What is the amplitude, period, and phase shift of y= 5cos( x/2 + 2pi/3)

nordsb [41]

Y = A cos(Bx + C)
A - amplitude
$\frac{2\pi}{B}$ - period
$- \frac{C}{B}$ - phase shift

$y=5\cos{( \frac{x}{2} + \frac{2\pi}{3} )}
\\
\\y=5\cos{( \frac{1}{2}x + \frac{2\pi}{3})}
\\
\\A=5,B= \frac{1}{2},C= \frac{2\pi}{3}$

Amplitude: 5
Period: $\frac{2\pi}{B}=\frac{2\pi}{\frac{1}{2}}=4\pi$
Phase shift: $- \frac{C}{B} =- \frac{\frac{2\pi}{3}}{\frac{1}{2}}= -\frac{4\pi}{3}$

The length.of a hypotenuse of a right triangle is 32feet and the length of one of the lrgs is 18 feet. what is the length, to th

gayaneshka [121]

Use Pythagorean's Theorem to solve for the missing leg length.

$32^2-18^2=a^2$

with a being the length of the missing leg. Simplifying we have

$1024-324=a^2$

and

$a^2=700$ . If we are told to express our answer to the nearest tenth of an inch, then we are simply plugging that into our calculator to get 26.45 or, rounded correctly, 26.5

F(x)=x3 −4x even odd or neither

Dennis_Churaev [7]

The answer is neither.

Let's take an odd number and substitute.

f(3) = 3³ - 4(3)
f(3) = 27 - 12
f(3) = 15 (odd)

Now, let's take an even number.

f(4) = 4³ - 4(4)
f(4) = 64 - 16
f(4) = 48 (even)

Since both even and odd numbers are possible, it is neither.
