Answer:
The third option listed:
Step-by-step explanation:
We start by writing all the numerical factors inside the qubic roots in factor form (and if possible with exponent 3 so as to easily identify what can be extracted from the root):
And now we combine all like terms (notice that the only two terms we can combine are the first two, which contain the exact same radical form:
Therefore this is the simplified radical expression:
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
What are the coefficients in the polynomial 4x²+3x-3?
<u>Coefficient:-</u> A number before a variable
<u>Coefficients in this polynomial:-</u>
4 (the number before x²) and 3 (the number before x)
<h3 />So we conclude that the right option is:-
4, 3 (Option B)
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Answer:
Step-by-step explanation:
In each case, draw the right triangle which produces the inverse trig value. That is, label the two sides as needed, and calculate the third side.
It should be clear that
sin(2α) = 2 sinα cosα
So,
See what you can do with the others.
