Answer:
Since g(x) = f(2x), this means we substitute 2x in place of x for f(x):
g(x) = f(2x) = (2x)² = 4x²
Graphing this, the parabola is not moved from the parent graph f(x) = x², but the graph is compressed horizontally by a factor of 4.Step-by-step explanation:
Answer:
Both legs would be 20
Step-by-step explanation:
In the image below, it shows the relationship between the legs and the hypotenuse in every 45 45 90 triangle. If we know that the hypotenuse is 20, then the 2 legs are both 20.
I am slightly confused with the problem since they asked for the "short" leg and the "long" leg. Both legs should be the same length because a 45 45 90 triangle is isosceles, with the two legs being the same length.
Answer:
Step-by-step explanation:
It is true that for any given odd integer, square of that integer will also be odd.
i.e if
is and odd integer then
is also odd.
In the given proof the expansion for
is incorrect.
By definition we know,

∴ 
Now, we know
and
will be even values
∴
will be odd
hence
will be odd, which means
will be odd.
