A fax machine is purchased for $5,800. Its value each year is about 80% of the value of the preceding year. So after t years the value, in dollars, of the fax machine, V(t), is given by the exponential function
V(t) = 5800 (0.8)t.
a. Give a sketch of the graph of the function V(t). Your READ MORE »
The population of honey bees in a region is infected by a parasite that kills off bees, so that the number of bees decreases with time. Numbers of bees are usually measured by the number of 'colonies' (groups of bees living
together) since it is very difficult to measure the e READ MORE »
I am in a fast-paced Calculus course where I must learn new concepts each week; I find it challenging to grasp the concepts while remaining on-pace and I am experiencing great difficulty. I am really finding it difficult to grasp the concept of Parametric & Rectangular Equations, Slope & Con READ MORE »
2π radians = 360 degrees = 1 cycle = 1 revolution
T (period in time/cycle) = 1/f (frequency in cycles/time), and ω = 2πf
For circular motion: s = rθ, where s = distance in units of length, r = radius, θ = angle in radians
ω = angular velocity (or angular frequency) in radians/time or revol READ MORE »
