Find the perimeter and area. (Plz help with this problem)

The first step to solving this problem is to find the area and circumference of the half circle using these equations:
d/\frac{1}{2} =r r*\pi=C and C/\frac{1}{2}= a
d= diameter
r= radius
C= circumference
a= answer

So the the "d" of the half circle is 10, and half of 10 is
r=5 . Because we are solving for only half of the circle this is what happens:
5*\pi =15.71
15.71*\frac{1}{2} =7.86
Now we just add the other sides together: 10+19+19+7.86=55.86m
The Perimeter is 55.86

Now for the area we must use a similar equation for the half circle: Area=\pi r^2
5^2=2525*\pi =78.54

This is the area of the whole circle so we have to divide 78.54 by half to get our answer, which is 39.27

10*19=190 This is the area of the rectangle
190+ 39.27=229.27 Is the area of the whole shape

Perimeter= 55.86
Area= 229.27

Since the horizontal lines are parallel, we know from similar figures that the ratios are proportional.
when
24/x=36/12, or 

24    36
--   = ---
x      12

We divide the product of diagonals with numbers (24*12) by the number across from x (36) to get the value of x, i.e.
x=(24*12)/36=288/36=8

Helpp!!!Evaluate the piecewise function at the indicated values from the domain:
SCORPION-xisa [38]

Answer:

f(-1) = -1 . . . . matches the last selection

Step-by-step explanation:

When evaluating piecewise functions, the first step is to determine the applicable piece. The argument -1 is in the range of the middle definition, (-2, 1). So, the function value is ...

... (-1)³ = -1

What is x to the second power -2x-8=0?​
Ipatiy [6.2K]

X would be -2 to the second power

-2*-2^2 would give you 8 and 8-8 gives you 0

Is this a function?<br> ignore the graph above the one with the dots lol
Evgen [1.6K]

Answer:

No.

Step-by-step explanation:

Use a vertical line test.

Vertical line test: If you can draw a vertical line and it <u>does not</u> cross two points in the line, then it is a function.

So, we draw a line.

Draw it through 9,0

It intercepts two points so No. This is not a function.

Hope this helps plz hit the crown :D
