Identify the angle of depression.

Answers

Answer:

4

Step-by-step explanation:

An angle of elevation is the angle formed by a horizontal line and a line of sight to a point above the line.

An angle of depression is the angle formed by a horizontal line and a line of sight to a point below the line.

∠3 is an angle of elevation because it is formed by the line of sight that is above the horizontal line.

∠4 is an angle of depression because it is formed by the line of sight that is below the horizontal line.

∠5 is neither an angle of depression nor an angle of elevation because it is not formed by the horizontal line and the line of sight.

∠6  is an angle of elevation because it is formed by the line of sight that is above the horizontal line.

Therefore, the angle of depression is ∠4.

Which transformations could have been used to create A'B'C'? Choose all that apply.
a 180° rotation about the origin and then a translation 3 units up and 1 unit left
a translation 3 units up and 1 unit left and then a 180° rotation about the origin
a 90 degree clockwise rotation about the origin and then a reflection over the Y axis
a 90° counterclockwise rotation about the origin and then a reflection over the X axis
A translation through you to down and one unit right and then I 108° rotation about the origin

Answers

The correct transformation is a rotation of 180° around the origin followed by a translation of 3 units up and 1 unit to the left.

Which transformation is used to get A'B'C'?

To analyze this we can only follow one of the vertices of the triangle.

Let's follow A.

A starts at (3, 4). If we apply a rotation of 180° about the origin, we end up in the third quadrant in the coordinates:

(-3, -4)

Now if you look at A', you can see that the coordinates are:

A' = (-4, -1)

To go from (-3, -4) to (-4, -1), we move one unit to the left and 3 units up.

Then the complete transformation is:

A rotation of 180° around the origin, followed by a translation of 3 units up and 1 unit to the left.

Step-by-step explanation:

There is 12 inches in a foot, and if he needs twice the amount he already has which is 4 then you would multiply 0.05 times 24 and you would get $1.2

Answer: $1.20 for 2 feet of balsa wood

Step-by-step explanation: There are 12 inches in 1 foot, and 24 inches in 2 feet. The cost per inch is 0.05, multiplying 24 (inches) x 0.05 (the cost per inch) would equal $1.20

Step-by-step explanation:

You want to know the total output (real gdp) of 1000 workers, each working 2500 hours producing real output of $20 per hour.

GDP

The output, called "gross domestic product" or GDP, is the total output of all workers for the hours they work:

  (1000 worker) × (2500 hours/worker) × ($20/hour) = $50,000,000

The GDP will be $50,000,000 or 50 million dollars.

By applying one of the laws of logarithm, we get

[tex]64 = 4^{y}[/tex]

Now, express 64 in index form,

[tex]4^{3} = 4^{y}[/tex]

Since the bases are equal, we can equal the powers to get

Answer:

Step-by-step explanation:

1. the chance of getting soup is 1/3, the chance of getting a burger is 1/2, and the chance of getting coke is 1/2, multiply these chances to get (1/3) *(1/2) * (1/2) = 1/12

2. the chance of getting fries is 1/3, the chance of getting a burger is 1/2, and the chance of getting any drink is 1, multiply these chances to get (1/3) * (1/2) * 1 = 1/6

Q9

x = 200° (arc measure = central angle measure)The inscribed angle y is half of the arc length xy = 1/2xy = 1/2(200°)y = 100°

Q10

x + 112 = 180x = 68°y + 81 = 180y = 99°

Answer:

9.  x = 200  and  y = 100

10.  x = 68  and  y = 99

Step-by-step explanation:

Question 9

The measure of an arc is the measure of its central angle.

⇒ x = 200

This is a non-cyclic quadrilateral as not all its vertices touch the circumference of the circle.

The angle at the center is twice the angle at the circumference.

⇒ y = 200 ÷ 2

⇒ y = 100

Question 10

This is a cyclic quadrilateral as all its vertices touch the circumference of the circle.  

The opposite angles in a cyclic quadrilateral add up to 180°.

⇒ x + 112 = 180

⇒ x = 68

⇒ y + 81 = 180

⇒ y = 99
