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:
So $28
Step-by-step explanation:
14+12+13+25+32+30=126

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
I hope this helps! Lemme know in the comments if this made sense to you?
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
