Answer:
Solution : ( - 8, - 5π/3 )
Step-by-step explanation:
There are four cases to consider here, the first two with respect to r > 0, the second two with respect to r < 0. For r < 0 we have the coordinates ( - 8, 60° ) and ( - 8, - 300° )
. - 300° in radians is - 5π/3, and hence our solution is option d. But let me expand on how to receive the coordinates. Again r is the directed distance from the pole, and theta is the directed angle from the positive x - axis.

So when r is either negative or positive, we can tell that this point is 8 units from the pole. Therefore - r = - 8 in both our second cases ( we are skipping the first two cases for simplicity ). For r < 0 the point will lay on the ray pointing in the opposite direction of the terminal side of theta.
Our first coordinate is ( - 8, 60° ). Theta will be 2 / 3rd of 90 degrees, or 60 degrees, for - r. Respectively the remaining degrees will be negative, 360 - 60 = 300, - 300. Our second point for - r will thus be ( - 8, - 300° )
. - 300° = - 5π/3 radians, and our coordinate will be ( - 8, - 5π/3 ).
Hi,
To solve this expression, use the inputs of the x and y values to calculate the expression and result with an output.
x=5
y=8
Plug in values:
5 (5 + 2) + 5^(2) + 8
Evaluate:
5 (5 + 2) + 5^(2) + 8 = 5 ( 7 ) + 5^(2) + 8
5 (7) + 25 + 8
35 + 25 + 8
=68
Your final answer is 68.

Answer:
x > -1
Step-by-step explanation:
To solve the inequality, use the same rules as solving equations.
2 - 2x < 4
-2x < 2
x > -1
Since you divide by a negative, you must switch the sign < to >.
Answer:
Step-by-step explanation:
curtis is 22 min 16 sec carol is 18 min 6 sec
4 mins and 10 seconds it the difference
Well you can take out a 7 and y^2 since both have it.
-3y should be your answer because you got rid of 7y^2 and then you have to divide -21/7 to get -3. Also if you take y^2 from y^3 you are left with just a "y".
