Answer:

B) Jump discontinuity at x=-2; infinite discontinuity as x=0

Step-by-step explanation:

In the given piecewise function, we see that there is a jump discontinuity at x=-2. Also, there's an infinite discontinuity at x=0 since as x approaches 0 from the left side, the left-side limit goes to infinity. Therefore, B is correct.

Answer:

see the explanation

Step-by-step explanation:

Let

L ---> the length of rectangle in cm

W ---> the width of rectangle in cm

The area of rectangle is

$A=LW$

$A=991\ cm^2$

$991=LW$ ---> equation A

we know that

Prime numbers only have factors of 1 and themselves.

So a rectangle with an area of 991 cm² can only be either

$W=1\ cm, L=991\ cm$ or $L=1\ cm, W=991\ cm$

How do I find the percent of budget?

ch4aika [34]

Answer:

First, subtract the budgeted amount from the actual expense. If this expense was over budget, then the result will be positive.

Next, divide that number by the original budgeted amount and then multiply the result by 100 to get the percentage over budget. If your expenses were lower than your budgeted amount, then this number will be negative, describing the percentage under budget.
