Answer:
<em>Axis of symmetry line is parallel to y- axis</em>
Equation of the parabola <em> ( x - ( -2 ))² = (y - 12 ) </em>
Step-by-step explanation:
<u><em>Explanation</em></u>:-
Given equation is y = x²+4 x+16
y = x²+2 (2 ) x + (2)² - (2)² + 16
y = ( x + 2 )² + 12
( x + 2 )² = y - 12
<em> ( x - ( -2 ))² = (y - 12 ) </em>
( x- h)² = 4 a ( y - k)
<em> Center (h ,k) = ( -2 , 12)</em>
<em> Here 4 a = 1 </em>
<em> a = 1/4</em>
<em>Focus S = ( h , K +a) = ( -2 , 12 + 0.25) = ( -2 , 12.25)</em>
<em>Axis of symmetry line is parallel to y- axis</em>
Answer:

Step-by-step explanation:
Given that,
The sum of first n term of a sequence is
We need to find the sum of the first 5 terms.
Put n = 5,

So, the sum of first 5 terms is equal to
.
Answer: 500
Step-by-step explanation:
The remainder of the question is:
How many units does the company need to sell to reach the target profit?
The required sales to break even will be calculated as:
= (Fixed cost + Required profit) / ( Price per unit - Variable cost)
= (120000 - 80000) / (100 - 20)
= 40000/80
= 500
The company needs to sell 500 units.
