Determine the amplitude or period as requested. Period of a y = - 1/3 * sin x - 1/3 pi/3 1/3 d 2pi

zysi [14]

Answer:

$Period = 2\pi$

Step-by-step explanation:

Given

$y = -\frac{1}{3} * \sin(x - \frac{1}{3})$

Required

Determine the period

A sine function is represented as:

$y =A \sin(Bx + C) + D$

Where

$Period = \frac{2\pi}{B}$

By comparing:

$y =A \sin(Bx + C) + D$ and $y = -\frac{1}{3} * \sin(x - \frac{1}{3})$

$Bx = x$

So:

$B = 1$

So, we have:

$Period = \frac{2\pi}{B}$

$Period = \frac{2\pi}{1}$

$Period = 2\pi$

Hence, the period of the function is $2\pi$

2. Triangle ABC is equilateral and AB = 6x + 3, BC = 8x - 1,2. AB =

kherson [118]

Answer:

AB = BC = AC = 15

Step-by-step explanation:

Since the triangle is equilateral then the 3 sides are congruent.

Equate any 2 sides and solve for x , that is

AC = AB , so

11x - 7 = 6x + 3 ( subtract 6x from both sides )

5x - 7 = 3 ( add 7 to both sides )

5x = 10 ( divide both sides by 5 )

x = 2

Then

AC = 11x - 7 = 11(2) - 7 = 22 - 7 = 15 , thus

AB = BC = AC = 15

ANEK [815]

Answer:

mean =median, so the data is symmetrical

Step-by-step explanation:

Given

Data set= {10,5,8,10,12,6,8,10,15,6,12,18}

Mean= Sum of data points/number of data points

= (10+5+8+10+12+6+8+10+15+6+12+18)/12

=10

Median= mid value

={5,6,6,8,8,10,10,10,12,12,15,18}

Middle values are 10 and 10

Median = 10+10/2

= 20/2

= 10

Mean= median so there will be no skewness and the distribution is equal !
