Answer:
use identity (a - b) ^3 = a^3 - b^3 - 3ab (a - b)
here, a = x ^2
b = -1
= (x^2)^3 - (-1)^3 - 3 * x ^2 * -1 ( x^2 - (-1) )
x^6+ 3 x^2 ( x ^2 + 1)
I think this is the answer
Answer:
A, B, E
Step-by-step explanation:
Three or more points are said to be collinear, if they lie on a single straight line
Answer:
A least-squares solution of is a vector such that for all in .
C. The statement is true because the general least-squares problem attempts to find an that maximizes .
Step-by-step explanation:
The above statement is actually the one that validates the least-square solution statement.
If there is a decrease on y then that’s the answer
We are given:
parent function y = cot (x) which is vertically compressed to produce y = a cot(x) with no reflections.
The graph of the cotangent function is opposite of tangent function. You can observe that if the function will be vertically compressed it will shift towards zero but not less than zero, so the value of a is best described as d a>1.
