Simplify and evaluate
9) 6x^2 - 27 + 4x^3
10) -7x2 - 5x + 9
Answer:
(For the first two questions I do believe that you will need a protractor to calculate the angles.)
15)
measures out to -70° in order to display that the angle would be in quadrant IV (the bottom right quadrant.)
The first image attached shows where the angle should be located.
16)
is equal to 60° (the line you draw will be in quadrant 1 (the top right quadrant))
17) 350° is
or 6.11 (the answer depends on the format the professor wants.)
18) 240° is
radians or -4.19 (I am rounding to the nearest hundredths place the unsimplified answer is −4.18879020...)

Since we get a negative number in the next column, we must take 1 from the next column and carry it over to this column. Now the number will be changed to 10.
We calculate

, and the result is

Therefore,
All we really need to do here is to convert 2 cm to meters. There are 100 cm in 1 meter, so the appropriate cm to meters conversion factor is
1 meter
-----------
100 cm
Thus,
2 cm 1 m
-------- * ----------- = (1/50) m = 0.02 m or 2.0*10^(-2) m (answer)
1 100 cm
