Answer:
f(x) = (x -2)(x -1+3i)(x -1-3i)
Step-by-step explanation:
You can use synthetic division to find the remaining quadratic factor in the cubic. Then any of the usual means of solving the quadratic will help you find its linear factors.
In the attached, I show the synthetic division, the factoring to real numbers, and the solution that finds the complex linear factors by completing the square.
Of course, you know that for zeros a, b, and c, the linear factors are ...
f(x) = (x -a)(x -b)(x -c)
Here, we have a=2, b=1-3i, c=1+3i.
f(x) = (x -2)(x -1+3i)(x -1-3i)
Answer:
in a region with a letter
Step-by-step explanation:
For a certainty, then probability is 1.
That means sum of probability of all events in the sample space.
This means P(A)+P(B)+P(C)+P(D)=1
This is equivalent to:
P(A or B or C or D)=1
Hence for certainty, the region must be:
A or B or C or D
So the correct answer is in a region with a letter.
When a customer has a 6 pound Chihuahua, the cost that will be charged is $5.00.
<h3>How to calculate the cost?</h3>
a. If a customer has a 6 pound Chihuahua, how much would you charge?
It should be noted that from the information given, for dogs that weigh 0 to 15 pounds, the amount charged is $5.00.
b. If a customer has a 65 pound Labrador, how much would you charge?
It should be noted that for dogs over 45 pounds, the amount that's charged is $9.00
There, the amount charged will be $9.00.
