Answer:
4.5
Step-by-step explanation:
The equation of an area of a circle is A=πr² where r is the radius.
The radius is also half the diameter. So the radius of the quarter is 1.2
A=π(1.2)²
A=π(1.44)
A=4.52389
Vertex means top point of a tryangle
Move point b one unit down and move point a one unit up

Step-by-step explanation:
The zero matrix is the matrix which has m rows and n columns and all its elements are zero, for example:
This matrix has the property that, when applied to a vector, sends it to zero.
On the other hand, the multiplicative identity matrix is an square matrix that has 1's in its diagonal and zero's everywhere else.
This matrix has the property that when multiplied by another one, doesn't change the first matrix (leaves things the same way as they were, it's like multiplying by one)
For example, a 3 x 3 multiplicative identity matrix would be:
Answer:
48 in
Step-by-step explanation:
The length of the rug is 6 feet. We know this must account for 2 sides of the rug, so let's multiply 6 by 2.
6 × 2 = 12
Now subtract 12 from 20.
20 - 12 = 8
Now divide 8 by 2 to find the measurement of the remaining two sides.
8 ÷ 2 = 4.
The width of the rug is 4 feet. The question wants to find the width in inches, however. So multiply 4 by 12 because there are 12 inches in each foot.
4 × 12 = 48
The width of the rug is 48 inches.
