Answer:
There would be $3,450.14 by the end of 4 months
There would be $4,623.78 by the end of 7 years.
Step-by-step explanation:
We are given the following in the question:
P = 3,400$
r = 4.4% = 0.044
Compounded monthly
Formula:
The compound interest is given by:

where A is the amount, p is the principal, r is the interest rate, t is the time in years and n is the nature of compound interest.
a) 4 months

There would be $3,450.14 by the end of 4 months.
b) 7 years
t = 7

There would be $4,623.78 by the end of 7 years.
Answer:
f(-10) = 6
Step-by-step explanation:
f(x) is simply just the name of the function. x will be your dependent variable that you'll use to plug into the equation.
Since they want you to find f(-10), you'll then plug -10 in where x was and solve.
f(-10) = -2((-10)+7)
f(-10) = -2(-3)
f(-10) = 6
First, it is important to understand that any equation that is x=some number is just a vertical line that hits the x-axis at the given number. For example, x=-2 would be a vertical line hitting the x-axis at -2. Therefore, the line we are trying to identify would also be vertical (and have the form x=some number) because we know the lines are parallel. Then, since we're given the point (-5,4), we know the line needs to hit the x-axis at -5, therefore the equation would be x=-5.
I hope this helps.
Question:
Solution:
Let the following equation:
![\sqrt[]{12-x}=\text{ x}](https://tex.z-dn.net/?f=%5Csqrt%5B%5D%7B12-x%7D%3D%5Ctext%7B%20x%7D)
this is equivalent to:
![(\sqrt[]{12-x})^2=x^2](https://tex.z-dn.net/?f=%28%5Csqrt%5B%5D%7B12-x%7D%29%5E2%3Dx%5E2)
this is equivalent to:

this is equivalent to:

thus, we can conclude that
x= 3.
