Answer:
18% decrease
Step-by-step explanation:
- 7,500 - 6,125 = $1,375
- Set up a proportion:
- Cross multiply, then divide: 1375 × 100 = 137500, 137500 ÷ 7500 = 18 1/3
- 18 1/3% rounded = 18%
- It went down, so it is a decrease

Answer:
The equation to represent the account balance in t years
![A\:=\:P\left(1\:+\:\frac{r}{n}\right)^{2t}](https://tex.z-dn.net/?f=A%5C%3A%3D%5C%3AP%5Cleft%281%5C%3A%2B%5C%3A%5Cfrac%7Br%7D%7Bn%7D%5Cright%29%5E%7B2t%7D)
Step-by-step explanation:
Given the compound interest equation
![A\:=\:P\left(1\:+\:\frac{r}{n}\right)^{nt}](https://tex.z-dn.net/?f=A%5C%3A%3D%5C%3AP%5Cleft%281%5C%3A%2B%5C%3A%5Cfrac%7Br%7D%7Bn%7D%5Cright%29%5E%7Bnt%7D)
here
A represents Accrued Amount (principal + interest)
P represents Principal Amount
I represent Interest Amount
r represents the Annual interest rate
t represents Time Involved in years
n represents the number of compounding periods per unit t
As we are given that the interest is compounded semi-annually
i.e. n = 2
so substituting n = 2 in the equation
![A\:=\:P\left(1\:+\:\frac{r}{n}\right)^{nt}](https://tex.z-dn.net/?f=A%5C%3A%3D%5C%3AP%5Cleft%281%5C%3A%2B%5C%3A%5Cfrac%7Br%7D%7Bn%7D%5Cright%29%5E%7Bnt%7D)
∵ n = 2
Thus, the equation to represent the account balance in t years
![A\:=\:P\left(1\:+\:\frac{r}{n}\right)^{2t}](https://tex.z-dn.net/?f=A%5C%3A%3D%5C%3AP%5Cleft%281%5C%3A%2B%5C%3A%5Cfrac%7Br%7D%7Bn%7D%5Cright%29%5E%7B2t%7D)
Answer:
The reason one must apply a force to a box in order for the box to move is to overcome the friction generated by the box against the plane the box is sitting.
The box at rest has zero friction against the surface on which it sits. Once a force is applied, a box's movement is resisted by the friction created from contact with the surface.
In order for the box to move, one must generate more force than is being generated by the friction of the surface onto the box, allowing the box to move.
Cheers.
