6-4x=-2x +4
6=2x +4
2=2x
So
X=1
The total number of fans modeled by the function:
f(x) = 50x3+1549x2-2186x+8120
The number of professional football games are modeled by the function:
g(x) = 25x+812
x is the number of years since 2005
The total number of fans modeled by the function:
f(x) = 50x3+1549x2-2186x+8120
The number of professional football games are modeled by the function:
g(x) = 25x+812
x is the number of years since 2005
Division by Long division method:
50x^3+1549x^-2186x+8120 divide by (25x+812)
=2x^2-3x+10
Hence the expression for the average number of fans per football game is given by:
h(x) = 2x2-3x+10
Answer:
Option C
Step-by-step explanation:
- Initial balance= $11
- Interest rate = 1.9% PA simple
<u>It will be graphed as function:</u>
Since is has a very small slope of 0.019 it will be shown almost parallel to x axis.
<u>Some points on the graph:</u>
- Amount in 1 year= 11*(1+0.019) = $11.21
- Amount in 2 years = 11*(1+2*0.019) = $11.42
- Amount in 6 years = 11*(1+6*0.019) = $12.25
- Amount in 10 years = 11*(1 + 10*0.019) = $13.09
Correct graph is option C
Let the original price be x
selling price = $34
discount = 15%
Therefore S.P. = 100-15/100 * x
So, x = 34 * 100/85
= 3400/85
= $40
