Answer:
Step-by-step explanation:
Assuming the problem is asking you to factor out the formula, it can be done easily by finding a common number with the two givens.
4 goes into both 12 and 16 evenly, so we will use this to factor. But that's not all, we have the n-variable to worry about.
Look at the n-variable exponents in the problem, take the highest power that can go be subtracted from both and use that. We have a and
. Since 5 can't go into 3, we must use 3 to factor.
Our factoring variable will therefore be . Now, use this to simply divide and get the answer:
So how did we get this? For the whole numbers, we have to divide: (12/4, 16/4). Next, we have to minus the exponents since we are dividing.
When dividing the 12 and 4, minus the and
to get
. Get rid of the
term for the 16 and leave the 4. And there's your answer!
Answer:
y = 360(1.03)x
Step-by-step explanation:
F is the future worth, P is the present worth, I will be the interest rate, and n is the number of years.
The principal amount of the money = $360
Annual rate of interest = 3%
Thus, the amount after x years which is increased by 3%.
Since, this amount represented by y,
The required equation that represents the amount of money in Josiah’s account, y, after x years is,
This amount represented by y,
Therefore, the required equation that represents the amount of money in Josiah’s account, y, after x years is,
Hope this helps you!
Have a nice evening! ;)
