Find a possible formula for a fourth degree polynomial g g that has a double zero at 1 1 g(−4)=0 , g(5)=0 , and g(0)=−6

Answers

Answer 1
There's a double zero at 11, so that means (x-11)^2 is a factor

g(-4) = 0 so x+4 = 0 meaning that (x+4) is a factor
g(5) = 0 so x-5 = 0 meaning that (x-5) is a factor

all together, we have

(x-5)*(x+4)*(x-11)^2

let's expand this out

(x-5)*(x+4)*(x-11)^2
(x^2-x-20)*(x^2-22x+121)
x^2(x^2-22x+121) - x(x^2-22x+121) - 20(x^2-22x+121)
x^4-22x^3+121x^2-x^3+22x^2-121x-20x^2+440x-2420
x^4-23x^3+123x^2+319x-2420

This is multiplied by some constant k such that

k*(x^4-23x^3+123x^2+319x-2420) = -6

where plugging in x = 0 leads to -6

Let's plug in x = 0 and find out what happens with k

k*(x^4-23x^3+123x^2+319x-2420) 
k*(0^4-23*0^3+123*0^2+319*0-2420)
k*(-2420)
-2420k

So -2420k = -6 leads to k = 3/1210

Therefore, the equation is [tex]y = \frac{3}{1210}(x^4-23x^3+123x^2+319x-2420)[/tex]
Answer 2

The fourth degree polynomial g(x) with a double zero at x=1, zeros at x=-4 and x=5, and satisfying g(0)=-6 is g(x) = 3/10(x-1)²(x+4)(x-5).

A possible formula for a fourth degree polynomial g(x) with specific characteristics. The polynomial must have a double zero at x=1, zeros at x=-4 and x=5, and must satisfy g(0)=-6.

Since the polynomial has a double zero at x=1, we can represent that part of the polynomial as (x-1)². The other two zeros at x=-4 and x=5 give us factors of (x+4) and (x-5) respectively. Multiplying these factors gives us a polynomial that satisfies the zero requirements: (x-1)²(x+4)(x-5).

Now, we need to find the constant k that will make the polynomial satisfy g(0) = -6. We set up the equation using the known factors:
k(x-1)²(x+4)(x-5) and substitute x with 0 to solve for k. This gives us k(0-1)²(0+4)(0-5) = -6. Solving for k, we find k = 3/10.

Therefore, the formula for the polynomial g(x) is g(x) = 3/10(x-1)²(x+4)(x-5).

The correct option is 2.

Step-by-step explanation:

It is given that triangles ABC and PQR are similar triangles.

The sides of the triangle ABC are AB = c, BC = a, and AC = b. Triangle PQR has sides PQ = r, QR=p and PR=q.

If two triangles are similar, then their corresponding sides proportional.

Since ABC and PQR are similar triangles, therefore

[tex]\frac{AB}{PQ}=\frac{BC}{QR}=\frac{AC}{PR}[/tex]

[tex]\frac{c}{r}=\frac{a}{p}=\frac{b}{q}[/tex]

It can be written as

[tex]\frac{c}{r}=\frac{b}{q}[/tex]

[tex]\frac{a}{p}=\frac{b}{q}[/tex]

Therefore b:q is equal to c:r or a:p. Option 2 is correct.

What is the 40th term of the arithmetic sequence?

21,18,15,12,9....

A: -99
B: -96
C: 6
D: 138

Answers

We start off with 21 as the first term. So a1 = 21

The common difference is d = -3 because we subtract 3 each time to get from one term to the other (eg: 21 to 18 is minus 3)

The nth term of an arithmetic sequence is found by using this formula

an = a1 + d(n-1)

let's plug in the values we have so far to get

an = 21 + (-3)(n-1)
an = 21 - 3(n-1)
an = 21-3n+3
an = -3n+24

Why do this? Well it's helpful so we can find any term in the formula we want. In this case, we want the 40th term. So just plug in n = 40 from here and you're done

an = -3n+24
a40 = -3*40+24
a40 = -96

pointing you to the answer of choice B) -96

The 40th term of the arithmetic sequence 21,18,15,12,9.. is -96

using Arithmetic progression formula,

a = first term = 21

common difference =  d = 18 - 21 = - 3

Therefore,

aₙ = a + (n - 1)d

a₄₀ = 21 + (40 - 1)-3

a₄₀ = 21 +(39)(-3)

a₄₀ = 21 - 117

a₄₀ = -96

Nine wolves, eight female and one male.

We have to release three at a time also the male wolf is to be in the first released group and order does not matter

Then we have to choose 2 female wolves out of 8

as the order does not matter so we have to use combination

Hence, it is given as:

[tex]8_C_2=\dfrac{8!}{2!\times (8-2)!}\\\\8_C_2=\dfrac{8!}{2!\times 6!}\\\\8_C_2=28[/tex]

Identify the type of conic section that has the equation 9x^2+ 16y^2 = 144 and identify its domain and range.

Answers

Answer:

B ) ellipse.Domain: { -4 ≤ x ≤ 4 }Range: { -3 ≤ y ≤ 3 }

posted whole test on jiskha under RandomSophomore

The equation [tex]\(9x^2 + 16y^2 = 144\)[/tex] represents an ellipse. Its domain is \([-4, 4]\) and its range is \([-3, 3]\).

The equation [tex]\(9x^2 + 16y^2 = 144\)[/tex] represents an ellipse. To identify its domain and range, we need to understand its shape and orientation.

Step 1: Standard Form of an Ellipse

The standard form of an ellipse with its center at the origin is [tex]\( \frac{x^2}{a^2} + \frac{y^2}{b^2} = 1 \)[/tex], where \( a \) and \( b \) are the semi-major and semi-minor axes lengths, respectively.

Step 2: Compare Equations

Comparing the given equation [tex]\( 9x^2 + 16y^2 = 144 \)[/tex] with the standard form, we see that [tex]\( a^2 = \frac{144}{9} = 16 \)[/tex] and [tex]\( b^2 = \frac{144}{16} = 9 \).[/tex]

Step 3: Determine Axis Lengths

This means the semi-major axis length \( a \) is [tex]\( \sqrt{16} = 4 \)[/tex]and the semi-minor axis length \( b \) is [tex]\( \sqrt{9} = 3 \).[/tex]Step 4: Shape of the Ellipse

Since \( a > b \), the ellipse is stretched more horizontally than vertically, meaning it's wider than it is tall.

Step 5: Domain and Range

The domain of the ellipse is determined by the values of \( x \) and the range by the values of \( y \). For this ellipse, the \( x \)-values vary from \( -4 \) to \( 4 \) (domain), and the \( y \)-values vary from \( -3 \) to \( 3 \) (range).

Therefore, the domain is \([-4, 4]\) and the range is \([-3, 3]\).

To borrow money, you pawn your guitar. Based on the value of the guitar, the pawnbroker loans you $960. One month later, you get the guitar back by paying the pawnbroker $1,472. What annual interest rate did you pay? Round to the nearest tenth of a percent. ...?

Answers

Here is the solution of the given problem above. 
Given that the pawnbroker loans you $960, and a month later, you will be paying $1,472, we will find if how much is the annual interest rate.
Firstly, we need to deduct 960 from 1,472 and this gives us $512. $512 of 1,472 is 0.35%. We multiply 0.35% by 12 (annual 12 months) and the result is 4.17%. Therefore, the annual interest rate that you paid is 4.17%. Hope this answer helps.
Final answer:

The annual interest rate paid for the pawned guitar is calculated to be 640%, which is obtained by dividing the interest paid by the original loan amount to find the monthly rate and then multiplying by 12.

Explanation:

To calculate the annual interest rate paid for pawning the guitar, we need to first determine the total interest paid, then the monthly interest rate, and finally convert that to an annual rate. The interest paid is the difference between the amount received from pawning the guitar and the amount paid to redeem it, which is $1,472 - $960 = $512.

As the loan was for one month, we can determine the monthly interest rate by dividing the interest paid by the principal amount. This gives us $512 / $960 = 0.5333 or 53.33%. To find the annual interest rate, we multiply the monthly rate by 12 (the number of months in a year). Thus, the annual interest rate is 53.33% * 12 = 640%.

It's important to note that this is an extremely high rate of interest, which is not uncommon for pawnshop loans or other short-term high-risk loans.

I hope my solution has come to your help. Have a nice day ahead and may God bless you always!

Answer:

His gross pay would be reduced $174.66.

Step-by-step explanation:

Gross pay of Marquis = $816

His withholding are :

Federal tax = $92.00

Social security tax = 6.2% of $816

                               = 0.062 × 816

                               = $50.592

Medicare tax      = 1.45% × 816

                           = 0.0145 × 816

                           = $11.832

State tax            = 22% × 92

                          = 0.22 × 92

                         = $20.24

Total withholding = 92 + 50.59 + 11.83 + 20.24

                             = $174.66

His net pay = $816 - $174.66 = $641.34

His gross pay would be reduced $174.66

If ABCDE is a regular pentagon and diagonals EB and AC intersect at O, then what is the degree measure of angleEOC?

Answers

If ABCDE is a regular pentagon and diagonals EB and AC intersect at O, then the degree measure of angle EOC is 108°.

In Mathematics and Geometry, the sum of the interior angles of both a regular and irregular polygon is given by this formula:

Sum of interior angles = 180 × (n - 2)

Note: The given geometric figure (regular polygon) represents a pentagon and it has 5 sides.

Sum of interior angles = 180 × (5 - 2)

Sum of interior angles = 180 × 3

Sum of interior angles = 540°.

Therefore, the measure of each interior angle is given by;

Interior angle of a pentagon = 540°/5

Interior angle of a pentagon = 108°

From triangle EAO, we have:

2m∠EOA = 180° - (54 + 54)°

m∠EOA = 72°/2

m∠EOA = 34°

Now, we can determine the measure of angle EOC;

m∠EOC = 180° - (34 + 34)°

m∠EOC = 108°

Now its either B) or C) Lets examine the WRONG answer and then explain why the other is right

B) This answer cant be right because of a how liars work. If beside 2 liars, they HAVE to lie and say they are beside 2 truths. Since each person (in the claimed scenario) says they are besides 2 liars, then this cant happen.

C) Only option left, but ill explain anyway. Since there are 2 truths, they can both tell the truth will the liars always have at least 1 truth to the left or right of them to allow them to lie. (the inverse of D) with 3 truths)

Hope diagrams helped!

The answer is:  B. 1 - Only one of the five people is telling the truth.

In this scenario, we are given that five people are sitting around a circle. Some always tell the truth, while others always lie. Each person claims to be sitting between two liars.

Let's analyze the possibilities:

If all five people were telling the truth, each person's claim of sitting between two liars would be true. However, this would mean that all five people are telling the truth, which contradicts the given information.

If none of the five people were telling the truth, each person's claim of sitting between two liars would be false. However, this also contradicts the given information.

Given these two possibilities, we can conclude that there must be a combination of truth-tellers and liars among the five people.

Considering the options given:

A. 0: This suggests that none of the people are telling the truth. However, this contradicts the given information that some people always tell the truth.

B. 1: This suggests that only one person is telling the truth. In this case, this person's claim of sitting between two liars would be true, while the claims of the other four people would be false. This option aligns with the given information and is a valid possibility.

C. 2, D. 3, E. 4: These options suggest that multiple people are telling the truth. However, if more than one person tells the truth, their claims of sitting between two liars cannot all be true.

Based on the analysis, the answer is:

B. 1 - Only one of the five people is telling the truth.
