Step-by-step explanation:
The number of people in Pinellas country has been changing at a rate of 1.3% per year.
If in the year 2016, there were 960,730 people in the country and if x represents the number of years since 2016, then the function that models the number of people in the country after x years since 2016 is
⇒

Answer:
Since b^2 -4ac = 256 we have 2 real distinct root roots
Step-by-step explanation:
4x^2+12x=7
We need to subtract 7 to get it in the proper form
4x^2+12x-7=7-7
4x^2+12x-7=0
The discriminant is b^2 -4ac
when the equation is ax^2 +bx+c
so a =4 b=12 and c=-7
(12)^2 - 4(4)(-7)
144 +112
256
If b^2 -4ac > 0 we have 2 real distinct roots
If b^2 -4ac = 0 we have one real root
If b^2 -4ac < 0 we have two complex root
Since b^2 -4ac = 256 we have 2 real distinct root roots
Answer:
5 1/6
Step-by-step explanation:
Note that - ( -7 1/3) = 7 1/3. The two ' - ' signs cancel each other.
Thus, the original expression becomes -2 1/6 + 7 1/3.
Here the LCD is 6. We re-write the above expression as -2 1/6 + 7 2/6.
Reversing the order of these terms makes the work a bit easier.
7 2/6 - 2 1/6 comes out to 5 1/6
