Answer:

Step-by-step explanation:

100 is divided by 4, so you will get 25.
25 multiply 3, you will get 75%
So, the answer is 75%.
The inequality that describes the possible values of the expression is:

<h3>What is the lower bound of values of the expression?</h3>
The expression is given by:

To find the lower bound, we try to see when the expression is negative, hence:


Applying cross multiplication and simplifying the 3's, we have that:

From the bounds given, this expression will never be true, at most they can be equal, when:
a = b = 4.
Hence the lower bound of values of the expression is of 0.
<h3>What is the upper bound of values of the expression?</h3>
The expression is a subtraction, hence we want to maximize the first term and minimize the second.
Considering that the first term is direct proportional to b and inverse to a, and the second vice versa, we want to:
Then:

Hence the bounds are:

Answer:
tan(45°) = 1
Step-by-step explanation:
We know that sin (45°) = √2/2, and cos(45°) = √2/2.
Given that tan(x) = sen(x) / cos(x), we get:
tan(45°) = (√2/2) / (√2/2) = 1
Therefore, tan(45°) = 1
