Answer:

Step-by-step explanation:
The polynomial
can be factored exactly the same as the polynomial
. Here it factors into two numbers which multiply to 16 but add to 8. These factors are 8 and 2. So it factors into the expression (x+8)(x+2).
For the polynomial
it factors into the same factors except x ^n is used instead. The factors are 
Just multiple and you will get the percent you need for the answer
Answer:
The function rule in slope-intercept form is:

Step-by-step explanation:
The slope-intercept form of a function is given as:

Here
m is the rate of change of function and b is the y-intercept
The rate of change is calculated as:

For this, any two pairs of input and output can be taken.
So using the pairs (1,-3) and (2,-1)

Putting the value of slope in slope-intercept form

Putting (1,-3) in the equation

Putting the value of b

Hence,
The function rule in slope-intercept form is:

We use the formula for exponential growth:
P = Po exp(kt)
Using the population data from 1993 to 1996, we can solve for the growth rate k
76 = 72 exp(k(3))
76/72 = exp(3k)
ln (76/72) = 3k
k = ln(76/72) / 3 = 0.0180
In 10 years (2003), the population will be:
P = Po exp(0.0180t)
P = 72 exp(0.0180(10))
P = 86.22 million
B over 2 when u complete the square the only thing you do is find a,b,c when you find b you have to divide it by 2 then square root it.
