The number of motorcycle helmets produced in a factory each day is a function of the number of hours (h) the assembly line is in operation that day and is given by n =
P(t) =
75t-2t^2. The cost C of producing the helmets is a function of C(n) = 7n + 1000

C(t)=525t-14t²+1000

Step-by-step explanation:

n =P(t) =75t-2t²

C(n) = 7n + 1000

(sub in 75t-2t² for n)

C(t)=7(75t-2t²)+1000

C(t)=525t-14t²+1000

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
