Answer: 3x + 2
Step-by-step explanation:
Using an exponential function, it is found that the amounts deposited at the end of each month are given by:
- At the end of the first month, she deposits $110.
- At the end of the second month, she deposits $121.
- At the end of the third month, she deposits $133.1.
- At the end of the fourth month, she deposits $146.41.
<h3>What is an exponential function?</h3>
An increasing exponential function is modeled by:
In which:
- A(0) is the initial value.
- r is the growth rate, as a decimal.
In this problem, we have that A(0) = 100, r = 0.1, hence the equation for the amount deposited after t months is:
Then, for each of the first four months:

Answer:
Thus the mass of copper in solid form is m = 9860 kg
Notice that:
7=16-9
2=9-7
5=7-2
the next term would be: 2-5=-3
so each term of the sequence is equal to its previous term, subtracted from the second previous term:
Also, in order to describe the formula, we need to express the 2 first terms, 1 is not enough.
The recursive formula is:
To find a perfect square we want the equation to look like (y - 8)(y-8) because
the two numbers that add up to -16 and multiply into 64. are -8, -8. -8^2 is 64.
