A cardiac monitor is used to measure the heart rate of a patient after surgery. It compiles the number of heartbeats after t minutes. When the data table is graphed, the slope of the tangent line represents the heart rate in beats/min. The monitor estimates this value by calculating the slope of the secant line. Use the data (points provided) to estimate the patient's heart rate after 42 minutes using the secant line between the points with t=38 and t=42.

Points provided: (36,2540), (38,2650), (40,2880), (42,2990), (44, 3040)

They say that god is supernatural and can do absolutely anything. Without magic or illusion, could he make a square into a circle and a triangle into a square? How come he has no control over mankind and the scientific universe?

Like in the movie gattaca. They look at your intelligence and any defects like a bad heart. Employers currently use: psychological tests, drug tests, credit check, background check. (this is for example used by PRiVATE banks)

They could also use the drug test without letting you know they did it.

Ideal gas law: PV=nRT
(*=degrees)
A mass of 5g of solid(specific heat 2.08 J/g.K) initially at 100*C is droppe into a beaker containing 100g of water (specific heat 4.18 J/g.k) initially at 25*C. Assuming that the heat lost by the solid is gained by the water body, find the final temperature of the system (water + solid).

a)26.8*C
b)30.2*C
c)36.8*C
d)50.0*C

a typical car gets 30 mpg of gas & drives 12000 mi per yr. assuming that octane (C8H18 density 0.07025) is a principal component of gasoline;
a. how much oxygen is required for a car to run for 1 yr?
b. how many grams of CO2 is produced by a car in 1yr?

the chemical formula for gasoline is :
2 C8H18 + 25 O2 -> 18 H2O + 16 CO2

I have a friend who has a BROTHER that is a meteorologist, so he thinks he's a meteorologist, too. Last weekend, I left his Super Bowl party and it was COLD. My truck has an outside thermometer built in and it showed a temp of 6°F. I got home and called him to let him know we got home ok & he told me the temp was 11°. I told him our truck showed 6. He says that's because the WIND VELOCITY made it colder. Now....I know about wind chill, and it shouldn't affect my truck's thermometer. At least, that's what I think. Anyone know for sure? Can you point me to a website that I can reference? I've looked, but can't seem to find anything.
