Another plan to secure the roller coaster involves using a cable and strut. using the center of the half-circle as the origin, the concrete strut can be modeled by the equation y=sqrt(2x+8) and the mathematical model for the cable is y=x-8.the cable and the strut will intersect.
6. graph the cable and the strut on the model of the roller coaster using the graphing calculator. take a screenshot of your graph and paste the image below. (5 points)
7. algebraically find the point where the cable and the strut intersect. interpret your answer. (10points)

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

×=23.23
