Corresponding Angles

Step-by-step explanation:

Use the Law of Cosines to determine the indicated angle 0. (Assume a - 139.5, b = 59.5, and c = 156.5. Round your answer to the nearest degree.)

Answers

Answer:  approximately 95 degrees

====================================================

Work Shown:

Law of cosines

c^2 = a^2 + b^2 - 2*a*b*cos(C)

156.5^2 = 139.5^2 + 59.5^2 - 2*139.5*59.5*cos(C)

24492.25 = 19460.25 + 3540.25 - 16600.5*cos(C)

24492.25 = 23000.5 - 16600.5*cos(C)

24492.25 - 23000.5  = -16600.5*cos(C)

1491.75  = -16600.5*cos(C)

-16600.5*cos(C) = 1491.75

cos(C) = (1491.75)/(-16600.5)

cos(C) = -0.0898617511520737

C = arccos(-0.0898617511520737)

C = 95.1556537886261

C = 95 degrees approximately

Make sure your calculator is in degree mode.

"arccos" is short for "arccosine" which is the same as inverse cosine. Your calculator may show this as the button labeled [tex]\cos^{-1}[/tex]

A while ago, Nicole bought shares of stock in a high-tech firm. At that time, the selling price was $60 per share. According to today's newspaper, a share is currently worth 30% more. What is the current value of one share?

Answers

Answer:

Step-by-step explanation:

1. Dividends

2. Capital gains

-The discounted present value of the sum of next period's dividend plus next period's stock price

-The discounted present value of all future dividends

P0 = [(Div1)/(1+R)] + [P1/(1+R)]

where Div 1 = expected dividend paid at year's end

P1 = expected price at year's end

R = discount rate

Answer:

$78

Step-by-step explanation:

A share is worth 30% more, so multiply 30% by 60 to get 30% of 60, which is 18. Then, add 18 to 60 because the share is 30% more, and you get 78.

During the regular season, a National Basketball Association team plays 82 games and a National Football League team plays 16 games. In simplest form, what is the ratio of NFL regular season games to NBA regular season games?

Answers

Answer:

NFL teams play 16 regular season games each year, NHL and NBA teams play 82, while MLB teams play 162-could invalidate direct comparisons of win percentages alone. As an example, the highest annual team winning percentage is roughly 87% in the NFL but only 61% in MLB and part (but not all) of that difference is undoubtedly tied to the shorter NFL regular season

please add me as buddy

Answer:

a = 3 inches

b = 3[tex]\sqrt{3}[/tex] inches

Step-by-step explanation:

From the figure,

Sin 30° = Opposite / Hypotenuse

Sin 30° = a / 6

1 / 2 = a / 6         (Sin 30° = 1/2)

a = 3 inches

From the same angle,

Cos 30°  = Adjacent / Hypotenuse

Cos 30° =  b / 6

[tex]\frac{\sqrt{3} }{2}[/tex] = [tex]\frac{b}{6}[/tex]              (Cos 30° = [tex]\sqrt{3}[/tex] / 2)

b = 6 * [tex]\frac{\sqrt{3} }{2}[/tex]

b = 3[tex]\sqrt{3}[/tex] inches

Find the value that completes the ordered pair to describe the transformation of f(x) to g (x).

If (x, y) is a point on f(x), then

(x +
3
, y +
1
) is a point on g(x).

Answers

Answer:

we know that if: (x, y) is a point of f(x):

This means that f(x) = y.

Then (x + 3, y + 1) is a point of g(x)

This means that:

g(x + 3) = y + 1

Then we have two shifts.

For a real and positive number A.

A horizontal shift of A units to the right can be written as:

f(x - A)

A vertical shift of A units up can be written as:

f(x) + A.

Then in this case we have:

An horiozontal shift of 3 units to the right, and a vertical shift of 1 unit up, this means that:

g(x') = f(x' - 3) + 1.

then evaluating this at x' = x + 3

g(x + 3) = f(x + 3 - 3) + 1 = f(x) + 1 = y + 1

That is what we had initially.

Answer:

(x +   2, y +  -2) is a point on g(x).

An object is traveling in a steady speed of 10 1/5 mi/h. How long will it take the object to travel 4 4/5 mi? First round to the nearest integer. Then find the exact answer.

Answers

Answer:

30

Step-by-step explanation:

Speed is the rate of change of distance over time

It will take the object 28 minutes to travel a distance of [tex]\mathbf{4 \frac 45 miles}[/tex]

The given parameters are:

[tex]\mathbf{Speed = 10 \frac 15 mi/h}[/tex]

[tex]\mathbf{Distance = 4 \frac 45 mi}[/tex]

The speed of an object is:

[tex]\mathbf{Speed = \frac{Distance}{Time}}[/tex]

Make Time the subject

[tex]\mathbf{Time= \frac{Distance}{Speed }}[/tex]

Substitute known values

[tex]\mathbf{Time = 4 \frac 45 mi \div 10\frac 15 mi/h}[/tex]

Cancel out the units

[tex]\mathbf{Time = 4 \frac 45 \div 10\frac 15 \ h}[/tex]

Convert fractions

[tex]\mathbf{Time = \frac {24}5 \div \frac{51}5 \ h}[/tex]

Express as multiplication

[tex]\mathbf{Time = \frac {24}5 \times \frac{5}{51} \ h}[/tex]

[tex]\mathbf{Time = \frac {24}{51} \ h}[/tex]

Convert to minutes

[tex]\mathbf{Time = \frac {24}{51} \times 60\ min}[/tex]

[tex]\mathbf{Time = \frac {1440}{51} \ min}[/tex]

[tex]\mathbf{Time = 28 min}[/tex]

Hence, it will take the object 28 minutes

Given: △ABC, CM⊥ AB, BC = 5, AB = 7
CA = 4 sqrt(2)
Find: CM

Answers

Answer:

The general plan is to find BM and from that CM. You need 2 equations to do that.

Step One

Set up the two equations.

(7 - BM)^2 + CM^2 = (4*sqrt(2) ) ^ 2 = 32

BM^2 + CM^2 = 5^2 = 25

Step Two

Subtract the two equations.

(7 - BM)^2 + CM^2  = 32

BM^2 + CM^2         = 25

(7 - BM)^2 - BM^2 = 7               (3)

Step three

Expand the left side of the new equation labeled (3)

49 - 14BM + BM^2 - BM^2 = 7    

Step 4

Simplify And Solve

49 - 14BM = 7              Subtract 49 from both sides.

-49 - 14BM = 7 - 49

- 14BM = - 42              Divide by - 14

BM = -42 / - 14

BM = 3

Step  Five

Find CM

CM^2 + BM^2 = 5^2

CM^2 + 3^2 = 5^2        Subtract 3^2 from both sides.

CM^2 = 25 - 9            

CM^2 = 16                     Take the square root of both sides.        

sqrt(CM^2) = sqrt(16)

CM = 4    < Answer
