Original Income = 15,000
New income = 20,000
The percentage Increase in the income can be calculated as:
%
The change in income = 20000 - 15000 = 5000
Using the values, we get:
%
=
%
This means, Pats income increased by 33.33% in a period of ten years
Answer:
The area of the bases must be the same.
Step-by-step explanation:
Volume=LxWxH
Length and width create the base so another formula would be V=B•h, and if they have the same height they would need the same base. Hope this helps, sorry if I’m incorrect.
Answer:
is an even function.
Step-by-step explanation:
Recall when it means when a function is even or odd. An even function has the following property:
And an odd function has the following property:
So, let's test some values for cos(x).
Let's use π/3:
From the unit circle, was can see that this is 1/2 (refer to the x-coordinate).
Now, let's find -π/3. This is the same as 5π/3. Thus:
And again from the unit circle, we can see that this is 1/2.
Therefore, despite the negative, the function outputs the same value.
Cosine is an even function.
Notes:
Cosine is an even function and sine is an odd function. It's helpful to remember these as they can help you solve some trig problems!
