A protected coastal wildfire area is surveyed and sampled for various forms of wildlife. the protected area is essentially recta

ngular in shape,92 miles long and 3.5 miles wide. several 50 foot square sections were sampled throughout the area. the average population of a certain insect species in each section was 17.
a. determine the area of the protected area and convert it to square feet. (express your answer in a scientific notation.)

b. compute the area of each section that was sampled, and determine the average population of this insect per square foot. ( express your answer in scientific notation.)

c. what is the estimated population of this insect within the boundaries of the protected wildlife area? (express your answer in a scientific notation.)

Help on precal, what are the answers?

1) cscΘ = - 2

=>

        1
      ------ = - 2
      sinΘ

=> sinΘ = - 0.5 => Θ is in the third and fourth quadrant

=> Θ = 180° + 30° = 210°

and Θ = 360° + 30° = 330°

2) tan Θ = √3

=> Θ = 60° and Θ = 180° + 60° = 240°

2. Use the following picture for this question:
Art [367]

Answer:

a.  24\sqrt{3}  and 41.6

b.  52.1

Step-by-step explanation:

a.

Considering the left side triangle the blue dotted side is the side "opposite" to the angle given and the side 24 is the side that is "adjacent" to the angle given. The trigonometric ratio tan relates opposite to adjacent. Also, let the blue dotted side be y.

<u>Note:</u> the exact value of tan 60 is \sqrt{3}

Thus, we can write Tan(60)=\frac{y}{24}\\y=24*Tan(60)\\y=24*\sqrt{3} \\y=24\sqrt{3}

Approximate value (rounded to nearest tenth):  24\sqrt{3} =41.6

b.

Considering the triangle to the right, the side "opposite" to the angle given (53 degrees) is 41.6 (just found in part (a)) and the side "hypotenuse" (side opposite to 90 degree angle) is x. The trigonometric ratio sine relates opposite and hypotenuse.

Thus we can write and solve:

Sin(53)=\frac{41.6}{x}\\x=\frac{41.6}{Sin(53)}=52.1
