what is the remainder when you divide 2x^3+4x^2 - x +3 by x+2
Answer: The required remainder is 5.
Step-by-step explanation: We are given to find the remainder when we divide the following cubic polynomial by (x+2 :
3 f(x)=2x^ 3 +4x^ 2 - 6^ 2 -x+
(i)
We have the following theorem:
Remainder theorem: If a polynomial p(x) is divided by the factor (x-a), then the remainder is p(a).
So, for the given linear factor, we have
x + 2 = 0
Rightarrow x=-2
Substituting x = - 2 in equation (i), we get
f(- 2)
=2(-2)^ 3 +4(-2)^ 2 -(-2)+3
=-16+16+2+3
=5 .
Thus, the required remainder is 5.

Consider the following quadratic equation.
(x + 3)2 = 43
When taking the square root of both sides of this equation, how many solutions will the equation
have? How do you know?
Answer choices ⬇️
Answer:
(x+3)
2
=43
BY TAKING SQUARE ROOT ON BOTH SIDES
x + 3 = \sqrt{43}x+3=
43
OR
x + 3 = - \sqrt{43}x+3=−
43
THUS
x = \sqrt{43} - 3x=
43
−3
OR
x = - \sqrt{43} - 3x=−
43
−3
THIS QUADRATIC EQUATION HAS 2 SOLUTIONS SINCE √43 CAN BE A POSITIVE OR A NEGATIVE INTEGER. FOR EXAMPLE, 2^2=4
BUT, (-2)^2=4 Thus. √4=2 or (-2)
After this. Simply shifting the 3 on the LHS to keep 'x' on one side to find its value.
Taking the square root of both sides of the equation (x + 3)² = 43 will result in two solutions for x.
The correct option is C.
What is a quadratic equation?A basic quadratic equation, or a second-order polynomial equation with a single variable, is represented by the equation x : ax² + bx + c = 0, where a≠0 for the variable x. As it is a second-order polynomial equation, which is ensured by the algebraic fundamental theorem, it must have at least one solution.
When taking the square root of both sides of the equation (x + 3)² = 43, we get:
x + 3 = ±√43
To solve for x, we can subtract 3 from both sides:
x = -3 ±√43
So there are two solutions for x:
x = -3 + √43
x = -3 - √43
Therefore, the solutions are x = -3 + √43 and x = -3 - √43.

What is insurance?Insurance is a means of protection from financial loss in which, in exchange for a fee, a party agrees to compensate another party in the event of a certain loss, damage, or injury. It is a form of risk management, primarily used to hedge against the risk of a contingent or uncertain loss.

We have,
To calculate Sheila annual property insurance premium, we need to determine the appropriate rating based on the type of house and the area where it is located. Aida's house is a brick house in the country,
So we need to use the "Brick" and "Rural" ratings from the table.
The rating for the building is 0.6 per $100 of coverage, so for a value of $95,000, the premium for the building is:
0.6 x $950 = $570
The rating for the contents is 0.69 per $100 of coverage, so for a value of $15,000, the premium for the contents is:
0.69 x $150 = $103.50
The total annual premium is:
$570 + $103.50 = $673.50
Thus,
Her annual property insurance premium is $673.50.

Answer:
C. No solution.
Step-by-step explanation:
Due to the y-intercepts (When the equation is in slope-intercept form: 1.5, and 3.5) we can identify that the equations are parallel from each other.
The slopes are the same, but the y-intercepts are different, the equations will be 2 (y) apart since each will intersect at different values. This means that both equations can't intersect with each other, making it impossible to find a solution.

(i) Find the factors of the given polynomial.
(ii) if she purchase 5kg papaya, what money she have to pay?
Answer:
p ( x ) = ( x- 6 ) ² - 256
Step-by-step explanation:
1- Add the same value to both sides
2- Add 36 to the expression
3- Add 36 to the left-hand side
4- Factor the expression
5- Move the constant to the right
6- Calculate
The factors of the given polynomial is (x-10) (x+22) and the price of 5 kg papaya is 5x²-60x-1100.
What is Polynomial?An algebraic expression known as a polynomial requires that all of its exponents be whole numbers. Any polynomial must have variable exponents that are non-negative integers. Although a polynomial contains variables and constants, we are unable to divide a polynomial by a variable.
Given:
p(x) = x² – 12x – 220
i) These two terms are 22x and -11x.
p(x) = x²-12x-220
p(x) = x²+22x-10x-220
Taking x common from the first two terms and -10 from the last two terms,
x(x+22)-10(x+22)
(x-10) (x+22)
ii) We are given that the rate of papaya per kg is p(x) = x²-12x-220.
1 kg = x²-12x-220
5 kg = 5(x²-12x-220)
5 kg = 5x²-60x-1100

What is an inequality?An inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions. It is used most often to compare two numbers on the number line by their size.
Given is an expression, we need to determine the all values of x for which the product is defined,
The product is √4x · √x+2
We must meet both conditions:
(4x) ≥ 0 and (x+2) ≥ 0
So, 4x ≥ 0
x ≥ 0
And, x ≥ -2 [subtract 2 from both sides.]
So, we can say the condition should be x ≥ 0
Hence, the inequality that represents all values of x for which the product is defined is x ≥ 0

In a bag, there are a total of 50 dimes and quarters. 40% of the coins are quarters and 35% of the quarters are on heads. How many of the quarters are on tails?
Answer:
13 quarters must be tails.
Step-by-step explanation:
Number of quarters = 40% of 50 coins
Number of quarters = 40/100 * 50 = 20 coins which are quarters.
35% of these 20 quarters on heads. We can proceed in 2 ways from here.
We can actually find the number of quarters that are on heads.
35/100 * 20 = 7 quarters are showing heads.
Since the other quarters must be tails 20 - 7 = 13 quarters must be tails.
The other way to do it is to realize that if 35% of the coins are heads, 65% of the coins must be tails 20 * 65/100 = 13 which is a bit more direct.

Cost equation is y=X+2000, where X is the number of tubes of toothpaste manufactured and y is the cost of producing X tubes. The following set of axis shows the graph of the cost and revenue equations. For what X-values will the company make a profit”
The company will make a profit for X-values: (greater than, less than, or equal to) ____?
Answer:
The revenue equation is y=2.6x,
cost equation is y=x+2000
When the company makes profit only when revenue > cost
Lets frame inequality using revenue > cost
Replace the revenue equation and cost equation
Now solve the inequality for x
Subtract 1x from both sides
Divide both sides by 1.6
The company makes profit when x is greater than 1250
Step-by-step explanation:
Answer:
Greater than 1250
x > 1250
Step-by-step explanation:
Base on the revenue equation and cost equation , we can infer that the company make a profit when x > 1250
Important Given Information:
The revenue equation is [tex]y=2.6x[/tex]
Cost equation is [tex]y = x+2000[/tex]
When the company makes profit only when: [tex]revenue > cost[/tex]
Let's frame inequality using: [tex]revenue > cost[/tex]
Replace the revenue equation and cost equation
[tex]Revenue > Cost: 2.6x > + 2000[/tex]
Now Let's solve the inequality for x
[tex]2.6x > 1x + 2000[/tex]
[tex]2.6x - 1x > 2000[/tex] [tex][2.6x-1x=1.6x][/tex]
[tex]1.6x > 2000[/tex]
Divide both sides by 1.6 ( what you do on one side do to the other)

Devon is making table runners for his niece's wedding. The short tables are 6 feet
(ft) long, and the long tables are 10 ft long. Each runner will overhang its table by 8
inches (in.) on each end. Devon was told there will be 12 small tables and twice that
number of long tables. How many total yards (yd) of fabric will he need to make the
table runners, assuming no waste? (Note: 12 in. = 1 ft and 3 ft = 1 yd.)
The sum of the lengths of the tables and the total length of overhang
give the length of fabric that Devon needs.
Response:
The total yards of fabric needed to make the table runners is 12 yd.How can the given dimensions be added to obtain the length of fabric needed?The given parameters are;
Length of the small tables = 6 feet
Length of the long tables = 10 feet
Length of overhang on each end = 8 inches
Number of small tables = 12
Number of long tables = 2 × 12 = 24
Required:
The yards of fabric needed to make the table runners.
Solution;
The total number of tables = 12 + 24 = 36
Length of overhang for each table = 8 inches + 8 inches = 16 inches
Sum of the length of the overhang = 36 × 16 inches = 576 inches
From the given unit conversion factors, we have;
Sum of the length of overhang = 576 inches ÷ 12 inch/feet = 48 feet
Length of the tables = 12 × 6 feet + 24 × 10 feet = 312 feet
Total length of table runner = 312 feet + 48 feet = 360 feet
Length of table runner needed = 360 feet ÷ 3 feet/yd = 120 yd.
