you look down at an object on the ground. If your eyes are
55 feet above the ground, and the angle of depression is 50º, how far is the object
from you?


i believe it’s 2,750 feet?

Answers

Answer:

We can think of this as a triangle rectangle.

We know that you eyes are 55ft above the ground, this can be one cathetus.

We also know that you see with an angle of depression of 50°, from this angle, our known cathetus would be the opposite cathetus.

Now we want to know how far is the object from you, this would be the hypotenuse of the triangle rectangle.

So we only know one angle and the opposite cathetus to this angle, then we can use the relation:

Sin(θ) = (opposite cathetus)/(hypotenuse)

Then if we use this equation, we will get:

Sin(50°) = 55ft/hypotenuse

hypotenuse = 55ft/sin(50°) = 71.8 ft

This means that the distance between you and the object is 71.8 ft.

Answer:
a° = 41°
b° = 139°

Explanation:
Vertical angles are opposite angles created by a pair of intersecting lines, and are equal in measure.
Angle a° is a vertical angle with the angle created by D and B.
a° = ∠DB
a° = 41°

Straight lines are 180°.
Line DC is straight and is divided into two angles, which will add to 180°.
b° + 41° = 180°
b° = 180° - 41°
b° = 139°

Answer:

a° = 41°

b° = 139°

Step-by-step explanation:

a° = ∠DB

a° = 41°  

b° + 41° = 180°

b° = 180° - 41°

b° = 139

Ben's Game World is having a sale on video games. The store is offering a sale pack of 4 video games for $43.80. What is the unit price of a video game in the sale pack?

Answers

Answer:

Answer:

a) 10.95

b) 76.65

Step-by-step explanation:

To find the unit price of Ben's video games, divide 43.80 by 4, which is equal to 10.95. So, the unit price is 10.95 at Ben's Game World.

Then, using the unit price we found earlier, multiply 10.95 by 7, which will gives us the cost of 7 games at Roberto's Electronics. You'll get 76.65. So, the cost of 7 games at Roberto's Electronics, using the same unit price at Ben's Game World, would be 76.65.

Write the equation of a parabola in factored form if the x-intercepts are (3,0) and (-5,0) with a maximum point at ( -1,8)

Answers

Answer:

y = - [tex]\frac{1}{2}[/tex] (x - 3)(x + 5)

Step-by-step explanation:

Given the x- intercepts are x = 3 and x = - 5 then the corresponding factors are

(x - 3) and (x + 5)

The equation is the the product of the factors, that is

y = a(x - 3)(x + 5)  ← a is a multiplier

To find a substitute (- 1, 8) into the equation

8 = a(- 1 - 3)(- 1 + 5) = a(- 4)(4) = - 16a ( divide both sides by - 16 )

- [tex]\frac{1}{2}[/tex] = a

Then

y = - [tex]\frac{1}{2}[/tex] (x - 3)(x + 5) ← in factored form

At the football game, 3 hamburgers and 6 soft drinks cost $27, and 3 hamburgers and 3 soft drinks cost $18. Which two equations can be used to determine the price of a hamburger and the price of a soft drink?

Let x represent the cost of a hamburger and y represent the cost of a soft drink.

Answers

Answer:

Let be "x" the cost in dollars of a hamburger and "y" the cost in dollars of a soft drink.

The cost of 4 hamburguers can be represented with this expression:

4x4x

And the cost of 6 soft drinks  can be represented with this expression:

6y6y

Since the total cost for 4 hamburgers and 6 soft drinks is $34, you can write the following equation:

4x+6y=344x+6y=34   [Equation 1]

 The following expression represents the the cost of 3 soft drinks:

3y3y

According to the information given in the exercise, the total cost for 4 hamburgers and 3 soft drinks is $25. Then, the equation that represents this is:

4x+3y=254x+3y=25 [Equation 2]

Therefore, the Equation 1 and the Equation 2 can be used to determine the price of a hamburger and the price of a soft drink

Answer:

3x + 6y = 27

3x + 3y = 18

x = $3, y = $3

Step-by-step explanation:

I will solve by using the elimination method.

3x + 6y = 27

3x + 3y = 18

Subtract top equation by bottom.

3x + 6y = 27

- (3x + 3y = 18)

_____________

  0 +  3y  =  9

3y = 9

y = 3

Plug y in for three

3x + 6*3 = 27

3x + 18 = 27

3x = 9

x = 3

So, your solution is x = $3, y = $3

And in the garden, he whispered Quietly, they said, or we shall wake them.But it wasnt that you woke us. Oh, no.Theyre looking for it; theyre drawing the curtain, one might say, and so read on a page or two. Now theyve found it, one would be certain, stopping the pencil on the margin. And then, tired of reading, one might rise and see for oneself, the house all empty, the doors standing open, only the wood pigeons bubbling with content and the hum of the threshing machine sounding from the farm.What did I come in here for? What did I want to find? My hands were empty. Perhaps its upstairs then? The apples were in the loft. And so down again, the garden still as ever, only the book had slipped into the grass.But they had found it in the drawing room. Not that one could ever see them. The window panes reflected apples, reflected roses; all the leaves were green in the glass. If they moved in the drawing room, the apple only turned its yellow side.Yet, the moment after, if the door was opened, spread about the floor, hung upon the walls, pendant from the ceilingwhat? My hands were empty. The shadow of a thrush crossed the carpet; from the deepest wells of silence the wood pigeon drew its bubble of sound. Safe, safe, safe, the pulse of the house beat softly. The treasure buried; the room . . . the pulse stopped short. Oh, was that the buried treasure? A moment later the light had faded. Out in the garden then? But the trees spun darkness for a wandering beam of sun. So fine, so rare, coolly sunk beneath the surface the beam I sought always burnt behind the glass. Death was the glass; death was between us; coming to the woman first, hundreds of years ago, leaving the house, sealing all the windows; the rooms were darkened. He left it, left her, went North, went East, saw the stars turned in the Southern sky; sought the house, found it dropped beneath the Downs. Safe, safe, safe, the pulse of the house beat gladly. The Treasure yours.The wind roars up the avenue. Trees stoop and bend this way and that. Moonbeams splash and spill wildly in the rain. But the beam of the lamp falls straight from the window.

Sound asleep. Love upon their lips.Stooping, holding their silver lamp above us, long they look and deeply. Long they pause. The wind drives straightly; the flame stoops slightly. Wild beams of moonlight cross both floor and wall, and, meeting, stain the faces bent; the faces pondering; the faces that search the sleepers and seek their hidden joy.Safe, safe, safe, the heart of the house beats proudly. Long years he sighs. Again you found me. Here, she murmurs, sleeping; in the garden reading; laughing, rolling apples in the loft.
