5.4.8* In Problem 5.22, we solved this problem:
I bought a new comic book at the Comic Book Shoppe and paid entirely using
quarters. If I had instead paid using only dimes, I would have needed 9 more coins.
How much did the comic book cost?
A solution by assigning a variable to the number of quarters I used to buy the comic book
However, it is possible to find the solution by assigning a variable to the cost of the comic book

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²

he kicked it up? is this the answer ?

step-by-step explanation:

tip $2.90

total $17.40

1. when "a" is a root of a polynomial, (x -a) is a factor of it. for the three roots given, the factors of the desired polynomial are (x +2)(x -1/2)(x -3).

in order to make the leading coefficient be negative, we need to multiply this product by a negative number. any negative number will do, but we choose a small (magnitude) value that will eliminate the fraction: -2.

then

f(x) = -2(x +2)(x -1/2)(x -3) = -(x +2)(2x -1)(x -3)

= -(2x² +3x -2)(x -3)

= -(2x³ -3x² -11x +6)

f(x) = -2x³ +3x² +11x -6

2. a graph created by the desmos on-line graphing calculator is shown, and the zeros are highlighted.

3. as indicated in part 1, the multiplier of this equation can be anything and the zeros will remain the same. you want a negative leading coefficient, so the "anything" is restricted to any of the infinite number of numbers that will make that be the case.
