Distance
|a+bi| is the length of the vector from origin to (a,b).
Answer:
V=πr^2h
pi = 3.14
r = 2
r^2 = 4
h = 10
Multiply all the numbers to get the volume.
Or use the formula.
V = 3.14*4*10
V = 125.6 cubic inches
Answer:
Go to the left nine Units and go up two units
Step-by-step explanation:
Answer: The determinant of the coefficient matrix is -15 and x = 3, y = 4, z = 1.
Step-by-step explanation: The given system of linear equations is :

We are given to find the determinant of the coefficient matrix and to find the values of x, y and z.
The determinant of the co-efficient matrix is given by

Now, from equations (ii) and (iii), we have

Substituting the value of y and z from equations (iv) and (v) in equation (i), we get

From equations (iv) and (v), we get

Thus, the determinant of the coefficient matrix is -15 and x = 3, y = 4, z = 1.
