Determine the amplitude or Period as requested. Period of y= -2 sin x

Alex Ar [27]

amplitude: 2

period: 2pi

The equation for a sin function is:

$y = a \sin(b(x - c) ) + d$

a = the amplitude

b = the period

c = the horizontal shift

d = the vertical shift

the equation to find the period of a sin function is:

$period = \frac{2\pi}{b}$

note: the amplitude is always a positive number, if there is a negative sign in front of it then that means it reflects over the x-axis.

Answer:

y = 1/5x - 6/5

Step-by-step explanation:

Step 1: Write out known variables

m = 1/5

y = 1/5x + b

Step 2: Find b

-1 = 1/5(1) + b

-1 = 1/5 + b

b = -6/5

Step 3: Write linear equation

y = 1/5x - 6/5

Answer:

Relative frequencies

First row

0.8125 ,0.1875 ,16

Second row

0.555 ,0.444 ,9

third row

18 , 7 , 25

Step-by-step explanation:

Given data

allowance No allowance total

Chores 13 3 16

No chores 5 4 9

Total 18 7 25

Relative frequencies

allowance No allowance total

Chores $\frac{13}{16} = 0.8125$ $\frac{3}{16} = 0.1875$ 16

No chores $\frac{5}{9} = 0.555$ $\frac{4}{9} = 0.444$ 9

Total 18 7 25
