Answer:

Jump discontinuity at x = -2 & infinite discontinuity at x = 0.

Step-by-step explanation:

Hi again,

In this example, we see that there is a jump discontinuity at x = -2 because the line hypothetically "jumps" from y = 2 to y = 0. (just a way to remember these terms)

In addition, there is an infinite discontinuity at x = 0 because the green function will become infinitely close to x = 0 but never crosses nor touches it.

Hope this explanation was helpful. Cheers.

How do I solve the equation in an interval from 0 to 2π ? 9 cos 2t = 6

Ivahew [28]

$9\cos(2t)=6\implies\cos(2t)=\dfrac23$

Using the fact that cos is 2π-periodic, we have

$\cos(2t)=\dfrac23\implies2t=\cos^{-1}\left(\dfrac23\right)+2n\pi$

That is, $\cos(\theta+2n\pi)=\cos\theta$ for any $\theta$ and integer $n$ .

$\implies t=\dfrac12\cos^{-1}\left(\dfrac23\right)+n\pi$

We get 2 solutions in the interval [0, 2π] for $n=0$ and $n=1$ ,

$t=\dfrac12\cos^{-1}\left(\dfrac23\right)\text{ and }t=\dfrac12\cos^{-1}\left(\dfrac23\right)+\pi$

Answer:

First one.

Step-by-step explanation:

0.3/3=0.1 ==> 0.1$ per meter

0.77/7 ==> 0.11$ per meter

The first option is cheaper, therefore better to buy if you agree with "the cheaper. the better".
