In three dimensions, the cross product of two vectors is defined as shown below

Then, solving the determinant

In our case,

Where we used the formula for AxB to calculate ixj.
Finally,

Thus, (i+j)x(ixj)=i-j
Answer:
y = (x - 2)(x + 4)(x - 1)
Step-by-step explanation:
Given the zeros of a function say x = a and x = b, then
The factors are (x - a) and (x - b) and
y = (x - a)(x - b)
Given the zeros are x = 2, x = - 4, x = 1, then
the factors are (x - 2), (x - (- 4)) and (x - 1), that is
(x - 2), (x + 4), (x - 1) , thus
y = (x - 2)(x + 4)(x - 1)
Answer:
20.25
Step-by-step explanation:
45x.40=20.25
Answer:
n=11
Step-by-step explanation:
Solve for n by simplifying both sides of the equation, then isolating the variable.
43.
The coefficient of something is the numerical value in that term. For example, if we have 4x. The coefficient is 4.
