She should use Mean. That is when you add together all of the numbers, then divide by the number of numbers. Her average grade is 80.75, or rounded it is 81.
The answer is -28/3 or 9.33333333333 have a great day also could I get brainliest
Additive inverses combine to get 0. So, k is -1.4. The sum is 0. Hopefully that will help.
Based on the graph given, the option that will show the same amplitude as function m is graph D.
<h3>Which graphed function is this about?</h3>
The cosine function is seen as:
f(x) = A*cos(kx) + M
And the functions are:
- A stands for amplitude,
- k is angular frequency,
- M is the midline.
When the function is m(x) = -2*cos(x+π).
The absolute value of the amplitude will be 2*|-2| = 4
Therefore, the option that can have the requirement above is graph D.
