Answer:20 cm
Step-by-step explanation:
Volume of cone=540π
Radius=r=9
Volume of cone=1/3 x π x r^2 x h
540π=1/3 x π x 9^2 x h
540π=1/3 x π x 9 x 9 x h
540π=(1xπx9x9xh)/3
540π=(81πh)/3
540π=27πh
Divide both sides by 27π
540π/27π=(27πh)/27π
20=h
h=20
Height =20 cm
The angle β (see the figure) so that the cone will have a volume of 60 in3 is 82.05 degrees
The formula for calculating the volume of a cone is expressed as:
V = 1/3πr²h
where
r is the radius
h is the height
Given the following
volume = 60
radius = 2
h = r tanβ
Substitute
V = 1/3πr²(r tanβ)
Substitute
60 = 1/3(3.14)(2)³tanβ
180 = 25.12tanβ
tanβ = 180/25.12
β = 82.05 degrees
Hence the angle β (see the figure) so that the cone will have a volume of 60 in3 is 82.05 degrees

Answer:
"Descartes' rule of sign is used to determine the number of real zeros of a polynomial function. It tells us that the number of positive real zeroes in a polynomial function f(x) is the same or less than by an even numbers as the number of changes in the sign of the coefficients."

The Rational Root Theorem provides possible rational roots of a polynomial while Descartes' Rule of Signs indicates the number of positive and negative roots of a polynomial. They both serve as crucial tools in understanding and solving polynomial equations.
The Rational Root Theorem and Descartes' Rule of Signs are both mathematical tools that can provide valuable information about the zeros (or roots) of a polynomial. The Rational Root Theorem can help us determine the possible rational roots of a polynomial equation. It states that if a polynomial has a rational root p/q (where p and q are relatively prime), then p is a factor of the trailing constant and q is a factor of the leading coefficient.
On the other hand, Descartes' Rule of Signs gives us an indication of the number of positive and negative real roots in a polynomial. It does this by considering the number of sign changes in the coefficients of the terms of the polynomial when arranged in descending power.
For example, in the polynomial + 2x - 6, by applying Descartes' Rule of Signs, we can infer there are two or zero positive roots (since there are two sign changes) and one negative root (since there are no sign changes when the terms are arranged in ascending power).
