Answer:
Step-by-step explanation:
Given that there is a function of x,
Let us find first and second derivative for f(x)
When f'(x) =0 we have tanx = 1 and hence
a) f'(x) >0 for I and III quadrant
Hence increasing in 
and decreasing in 
Hence f has a maxima at x = pi/4 and minima at x = 3pi/4
b) Maximum value = 
Minimum value = 
c)
f"(x) =0 gives tanx =-1
are points of inflection.
concave up in (3pi/4,7pi/4)
and concave down in (0,3pi/4)U(7pi/4,2pi)
Answer:
2 is scalene
3 is right
4 is right
5 is equalatirel
6 is scalene
7 is isocoles
8 is equalatirel
9 is right
Step-by-step explanation:
Well the square root of 72 is 8.485 and the square root of 45 is 6.708. hope this helps :)
100% because
is 6 and
is 9 meaning that the sum will come up at 6 or 9 also meaning that its 100%
Answer:
Infinate
Step-by-step explanation:
If you multiply all factors in the secon eqation by 5, you will get the first eqation.
Therefore for any value of x you can find y, thus having an infinate number of x,y pairs
