Initial value problems dy/dx+2y=3. Y(0)=1
Pavel [41]

The initial value equation is y = \frac 12(3 - e^{-2x})

<h3>How to solve the initial value?</h3>

The equation is given as:

\frac{dy}{dx} +2y = 3

Where

Y(0) = 1

Subtract 2y from both sides in the equation

\frac{dy}{dx}  = -2y + 3

Rewrite as:

\frac{dy}{-2y + 3}  =  dx

Integrate both sides of the equation

-\frac 12\ln|-2y + 3| = x + C_o

Multiply through by -2

\ln|-2y + 3| = -2x + C_1

Take the exponent of both sides

-2y + 3 = Ce^{-2x

Next, we solve for C under the initial condition Y(0) = 1.

This gives

-2(1) + 3 = Ce^{-2 * 0

Evaluate

-2 + 3 = C

Solve for C

C = 1

Substitute C = 1 in -2y + 3 = Ce^{-2x

-2y + 3 = e^{-2x

Next, we solve for y

y = \frac 12(3 - e^{-2x})

Hence, the initial value equation is y = \frac 12(3 - e^{-2x})

Length of rectangle is 4 m less than 3 times its breadth. If the perimeter of rectangle is 32 m. Find its length and breadth B=1
timama [110]

Answer:

Length = 11m and the Breath = 4m

Step-by-step explanation:

L = 3B - 4

p = 32m

2( L + B ) = 32

L + B = 32/2

L + B = 16

(3B - 4) + B = 16

3B - 4 + B = 16

4B - 4 = 16

4B = 16 + 4

4B = 20

B = 20/4 = 5m

B = 5m

L = 3B - 4

L = 3(5) - 4

L = 15 - 4

L = 11m

Which is bigger, one fourth of 16 or one third of 24?
sesenic [268]
One third of 24 because 3 is a whole number smaller than 4 so the answer would be 3/24 not 4/16.
