Apharmacist whishes to mix a solution that is 6% minoxidil. she has on hand 100 ml of 4% solution and wishes to add some 8% solution to obtain the desired 6% solution. how much 8% solution should she add?

100

Step-by-step explanation:

Let x be the amount to be added of the second solution. For every 100ml of it 8 units of minoxidil are added. The total amount of solution will be (100 + x), so the final concentration is given by:

 [Multiplying by (100 + x)]

                           [Transposing terms]

                             [ operating]

                                                [Dividing by 0.02]

answer: $1794

step-by-step explanation:

hello,

as we don't know if g(x) is continue,

answer b

f(x)=2x²-8x+1=2(x²-4x+4)+1-8=2(x-2)²-7

vertex is (2,-7) ( a minimum since coefficient of x² is > 0)
