Step-by-step explanation:
There are 720 ways through which 3 numbers can be selected from 10 numbers to open a keypad lock.
Given that there are 10 numbers are 3 numbers are required to open a keypad lock.
Permutations are the number of ways in which objects can be selected without replacements to form subsets.
It is expressed as n=n!/(n-r)!.
Factorial of a number is the product of consecutive numbers less than the number.
Total numbers available=10
Numbers to be selected=3
Number of ways can be found by using permutations.
Number of ways =10
=10!/(10-3)!
=10!/7!
=10*9*8*7!/7!
=10*9*8
=720 ways.
Hence there are 720 ways through which 3 numbers can be selected from 10 numbers.

Figure 1 is the original figure, while figure 2 is
modified, so that a triangle and a rectangle can be easily observed.
The area of triangle and rectangle represents the
total number of cubic feet of storage multiply by the number of days of storage
usage.
Hence
Total Area = Area of triangle + Area of rectangle
= 30 x 10,000 + ½ 30 x (30,000 – 10,000)
= 300,000 + 300,000
= 600,000
As 10 cubic feet of storage cost $5 for a day, so
total amount company have to pay
<span>= (5 x 600,000) / 10 = $300,000</span>
The x intercept is (1/2,0)
The y intercept is (0,4)
To find the x intercept, substitute 0 for y and and solve for x. To find the y intercept, substitute 0 for x and solve for y. Or you can graph the function and find the intercepts.
