Two scuba divers, Jim and Tara, are 20m apart below the surface of the water. They both spot a shark that is below them. The ang

Answer:

Jim is 12.87 meters away from the shark.

Step-by-step explanation:

We are given that,

Distance between Jim and Tara = 20 meters.

The angle of depression of the shark from Jim and Tara is 47° and 40° respectively as shown in the figure below.

So, the third angle of the triangle formed is given by,

47° + 40° + ∠S = 180°

i.e. ∠S = 180° - 87°

i.e. ∠S =93°

So, now using the sine ratio formula, we have,

\frac{20}{\sin 93}=\frac{x}{\sin 40}

i.e. x=\frac{20\times 0.6428}{0.9986}

i.e. x=\frac{12.856}{0.9986}

i.e. x = 12.87 meters

Thus, Jim is 12.87 meters away from the shark.

Crank

Answer:

There is a horizontal translation 4 units left, and and vertical translation 1 unit down.

Step-by-step explanation:

To find the transformation, compare the function to the parent function and check to see if there is a horizontal or vertical shift, reflection about the x-axis or y-axis, and if there is a vertical stretch.

Parent function: f(x) = (5)^x

Horizontal translation: 4 units left

Vertical translation: 1 unit down

Reflection about the x-axis: none

Vertical stretch: stretched

Step-by-step explanation:

<u>Use the Pythagorean theorem:</u>

  • a² + b² = c²

<u>Verify this for each line:</u>

1.

  • 28² + 45² = 53²
  • 2809 = 2809
  • Yes

2.

  • 33² + 56² = 64²
  • 4225 ≠ 4096
  • No

3.

  • 36² + 77² = 85²
  • 7225 = 7225
  • Yes
