State the domain and range for y=cos(-2x+180)+3

Mathematics
1 answer:
qwelly [4]3 years ago
4 0

Answer:

Domain: All real numbers

Range: 2\le x\le4

Step-by-step explanation:

The given function is

y=\cos(-2x+180\degree)+3

The cosine function is continuous everywhere so the domain is all real numbers.

The range of the parent function y=\cos(x)

is -1\le x\le 1.

The given function has been shifted up 3 units.

The range is

-1+3\le x\le 1+3.

2\le x\le 4.

Step-by-step explanation:

Storage Space of Shed = Volume of Shed.

Volume of Shed = Volume of Rectangular level

+ Volume of Triangular roof

Volume of Rectangular Level =

Length x Width x Height

=

12 \times 6 \times 8 \\  = 576 {ft}^{3}

Volume of Triangular Roof =

Area of Triangular side x Length

=

\frac{1}{2}  \times base \times height \times length \\  =  \frac{1}{2}  \times 6 \times 4 \times 12 \\  =  \frac{1}{2}  \times 288 \\  = 144 {ft}^{3}

Volume of Shed = 576 + 144

=

720 {ft}^{3}

Use a half-angle identity to find the exact value of sinPi/8
stellarik [79]

Answer:

  sin(π/8) = (1/2)√(2-√2)

Step-by-step explanation:

Using the half-angle formula ...

  \sin{\dfrac{\theta}{2}}=\sqrt{\dfrac{1-\cos{\theta}}{2}}

We can let θ = π/4 and simplify the result as follows:

  \sin{\dfrac{\pi}{8}}=\sqrt{\dfrac{1-\cos{(\pi/4)}}{2}}=\sqrt{\dfrac{1-\dfrac{\sqrt{2}}{2}}{2}}=\sqrt{\dfrac{2-\sqrt{2}}{4}}\\\\=\boxed{\dfrac{1}{2}\sqrt{2-\sqrt{2}}}}

Dave designed a circular pool with a diameter of 24 meters. What is the area of the bottom of the pool round the nearest tenth
kolezko [41]

Answer:

450 m²

Step-by-step explanation:

Area of a circle: \pi r^{2}

r is radius and we need to divide the diameter value by 2 to obtain the radius

= 24 / 2 = 12m

Area of a circle = \pi * 12^{2}

= 452.57

≈ 450 m²
