Answer:
- (ax + by + cz)/(a + b + c)
Step-by-step explanation:
<u>In terms of the scores we calculate the sum as:</u>
<u>The number is the sum of the frequencies:</u>
<u>Mean average score is:</u>
- (ax + by + cz)/(a + b + c)
Odd functions are those that satisfy the condition
f(-x)=-f(x)
For example, check if x^3 is odd =>
f(x)=x^3
f(-x) = (-x)^3
-f(x)=-x^3
Since (-x)^3=-x^3, we see that f(x)=x^3 is an odd function.
In fact, polynomials which contain odd-powered terms only are odd. (constant is even)
As an exercise, you can verify that sin(x) is odd, cos(x) is even.
On graphs, odd functions are those that resemble a 180 degree rotation.
Check with graphs of above examples.
So we identify the first graph (f(x)=-x^3) is odd (we can identify a 180 degree rotation)
Odd functions have a property that the sum of individually odd functions is
also odd. For example, x+x^3-6x^5 is odd, so is x+sin(x).
For the next graph, f(x)=|x+2| is not odd (nor even) because if we rotate one part of the graph, it does not coincide with another part of the graph, so it is not odd.
For the last graph, f(x)=3cos(x), it is not odd, again because if we rotate about the origin by 180 degrees, we get a different graph. However, it is an even function because it is symmetrical about the y-axis.
Answer:
when you have a right angled triangle. that is when the angle is 90 degree.
Step-by-step explanation:
you will use pythagorean theorem when you have a right angled triangle. that is when the angle is 90 degree.
that is when you will have he opposite side , hypotenuse side and adjacent side.
2/16, 3/24, 4/32 is that what your asking?
