Answer:

Its the first option.

Step-by-step explanation:

The area of the whole circles is pi r^2 and the total angle in the circle = 360 degrees. So the shaded area is a fraction of the total area = measure of central angle in the sector / 360.

Describe the piecewise function below by evaluating the function for given values of the domain

tekilochka [14]

We have a piecewise function.
Therefore, to find the function, we must evaluate each domain separately.
We have then:

For $x \leq -2$ :
The function for this domain is:
$y = -3
$

For $-2 \ \textless \ x \leq 2$ :
The function for this domain is:
$y = mx + b
$
Where,
$b = -3

 m = (y2 - y1) / (x2 - x1)

 m = (1 - (-7)) / (2 - (-2))$
$m = (1 + 7) / (2 + 2)

 m = 8/4

 m = 2$
Substituting:
$y = 2x - 3
$

For $x\ \textgreater \ 2$ :
The function for this domain is:
$y = 5$

5. At a picture frame shop you order a $52 picture frame. You have a $40 gift certificate and a

svetoff [14.1K]

Do the 11% off first.

11% of 52$ is 46.38$, then you take $40 off and your total is only $6.38

if you do -40$ first then you have $12 left and 11% off that is $10.68.

Can a triangle have angle measures as 140,43, and 7

Mariulka [41]

The angles in a triangle always add up to exactly 180 degrees. To see if this can be a triangle, add up the given angle measures. If the sum is not 180, then it cannot be a triangle.

140+43+7=190

A triangle CANNOT have the angles measures as 140, 43, and 7.

Hope this helps!!
