Answer:
Step-by-step explanation
The given point 
tells us that the terminal side of 
is in the fourth quadrant.
From the diagram in the attachment,
We can use the Pythagoras Theorem to find the length of the hypotenuse of the right triangle.
Let the hypotenuse be 
. Then,
Now we use the sine ratio;
.
But since the terminal side of is in the fourth quadrant, the sine ratio must be negative.
This implies that;
.
We rationalize the denominator to get;
.
The answer would be 3, 2-2+3, I’m pretty sure.
Here is the solution of the given problem above:
Let s= staples
<span>c = chalk</span>
<span>c + 2s = 10 </span>
<span>3c + 2s = 18 </span>
<span>-c-2s = -10 </span>
<span>3c + 2s = 18 </span>
<span>2c = 8 </span>
<span>c = 4 </span>
<span>s = 3
</span>Therefore, the price per chalk box is $4 and per stapler is $3.
So the total cost of the chalk and stapler would be $7.

Answer:
Step-by-step explanation:
Parts of the question are missing.
y = a(x-h)² + k is a vertical parabola.
If a is positive, the parabola opens upwards.
If a is negative, the parabola opens downwards.
The vertex is at (h, k)
