Answer:
3π in^2
Step-by-step explanation:
Area of the circle before folding = π r^2
= 6^2 π
= 36 π is^2
The area of the resulting shape = 1/2 * 1/2 * 12π
= 3 π in^2.
We have a property for odd functions, which is given below. Let f(x) be an odd function then it must satisfy the below - mentioned property.

Now, we have been given the function 
For this function to be odd, it must satisfy the above written property.
Replace x with -x, we get

And, we have to also find

Hence, in order to the given function to be an odd function, we must determine whether 9-4(-x)^2 is equivalent to -(9-4x^2) or not.
Therefore, C is the correct option.
Start with second, third and fourth degree of imaginary unit i:

.
Since 233=232+1=4·58+1, then

.
Answer:
Answer:
23.6 (approximate value)
Step-by-step explanation:
- a*a+b*b=c*c Pythagorean thereom
- (21.5)^2 + b*b = (31.9)^2
- b*b= 1017.61 - 462.25
- √b*b= √555.36
- b=23.6(approximate value)
