132. a patient in a hospital needs to maintain a certain amount of a medication in her bloodstream to fight an infection. suppose the initial dosage is 10 mg, and the patient is given an additional maintenance dose of 4 mg every hour. assume that the amount of medication in the bloodstream is reduced by 25% every hour.
b. write a function that models the total amount of medication in the bloodstream after n hours.

step-by-step explanation:

∆abc has the points a(1, 7), b(-2, 2), and c(4, 2) as its vertices. formed with the point d(1, 2) as its third vertex, then ∆abd is triangle.

1. d.90

2. e. none of these (80)

3. a. 0

4. b. 6

5. e. none of these (10)

6. a. 5

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
