Answer:
Converting the equation 
into completing the square method we get: 
Step-by-step explanation:
we are given quadratic equation:
And we need to convert it into completing the square method.
Completing the square method is of form: 
Looking at the given equation
We have a = x
then we have middle term 20x that can be written in form of 2ab So, we have a=x and b=? Multiplying 10 with 2 we get 20 so, we can say that b = 20
So, 20x in form of 2ab can be written as: 2(x)(10)
So, we need to add and subtract (10)^2 on both sides
So, converting the equation into completing the square method we get:
Answer:
a = 30
b = 6/7
Step-by-step explanation:
The number of yeast cells after t hours is modeled by the following equation:
In which a is the initial number of cells.
At time t = 0 the population is 30 cells
This means that 
So
And increasing at a rate of 18 cells/hour.
This means that f'(0) = 18.
We use this to find b.
So
Then, it's derivative is:
We have that:
f'(0) = 18
So
Then
multiply 6.5 times 15.5 times 3.2 which will give you 322.4 so your area is 322.4 cm
A. -3/2
To figure out this problem, you have to use the slope formula.
y2-y1=x2-x1
(-6,8) (2,-4)
-4-8/2+6
-12/8
-3/2
Let n represent the # of students in the class.
Then 8n candies + 4 candies = 5n candies + 40 candies
Combining like terms: 3n = 36 candies. Solving for n, n = 12 students.
