Answer:
see the formula in book
Step-by-step explanation:
change the first 2 brackets into cos sin like that
then after,change both into another formula
sin theta plus cos theta will come ans
Answer:
k = - 2
Step-by-step explanation:
Given α and β are the zeros of x² - 6x + k = 0 , with
a = 1, b = - 6 and c = k , then
α + β = - 
= - 
= 6
αβ = 
= 
= k
Then solving
(α + β)² - 2αβ = 40
6² - 2k = 40
36 - 2k = 40 ( subtract 36 from both sides )
- 2k = 4 ( divide both sides by - 2 )
k = - 2
G = how many contests that Gertrude won
e = how many contests Elena won
Gertrude 4 more times than Elena
g = e + 4
They won a total of 18 contests
g + e = 18
.. Please... Please tell me you know fractions at least well enough to know this ;_;
3/4 is like 0.75, yeh?
3/8 is like.. 0.365
Change the Denominator (Bottom Number in Fraction) so they're the same:
6/8 3/8.
Now d'you see?
