Find a solution to dA/dt=-6A if A(0)=6. A(t)=

Delicious77 [7]

This equation is separable,

$\dfrac{dA}{dt} = -6A \implies \dfrac{dA}A = -6\,dt$

Integrate both sides and solve for $A$ :

$\displaystyle \int \frac{dA}A = -6 \int dt$

$\ln|A| = -6t + C$

$e^{\ln|A|} + e^{-6t+C}$

$\implies A(t) = Ce^{-6t}$

Solve for $C$ using the initial value.

$A(0) = 6 \implies 6 = Ce^0 \implies C=6$

Then the particular solution is

$\boxed{A(t) = 6e^{-6t}}$

Can someone pls help w finding the x and y intercepts of this? y=x^2-2x

AysviL [449]

Answer:

y-intercept is 0, x-intercept is 0 and 1

Step-by-step explanation:

For y-intercept, x=0 :

${ \tt{y = {(0)}^{2} - 2(0) }} \\ { \tt{y = 0}}$

For x-intercept, y=0 :

${ \tt{0 = {2x}^{2} - 2x }} \\ { \tt{2x(x - 1) = 0}} \\ { \tt{x = 0 \: \: and \: \: 1}}$
