Answers:
Vertex is (-1,0)
Axis of symmetry is x = -1
============================================
Explanation:
F(x) = 3(x+1)^2
is the same as
y = 3(x-(-1))^2 + 0
which is in the form
y = a(x-h)^2 + k
We can see that
a = 3
h = -1
k = 0
Therefore the vertex is (h,k) = (-1,0)
The axis of symmetry is x = h = -1 which is the equation x = -1
The axis of symmetry in this case is a vertical line through the vertex.
Answer:
1/12
Step-by-step explanation:
subtract the four soloists who can't be chosen from the total musicians
16-4=12
Itzhak is one person out of 12 who could be chosen to speak
Also the question is annoying because nobody calls an orchestra with 16 people a "16 piece orchestra"
There are 360 degrees. So add the 2 angles you have: 95+45=140. Subtract that from the number of degrees: 360-140=220. X=220 :)
