B 0<x<12
Step-by-step explanation:
anything bigger won't be able to reach
Answer:
perpendicular lines
Step-by-step explanation:
because they intersect, they do not go even next to each other forever.
Answer:
32.6
Step-by-step explanation:
opp/adj = 3.2/5
I= tan -1(3.2/5)
I =32.6192
=32.6
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
I'm 100% sure the answer is d. II and IV
because $257.72 - $248.53 = $9.19
and $73.98 - $64.79 - 9.19
i hope this helps :)
