"Sketch a possible graph for a negative Quintic polynomial with one real zero." Can anyone explain how this is done? And if possible provide a graph?

Answer:

- The equation is: [tex]\frac{249}{2}=2(x+\frac{17}{4})+2x[/tex]

- The width of the postage stamp is 29 milimeters.

- The length is 33.25 milimeters.

Step-by-step explanation:

1. The length ([tex]y[/tex]) is [tex]4^{\frac{1}{4} }mm=\frac{17}{4}mm[/tex] longer than the width ([tex]x[/tex]):

[tex]y=x+\frac{17}{4}[/tex]

2. The perimeter is [tex]124^{\frac{1}{2}}mm=\frac{249}{2}mm[/tex].

3. The perimeter of a rectangle is:

[tex]Perimeter=2Length+2Width[/tex]

4. Substitute values:

[tex]\frac{249}{2}=2(x+\frac{17}{4})+2x[/tex]

5. Solve for the width [tex]x[/tex]:

[tex]\frac{249}{2}=2x+\frac{34}{4}+2x\\x=\frac{116}{4}\\x=29[/tex]

6. Calculate the length:

[tex]y=x+\frac{17}{4}\\y=29+\frac{17}{4}\\y=33.25[/tex]

The width and length of the postage stamp are calculated by formulating and solving an equation based on the given perimeter and the relationship between the length and width. The width is found to be 29 mm, and the length is 33.25 mm.

The subject of this question is Mathematics and it's related to the concept of the perimeter of a rectangle. If we denote the width of the postage stamp as 'W' (in millimeters), then it's length will be 'W + 4.25' millimeters because it's stated in the problem that the length is 4.25 mm longer than the width.

The perimeter of a rectangle (which is the shape we can assume for a postage stamp) is calculated as follows: Perimeter = 2(Length + Width). Substituting the value for length that we've assigned, we get this equation:

124.5 = 2[(W + 4.25) + W]

Solving this equation step-by-step will lead you to the answer. First, distribute the 2 into the parentheses which gives: 124.5 = 2W + 8.5 + 2W. Combine like terms to simplify: 124.5 = 4W + 8.5. Then, subtract 8.5 from both sides of the equation: 116 = 4W. Lastly, divide by 4 to find 'W': W = 29 mm. Therefore, the width of the postage stamp is 29 mm, and the length is 29 mm + 4.25 mm = 33.25 mm.

We have to give that,

An expression to simplify,

12r - 18 = 13r + 18

Now, We can simplify the expression as,

12r - 18 = 13r + 18

Subtract 12r on both sides,

12r - 18 - 12r = 13r - 12r + 18

-3x = -15      divide both sides by (-3)

-3x:(-3)=-15:(-3)

x = 5

Answer:

The answer is b, 5

Step-by-step explanation:

-3x = -15

(it sometimes helps to flip it, so that's what I'm going to do here to help it to make more sense)

x(-3) = -15

x(-3) devided by (-3) = -15 devided by (-3)

when you devide a negitive by a negative the answer will be positive

the absolute value of 15 devided by three is 5

your answer is a positive five, or just 5

Answer:

The least value of n is, 9.

Step-by-step explanation:

Let n be the number of sheep in Integer.

Mary(M) owned the number of sheep is n i.e, M = n sheep

Sam(S) had exactly four times as many sheep as Mary , i.e, S = 4 n sheep

As per the given condition Mary buys 17 extra sheep

Now, Mary has total number of sheep, M = n +17 sheep

And Sam sells 8 of his sheep that means he has now,

[tex]S = 4n -8[/tex]

But, Sam still has more sheep than Mary i.e,  [tex]4n-8 > n+17[/tex]

Solve an inequality: [tex]4n-8 > n+17[/tex]

Add 8 both sides we get;

[tex]4n-8+8>n+17+8[/tex]

Simplify:

[tex]4n>n+25[/tex]

Now, subtract n from both the side, we get;

[tex]4n -n>n+25-n[/tex]

Simplify:

[tex]3n>25[/tex] or [tex]n>\frac{25}{3}=8.33333333[/tex]

Since n is the number of sheep in integer,

then the least value of n is, 9.

78.5 m^2

78.54 m² is your answer. So to recap, a goat tethered to a stake in the ground with a 5 m rope has 78.54 meters to graze.

We get this answer by putting the information into an equation. We know that a circle has 360° (360 degrees) and so when we see the problem say that the goat can graze 360 degrees around the stake, we instantly know it's talking about a circle. Look at the question, it's asking about the area of the circle. Now we can make an equation to find the area of this circle.

The area of a circle is A = πr²

That's Area = Pi times Radius squared.

We'll use 3.14 as substitute for Pi. The radius was given to us, it is 5 m. Put the information into the formula.

A = 3.14 * 5²

Now we do the order of operations. In the order of operations, we have no parenthesis to work with, but we do have an exponent. So we take 5 to the second power, (5² = 5 * 5) and we update our problem.

A = 3.14 * 25

Now we finish the problem by multiplying 3.14 and 25.

A = 78.54

We're not entirely done. Now we include our units of measurement. In this case, we were using m for meters. When solving for area, the unit is always squared in the final answered. So this would be our final answer:

A = 78.54 m²

Answer:

a-bi

Step-by-step explanation:

If a quadratic equation lx^2+mx+n=0 has one imaginary root as a+bi then the other root is the conjugate of a+bi = a-bi

Because we have l, m and n are real numbers and they are the coefficients.

Sum of roots = a+bi + second root = -m/l

When -m/l is real because the ratio of two real numbers, left side also has to be real.

Since bi is one imaginary term already there other root should have -bi in it so that the sum becomes real.

i.e. other root will be of the form c-bi for some real c.

Now product of roots = (a+bi)(c-bi) = n/l

Since right side is real, left side also must be real.

i.e.imaginary part =0

bi(a-c) =0

Or a =c

i.e. other root c-bi = a-bi

Hence proved.

It is true in this case, because you are trying to find the distance between two points. That also means you are trying to find the difference between two points, and to find the difference, you subtract. That is why what Brittany says is true.

Absolute value is always positive because absolute value represent distance and distance can not be negative.

Yes it is true, To determine the distance between 180 and 34, you can just subtract 180 - 34.

Since, absolute value is represent distance between two points

and absolute value is always greater or equal to zero.

a. 2 unpopped out of 75 kernels  = [tex]\frac{2}{75}[/tex]

                                                       = 2 : 75  This is not a match

b. 2 unpopped out of 200 kernels = [tex]\frac{4}{200}[/tex]

                                                         = [tex]\frac{1}{50}[/tex]

                                                         = 1 : 50   This is same

Let's find the slope of our line using the slope formula:

[tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

where

[tex]m[/tex] is the slope of the line

[tex](x_{1},y_{1})[/tex] are the coordinates of the first point on the line

[tex](x_{2},y_{2})[/tex] are the coordinates of the second point

From the graph we can get the points (-2, 1) and (2, -1), so [tex]x_{1}=-2[/tex], [tex]y_{1}=1[/tex], [tex]x_{2}=2[/tex], and [tex]y_{2}=-1[/tex]. Let's replace the values in our formula to find [tex]m[/tex]:

[tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

[tex]m=\frac{-1-1}{2-(-2)}[/tex]

[tex]m=\frac{-2}{2+2}[/tex]

[tex]m=\frac{-2}{4}[/tex]

[tex]m=-\frac{2}{4}[/tex]

[tex]m=-\frac{1}{2}[/tex]

The slope of the graph of the linear function is [tex]-\frac{1}{2}[/tex]; since [tex]-\frac{1}{2}[/tex] is a negative number, the slope of the graph is negative.

The rate of change is of 0.25 lbs / person

Step-by-step explanation:

According to my research the formula for the Rate of Change is the following

[tex]\frac{y2 - y1}{x2 - x1}[/tex]

In this situation we can use y for lbs and x for people. Since all the information was given to us in the question we can just plug the values into the formula above and solve for the rate of change.

[tex]\frac{17lbs-9lbs}{68-36} = \frac{8lbs}{32people} = 0.25lbs/person[/tex]

So we can see that the rate of change is of 0.25 lbs / person

Let the angles are x, y and z.

Let the smallest angle is x

one angle is 78 degrees more than the smallest angle.⇒ y = x + 78 → (1)

the third angle is 4 times as large as the smallest angle. ⇒ z = 4 x → (2)

we should know that the sum of the angles of the triangle = 180°

∴ x + y + z = 180 →(3)

substitute from (1) and (2) at (3)

∴ x + ( x +78) + (4x) = 180

∴ 6x = 180 - 78 = 102

∴ x = 102 ÷ 6 = 17°

∴ y = 17 + 78 = 95°

∴ z = 4x = 68°

So, the measures of all three angles are 17°, 95° and 68°
