By the binomial theorem,

I assume you meant to say "independent", not "indecent", meaning we're looking for the constant term in the expansion. This happens for k such that
12 - 3k = 0 ===> 3k = 12 ===> k = 4
which corresponds to the constant coefficient

Answer:
Step-by-step explanation:
Let h bet the # of hours worked
If Cynthia earns $13 per hour then her equation would be:
C = $13h
If Amy makes $1.5 more per hour then her equation would be:
A = $14.5x
Now lets plug in some numbers:)
A = $14.5(43.5)
A = $630.75
Answer: answer is A. 80 degrees and 100 degree

Answer:
0.79 sec
Step-by-step explanation:
Given there is a tool at the top of the building which is dropped by a worker and it follows the following equation at every instant of time .

where 
We know that this height is measured from the base of the building which means that when the tool reaches the bottom of the building it has h = 0 feet.
Let this be done at time t
h(t) = 0



t = 0.79 sec
Therefore the total time taken by the tool to reach the bottom of the building is 0.79 sec.
