The question is on the image! one question, , i don't know how to do

1/4 b^-3/2  - 1/2 b^(-5)

Step-by-step explanation:

b^1/2 - 2 b^-3

4b^2

Separating into two fractions

b^1/2            2 b^-3

  --  

4b^2           4b^2

Remember when dividing exponents with the same base, we  subtract them

1/4 b^(1/2 -2)   - 2/4 b^(-3-2)

1/4 b^-3/2  - 1/2 b^(-5)

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints

no association

step-by-step explanation:

if you have eyes and you can use them efficiently you can see that it just looks like random dots like do a line of best fit and like they're so spread out it's such a weak association you might as well consider it nonexistent
