Show that x+2 is a factor of f(x)=x^4+2x^3−27x−54 . Then factor f(x) completely.
f(x)=
Answer:
Step-by-step explanation:
The polynomial f(x)=x^4+2x^3−27x−54 has x+2 as a factor. The complete factorization of f(x) after polynomial division and analysis is (x + 2)(x^2 - 3x + 9)(x + 3).
Explanation:To show that x+2 is a factor of f(x)=x^4+2x^3−27x−54, we need to use the Factor theorem which states that if a polynomial f(x) has a factor of the form x - k, then f(k) = 0.
So, if x + 2 is a factor of the function, then f(-2) should equal 0. Let's apply this to our function:
f(-2) = (-2)^4 + 2(-2)^3 - 27(-2) -54 = 16 -16+54 -54 = 0. So x+2 is indeed a factor.
To factor f(x) completely, we will perform polynomial division of f(x) by the factor (x+2) which will give us g(x) = x^3 - 27. This can be further factored to x^3 - 3^3 which is a difference of cubes. Consequently, the complete factorization of f(x) would be:
f(x) = (x + 2)(x^2 - 3x + 9)(x + 3).

if everything costs $25.30 and there is an 8% meals tax, how much does the meal cost ?
Answer:
Total cost of the meal is $ 27.32.
Step-by-step explanation:
Given:
Cost of the meal = $25.30
Tax levied on it = 8%
We have to find the total cost.
Total cost of the meal = Summation of cost of the meal and levied tax.
So,
We have to calculate the tax.
⇒ [tex]8\%\ of\ \$25.30[/tex]
⇒ [tex]\frac{8}{100}\times \$25.30[/tex]
⇒ [tex]0.08\times \$25.30[/tex]
⇒ [tex]\$2.024[/tex]
Tax imposed = [tex]\$2.024[/tex]
Now,
Total cost of the meal =Tax + Meal cost
⇒ [tex]\$(2.024+25.30)[/tex]
⇒ [tex]\$27.324[/tex]
Total cost of the meal is $ 27.32.

Sarah sold a total of 178 t shirts and posters at a festival. She sold 46 more tshirts than poster. How many posters did she sell
Sarah sold 66 posters
Solution:
Let "a" be the number of shirts sold
Let "b" be the number of posters sold
Sarah sold a total of 178 t shirts and posters at a festival
Therefore,
number of shirts sold + number of posters sold = 178
a + b = 178 ----------- eqn 1
She sold 46 more tshirts than poster
Number of shirts sold = 46 + number of posters sold
a = 46 + b --------- eqn 2
Substitute eqn 2 in eqn 1
46 + b + b = 178
2b = 178 - 46
2b = 132
b = 66
Thus she sold 66 posters
Final answer:
Sarah sold 66 posters at the festival.
Explanation:
Let's represent the number of posters Sarah sold as P. Since she sold 46 more t-shirts than posters, we can represent the number of t-shirts as P + 46. The total number of t-shirts and posters sold is 178, so we can write the equation: P + (P + 46) = 178.
Combining like terms, we get: 2P + 46 = 178. Subtracting 46 from both sides, we have: 2P = 132. Dividing both sides by 2, we find: P = 66.
Therefore, Sarah sold 66 posters at the festival.
If a rectangle has an area of 2x^2+7x+3 find the perimeter
Perimeter of a rectangle = 6x + 8
Solution:
Given area of a rectangle = [tex]2x^2+7x+3[/tex]
Let us first factor the given polynomial.
[tex]2x^2+7x+3=2x^2+x+6x+3[/tex]
[tex]=(2x^2+x)+(6x+3)[/tex]
Taking out common terms in the above expression
[tex]=x(2x+1)+3(2x+1)[/tex]
Taking out common term [tex]2x+1[/tex] in the above expression
[tex]=(2x+1)(x+3)[/tex]
[tex]2x^2+7x+3=(2x+1)(x+3)[/tex]
Area of a rectangle = l × b
Therefore, [tex]l=2x+1[/tex] and [tex]b=x+3[/tex]
Perimeter of a rectangle = 2(l + b)
[tex]=2[(2x+1)+(x+3)][/tex]
[tex]=2(2x+1+x+3)[/tex]
[tex]=2(3x+4)[/tex]
[tex]=6x+8[/tex]
The answer is same if you take l = x + 3 and b = 2x + 1.
Hence, perimeter of a rectangle = 6x + 8.

The variable y is directly proportional to the variable x. If y = 32 when x = 20, what is the value of x when y = 40?
A)
20
B)
20.5
C)
25
D)
30
Answer:
The Correct option is C ) 25
Therefore the value of x is 25 when y =40.
Step-by-step explanation:
Given:
Variable 'y' is directly proportional to the variable 'x'.
[tex]\therefore y=kx[/tex] ......Direct Variation
Where,
k = Constant of proportionality
To Find:
value of x = ? when y = 40
Solution:
First we need to find Constant of proportionality
When x = 20 and y = 32
Substituting the values we get
[tex]32=k\times 20\\k=\dfrac{32}{20}=1.6\\\\k=1.6[/tex]
Now when k =1.6 , y = 40 then x will be
[tex]40=1.6\times x\\\\x=\dfrac{40}{1.6}=25\\\\x=25[/tex]
Therefore the value of x is 25 when y =40.
Final answer:
The value of x when y is 40 is C) 25.
Explanation:
The variable y is directly proportional to the variable x.
This means that as x increases or decreases, y does so at a constant rate.
This relationship can be written as y = kx, where k is the constant of proportionality.
To find k, we use the information that y = 32 when x = 20, leading to the equation 32 = k * 20.
Solving this gives us k = 32 / 20 or k = 1.6.
With the constant k known, we can find the value of x when y = 40 by setting up the equation 40 = 1.6x.
Dividing both sides by 1.6 gives us x = 40 / 1.6, which results in x = 25.
Therefore, the correct answer is C) 25.

Evaluate the expression 1/3 (4+18) 4
Answer:
29 1/3
Step-by-step explanation:
1/3 (4 + 18) 4
1/3 (22) 4
7 1/3 x 4
29 1/3
Twenty nine and one third is your answer.
Final answer:
The expression 1/3 (4+18) 4 evaluates to approximately 29.333 following the order of operations; first the addition inside the parentheses, then multiplication by 1/3, and lastly by 4.
Explanation:
When evaluating the expression 1/3 (4+18) 4, it's essential to follow the orders of operation, often remembered by the acronym PEMDAS (Parentheses, Exponents, Multiplication, and Division (from left to right), Addition and Subtraction (from left to right)). Let's break down the problem step by step:
First, handle the operations inside the parentheses: 4 + 18 = 22.Multiply by the fraction outside, which is 1/3 of 22: (1/3) * 22 = 22/3.Finally, multiply by the last number, which is 4: (22/3) * 4.Now, perform the multiplication: 22 * 4 = 88. Since we are multiplying by a division by 3 (22/3), it is the same as dividing 88 by 3, which gives us the final answer: 88 divided by 3 equals 29 with a remainder of 1, or as a decimal, approximately 29.333.
The correct answer to the expression 1/3 (4+18) 4 is therefore approximately 29.333. It is crucial to always follow the order of operations in any math problem to get the correct result.

what is the side of equilateral triangle is altitude is 10
Answer:
11.55
Step-by-step explanation:
An equilateral triangle is one which all it sides are equal.
10cm altitude means the height is 10cm.
Using Pythagoras theorem,
x² = 10² + (x/2)²
Assume that the side of the triangle is xcm
x² - x²/4 = 100
3x²/4 = 100
x = √(400/3)
x = 11.55cm

What can 8/6 be simplified to
Answer: 4/3
Explanation: To write the fraction 8/6 in lowest terms, we divide the numerator and the denominator by the greatest common factor of 8 and 6.
Since the factor of 8 are 1, 2, 4, and 8 and the factors of 6 are 1, 2, 3, and 6, the greatest common factor of 8 and 6 is 3 so we divide the numerator and the denominator of 8/6 by 2 and we get 4/3.
So 8/6 can be simplified to 4/3.
4/3 can also be changed to the mixed number 1 and 1/3.

Answer:
A) -2/3
Step-by-step explanation:
We are given the equation;
5 - 2m - 3m² = 0
We are required to get the sum of the roots of the equation;
We will solve the equation to get the two roots,Using factor method;Rearranging the equation;
3m² + 2m - 5 = 0
product = -15 m²
sum = 2 m
Terms = 5m and -3m
Therefore;
3m² + 5m - 3m - 5 = 0
Factorizing by pairing
m(3m + 5) - 1 (3m + 5) = 0
Thus;
(m - 1) (3m + 5) = 0
This means;
m - 1 = 0 or 3m + 5 =0
Hence; the roots of the equation are;
m = 1 or m = -5/3
Thus, the sum of the roots is;
= 1 + -5/3
= -2/3
Hence, the sum of the roots of the equation is -2/3

Answer:
90°
Step-by-step explanation:
All circles are equal to 360°. Since the pie chart is a circle, if you added all of the central angles for all three sections, it would total to 360°.
Since the circle is not divided into 360 parts for each degree, but 100 parts for each percent %.
You can solve using an equivalent. Write each fraction in the form "Lemonade" over "total". The left side is percentage, the right side is degrees.
Let x be the central angle for lemonade
[tex]\frac{25}{100}=\frac{x}{360}[/tex]
Solve for the central angle of lemonade by isolating 'x'. To isolate x, move 360 over to the other side. When moving numbers in an equivalent, you do the opposite operation to both sides. Since 'x' divides by 360, multiply 360 on both sides.
[tex]\frac{25}{100}=\frac{x}{360}[/tex]
[tex]360*\frac{25}{100}=360*\frac{x}{360}[/tex] 360 cancels out on the right
[tex]\frac{360*25}{100}=x[/tex] Combined multiplication in numerator
[tex]\frac{9000}{100}=x[/tex] When dividing, 0s cancel out
[tex]\frac{90}{1}=x[/tex] Simplify fraction over 1
[tex]x = 90[/tex] Answer
Therefore the central angle in the Lemonade section is 90°.
X^2 + Y^2 +4y =3 complete the square on the x and y terms to find the radius and center of a circle
Answer:
Center = (0, -4)
Radius = [tex]\sqrt{7}[/tex] units
Step-by-step explanation:
We are given;
The equation of a circle;
[tex]x^2+y^2+4y=3[/tex]
We are required to determine the radius and the center of the circle;
To do this we are going to use completing square method;
[tex]x^2+y^2+4y=3[/tex]
Since we don't have the x term then;
[tex]x^2+ox+y^2+4y=3[/tex]
We add the square of half the coefficients of x and y on both sides of the equation;
That is;
[tex]x^2+0x+(0^2)+y^2+4y + (2^2)=3+0+(2^2)[/tex]
We get;
[tex]x^2+0x+(0^2)+y^2+4y + (2^2)=7[/tex]
Taking the squares;
[tex](x+0)^2+(y+4)^2=7[/tex]
But we know when the equation of a circle is written in the form of;
[tex](x-a)^2+(y-b)^2=r^2[/tex], where (a,b) is the center and r is the radius of the circle.
Thus, in this case;
[tex](x+0)^2+(y+4)^2=7[/tex]
Center = (0, -4)
Radius = [tex]\sqrt{7}[/tex] units
