Answer:
   (d)  f(x) = -x²
Step-by-step explanation:
For the vertex of the quadratic function to be at the origin, both the x-term and the constant must be zero. That is, the function must be of the form ...
   f(x) = a(x -h)² +k . . . . . . . . . . vertex form; vertex at (h, k)
   f(x) = a(x -0)² +0 = ax² . . . . . vertex at the origin, (h, k) = (0, 0)
Of the offered answer choices, the only one with a vertex at the origin is ...
   f(x) = -x² . . . . . a=-1
 
        
             
        
        
        
Answer:
Felicia's gross monthly income = $4,583.33 (Approx.)
Step-by-step explanation:
Given:
Annual income = $55,000
Find:
Felicia's gross monthly income
Computation:
Gross income per month = Annual salary / Number of month in year
Gross income per month = Annual salary / 12
Felicia's gross monthly income = Annual salary / 12
Felicia's gross monthly income = 55,000 / 12
Felicia's gross monthly income = $4,583.33 (Approx.)

Answer:
35:
30 (tens) 5 (ones)
16:
10 (tens) 6 (ones)
Step-by-step explanation:
Add the tens:
30+10 =40
Add the ones:
5+6=11
Add the final answer for the tens and ones together:
40+11=51

Answer:
1)	n^2 – 3 n + 8   4^2 – 3*4 + 8 = 12    
2)    (x^2 – 4 y) / 2      (16 + 12) / 2 = 14
3)	4 * |-7 – 2| = 4 * 9 = 36     Abs -9 = 9  
4)	19 – x^2 = 19 – 25 = -6     (-5)^2 = 25
5)	S^2 t – 10 = -8^2 * ¾ -10 = 64 * ¾ - 10 = 38
6)	4 p^2 + 7 q^3 = 4 * 9 + 7 * (-8) =  - 20      (-2)^3 = -8
