A) To the nearest inch, estimate the height of the maple tree
in 2011.
inches
B) Use the equation to find the year in which the tree will be
246 inches tall.
A newborn baby weighed 10 pounds at birth and was 15 inches tall. After 7 months the baby weighs 17 pounds and is 25 inches tall.
Part A: a) Write a linear function W(t) to represent the baby’s weight in pounds (W) at t months of age. Enter exact answers only, no approximations.
W(t)=
Part B: Write a linear function H(t) to represent the baby’s height in inches (H) at t months of age. Enter exact answers only, no approximations.
H(t)=
A collector of antique clocks sold at auction believes that the price received for the clocks may
be modeled as a linear function of the age of the clocks and the number of bidders at the auction.
After a preliminary study and collection of 32 observations, the collector came up with the
following second-order model:
y = BO+B₁x₁+B₂x₂ + ß3 x1x2 +B4x² +ɛ, where y: price of a clock; x₁: age of a clock; x2: the
number of bidders. Considering the output below and by setting a = 0.05, answer the following
questions.
The regression equation is
Price = 262 +2.26 Age + 14.2 Bidder + 1.13 AgeBid 4.20 Bid^2

Suppose the listener is free to move about the room to find those positions that receive equal amounts of sound from both speakers. Such a location satisfies two conditions: (1) the sound intensity at the listener’s position is directly proportional to the sound level of a source, and (2) the sound intensity is inversely proportional to the square of the distance from the source.
