Processor Speeds The processor speed, in megahertz (MHz), of Intel processors during the period 1970-2000 could be approximated by the following function of time t in years since the start of 1970: 54 v ( t ) = { 3 t if 0 ≤ t < 20 174 t − 3 , 420 i f 20 ≤ t ≤ 30 How fast and in what direction was processor speed changing in 1995?

The number of vocabulary is a function of the child's age. The formula for the size of vocabularies for typical children between the ages 20 months and 50 months is given by n= 60a - 900 , where a represents the child's age in months and n represents the number of words that the child uses correctly. How many words does a typical child learn each month from age 20 months to age 50 months?
Select one:
a. 50 words/month
b. 60 words/month
c. 70 words/month
d. 80 words/month
A certain ferris wheel has a radius of 140
feet, and the center of the ferris wheel is
160 feet from the ground. It makes one
complete revolution every minute. Write a
function for the height of a seat (in feet) from
the ground after t minutes.
