<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
or
, and y at 95.
We know that the equation of a parabola is in the form
and here it passes through the point
.




So new equation for parabola would be
.
Now we have to find the height
of the cable when
.

y = 23.75 meters
The correct answer is letter B
Answer:
$569.80
Step-by-step explanation:
We can use the simple interest formula for this:

<em>P = initial balance
</em>
<em>r = annual interest rate
</em>
<em>t = time
</em>
<em />
First, change 7.2% into its decimal form:
7.2% ->
-> 0.072
Next, since we are calculating for 6 months (1/2 of a year), the annual interest rate will be 0.5. Now, plug in the values:


The total amount owed in 6 months is $569.80
A linear equation would work
