Answer:
½√2
Step-by-step explanation:
∑ₙ₌₀°° (-1)ⁿ π²ⁿ / (4²ⁿ (2n)!)
∑ₙ₌₀°° (-1)ⁿ (π/4)²ⁿ / (2n)!
Using the Taylor expansion for cos x:
cos (π/4)
½√2
|RZ|=0.5|SW| therefore 2|RZ|=|SW|.
5x - 20 = 2 · 30
5x - 20 = 60 |add 20 to both sides
5x = 80 |divide both sides by 5
x = 16
Answer:
The brainliest!
Step-by-step explanation:
c= 7/6k- 17(7/6)
6/7c = k - 17
k = 6/7c+17
Answer:
5y+6=3y+9
We move all terms to the left:
5y+6-(3y+9)=0
We get rid of parentheses
5y-3y-9+6=0
We add all the numbers together, and all the variables
2y-3=0
We move all terms containing y to the left, all other terms to the right
2y=3
y=3/2
y=1+1/2
