The height of the tunnel 5 feet from the edge is 13.82 feet option second 13.82 feet is correct.
<h3>What is an ellipse?</h3>
An ellipse is a locus of a point that moves in a plane such that the sum of its distances from the two points called focus adds up to a constant. It is taken from the cone by cutting it at an angle.
We have:
A tunnel is constructed with a semi-elliptical arch. The width of the tunnel is 60 feet, and the maximum height at the center of the tunnel is 25 feet.
2a = 60 (width of the tunnel is 60 feet)
a = 30
And the maximum height at the center of the tunnel is 25 feet
b = 25
Let's assume the center of the ellipse is at the origin.
So the equation of the ellipse:

Now plug x = a - 5 = 30 - 5 = 25

After solving:


y = ±13.819 ≈ ±13.82
Height cannot be negative
y = 13.82 feet
Thus, the height of the tunnel 5 feet from the edge is 13.82 feet option second 13.82 feet is correct.

Answer:
4) Stored chemical energy is converted to mechanical energy.
Step-by-step explanation:
The battery represents energy stored in the form of chemical compounds. The motion represents mechanical energy. The transfer occurs between these forms of energy.
4) Stored chemical energy is converted to mechanical energy.
The answer is B^5 also known as answer choice A
So, what you’re doing here is basically finding the measurements of a right triangle, so we’ll use the formula
a^2+b^2=c^2
now, we plug in what we have
12^2+x^2= 19^2
144+x^2= 361
Bring the variable to one side by subtracting 144 from each side
x^2= 217
Square root each side to get rid of the exponent on the x
x= 14.7309
ANSWER:
15 inches
