Step-by-step explanation:
Answer:
the additive inverse of -5=0
the multiplicative inverse of -5=1
Answer:
The balance will be $7,164.31.
Step-by-step explanation:
The compound interest formula is given by:
![A = P(1 + \frac{r}{n})^{nt}](https://tex.z-dn.net/?f=A%20%3D%20P%281%20%2B%20%5Cfrac%7Br%7D%7Bn%7D%29%5E%7Bnt%7D)
Where A is the amount of money, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per unit t and t is the time the money is invested or borrowed for.
In this problem, we have that:
![P = 6000, r = 0.06](https://tex.z-dn.net/?f=P%20%3D%206000%2C%20r%20%3D%200.06)
Semi-annually is twice a year, so ![n = 2](https://tex.z-dn.net/?f=n%20%3D%202)
We want to find A when ![t = 3](https://tex.z-dn.net/?f=t%20%3D%203)
![A = P(1 + \frac{r}{n})^{nt}](https://tex.z-dn.net/?f=A%20%3D%20P%281%20%2B%20%5Cfrac%7Br%7D%7Bn%7D%29%5E%7Bnt%7D)
![A = 6000(1 + \frac{0.06}{2})^{2*3}](https://tex.z-dn.net/?f=A%20%3D%206000%281%20%2B%20%5Cfrac%7B0.06%7D%7B2%7D%29%5E%7B2%2A3%7D)
![A = 7164.31](https://tex.z-dn.net/?f=A%20%3D%207164.31)
The balance will be $7,164.31.
.5 means half. 12 x 2 is 24. so, your equation would be x/2=12
d(n) = 6 - 4(n - 1)
Plug 5 into the equation for n.
d(5) = 6 - 4(5 - 1)
Subtract 1 from 5
d(5) = 6 - 4(4)
Multiply 4 by 4
d(5) = 6 - 16
Simplify the right side
d(5) = -10
The fifth term in the sequence is -10
