Prove that 1/sin^2A -1/tan^2A= 1
Vika [28.1K]

Answer:

Step-by-step explanation:

LHS =\dfrac{1}{Sin^{2} \ A }-\dfrac{1}{Tan^{2} \ A }\\\\\\ = \dfrac{1}{sin^{2} \ A}- \dfrac{1}{\dfrac{Sin^{2} \ A}{Cos^{2} \ A}}\\\\\\= \dfrac{1}{sin^{2} \ A } - \dfrac{Cos^{2} \ A}{Sin^{2} \ A}\\\\\\= \dfrac{1-Cos^{2} \ A}{Sin^{2} \ A}\\\\\\= \dfrac{Sin^{2} \ A}{Sin^{2} \ A}\\\\\\= 1 = \ RHS

Hint: 1 - Cos² A = Sin² A

Filomena applies the commutative property to the product. (7/15)⋅(−11)⋅(30) Which expression illustrates the commutative propert
dedylja [7]

  • The commutative property is a number property where the answer obtained is the same no matter the position of the numbers you are multiplying together.

  • Commutative property of multiplication is expressed as:

        a x b = b x a

        a x b x c = a x c x b = b x c x a

  • Note: " . " in the question also means "x" (multiplication)

  • Applying commutative property to the question:

(7/15)⋅(−11)⋅(30)

(7/15) ⋅ (−11) ⋅ (30) = (7/15) . (30) . (11)

The values interchanged are: 11 and 30. The result of the multiplication remains unchanged.

Option A  is the correct answer.

Lamar and Avalon are raking the leaves around a tree in their backyard. The has a diameter of 2 feet and is surrounded by a circ
DedPeter [7]
We have two cirlces:
big circle⇒ diameter=24 ft
small circle⇒diameter 2 ft

Area of the ground covered by leaves=area of the larger circle- area of the small circle.

1) we calculate the area of the larger circle
Data:
diameter=24 ft
radius=diameter / 2=24 ft /2=12 ft

Area of the larguer circle=πr²=π(12 ft)²=144π ft²

2)We calculate the area of the small circle
Data:
diameter=2 ft
radius=diameter/2=2 ft/2=1ft

Area of the small circle=πr²=π(1 ft)²=π ft²

3) we calculate the area of the ground covered by leaves.
area of the ground covered by leaves=144π ft²-π ft²=143π ft²≈143*(3.14) ft²=
=449.02 ft²

Answer: the area of the ground covered by leaves is 449.02 ft².
