The position of a certain spring-mass system satisfies the initial value problem 3 2 u + ku = 0, u(0) = 2, u(0) = v. If the period and amplitude of the resulting motion are observed to be π and 3, respectively, determine the values of k and v.

Which expression is equivalent to sq-80

The solution set for 5v2 – 125 = 0 is

The weight of full–grown tomatoes at a farm is modeled by a normal distribution with a standard deviation of 18.4 grams. the 95 percent confidence interval for the mean weight of the tomatoes is calculated using a sample of 100 tomatoes. what is the margin of error (half the width of the confidence interval)?
