Length of Xianren Bridge is 400 feet.
l represents the length of other natural arches.
Since, Xianren Bridge is the longest arch, we have,
l < 400
Let's graph this inequality.
Take the other natural arches along x-axis and the lengths along y-axis.
Clearly, the graph of l = 400 is a straight line parallel to x-axis.
So, l < 400 is the region below the line l = 400.
Answer:
5 per hour
Step-by-step explanation:
15 miles the total amount he ran divided by 3 the total amount of time
15/3=5 so John ran 5 mph
The third term, fourth term and tenth term are -1, -3, -15 respectively.

What is a sequence?</h3>
A sequence is a pattern of numbers in which successive terms differ by an constant term called the common difference or ratio.
Analysis:
For a sequence defined by the rule A(n) = 3 + (n-1)(-2)
Third term, n = 3
A(3) = 3 + (3-1)(-2) = -1
Fourth term, n = 4
A(4) = 3 + (4-1)(-2) = -3
Tenth term, n = 10
A(10) = 3 + (10-1)(-2) = -15
In conclusion, the third, fourth, tenth terms are -1, -3 and -15 respectively.
