Colleen recently purchased a farm that raises chickens. since she has never raised
chickens before, colleen wants to learn as much about her baby chicks as possible.
in particular, she wants to know how much a baby chick weighs when it is hatched.
to find out, colleen decided to track the weight of one of the chicks that was born
just before she purchased the farm. she found that her chick grew steadily by about
5 grams each day, and she assumes that it has been doing so since it hatched. nine
days after it hatched, the chick weighed 98 grams.

yx = 36

step-by-step explanation:

cos f = opposite side/ hypotenuse

cos f = yw / yx

we know cos f = 4/9 and yw =16

4/9 = 16/yx

multiply each side by yx

4/9 yx = 16/ yx * yx

4/9 yx = 16

multiply each side by 9/4

9/4 * 4/9 yx = 16 *9/4

yx = 36

\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?
