Answer:
30cm
Step-by-step explanation:
Assuming that the thickness of the books is 2cm (This is a reasonable assumption, as books are almost always longer and wider than they are thick, and assuming that the books are stacked flat on top of one another, faces up or down, and not sideways, the question becomes 'What is the height of 15 books stacked on top of one another, if each book is 2cm thick?' The answer to this question is 15*2 or 30.

Answer:
option C. Defined, 3 x 3
Step-by-step explanation:
The order of matrix A is 3 x 2 i.e 3 rows and 2 columns
The order of matrix B is 2 x 3 i.e. 2 rows and 3 columns
Two matrices can be multiplied if and only if the number of columns of 1st matrix is equal to the number of rows of 2nd matrix. Since the number of columns in matrix A is equal to the number of rows in matrix B, the product AB is defined.
The product AB will have number of rows equal to the rows of 1st matrix i.e. matrix A and number of columns equal to the columns of 2nd matrix i.e. matrix B.
So the order of AB will be 3 x 3 .
Therefore, the correct answer is option C. Defined 3 x 3

Step-by-step explanation:
h(t) = 2t 2 – 11t – 10 is the answer
Answer:
The slope of the line is 3.
The point on the line (1,4).
Step-by-step explanation:
Point Slope form is: 
'm' is the slope.
(x1, y1) is the point used to make the equation.
In the equation given, 3 replaces 'm', 4 replaces '<em>y1'</em> and 1 replaces '<u>x1'</u>.
y - <em>4</em> = 3 (x - <u>1</u>)
Therefore:
The slope of the line is 3.
The point on the line (1,4).
