Answer:
see explanation
Step-by-step explanation:
the equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Given the equation in standard form : ax² + bx + c : a ≠ 0
then the x-coordinate of the vertex is
= - 
j(x) = x² - 12x + 7 is in standard form
with a = 1, b = - 12 and c = 7, hence
= - 
= 6
substitute x = 6 into j(x) for y- coordinate
y = 6² - 12(6) + 7 = 36 - 72 + 7 = - 29
vertex = (6, - 29 ) and
j(x) = (x - 6)² - 29 ← equation in vertex form
Answer:
7/20 is not equivalent to 1/3
Answer:
yes
Step-by-step explanation:
Substitute the points into the equation
y =x
3=3
This is true so (3,3) is a solution
Answer:
Step-by-step explanation:
We have to simplify this equation.
<u>Like this:</u>
<u>The closest number to x is 19:</u>
<u>Solve:</u>
- 2 * 19 + 8 = 46
- = 38 + 8 = 46
- = 46.
x = 19.
Given
Quadratic model
Find
number of salespeople maximizes the company's profits
Explanation
as we see from the curve that maximum monthly profit is between 35 to 40 ,
so , it is approximately near to 37 sales people.
Final Answer
Hence , the best option is B
