(05.03 HC)

There are 15 people in the chorus. Each year, the number of people in the chorus increases by 12%. There are 30 people in the band. Each year, 2 new people join the band.

Part A: Write functions to represent the number of people in the chorus and the number of people in the band throughout the years. (4 points)

Part B: How many people are in the chorus after 9 years? How many people are in the band after the same number of years? (2 points)

Part C: After approximately how many years is the number of people in the chorus and number of people in the band the same? Justify your answer mathematically. (4 points)

(10 points)

570, the answer is 570, hope it

\3. yes the presentation (i.e. odd numbers being written as differences of two squares) is possible for all odd natural number however the presentation may not be unique. for example,  57=112−82=292−28257=112−82=292−282.

\4. 2 can't be written as a difference of two squares because 4-1=3 and 1-1=0 and the difference of squares grows to integers larger that 3.

can i get some in proving questions 1 and 2?

this equation is in point-slope form.

where,

using this equation you can gather a point and the slope, which gives you enough information to draw a line. transform the equation to standard form to start.

the equation is now in standard form, we have a point, as well as the slope:

point: (0, -6)

slope: -2

plot (0,-6), then simply rise/run with the provided slope of -2, once you feel you have a comfortable amount of points - draw a line.

turn 2 ft into 24 inches. then divide both numbers by 6 getting you 4 and 9. now make the fraction have a numerator of 4 and a denominator of 9, the answer is 4/9.
