Answer:
3*5^2
Step-by-step explanation:
75 is divisible by 3
75/3 = 25
25 is not divisible by 3, but it is divisible by 5.
25 = 5^2.
25/25 = 1. We are done.
The total amount of money he had to pay for the bike is $3,954.02 because 6 percent of 7 is 4.2
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
