Answer:
a.) 18000 x (0.88)^x
x=number of years
b.) value after 10 yrs is represented by
18000 x (0.88)^10 = about $5013
Step-by-step explanation:
Answer:
0.8
Step-by-step explanation:
We begin with the expression: 
First, we need to convert the fractions into decimals to make this easier.
and 
Once we have this, we can simplify it
Multiply each term by a^2b^2:-
b^2y^2 + a^2x^2 = a^2b^2
subtract a^2x^2 from both sides
b^2y^2 = a^2b^2 - a^2x^2
Now divide both sides by b^2
y^2 = a^2 - a^2x^2 / b^2 = a^2 (1 - x^2/b^2)
take positive square root ( because y > 0)
y = a sqrt(1 - x^2/b^2)
The equation for this would be:
y+6= 1/5(x+7)
