Answer:

Step-by-step explanation:
You need to remember the following equation:

Where a and b is the lengths of the two sides and c is the hypotenuse.
So simply plug these values into this:

36 + 49 = h^2
36 + 49 = 85
So the hypotenuse is the square root of 85:

Answer:
3
Step-by-step explanation:
Period of a function is the period after which the function attains the same value
in the graph attached with this problem we can see that
f(0)=1
the value of x for which function f(x) attains the value 1 again is at
x=3
f(3)=1
similarly , we see
f(6)=1 , f(9)=1
Hence we see that after every increased value of x by 3 units , we attain the same value of function . hence the period of the function is 3
