Simplifying the expression (2x³ – 2x² – 40x )/(2x² + 5x - 12) ÷ (6x⁴ – 150x²)/(8x³ - 27) will result to (x - 5)/(3x(x - 3)(x + 5)).
To simplify the given expression completely, we need to factor the numerator and denominator of each fraction, and then simplify by canceling out common factors.
(2x³ – 2x² – 40x )/(2x² + 5x - 12) ÷ (6x⁴ – 150x²)/(8x³ - 27)
= (2x(x² - x - 20))/(2x^2 + 5x - 12) ÷ (6x^2(x^2 - 25))/(8x^3 - 27)
= (2x(x - 5)(x + 4))/(2x² + 8x - 3x - 12) ÷ (6x²(x - 5)(x + 5))/(8x³ - 27)
= (2x(x - 5)(x + 4))/(2x(x + 4)(x - 3)) ÷ (6x²(x - 5)(x + 5))/(8x³ - 27)
= (2x(x - 5)(x + 4))/(2x(x + 4)(x - 3)) × (8x³ - 27)/(6x²(x - 5)(x + 5))
= (x - 5)/(x - 3) × (8x³ - 27)/(6x²(x - 5)(x + 5))
= (x - 5)/(x - 3) × (2x - 3)(4x² + 6x + 9)/(6x²(x - 5)(x + 5))
= (x - 5)/(x - 3) × (2x - 3)/(6x(x - 5)(x + 5))
= (x - 5)/(3x(x - 3)(x + 5))
Therefore, the simplified expression is (x - 5)/(3x(x - 3)(x + 5)).

1. Calculate the compound interest on N2,000 for 2years at the rate of 10% per annum
The compound interest on N2,000 for 2 years at the rate of 10% per annum is N441.00.
Compound interest is the interest earned not only on the principal amount but also on the accumulated interest. To calculate the compound interest, we use the formula:
A = P[tex](1 + r/n)^{(nt)[/tex]where A is the final amount, P is the principal amount, r is the annual interest rate, n is the number of times interest is compounded per year, and t is the time in years.
In this case, P = N2,000, r = 0.1 (10%), n = 1 (compounded annually), and t = 2 years.
So, A = 2000[tex](1 + 0.1/1)^{(1*2)[/tex] = N2,441.00
Therefore, the compound interest is N2,441.00 - N2,000.00 = N441.00.

At an art fair, an artist recorded sales of 52 candles of two different sizes and a total of $269 collected. The smaller candle sells for $4 and the larger candle sells for $7.
A. Based on the artist’s records, how many of each size of candle were sold?
B. Is your answer reasonable? What might this imply about the artist’s records?
The artist sold 32 smaller candles and 20 larger candles.
What is equations ?An equation is a mathematical statement that shows the equality of two expressions. It contains an equals sign (=) and at least one variable. An equation can be true or false depending on the values of the variables. Solving an equation involves finding the value or values of the variable that make the equation true. Equations are used to model relationships between different quantities in a wide range of fields, including mathematics, physics, chemistry, economics, and engineering.
According to the given information :A. Let's represent the number of smaller candles sold as x and the number of larger candles sold as y. We know that x + y = 52 (since a total of 52 candles were sold) and 4x + 7y = 269 (since the total sales was $269 and smaller candles sell for $4 and larger candles sell for $7). We can use these two equations to solve for x and y.
Multiplying the first equation by 4, we get 4x + 4y = 208. Subtracting this from the second equation, we get:
4x + 7y - (4x + 4y) = 269 - 208
3y = 61
y = 20.33
This means that the artist sold 20.33 larger candles. However, since we cannot sell a fractional part of a candle, we need to round this down to 20. Similarly, we can find x by subtracting y from 52:
x = 52 - y = 52 - 20 = 32
So the artist sold 32 smaller candles and 20 larger candles.
B. The answer is reasonable since the number of smaller candles sold is larger than the number of larger candles sold, and the total sales amount is closer to the price of the smaller candle than the larger candle. This implies that the artist's records are likely accurate.
Therefore, the artist sold 32 smaller candles and 20 larger candles.

All four methods of "thinking out computation" provided in the question are correct and valid.
Method (a) is using the "doubles" method, which is a common mental arithmetic technique. By recognizing that 7+7 is 14, it is easy to add 1 more to get 15.
Method (b) is using the "subtracting by tens" method. By recognizing that 38 minus 10 is 28, it is easy to subtract 7 more to get 21.
Method (c) is using the distributive property of multiplication. By recognizing that 999 is very close to 1000, we can multiply 3 by 1000 and then subtract 3 to get 2997.
Method (d) is using the inverse operation of multiplication. By recognizing that 150 is a multiple of 3, we can think of 150 as 3 times some unknown number, and then determine that number by dividing 150 by 3. The answer is 50, which is the same as thinking of what equals 150 times 3 (450).

THURSDAY: Use Synthetic Division to divide the polynomial: (x^(4)-5x^(3)+4x-17)-:(x-5)
Synthetic Division of the polynomials (x^(4)-5x^(3)+4x-17) and (x-5) gives answer "x^(3)+4+3/(x-5)."
To divide the given polynomial using synthetic division, we will use the following steps:
Step 1: Write the coefficients of the polynomial in descending order. In this case, the coefficients are 1, -5, 0, 4, -17.
Step 2: Write the value of x from the divisor (x-5) in the left column. In this case, the value of x is 5.
Step 3: Bring down the first coefficient to the bottom row.
Step 4: Multiply the value of x by the number in the bottom row and write the result in the next column.
Step 5: Add the numbers in the second column and write the result in the bottom row.
Step 6: Repeat steps 4 and 5 until you have completed all the columns.
Step 7: The numbers in the bottom row are the coefficients of the quotient, and the last number is the remainder.
The synthetic division will look like this:
5 | 1 -5 0 4 -17
| 5 0 0 20
----------------
1 0 0 4 3
So, the quotient is x^(3)+0x^(2)+0x+4, or simply x^(3)+4, and the remainder is 3.
Therefore, the answer is (x^(4)-5x^(3)+4x-17)÷(x-5) = x^(3)+4+3/(x-5).

The cash register can be off by a maximum of $15
If the cash register can be off by a maximum of $15, it means that there is an acceptable range of error in the register's calculations. This could be due to various factors such as human error, technical malfunctions, or other issues.
How to explain the cash registerFor example, if a customer gives $50 for a purchase and the cash register calculates the total as $45, then the register is short by $5. If the register calculates the total as $65, then it is over by $15. As long as the error falls within the acceptable range of $15, it would not be considered a serious issue.
However, if the error is outside of this range, it may indicate a problem with the register that needs to be addressed. Inaccurate calculations can lead to financial losses for a business, so it is important to ensure that the cash register is functioning correctly and that any errors are promptly corrected.

The IikeIihood that the hawk wiII first take a songbird and subsequentIy a rabbit is therefore (2/9) x (8/11) = 16/99, or roughIy 0.1616.
Percent : Is there a second meaning?In mathematics, a percentage is a number or ratio that may be stated as a fraction of 100. Divide a number by the whole and multiply the result by 100 to calculate its percentage. As a result, the percentage represents a part per hundred. 100% is meant by the phrase %. The symbol "%" is used to indicate it.
The probability that a hawk will eat a songbird before a rabbit is calculated as the product of those probabilities.
Given that there are four songbirds with eight rabbits, the IikeIihood that a songbird wiII be consumed by a hawk is 4/(4+6+8) = 4/18 = 2/9.
Three songbirds & eight rabbits remain after the hawk consumes a songbird, hence the IikeIihood that the hawk wiII eat a rabbit next is 8/(3+8) = 8/11.

Sally collected 34.9 pounds of cans to recycle and plans to collect 3.3 more pounds each week. Write an equation in slope-intercept form where x represents the number of weeks Sally has been recycling cans, and y represents the total amount recycled.
Answer:
y = 3.3x + 34.9
Step-by-step explanation:
the slope-intercept form is y = mx + b.
y = total pounds of cans accumulated
m (slope) = pounds of cans collected each week (3.3)
x = # of weeks after sally starts collecting
b (y-intercept) = initial pounds of cans collected (34.9)
so:
y = (pounds per week)(# of weeks) + initial weight
y = 3.3x + 34.9
Find the period and amplitude. \[ y=-4 \sin \left(\frac{\pi x}{5}\right) \] period amplitude Need Help?
The period of the function is 10 and the amplitude is 4.
The period and amplitude of the function \[ y=-4 \sin \left(\frac{\pi x}{5}\right) \] can be found by examining the coefficients in the equation.
The amplitude is the absolute value of the coefficient in front of the sine function, which in this case is |-4| = 4. Therefore, the amplitude of the function is 4.
The period is found by dividing 2π by the coefficient in front of the x variable inside the sine function. In this case, the coefficient is \[\frac{\pi}{5}\]. So, the period is \[\frac{2\pi}{\frac{\pi}{5}} = 10\].
Therefore, the period of the function is 10 and the amplitude is 4.

plications Involving Factoring Polynomials Set up an algebraic equation and then solve. The width of a rectangle is 17 units less than the length. If the area is 60 square units, then find the dimensions of the rectangle. Length: units Width: units
The dimensions of the rectangle are: length: 20 units and width: 3 units.
To solve the problem, we can set up an algebraic equation using the formula for the area of a rectangle, which is A = length × width.
Let x be the length of the rectangle, and x - 17 be the width.
Then we can set up the equation:
60 = x(x - 17)
Simplifying the equation gives us:
x² - 17x - 60 = 0
Now we can factor the equation:
(x - 20)(x + 3) = 0
This gives us two possible solutions for x:
x = 20 or x = -3
However, since the length of a rectangle cannot be negative, we can disregard the second solution.
Therefore, the length of the rectangle is 20 units, and the width is 20 - 17 = 3 units.

What is the equation of the line that passes through the point ( − 4 , − 3 ) and has a slope of − 43?
Answer:
y = -43x - 175
Step-by-step explanation:
Slope-intercept form is y = mx + b
m = -43
x = -4
y = -3
-3 = -43(-4) + b
b + 172 = -3
b = -3 - 172 = -175
=> y = -43x - 175

Calculate the simple interest due on a 67-day loan of $2600 if
the interest rate is 5%. (Round your answer to the nearest
cent.)
The simple interest due on a 67-day loan of $2600 at a rate of 5% is $23.86.
To calculate this, we can use the following formula: I = Prt, where I is the interest due, P is the principal (or initial loan amount), r is the interest rate, and t is the time in years. We can calculate the time in years by taking the number of days (67) divided by the number of days in a year (365). Therefore, t = 0.1831. We can now plug this into our formula to get I = 2600 * 0.05 * 0.1831, which simplifies to I = 21.50. Therefore, the simple interest due is $21.50.

The number of bacteria in a refrigerated food product is given byN(T)=27T2−148T+100,5
The number of bacteria in the refrigerated food product at T = 3 is -100.5.
The number of bacteria in a refrigerated food product is given by the equation N(T) = 27T^2 - 148T + 100.5. This equation can be used to determine the number of bacteria in the product at any given time, T.
To find the number of bacteria at a specific time, simply plug in the value of T into the equation and solve for N(T). For example, if we want to find the number of bacteria at T = 3, we would plug in 3 for T and solve:
N(3) = 27(3)^2 - 148(3) + 100.5
N(3) = 27(9) - 444 + 100.5
N(3) = 243 - 444 + 100.5
N(3) = -100.5
Therefore, the number of bacteria in the refrigerated food product at T = 3 is -100.5. It is important to note that the number of bacteria cannot be negative, so this equation may not be valid for all values of T. It is important to check the validity of the equation for the specific time period in question.

What lump sum must be invested at 7%, compounded monthly, for
the investment to grow to $61,000 in 13years?
The lump sum that must be invested at 7% compounded monthly for the investment to grow to $61,000 in 13 years is $25,447.09.
To find the lump sum that must be invested at 7% compounded monthly for the investment to grow to $61,000 in 13 years, we can use the formula for compound interest;
A = P(1 + r/n)^(nt)
Where:
- A is the final amount
- P is the initial principal amount
- r is the annual interest rate
- n is the number of times interest is compounded per year
- t is the number of years
Plugging in the given values, we get:
61,000 = P(1 + 0.07/12)^(12*13)
Solving for P, we get:
P = 61,000 / (1 + 0.07/12)^(12*13)
P = 61,000 / (1.00583)^156
P = 61,000 / 2.39717
P = 25,447.09

At a carnival game, it cost Taylor $6 to toss 63 rings. Fill out a table of equivalent ratios and plot the points on the coordinate axes provided.
Graph is the collection of all points whose coordinates satisfy a given relation (such as a function).
What is coordinates?Coordinates of a point in a 2D plane, also known as cartesian coordinates, are two numbers or sometimes a combination of a letter and a number that tell us the exact location of a specific point on a grid. Here, the grid is known as a coordinate plane.
Let tosses be x and and dollars be y
Then we have, (x, y) as (63, 6)
So if in 6 dollars you get 63 tosses then 1 dollar you get = 63/6 = 10.5 tosses.
Then in 2 dollars we have = 10.5 × 2 = 21 tosses
As 21 tosses = 2 dollars
Then 42 tosses = 2 × 2 = 4 dollars
Thus, we have the table:
[tex]\boxed{\begin{array}{cc}\underline{\text{Tosses}}&\underline{\text{dollars}}&\\ \boxed{10.5}&2&\\42&\boxed4&\\63&6&\end{array}}[/tex]
To graph the given points, just correspond x as tosses and y as dollars.
