Answer: 6

Step-by-step explanation:

For the math problem, "45 minus what equals 39?", we can make it into an algebra equation as follows:

45 - X = 39

Then, we solve for X. To solve for X, we first subtract 45 from both sides:

45 - 45 - X = 39 - 45

-X = -6

Next, you multiply each side by -1 to remove the minus from the X:

-X(-1) = -6(-1)

X = 6

Therefore, the answer to "45 minus what equals 39?" is 6 as illustrated below:

45 - 6 = 39

Answer:

Hello. The answer is 6.

Step-by-step explanation:

You basically have to subtract. 45 - (?) = 39.

45 - 6 will give you = 39.

I'm surprised even an adult doesn't know that?

Find the solution r(t)r(t) of the differential equation with the given initial condition: r′(t)=⟨sin9t,sin6t,9t⟩,r(0)=⟨4,6,3⟩

klemol [59]

$\mathbf r'(t)=\langle\sin9t,\sin6t,9t\rangle$

$\mathbf r(t)=\displaystyle\int\mathbf r'(t)\,\mathrm dt$

$\mathbf r(t)=\left\langle\displaystyle\int\sin9t\,\mathrm dt,\int\sin6t\,\mathrm dt,\int9t\,\mathrm dt\right\rangle$

$\displaystyle\int\sin9t\,\mathrm dt=\frac19\cos9t+C_1$

$\displaystyle\int\sin6t\,\mathrm dt=\frac16\cos6t+C_2$

$\displaystyle\int9t\,\mathrm dt=\frac92t^2+C_3$

With the initial condition $\mathbf r(0)=\langle4,6,3\rangle$ , we find

$\dfrac19\cos0+C_1=4\implies C_1=\dfrac{35}9$

$\dfrac16\cos0+C_2=6\implies C_2=\dfrac{35}6$

$\dfrac92\cdot0^2+C_3=3\implies C_3=3$

So the particular solution to the IVP is

$\mathbf r(t)=\left\langle\dfrac19\cos9t+\dfrac{35}9,\dfrac16\cos6t+\dfrac{35}6,\dfrac92t^2+3\right\rangle$
