The polynomial P in lowest degree given the following roots: 4, -3, 4i is x^3 - (4i+1)x^2+4(i-3)x + 48i

Given the roots of a polynomial such as 4, -3, 4i. The equivalent factors of the polynomial will be x-4, x+3 and x-4i

Taking the product of the factors

P(x) = (x-4)(x+3)(x-4i)

P(x) = (x^2+3x-4x-12)(x-4i)

P(x) = (x^2 - x - 12)(x-4i)

P(x) = x^3-4x^2i-x^2+4xi-12x+48i

P(x) = x^3 - (4i+1)x^2+4(i-3)x + 48i

Hence the polynomial P in lowest degree given the following roots: 4, -3, 4i is x^3 - (4i+1)x^2+4(i-3)x + 48i

Answer:

C x<4

Step-by-step explanation:

get x by itself

-x>3-7

-x>-4

dividing by a negative number with inequalities means you have to flip the sign

x<4

You get vertical asymptotes because the x-value causes you to try to divide by 0.  

If you look at the denominator, the x-values of 0, 1, and -5 all will make the denominator equal to 0, making the whole function explode.  

    You find these by solving  3x(x-1)(x+5)=0.

That's your answer: 0, 1, and -5

Answer:

-7/8a-1/6

Step-by-step explanation:

The points not included in the graph are A: (2.5,3), B: (2.0, 3), C: (3.0, 4) and D: (3.5, 5)

From the question, we have the following parameters that can be used in our computation:

Initial service charge = $2

Additional charges = $1 per hour

This means that the charges after x hours is

f(x) = Initial service charge + Additional charges * x

Substitute the known values in the above equation, so, we have the following representation

f(x) = 2 + x

Using the given points, we have

f(2.5) = 2 + 2.5 = 4.25

f(2.0) = 2 + 2.0 = 4.0

f(3.0) = 2 + 3.0 = 5.0

f(3.5) = 2 + 3.5 = 5.5

This means that all of the points are not in the graph

Answer:

The equation of a line is written in the form y=mx+b. “m” is the slope and “b” is the y-intercept. With the given slope, the equation so far is y=-4x+b. To find the value of b, substitute the given point.

-12=-4(10)+b

-12=-40+b

28=b

So, the equation of the line is y=-4x+28.

Step-by-step explanation:

We have 24 inches of space, we want to find how many 3/8 inches notebooks fit in that. I'm assuming 24 inches of space is the width.

Therefore:

24÷[tex]\frac{3}{8}[/tex]

or 24×[tex]\frac{8}{3}[/tex]

= 192/3

D. 29.75

Step-by-step explanation:

To determine the mean, you must add up all the numbers and then divide that number by how many numbers you added.

Here,

21 + 23 + 35 + 40

= 119

You added 4 numbers (21, 23, 35, 40),

so, 119 / 4

= 29.75

Answer:

0.325 inches per hour

Step-by-step explanation:

0.65 ft/day must be converted to inches/hr.  One approach follows:

0.65 ft     1 day        12 hr

---------- * ----------- * ---------- = 0.325 in/hr

  day       24 hr        1 ft

The growth rate is 0.325 inches per hour

Answer:

The diameter is 2 times the radius.

D=2r

Substitute 20 as the diameter and solve for r.

20=2r

Divide both sides by 2.

10=r

So, the radius is 10 centimeters.

Answer:

9000 grams

Step-by-step explanation:

1 kilogram = 1000grams

9 kilograms = 9000 grams

Answer: d) 19.8 pounds

Step-by-step explanation:  (1000)(9 kilograms) = 9000 grams. And yes 9 kilograms does equal to 9000 grams but that isn't the correct answer. Also kilograms isn't equal to b) 9000 ounces, and c) 19.8 ounces even though ounces are apart of the household measurement system because 9 kilograms is equal to 317.466 ounces. (35.274)(9 kilograms) = 317.466 ounces. So the obviously only correct answer is d) 19.8 pounds because 9 kilograms is equal to 19.8 pounds. (2.205)(9 kilograms) = 19.8416 pounds.

Answer:

It should be -3.125%

Step-by-step explanation:

(124 - 128)/128 × 100

-4/128 × 100 = -3.125%

By a change of units, we will get that 108 mi/h = 158.4 ft/s

Here we want to transform 108 mi/h to feet per second.

Then we will use two relations:

Then we can just transform as:

108mi/h = (108*5,280 ft)/h = 570,240 ft/h

570,240 ft/h = 570,240 ft/(3,600 s) = 158.4 ft/s

So we have:

108 mi/h = 158.4 ft/s

Answer:

45

Step-by-step explanation:

In an inverse variation situation, we have mathematical relationship between two variables which can be expressed by an equation in which the product of two variables is equal to a constant.

So in this case: x*y is a constant

since x=9 and y=5 so

xy = 45

the constant of variation is 45

For inverse function, we usually write it as [tex]y = \dfrac{45}{x}[/tex]

The required solution of the value of the constant of variation is 45.

Inverse variation is the relationships between variables that are represented in the form of y = k/x, where x and y are two variables and k is the constant value. It states if the value of one quantity increases, then the value of the other quantity decreases.

Given:

for an Inverse variation, y=5 when x=9

According to given question we have

Relationship between two variables which can be expressed by an equation in which the product of two variables is equal to a constant.

x×y  =constant

x×y  =k

Where k is a constant.

By put the value of

y=5 when x=9.

k= 9×5

k=45

Therefore, the required solution of the value of the constant of variation is 45.
