Find the interest earned and the future value of an annuity with quarterly payments of $600 for 8 years into an account that pay

iVinArrow [24]

Answer:

interest earned= 292.878

the future value of an annuity= 892.878

Step-by-step explanation:

Given Data:

Interest rate= 5%

time,t = 8 years

Quarterly payment, P= 600

n= 4 as quarterly

At the end of 8 years, final investment A= ?

As per the interest formula

A= P(1+r/n)^nt

= 600(1+0.05/4)^32

= 892.878

Interest earned = A-P

= 892.878-600

= 292.878 !

What is the equation of the line? Graph of a line in the coordinate plane through the origin and the point begin ordered pair 1

Margarita [4]

Here the line passes through (0,0) and (1,3).

First we need to find the slope , and for that we need to use the following formula

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

On substituting the values from the point, we will get

$m=\frac{3-0}{1-0}=3$

Now we will use slope intercept form, which is

$y = mx+ b$

Where m is the slope and b is the y intercept

And on substituting the values of x and y from the point (1,3) and slope, m = 3, we will get

$3 = 3(1)+b$

$3=3+b$

b =0

Substituting the values of m and b in the slope intercept form, we will get

$y= 3x$

Find x, and then any unknown angles in the quadrilateral.<br> x= ?

sertanlavr [38]

Answer:

x=65

other angle= 165

Step-by-step explanation:

quadrilaterals always have a total of 360 degrees

because of this you can set up an equation and solve

360=90+40+x+(4x-95)

360=130+5x-95

360=35+5x

325=5x

65=x

plug this in to find missing angle

4(65)-95=165

Find the solution of the given initial value problems in explicit form. Determine the interval where the solutions are defined.

natali 33 [55]

Answer:

The solution of the given initial value problems in explicit form is $y=x-x^2-2$ and the solutions are defined for all real numbers.

Step-by-step explanation:

The given differential equation is

$y'=1-2x$

It can be written as

$\frac{dy}{dx}=1-2x$

Use variable separable method to solve this differential equation.

$dy=(1-2x)dx$

Integrate both the sides.

$\int dy=\int (1-2x)dx$

$y=x-2(\frac{x^2}{2})+C$ $[\because \int x^n=\frac{x^{n+1}}{n+1}]$

$y=x-x^2+C$ ... (1)

It is given that y(1) = -2. Substitute x=1 and y=-2 to find the value of C.

$-2=1-(1)^2+C$

$-2=1-1+C$

$-2=C$

The value of C is -2. Substitute C=-2 in equation (1).

$y=x-x^2-2$

Therefore the solution of the given initial value problems in explicit form is $y=x-x^2-2$ .

The solution is quadratic function, so it is defined for all real values.

Therefore the solutions are defined for all real numbers.
