A line of symmetry is when you can put a line through a shape and you can fold it and it is identical on both sides, and rotational is when you can rotate it and at some point it is in the same spot as it was before, so yes, you are right. the octogon.
Answer:
hello :
Step-by-step explanation:
f(x)=|x²-x-2|
f(x) = x²-x-2 if : x²-x-2 ≥ 0
f(x) = - (x²-x-2) if : x²-x-2 ≤ 0
x²-x-2 = ( x+1)(x-2)
sign of : x²-x-2 is :
x²-x-2 ≥ 0 : x≤ -1 or x ≥ 2
x²-x-2 ≤ 0 : -1 ≤ x ≤ 2
Answer:
Larger number = 32
Step-by-step explanation:
Smaller number = x
Larger number = y
y - x = 8 -----------(I)
3y = 4x ---------------(II)
3y/4 = x
Plug in x = 3y/4 in equation (I)

y = 8*4
y = 32
Plug in y = 32 in equation (II)
3y = 4x
3*32 = 4x
4x = 3*32
x = 
x = 3 *8
x = 24
Answer:
Ans = 7/8
Step-by-step explanation:
28 out of 32
= 28/32
Dividing through by 4
= 28/4 / 32/4
= 7/8
Answer:
(a) even function
(b) odd function
Step-by-step explanation:
From the given information;
Any function x(t) can be said to be the sum of even and odd functions.
i.e.

where;
x(t) is a real function.
For a real and even function, the Fourier transform is also real and even.

Also, the Fourier Transform of a real and odd function is imaginary and odd.

The behavior of X(f) largely depends on the behavior of x(t).
If x(t) is real and even, then x(f) is real and even valued function
Thus, the real part of X(f) is an even function.
If x(t) is real and odd, then x(f) is imaginary and odd valued function
Thus, the imaginary part of X(f) is an odd function.
