Create a polynomial of degree 6 that has no real roots. Explain why it has no real roots. Is it possible to have a polynomial with an odd degree that has no real roots? Explain.

Answers

Create a polynomial of degree 6 that has no real roots.

y = ( x^2 + 4) ( x^2 +7 ) ( x^2+5)

Multiplying all the terms together

y =x ^6 + 16 x^4 + 83 x^2 + 140

Using the zero product property

0= x^2 +4 x^2+7 =0 x^2 + 5 =0 will each give a complex solution

x^2 = -4 x^2 = -7 x^2 = -5

This means x = 2i or -2i x = i sqrt(7) or -i sqrt(7) x = i sqrt (5) or - i sqrt(5)

These solutions can be in the form a+bi

Therefor it will have no real roots

y = x^6 + 16 x^4 + 83 x^2 + 140 has no real solutions

Complex solutions come in pairs, so an odd degree must have a real solution

Graph the intersection or union, as appropriate, of the solutions of the pair of linear inequalities

Answers

See graph below

To plot the graphs, we will assing values to x in order to get the corresponding values of y for each of the inequality:

let x = 0, 2, 4

x + y = 4

from the above: y = 4 - x

when x = 0

y = 4

when x = 2

y = 4 - 2 = 2

when x = 4

y = 4 -4 = 0

Linda's medicine bottlesays "If you will be driving, then youshould not take this medicine." What arethe inverse, converse, and thecontrapositive of this statement?

Answers

For two statements p and q, and the compounded statement "If p, then q", we have the following definitions for the inverse, converse, and contrapositive of this compounded statement:

inverse: If not p, then not q.

converse: If q, then p.

contrapositive: If not q, then not p.

So, for the presented statement, i. e., "If you will be driving, then you should not take this medicine" we have:

p: you will be driving

q: you should not take this medicine

Notice that:

not p: you will not be driving

not q: you may take this medicine

Then, using the above definitions, we write:

inverse: If you will not be driving, then you may take this medicine.

converse: If you should not take this medicine, then you will drive.

contrapositive: If you may take this medicine, then you will not be driving.

write the vertex form equation of the parabola with, vertex: (10,9), passes through: (12,-7)

Answers

Th equation of a parabola in its vertex form is;

y = a(x-h)² + k

(h,k) are the coordinates of the vertex and a is a constant

(h, k) = (10, 9)

substitute the above into the equation

y = a(x- 10)² + 9 -------------------(1)

Next is to find the value of a

substitute x=12 and y= -7 into equation (1)

-7 = a (12 - 10)² + 9

-7 - 9 = 4a

-16 = 4a

a = -4

The equation of the parabola will be formed by substituting a = -4 in equation (1)

y = -4(x - 10)² + 9

Answers

Using mathematical operations, we can conclude that the volume of the larger box is approximately 2,800 in³.

What are mathematical operations?The rules governing the order of operations specify the order in which multiple operations should be performed to solve an expression. Parentheses, Exponents, Multiplication, Division (from left to right), Addition, and Subtraction are the order in which the operations are performed (from left to right).

So, in the image, we can observe that the large box contains 6 boxes of cereals in front and possibly 8 boxes of cereals at the back.

In total, there are 16 small boxes in the big box.

Then, the volume of the larger box can be:

175 × 16 = 2,800 in³

Therefore, using mathematical operations, we can conclude that the volume of the larger box is approximately 2,800 in³.

Find the probability that a dart hits one of the shaded areas. Thewhite figure is a rectangle. Be sure to show all work.

Answers

SOLUTION

Given the question in the image, the following are the solution steps to answer the question.

STEP 1: Get the angles of the hexagon

The internal angles of an hexagon is given as:

[tex]\begin{gathered} \frac{180(n-2)}{n} \\ n=6\text{ since hexagon has 6 sides} \\ So\text{ we have:} \\ \frac{180(6-2)}{6}=\frac{180(4)}{6}=\frac{720}{6}=120\degree \end{gathered}[/tex]

Therefore each angle of the hexagon is 120 degrees.

STEP 2: find the length of the sides

We remove the right triangles as seen below:

Using the special right triangles, we have:

STEP 3: find the area of the extracted triangle above

[tex]\begin{gathered} b=1,h=\sqrt{3} \\ Area=\frac{1}{2}\cdot1\cdot\sqrt{3}=\frac{\sqrt{3}}{2}units^2 \end{gathered}[/tex]

Since there are two right triangles, we multiply the area by 2 to have:

[tex]Area=2\cdot\frac{\sqrt{3}}{2}=\sqrt{3}[/tex]

There are two triangles(both sides), therefore the total area of the shaded area will be:

[tex]\sqrt{3}\cdot2=2\sqrt{3}[/tex]

STEP 4: Find the area of the whole hexagon

[tex]\begin{gathered} Area=\frac{3\sqrt{3}s^2}{2} \\ s=hypotenuse\text{ of the right triangle}=2 \\ Area=\frac{3\sqrt{3}\cdot4}{2}=6\sqrt{3} \end{gathered}[/tex]

STEP 5: Find the probability

[tex]\begin{gathered} Probability=\frac{possible\text{ area}}{Total\text{ area}} \\ \\ Possible\text{ area}=2\sqrt{3} \\ Total\text{ area}=6\sqrt{3} \\ \\ Probability=\frac{2\sqrt{3}}{6\sqrt{3}}=\frac{1}{3}=0.3333 \end{gathered}[/tex]

Hence, the probability that the dart hits one of the shaded areas is approximately 0.3333

For (fog)(x) all you do is substitute the value of x for the value of (g)(x) because (fog)(x)=(f(g(x))), and vice versa for (gof)(x)!!

help meeeeeeeeee pleaseee !!!!!

Answers

The value of the composite function is as follows:

(gof)(5) = 6

How to find composite function?

The composite function can be solved as follows:

Composite functions are when the output of one function is used as the input of another.

In other words, a composite function is a function that depends on another function.

f(x) = x² - 6x + 2

g(x) = -2x

Therefore,

(gof)(5) =  g(f(5))

So we need to find g(f(x)) first.

Therefore,

g(f(x)) = -2(x² - 6x + 2)

g(f(x)) = - 2x² + 12x - 4

Therefore,

g(f(x)) = - 2x² + 12x - 4

(gof)(5) =  g(f(5)) = - 2(5)² + 12(5) - 4

(gof)(5) =  g(f(5)) = -50 + 60 - 4

(gof)(5) =  g(f(5)) = 6

The boats rate is ____ mph(Type an integer or decimal)

Answers

Let

x ----> rate of the boat in still water (mph)

y ---> rate of the current (mph)

Remember that

The speed is equal to dividing distance by the time

speed=d/t

d=speed*time

so

Upstream

speed=x-y

time=5 hours

100=(x-y)*5

x-y=20 --------> equation 1

Downstream

speed=x+y

time=4.5 h

100=(x+y)*4.5

x+y= 100/4.5 --------> equation 2

Adds equation 1 and equation 2

x-y=20

x+y= 100/4.5

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

2x=20+(100/4.5)

2x=190/4.5

x=190/9

x=21.11 mph

Which expression can be used to find the nth term in this sequence position: 1 2 3 4 5 nvalue of term: 2 5 10 17 26 ?

Answers

n²+1 where n is the position of the sequence

1) Considering the sequence (2,5,10,17,26,...) corresponding to 1,2,3,4,5,...

Let's figure out how that sequence grows:

5 -2 = 3

10 -5 = 5

17-10= 7

26-17= 9

And examining the differences from each difference we have:

5-3 =2

7-5 = 2

9-7 =2

2) So we can write the following table, where the first line is the sequence, then the positions, then the subtraction between them.

As it is a quadratic formula, we can write in the general form and then plug x=0

[tex]\begin{gathered} a_n=n^2 \\ 2\text{ 5 10 17 26} \\ 1\text{ 2 3 4 5 6 } \\ 1\text{ 4 9 25 36} \\ a_n=n^2+0n+1 \\ a_n=n^2+1 \end{gathered}[/tex]

3) Hence, to find the 6th term, for instance, we plug n=6 so

6²+1 = 31. So the formula to find the nth term is n² +1

3) Finally, the sequence is given by n² +1 where n is the position of the term.

Answers

2x^2 + 14x + 24 = 0

x^2 + 7x = -6

x^2 + 7x + 7^2/4 = 7^2/4 - 6

y = 2x + 1

We would equate both equations. We have

5x + 13 = 2x + 1

5x - 2x = 1 - 13

3x = - 12

x = - 12/3

x = - 4

y = 2(- 4) + 1 = - 8 + 1

y = - 7

One cubic foot holds 7.48 gallons of water, and 1 gallon ofwater weighs 8.33 pounds. How much does 6 cubic feet ofwater weigh in pounds? In tons?

Answers

We know that

• 1 cubic foot holds 7.48 gallons of water.

,

• 1 gallon of water weighs 8.33 pounds.

The given information is about ratios that we must use to find the answer. Remember that a ratio is a quotient between two magnitudes, that means each statement above represents a fraction which must multiply "6 cubic feet" in order to get the answer. As follows

[tex]6ft^3\cdot\frac{7.48gallons}{1ft^3}\cdot\frac{8.33lb}{1gallon}=\frac{6\cdot7.48\cdot8.33}{1}lb=373\text{.}85lb[/tex]

Therefore, 6 cubic feet weighs 373.85 pounds.

On the other hand, 1 ton is equivalent to 2000 pounds. Knowing this, we calculate

[tex]373.85lb\cdot\frac{1ton}{2000lb}\approx0.19ton[/tex]

Therefore, 6 cubic feet weighs about 0.19 tons.

Where (x1, y1) and (x2, y2) are points of the line.

Therefore, if we replace (x1, y1) by (5, -4) and (x2, y2) by (-1, 8), we get that the first step is to calculated:

y2 - y1 = 8 - (-4) = 8 + 4 = 12
