. explain where to place the beam. (10 points)

step-by-step explanation:

25 questions , because they start with 100.  

350-100=250 .  

. 250/10=25

step-by-step explanation:

first take off 100, then what x 10 = 250? that is your answer. (25)

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.
