N=-3/20
In decimal form it would be n=-0.15
Answer:
Brook is faster.
Step-by-step explanation:
1 hour=60 minutes
2 hours=2*60=120 minutes
-------------
7 miles in 30 minutes vs 25 miles in 120 minutes
7/30=0.233...mile per minute
25/120=0.20833...mile per minute
(2x-3)(x+5)
Use foil to simplify, First multiply together the first terms of the pairs, then the outer terms, the middle terms, and finally the last terms. Then combine like terms.
2x^2+10x-3x-15 equals 2x^2+7x-15
Step-by-step explanation:
Since f(0) = f(5) = f(8) = 0, we have f(x) = Ax(x - 5)(x - 8), where A is a real constant.
We know that f(10) = 17.
=> A(10)(10 - 5)(10 - 8) = 17
=> A(10)(5)(2) = 17
=> 100A = 17, A = 0.17.
Hence the answer is f(x) = 0.17x(x - 5)(x - 8).
