A student uses the equation tangent theta = StartFraction s squared Over 49 EndFraction to represent the speed, s, in feet per second, of a toy car driving around a circular track having an angle of incline Theta, where sine theta = one-half. To solve the problem, the student used the given value of sine theta to find the value of tangent theta and then substituted the value of tangent theta in the equation above to solve for s. What is the approximate value of s, the speed of the car in feet per second?

Global warming will produce rising sea levels partly due to melting ice caps but also due to the expansion of water as average ocean temperatures rise. to get some idea of the size of this effect, calculate the change in length of a column of water 1.00 km high for a temperature increase of 1.00ºc. note that this calculation is only approximate because ocean warming is not uniform with depth. (answer in ×10^{-3} −3 m)
