The answer of the question based on the to represent the area of the figure the answer is given below,
What is Rectangle?A rectangle is four-sided polygon with opposite sides that are parallel and congruent (equal) in the length.
a) The figure is a rectangle with a length of 2x + 3 and a width of x - 2. The area of the rectangle is:
Area = length x width
Area = (2x + 3)(x - 2)
Using the distributive property of multiplication, we can simplify this expression:
Area = 2x² - 4x + 3x - 6
Area = 2x² - x - 6
Therefore, the expression for the area of the figure is 2x² - x - 6.
The figure is a trapezoid with a height of 3 and two parallel sides of length x + y and x - y. average of lengths of the two sides are:
(x + y + x - y)/2 = 2x/2 = x
So, the area of the trapezoid is:
Area = (1/2) x height x (sum of parallel sides)
Area = (1/2)(x)(3)(x + y + x - y)/2
Area = (3/2) x²
Now, we need to subtract the area of the triangle from the trapezoid. The triangle has a height of 3 and a base of y, so its area is:
(1/2)(y)(3) = (3/2)y
Therefore, the expression for the area of the figure is:
Area = (3/2)x² - (3/2)y.

The payment (future value), to the nearest rand, which should be made at the end of the seventh year in order to liquidate the debt, is R9,338.80.
What is the future value determined?The future payment to be made at the end of the seventh year is determined by computing the future values in two stages. The first stage computes the future value before the payment at the end of the first year. The second stage computes the future value for six years.
here, we know,
The future value is computed by compounding the present value at an interest rate.
Current debt = R6,421,00
Compound interest rate = 11% per year
Compounding period = Quarterly
Future Value in 1 Year:
N (# of periods) = 4 quarters (1 year x 4)
I/Y (Interest per year) = 11%
PV (Present Value) = R6,421.00
PMT (Periodic Payment) = R0
Results:
Future Value (FV) = R7,156.98
Total Interest = R735.98

What is Expression ?
Mathematical statements called expressions must contain a minimum of two terms with either numbers, variables, or both, joined by an operator. The four different types of mathematical operators are addition, subtraction, multiplication, and division. For instance, the expression x + y is an expression where x and y are terms with an addition operator between them. Mathematical expressions can be divided into two categories: algebraic expressions, which include both numbers and variables, and numerical expressions, which solely contain numbers.
On first day, Jordan's football team gained 12 yards.
On second day, Jordan's football team lost 8 yards.
So, The total yards(net) would be :
= total yards gained by team - total yards lost by team
= 12 - 8

Question 7 Find the quotient and remainder using (x^(5)-x^(4)+9x^(3)-9x^(2)+9x-12)/(x-1) The quotient is
Answers
The quotient and remainder using (x^(5)-x^(4)+9x^(3)-9x^(2)+9x-12)/(x-1) are 1x^(4)-2x^(3)+11x^(2)-20x+29 and -41, respectively.
To find the quotient and remainder using (x^(5)-x^(4)+9x^(3)-9x^(2)+9x-12)/(x-1), we will use synthetic division.
Write down the coefficients of the dividend polynomial in descending order of the exponent of x. In this case, the coefficients are 1, -1, 9, -9, 9, -12.
Write down the constant term of the divisor polynomial. In this case, the constant term is -1.
Bring down the first coefficient of the dividend polynomial.
Multiply the constant term of the divisor polynomial by the first coefficient of the dividend polynomial and write the result under the second coefficient of the dividend polynomial.
Add the second coefficient of the dividend polynomial and the result from step 4.
Repeat steps 4 and 5 until all the coefficients of the dividend polynomial have been used.
The last result from step 5 is the remainder. The other results are the coefficients of the quotient polynomial.
The synthetic division is shown below:
-1 | 1 -1 9 -9 9 -12
| -1 2 -11 20 -29
---------------------
1 -2 11 -20 29 -41
The quotient is 1x^(4)-2x^(3)+11x^(2)-20x+29 and the remainder is -41.
Therefore, the quotient and remainder using (x^(5)-x^(4)+9x^(3)-9x^(2)+9x-12)/(x-1) are 1x^(4)-2x^(3)+11x^(2)-20x+29 and -41, respectively.

For the trapezoid given the value for x is obtained as 6.
What is a trapezoid?A polygon with only one set of parallel sides is called a trapezoid. The parallel bases of a trapezoid are another name for these parallel sides. Trapezoids have two additional sides that are not parallel and are referred to as their legs.
The value for parallel sides of a trapezoid is given as 3x + 2 and 2x - 2.
A line segment divides the trapezoid in half.
The line segment dividing the trapezoid in half measures 15 units.
We know that the line segment dividing the trapezoid in half is also the average of the parallel sides.
So we can set up an equation -
(3x + 2 + 2x - 2) / 2 = 15
Simplifying the left side, we get -
(5x) / 2 = 15
Multiplying both sides by 2/5, we get -
x = 6
Therefore, the value of x is 6.
We can check that this value works by plugging it into the expressions for the parallel sides -
3x + 2 = 20
2x - 2 = 10
So the lengths of the parallel sides are 20 and 10.
Therefore, the average of these is indeed 15, and so the line segment dividing the trapezoid in half has length 15, as given.

What is addition in mathematics?
Addition is one of the four basic arithmetic operations in mathematics, along with subtraction, multiplication, and division. Addition is the process of combining two or more quantities or numbers to find their sum, or total. The symbol used to represent addition is the plus sign (+).
For example, if we want to find the sum of 3 and 4, we would write:
3 + 4 = 7
The number 3 and the number 4 are called addends, and the result of the addition operation is called the sum. Addition can involve whole numbers, fractions, decimals, and even negative numbers.
Addition has many applications in mathematics, science, and everyday life. It is used to calculate simple arithmetic problems, such as adding up the cost of items in a shopping cart, as well as more complex calculations, such as adding up the values in a data set or solving equations in algebra.
To find the total number of hours Eric worked in the neighborhood garden, we need to add the number of hours he worked on Monday and Wednesday.
Eric worked 3 1/2 hours on Monday, which can also be written as 7/2 hours.
Eric worked 4 1/4 hours on Wednesday, which can also be written as 17/4 hours.
To add these two amounts, we need to find a common denominator. The smallest number that both 2 and 4 divide into is 4. So we can convert 7/2 to 14/4 by multiplying the numerator and denominator by 2:
7/2 = 14/4
Now we can add the two fractions:
14/4 + 17/4 = 31/4
This is the total number of hours Eric worked in the neighborhood garden, in fraction form. To write it as a mixed number, we can divide the numerator by the denominator:
31 ÷ 4 = 7 with a remainder of 3
So the total number of hours Eric worked is 7 3/4 hours.

3. You randomly selected 36 LCD compute monitors. What is the probability that their mean cost is less than $ 180?
Answers
1. The probability of getting a z-score of 0.189 or less is 0.5753.
2. The probability of getting a z-score of 1.13 or less is 0.8708.
3. The probability of getting a z-score of 3.02 or less is 0.9982.
What is Normally distributed data:Normally distributed data refers to data that follows a normal distribution, also known as a Gaussian distribution or bell curve.
In a normal distribution, the data is symmetric around the mean and the majority of the data is clustered around the mean with decreasing density as the data moves further away from the mean.
Here we have
The mean price for liquid crystal display (LCD) computer monitors is $ 170 and the standard deviation is $ 53.
Find the z-score associated with $ 180 using the formula:
z = (x - μ) / σ
where x is the value we need to find the probability, μ is the mean, and σ is the standard deviation.
z = (180 - 170) / 53
z = 0.189
Hence, using a standard normal distribution table or calculator, we can find that the probability of getting a z-score of 0.189 or less is 0.5753.
To find the probability that the mean cost of 9 randomly selected LCD computer monitors is less than $ 180, find the standard deviation σ/√n.
The standard deviation of the sample means is σ/√n = $53/√9 = $17.67.
Now we need to find the z-score associated with $ 180 using the formula:
z = (x - μ) / σ/√n
where x is the sample mean, μ is the population mean, σ is the population standard deviation, and n is the sample size.
z = (180 - 170) / (53 / √9)
z = 1.13
Hence, using a standard normal distribution table or calculator, we can find that the probability of getting a z-score of 1.13 or less is 0.8708.
To find the probability that the mean cost of 36 randomly selected LCD computer monitors is less than $ 180, we can use the same formula as in part 2, with n = 36:
z = (x - μ) / σ/√n
z = (180 - 170) / (53 / √36)
z = 3.02
Hence, using a standard normal distribution table or calculator, we can find that the probability of getting a z-score of 3.02 or less is 0.9982.
Therefore,
1. The probability of getting a z-score of 0.189 or less is 0.5753.
2. The probability of getting a z-score of 1.13 or less is 0.8708.
3. The probability of getting a z-score of 3.02 or less is 0.9982.

where 0 ≤ t ≤ 10.
a) how much oil is in the tank initially?
b) determine the average rate of change of volume in the first 1 minutes.
c) estimate the instantaneous rate of change of volume at 5 minutes. Do NOT use Calculus.
Answers
a) Initially, when t = 0, the volume of oil in the tank is given by:
V(0) = 0.5(10 - 0)^3
V(0) = 0.5(1000)
V(0) = 500
So, initially there are 500 litres of oil in the tank.
b) The average rate of change of volume in the first 1 minute is given by:
ΔV/Δt = (V(1) - V(0))/(1 - 0)
ΔV/Δt = (0.5(10 - 1)^3 - 500)/1
ΔV/Δt = (0.5(729) - 500)/1
ΔV/Δt = -285.5
So, the average rate of change of volume in the first 1 minute is -285.5 litres/minute.
c) To estimate the instantaneous rate of change of volume at 5 minutes, we can use the average rate of change over a small interval around 5 minutes. For example, we can use the average rate of change from 4.9 minutes to 5.1 minutes:
ΔV/Δt = (V(5.1) - V(4.9))/(5.1 - 4.9)
ΔV/Δt = (0.5(10 - 5.1)^3 - 0.5(10 - 4.9)^3)/0.2
ΔV/Δt = (-61.4455 - (-62.985))/0.2
ΔV/Δt = 7.6975
So, the estimated instantaneous rate of change of volume at 5 minutes is 7.6975 litres/minute.

Answers
Renee's monthly payment will be $504.46. The closest answer choice is d. $504.46.
How did we arrive at this value?To calculate Renee's monthly payment, we need to first determine the total cost of the new car after taxes and fees and subtract the trade-in value of her old car. Then, we can use the loan information to calculate the monthly payment.
Total cost of the new car:
List price: $19,675
Vehicle registration fees: $1,420
Documentation fees: $85
Sales tax: 8.92% of ($19,675 + $1,420 + $85) = $1,894.51
Total cost = $19,675 + $1,420 + $85 + $1,894.51 = $22,074.51
Trade-in value of the old car:
2002 Buick LeSabre in good condition: $3,374 (from the table)
85% of trade-in value: 0.85 x $3,374 = $2,867.90
Net cost of the new car:
$22,074.51 - $2,867.90 = $19,206.61
To calculate the monthly payment, we can use the formula for the present value of an annuity:
PV = PMT x (1 - (1 + r)^(-n)) / r
where PV is the present value of the loan, PMT is the monthly payment, r is the monthly interest rate (11.34%/12), and n is the number of payments (4 years x 12 months/year = 48).
Solving for PMT:
PMT = PV x r / (1 - (1 + r)^(-n))
PMT = $19,206.61 x 0.1134/12 / (1 - (1 + 0.1134/12)^(-48))
PMT = $504.46
Therefore, Renee's monthly payment will be $504.46. The closest answer choice is d. $504.46.

An online keyboarding course collects data comparing each students age to their typing speed. The equation of the line of best fit representing this data is y=-1.4x+117.8 , where x is the age (years) and y is the typing speed (words per minute). What is the expected typing speed of a student who is 17 years old?
Answers
Therefore, the expected typing speed of a student who is 17 years old is 94 words per minute.
What does speed feel like?It functions by dividing distance by speed. The time can also be calculated by dividing the distance traveled by the speed. You can determine the third input if you know the first two. For instance, we may get the speed as 120 x 2 = 60 miles per hour if a car travels 120 miles in two hours.
The equation of the line of best fit is:
y = -1.4x + 117.8
where x is the age in years and y is the typing speed in words per minute. To find the expected typing speed of a 17-year-old student, we can substitute x = 17 into the equation:
y = -1.4(17) + 117.8
y = -23.8 + 117.8
y = 94
Therefore, the expected typing speed of a student who is 17 years old is 94 words per minute.

The average number of gallons W of bottled water consumed each year by the consumer can be approximated by W=1.8d+17.48, where d is the number of 2000.
Answers
The average number of gallons of bottled water consumed in the year 2010 is 35.48 gallons.
The equation W=1.8d+17.48 can be used to find the average number of gallons of bottled water consumed each year by a consumer.
In this equation, W represents the average number of gallons of bottled water consumed, and d represents the number of years since 2000.
To find the average number of gallons of bottled water consumed in a specific year, you can plug in the value of d into the equation and solve for W.
For example, if you want to find the average number of gallons of bottled water consumed in the year 2010, you would plug in the value of d=10 (since 2010 is 10 years after 2000) into the equation:
W=1.8(10)+17.48
W=18+17.48
W=35.48
So, the average number of gallons of bottled water consumed in the year 2010 is 35.48 gallons.
Similarly, you can plug in different values of d into the equation to find the average number of gallons of bottled water consumed in different years.
