10 x 523.6 inches = 5236 inches.
5236 inches is equal to 0.08262311 miles.
Answer:
C
Step-by-step explanation:
Any point (x, y) on the parabola is equidistant from the focus and the directrix.
Using the distance formula
= | y - 3 | ← square both sides
(x - 3)² + (y - 1)² = (y - 3)² ← expand the y- factors
(x - 3)² + y² - 2y + 1 = y² - 6y + 9 ← subtract y² - 2y + 1 from both sides
(x - 3)² = - 4y + 8 ( subtract 8 from both sides )
(x - 3)² - 8 = - 4y ( divide both sides by - 4 )
- (x - 3)² + 2 = y, that is
y = - (x - 3)² + 2 → C
Your answer is B. 48 miles. This is because the formula a² + b² = c² can be used to find the hypotenuse, which means the formula
a² - c² = b² can be used to find the side of a right triangle. This means that we can do
50² - 14² = 2304, and then we square root it to get 48.
I hope this helps!
8 hours
1 x 8 = 8
.2 x 10 = .20
.10 = 1
.20 - .10 or 1 = 1
1+1 = 2
2+ 8 = 10 hours
