The total angles of a triangle must add up to 180 degrees, so y = 64 degrees
Your answer should be 16/9
Answer:
negative multiples of 3 less than -3
Step-by-step explanation:
if m <9, then
m ={8,7,6,5,4,3,2,1,0,-1,-2,....,..........}
And |6m-55|
So is said that,
when, m= 8
6(8)-55=-6
when, m=7
6(7)-54=-12
when, m = 6
6(6)-54=-18
Since the trend is negative multiples of 3 less than -3
this is my answer
Answer:
Ten is the answer
Step-by-step explanation:
Vertex: (-5,-2); parabola opens up;
General form of the equation for a vertical parabola opening up is:
y-k = a(x-h)^2; knowing that the vertex is at (-5,-2), we can write:
y+2 = a(x+5)^2. We need to find the value of the coefficient a.
From the graph we see that y is 10 when x is approx. -1 3/4 (or -7/4).
subst. these values into y+2 = a(x+5)^2, we get:
10 + 2 = a(-7/4 + 5)^2, or 12 = a(13/4)^2, or 1 = a(169/16).
Solving for a: a = 16/169 = 0.09, or approx 16/160, or 1/10. Unfortunately, this is not close to any of the four answer choices.
I thought it best to try again, and fortunately my second try was correct:
10+2 = a(13/4)^2, or (169/16)a. Thus, 12 = a(169/16)
12
Solving for a: a = ------------- = 1.14. The answer choice closest to this is 1.
169/16
Answer A is correct.
