Solve the following equation for 0° ≤ θ &lt; 360°. Use the "^" key on the keyboard to indicate an exponent. For example, sin2x w
never [62]

<u>Answer-</u>

\boxed{\boxed{x=90^{\circ},270^{\circ}}}

<u>Solution-</u>

The given equation-

\Rightarrow 2\sin^2 x-\cos^2 x-2=0

As

\sin^2 x+\cos^2 x=1\ \ \Rightarrow \cos^2 x=1-\sin^2 x

Putting this,

\Rightarrow 2\sin^2 x-(1-\sin^2 x)-2=0

\Rightarrow 2\sin^2 x-1+\sin^2 x-2=0

\Rightarrow 3\sin^2 x-3=0

\Rightarrow 3\sin^2 x=3

\Rightarrow \sin^2 x=1

\Rightarrow \sin x=\sqrt1

\Rightarrow \sin x=\pm 1

\Rightarrow \sin x=1,\ \sin x=-1

\Rightarrow x=\sin^{-1}(1),\ x=\sin^{-1}(-1)

\Rightarrow x=90^{\circ}+n360^{\circ},\ x=270^{\circ}+n360^{\circ}

Where n=0, 1, 2, ......

As given 0° ≤ x < 360°, so putting n = 0

\Rightarrow x=90^{\circ},\ x=270^{\circ}

a recipe for one batch of cookies calls 1 1/2 cups of flour how many cups of flour are needed for 3 batches
iris [78.8K]
Since 1 batch needs 1 1/2 cups. You simply have to multiply 1 1/2 x 3.

4 1/2 cups are needed to bake 3 batches.

Three squares. The first square is labeled with side length 1 inch on the vertical side and 1 inch on the horizontal side. The s
dlinn [17]

Answer:

The area is the side lengths squared or multiplied by themselves. The three squares have very different areas based on their side lengths. I disagree that a square with 13 inch side length will have area 13. It will have area 13*13=169 square inches.

Step-by-step explanation:

The area of a square is A=s*s.

1st: A = 1*1 = 1 square inches.

2nd: A=1/2*1/2 = 1/4 square inches

3rd: A =2*2 = 4 square inches.

The area of a square with 1 unit side length is still 1. But a square whose side is less than 1 has a very small area and the square whose side length is greater than 1 has a much larger area. The area of a square is the square of its side length or its side length times itself.

Knowing this, a square with side length 13 will not have area 13 but area 169.
