What is greatest common factor?
The largest factor that all of the numbers share is known as the greatest common factor (GCF) of a set of numbers.
One way to do this is to list the factors of both 36 and 90 and find their common factors. The factors of 36 are:
1, 2, 3, 4, 6, 9, 12, 18, 36
The factors of 90 are:
1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90
The common factors of 36 and 90 are:
1, 2, 3, 6, 9, 18
Therefore, the greatest common factor of 36 and 90 is 18.
To reduce the fraction 36/90, we can divide both the numerator and denominator by 18:
36 ÷ 18 = 2
90 ÷ 18 = 5
So, 36/90 can be reduced to 2/5 by dividing both the numerator and denominator by their greatest common factor, which is 18.

Write the absolute value equation that has the following solutions.
One solution: x = 15
The absolute value equation is:
|x - 15| = 0
How to write the absolute value equation?We want an absolute value equation that only has the solution x = 15.
So we must have something equal to zero (so we avoid the problem with the signs that we can have with other numbers)
So the equation will be something like:
|x - a| = 0
And the solution is 15, so:
|15 - a | = 0
then a = 15

Antoni Gaudi purchased a bedroom set with an installment loan that has an APR of 12%. The bedroom set sells for $2,650. The store financing requires a 15% down payment and 42 monthly payments. What is the finance charge?
The finance charge for Antoni Gaudi's bedroom set purchase is $731.08.
What is an installment?An installment refers to a sum of money that is paid back in parts over a period of time, typically with interest.
Define loan?A loan is a financial agreement between a lender and a borrower, in which the lender provides the borrower with a specific amount of money or assets, which the borrower agrees to pay back with interest over a predetermined period of time. Loans can be used for a variety of purposes, such as purchasing a home, starting a business, or paying for education.
Based on the given information, the bedroom set sells for $2,650, and the financing requires a 15% down payment, which is $397.50 ($2,650 x 0.15).
Therefore, the amount financed is $2,252.50 ($2,650 - $397.50).
To calculate the finance charge, we need to know the total amount of payments Antoni Gaudi will make over the 42-month period. Each monthly payment can be calculated using the following formula:
Monthly Payment = (Amount Financed x (APR/12)) / (1 - (1 + APR/12)^-n)
Where:
APR is the annual percentage rate (12% in this case)
n is the total number of payments (42 in this case)
Plugging in the values, we get:
Monthly Payment = ($2,252.50 x (0.12/12)) / (1 - (1 + 0.12/12)^-42)
= $70.99 (rounded to the nearest cent)
Therefore, the total amount of payments Antoni Gaudi will make over the 42-month period is $2,983.58 ($70.99 x 42).
The finance charge can be calculated as follows:
Finance Charge = Total Payments - Amount Financed
= $2,983.58 - $2,252.50
= $731.08
Therefore, the finance charge for Antoni Gaudi's bedroom set purchase is $731.08.

Becky would have to invest 43,478 to be able to take the 200,000. The solution has been obtained by using the simple interest.
What is simple interest?
Simple interest is the cost of borrowing that is determined by utilising only the original principle and a constant interest rate.
We are given the following information:
Amount = 200,000
Interest rate = 9%
Time = 40 years
Let the principal be x.
So, we get
⇒ Amount = Principal + Interest
⇒ 200,000 = x + (9% of x) * 40
⇒ 200,000 = x + 0.09x * 40
⇒ 200,000 = x + 3.6x
⇒ 200,000 = 4.6x
⇒ x = 43,478

the parallelogram is 6 m, then what is the
length?
The area of a figure in the shape of a parallelogram is 74.4 m2 . If the height of the parallelogram is 6 m, the length of the parallelogram is 12.4 meters.
Describe Parallelogram?A parallelogram is a four-sided plane figure with opposite sides parallel and equal in length. It is a special type of quadrilateral, which is a polygon with four sides.
The opposite sides of a parallelogram are parallel, which means they have the same slope and never intersect. The opposite sides are also equal in length, which means they have the same distance between them.
The adjacent angles of a parallelogram are supplementary, which means they add up to 180 degrees. This property is known as the parallelogram law, which states that the sum of the squares of the diagonals of a parallelogram equals the sum of the squares of its sides.
The area of a parallelogram can be calculated by multiplying the base by the height. The base is one of the parallel sides, and the height is the perpendicular distance between the base and the opposite side.
The area (A) of a parallelogram is given by the formula:
A = base x height
where the base is the length of one of the sides of the parallelogram and the height is the perpendicular distance between the base and the opposite side.
In this problem, we are given the area of the parallelogram as 74.4 m² and the height as 6 m. Let the length of the parallelogram be denoted by b. Then, we can use the formula for the area of a parallelogram to write:
74.4 m² = b x 6 m
Solving for b, we get:
b = 74.4 m² / 6 m
b = 12.4 m
Therefore, the length of the parallelogram is 12.4 meters.

The number of deer on an island is given by D=200+100sin( 2 π x), where x is the number of years since 2000. Which is the first year after 2000 that the number of deer reaches 150 ?
Therefore, the first Leap year after 2000 that the number of deer reaches 150 is 2000.1, or 2000 and 1/10 of a year.
What are a leap year and a year?If you sum up all the days on a calendar from January to December, there are 365 in a regular year. But about every four years, February has 29 days rather than 28. Therefore, a year has 366 days. There is a term for it: a leap year.
We must find x in the equation D=150 in order to determine the year that the number of deer exceeds 150 for the first time after 2000.
150=200+100sin(2πx)
Subtracting 200 from both sides, we get:
-50 = 100sin(2πx)
Dividing both sides by 100, we get:
-0.5 = sin(2πx)
To find the value of x that satisfies this equation, we can take the inverse sine of both sides:
sin⁻¹(-0.5) = 2πx
Using a calculator, we find that sin⁻¹(-0.5) = -π/6.
-π/6 = 2πx
Solving for x, we get:
x = -1/12
Since x is the number of years since 2000, we need to add 1/12 to find the first year after 2000 that the number of deer reaches 150:
2000 + 1/12 ≈ 2000.1

Find the Taylor Polynomial 3P x (up to3
x ) for( ) x

We have to find the Taylor Polynomial of $f(x)=e^x$ up to the third degree, centered at $x=0$.
The Taylor Polynomial is given by:
(x)=∑
k=0
n
k!
f
(k)
(a)
(x−a)
k
where $f^{(k)}(a)$ is the $k$th derivative of $f(x)$ evaluated at $a$.
Using this formula, we can find the Taylor Polynomial as follows:
\begin{align*}
f(x) &= e^x \
f'(x) &= e^x \
f''(x) &= e^x \
f'''(x) &= e^x \
\end{align*}
Evaluating each derivative at $x=0$, we get:
\begin{align*}
f(0) &= e^0 = 1 \
f'(0) &= e^0 = 1 \
f''(0) &= e^0 = 1 \
f'''(0) &= e^0 = 1 \
\end{align*}
Substituting these values into the formula for the Taylor Polynomial, we get:
\begin{align*}
P_3(x) &= \frac{f(0)}{0!}(x-0)^0 + \frac{f'(0)}{1!}(x-0)^1 + \frac{f''(0)}{2!}(x-0)^2 + \frac{f'''(0)}{3!}(x-0)^3 \
&= 1 + x + \frac{x^2}{2} + \frac{x^3}{6}

Therefore, the Taylor Polynomial of $f(x)=e^x$ up to the third degree, centered at $x=0$, is $P_3(x) = 1 + x + \frac{x^2}{2} + \frac{x^3}{6}$.

What fractions are close to 1 than to 0
The answer of the given question based on the fraction is , a value that is greater than 1/2.
What is Fraction?A fraction is mathematical expression that represents part of whole or ratio between the two numbers. It is expressed in the form of a ratio of two integers, with a numerator and a denominator separated by a horizontal or slanted line called a fraction bar.
Fractions that are closer to 1 than to 0 have a value that is greater than 1/2. This is because 1/2 is exactly halfway between 0 and 1 on the number line.
So, any fraction that has a numerator greater than its denominator is closer to 1 than to 0. For example:
2/3 is closer to 1 than to 0 because it is greater than 1/2
7/8 is closer to 1 than to 0 because it is greater than 1/2
3/4 is closer to 1 than to 0 because it is greater than 1/2
On the other hand, fractions that have a value less than 1/2 are closer to 0 than to 1. For example:
1/4 is closer to 0 than to 1 because it is less than 1/2
3/10 is closer to 0 than to 1 because it is less than 1/2
2/5 is closer to 0 than to 1 because it is less than 1/2

What is a scale factor?In mathematics, a scale factor is a number that scales, or multiplies, some quantity. In the context of geometry, the scale factor is the ratio of lengths in a pair of similar geometric figures or the ratio of the areas of two similar geometric figures. When one figure is transformed into another by dilation, the scale factor is the ratio of the lengths of corresponding sides. The scale factor can be greater than 1, less than 1, or equal to 1 (meaning no change in size).
We can determine the scale factor by comparing the lengths of sides of the two triangles.
The length of side AB is,
AB = [tex]\sqrt{[(1 - (-1))^2 + (1 - (-1))^2]}[/tex] = [tex]\sqrt{8}[/tex]
Similarly the length of side A'B' is,
A'B' = [tex]\sqrt{[(3 - (-3))^2 + (3 - (-3))^2]}[/tex] = [tex]\sqrt{72}[/tex]
So the scale factor will be,
A'B' / AB = [tex]\frac{\sqrt{72} }{\sqrt{8} }[/tex] = [tex]\sqrt{9}[/tex] = 3
Therefore, the scale factor used to dilate triangle ABC into triangle A'B'C' is 3.

What is a confidence interval?The mean of your estimate plus and minus the range of that estimate constitutes a confidence interval.
Within a specific level of confidence, this is the range of values you anticipate your estimate to fall within if you repeat the test.
The 95% confidence level is the most popular, however other levels, such as 90% or 99%, are occasionally used when computing confidence intervals.
So, let X represent the amount of time (in seconds) needed to complete a 100-meter race with Tom.
His population's mean 100-meter race finishing time falls within a 99% confidence interval of 12.8081 and 15.5919.

The 1st and 2nd terms of this Fibonacci sequence, given the 3rd and 6th terms would be 2 and 5.
How to find the Fibonacci sequence terms ?Let's denote the first and second terms of the Fibonacci sequence as F1 and F2. The Fibonacci sequence is defined by the recurrence relation:
F(n) = F(n-1) + F(n-2)
We are given that the 3rd term (F3) is 7 and the 6th term (F6) is 31. We can use this information to set up the following equations:
F3 = F2 + F1 = 7
F6 = F5 + F4 = 31
We can also express F4 and F5 in terms of F1 and F2:
F4 = F3 + F2 = (F2 + F1) + F2 = F1 + 2F2
F5 = F4 + F3 = (F1 + 2F2) + (F2 + F1) = 2F1 + 3F2
Now, let's substitute equation (4) into equation (2):
F6 = 2F1 + 3F2 + F1 + 2F2 = 31
3F1 + 5F2 = 31
By trial and error, we can find the possible values for F1 and F2 that satisfy this equation:
F1 = 1, F2 = 6: 3(1) + 5(6) = 3 + 30 = 33 (not a solution)
F1 = 2, F2 = 5: 3(2) + 5(5) = 6 + 25 = 31 (solution)
The solution is F1 = 2 and F2 = 5, so the first two terms of the Fibonacci sequence are 2 and 5.

(2x^2+6x-11)-(5x^2-x+7)
Answer:
-3x² +7x - 18
Step-by-step explanation:
Subtraction of expression:
Multiply each term of 5x² - x + 7 by (-1)
2x² + 6x - 11 - (5x² - x + 7) = 2x² + 6x - 11 - 5x² + x - 7
Combine like terms. Like terms have same variable with same exponent.
2x² and (-5x²) are like terms. 2x² - 5x² = -3x²
6x and x are like terms. 6x + x = 7x
-11 and (-7) are constants. -11 - 7= -18
= 2x² - 5x² + 6x + x - 11 - 7
= -3x² + 7x - 18
6 = 1/2 × z what is the value of z
Answer:
To solve for the value of z in the equation 6 = 1/2 × z, we can use algebraic manipulation. First, we can multiply both sides of the equation by 2 to eliminate the fraction:
2 × 6 = 2 × (1/2 × z)
Simplifying the right side:
12 = z
Therefore, the value of z is 12.
