Under normal conditions, the atmospheric temperature drops 3.5°f per 1000 feet of altitude up to 40,000 feet. when the outside temperature is 80°f, the atmospheric temperature can be modeled by t(x) = − 3.5x + 80, where x is the altitude in thousands of feet.
a. graph the function and identify its domain and range.
b. find and interpret the value of x so that t(x) = − 25

There is a theory that indicates that dinosaurs became extinct when about 65 million years ago, a large asteroid hit the earth surface. dust caused by this collision blocked the sunlight reaching the earth's surface and many forms of life became extinct due to the cold. fearing this threat, how large the radius of an asteroid should you be looking for if the dangerous asteroid size is approximately the same as the one that killed the dinosaurs? available data suggests that about 18% of that asteroid's mass ended up as a dust spread evenly over earth after eventually settling out of the upper atmosphere. about 0.0180 g/cm^2 of dust, which is chemically different than the earth's rock, covered the earth's surface. typical asteroids have a density of about 1.9 g/cm^3. now that we know the size of the asteroid, how much energy was released during impact, assuming all of it was just the kinetic energy of the asteroid right before the impact?

A0.580-kg rock is tied to the end of a string and is swung in a circle with a radius of 0.500 meters. the velocity of the rock is 4.50 m/s. what is the centripetal force acting on the rock? 15.5 n 5.22 n 69.8 n 23.5 n

If two parallel light rays hit a mirror, they will not be parallel to each other after they reflect.
