Write a polynomial of least degree with real coefficients and with the root -20-7i. Write your answer using the variable x and in standard form with a leading coefficient of 1.
Answer:
Step-by-step explanation:
Logically, if a polynomial of real coefficients has a complex root, it’s conjugate is a root as well. That means if -20-7i is a root, -20+7i is also a root. Also, since we’re dealing with minimal degree, we wish to construct a quadratic expression with such roots. To do this, we can use Vieta’s formulas, which relates the trinomial coefficients with its roots. The two roots added together is -b/a in ax^2 + bx + c, and the two roots multiplied together is c/a. The two roots added together is -40. The two roots multiplied together is 449. So, our quadratic expression is x^2+40x+449
This figure is made from a part of a square and a part of a circle.
What is the area of this figure, to the nearest square unit?
Perimeter of the given polygon figure will be 38 units.
What exactly is a polygon in mathematics?
A closed, two-dimensional, flat, closed polygon is a shape that is constrained by geometry and has straight sides. Its sides don't curve inward at all. Another term for a polygon's sides is its polygonal edges. The points where two sides converge are known as a polygon's vertices (or corners).
Perimeter of a polygon = Measure of the circumference of the polygon
From the figure attached,
Perimeter of the figure = measure of the three straight lines + measure of the circumference of the quarter circle
Measure of linear sides = 5 + 10 + 10 + 5 = 30 units
Circumference of the quarter circle = 1/4(2πr)
= 1/2(π)(5)
= 7.85 units
Perimeter of the figure = 30 + 7.85
= 37.85
≈ 38 units
Therefore, perimeter of the given figure will be 38 units.

22 hours.
How long did Eudora spend running, and how long did she spend flying using her jetpack?
Eudora spent 0 hours running and 2 hours flying using her jetpack.
Let's use the formula: time = distance / speed.
Let x be the time Eudora spent running and y be the time she spent flying using her jetpack.
From the problem, we know that:
Eudora ran at an average speed of 12 km/h, so she covered a distance of 12x kilometers while running.
Eudora flew at an average speed of 76 km/h, so she covered a distance of 76y kilometers while flying.
The total distance she traveled was 120 kilometers, so: 12x + 76y = 120.
The entire trip took 2 hours, so: x + y = 2.
We can use the second equation to solve for x: x = 2 - y.
Substituting into the first equation, we get: 12(2 - y) + 76y = 120.
Simplifying the equation, we get: 152 - 64y = 120.
Solving for y, we get: y = 2 hours.
Substituting into x = 2 - y, we get: x = 0 hours.
Therefore, Eudora spent 0 hours running and 2 hours flying using her jetpack.

4x
If the value of x is 4, the quadrilateral meets all the requirements of a parallelogram and will be a parallelogram.
What is a quadrilateral?A quadrilateral is a four-sided shape with straight line segments as its sides. It is a two-dimensional shape with four angles, each measuring 90°. Quadrilaterals can be categorized into different shapes such as squares, rectangles, parallelograms, trapezoids, rhombuses, and kites.
A parallelogram is a four-sided shape with opposite sides parallel and equal in length. To find the value of x that makes the quadrilateral a parallelogram, we need to use the property of a parallelogram, which states that the opposite sides of a parallelogram are equal in length.
Therefore, we need to equate the opposite sides of the quadrilateral: 6x-8=4x. After solving this equation, we get x=4. Thus, the value of x that makes the quadrilateral a parallelogram is 4.
In order for a quadrilateral to be a parallelogram, opposite sides must be parallel. Using this property, we can set the opposite sides equal to each other and solve for x.
[tex]$2x + 5 = 3x - 2$[/tex]

By the given definition of matrix A, the value of the matrix A⁻¹ is [tex]\left[\begin{array}{ccc}-1&0&1&2&-1&-2&0&0&-1\end{array}\right][/tex] and it is true that AA⁻¹ = I₃.
Calcuting the matrix A⁻¹Given that
[tex]A = \left[\begin{array}{ccc}1&0&2\\1&1&0\\1&0&1\end{array}\right][/tex]
To find the inverse of A, we can use the following formula:
A⁻¹ = (1/|A|) adj(A)
where |A| is the determinant of A and adj(A) is the adjugate matrix of A.
First, let's calculate the determinant of A:
|A| = 1(1×1 - 0×0) - 0(1×0 - 0×1) + 2(1×0 - 1×1)
|A| = -1
Next, we need to find the adjugate matrix of A.
To do this, we need to find the matrix of cofactors of A, then take its transpose:
[tex]C = \left[\begin{array}{ccc}1&-2&0&0&1&0&-1&2&1\end{array}\right]\\[/tex]
adj(A) = [tex]C^T = \left[\begin{array}{ccc}1&0&-1&-2&1&2&0&0&1\end{array}\right][/tex]
Now we can calculate A⁻¹ using the formula:
A⁻¹ = (1/|A|) adj(A)
So, we have
[tex]A^{-1} = (-1) \left[\begin{array}{ccc}1&0&-1&-2&1&2&0&0&1\end{array}\right] = \left[\begin{array}{ccc}-1&0&1&2&-1&-2&0&0&-1\end{array}\right][/tex]
Checking whether AA⁻¹ = I₃Finally, we can check whether AA⁻¹ = I₃ using
[tex]A^{-1}A = \left[\begin{array}{ccc}-1&0&1&2&-1&-2&0&0&-1\end{array}\right] \left[\begin{array}{ccc}1&0&2&1&1&0&1&0&1\end{array}\right] = \left[\begin{array}{ccc}1&0&0&0&1&0&0&0&1\end{array}\right] = I_3[/tex]
Therefore, we have found the inverse of A and verified that AA⁻¹ = I₃.

You travel in a car at an average rate of 55 miles per hour on the highway and 35 miles per hour in the city.
a. How long does it take you to travel 16.5 highway miles and 7 city miles?
b. How long does it take you to travel 44 highway miles and 28 city miles?
According to the given information, it takes 0.5 hours to travel 16.5 highway miles and 7 city miles and 1.6 hours to travel 44 highway miles and 28 city miles.
What is the average rate?
The average rate is a measure of the average speed at which something occurs over a period of time. It is calculated by dividing the total amount of something by the total time it took to occur.
The formula for the average rate or average speed is:
Average speed = Total distance traveled / Total time taken
a. To find the time it takes to travel 16.5 highway miles and 7 city miles, we can use the formula:
time = distance/speed
The time it takes to travel 16.5 highway miles is:
time on highway = 16.5 / 55 = 0.3 hours
The time it takes to travel 7 city miles is:
time in city = 7 / 35 = 0.2 hours
The total time it takes to travel both distances is:
total time = time on highway + time in city = 0.3 + 0.2 = 0.5 hours
Therefore, it takes 0.5 hours (or 30 minutes) to travel 16.5 highway miles and 7 city miles.
b. To find the time it takes to travel 44 highway miles and 28 city miles, we can use the same formula:
time on highway = 44 / 55 = 0.8 hours
time in city = 28 / 35 = 0.8 hours
total time = time on highway + time in city = 0.8 + 0.8 = 1.6 hours
Therefore, it takes 1.6 hours (or 96 minutes) to travel 44 highway miles and 28 city miles.

N=6, p=0.3, x<4
P(x<4) =
Answer:
Step-by-step explanation:
To find P(x<4), we need to use the cumulative distribution function (CDF) of the binomial distribution.
For N = 6 and p = 0.3, the probability mass function (PMF) is:
P(X = k) = (6 choose k) * 0.3^k * 0.7^(6-k)
where (6 choose k) is the binomial coefficient.
Using this formula, we can find the probabilities for each value of X less than 4:
P(X = 0) = (6 choose 0) * 0.3^0 * 0.7^6 ≈ 0.1176
P(X = 1) = (6 choose 1) * 0.3^1 * 0.7^5 ≈ 0.3025
P(X = 2) = (6 choose 2) * 0.3^2 * 0.7^4 ≈ 0.3241
P(X = 3) = (6 choose 3) * 0.3^3 * 0.7^3 ≈ 0.1852
Therefore, P(x<4) is the sum of these probabilities:
P(x<4) = P(X=0) + P(X=1) + P(X=2) + P(X=3) ≈ 0.9294
So the probability of getting less than 4 successes in 6 trials with a success probability of 0.3 is approximately 0.9294.

From the information shown in the diagram, we have that;
Hypotenuse side = 21
Adjacent side = 12. 6
Opposite side = 2(x)
Substitute the values
x² = 21² - 12.6²
find the squares
x² = 441 - 158. 76
subtract the values
x = 16. 8
But, we have that this value is the diameter but x as shown is the radius.
Radius, x = 16. 8 /2 = 8. 4

Hello, If 1lb - $3.40 would 0.274lb equal 2.647? I was struggling with this question, At first I did 0.34(y) and 0.1(x) but I learned that going up from 0.34 every 0.1 decimal will not help because I am trying to figure out 0.274 so then I am trying to see if $2.4 would work. Thank you. Oops, I am in middle school not college, Apologies.

The box-and-whisker plot shows that the dataset has a median of approximately 5.5 and is relatively symmetric, with the middle 50% of the data falling between approximately 4 and 7.
The box-and-whisker plot offers a visual summary of the distribution of the given dataset. The following is one way to understand the plot:
The median, which is the midway number when the data is organised from least to largest, is shown by the line inside the box. The median in this situation is roughly 5.5.
The box's bottom edge corresponds to the first quartile (Q1) and its top edge to the third quartile, and it represents the middle 50% of the data (Q3). The interquartile range is the space between Q1 and Q3 (IQR). In this instance, Q1 is roughly 4 and Q3 is roughly 7, hence the IQR is roughly 3.
The whiskers reach from the box's boundaries to the dataset's lowest and largest values that aren't regarded as outliers. Although there are many different definitions of an outlier, it is generally accepted that any number that is more than 1.5 times the IQR below Q1 or above Q3 qualifies as an outlier. There aren't any anomalies in this circumstance.
Individual data points outside the box and whiskers are shown as dots above and below the whiskers. There are no such data points in this situation.
Hence, the box-and-whisker plot reveals that the dataset is very symmetrical and has a median of about 5.5, with the middle 50% of the data ranging between roughly 4 and 7.

A rainwater tank has a diameter of 160 cm and a height of 190 cm. The tank is half full. The water is used at a rate of 25,5 litres per day. In how many days will the tank run dry, assuming that no rain falls in that time?
It will run dry after 141.7 days.
In how many days will the tank run dry?The rainwater tank has a diameter of 160 cm and a height of 190 cm, then its volume is:
V = 3.14*(180cm)*(160cm/2)² = 3,617,280 cm³
We know that 1 L = 1000 cm³
then:
3,617,280 cm³ = 3,617.280 L
The water is used at a rate of 25,5 litres per day, so after x days there is:
W = 3,617.280 - 25.5*x liters
It is zero when:
0 = 3,617.280 - 25.5*x
x = 3,617.280/25.5
x = 141.7 days.
