A detective is called to the scene of a crime where a dead body has just been found. She arrives on the scene at 5:00pm and begins her investigation. Immediately, the temperature of the body is taken and is found to be 26.5 C. The detective checks the programmable thermostat and finds that the room has been kept at a constant 18C for the past 3 days.
After evidence from the crime scene is collected, the temperature of the body is taken once more and found to be 24 C. This last temperature reading was taken exactly ONE hour after the first one. The next day the detective is asked by another investigator, “What time did our victim die?” Assuming that the victim’s body temperature was normal (37 C) prior to death, what is her answer to this question? Newton's Law of Cooling can be used to determine a victim's time of death.

How would I solve for the variables to the equation f(x)=ab^x+c using the above information??

how many seconds will a ball take to reach a height of 200 ft?

h = -16x^2 + 28 x +144

h = height and x = time ( second )

I know that I have to plug in 200 into h and solve for x
but I just can't get an answer... can anyone help me with this?

I don't remember A LOT about limits with trig. functions. We're reviewing and I'm having so much trouble.

We haven't done L'Hopital's rule, so please don't suggest it. People have tried to help me solve it this way but I just cannot understand it. There needs to be another way to solve these limits.

Please, please help me out?

There are questions like:

Lim x-->0 (tan πx/ x)
Lim x---> infinity (x^2 sin(1/x)
lim x--> 0 (x csc x)

Do I use the quotient rule? Or...? I'm so confused!

Please help me. My HW is due tomorrow and I'm desperate for help!

Thank you SO much!
