A pair of parallel lines is cut by a transversal, as shown below.

MA_775_DIABLO [31]

Answer:

$x=45\degree$

Step-by-step explanation:

In the diagram, the measure of the $(x+30\degree)$ angle is equal to the $75\degree$ angle.

These two angles are alternate angles.

We therefore set up the following equation and solve for x.

$x+30\degree =75\degree$

$\Rightarrow x =75\degree-30\degree$

$\Rightarrow x =45\degree$

Assuming you mean

$5\sin t\dfrac{\mathrm dy}{\mathrm dt}+5y\cos t=\cos t\sin^2t$

This ODE is linear in $y$ , and you can already contract the left hand side as the derivative of a product:

$\dfrac{\mathrm d}{\mathrm dt}\left[5y\sin t\right]=\cos t\sin^2t$

Integrating both sides with respect to $t$ yields

$5y\sin t=\displaystyle\int\cos t\sin^2t\,\mathrm dt$
$5y\sin t=\dfrac13\sin^3t+C$
$y=\dfrac1{15}\sin^2t+C\csc t$

Given that $y\left(\dfrac\pi2\right)=9$ , we have

$9=\dfrac1{15}\sin^2\dfrac\pi2+C\csc\dfrac\pi2$
$9=\dfrac1{15}+C$
$C=\dfrac{134}{15}$

so that the particular solution over the interval is

$y=\dfrac1{15}\sin^2t+\dfrac{134}{15}\csc t$

Kevin states, “All lines are composed of infinitely many line segments.” Is he correct? Why or why not?

Lemur [1.5K]

Remark.

It's true. A line segment has a finite length. A line is infinitely long. It takes a lot of something that is finite to cover something that is infinite.

________ Suppose this is a part of a line. Just a part mind you.

.................... these are line segments. How many segments will it take to cover a line if you keep on extending the line to the line's "full" length?
