When a liquid is placed into a refrigerator, its temperature T°C at a time t minutes is given by the formula T=T*10^-kt The temperature is initially 100°C and drops to 40°C in 5 minutes. Find...

having trouble solving for x can you help me out step by step to solving x

So, in all, I'm really just asking how I would use log in general. (Please answer in a 'for dummies' format please! :) Not exactly the best with the vocabulary!) Due to some research, I've learned...

On a graph, graph the function f(x)=a^x and g(x)=log sub a x when a=2, a=.5 and a=1. how many points of intersection does each value of a produce ?

The logistical growth function f(t) = 77,000/1 + 1539.0e^-1.3t models the number of people who have become ill with a particular infection t weeks after its initial outbreak in a paticular community...

what would the exponential regression question be that models the number of grams remaining? y, after x number of days

Create a formula then find the temp of the pie after 120 minuites

For every half life how many # of days and grams remaining?

I don't know the transformations neither do I know which one will give me a y-intercept
