1 apple would cost $.25.
2 apples would cost $.50.
3 apples would cost $.75
4 apples would cost $1.00
6 apples costs $1.50
7 apples costs $1.75
Use this equation y = a (1 - b)^x
Where a is the initial population and b is the decay factor: 40/100 = 0.4
Therefore, the answer is that the decay factor b is 0.4.
This table shows some figures using the decay factor.
year decrease population
0 0 a(1 - 0.4)^0 = a
1 a*0.4 a (1 - 0.4)^1 = a*0.6 = 0.6a
2 0.6a*0.4 a(1 - 0.4)^2 = a(0.6)^2 = 0.36a
3 0.36a*0.4 a(1 -0.4)^3= a(0.6)^3 = 0.216a
The ordered pair that is the solution to these equations is (-2,-1)
work:
2(-2)+5(-1)=-9
3(-2)-4(-1)=-2
Answer:
X=45
Step-by-step explanation:
Lines AC and CD meet at a right angle so you half 90 =45
