A portion of a roller coaster track with a maximum height of 90 feet is in the shape of a parabola. Write and graph a quadratic function [f] that models this portion of the track, with a vertex of (25, 90), and passing through the point (50, 0). f(x)=

yes

step-by-step explanation:

give me the question

\

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq

answer:   b

step-by-step explanation:

x2 = 16

x can not be a negative number because 16 is positive

the only answer would be positive 8  

the eight graders whould be the answer
