Answer:
2x-1 =0 F(x)=(x+1)(x-2)(2x-1)^2
Step-by-step explanation:
Answer:
Step-by-step explanation:
Lets illustrate one method by an example:
Find the square root of 12:
The 2 perfect squares around 12 are 3^2 and 4^2 so the square root of 12 is going to be between 3 and 4.
We might predict it to be 3.5
If we square 3.5 we get 12.25 so we are pretty close.
It is less than 3.5 so we might try 3.4 .
Working 3.4^2 out we get 11.56 so we know the square root is between 3.4 and 3.5 Since 12.25 is closer to 12 than 11.56, the square root is closer to 3.5 than 3.4 so we might try 3.46.
This is called the method of trial and improvement and requires you to do long multiplications.
Answer:
9 at minimum
Step-by-step explanation:
a minimum of 9 because it takes a total of 8 rides to take back a full 18 cars back and the 9th ride takes back the remainder which is 0.27777777778 times 18 cars
Answer:
The quotient of: 
is: 
Step-by-step explanation:
We need to find quotient of:
We know that 
Now solving:
Writing it in scientific notation
So, the quotient of: is:
3 goes in to 40 13 times
7 goes in to 40 5 times
but it is not 13+5 because you do not want to count 21 twice
