4.
This is because 4 goes into 16 4 times, hence 4 x 4 being 16.
Therefore, the answer would be four.
Hope this helps!

<em><u>Solution:</u></em>
Given that,
We have to find whether the above function is odd or even
If a function is: y = f(x)
If f(-x) = f(x), the function is even
If f(-x) = - f(x), the function is odd
Which is,
From given,
Replace x with -x
Therefore,
Thus the function g(x) is even

"When the storm began", it means it has been snowed for 0 hours, so n=0.
f(0)=2.5, thus the <span>depth of snow was 2.5 inches when the storm began.
f(n+1)=f(n)+0.8, so f(n+1)-f(n)=0.8
it means when the time increases by one hour, the depth of snow increases by 0.8 inches.</span>
The area of the actual square window = 2.25 m².
<h3>Scale Drawing</h3>
Scale drawing relates the actual length of an object to its length on a paper.
Given a scale of 1 in = 2 m, it means 1 in on paper is about 2 m of the actual length of the object.
Thus:
- Length on scale drawing = 0.75 in
- Actual length = x
Therefore:
1/2 = 0.75/x
x = 1.5 m
Area of the actual square window = 1.5² = 2.25 m².
