tangare [24]2 years ago
3 0

Answer:

D

Step-by-step explanation:

So we want to figure out the measure of angle ?.

We already know that sides <em>opposite</em> and <em>adjacent</em> to the angle.

Therefore, we need to use tangent. Recall that tangent:

\tan(?)=opp/adj

Substitute 34 for the opposite and 48 for the adjacent:

\tan(?)=34/48

Divide (approximately):

\tan(?)=0.71

Take the inverse tangent of both sides:

?=\tan^{-1}(0.71)

So, our answer is D

And we're done!

Find the general solution to 3y′′+12y=0. Give your answer as y=... . In your answer, use c1 and c2 to denote arbitrary constants
lozanna [386]

Answer:

y(x)=c_1e^{2ix}+c_2e^{-2ix}

Step-by-step explanation:

You have the following differential equation:

3y''+12y=0     (1)

In order to find the solution to the equation, you can use the method of the characteristic polynomial.

The characteristic polynomial of the given differential equation is:

3m^2+12=0\\\\m^2=-\frac{12}{3}=-4\\\\m_{1,2}=\pm2\sqrt{-1}=\pm2i

The solution of the differential equation is:

y(x)=c_1e^{m_1x}+c_2e^{m_2x}   (2)

where m1 and m2 are the roots of the characteristic polynomial.

You replace the values obtained for m1 and m2 in the equation (2). Then, the solution to the differential equation is:

y(x)=c_1e^{2ix}+c_2e^{-2ix}

410.3ft^3. is correct





volume of the sphere with 3ft radius :
\frac{4  \times  \pi \times 3 \times 3 \times 3}{3}  = 113




volume of the sphere with 5ft radius:
\frac{4 \times \pi \times 5 \times 5 \times 5}{3}  = \frac{1570}{3}   = 523.3



difference
523.3 - 113 = 410.3





good luck
