The function f(t) represents water going into a swimming pool with respect to the number of hours(t) water is flowing in where(t) represents time. f(t)=t squared +8t+9

There is a leak in the pool and it’s losing water at a rate represented by d(t)
d(t)=t squared +11t+4

a. Write a function to represent the amount of water in the pool using the two functions.
b. Use the new function w(t) to determine if the pool will leak all of the water.
c. If the pool will drain of all water, how much time will it take?
d. Will f(t) and d(t) intersect on a graph? Explain what it means if they do.
e. What is the domain of f(t),d(t) , and w(t). Explain your answer.

i recommend you do what your heart desires. if you're attracted to the same gender, then you're attracted to the same gender. you can't determine what your heart wants.

step-by-step explanation:

there is only one way to arrange all the eight relative to each other because they are not distinct. we have

now there are nine places to place an (and not more than one in one place).   because we have four symbols, we need to choose four of these nine places to insert an . order does not matter because the are not distinct.

thus there are 1 · c(9,4) ways, or, if we calculate it,

thus there are 126 ways to form such "words."
