Answer:

H) 3, 10, 17, 24, ...

Step-by-step explanation:

An arithmetic sequence is when the difference of the terms is same

F)2, 5, 9, 14, ...

14 - 9 = 5,
9 - 5 = 4.
5-2 = 3

5 ≠ 4 ≠ 3, no

G)100, 50, 12.5, 1.6, ...

1.6 - 12.5 = -10.9
12.5 - 50 = -37.5
50 - 100 = -50

-10.9 ≠ -37.5 ≠ -50, no

H)3, 10, 17, 24,...

24-17 = 7
17 - 10 = 7
10 - 3 = 7

7 is the common difference, yes

j) -2,-1,-1/2,-1/4

-1/4 - (-1/2) = 1/4
-1/2 - (-1) = 1/2
-1 - (-2) = 1

1/4 ≠ 1/2 ≠ 1, no

What are the roots of the polynomial equation?

Andreas93 [3]

Answer:

The roots of the polynomial equation in this case would be the intersection of the 2 polynomial functions. which are at x = 4 and x = -3

Step-by-step explanation:

The roots are found by finding the x-values of the intersections of these two cubic polynomial functions.

We could try solving algebraically, but you have the graph.

Jose works 25 hours a week at $12.50 per hour. How many weeks will he have to work to earn $3,437.50?

Sidana [21]

The answer is 11. You multiply 25 and 12.5 first. then once you find out how much money you get each week, you divide the 3437.5 by the number you got, which is 312.5. Divide 3437.5 by 312.5

Which Expression Can Be Used To Determine the nth term in the pattern below 20,25,30,35,40

maw [93]

Answer:

see explanation

Step-by-step explanation:

These are the terms of an arithmetic sequence with n th term

$a_{n}$ = a + (n - 1)d

where a is the first term and d the common difference

d = 25 - 20 = 30 - 25 = 5 and a = 20, hence

$a_{n}$ = 20 + 5(n - 1) = 20 + 5n - 5 = 5n + 15 ← n th term formula
