Answer:
the first one is -(25/2) OR -12.5
THE Second one is -(125/8) or -15.625
Isocoleese means that 2 sides and hence 2 angles are same measure
acute means that all 3 angles are less than 90 degrees
We can rule out choice I since acut means less than 90
II is a possibility, but it doesn't best describe it
III. that is true, but it doesn't include the isocileese part
IV. that is true, but doesn't include the acute part
not sure, either III or IV
Answer:
A
Step-by-step explanation:
We are given the function:

And we want to find:

Substitute:

And evaluate:

In conclusion, our answer is A.
Answer:
π
Step-by-step explanation:
The *period* of a function is the length it takes before it repeats. Usually, the period of the sine function is 2π; it takes a full rotation around the unit circle for it to repeat. When we replace the input x with -2x, this does a few things:
- Changes the rotation direction
- Makes the rotation go twice as fast
If we rotate around the unit circle twice as fast, it’ll take us half of 2π, or just π to complete a cycle.
Answer:
Aiko should not have put both of the 'i' out of the brackets.
Step-by-step explanation:
As only one integer has i with it, it is not possible to take the i out of the bracket.
