$\frac{1}{2} ( \frac{2}{3} + \frac{3}{4}) \\ = \frac{1}{2} ( \frac{2 \times 4}{3 \times 4} + \frac{3 \times 3}{4 \times 3} ) \\ = \frac{1}{2} ( \frac{8}{12} + \frac{9}{12} ) \\ = \frac{1}{2} ( \frac{8 + 9}{12} ) \\ = \frac{1}{2} ( \frac{17}{12} ) \\ = \frac{1 \times 17}{2 \times 12} \\ = \frac{17}{24}$
The answer is 17/24

<u>Answer:</u>

Height of cables = 23.75 meters

<u>Step-by-step explanation:</u>

We are given that the road is suspended from twin towers whose cables are parabolic in shape.

For this situation, imagine a graph where the x-axis represent the road surface and the point (0,0) represents the point that is on the road surface midway between the two towers.

Then draw a parabola having vertex at (0,0) and curving upwards on either side of the vertex at a distance of $x = 600$ or $x = -600$ , and y at 95.
