This is a parabola which has vertex at the origin and opens upwards.
general form is x^2 = 4ay where a is the focus
the focus is the same distance from the vertex as the directrix So it is at the point (0, 6)
required equation is x^2 = 4*6 y
or y = (1/24) x^2
Answer:
x=14/6
Step-by-step explanation:
Answer:
4.5 miles
Step-by-step explanation:
so basically 1 hour equals 60 minutes so we divide 60 by 20 because he can ride 1.5 miles in 20 minutes. so 60/20 is 3 and now all we do is multiply 1.5 by 3 which gives us 4.5.
Answer: 1,225 ≤ 2t - 500
Step-by-step explanation: t = tickets
Answer:
0, -10, -20, -30, -40, -50, ..., -10(n-1)
Step-by-step explanation:
An arithmetic sequence with a common difference of -10 just indicates that each term adds negative ten to the prior one, which is just subtracting ten. If you slap a random value as the beginning, zero in my example, then you spam subtract negative tens, you get an arithmetic sequence. The variable "n" is just the term number - 0 was n=1, -10 was n=2, -20 was n=3, etc.
