Plz with this question asap which choice is it and steps to get the answer or explain why

D 20 *1.10 * 1.05

Step-by-step explanation:

We have 19.8 tons of wheat.  That is close to 20 tons

We increase by  9.8 percent. 9.8% is close to 10%

When we increase, that is 100% of what we had plus the increase, so we multiply by 100 +10% or 110%.  In decimal form that is 1.1

20 *1.10

Then the next year we increase by 5.1%.  That is close to 5%

We have 100% plus the 5% or 105%, which in decimal form is 1.05

We multiply what we had (20 *1.10) by 1.05

20 *1.10 * 1.05

This is the total amount we have

geometric series converge the common ratio r has magnitude less than one.

which is equivalent to

for the example we need

|2-x| < 1

-1 < 2-x   and 2-x < 1

x < 3 and x > 1

we can write that

answer: 1 < x < 3

1a. common ratio r=250/25=10 > 1     diverges

1b.   r=50/100=1/2 converges

when these converge they converge to

where a is the first term.

answer: 200

1c. r=-1   so it's not the case that |r| < 1.     diverges

2a. x is the common ratio so we converge when |x|< 1

2b.   r=-10x / -2 = 5x.

we converge when

|5x| < 1

|x| < 1/5

2c.   r=3-2x

-1 < 3-2x and 3-2x < 1

-4 < -2x and 2 < 2x

x < 2 and 1 < x

1 < x < 2

2d. [/tex] r=-48x^3/12 = 4x^3[/tex]

|4x^3| < 1

|x^3| < \frac 1 4

|x| < 4^{-1/3}
