The vertex form of equation of a parabola:
(h, k) - vertex
We have the vertex (-0.5, 2.3). Therefore h = -0.5 and k = 2.3.
Substitute:
We have the point (5, 2.75). Put the coordinstes of the point to the equation of parabola:

Step-by-step explanation:
-1.5(4-n) + 2.8 - 1.5(4-n) + 2.8
Two ways of solving this, you can just expand and solve, or combine like terms then solve. I will combine like terms.
<span>-1.5(4-n) + 2.8 - 1.5(4-n) + 2.8
</span>(2*-1.5)(4-n) + (2*2.8)
-3(4-n) + 5.6
-3*4 + 3n + 5.6
-12 + 3n + 5.6
3n - 6.4
Answer:
$9.3 million
Step-by-step explanation:
Given that the company profit increases by 9% yearly from 2005.
Using the exponential growth formula;
A = P(1+r)^(t) .....1
Where;
A = final amount/value of profit
P = initial amount/value = $6.6 million
r = growth rate yearly = 9% = 0.09
t = time of growth in years = 2009 - 2005 = 4 years
Substituting the values;
A = 6.6(1+0.09)^(4)
A = 6.6(1.09)^(4)
A = 9.3164386 million
A = $9.3 million
The companies profit in the year 2009 to the nearest 10th of $1 million is $9.3 million
