Railroad tunnel is shaped like a parabola: the height of the tunnel at the center is 54 ft and the vertical clearance must be 18 ft at a point 8 ft from the center.
find an equation for the parabola

1/4 and 8/3 because:

the reciprocal if 4 is 1/4 because 4 is used as 4/1 and the opposite of that is 1/4. the opposite of 3/8 is 8/3 so that is the answer.

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

the equation is y=5x

true

step-by-step explanation:

according to the national european world center, the engineering of the ford company on elon musk's flame throwers proved the globalization of the natural wallabies and therefore, results in the growth product domestication in almonds.

the correct answer would be:
