Answer:
answer is also 60.
Step-by-step explanation:
Since angle 2 is also 60 degrees, angle 6 will also be 60 degrees.
Answer:
See below
Step-by-step explanation:
then f(x)=0 if x<0 and f(x)=x if x≥0.
When x→-∞, f is the constant function zero, therefore
. When x→∞, f(x)=x and x grows indefinitely. Thus 
f is differentiable if x≠0. If x>0, f'(x)=1 (the derivative of f(x)=x) and if x<0, f'(0)=0 (the derivative of the constant zero). In x=0, the right-hand derivative is 1, but the left-hand derivative is 0, hence f'(0) does not exist,
f'(x)>0 for all x>0. Therefore f(x) is strictly increasing on the inverval (0,∞).
Answer: -26 27/40
Step-by-step explanation:
1. 5/8 + 1/8 = 6/8 --> 3/4
3. - 1/4+ 3/4:
-0.25+0.75= 0.5 OR 1/2
5. 5/9 + 5/9 = 10/9 --> 1 whole 1/9
7. 3/10 + 1/10 = 4/10 --> 2/5
9. 7/15 + 4/15 = 11/15
And I simplified them too :P
Also this is ez, to me :PP
