Based on the P's and Q's of this polynomial (The Rational Zero Theorem), which of the following could NOT be a zero of the polynomial 4x3 + 4x2 - 11x-6?

Answers

Answer:

Step-by-step explanation:

P are the factors of the last coefficient (6) and Q are the factors of the first coefficient (4). Since p is divided by q, we could have 3/1, 6/1, 2/1, and 1/1, but not 4/1 since 4 is not a factor of 6

What is the conjugate of each complex number?

What is the sum of the complex numbers? Show all work.

What is the sum of the conjugates of the complex numbers? Show all work.

Answers

Conjugate is just changing the sign on the imaginary number, so the conjugates here are 3+6i and 9-i

The sum of the original complex numbers is (3-6i)+(9+i)=12-5i

The sum of the conjugates is (3+6i)+(9-i)=12+5i

Write a function formula for g using the function f.
g(x)=

Write a function formula for f using the function g.
f(x)=

Answers

Answer:

g(x) = -f(x+3)

f(x) = -g(x-3)

Step-by-step explanation:

Transformations

Function f can be obtained by knowing function g and vice-versa.

Suppose we know the expression of function f. If we reflect f across the x-axis, we get function g but displaced 3 units to the right.

Thus, we only have to translate the reflected f 3 units to the left:

g(x) = -f(x+3)

Similarly, if g(x) is reflected across the x-axis and translated by 3 units to the right, we get f(x), thus:

f(x) = -g(x-3)

If you have five red balls and five blue balls in a jar what’s the probability of the first ball being red?

Answers

Answer:

red balls = 5

blue balls = 5

total balls = 5 blue+5 red

= 10

[tex]p(first \: ball \: being \: red) = \frac{red \: balls}{total \: balls} [/tex]

[tex]p(first \: ball \: being \: red) = \frac{5}{10} = \frac{1}{2} [/tex]

Answer:

Step-by-step explanation:

Total number of red balls = 5

Total number of blue balls = 5

Total number of balls in jar = 5 + 5

= 10

Probability of the first ball being red = total number of the red ball/total number of balls in the jar

= [tex]\frac{5}{10}[/tex]

= [tex]\frac{1}{2}[/tex]

Therefore, the probability of the first ball being red = [tex]\frac{1}{2}[/tex], 50% or 0.5 (in any way you are instructed to write it in)

Given the side lengths of 20,23 and 41, determine whether the triangle is acute, right, obtuse, or not a triangle.

Answers

Answer: Obtuse triangle

=====================================================

Explanation:

In this case, a triangle is possible since adding any two sides leads to a sum larger than the third side

20+23 = 43 is larger than 4120+41 = 61 is larger than 2323+41 = 64 is larger than 20

I'm using the triangle inequality theorem here.

----------------------------

To determine what kind of triangle we have, we'll use the converse of the Pythagorean theorem. Specifically, we'll use a corollary of it.

Consider a triangle with sides a,b,c. Let c be the longest side.

We have three possible cases:

If a^2+b^2 = c^2, then we have a right triangleIf a^2+b^2 > c^2, then the triangle is acute.If a^2+b^2 < c^2, then the triangle is obtuse.

For this problem, we have a = 20, b = 23, c = 41.

We see that a^2+b^2 = 20^2+23^2 = 929 and c^2 = 41^2 = 1681.

In short, a^2+b^2 = 929 and c^2 = 1681.

Since 929 < 1681, this means a^2+b^2 < c^2.

Therefore, this triangle is obtuse.

Perform the indicated operation and simplify the result, Leave your answer in factored form.

Factors for 54: 1, 2, 3, 6, 9, 18, 27, 54

It's 6.

The greatest common factor of the numbers 12 and 54 will be 6.

Given that:

Numbers, 12 and 54

The biggest chunk of the common factors is called the "Greatest Common Factor" (of two or more numbers).

The factors of the numbers 12 and 54 are calculated as,

12 = 2² x 3

54 = 2 x 3³

The value of the greatest common factor is calculated as,

GCF = 2 x 3

Answer:

x=22

Step-by-step explanation:

The interior angles of a triangle always add up to 180° so you will add the angles together and set them equal to 180° to solve for x. You will find that x should be equal to 22. Plug 22 into each equation to find the angle measure.
