A glass factory makes a continuous ribbon of glass by pouring a continuous stream of hot liquid silicon on a lake of molten tin. The liquid silicon spreads out evenly on the tin and then cools into glass. It is a process that must continue uninterrupted hours a day, so adjustments to equipment and materials are ongoing. Assume that inspectors work eight-hour shifts, watching the glass ribbon as it flows from the lake of tin, marking and counting the number of defects on the new glass. The number of defects identified by the inspectors for a -hour period is shown below

you divide the cost ($15) by the quantity (6) to get your questions answer. the yo-yo costs $2.50. hope this : )!

step-by-step explanation:

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
