Answer:

The absolute value of the product of the zeros of A(t) is 108

Step-by-step explanation:

We are given

[tex]A(t)=(t-k)(t-3)(t-6)(t+3)[/tex]

we have

A(2)=0

we can use it and find k

we can plug t=2 , A(t)=0

[tex]0=(2-k)(2-3)(2-6)(2+3)[/tex]

so, we get

[tex]0=(2-k)[/tex]

[tex]k=2[/tex]

now, we can plug it back

[tex]A(t)=(t-2)(t-3)(t-6)(t+3)[/tex]

now, we can find zeros

[tex]A(t)=(t-2)(t-3)(t-6)(t+3)=0[/tex]

[tex](t-2)=0[/tex]

[tex]t=2[/tex]

[tex](t-3)=0[/tex]

[tex]t=3[/tex]

[tex](t-6)=0[/tex]

[tex]t=6[/tex]

[tex](t+3)=0[/tex]

[tex]t=-3[/tex]

so, zeros are

[tex]t=-3,t=2,t=3,t=6[/tex]

now, we can find it's product

[tex]=-3\times 2\times 3\times 6[/tex]

[tex]=-108[/tex]

now, we can find it's absolute value

[tex]=|-108|[/tex]

[tex]=108[/tex]
