3 Saturn yrs = 88.2 Earth yrs
Answer:
14.225 kilometers.
Step-by-step explanation:
Monday 3.6
Tuesday 4.705
Wednesday 5.92
By using the addition operation, the total distance, in kilometers, that Andrea ran over the three days will be :
3.6 +4.705 +5.92=14.225
Hence, the total distance that Andrea ran over the three days = 14.225 kilometers.
Answer:
Step-by-step explanation:
The first parabola has vertex (-1, 0) and y-intercept (0, 1).
We plug these values into the given vertex form equation of a parabola:
y - k = a(x - h)^2 becomes
y - 0 = a(x + 1)^2
Next, we subst. the coordinates of the y-intercept (0, 1) into the above, obtaining:
1 = a(0 + 1)^2, and from this we know that a = 1. Thus, the equation of the first parabola is
y = (x + 1)^2
Second parabola: We follow essentially the same approach. Identify the vertex and the two horizontal intercepts. They are:
vertex: (1, 4)
x-intercepts: (-1, 0) and (3, 0)
Subbing these values into y - k = a(x - h)^2, we obtain:
0 - 4 = a(3 - 1)^2, or
-4 = a(2)². This yields a = -1.
Then the desired equation of the parabola is
y - 4 = -(x - 1)^2
