Answer:
1.a. not a function
1.b. function
1.c. function
1.d. not a function
1.e. not a function
1.f. not a function
Step-by-step explanation:
1.a.
The arrows from x to y show that the ordered pairs of this function are:
(1, 4), (1, 5), (0, 7), (1, 6), (2, 5).
Since the x-coordinate 1 is used in two different ordered pairs, (1, 4) and (1, 5), this relation is not a function.
1.b.
Each x-coordinate is used only once, so this relation is a function.
1.c.
All x-coordinates are different. Function.
1.d.
Two ordered pairs have the same x-coordinate. Not a function.
1.e.
Two ordered pairs have the same x-coordinate. Not a function.
1.f.
Two ordered pairs have the same x-coordinate. It does not pass the vertical line test. Not a function.
Answer:
The world human population has a natural growth rate (r) of approximately 2 percent per year.
Step-by-step explanation:
First convert 6.5% into a decimal and get .065
next multiply 4226 by .065 to find 6.5% of $4226 to find Sam's commission
4226 times .065=274.69
answer: $274.69 is Sam's commission
Answer and Step-by-step explanation:
Answer:
3z/10 or z/3.3333...
Step-by-step explanation:
z/(3 3/9) = z/(30/9) = z/(10/3)
z*3/10 = 3z/10 = z/3.3333...
