Answer: The first day the author reaches 100 days is on day 16.
To solve this problem, you could use a graphing calculator to graph the given equation. Then, determine when this line crosses 100. It crosses when x = 15.539. Therefore, we would have to round up to 16 so it is at least 100.
You could use the quadratic equation to solve: 100 = x^2 -12x + 45
Either you will get 16. If you use the quadratic formula, make sure to only use the positive answer.
Answer:
slope = - 
Step-by-step explanation:
note that BC is perpendicular to AB, hence the slope of BC is the negative reciprocal of the slope of AB
= -
= -

Answer:
p(1/2) = 5
Step-by-step explanation:
Find the value of p(1/2) if p(x) = 2x^3 -x^2 + 10x
Set up synthetic div.:
1/2 ) 2 -1 10 0
1 0 5
------------------------
2 0 10 5
The remainder is 5, so we conclude that p(x) = 2x^3 -x^2 + 10x = 5 when x = 1/2.
