Answer:

[tex]-\sqrt{2}[/tex] and [tex]\sqrt{13}[/tex]

Step-by-step explanation:

Given a polynomial with rational coefficients, its irrational and complex roots would occur in conjugate pairs.

For example, if the roots of a polynomial are 2 + [tex]\sqrt{3}[/tex], 3 and 4 - 3i, then 2 - [tex]\sqrt{3}[/tex], and 4 + 3i are also roots of the polynomial.

Therefore, since the given polynomial has rational coefficients and some of its roots are , [tex]\sqrt{2}[/tex] and  - [tex]\sqrt{13}[/tex], then -[tex]\sqrt{2}[/tex] and [tex]\sqrt{13}[/tex] are also roots of the polynomial.

The scale factor of the image is 1/4 or 0.25.

What is scale factor?

The ratio of the scale of an original thing to a new object that is a representation of it but of a different size is known as a scale factor (bigger or smaller).

To solve this question, use the coordinates of WX and W'X' as points of reference.

From the diagram, it can be obtained that -

W(-8,8) and X(8,0)

W'(-2,2) and X'(2,0)

First, calculate distance for WX -

Distance formula is -

d = √(x2-x1)^2+(y2-y1)^2

Distance for WX -

d1 = √(8+8)^2+(0-8)^2

d1 = √(16)^2+(-8)^2

d1 = √256+64

d1 = √320

d1 = 17.88

Distance for W'X' -

d2 = √(2+2)^2+(0-2)^2

d2 = √(4)^2+(-2)^2

d2 = √16+4

d2 = √20

The scale factor is then calculated using -

Scale = W'X'/WX

Scale = d2/d1

Substitute values of d1 and d2 -

Scale =√20/√320

Scale = √(20/320)

Scale = √1/16

Scale = 1/4

Therefore, the scale value is 0.25.

Answer:

Yes (you are 75 mi from epicenter). Travel at least 7.91 mi south

Step-by-step explanation:

See the attached image.

The epicenter is the point at the upper right of the drawing.  You are 60 miles west (left) and 45 miles south (down) from the epicenter.  A right triangle is formed--apply the Pythagorean Theorem, (leg)^2 + (leg)^2 = (hypotenuse)^2.

[tex]x^2=60^2+45^2\\\\x^2=3600+2025\\\\x^2=5625\\\\x=\sqrt{5625}=75[/tex] This is within 80 mi, so you feel the quake.

Now (see image2) you go  y  miles south.  You want the distance between you and the epicenter to be at least 80 mi.  You have another right triangle with legs 60 and y + 45 and hypotenuse 80.

[tex](y+45)^2+60^2=80^2\\\\(y+45)^2+3600=6400\\\\(y+45)^2=2800\\\\y+45=\sqrt{2800}\\\\y=\sqrt{2800}-45 \approx 7.91 \rm mi[/tex]

Answer: A. To find the number of glass squares each student will receive, we need to divide the total number of squares by the number of students.

We can write this as:

x = number of glass squares per student

x = 1240 / 121

B. To find the number of squares each student will receive, we need to solve for x by dividing 1240 by 121.

1240 ÷ 121 = 10.246753246753247

C. Each student will get 10 whole glass squares.

D. The remainder in this context is the number of glass squares that cannot be distributed evenly among the students. In this case, the remainder is 30. It means that there will be 30 glass squares left over after each student has received 10 squares. It's like remainder in division where after dividing 1240 by 121 the quotient is 10 and the remainder is 30.

There are a number of tales of how he initially created his scale, but the original publication states that the lower Fahrenheit  defining point, 0 °F, was set as the freezing temperature of a brine solution made from a combination of water, ice, and ammonium chloride (a salt).

Thus, the difference between Celsius and Fahrenheit is 1.8 times. In other words, 1 degree Fahrenheit is equivalent to 5/9 degree Celsius. These two temperature scales overlap at -40 degrees, which means that -40 degrees Fahrenheit is equivalent to -40 degrees Celsius despite their quite significant discrepancies.

°C) is a different unit of measurement for temperature. Except for the United States, most nations use Celsius as their unit of measurement. 0 degrees Celsius is really chilly. 40 degrees is a scorching temperature!

The measure of side KL in the given quadrilateral is 31.88 units.

A quadrilateral is a four-sided polygon with four edges and four corners that is used in geometry.

The Latin words Quadri, a variation of four, and latus, meaning "side," are the source of the name.

A two-dimensional shape with four sides, four vertices, and four angles is referred to as a quadrilateral.

Convex and concave are the two main forms.

Convex quadrilaterals can also be divided into a number of subgroups, including trapezoids, parallelograms, rectangles, rhombus, and squares.

So, according to the given figure of FGHI and JKLM:

FG/JK = GH/KL = HI/LM = FI/JM

GH/KL = HI/LM

7/KL = 9/41

KL = 7*41/9 = 31.888

Ella can type faster than Andrew because the rate at which she types is faster than Andrew's rate by 0.5 text per second.

In Mathematics, rate of change can be defined as a type of function that describes the average rate at which a quantity either decreases or increases with respect to another quantity.

In this scenario, we would determine the rate of change with respect to the amount of words that Andrew and Ella can type per second as a ratio. For the amount of words that Andrew can type per second, we have:

Andrew = 7/21 = 28/84 = 1/3 or 1:3.

For the amount of words that Ella can type per second, we have:

Ella = 4/14 = 16/56 = 1/3.5 or 1:3.5

Difference = 3.5 - 3

Therefore, we can logically conclude that Ella can type faster.

Complete question :

A set of middle school student heights are normally distributed with a mean of 150 centimeters and a standard deviation of 20 centimeters. Darnell is a middle school student with a height of 161.4 centimeters.

What proportion of student heights are lower than Darnell's height?

Answer:

0.716 (71.6%)

Step-by-step explanation:

Given that :

Mean, μ = 150

Standard deviation, σ = 20

Darnell's height, x = 161.4

(x < 161.4)

We obtain the standardized score, then find the proportion using a standard normal distribution ;

Zscore = (x - μ) / σ

Zscore = (161.4 - 150) / 20

Zscore = 11.4 / 20

Z = 0.57

P(Z < 0.57) = 0.71566 (Z probability calculator)

This means that about 0.716 (0.716 * 100% = 71.6%) of student's height are lower than 161.4 centimeters

Answer: 0.11

Step-by-step explanation:

Since we know the distribution of heights is normally distributed, the probability P(X>175)  can be found by calculating the shaded area above X=175  in the corresponding normal distribution:

P(X>175)≈0.11 is the answer.

In  the roulette game, the probability that you get a total of 15 given on the first spin you spin a 2 is 8.26%

To find: the probability that you get a total of 15 in three trials

Given that you spin a 2 on the first trial.

This means, the required probability  is equivalent to the probability of finding a sum of 13 in the next two trials.

In each trial, there are 11 possible outcomes as the pockets numbered from 0 to 10.

so the sample space i.e., the total number of outcomes is:

S = 11^2

S = 121

And the favourable outcomes would be,

(2, 11), (3, 10), (4, 9), (5, 8), (6, 7), (7, 6), (8, 5), (9, 4), (10, 3), (11, 2)

So, the number of favourable outcomes A = 10

Using the definition of probability,

P = A/S

P = 10/121

P = 0.0826

P = 8.26%

What is the radius of the circle?

Any line segment connecting a circle's center to its perimeter is considered a circle's or sphere's radius, and in more recent usage, their length is also considered. The word "radius" is derived from Latin and means "ray" as well as "the spoke of a chariot wheel."

Here, we have

The radius of the circle of oil spread is modeled by the function r = ∛s where s = time in seconds.

The area of the oil spill A = πr²

= π(∛s)²

So, we need to find the area of the oil spill when s = 5.

So, A = π(∛s)²

A = π(∛5)²

A = π(1.7099)²

A = 2.924π square inches.

Hence, the area of the oil spill is 2.924π square inches.
