Answer:
Step-by-step explanation:
hello :
f(x) = 10x²+20x-11 Completing The Square
f(x) = 10(x²+2x)-11 = 10((x²+2x+1)-1)-11
f(x) =10((x+1)²-1)-11
f(x)= 10(x+1)²-21...vertex form when the vertex is : (-1 ; -21)
The answer is $2,062.50
$1,100=1/3 + 1/5 of his money
therefore 1,100 = 5/15 + 3/15 = 8/15
I want to know what 15/15 is equal to
therefore I must first determine 1/15
1,100/8 = 137 1/2 = 1/15
The entire sum of money is 15/15 so it is 137 1/2 * 15 = $2,062.50
By the binomial theorem, the 
term in the expansion of 
is
which suggests that the contribution of the binomial coefficient should make up the remaining factor of 21. That is,
Answer:
The table at the very bottom.
