Step-by-step explanation:

CHECK THE ATTACHMENT FOR THE FIQURE

From, trigonometry

tan(θ) = opposite/ adjacent

✓The helicopter is 665 feet from ground.

✓Distance of the helicopter and the line of sight of the girl will be the OPPOSITE SIDE, which is

(665ft - 5 ft)

= 600 ft

✓ from the figure, we can see the distance on the Horizontal side which is the ADJACENT SIDE as ( 280 ft)

✓angle of depression can be calculated as

tan(θ) = opposite/ adjacent

tan(θ)= (660/280)

tan(θ)= 2.357

tan-1=(2.357)

θ= 67°

Hence, angle of depression is 67°

Answer:

(13, 16)

Step-by-step explanation:

Point A has coordinates (3,2) Point b has the coordinates (27,30)

Therefore the width of the diagram = 27 - 3 = 24 units and the height of the diagram = 30 - 2 = 28 unit

The length of the square = 28 unit / 4 square = 7 unit

Also, half of the height of the diagram = 28/2 = 14 unit

Therefore the x coordinate is given by:

27 - (2 × 7) = 27 - 14 = 13 or 27 - 14 (=13) or 3 + 7 + (24 - 3 × 7) = 13

Also, the y coordinate is given by:

30 - (2 × 7) = 30 - 14 = 16 or 30 - 14 (=16) or (30 + 2)÷2 = 16

Therefore the coordinate for point C is given by (13, 16)

Step-by-step explanation:

Answer:

Step-by-step explanation:

y=2x²-6x+3

y=2x+3

2x²-6x+3=2x+3

2x²-6x+3-2x-3=0

2x²-8x=0

2x(x-4)=0

x=0,4

y=0+3=3

and y=2(4)+3=11

so solutions are (0,3) and (4,11)

Answer:

1134.9 ft

Step-by-step explanation:

CHECK THE ATTACHMENT FOR THE FIQURE

From, trigonometry,

Tan(X) = opposite/ adjacent

Distance from the spotlight = 1217 ft, which is the adjacent sides

Let the height of the cloud= X

, Which is the opposite sides

Then substitute, we have

Tan(43°)= X/1217

(0.9325)= X/1217

X= 0.9325×1217

= 1134.9 ft

Hence, the height of the cloud base to the cloud base to the nearest foot is 1134.9 ft

y = -3x-6

x + 3y = 6

3y = -x +6

y = -1/3x +2

-3x-6 = -1/3x +2

-8/3x = 8

x = - 3

y=-3(-3)-6

y = 9-6

y = 3

Answer:

I think the answer is B

Step-by-step explanation:

Answer:

$8

Step-by-step explanation:

I got my answer of $8 because I knew that the total amount of money she was charged for late fees was $24, and she was charged for 3 late fees. Then, I did $24 divided by 3 late fees and got $8 per late fee as my answer.

24 divided by 3 equals 8.

Answer:

a = -7/17

Step-by-step explanation:

Add -4a to -2a

This makes -6a. Then you add 6a to the left to cancel it out, but you must also add 6a to the right of the =

Then you have -7 = 17a

Divide 17 from both sides and you have -7/17 = a

Answer:

y = 6x

Step-by-step explanation:

Equation representing the relation between duration of work and earning is,

y = kx

Here, y = earnings

x = Working hours

k = Proportionality constant

By substituting the values in the given equation,

x = 25 hours

y = $150

150 = k(25)

k = 6

Therefore, equation modeling the situation will be,

y = 6x
