If sin B = − 1/3 with B in QIII, find the following.
cos B/2
Answer:
In the third quadrant, the sine of an angle is negative, so the angle itself must be between 180 and 270 degrees. This means that the cosine of the angle, and therefore the cosine of half the angle, is also negative.
To find the exact value of the cosine of half the angle, we can use the double angle formula for cosine, which states that cos(2A) = 1 - 2sin^2(A). Since the sine of half the angle is sin(B/2) = sqrt((1 - cos(B))/2), we can plug this into the double angle formula to get:
cos(B/2) = sqrt(1 - cos(B))/sqrt(2) = sqrt((1 - (-1/3))/2) = sqrt(4/6)/sqrt(2) = sqrt(2/3)/sqrt(2) = sqrt(1/3)
Therefore, the value of cos(B/2) is sqrt(1/3), which is positive because B/2 is between 0 and 90 degrees. The exact value of the cosine of half the angle B in the third quadrant is sqrt(1/3).

Step-by-step explanation:
Mojo Mining has a bond outstanding that sells for $2,120 and matures in 18 years. The bond pays semiannual coupons and has
a coupon rate of 6.66 percent. The par value is $2,000. If the company's tax rate is 25 percent, what is the aftertax cost of debt?
4.95%
6.24%
O 5.82%
O 4.32%
O 4.68%
4
The aftertax cost of debt to Mojo Mining, given the company tax rate, and the maturity term of the bond, is F. 4. 58 %
How to find the aftertax cost of debt ?First, find the yield on the bond. This yield can be found by the Rate function on Spreadsheet.
N = 18 years x 2 = 36 semi annual periods
PMT = 6.66% / 2 x 2, 000 = $ 66. 60
PV = 2, 120
FV = 2, 000
The spreadsheet would show a result of 3.05 % per semi annum. The annual rate is therefore:
= 3.05 % x 2
= 6.10 %
The aftertax cost of debt to Mojo Mining is therefore:
= 6.10 % x ( 1 - 25 % tax rate )
= 4.68%

F- distribution is used to reject the null hypothesis when the two samples have the same variance.
Here, the null hypothesis of equal coefficients has to be rejected in a global test.

Lines n and o are parallel and are cut by the transversal p.
What is the measure of ∠m ?
A. 23°
B. 33°
C. 67°
D. 157°
Using the Corresponding Angle Theorem, ∠m = 23 degree. So, the option A is correct.
In the given question, lines n and o are parallel and are cut by the transversal p.
We have to find the measure of ∠m and choose the correct option.
As we know that;
When two parallel lines are intersected by another line, corresponding angles are the angles that are formed in matching corners or corresponding corners with the transversal.
So using the Corresponding Angle Theorem
∠m = 23 degree
Hence, the option A is correct.

Jump up! Refer to Exercise 6. Suppose that the corrected long-jump distances are converted from centimeters to meters (note that 100 cm = 1 m). (a) What shape would the resulting distribution have? Explain your answer. (b) Find the mean of the distribution of corrected long-jump distance in meters. (c) Find the standard deviation of the distribution of corrected long-jump distance in meters.
Shape would the resulting distribution have very symmetric distribution with a single peak was found to be the corrected long-jump distances in centimeters distribution's shape.
Define symmetry.In common parlance, the term "symmetry" describes a sense of lovely proportion and balance. A more exact meaning of "symmetry" can be found in mathematics, where it typically refers to an object that is unaffected by certain transformations like translation, reflection, rotation, or scaling.
Given,
100 cm = 1 m
Xₙ = 557.3 cm
Divide each centimeter number by 100 to convert the corrected long jump distances from centimeters to meters.
A very symmetric distribution with a single peak was found to be the corrected long-jump distances in centimeters distribution's shape.
The distribution's structure is unaltered when each value in the data is divided by 100 since there are no changes to the relationships between any two pieces of data.
Since there is just one peak in this example, the corrected long-jump distances in meters distribution likewise has an almost symmetric form.

Answer:
3. y int= 6
4. m=6
5. y=-2x-8
Step-by-step explanation:
3. since the y intercept is when x=0 the table shows the y=6.
4. to find m we use change in y/change in x
the change in y is 6 because 6-0=6
change is x is 1 because 0--1=1
6/1=6
5. y=mx+c
c is y intercept thus c= -8
m is function rate/ gradient of the line = -2
this is because:
change in y= -8--2=-6
change in x= 0--3=3
-6/3= -2
thus y=-2x-8

Answer:
120º
Step-by-step explanation:
This might be the correct answer if I'm not mistaken:
Extending the right side of the bottom triangle leads to m<1 and 120 vertical angles.
You use the Vertical Angles Theorem, and figure that 120 is congruent to m<1. Thus, i think 120 degrees is the answer.
The hypotenuse of a right triangle is 13 ft long. The shorter leg is 7 ft shorter than the longer leg. Find the side lengths of the triangle.
Answer:
Since the length of a side of a triangle must be a positive number, the only solution that makes sense is $x = \frac{14 + \sqrt{-764}}{8}$. The length of the shorter leg is then $y = x - 7 = \frac{14 + \sqrt{-764}}{8} - 7 = \frac{7 + \sqrt{-764}}{8}$.
Therefore, the side lengths of the triangle are $\frac{7 + \sqrt{-764}}{8}$ and $\frac{14 + \sqrt{-764}}{8}$.

You accept a job with a salary of $37,300. After 6 months, you receive a 6% raise. What is your new salary?
Answer:
If you accept a job with a salary of $37,300 and receive a 6% raise after 6 months, your new salary will be $37,300 x 6/100 = $2,238. This is the amount of your raise. To determine your new salary, we can add the raise to your original salary, which gives us:
New salary = $37,300 + $2,238 = $39,538
Therefore, your new salary after receiving a 6% raise will be $39,538.
