Derrick earned 1472 during the 4 weeks he had his summer job. If he earned the same amount each week, how much did he earn each week?

Answers

368 he earned each week.

During the 4 weeks he earned 1472, to be able to know the amount he earn each week. We simply, divide 1472 into 4 because in a month there are 4 weeks. In dividing,1472/4 = 368. The above answer is correct.
Hey there, 

The correct answer is $368. 

We know that Derrick earned 1472 during the 4 weeks he had his summer job. 

1472/4 = 368

What is the gcf of 16 20 24

Answers

Find the prime factorization of each number.
(Use divisibility rules, dividing up the number until you can't anymore.)

16 = 2 × 2 × 2 × 2
20 = 2 × 2 × 5
24 = 2 × 2 × 2 × 3

Multiply together any factors that they all share

2 × 2 = 4

Simplify the expression.

Answer:

D) 1,814, 400

Step-by-step explanation:

It is permutation.

nPr = n!/(n -r)!

Now we have to use the above formula and simplify.

12P10 = 12! / (12 - 10)!

= 12!/2!

=479001600/2

12P10 = 239,500,800

Now let's find 12P2

12P2 = 12!/(12 -2)!

= 12!/10!

= 479001600 / 3628800

12P2= 132

Now we have to divide 12P10 by 12P2

= 239500800/132

= 1,814,400

This will helpful.

Thank you.

Answer:

1814400

Step-by-step explanation:

We are given the following expression and we are to simplify it:

\frac {_(12) P_(10) } {_(12) P_2}

The formula for solving the permutation is:

nPr = \frac {n!} { (n-r)! }

Substituting the given values in the formula one by one.

12P10 = \frac {12!} {(12-10)!} = \frac {12!} {2!} =239500800

12P2 = \frac {12!} {(12-2)!} = \frac {12!} {10!} = 132

Now dividing the two values to get:

(_(12)P_(10))/(_(12)P_2) = (239500800)/(132) = 1814400

The correct answer is B


If f(x) is a third degree polynomial function , how many distinct complex roots are possible

Answers

Answer:

Zero complex roots or two complex roots.

Step-by-step explanation:

First of all, we have to know that complex roots can happen only in pairs, because they are based on the square root of a negative number.

On the other hand, a third degree polynomial can only have 3 roots as solution, because the degree of the polynomial specifies how many roots would have.

So, if we only can have 3 roots, and complex roots can only happen in pairs, then f(x) would have zero complex roots or two complex roots only, those are the unique scenarios.
the answer would be 0 or 2
