Answer 1

Answer:

B

Step-by-step explanation:

I love these!  Ok, the expanded formula you need for this is

[tex]6(cos\frac{5\pi }{6}+sin\frac{5\pi }{6}i)[/tex]

From the unit circle we get the cos and sin of that angle and fill them in:

[tex]6(-\frac{\sqrt{3} }{2}+\frac{1}{2}i)[/tex]

Distributing through the parenthesis gives you

[tex]-\frac{6\sqrt{3} }{2}+\frac{6}{2}i[/tex]

which simplifies to

[tex]-3\sqrt{3}+3i[/tex]

Answer 2
Final answer:

To convert 6cis (5pi)/6 from polar form to rectangular form, use the formula r*cos(theta) + r*sin(theta)*i. The magnitude (r) is 6 and the angle (theta) is 5pi/6. The rectangular form results to be B. -3 Square root of 3 +3i.

Explanation:

The student is asked to convert the complex number 6cis (5pi)/6 from polar form to rectangle form. In polar form, a complex number can be represented as rcis(theta), where r is the magnitude and theta is the angle. To convert this to rectangular form, we use the formula r*cos(theta) + r*sin(theta)*i. In this case, r=6 and theta=5pi/6. Therefore, the rectangular form of the given number is (6*cos(5pi/6)) + (6*sin(5pi/6))*i which equals -3 +

3 square root

of 3*i. Hence, the correct answer is B. -3 Square root of 3 +3i.

dion flips a coin 20 times and records if it comes up heads. if getting heads is a success, what is the probability of a success on each roll?

Answers

Answer:

[tex]\frac{1}{2}[/tex]

Step-by-step explanation:

The probability of success (getting heads) on one roll DOESNT affect other rolls, so we need to find probability of getting a head in a roll.

Probability is defined as the number of favorable outcomes divided by the total number of outcomes.

Here, favorable outcome is getting a head. So, on one roll, getting a head is 1. Also, the total number of outcomes is either a head or a tail. So total number of outcomes is 2.

Thus,

P(Heads) = 1/2

What is the midpoint of the segment show below

Answers

Answer:

Your answer is B. (3, 5/2)

Step-by-step explanation:

The formula to find the midpoint of a segment is

(x1 + x2) / 2 to find the x value

and (y1 + y2) / 2 to find the y value of the midpoint.

To find the midpoint of the segment in the photo, you would do...

-1 + 3 divided by 2, giving you 3 for your x

and then 2+3 divided by 2, giving you 5/2 for your y.

Hope this helps!

Answer:

B

Step-by-step explanation:

the midpoint is based on the average of the two pair of point X1 and X2 as Y1 and Y1 divided by 2, each one. So, if we settle X1 and Y1 as (-1,2) and X2 and Y1 as (7,3)

(X1 + X2)/2 = (-1+7)/2 = 6/2= 3

(Y1 + Y2)/2 = (2+3)/2 = 5/2

so, we get the Answer B (3 , 5/2)

The following graph shows the amount of snow that fell in Denver, Colorado in the winter of 1888-1889. How many inches of snow did Denver receive during this period?



21 inches
21.3 inches
21.7 inches
22 inches

Answers

Hello!

The answer is:

The second option, Denver received 21.3 inches of snow during the period from 1888 to 1889.

Why?

To know how many inches of snow did Denver receive, we need to sum each the number of inches received per year from 1888 to 1889.

So, from the graph, we have:

For Nov '88, 3 inches.

For Dec '88, 0.8 inches.

For Jan '89, 5.5 inches.

For Feb '89, 8.4 inches.

For Mar '89, 3.6 inches.

Now, adding the number of inches for each month/year, we have:

[tex]Total=3in+0.8in+5.5in+8.4in+3.6in=21.3inches[/tex]

Hence, we have that Denver received a total of 21.3 inches for the 1888-1889 year period.

if a right circular cone is intersected by a plane that passes through only one nappe of the cone but is not parallel to an edge of the cone, as the picture below, what shape is produced?

Answers

Answer:

C. An ellipse

Step-by-step explanation:

If you cut a cone on the side with an angle that will produce an ellipse-shaped plane.

if you were to cut the cone perpendicularly to its height (as if the double cone on the picture was straight up), you would get a circle as the plane, because it would be a transversal cut of a circular cone.

If you cut it with an angle, you're stretching the circle... so you'll have an ellipse.

It is NOT a parabola NOR a hyperbola, since both would require the cross-section to go through the base... which it does not in this problem.  Please refer to the image below.

what is the y coordinate in the solution for the system of linear equations below



-3x+2y=6
and 4x-y=2

please show work :)

Answers

Answer:

y=6

Step-by-step explanation:

use elimination by making the ys opposite in value and eliminating them from the equation so there is only variable:

-3x+2y=6

2(4x-y=2)

-3x+2y=6

8x-2y=4

Combine like terms and divide by 5 on both sides.

5x=10

x=2

Plug x in to find y:

4(2)-y=2

8-y=2

y=6

The y-coordinate in the system of equations, we can use the elimination method. After manipulating the equations, we find that the y-coordinate of the solution is 6.

The y-coordinate of the solution for the given system of linear equations:

-3x + 2y = 6

4x - y = 2

We can use the method of substitution or elimination. Let's use elimination for this example:

Multiply the second equation by 2 to make the coefficients of y equal but opposite: -3x + 2y = 6 becomes -3x + 2y = 6 (unchanged) and 4x - y = 2 becomes 8x - 2y = 4.

Add the modified equations together: (-3x + 2y) + (8x - 2y) = 6 + 4, which simplifies to 5x = 10.

Divide by 5 to solve for x: x = 10 / 5, so x = 2.

Substitute x = 2 into one of the original equations to find y: -3(2) + 2y = 6, which simplifies to -6 + 2y = 6.

Add 6 to both sides to isolate 2y: 2y = 12.

Divide by 2 to solve for y: y = 12 / 2, so y = 6.

Therefore, the y-coordinate of the solution is 6.

Step-by-step explanation:If sin Θ is positive and tan Θ is negative, then the angle should be in the second quadrant using the rule of thumb. In this case, cos Θ is expected to be negative.

Answer:

cos Ф = adj / hyp = √5 / 3

Step-by-step explanation:

If sin Ф is +, then Ф must be in either Quadrant 1 or Quadrant 2.

If tan Ф < 0, then Ф must be in either Quadrant 2 or Quadrant 3.  

So we conclude that Ф is in Quadrant 2.

If sin Ф = opp / hyp = 2/3, then opp = 2 and hyp = 3, and adj is found using the Pythagorean Theorem:

adj = √( 3² - 2² ) = √( 5 )

With adj = √5 and hyp = 3, cos Ф = adj / hyp = √5 / 3

Two sides of a triangle have measures of 6 inches and 12 inches. Which measure could be the length of the third side?

Answers

Final answer:

The third side of a triangle with sides of 6 inches and 12 inches must be greater than 6 inches and less than 18 inches in length, without being exactly 6 or 18 inches.

Explanation:

The length of the third side of a triangle with two sides measuring 6 inches and 12 inches must adhere to the Triangle Inequality Theorem. This theorem states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side. Consequently, for the given triangle, the possible range for the length of the third side, denoted as x, is between 6 inches and 18 inches (exclusive), that is: 12 - 6 < x < 12 + 6. The value of x cannot be exactly 6 or 18 inches because the triangle would collapse into a straight line. Therefore, the permissible length can be any real number greater than 6 inches but less than 18 inches.

d= 157.5 when t is 2.25. all you need to do is plug in 2.25 for t which gives us: d=70(2.25) = 157.7

Final answer:

Multiply the rate, 70 miles per hour, by the given time, 2.25 hours, to find that the distance d is 157.5 miles when t is 2.25 hours.

Explanation:

The question asks for the value of d when t is 2.25 in the equation d = 70t, where d represents the distance in miles and t represents the time in hours. To find the value of d, simply multiply the rate (70 miles per hour) by the given time (2.25 hours).

Answers

Answer:

Your answer is A,B,AND D

Step-by-step explanation:

The standard deviation for a sample of test scores is 0 tells you that, B) all the test scores must be the same value.

What is Standard Deviation?

Standard deviation is a measure in statistics which describes how much is each quantity given deviates from the mean of the whole population.

When a sample of test scores are having a standard deviation of 0, this tells you that, the deviation of each of the values from the mean is 0.

This means that all the values must have the same value.

Suppose the data set is, 1, 1, 1, 1, 1.

All the data points are same.

Mean = 1

Deviation of each of the point from mean = 0

So standard deviation = 0

All the test scores are 0 is a special case of the above case where all the test scores are same.

Hence option B is correct.
