A bridge with a parabolic arch crosses a highway that is 30 m wide. The arch is 6 m high in the center and 4 m high at the edges of the highway. How wide is the arch at ground level, to the nearest meter?

answer: that was hard but still working on it

step-by-step explanation:

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.

d) 48

16,32,48,64,80,96,112,128,144,160,176,192,208,224,240,256,272,288,304,320,336

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x
