A principal of $3500 is invested at 3.75% interest, compounded annually. How much will the investment be worth after 12 years? R

Thepotemich [5.8K]

Use the compound amount formula:

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

Here,

A = $3500*(1+0.0375/12)^(12*12) = $5485.24

It’s c

8 squared is 64
If you multiply that by 4 you will get 256 pi
You will not have to approximate it.

Find a homogeneous linear differential equation with constant coefficients whose general solution is given by

frez [133]

Answer:

$y" + 2y' + 2y = 0$

Step-by-step explanation:

Given

$y=c_1e^{-x}cosx+c_2e^{-x}sinx$

Required

Determine a homogeneous linear differential equation

Rewrite the expression as:

$y=c_1e^{\alpha x}cos(\beta x)+c_2e^{\alpha x}sin(\beta x)$

Where

$\alpha = -1$ and $\beta = 1$

For a homogeneous linear differential equation, the repeated value m is given as:

$m = \alpha \± \beta i$

Substitute values for $\alpha$ and $\beta$

$m = -1 \± 1*i$

$m = -1 \± i$

Add 1 to both sides

$m +1= 1 -1 \± i$

$m +1= \± i$

Square both sides

$(m +1)^2= (\± i)^2$

$m^2 + m + m + 1 = i^2$

$m^2 + 2m + 1 = i^2$

In complex numbers:

$i^2 = -1$

So, the expression becomes:

$m^2 + 2m + 1 = -1$

Add 1 to both sides

$m^2 + 2m + 1 +1= -1+1$

$m^2 + 2m + 2= 0$

This corresponds to the homogeneous linear differential equation

$y" + 2y' + 2y = 0$

I need this done super fast help!!!! And it has 7 parts so step by step please

bagirrra123 [75]

Answer:

177 and 178

Step-by-step explanation:

First, the expression for the 2nd mile marker is x+1.

Now, you add x and x + 1 together to get 2x + 1

Next, make 2x + 1 equal to 355

Now subtract 1 and then divide by two on both sides to get x = 177.

This means that the first mile marker is 177 and the next is 178.
