Solution Summary: The author explains how to calculate the frequency for C two octaves above the middle on a piano.
The vibration of sound is measured in cycles per second, also called hertz (Hz). The frequency for middle
C
on a piano is
256
Hz
. The
C
above middle
C
(one octave above) is
512
Hz
. The frequencies of musical notes follow a geometric progression.
a. Find the frequency for
C
two octaves above middle
C
.
b. Find the frequency for
C
one octave below middle
C
.
Convert the given Fahrenheit temperature to its equivalent temperature on the Celsius scale. Use C = (F-32) or
F=C+32, where F is the degrees in Fahrenheit and C is the degrees in Celsius.
73°F
73°F=°C

a. Clara cycles at a constant speed of 5 meters per second from west to east along a path. She passes a road sign
during her ride. If t represents the mumber of seconds since Clara was 17 meters east of the road sign, write an
expression to represent Clara's distance east of the road sign.
Distance Clara is East of the road sign
meters.

c. The applet below shows two line segments whose lengths represent the values of A and B. In the applet, you
can vary both A and B by dragging the purple X's at the ends of the line segments.
Set the applet so that A is 22.5 units long and Bis 4.5 units long.
