Answer:
Fundamental theorem of algebra, rational root theorem, Descartes rule of signs, remainder theorem, and the factor theorem can be utilized in solving polynomials and their depressed equations.
Polynomial functions can be written when given the zeros by determining the factors of the function, and multiplying the factors.
X-y=200
xy=mn
so
first equation times -1 and add x both sides
y=x-200
sub that for y in other equation
x(x-200)=min
x²-200x=min
take deritivive
2x-200=min
find where it equals 0
2x-200=0
2x=200
x=100
y=x-200
y=100-200
y=-100
the numbers aer 100 and -100
He is incorrect because since 0.029 is in the thousandths place the fraction would be written as 29/1000
Answer:
The edge length of the shipping container is 14 in.
Step-by-step explanation:
The volume enclosed by a cube is the number of cubic units that will exactly fill a cube.
To find the volume of a cube we need to recall that a cube has all edges the same length. The volume of a cube is found by multiplying the length of any edge by itself twice. Or as a formula:
where, <em>s</em> is the length of any edge of the cube.
To find the edge length of the shipping container we use the fact that the volume of a cube shaped shipping container is 2744 in³ and the above formula.
The student's measurement was off by an absolute error of
|2.9 cm - 2.6 cm| = 0.3 cm
The percent error in the measurement is the absolute error divided by the actual length of the string,
(0.3 cm) / (2.9 cm) ≈ 0.103 = 10.3%
