Answer: X<-3

Step-by-step explanation: I got this becuase the open dot with the arrow point left means anything lower than -3, if it was closed (filled in) dot, it would be anything -3 and lower. But since it’s not, it’s just anything lower than -3.

Solve the differential equation. question is pictured with answer choices

Nimfa-mama [501]

Integrate both sides with respect to t :

∫ dy/dt dt = ∫ -12t ² dt

y(t) = -4t ³ + C

Use the initial condition to solve for C :

5 = -4•0³+ C

C = 5

y(t) = -4t ³ + 5

and the answer is D.

Alternatively, you can directly apply the fundamental theorem of calculus:

$\dfrac{\mathrm dy}{\mathrm dt}=-12t^2\implies y(t)=y(0)+\displaystyle\int_0^t -12u^2\,\mathrm du$

$\implies y(t)=5-4u^3\bigg|_0^t$

$\implies y(t)=5-4t^3$

$\huge\boxed{243}$

___________________________________________________________

$\boxed{Explanation}$

So, we have the following equation...

$3^2*3^3=(?)$

Remember $3^2$ and $3^3$ is the following...

$3^2=3*3\\3^3=3*3*3$

Therefore, $3*3=9\\3*3*3=27\\9*27=243$

So, your final answer is $\boxed{243}$ .
