Write a possible third degree polynomial with integer coefficient that have zeros: 1 2i, -4. Assume the leading coefficient to be 1
Answer:
The polynomial is:
[tex]p(x) = x^3 + 2x^2 - 3x + 20[/tex]
Step-by-step explanation:
A third degree polynomial can be written in function of it's zeros [tex]x_1, x_2, x_3[/tex] the following way:
[tex]p(x) = a(x - x_1)(x - x_2)(x - x_3)[/tex]
In which a is the leading coefficient.
Integer coefficient that have zeros: 1+2i, 1-2i, -4
Leading coefficient: 1
So
[tex]p(x) = 1(x - (1+2i))(x - (1-2i))(x - (-4))[/tex]
[tex]p(x) = (x - 1 -2i)(x - 1 + 2i)(x + 4)[/tex]
[tex]p(x) = ((x-1)^2 - (2i)^2)(x + 4)[/tex]
[tex]p(x) = (x^2 - 2x + 1 - 4i^2)(x + 4)[/tex]
Since [tex]i^2 = -1[/tex]
[tex]p(x) = (x^2 - 2x + 1 + 4)(x + 4)[/tex]
[tex]p(x) = (x^2 - 2x + 5)(x + 4)[/tex]
[tex]p(x) = x^3 + 4x^2 - 2x^2 - 8x + 5x + 20[/tex]
[tex]p(x) = x^3 + 2x^2 - 3x + 20[/tex]

The function f(x) = –0.5x2 + 16x – 96 can be used to trace the path of a rocket, where the x-axis represents the ground and the y-axis measures the height of the rocket. The mathematical domain of the function is all real numbers.
The reasonable domain of the function is when 8 ≤ x ≤ x greater than or equal to eight but less than or equal to what value?
Answer:
24
Step-by-step explanation:
Put it in Desmos, and it’ll show you
The reasonable domain of the function is 8 ≤ x ≤ 24.7.
What is a function?A function has an input and an output.
A function can be one-to-one or onto one.
It simply indicated the relationships between the input and the output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
f(x) = -0.5x² + 16x – 96
The function represents the height of a rocket as a function of its horizontal position.
It is reasonable to assume that the rocket is launched from the ground
(x = 0) and that it has some minimum height (above ground level) before it is launched.
Now,
We can find this minimum height by finding the vertex of the parabola, which is given by.
x = -b / (2a)
where a = -0.5 and b = 16.
Plugging in these values, we get.
x = -16 / (2(-0.5))
x = 16
Now,
The vertex occurs at x = 16.
To find the minimum height, we can plug this value into the function.
f(16) = -0.5(16)² + 16(16) - 96
= 128
Therefore,
The rocket has a minimum height of 128 feet above ground level before it is launched.
To find the reasonable domain of the function.
Since the rocket is launched from the ground at x = 0 and has a minimum height of 128 feet, it is reasonable to assume that the rocket will remain above ground level for all values of x greater than or equal to 8, since the rocket must clear a height of 128 feet by the time it reaches x = 8.
Now,
We can find the x-value where the rocket reaches ground level
(i.e., its height is zero) by setting f(x) = 0.
Solving for x.
-0.5x² + 16x - 96 = 0
Using the quadratic formula.
x = ( -16 ± √(16² - 4(-0.5)(-96)) ) / (2(-0.5))
x = ( -16 ± √(1216) ) / (-1)
x ≈ 24.7 or x ≈ 7.3
Since the rocket is launched from the ground at x = 0, it is not reasonable to consider values of x less than 0.
Therefore,
The reasonable domain of the function is 8 ≤ x ≤ 24.7
This means,
The rocket will remain above ground level for all values of x between 8 and approximately 24.7.
Thus,
The reasonable domain of the function is 8 ≤ x ≤ 24.7.

Passing through (4,5) and PARALLEL to y=2x-4
A PARALLEL line has the same angular coeficient, so:
[tex]f(x) = 2x+b[/tex]
[tex]f(4) = 5[/tex]
[tex]5 = 2\cdot 4 +b[/tex]
[tex]b = 5-8[/tex]
[tex]b = -3[/tex]
The line asked is:
[tex]f(x) = 2x-3[/tex]
Answer:
-2x+y=-3
Step-by-step explanation:
Choose a point (4,5) that the parallel line will pass through.
Find the slope m=2
To find an equation that is parallel to y=2x-4 the slopes must be equal. Using the slope of the equation, find the parallel line using the point-slope formula.
y-y1=m(x-x1) if m=2 and x1=4 and y1=5
y-5=2(x-4)
y-5=2x-8
Solve for y --- > y=2x-3
