A doctor prescribes 150 milligrams of a therapeutic drug that decays by about 15% each hour. To the nearest hour, what is the ha

Nikolay [14]

Answer:

4 hours

Step-by-step explanation:

The amount remaining at the end of each hour is 0.85 of the amount at the start of the hour. You want to find the exponent such that ...

... 0.85^x = 0.5 . . . . . x = the number of hours until half is left

... x·log(0.85) = log(0.5) . . . . . take the log to turn it to a linear equation

... x = log(0.5)/log(0.85) ≈ 4.265024

Rounded to the nearest hour, x = 4.

List the domain of the following points from least to greatest: (-2, 4) (-6,8) (3,6) (5,15) (-1, 4)

nasty-shy [4]

Answer:

Domain = {-6, -2, -1, 3, 5}

Step-by-step explanation:

The domain represents the input or x values of a given relation.

In the given set of ordered pairs: (-2, 4) (-6,8) (3,6) (5,15) (-1, 4)

Domain (input/x values) = {-6, -2, -1, 3, 5}

Range (output/y values) = {4, 6, 8, 14}

A century year such as 1900, 2000, or 2100 is a leap year only if it is a multiple of 400

blondinia [14]

If this is a true or false question, then the answer is true. This is because we technically have 365.2425 days in a year and if you add an extra day every 4 years, you get an average of 365.25. It is A LOT of math, but even though there was an extra day in 1896 and 1904, there was no leap year in 1900 because of the 400 multiple rule.
