Since we are only given with a single point and we are given a proportional relationship, then we can make the assumption that when one variable is 0, the other is also 0. So, we can make the equation:
y/x = 4 / 20 or
y = x/5
<span> Luis and his
family flew 51 487 miles. This needs to be rounded to the nearest thousands to
know how many miles did Luis and his family flew?
=> 51 487 = where 5 ten thousands, 1 thousands, 4 hundreds, 8 tens and 7
ones.
=> 51 487 = 50 000 + 1 000 + 400 + 80 + 7
=> Round to the nearest thousands. The thousands value is 1, and the number
next to thousands is 4, which is below 5. SO we need to round down.
=> 51 000 miles.

Answer:
You need to show a graph
Step-by-step explanation:
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.
