A galaxy G is moving away radially with speed with respect to an observer O. The relation between X, the wavelength of light emitted at G, and λo, the wavelength observed at O, is 入。 λ = λe λε 1+B 1- B' = where ẞ v/c (c is the speed of light). For ẞ < 1 find a power series expansion of the above formula up to and including terms of order ẞ³.

The arc length formula says the length sof arc subtended by angle in a circle of radius r is given by the equation s=r . What are the dimensions of (a) s, (b) r , and (c) ?

A 11-inch candle is lit and burns at a constant rate of 1.3 inches per hour. Let t represent the number of hours since the candle was lit, and suppose R is a function such that R(t) represents the remaining length of the candle (in inches) t hours after it was lit. a. Write a function formula for R in terms of t. R(t)=11-1.3t Preview b. What is the domain of R relative to this context? Enter your answer as an interval. [0,8.46] Preview c.
