6. What are the zeros for the function b(t) = (t -5) (t+3) (t-2)? A. {-5, -2,3}
B. {-3, 2,5)
C. {-5, -3,2}
D. {-2,3,5}

b(t) = (t -5) (t+3) (t-2)

zero of the function is given by

b(t) = (t -5) (t+3) (t-2)=0

such that

(t -5) (t+3) (t-2)=0

i.e.,  (t -5)=0 and   (t+3) =0  and   (t-2)=0

consider (t -5)=0

                t -5 =0

                t+5-5=0+5

                t=5

consider (t +3)=0

                t +3 =0

                t+3-3=0-3

                t= -3

consider (t -2)=0

                t -2 =0

                t+2-2=0+2

                t=2

answer is B

Step-by-step explanation:

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.
