Answer:
Step-by-step explanation:
The zero of a function is also known as the x-intercept of a function. The x-intercept of a function exists where y = 0. So we will begin by setting each of those lines = 0:
4x - 20 = 0 and -1/2x + k = 0 and then solve each for x:
4x = 20 so
x = 5 and
-1/2x = -k and
1/2x = k so
x = 2k. Now we set the 2 x expressions equal to each other and solve for k:
5 = 2k so
k = 5/2
Answer:
13,250,000 feet or 13.25 million feet
Step-by-step explanation:
Each person in the line has a shoulder width of 1.325 feet.
For each person, there is a width of 1.325 ft. There are 10 million people.
Since:
10 million = 10,000,000
The total length must be:
