Luna invested $8000 for 36 months at an interest rate of 4.8% per month. How much money will Luna have at the end of her investm
Degger [83]

Answer : $ 9, 152

Luna invested $8000 for 36 months at an interest rate of 4.8%

Let P = principal

T = time

r = rate

Using the simple interest,

\begin{gathered} I\text{ =}\frac{P\text{ x R x T}}{100} \\ P\text{ = \$8000} \\ r\text{ = 4.8\%} \\ t\text{ = 36 months} \\ 12\text{ months = 1 year} \\ 36\text{ months = x year} \\ \text{Cross multiply} \\ 12\cdot\text{ x = 1 x 36} \\ 12x\text{ = 36} \\ \text{Divide both sides by 12} \\ x\text{ = 36/12} \\ x\text{ = 3 years} \\ \text{Hence, t = 36 months = 3 years} \\ I\text{ = }\frac{8000\text{ x 3 x 4.8}}{100} \\ I\text{ = }\frac{115,\text{ 200}}{100} \\ I\text{ = \$1, 152} \end{gathered}

The total balance = Interest + principal

Balance = 1, 152 + 8000

Balance =$9, 152

The total money she will have at the end of the investment is $9, 152

Determine whether the given differential equation is separable. StartFraction dy Over dx EndFraction plus 2 sine (x minus y )equ
Natalka [10]

Answer:

dy/dx+2sin(x-y)=0

so whether the given equation is separable or not

dy/dx= -2sin(x-y)

the given equation is not separable because the argument inside the function is dependent on both x and y

even though we use the formula to open the sin(A-B) we would still get the function dependent on both x and y and the equation would get complicated so instead use any other method.

What is the inverse of the function f(x)​
tresset_1 [31]

Step-by-step explanation:

For the inverse function put f(x) =y.

Then exchange x by y and then again separate y. The new value of y is the inverse function of f(x).

You have not written the value of function in the question so I have given just tips to solve it.
