The first term of this sequence is -20, and the common ratio is 11. Thus, the formula for the nth term is

a(n) = a(1)*(11)^(n-1), or (-20)*(11)^(n-1).

Thus, the 12th term is

a(12) = (-20)*(11)^(12-1) = -20(11)^11 = -20(2.85 times 10 to the 11th power.

or ... -5.71 times 10 to the 12th power.

PLEASE HELP ASAP! i don't get it
Natali5045456 [20]

Answer:

0 - 20

1 -22

5 - 30

10 - 40

15 - 50

20 - 60

Step-by-step explanation:

The initial amount this equation is 20 so that is why at 0 shirts its still 20 dollars for the set up fee and 2 dollars per shirt. Now that we have this information we can actually make a linear equation

y = 2x + 20

y = the total cost

x = the number of shirts

All you have to do next is plug in the number of shirts to get the total cost

Example:   2(1) + 20 = y

2 + 20 = y

22 = y

Meaning for 1 shirt it would be 22 dollars in total

Round 5984 to the nearest hundred.a) 5000 b) 5900 c) 5980 d) 5990 e) 6000
SpyIntel [72]
The answer would be E. because if the determining number (The number directly after the place being rounded to. The 8 in this case) is greater than five, you round up and drop the numbers after the place being rounded to (The hundredth's place), if it's less, the number in the place being rounded to stays the same, but you still drop the numbers after it.
