Emily is going to use a computer at an internet cafe. The cafe charges an initial fee to use the computer and then an additional price per minute of usage. A equation
representing the total cost of using a computer for t minutes at the internet cafe is
given by C = 9+0.50t. What is the slope of the equation and what is its
interpretation in the context of the problem?
The slope of the function is
which represents
the number of minutes the computer was used
the additional charge per minute
attempt 1 out of 2
the total charge of using a computer
the initial charge to use a computer

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.

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."

f(y)= y^2-10y+25
