Answer:1/(3+x)=(1/3)

(1−(−x/3))

1/(3+x)=(1/3)1(1−(−x/3))

Use this fact that

1/(1−t)=

∑

∞

(∗)

1/(1−t)=∑0∞tn (∗)

where

|t|<1

. I mean take

t=−x/3

and...

Note that

|−t|=|t|<1

is the radius of convergence

Answer:

36 squared units

Step-by-step explanation:

So you can draw "made up lines" or I guess lines you draw yourself to create 2 rectangles. Check attachment.

The first rectangle is a square and has sides 3 and 3, so you get the area of 9.

The second, has sides 9 and 3, so you get the area of 27

Since you are trying to find the entire thing, you add 27 and 9 to get 36

After buying a pair of sneakers, Ben has $12 left which is 20% of what he started with. How much money did Ben have before he bo

Elis [28]

Answer: $60

Step-by-step explanation:

Given that:

Amount left after purchasing sneakers = $12

$12 is equivalent to 20% of the initial starting amount

Let starting amount = x

20% of x = $12

0.2x = $12

Divide through by 0.2

0.2x / 0.2 = $12 / 0.2

x = $60

Hence, starting amount before buying sneakers is $60

What is the area? Step by Step please

Damm [24]

If you are trying to find the surface area I believe it would be 3456 inches. You would do 24 X 24 to get 576 because the formula to get the area is Length times width. Then you would do 576 times 6 because the cube has 6 sides and you would multiply it by the number of sides because each would be the same, cubed are the same length all around. Hope this helped.

If the rate of inflation is 2.6% per year, the future price p(t) (in dollars) of a certain item can be modeled by the following

PilotLPTM [1.2K]

Answer:

The current price of the item is $600.

The price of the item 9 years from today will be of $756.

Step-by-step explanation:

Price of the item:

The price of the item, in dollars, after t years, is given by:

$p(t) = 600(1.026)^t$

Current price of the item

This is p(0). So

$p(0) = 600(1.026)^0 = 600$

The current price of the item is $600.

9 years from today.

This is p(9). So

$p(9) = 600(1.026)^9 = 756$

The price of the item 9 years from today will be of $756.
