Today: Friday, 06 November 2020

Hour: 19.17 WIB (Indonesia)

_______________________________

2 (w + 3) = -2(w - 21)

2w + 6 = -2w + 42

2w + 2w = -6 + 42

4w = 36

w = 9

A park is showing a movie on the lawn. The base of the screen is 6 feet off the ground and the screen is 22 feet high (see figure).

Answers

Answer:

A. 61.82°;

15.64°

B. 33.37°

Step-by-step explanation:

A.

✍️Angle of elevation from 15 ft:

A right triangle is formed. Apply trigonometric ratios formula to find the angle of elevation from 15 ft.

Thus,

Length of the side Opposite to reference angle = 22 + 6 = 28 ft

Adjacent length = 15 ft

Thus, we would have:

[tex] tan(\theta) = \frac{opp}{adjacent} = \frac{28}{15} [/tex]

[tex] tan(\theta) = 1.8667 [/tex]

[tex] \theta = tan^{-1}(1.8667) [/tex]

[tex] \theta = 61.82 [/tex] (2 d.p)

✍️Angle of elevation from 100 ft:

Thus,

Length of the side Opposite to reference angle = 22 + 6 = 28 ft

Adjacent length = 100 ft

Thus, we would have:

[tex] tan(\theta) = \frac{opp}{adjacent} = \frac{28}{100} [/tex]

[tex] tan(\theta) = 0.28 [/tex]

[tex] \theta = tan^{-1}(0.28) [/tex]

[tex] \theta = 15.64 [/tex] (2 d.p)

B.

✍️Distance you'd be from the screen if you lie on the ground and make an angle of elevation of 40° to the top of the screen:

Adjacent length = your distance from the screen = x

Opposite length = 22 + 6 = 28 ft

Angle of elevation = 40°

Tge trigonometric ratios formula to use would be:

[tex] tan(\theta) = \frac{opp}{adjacent} [/tex]

Plug in the values

[tex] tan(40) = \frac{28}{x} [/tex]

Multiply both sides by x

[tex] x*tan(40) = 28 [/tex]

Divide both sides by tan(40)

[tex] x = \frac{28}{tan(40)} [/tex]

[tex] x = 33.37 [/tex] (2 d.p)

The amount of paper that the copy shop used this month was a 25% increase of the amount of paper they used last month. What percent represents the amount of paper used this month? *

Answers

Answer:

You didn't include any image here, but numerically, the amount of paper consumed this month is 125% compared to last month.

If last month's consumption is represented by 4 equal shapes, then the current month's consumption will be 5 shapes.  

If last month's consumption is represented by 8 equal shapes, then the current month's consumption will be 10 shapes.

solve system of equations algebraically​

Answers

Answer:

y=-2 x=-2

Step-by-step explanation:

y=-x-4

y=x

you can plug y in for x in the first equation by using substitution

y=-y-4

and then you solve for y

2y=-4

y=-2

so y equals -2. Since y=x, x also equals -2. Therefore

y=-2 x=-2

Maya is going to an amusement park. The price of admission into the park is $10, and once she is inside the park, she will have to pay $2 for every ride she rides on. How much money would Maya have to pay in total if she goes on 15 rides? How much would she have to pay if she goes on rr rides?

cost for r rides
cost for 15 rides

Answers

Answer:

The cost of r rides = 2r + 10

The cost of 15 rides = $40

Step-by-step explanation:

The form of the linear equation is y = m x + b, where

m is the rate of changeb is the initial amount

Assume that the cost of r rides is c

∵ The number of the ride is r

x = r

∵ The cost of r rides is c

y = c

∵ The price of admission into the park is $10 ⇒ initial amount

b = 10

∵ She will have to pay $2 for every ride ⇒ rate of change

m = 2

→ Substitute them in the form of the equation above

c = 2r + 10

The cost of r rides = 2r + 10

∵ She goes on 15 rides

r = 15

→ Substitute it in the form of the equation

∵ c = 2(15) + 10

∴ c = 30 + 10

c = 40

The cost of 15 rides = $40

Joseph’s lunch at a restaurant costs $13.00, without tax. He leaves the waiter a tip of 17% of the cost of the lunch, without tax. What is the total cost of the lunch, including the tip without tax? *

Answers

Answer:

17% of 13 is 2.21

13 + 2.21 = 15.21

Step-by-step explanation:

Joseph's lunch costs = $13 without taxes

He leaves tip for the waiter = 17% of cost of the lunch

= 17% of $13

= 13 ×  

= ( 13 × 0.17)

= $2.21

Total cost of lunch + tip = 13 + 2.21

                                      = $15.21

What is the correct order of the steps used to derive the identity?

B.) 4, 5, 3, 1, 2,
C.) 3, 4, 5, 1, 2
D.) 3, 4, 1, 5, 2

Answers

The correct order of the steps used to derive the identity is (A.) 4, 3, 5, 1, 2

How to determine the correct order of step?

The trigonometry identity is given as:

tan(2x)

When the tangent formula is applied, we have:

[tex]\tan(2x) = \frac{\sin(2x)}{\cos(2x)}[/tex] --- step 4

Expand sin(2x) and cos(2x)

[tex]\tan(2x) = \frac{2\sin(x)\cos(x)}{\cos^(x) - \sin^2(x)}[/tex] --- step 3

The option from the list that obey the above order is (a) 4, 3, 5, 1, 2

Hence, the correct order of the steps used to derive the identity is (A.) 4, 3, 5, 1, 2

Find the value of x. Then find the measure of each labeled angle

Answers

Answer:

x = 109

Top Right Angle = 109

Bottom Right Angle = 71

Step-by-step explanation:

Notice the two right angles on the left and recognize that the figure is a a quadrilateral (4 sides). That means it adds up to a total of 360 degrees.

(x-38) + x + 90 + 90 = 360

2x + 142 = 360

2x = 218

x = 109

(x - 38) = (109 - 38)

71 degrees for bottom right angle

109 for top right angle

Answer:

Yo, the slope of the line is 6 yo!

Step-by-step explanation:

You see, to find the slope of 2 points, Here's what ya do little fella: Pick any y-coordinate point(-2) or (-8). When you do, subtract -2 and -8 so in this case,      -y - (-x) = -y + x. So, when done correctly, you get 6 because -2 - (-8) is equal to -2 + 8. Ya go to the x-coordinate. If you subtracted -8 from -2, you have to subtract 4 from 5. If you also subtracted -2 from 8, you have to subtract 5 from 4. So, it has to be in order. 5 - 4 = 1. So then, you divide your answer 6/1 = 6. So 6 is the slope people.
