-2w (w + 8)
Assuming that it is a polynomial from which you must find the roots, we must first rewrite it:
-2w (w + 8) = 0
The roots are then:
w1 = 0
w2 = -8
Assuming you only have to rewrite the expression, the answer is:
-2w ^ 2 -16w
Answer:
w1 = 0
w2 = -8
-2w ^ 2 -16w
There would be 9 birds left. 10-1=9
Answer:
See below
Step-by-step explanation:
The interval must be chosen so that the function is one-to-one, and the sine and cosine functions are not one-to-one on the same intervals.
What are the angles?
if all of them are below 90 degrees, it is acute.
if one angle is 90 degress, it is right
if one angle is more than 90 degrees, it is obtuse
A) 5 to be chosen among a Total : 10 Men + 8 Women
¹⁸C₅ = (18!)/(5!)(13!) = 8,568 groups of five
b) A must to have men and women. If so we have to deduct all groups of 5 that are all men and all group of 5 that are all women
Groups of 5 with only men: ¹⁰C₅ = 252
Groups of 5 with only women: ⁸C₅ = 56
So number of committees of 5 men and women mixed =
8568 - 252 - 56 = 8,260 committees
c) 3 Women and 2 Men:
⁸C₃ x ¹⁰C₂ = 2,520 groups of 3 W and 2 M
d) More women than men, it means:
3 W + 2 M OR (we have found it in c) = 2,520)
4 W + 1 M OR ⁸C₄ x ¹⁰C₁ →→→→ = 700
5 W + 0 M OR ⁸C₅ x ¹⁰C₀ →→→→ = 56
Total where W>M = 3,276 groups of 5 where women are at least 3
