25 points! a hot bowl of soup cools according to newton's law of cooling. its temperature, t, (in degrees fahrenheit) at a time, t, is given by t(t)=66+131e^-0.05t, where t is given in minutes.

what should you plug in for time, t, to find the initial temperature, t, of the soup?

what's the initial temperature?

what was the temperature of the soup after 15 minutes?

how long after serving is the soup 120°f?

Which best explains why this triangle is or is not a right triangle?

1- is the product of two rational numbers irrational or rational? first, make a hypothesis by multiplying two rational numbers. then, use variables such as x=a/b and y=c/d and the closure property of integers to prove your hypothesis. 2- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis. 3- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in part b?

Erinn wrote the equation –5x + 4y = 32 to represent her hourly wage (y) and how this wage has changed during each year that she worked at a company (x). what is the rate of change in erinn's hourly wage per year?
