Answer:
![f(n) = \frac{1250}{11}(11)^n](https://tex.z-dn.net/?f=f%28n%29%20%3D%20%5Cfrac%7B1250%7D%7B11%7D%2811%29%5En)
Step-by-step explanation:
Given
![f(n) = 1250(11)^{n-1}](https://tex.z-dn.net/?f=f%28n%29%20%3D%201250%2811%29%5E%7Bn-1%7D)
Required
Write as exponential function
An exponential function is represented as:
![f(n) = ab^n](https://tex.z-dn.net/?f=f%28n%29%20%3D%20ab%5En)
![f(n) = 1250(11)^{n-1}](https://tex.z-dn.net/?f=f%28n%29%20%3D%201250%2811%29%5E%7Bn-1%7D)
Apply law of indices
![f(n) = \frac{1250(11)^n}{11}](https://tex.z-dn.net/?f=f%28n%29%20%3D%20%5Cfrac%7B1250%2811%29%5En%7D%7B11%7D)
![f(n) = \frac{1250}{11}(11)^n](https://tex.z-dn.net/?f=f%28n%29%20%3D%20%5Cfrac%7B1250%7D%7B11%7D%2811%29%5En)
<em>The above represents the exponential function</em>
Answer:
2172 is the total cost
Cost for tiles: 1800
cost of paint: 372
Find the surface area of the wall without floor:(for cost of paint)
40 x 15 + 40x3x2 + 15x3x2 = 600 + 240 + 90 = 930
Cost: 930/25 x 10 = 372
Find area of floor:(to find cost of tiles)
40 x 15 = 600m^2
cost: 600 x 3 = 1800pounds
add them if needed
Hope this helps
Good Luck
Considering that the powers of 7 follow a pattern, it is found that the last two digits of
are 43.
<h3>What is the powers of 7 pattern?</h3>
The last two digits of a power of 7 will always follow the following pattern: {07, 49, 43, 01}, which means that, for
, we have to look at the remainder of the division by 4:
- If the remainder is of 1, the last two digits are 07.
- If the remainder is of 2, the last two digits are 49.
- If the remainder is of 3, the last two digits are 43.
- If the remainder is of 0, the last two digits are 01.
In this problem, we have that n = 1867, and the remainder of the division of 1867 by 4 is of 3, hence the last two digits of
are 43.

Step-by-step explanation:
First of all, we need to Reduce or Simplify the fractions to do this problem.
18/56 simplified is 9/28.
12/56 simplified is 3/14.
So our equation now is 9/24 divided by 3/14. (You do not need common denominators for dividing fractions.)
To find the answer of this problem, we follow a formula, Keep, Change, Flip.
You keep it the same.
Change the division sign to multiplication sign.
Then Flip the second fraction's numerator and denominator.
For example: 3/8, flipped is 8/3.
For example: 14/6, flipped is 6/14.
So we keep the problem the same:
9/28 / 3/14.
Change the division sign to multiplication sign:
9/28 x 3/14.
Then Flip the second fraction:
9/28 x 14/3 = ?
9 x 14 = 126,
28 x 3 =84.
Our answer is 126/84.
We should reduce our answer to get the proper results.
Reduced is:
3/2
Our final answer is 3/2.
Good luck on testing!
