A bird (B) is spotted flying 6,000 feet from a tower (T)). An observer (O) spots the top of the tower (T) at a distance of 9,000
Flura [38]

Answer:

∅ ≈ 56.31°

Step-by-step explanation:

The bird is spotted flying 6000 ft from a tower . The distance of the tower from the bird is 6000 ft. The height of the tower is 9000 ft because the observer spot the distance from the top of the tower at a distance of 9000 ft.

The illustration forms a right angle triangle. The adjacent side of the triangle is  6000 ft and the height or opposite side of the triangle is 9000 ft. Using tangential ratio the angle of depression from the bird to the observer can be found as follows.

Let

∅ = angle of depression

tan ∅ = opposite/adjacent

tan ∅ = 9000/6000

tan ∅ = 1.5

∅ = tan⁻¹ 1.5

∅ = 56.309932474

∅ ≈ 56.31°

Find all roots.<br> 11) x^3 + 6x² + 5x = 0
Dmitrij [34]

Answer:

x=0

x=-1

x=-5

Step-by-step explanation:

To find the roots, we set the equation equal to zero and factor.

x(x²+6x+5)=0           [factor]

x(x+1)(x+5)=0            [set each factor equal to 0]

x=0

x+1=0                       [subtract both sides by 1]

x=-1

x+5=0                      [subtract both sides by 5]

x=-5

Now, we have found three roots, x=0, x=-1, x=-5.

The length is 12 cm more than its width . Find the area of the rectangle if it's perimeter is 100 cm
DaniilM [7]
Let's say the width is (x) and the width is (x+12). The formula for a perimeter of a rectangle equals 2w + 2l, which would then for this problem be 100=2(x) + 2(x+12) which would distribute as 2x + 2x + 12 which equals 4x+12. When you subtract twelve from 100 you get 88=4x. Divide 88 by 4 and you get x=22. This then would mean the width is 22 and the length is 34. The formula for an area of a rectangle is w*l. Plug in the numbers that you figure out from the area formula and you get 22x34=748
