Answer:
When a matrix is multiplied by its inverse the result will be the identity matrix. If we multiply two matrix with the same size, the resulting matrix will have the same dimension.
Therefore, if we multiply the matrices X and Y we will get a 2x2 identity matrix, as follows:
![\left[\begin{array}{ccc}1&0\\0&1\\\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D1%260%5C%5C0%261%5C%5C%5Cend%7Barray%7D%5Cright%5D)
I only agree with the first student strategy of multiplying the area of the base with the height.
<h3 /><h3>Volume of a cylinder</h3>
A cylinder is made up of two circles at the top and the base.
The volume of the cylinder can be expressed as:
V = Bh
where
B is the base area
h is the height of the cylinder
V = πr²h
HEnce I only agree with the first student strategy of multiplying the area of the base with the height.

Answer:
35.06
Step-by-step explanation:
So you have to multiply 27.50 by 0.075 to find the sales tax.
2.0625 ≈ 2.06
If the tip is off the original price, you multiply 27.50 by 0.2.
5.5
The whole meal is 27.50 + 5.50 + 2.06 = 35.06
