Solve the decay equation y' = -ky using the integrating factors method. Show work

Alex777 [14]

Answer:

$y=\frac{c}{e^{kx}}$

Step-by-step explanation:

$\frac{\mathrm{d} y}{\mathrm{d} x} =-ky$

$\frac{\mathrm{d} y}{\mathrm{d} x} +ky=0$

comparing with equation

$\frac{\mathrm{d} y}{\mathrm{d} x} + Py=Q(x)$

$I.F.= e^{\int P dx}$

$I.F.= e^{\int k dx}$

$I.F.= e^{kx}$

$y=\frac{1}{I.F.} ( \int {Q(x)} dx +c)$

$y=\frac{1}{e^{kx}} ( \int {0} dx +c)$

$y=\frac{c}{e^{kx}}$

7th grade sac practice problems look at the triangular prism below. each triangular face of the prism has a base of 3 centimeter

xxMikexx [17]

Answer:

72cm³

Step-by-step explanation:

Base of the triangular face =3 cm.

Height of the triangular face = 4 cm.

Length of the prism = 12 cm.

Volume of a Prism= Base Area X. length

The base of a triangle prism is a triangle, therefore:

Volume of a Triangular Prism= ½bh X Length

=½ X 3 X 4 X 12

=½ X 144

=72cm³

Volume of the triangular Prism= 72cm³

What is the slope and the y-intercept of the line on the graph below?

miss Akunina [59]

Well, since we do not know the line, the basic slope formula is Y = mX + B
So look at the line and see where is crosses the y axis (the vertical) and that is your B in the formula or the "Y-intercept" as an example I will used the number 1. Then on your line pick two points, I will use the points (4,4) and (1,2) as an example. To find your slope take the Ys in those points (the second number) and subtract them 4 - 2 = 2. Then subtract the Xs (the first numbers) 4 - 1 = 3. Lastly, take the 2 and divide it by the 3 (yes it can be a fraction) and that is your slope. So the entire answer with my examples would be Y = $\frac{2}{3}$ x + 1 with 1 being my y-intercept and 2/3 being my slope
