If the discriminant b² - 4ac < 0
There are no real solutions
Answer:
x= 16 ft.
Step-by-step explanation:
Let 'x' and 'y' are the lengths of the two pieces then:
1.) x + y = 36
2.) x : y = 4 : 5 cross multiply
3.) 5x = 4y
by solving the system of equations
x + y = 36
5x = 4y
we find
x = 16 ft
y = 20 ft
The lowest term is
.
Solution:
Given expression is 
<u>To reduce this term to the lowest term:</u>

Multiply the numerator and denominator.

Now, divide the numerator and denominator by the greatest common factor.
Here 150 and 8 both have common factor 2.
So, divide numerator and denominator by 2.



Hence the lowest term is
.
This is exponential decay which can be expressed as:
y=ab^t, y=final value, a=initial value, b=rate, t=time
In this case a=25000, r=(100-20)/100=0.8 so
y=25000(0.8^t), so in 4.5 years...
y=25000(0.8^4.5)
y≈$9158.93 (to nearest cent)
