Answer:
10 degrees
Step-by-step explanation:
(5x(10))+3=53 degrees
(3x(10))+7=37 degrees
53+37=90 degrees
Since it is under 985,000, you would round it down. So your answer rounded to the nearest ten thousand would be 980,000
Answer:
Step-by-step explanation:
The directrix is a vertical line, so the parabola is horizontal. The focus lies to the left of the directrix, so the parabola opens to the left.
For a left-opening parabola:
x = a(y-k)²+h,
a < 0,
vertex (h,k)
focal length p = 1/|4a|
focus (h-p, k)
directrix: x=h+p
Apply your data
focus (1,-4)
directrix x=2
vertex (1.5,-4).
focal length p = 0.5
a = -1/|4p| = -½
x = -½(y-2)²+ ½
15 cm, as 1 and 3 are too small, 75 is too big, and 15 is just average
100 is 480% , times by 48
