Recall newton’s law of cooling: the temperature of an object changes at a rate directly proportional to the difference between the ambient temperature and the object itself. use newton’s law of cooling to solve the following: an initial thermometer reading 75 f is taken outside where the temperature is 20 f . it is observed that 4 minutes later, the thermometer reads 30 f . find the thermometer reading 7 minutes after it was taken outside. (note: to receive full credit, you must write down the associated differential equation and solve it)

Me! #1 write an equation for the interior angles of this triangle that uses the triangle sum theorem. #2 what is the value of x? #3 what is the measure of #4 classify the triangle above as acute, obtuse, or right. state your reason in a complete sentence.

Astudent is determining the influence of different types of food on the growth rate of spiders. she feeds one group of spiders two caterpillars twice a week. the other group received similarly-sized beetles twice a week. she records the amount of time required for individuals to reach sexual maturity. her hypothesis is that the spiders feeding on caterpillars will have a faster growth rate because caterpillars have a higher protein content compared to beetles. in this experiment, what is the dependent variable? spiders assigned to different feeding groups. time required to reach sexual maturity number of prey items fed twice a week. growth rates of each group.
