whats the surface area? sorry if im annoying

The machine has a mass m and is uniformly supported by four springs, each having a stiffness k.Determine the natural period of vertical vibration(Figure 1)Express your answer in terms of some or all of the variables m, k, and constant pi. What is the probability of selecting two cards from different suits with replacement? use a 2-year weighted moving average to calculate forecasts for the years 1992-2002, with the weight of 0.7 to be assigned to the most recent year data. ("sumproduct" function must be used.) an object is executing simple harmonic motion. what is true about the acceleration of this object? (there may be more than one correct choice.) If Head Start is effective enough to receive continued funding, why wouldnt we choose to fund it at levels that would guarantee a space to every eligible child? using the volume you just calculated, determine the moles of edta that reacted with the calcium ions. 2012 Virginia Lyme Disease Cases per 100,000 Population D.RU 0.01 - 5.00 5.01. 10.00 10.01 - 25.00 25.01 - 50.00 5001 - 10000 100.01 - 215.00 Duben MA CH Alter Situs Gustige 07 Den Lubus Fune Des SERE Teild MON About11.

(a) If the jury must consist of 6 men and 6 women, how many different juries are possible? (b) Again suppose that the jury must consist of 6 men and 6 women. Suppose too that the jurors must be seated so that no two people of the same sex are seated next to each other. How many different seating arrangements are possible? (Note that Im not saying that we know which men and women are on the jury at first. You need to count the number for each possible jury seating for each possible jury.)
