Write the general polynomial p(x) if its only zeros are 1 4 and -3 with multiplicites 3 2 and 1 respectively what is the degree
Answer:
The 6th degree polynomial is [tex]p(x) = (x-1)^3(x-4)^2(x+3)[/tex]
Step-by-step explanation:
Zeros of a function:
Given a polynomial f(x), this polynomial has roots [tex]x_{1}, x_{2}, x_{n}[/tex] such that it can be written as: [tex]a(x - x_{1})*(x - x_{2})*...*(x-x_n)[/tex], in which a is the leading coefficient.
Zero 1 with multiplicity 3.
So
[tex]p(x) = (x-1)^3[/tex]
Zero 4 with multiplicity 2.
Considering also the zero 1 with multiplicity 3.
[tex]p(x) = (x-1)^3(x-4)^2[/tex]
Zero -3 with multiplicity 1:
Considering the previous zeros:
[tex]p(x) = (x-1)^3(x-4)^2(x-(-3)) = (x-1)^3(x-4)^2(x+3)[/tex]
Degree is the multiplication of the multiplicities of the zeros. So
3*2*1 = 6
The 6th degree polynomial is [tex]p(x) = (x-1)^3(x-4)^2(x+3)[/tex]
find the value of the trig function indicated
Answer:
[tex]\cos(\theta)=\frac{4}{5}[/tex]
Step-by-step explanation:
Step 1:
Let us find the missing side. We know this is a right triangle, so we can use the pythagorean thereom to find the last side. Let us set 12 as variable a, 20 as variable c, and the unknown side as variable b.
[tex]a^2+b^2=c^2\\12^2_b^2=20^2\\b^2=400-144\\b^2=256\\b=\pm16[/tex]
We do know that a length can never be negative, so the side b would be 16.
Step 2:
According to SOHCAHTOA, cosine is utilizes the adjacent and hypotenuse of the given angle theta. Let us write the equation:
[tex]\cos(\theta)=\frac{adjacent}{hypotenuse} \\\\\cos(\theta)=\frac{16}{20} \\\\\cos(\theta)=\frac{4}{5}[/tex]

5x - 4 + 2x = 3
please help
Answer:
x = 1
Step-by-step explanation:
First, combine like terms. Like terms are terms that share not only the same variable, but the same amount of that variable:
5x - 4 + 2x = 3
(5x + 2x) - 4 = 3
7x - 4 = 3
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. PEMDAS is the order of operation, and stands for:
Parenthesis
Exponents (& Roots)
Multiplications
Division
Addition
Subtraction
First, add 4 to both sides of the equation:
7x - 4 (+4) = 3 (+4)
7x = 3 + 4
7x = 7
Next, divide 7 from both sides of the equation:
(7x)/7 = (7)/7
x = 7/7 = 1
x = 1 is your answer.
~
Answer:
x = 1
Step-by-step explanation:
5x - 4 + 2x = 3
7x - 4 = 3 (add the Xs together)
7x = 7 (add seven to both sides)
x = 1 (divide both sides by 7)

On a coordinate plane, a straight line with a negative slope crosses the y-axis 1 time and the x-axis 1 time.
On a coordinate plane, an oval line crosses the y-axis 2 times and the x-axis two times.
On a coordinate plane, a line with an s curve crosses the y-axis 1 time and the x-axis 1 time.
Answer:
On a coordinate plane, an oval line crosses the y-axis 2 times and the x-axis two times.
Step-by-step explanation:
Vertical line test.
If you draw a vertical line, parallel to the y-axis and it crosses a line or shape twice, it is not a function.
On a coordinate plane, an oval line crosses the y-axis 2 times and the x-axis two times. The correct option is C.
What is a function?A function is defined as the expression that set up the relationship between the dependent variable and independent variable. A graph is the representation of the data on the vertical and horizontal coordinates so we can see the trend of the data.
On taking the vertical line test it is observed that If you draw a vertical line, parallel to the y-axis and it crosses a line or shapes twice, it is not a function.
Therefore, on a coordinate plane, an oval line crosses the y-axis 2 times and the x-axis two times. The correct option is C.

Since the numbers are the same, you are allowed to add the exponents.
[tex] {7}^{7} \times {7}^{3} = {7}^{10} [/tex]
Answer:
[tex]7^{10}[/tex]
Step-by-step explanation:
The laws of exponents state that if two terms share a base they can be simplified. Specifically, the product exponent law says that if 2 like bases are being multiplied then the exponents can be added together. So, because the two bases are like and 7+3=10, the final answer is [tex]7^{10}[/tex].

Find the angle
Answer:
x = 50.8°
Step-by-step explanation:
We are given:
1.) Angle x
2.) Side opposite to angle x
3.) Hypotenuse
Therefore to find the angle x, we will use the sin inverse:
Sin(x) = Opposite / Hypotenuse
Sin(x) = 6.2/8
x = Sin⁻¹(6.2/8)
x = 50.8°

A bacteria population is going exponentially with a growth factor of 1/6 each hour. By what growth factor does the population change each half an hour select all that apply?
Answer:
The bacteria population will change with a growth factor of 1/12 for every half an hour or 1/12 per 30 minutes. (I don't know what the options are, but anything related to the answer I gave should be right.)
Step-by-step explanation:
Simple mathematics should get you the right answer. Here we are dealing with a fraction in a fraction. The first scenario should look like this: 1/6 / 1. Basically, that looks like one-sixth over one. Obviously, if we divide 1/6 by 1, we would get 1/6 itself again and we want to know what growth factor the population changes by for every half an hour. There are 30 minutes in half an hour and 60 minutes in one hour. Let's use the simplified terms to our advantage. Now, our first scenario should look like this: 1/6 / 60. Looks better now doesn't it? (Check the linked image to see the full scenario and how I did it in this next part.) For me, I divided 60 by 30 to get the scale factor, which is 2, then I divide 2 by 1/6 to get 1/12. Finally, we have 1/12 per half an hour! If I am wrong, please let me know and I hope this helps! :D

Henry is buying bagels for a family gathering. Each bagel costs $0.75. Answer the
questions below regarding the relationship between the total cost and the number of
bagels purchased.
Answer:
0.75x=(total cost)
Step-by-step explanation:
Answer:
The independent variable, x, represents the number of bagels purchased, and the dependent variable is the total cost of the bagels, because the total cost of the bagels depends on the number of bagels purchased.
A function relating these variables is A(x) =0.75x .
So A(12) = 9, meaning 12 bagels will cost 9 dollars.

The graph of the linear equation can be seen below.
Which graph represents the given function?
Here we have the linear function:
y = 5x + 3
To graph this, we need to find two points on the equation and then connect them with a line.
By evaluating in 0 we get:
y = 5*0 + 3 = 3
So the point (0, 3) is on the line.
By evaluating on 1 we get:
y = 5*1 + 3 = 8
So we have the point (1, 8).
Now we just plot them and connect them with a line, the graph is the one below.
