Answer:
To calculate permutations, we use the equation nPr, where n is the total number of choices and r is the amount of items being selected. To solve this equation, use the equation nPr = n! / (n - r)!.
1) In a proportion: y/x=k
k is your constant of proportionality.
x is your independent variable and y is your dependent variable.
Since you need 3 oz of flour for each 2 oz of sugar, y=3 and x=2.
So k=1.5 (3/2)
3)
a) y/x as a showed above. This question is very similar to #1.
b) y/x=k
The equation that is equivalent is -2+(-7).
SinA=cos(90-A)
Notice here 52=90-38
so the answer is 0
The number that u could use for Descartes rule and the fundamental theorem of algebra to predict is 200,000 and 900
