Answer:
y-intercept: 
axis of symmetry: 
vertex: 
Step-by-step explanation:
To find the y-intercept, set x = 0 and solve for y.
I am assuming f(x) = y
The y-intercept of the equation is y = 0.
Now, for the axis of symmetry, you need the equation 
In an equation.. 
In this case, there is only an a, so plug in the values into the equation.
The axis of symmetry is x = 0.
To find the vertex, change the format of the equation from standard form to vertex form.
Vertex form: 
The vertex is 
The vertex in this case is (0,0).

Answer:
5878600 different playlists.
Step-by-step explanation:
Since we require 14 songs for the playlist and there are 7 hip-hop, 5 jazz, 7 pop, and 8 blues songs, and DJ Mykel wants to play no more than 3 hip-hop songs, the number of ways in which he can combine the 7 hip-hop songs to play no more than 3 is ⁷C₃ = 7!/4!3!.
Now, since we have 3 songs already selected, we are left with 14 - 3 = 11 songs to select.
Since we have selected the 3 hip-hop songs, we are left with 5 jazz, 7 pop, and 8 blues songs which sum to a total of 20 songs.
So, we have 20 songs to select in 11 ways which is ²⁰C₁₁ = 20!/(20 - 11)!11! = 20!/9!11!
So, the number of different playlists that can be formed is thus
⁷C₃ × ²⁰C₁₁ = 7!/4!3!.× 20!/9!11!
= 35 × 167960
= 5878600 different playlists.

Answer:
12
Step-by-step explanation:
(whole secant) x (external part) = (whole secant) x (external part)
( 7+x+2) * 7 = ( 6+8) * 6
Combine like terms
(9+x) *7 = 14*6
Distribute
63 +7x = 84
Subtract 63
63 +7x -63 = 84-63
7x =21
Divide by 7
7x/7 = 21/7
x = 3
KM = x+2+7
= 3+2+7
=12
