How to make a graph of an exponential function that shows exponential decay and has a y intercept of 2

Sliva [168]

Answer:

$f(x)=2e^{-kx}$

in a graph the x value at the y intercept is 0

$f(x)=Ae^{-kx}$ is a typical decay function

if x = 0 thus $e^{-kx}$ = 1

so at 0 the function value would be A

$f(x)=2e^{-kx}$

The line integral of xydx×x^2y^3dy where c is the triangle with points (0,0) (1,0) (1,2) using green's theorem

lyudmila [28]

If $\mathcal C$ is the boundary of the triangle $D$ , then by Green's theorem

$\displaystyle\int_{\mathcal C}xy\,\mathrm dx+x^2y^3\,\mathrm dy=\iint_D\left(\frac{\partial(x^2y^3)}{\partial x}-\frac{\partial(xy)}{\partial y}\right)\,\mathrm dA$
$=\displaystyle\int_{x=0}^{x=1}\int_{y=0}^{y=2x}(2xy^3-x)\,\mathrm dy\,\mathrm dx$
$=\displaystyle\int_{x=0}^{x=1}x\int_{y=0}^{y=2x}(2y^3-1)\,\mathrm dy\,\mathrm dx$
$=\displaystyle\int_{x=0}^{x=1}x(8x^4-2x)\,\mathrm dx=\frac23$

3/x-4=7/x

*cross multiply

3x=7 (x-4)

3x=7x-28

28=7x-3x

28=4x

x=7

Whats the common difference?

Stells [14]

Answer: The common difference is 8

Step-by-step explanation:

First Use the formula for the second to generate the first two numbers.

$u_{n}$ = 2^3n-2

Put in 1 for the first term and you will get 2 and the second term is 16 and to get from 2 to 16 you will multiply by 8.
