Answer:
[tex]P(x) = x^3 - 10x^2+ 34x-40[/tex]
Step-by-step explanation:
Given
[tex]p =1[/tex] -- Leading coefficient
[tex]Zeros: 4\ and\ 3 - i[/tex]
Required
Determine the polynomial
Represent the zeros with a and b
Such that
[tex]a = 4[/tex]
[tex]b = 3 - i[/tex]
The polynomial is:
[tex]P(x) = p * (x - a) * (x - b)[/tex]
[tex]P(x) = 1 * (x - 4) * (x - (3 - i))[/tex]
However, to solve further: We need to symmetrise over 3-i and its conjugate
[tex]P(x) = 1 * (x - 4) * (x - (3 - i))* (x - (3 + i))[/tex]
[tex]P(x) = (x - 4) * (x - (3 - i))* (x - (3 + i))\\\\[/tex]
To define a suitable function, the expression becomes
[tex]P(x) = (x - 4) * ((x - 3)^2+1)[/tex]
[tex]P(x) = (x - 4) * ((x - 3)(x - 3)+1)[/tex]
[tex]P(x) = (x - 4) * (x^2 - 6x + 9+1)[/tex]
[tex]P(x) = (x - 4) * (x^2 - 6x +10)[/tex]
Open bracket
[tex]P(x) = x^3 - 6x^2 +10x - 4x^2 + 24x-40[/tex]
[tex]P(x) = x^3 - 6x^2 - 4x^2+10x + 24x-40[/tex]
[tex]P(x) = x^3 - 10x^2+ 34x-40[/tex]

4. Write the ratio for cos M.
cos M = 24/25
cos M = 12/25
cos M = 24/7
cos M = 25/24
Answer:
24/25
Step-by-step explanation:
Hello There
[tex]cos = \frac{adjacent}{hypotenuse} [/tex]
The adjacent of M is 24 and the hypotenuse is 25 so
[tex]cosm = \frac{24}{25} [/tex]
Answer:
cos M= base/hypotenuse=KM/LM=24/25

Given f(x) =1 - 3/4x find the following.
a. f(-12) b. f(0) c. f(4)
Answer:
a. f(-12) = 10
b. f(0) = 1
c. f(4) = -2
Step-by-step explanation:
In order to find the function of each of these numbers, you just need to replace them in the function as x and then solve:
a. f(-12) = 1 - 3/4(-12)
- f(-12) = 1 - (-36/4)
- f(-12) = 1 + 9
- f(-12) = 10
b. f(0) = 1 - 3/4(0)
- f(0) = 1 - 0
- f(0) = 1
c. f(4) = 1 - 3/4(4)
- f(4) = 1 - 12/4
- f(4) = 1 - 3
- f4) = -2
Please help me out! (Find the measurements of the following angles. Fill in the blanks with your answer. Your answer should be numerical)
PLEASE HELP FAST! Which inequality is graphed below?
Answer:
I gotchu, it's A. x > -2
Step-by-step explanation:
The circle on the line is open so it means less than or greater than. If it was a close circle, it would be less than or equal to and vice versa. And the number is -2. The line excludes -2 but includes all numbers greater than that. So the answer would be A. x > -2
Answer:
a
Step-by-step explanation:
when the circle is open and not filled in means its not equal to and since -2 less than x, x=-3 or more

please answer with steps
Answer:
both of these.will be solved by angle sum property which states that sum of all interior angles is 180 degrees
in a
one angle is 30 degrees
other is right angle means 90 degrees
total sum of these angles is 120
total sum of all angle must be 180 degrees
so the third angle is 60 degrees
in b
one angle is 45 degrees
other is a right angle means 90 degrees
total sum of these angles is 135
total sum of all angles must be 180 degrees
so the third angle is 45 degrees
hope this helps
have a good day
thanks for points

The cook at a local restaurant makes a special raspberry iced tea. He uses 8 small containers of the rasberry tea base to make 2 quarts of iced tea. How many small containers of the tea base will he need to make 12 quarts of the iced tea
Answer: 48 small containers
Step-by-step explanation:
Let the amount of small containers of the tea base that he will need to make 12 quarts of the iced tea be represented by x.
The information given can be formed into an expression as:
8/x = 2/12
Cross multiply
2 × x = 8 × 12
2x = 96
x = 96/2
x = 48
Therefore, 48 small containers will be needed.

Is the probability of red a simple event, complement of a
simple event, or neither?
A. complement of a simple event
B. nelther
C. simple event
Answer:
Complement of an Event: All outcomes that are NOT the event. So the Complement of an event is all the other outcomes (not the ones we want). And together the Event and its Complement make all possible outcomes.

Triángulo equilátero
Triángulo isosceles
Triángulo escaleno
Triángulo equilátero = todos los 3 lados son congruentes ("equilátero" = lados iguales)
Triángulo isósceles = solo 2 lados son congruentes
Triángulo escaleno = todos los lados son diferentes
El triángulo que se muestra aquí es isósceles porque 2 de los lados tienen la misma longitud de 7 cm.
Which best describes the probability of the rolling a 7 on a number cube that is numbered from 1 through 6
Answer:
[tex]\huge\boxed{\text{Impossible}}[/tex]
Step-by-step explanation:
To find the probability of something happening, we find all the outcomes that can happen, find all the outcomes in which our criteria is met, and set that up as a fraction, where it's criteria met/total possible outcomes.
When we roll a 6-sided die, we will have 6 possible outcomes that we can roll.
1, 2, 3, 4, 5, and 6.
We can not roll anything except these 6! Since a die only has 6 sides, numbered 1-6, we will only roll these numbers.
7 is not in this list! It is impossible to roll a 7 on a die that only has 6 sides. Since 7 isn't even possible, it would be impossible to get a 7 on a 6-sided die.
Hope this helped!
