Answer:
Step-by-step explanation:
If the polynomial function has zeros at 9 with multiplicity 1, then is a factor of the polynomial.
Also if the polynomial function has a zero at with a multiplicity of 2, then
is another factor of the polynomial.
The polynomial function can therefore be written as;
But the given polynomial has an value of 2, hence the required polynomial is
The value of x is 3.
Solution:
Length of the top rectangle = x ft
Width of the top rectangle = x ft
Height of the top rectangle = 3x ft
Volume of the top rectangle
Volume of the top rectangle cubic feet
Length of the bottom rectangle = ft
Width of the bottom rectangle = ft
Height of the bottom rectangle = 0.5 ft
Volume of the bottom rectangle
Volume of the bottom rectangle cubic feet
Total concrete for both pieces = 90 cubic feet.
Volume of top + volume of bottom = 90 cubic feet
Solve by factoring.
x = 3,
Solve using quadratic formula,
Ignore the complex roots.
The value of x is 3.
