Answer:
$311.20
Step-by-step explanation:
Here we are required to use the Compound interest formula for finding the Amount at the end of 9th year
The formula is given as
![A=P(1+\frac{r}{n})^{tn}](https://tex.z-dn.net/?f=A%3DP%281%2B%5Cfrac%7Br%7D%7Bn%7D%29%5E%7Btn%7D)
Where ,
A is the final amount
P is the initial amount = $200
r is the rate of interest = 5% annual = 0.05
n is the frequency of compounding in a year ( Here it is compounding monthly) = 12
t is the time period = 9
Now we substitute all these values in the formula and solve for A
![A=200(1+\frac{0.05}{12})^{9\times 12}](https://tex.z-dn.net/?f=A%3D200%281%2B%5Cfrac%7B0.05%7D%7B12%7D%29%5E%7B9%5Ctimes%2012%7D)
![A=200(1+0.00416)^{108}](https://tex.z-dn.net/?f=A%3D200%281%2B0.00416%29%5E%7B108%7D)
![A=200(1.00416)^{108}](https://tex.z-dn.net/?f=A%3D200%281.00416%29%5E%7B108%7D)
![A=200 \times 1.556](https://tex.z-dn.net/?f=A%3D200%20%5Ctimes%201.556)
![A=311.20](https://tex.z-dn.net/?f=A%3D311.20)
Hence the amount after 9 years will be $311.20
Answer:
11.2 or 56/5 or 11 1/5
Step-by-step explanation:
Answer:
no its positive
Step-by-step explanation:
negative X negative = positive
Negative x positive = negative
positive x positive = positive
C: y= 6
Since they are varying inversely, as one gets larger the other gets smaller and vice-versa.
Since when y=3 when x=4.....
When x gets divided by two y would get multiplied by two instead
So y=6 when x=2
Answer:
<h3>x > π/4</h3>
Step-by-step explanation:
Given the inequality expression
sin(x)>cos(x)
Divide both sides by cos(x)
sin(x)/cos(x)>cos(x)/cos(x)
tan(x) > 1
x > tan⁻¹1
x > 45⁰
x > π/4
Hence the required solution is x > π/4
