A shark spotter is standing at lookout point 25m above the waters edge. He spots a shark in the water at an angle of depression of 50. If the swimmer that is also in the water is sim from the foot of the lookout spot, how far is the shark from the swimmer?

Answers

Answer 1

The shark is 29.78 from the swimmer.

What is angle of depression?

Angle of depression is the angle between the line of sight and the vertical or perpendicular to the earth surface.

Analysis:

The height of the lookout, the distance of shark from swimmer and line of sight form a right angle triangle.

So that, tan 50 = distance of shark from swimmer/25

Distance of swimmer = 25 tan 50

Distance of swimmer from shark = 25(1.1910 = 29.78m

In conclusion, the distance of the shark from the swimmer is 29.78m

Answer 2

The distance of the shark from the swimmer is 21m

Trigonometry

From the question, we are to determine the distance the shark is from the swimmer

In the diagram,

S is the position of the shark

M is where the shark spotter is standing

and B is the position of the swimmer

The distance between the shark and the swimmer is /BS/

Using SOH CAH TOA

[tex]tan 50^\circ = \frac{25}{/BS/}[/tex]

[tex]1.19175 = \frac{25}{/BS/}[/tex]

∴ [tex]/BS/ = \frac{25}{1.19175}[/tex]

/BS/ = 20.97755

/BS/ ≅ 21 m

Hence, the distance of the shark from the swimmer is 21m.

Given that 5 cos (x+8.5)° - 1 = 0
0° ≤x≤ 90, calculate correct to the nearest degree, the value of x.

Answers

Answer:

x = 70

Step-by-step explanation:

To solve for x, use inverse operations to undo the operations performed on x.

5cos(x +8.5)° -1 = 0 . . . . given

5cos(x +8.5)° = 1 . . . . . . add 1

cos(x +8.5)° = 1/5 . . . . . divide by 5

x° +8.5° = arccos(1/5) . . . . take the inverse cosine

x° = arccos(1/5) -8.5° ≈ 70° . . . . evaluate the expression

The value of x is 70.

If B is 60% more than A, then A is
A. 37.5% less than B.
B. 37.5% of B
C. 60% less than B
D. 60% of B

Answers

Answer:

37.5% less than B

Step-by-step explanation:

It is given that B is 60% more than A.

A (160%) = BA = B / (160%)A = B / (8/5)A = 5B/8A = 0.625BA = (62.5%) B

Since A is 62.5% of B, it is 37.5% less than B.

Answer:

A. 37.5% less than B

Step-by-step explanation:

We can write an equation to model this:

B being 60% more than A means that:

B=0.6A+1A

B=1.6A

Let's isolate A.

A=B/1.6

Multiply the top and bottom by 10 to get whole numbers

A=10B/16

Simplify

A=5B/8

5/8 = 62.5%

A=0.625B

Therefore, A is 62.5% of B

This means that A is 37.5% less than B.

Write an equation in slope-intercept form for the relationship in the table.

Answers

The equation of the relationship in the table, in slope-intercept form, is: y = x + 5.

What is the Slope-intercept Form?

The slope-intercept form for a relationship between two variables x and y is represented as: y = mx + b, where:

m = slope = change in y / change in xb = y-intercept.

Slope (m) = change in y / change in x = 47 - 42 / 42 - 37 = 5/5

Slope (m) = 1

Substitute (37, 42) = (a, b) and m = 1 into y - b = m(x - a):

y - 42 = 1(x - 37)

y - 42 = x - 37

y = x - 37 + 42

y = x + 5

Equation for the relationship in the table is: y = x + 5
