Answer:

$2465

Step-by-step explanation:

Remember your annual interest rate formula (appreciation): A = P(1 + r)^t

Step 1: Solve for the first 2 years

1900(1 + 0.035)² = 2035.33

Step 2: Solve for the next 4 years

2035.33(1 + 0.049)^4 = 2464.54

Given: y" - 2y' = 6t + 5e^2t. Find the correct form to use for y_p if the equation is solved using Undetermined coefficients. Do
const2013 [10]

Answer:

y_p=A+Bt+Ce^{2t}

Step-by-step explanation:

Given: y'' - 2y' = 6t + 5e^{2t}.

we need to find the correct form for y_p if the equation is solve using undetermined coefficients.

A first order differential equation \frac{\mathrm{d} y}{\mathrm{d} x}=f\left ( x,y \right ) is said to be homogeneous if f(tx,ty)=f(x,y) for all t.

Consider homogeneous equation y''-2y'=0

Let y=e^{rt} be the solution .

We get (r^2-2r)e^{rt}=0

Since e^{rt}\neq 0, r^2-2r=0.

So, we get solution as y_c=c_1+c_2e^{2t}

As constant term and e^{2t} are already in the R.H.S of equation

y" - 2y' = 6t + 5e^{2t}, we can take y_p as y_p=A+Bt+Ce^{2t}

Is (-5,-5) a solution of y&gt; - 2x + 4?
valina [46]

Answer:

No

Step-by-step explanation:

Let's check by substituting -5 for y and -5 for x:

y > -2x + 4

-5 > -2 * (-5) + 4

-5 > 10 + 4

-5 > 14

However, we know that -5 is definitely not greater than 4, so we know that (-5, -5) is NOT a solution to the given inequality.

Hope this helps!
