How do i find the b value in a sine function when i know the period? the period is 15 and i need to find the b value.

b =

Step-by-step explanation:

The standard form of the sine is

y = asin(bx + c) + d

where | a | is the amplitude, period =

c is the phase shift and d the vertical shift

Here period = 15, thus

= 15 ( multiply both sides by b )

15b = 2π ( divide both sides by 15 )

b =

what is the question? i am guessing you are looking for the area.

to find an area, you have to do length x width.

in this case, it would be 12 ft x 4 ft = 48 sq. ft

choose (5, 1.5) and (-1.5,-3.5)

step-by-step explanation:

5 - 1.5 =3.5

-1.5 - (-3.5) = 2

3.5 + 2 =5.5

hope this !
