Answer: The decimal 0.88888.... represented by the fraction \dfrac{8}{9}

Step-by-step explanation:

Since we have given that

0.888888....

So, Let x = 0.88888....=0.\bar{8} -----(1)

Now, multiply by 10 on both sides, we get that

10x=8.8888.....=8.\bar{8}----------(2)

Now, Subtracting (1) from (2), we get that

10x-x=8.\bar{8}-0.\bar{8}\\\\9x=8\\\\x=\dfrac{8}{9}

Hence, the decimal 0.88888.... represented by the fraction \dfrac{8}{9}

The answer is 38, because if you take away the 15 he bought afterwards (34-15) you get 19, and then since he sold half his collection you would double that (19×2) and that's 38.

What is the recursive formula of the geometric sequence?<br> 1, 5, 25, 125, 625, ...
Ilia_Sergeevich [38]

The recursive formula of the geometric sequence is given by option D; an = (1) × (5)^(n - 1) for n ≥ 1

<h3>How to determine recursive formula of a geometric sequence?</h3>

Given: 1, 5, 25, 125, 625, ...

  • first term, a = 1

  • Common ratio, r = 25/5

= 5

  • n = number of terms

an = a × r^(n - 1)

= 1 × 5^(n - 1)

an = (1) × (5)^(n - 1) for n ≥ 1

answer 16.99%

We are given this function:

8700 is the initial amount.

1.04 shows the change of original amount. This is decimal form of percentage. We need to transform it into regular percentage.

1.04 * 100% = 104%

Now we observe this number. If it is greater than 100% we have growth, if it is lower than 100% it is decay, and if it is equal to 100% than there is no change.

In our case this number is greater than 100% so we have growth. To determine the percentage rate we must substract 100% as it represents the original amount.

104% - 100% = 4%

This would be our solution if we don't have an exponent.

We have exponent so first step is to calculate the number and then we repeat the steps from above.

1,16985856 * 100% ≈ 116,99%

116.99% - 100% = 16.99%

So, final solution is growth of 16.99%
