Answer:
Yes!
Step-by-step explanation:
I know this from having been a bank teller. But let's examine the math.
Any two digit number can be written as 10x + y.
Reverse the digits would give you
10y + x
Subtract to find the difference.
10x + y - (10y + x)
10x + y - 10y - x
10x - x - 10y + y
9x - 9y
9(x - y)
Yes, it has 9 as a factor, so it is a multiple of 9.
Reflecting a point on the x axis is the same as performing the following transformation:
T -> (x, -y)
Applying the transformation we have
P (-3.2) ---> (x, -y) ----> p (-3, -2)
Therefore, the new point is
p (-3, -2)
answer
p (-3, -2)
Answer:

to the nearest tenth
Step-by-step explanation:
find the area of the semi circle

find area of the whole shape

then subtract both areas to get shaded area

The only thing you can do here is to try to simplify, so I'll assume that's what you want to do.

The numerator is a difference of squares, so it's easy to factorize:

In the denominator, we factorize by grouping:

So we have
