Step-by-step explanation:
We want to evaluate

We use special angles or the unit circle to obtain;

This implies that;



Answer:
(-1,-2)
Step-by-step explanation:
There is a solution where the two expressions intersect. We can plug in what we know in the first equation in the second.
x= -1
y=3x+1
y= 3(-1)+1
y= -3+1
y= -2
Plugging y value in the equation to find x:
-2=3x+1
-3=3x
x= -1
Therefore, the point is (-1,-2)

Answer:
20 Lizard lollies.
Step-by-step explanation:
There are 10 lizard lollis. This is out of 10+4+6 = 20 total treats. This makes the probability of drawing a lizard lollis 10/20 = 1/2.
This means out of 40 treats handed out, we can expect him to give out 1/2(40) = 20 lizard lollis.
The area of a circle is Pi * R^2 (or R * R).
Since we have our radius, R, we can solve.
With our given answer choices, we do not need to multiply R by Pi, instead we will square R, as that's our only option.
4.5 x 4.5 = 20.25.
Our area is now 20.25Pi.
Your answer is C.) 20.25Pi.
