Answer:
1296
Step-by-step explanation:
6x6x6x6
6^4
Answer: The slope is -8/3
Step-by-step explanation: Use the slope formula y2-y1/x2-x1
so -9-7/2-(-4) = -16/6 which can be divided by 2 to get -8/3
One way it's useful is in the application of phasors in physics. Phasors require you to add up vectors of two different angles, so the cosine angle addition formula can be used if you already know the cosine and sine of the original vector angles.
(y + 7)(y + 7)
49 is a perfect square of 7
it can also be written
(y + 7)²
hope this helps :)
