3) On as suspension bridge, the roadway is hung from cables hanging between support towers. The cable of on bridge is in the shape of a parabola that can be represented by the equation y = 0.1x2 – 7x +
150, where y is the height in feet of the cable above the roadway at the distance x from the support
tower
a. What is the closest the cable comes to the roadway?
b. How far from the support tower does this occur?

answer: $201

step-by-step explanation: to get the answer, you first get 3 nieces that he sold and multiply it by 67 and get $201, so he earned $201 selling his nieces.

step-by-step explanation:

let's first notice, the center of the hyperbola is at the origin, since the focus points are equidistantly 3 units away from the origin, that also means that the distance "c" from the center to either focus is 3.

it should also be notable that, the traverse axis for this hyperbola is vertical, or namely over the y-axis and therefore, the positive fraction will be the one with y-variable.

the traverse "a" component or distance from the center to either vertex is not 2, is more than 2, so we can safely put it at √5 ≈ 2.24.
