Answer:
1. (2x^2+x-1)
Step-by-step explanation:
expanding (2x^2-1)^2. multiplying (x-2) (1-2x)
= 4x^2-4x+1. = x-2x^2-2+4x
= -2x^2+5x-2
(4x^2-4x+1-2x^2+5x-2)
=2x^2+x-1
Answer:
For this problem first we need to figure out the covariance of the JP morgan
and its value is 24
Second we find expected return and standard deviation whose values are 9% and 34.98
<span>ax + by + c = 0
by = - ax - c
y = -a/b (x) - c/b
so slope = </span>-a/b
answer
-a/b
The algebraic property is called here commutativity :
<span>x ⋅ y ⋅ z = y ⋅ x ⋅ z
| ÷z (We divide by z)
</span>
→ x ⋅ y = y ⋅ x → <span>That means you can switch ( = commute) factors anyway, the product will remain the same.</span>
