Answer:
The equivalent factored form of this equation is (x² + 49)(x - 6)
Step-by-step explanation:
x³ - 6x² + 49x - 294
First, group the first and second terms together and group the last two terms together.
(x³ - 6x²) + (49x - 294)
Find the greatest common factor of both parentheses and factor them.
x²(x - 6) + 49(x - 6)
Now, since the two terms in the parentheses are the same, then we have factored the equation correctly.
So, the factored form of the equation is (x² + 49)(x - 6)
Answer:(x-6)(x+7i)(x-7i)
Step-by-step explanation:
(x-6)(x^2+49)=(x-6)(x^2-(-49)
(x-6)(x^2-(7i)^2)
(x-6)(x+7i)(x-7i)

Find the unknown side length, x. Write your answer in simplest radical form.
A. 4132
B. 22
C. 16/5
D. 16 V13
Answer:
C
Step-by-step explanation:
Use the pythagorean theorem.
32^2+b^2=48^2
1024+b^2=2304
Subtract 1024
b^2=1280
Square root
b=sqrt(1280)
Now simplify sqrt(1280)
sqrt(1280) = sqrt(256*5)
You can take the square root of 256 since it is a perfect square so take it out of the radical.
sqrt(256*5)=16sqrt(5)
So the answer is c, 16\(\sqrt{5}\)
Answer:
C. 16/5
Step-by-step explanation:
pythagorean theorem
a^2 + b^2 = c^2
divide 48 and 32 by 16
a= 2 c= 3
4 + b^2 = 9
b^2 = 5
b = √5
then multiply 16 with √5
which =

The elimination of dominated strategies is an iterative technique in which any alternative that is dominated by another alternative is deleted from further consideration.
The correct answer is {(D,Y)}
It is important to recognize that a strategy is said to be dominated by another strategy if it performs worse than the other strategy for all possible responses from the other player(s), regardless of what the other player does. the elimination of dominated strategies is given figure can be represented as: This game is solved through the elimination of dominated strategies. We solve this by using the following iterative steps: Dominated Strategy Elimination In this step, we eliminate all the strategies which are dominated by another strategy.
The payoffs in the lower-right corner are (-1, -1) in (B,Y) and (-2, -1) in (C,Y). Therefore, strategy (C,Y) dominates (B,Y) and hence we eliminate (B,Y) from our list of strategies. This leads to a new matrix as shown below: Therefore, strategy (D,X) dominates (D,Y) and hence we eliminate (D,Y) from our list of strategies. This leads to the following matrix as shown below: Step 3: Final Decision We are now left with only one strategy, (D, Y). Hence, it is the only dominant strategy in this game and the solution to the game is (D, Y). Therefore, the solution to the game in Figure 2 by the elimination of dominated strategies is (D, Y).

Write three more equations for 1ị that are all true and all different. Use only fractions with a denominator of 3 in your equations. 1 2/3 =1 2/3 =1 2/3 =
That we added a real number (2/3) and subtracted a real number (3), but the imaginary part of the result is still (5/3)i.
First, let me clarify what 1ị represents. In mathematics, the imaginary unit i is defined as the square root of -1. Therefore, 1ị means 1 times the imaginary unit i.
To write three more equations for 1ị that are all true and all different, we can use the fact that i satisfies the equation i^2 = -1. We can also use the fact that any multiple of i, such as 2i, 3i, and so on, is also an imaginary number. Finally, we can use the fact that adding or subtracting real numbers to or from an imaginary number does not affect the imaginary part of the number.
Here are three possible equations for 1ị:
(2 + 1/3)i = 1ị + 2i
Explanation: We can add 2 times the imaginary unit i to 1 times the imaginary unit i to get 3 times the imaginary unit i, which is equal to (2 + 1/3) times the imaginary unit i.
(-1/3)i = 1ị - 4/3i
Explanation: We can subtract 4/3 times the imaginary unit i from 1 times the imaginary unit i to get -1/3 times the imaginary unit i.
(5/3)i = 1ị + 2/3 + 3i - 3
Explanation: We can add 2/3 and 3i - 3 to 1 times the imaginary unit i to get (5/3) times the imaginary unit i. Notice that we added a real number (2/3) and subtracted a real number (3), but the imaginary part of the result is still (5/3)i.

In ΔUVW, the measure of ∠W=90°, WV = 65, VU = 97, and UW = 72. What ratio represents the sine of ∠V?
The sine of angle V is 97/72. The length of side VW is 65 units.
To find the sine of angle V, we need to use the ratio of the length of the side opposite angle V to the length of the hypotenuse. In this case, side VU is opposite angle V, and hypotenuse UW is the longest side of the right triangle.
Using the Pythagorean Theorem, we can find the length of side VW:
VW² = UW² - VU²
VW² = 72² - 97²
VW² = 5184 - 9409
VW² = 4225
VW = 65
Now we can use the sine ratio:
sin(V) = opposite/hypotenuse = VU/UW
sin(V) = 97/72
Therefore, the ratio that represents the sine of ∠V is 97/72.

What is the slope of the line that passes through the points (9, 5)(9,5) and (21, -5)(21,−5)? Write your answer in simplest form.
The slope of a line is determined by the formula:
(y2 - y1) / (x2 - x1)
So for the points (9, 5) and (21, -5), the slope would be:
(-5 - 5) / (21 - 9) = -10 / 12 = -5/6
So the slope of the line that passes through the points (9, 5) and (21, -5) is -5/6 in simplest form.
Figure LMNO is a reflection of HIJK. Which angle is congruent to ZH?
The angle formed by this intersection point and the corresponding point on LMNO is congruent to ZH.
In this case, we have two figures, LMNO and HIJK, and we know that LMNO is a reflection of HIJK. This means that there is an axis of reflection that maps HIJK onto LMNO.
When a shape is reflected across a line of symmetry, its angles are preserved. That is, if two angles in the original shape are congruent, then their images in the reflected shape are also congruent.
In this case, ZH is an angle in HIJK, and we want to find the angle in LMNO that corresponds to it. To do this, we need to find the line of symmetry that maps HIJK onto LMNO.
Once we have identified this line, we can draw the perpendicular bisector of ZH and find where it intersects the line of symmetry. The angle formed by this intersection point and the corresponding point on LMNO is congruent to ZH.

The Bainters want to know how much they would pay on their loan each year as well as how much they would pay on their loan after 5 years, 10 years, 15 years, and 30 years. They also want to determine how much they would pay in interest on their loan when they repay the entire loan.
What are the amounts?
Your answer should include (remember to show or explain your calculations)
- the total amount paid in loan payments after 1 year
- the total amount paid in loan payments after 5 years
- the total amount paid in loan payments after 10 years
- the total amount paid in loan payments after 15 years
- the total amount paid in loan payments after 30 years
- the total amount of interest paid on the loan when it is repaid
The total amount of interest paid on the loan when it is repaid is $93,255.08. This is the difference between the total amount paid in loan payments and the loan amount of $100,000.
What is the interest?
Interest is the price you pay to borrow money or the cost you charge to lend money. Interest is most often reflected as an annual percentage of the amount of a loan. This percentage is known as the interest rate on the loan.
To calculate the amounts the Bainters would pay on their loan, we need to know the loan amount, the interest rate, and the loan term. Without this information, we cannot provide exact amounts, but we can illustrate how to calculate them using a hypothetical loan amount and interest rate.
For example, suppose the Bainters borrow $100,000 at an annual interest rate of 5% for a 30-year term. Using an amortization calculator, we can calculate the loan payments and total interest paid as follows:
The total amount paid in loan payments after 1 year is $6,158.54. This includes both principal and interest payments.
The total amount paid in loan payments after 5 years is $33,786.39. This includes both principal and interest payments.
The total amount paid in loan payments after 10 years is $69,267.75. This includes both principal and interest payments.
The total amount paid in loan payments after 15 years is $107,212.01. This includes both principal and interest payments.
The total amount paid in loan payments after 30 years is $193,255.08. This includes both principal and interest payments.
The total amount of interest paid on the loan when it is repaid is $93,255.08. This is the difference between the total amount paid in loan payments and the loan amount of $100,000.
These amounts are based on the assumption of a fixed interest rate and a fixed loan term. If the interest rate or the loan term changes, the amounts paid on the loan will also change.
Hence, The total amount of interest paid on the loan when it is repaid is $93,255.08. This is the difference between the total amount paid in loan payments and the loan amount of $100,000.

44 cu. cm of wire is drawn into a wire of diameter 2 mm , the length of wire will be _____.
Given:
44 cu. cm of wire is drawn into a wire of diameter 2 mm.
To find:
The length of the wire.
Solution:
We know that,
1 cm = 10 mm
1 cu. cm = 1000 cu. mm
We have, a wire of cylindrical shape.
Volume of the wire = 44 cu. cm
= 44000 cu. mm
Radius of the wire = 2 mm
Volume of a cylinder is:
\(V=\pi r^2h\)
Where, r is the radius and h is the height.
Putting V=44000, \(\pi=\dfrac{22}{7}\) and r=2, we get
\(44000=\dfrac{22}{7}\times 2^2\times h\)
\(44000\times \dfrac{7}{22}=4h\)
\(14000=4h\)
Divide both sides by 4.
\(\dfrac{14000}{4}=h\)
\(3500=h\)
Therefore, the length of the wire is 3500 mm or 350 cm.
A rancher wants to fence in an area of 1,300,000 square feet in a rectangular field and then divide it in half with a fence down the middle parallel to one side. What is the shortest length of fence that the rancher can use
The shortest length of fence is thus equal to P1 = x + 1,300,000/x.
Let the width of the rectangular field be "x" feet and the length be "y" feet, then the area of the field, A = x y square feet. The area of the field is given as 1,300,000 square feet, so we can write; x y = 1,300,000 Therefore, y = 1,300,000/x feet. Now, if we divide the rectangular field into two halves parallel to one side, we can write the new dimensions of each half as follows: Half 1: Length = x, Width = y/2 = 1,300,000/2x = 650,000/x Half 2: Length = x, Width = y/2 = 1,300,000/2x = 650,000/x
The total length of fence needed to enclose the rectangular field is given by; P = 2x + 2y = 2x + 2(1,300,000/x)P = 2x + 2(1,300,000/x)The total length of fence needed to divide the rectangular field into two halves is given by;P1 = x + 2(650,000/x)P1 = x + 1,300,000/x Thus, the shortest length of fence that the rancher can use is the length of the fence needed to divide the field into two halves. Therefore;P1 = x + 1,300,000/x.
The shortest length of fence is thus equal to P1 = x + 1,300,000/x.

suppose the "n" on the left is written in regular 12-point font. find a matrix a that will transform n into the letter on the right, which is written in ‘italics’ in 16-point font.
The matrix A that transforms the letter 'n' in regular 12-point font to the italicized 'n' in 16-point font can be determined by scaling and shearing operations.
What matrix transformation can be applied to convert 'n' to italicized 'n'?To achieve the desired transformation, we can apply a combination of scaling and shearing operations using a 2x2 matrix. Let's denote this matrix as A.
To find the specific values of the matrix A, we need to consider the differences between the regular 'n' and the italicized 'n' in terms of scaling and shearing.
The italicized 'n' is slanted compared to the regular 'n'. This slant can be achieved by applying a shear transformation along the x-axis.
We can determine the values of A by examining the specific slant and size changes of the italicized 'n' compared to the regular 'n'.
The matrix A will consist of scaling factors and shear coefficients that capture the desired transformation. The exact values of the matrix elements will depend on the specific slant and size adjustments required for the italicized 'n'.
To obtain the matrix A, we would need to analyze the italicized 'n' in 16-point font and compare it to the regular 'n' in 12-point font to determine the necessary scaling and shearing parameters.
