To solve this problem yu must apply the proccedure shown below:
1. You have that the <span>focus of the parabola is located at (0,–2) and the directrix is represented by y=2. Therefore, you have:
</span>
√(x0-0)²+(y0-(-2))²=|y-2|
2. By simplifying and clearing x², you obtain:
(√x0²+(y0+2)²)²=(y0-2)²
x0²+(y0+2)²=(y0-2)²
{ Note: x0²=x and y0=y)
x²=-8y
The answer is: x²=-8y
Of course! Just study hard, exams are a big part of your grade most of the time! I also have exams
Answer:
18.84 feet. let me know if you have ay other questions.
Step-by-step explanation:
The way to find the formula for circumference is kinda complicated so it is best to ust memorize the formula, which is 2πr. or 2 times pi times the radius.
Your problem gives you the formula, but instead of 2 and r in it you have d, which is the diameter.
The diameter of the circle is 2 times the radius, so that's why it is replaced.
the radius is the distance from the center fo the circle to one edge, and the diameter is the distance through the circle passing through its center. so it's the center to one end plus the center to another end. or r+r which is also 2r.
So d = 2r, so in this problem d =6 feet.
So now the formula πd = 3.14*6 feet = 18.84 feet
