A suspension bridge with weight uniformly distributed along its length has twin towers that extend 70 meters above the road surf
1 answer:
Answer:
17.5 m
Step-by-step explanation:
The height of a parabola above its vertex is proportional to the square of the distance from the vertex.
<h3>Cable height</h3>The towers are 1200 m apart, so each is 600 m from center. The location of interest is 300 m from center, so 1/2 the distance to a tower. Since the height is proportional to the square of the distance, the height half-way to the tower will be (1/2)² = 1/4 the height of the tower.
(1/2)²×(70 m) = 17.5 m
The height of the cable 300 m from center will be 17.5 meters.

Answer: There is 225 millimeters of slushy originally in the cup.
Explanation:
Since we have given that
Rate at which she drink the slushy = 4.5 millimeters
Time taken to drink the slushy by Mariana = 17 seconds
Total quantity she drank is given by
Still there is left some slushy,
Quantity of slushy left =148.5 millimeters
Total quantity of slushy originally in the cup was given by
Hence, there is 225 millimeters of slushy originally in the cup.
