Kyle is at the end of a pier 30 feet above the ocean. His eye level is 3 feet above the pier. He is using binoculars to watch a whale surface. If the angle of depression of the whale is 20(degrees), how far is the whale from kyles biboculars? round to the nearest tenth foot​

Answers

Answer 1

Answer:

96.5 feet. looked it up.

Step-by-step explanation:

Have a great day:)

Answer 2

Answer:

Given: the angle of depression= 20°

Height of Kyle from the ocean = 30 feet

To find: how far is the whale from kyles biboculars?

Step-by-step explanation:

Let the distance between them be y

sin20° = [tex]\frac{33 }{y}[/tex]

=> 0.342 = [tex]\frac{33}{y}[/tex]          [  sin20° = 0.342]

=> y =  33/ 0.342

=> y = 96.5 ft

So, the distance between them is 96.5 ft

what is angle of depression?

The angle of depression is the angle formed by the horizontal line and the horizontal line's observation of the item. When we know the angles and the distance of an object from the ground, it is primarily utilized to find the distance between the two objects. If the line of sight is directed downward from the horizontal line, then an angle is created with the horizontal line.

The angle produced between the horizontal line and the observer's line of sight is known as the angle of depression if the object being observed is below the observer's level. The angle of depression is shown in the image below as.

m ∠ 2 = 19 * 3 = 57°

Step-by-step explanation:

3x + x = 76°

4x = 76°

Divide both sides by 4;

x = 19°

m ∠ 1 = 19°

Question 1 y=(1/4)x+8

Step-by-step explanation:

Use  calculator

Answer:

1) y = 1/4x + 8

2) y = -x - 6

3) y = -2x - 1

4) y = -2/5x -3

5) y = 4x + 9

Step-by-step explanation:

1) y = 1/4x + c

6 = -2 + c

c = 8

y = 1/4x + 8

2) y = -x + c

-7 = -1 + c

c = -6

y = - x - 6

3) y = -2x+c

13 = 14 + c

c = -1

y = -2x - 1

4) 5y = -2x + 15

y = -2/5x + 3

Hence,

y = -2/5x + c

-10 = -2/5 + c

c = -3

Therefore,

y = -2/5x -3

5) Slope: (1-(-11))/(-2-(-5))

= (1+11)/(-2+5)

= 12/3

= 4

y = 4x +c

Substituting any one of the points:

1 = -8 + c

c = 9

y = 4x + 9

What is the sprinter's average speed rounded to 4 sf

Answers

The average speed is 40.176 Km/h.

What is Average speed?

The average speed is the total distance traveled by the object in a particular time interval.

Given:

distance = 100m

time= 8.96 seconds

So,

average speed = distance/time taken

= 100/8.96

= 11.16 m/s

and in Km/h

= 11.16* 18/5

= 40.176 Km/h

Hence, the average speed is 40.176 Km/h.

Answer:  To isolate the variable in ¹/₄ x multiply by 4 or divide by 1

Step-by-step explanation:

              Let                  ¹/₄ x = a

multiply by 4:          4 (¹/₄) x  = 4 a

                                      1  x  = 4 a

divide by 1:                    ¹/₁ x  = ⁴/₁ a

                                          x  = 4a    [x is now isolated]

How to isolate the variable in 1/4x

From the question, we have the following parameters that can be used in our computation:

Expression = 1/4x

To isolate the variable in 1/4x, we multiply by 4

So, we have

Expression = 1/4x * 4
