Answer:

There could be many answers: 2/12, 3/18, 4/24...

Step-by-step explanation:

You never really gave options but all you do is just take 1/6 and multiply the top and bottom by a certain number to get what you're looking for, for example 1/6 times 2, both on the top and bottom will get you 2/12 because 1 times 2 is 2 and, 6 time 2 is 12. :)

The angle of depression from a window 10 m above the ground to a coin on the ground is
15°. Find the distance of the coin from the base of the building.

Answers

Answer:

37.3 m

Step-by-step explanation:

Let the distance of the coin to the base of the building be represented by x. Applying the required trigonometric function, we have:

Tan θ = [tex]\frac{Opposite}{Adjacent}[/tex]

Tan 15 = [tex]\frac{10}{x}[/tex]

0.2680 = [tex]\frac{10}{x}[/tex]

x = [tex]\frac{10}{0.2680}[/tex]

  = 37.3134

x = 37.3 m

The distance of the coin from the base of the building is 37.3 m.

Suppose an upward force of 15 N is added to the box. What will be the net vertical force on the box?

Answers

Answer:

Step-by-step explanation:

Suppose an upward force of 15 N is added to the box. What will be the net vertical force on the box?

THIS IS THE COMPLETE QUESTION BELOW;

1. Explain how you calculate the net force in any direction on the box.

2. Suppose an upward force of 15 N is added to the box. What will be the net vertical force on the box?

3. What force could be applied to the box to make the net force in the horizontal direction zero? Explain.

4. Suppose a force of 25 N to the right is added to the box. What will be the net force to the right?

CHECK THE ATTACHMENT FOR THE FIQURE.

1)since the given horizontal forces are acting on the box at opposite direction then

NET FORCE= (100- 50)N

= 50N( this is because the 100N and 50N acting Horizontally will cancel each other, then the remaining force is 50N.

✓Since, the  two vertical forces also acted on the box in opposite direction, then

NET FORCE= (25 25)N

= 0N

Note: horizontal forces are one acting from right to left and vice versa, while vertical forces are ones acting from up to down and vice versa.

HENCE, NET FORCE = 50N + 0N= 50N

2) since the net vertical force was 0N, if

15N force is added then we still have NET FORCE OF 15N

3) if  force of 50N is applied to horizontal forces moving from left to right then NET HORIZONTAL FORCES= 0N

4) since, the net force for the box is 50N, if  Horizontal force of 25N is added  moving left to right then NET FORCE = 25N for whole box.

A wire attached to the top of a building makes a 15° angle with the ground. If the building is 25 feet high, how

long is the wire?

Answers

Answer:

96.6feet

Step-by-step explanation:

,

From the attachment, we can see that a triangle is formed.

From trigonometry,

Sin(X)= opposite/hypothesis

Where Opposite sides=25feet

Hypotenuse sides= X feet

Sin(15)= 25/X

Cross multiply

Sin(15)= 0.2588

0.2588=25/X

X= 25/0.2588

X=96.6feet

Hence, the wire is 96.6 feet high

B is the midpoint of AC and AC=8r-20,and AB=3x-1
Find BC

Answers

Answer:

BC = 26

Step-by-step explanation:

since B is the midpoint of AC, then AB = BC

AC = 8x - 20 & AB = 3x - 1

AC = AB + BC or 2AB

8x - 20 = 2(3x - 1)

8x - 20 = 6x - 2

subtract 6x form each side

2x - 20 = -2

add 20 to each side

2x - 20 + 20 = -2 + 20

2x = 18

x = 9

BC = 3x - 1

BC = 27 - 1

BC = 26

AC = 52

sin(x)=-0.7

Answers

Answer:

A. [tex]x_{1} = -44.427^{\circ}\pm n\cdot 360^{\circ}[/tex]

B. [tex]x_{2} = -135.573^{\circ}\pm n\cdot 360^{\circ}[/tex]

Step-by-step explanation:

The negative value of the sine function indicates that [tex]x[/tex] is located at third and fourth quadrants. Besides, this function has a period of 360º. There are two families of solutions:

[tex]x_{1} = \sin^{-1} (-0.7)[/tex]

[tex]x_{1} = -44.427^{\circ}\pm n\cdot 360^{\circ}[/tex]

[tex]x_{2} = \sin^{-1} (-0.7)[/tex]

[tex]x_{2} = -135.573^{\circ}\pm n\cdot 360^{\circ}[/tex]

Hence, right answers are A and B.
