The time it takes for a TV repair master to finish his job (in hours) has a density function of the form
f(x)={c(x-1)(x-2)0 if 1 a) Determine the constant c.
b) What is the probability that a TV repair master will finish the job
in less than 75 minutes? Between 3/2 and 2 hours?

true

step-by-step explanation:

m∠5 + m∠3 = m∠1   is true.

m∠5 + m∠6 = 180 is true

m∠2 +m∠3 = m∠6   is true

m∠2 +m∠3 +m∠5 = 180   is true

step-by-step explanation:

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b
