Answer:
The length of the bridge is 126.492 feet.
Step-by-step explanation:
Let
, where
is the position from the middle of the bridge, measured in feet, and
is the height of the bridge at a location of x feet, measured in feet. In this case, the length of the bridge is represented by the distance between the x-intercepts of the parabola, which we now find by factorization:
(Eq. 1)



Given that the parabola is symmetrical with respect to y-axis, then the length is two times the magnitude of the value found above, that is:


The length of the bridge is 126.492 feet.
Answer:
A
Step-by-step explanation:
I'm not sure but I think the answer might be, (3x-1)^2/9
Answer:
It is True.
Step-by-step explanation:
Let's solve the rational equation and if it is ture.
x/8 = 5/4
Cross multiplying, we get
4x = 5*8
4x = 40
Dividing both sides by 4, we get
x = 10.
Therefore, x = 10 is true.

Answer:
(multiple)
Step-by-step explanation:
it says 2,0 which 2 is the bottom line. You go to 2 at the bottom then go up to 0. Therefore, 2 is C. Start on the bottom, and move your finger up until you hit the second number. Right in the middle of that is your answer. Hope this helps! :)
