1) State the amplitude, period, phase shift, vertical shift and graph

bogdanovich [222]

Answer:

See answers and explanations below (along with a visual graph)

Step-by-step explanation:

For the function $y=acos(b(x+c))+d$ :

Amplitude: $|a|$

Period: $\frac{2\pi}{|b|}$

Phase shift: $\frac{-c}{b}$

Vertical shift: $d$

Therefore, for $y=2cos(\frac{2}{3}(\theta+\pi))-1$ :

Amplitude: $|a|=|2|=2$ , which is 2 units above and below the midline (see d)

Period: $\frac{2\pi}{|b|}=\frac{2\pi}{|\frac{2}{3}|}=\frac{2\pi}{\frac{2}{3}}=3\pi$ , so the cycle will repeat every 3π units

Phase shift: $\frac{-c}{b}=\frac{-\frac{2\pi}{3} }{\frac{2}{3} }=-\pi$ , or π units to the left

Vertical shift: $d=-1$ , or 1 unit down

Answer:

$\sqrt32$

Step-by-step explanation:

You use the Pythagorean theorem since a triangle is formed.

$a^{2} +b^{2} =c^{2}$

$6^{2} = 2^{2} +x^{2}$

36-4 = $x^{2}$

x= $\sqrt{32}$

Maria is putting up a shelf on a wall in her closet. The figure below shows triangle ABC, which

Degger [83]

To solve this you will need to know the Pythagorean therum A^2+B^2=C^2

24^+B^2=28^2
576+B^2=784
-576. -576
B^2=208
Square root of 208 is about 14.42 and that is the length of the wall
