What are the amplitude, period, and phase shift of the given function? f(t)=-1/2sin(3t-2pi)

amplitude = 1/2

phase shift = 2/3 pi

period = 2/3 pi

Step-by-step explanation:

the amplitude is what comes before the sine (but without the negative)

the period is 2pi/B, B here is 3

and the phase shift is -C/B or -(-2)/3 = 2/3 pi

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
