Answer:
Radius = 6.46 meters
Height = 1.46 meters
Step-by-step explanation:
The volume of a cylinder = πr²h
In the above question, we were given
r = (x + 5) meters
h = x meters
Volume = 192 cubic meters
Hence,
192 = π × (x + 5)² × x
192 = π × (x² + 10x + 25) × x
192 = π × (x³ + 10x² + 25x)
Divide both sides by π
192/π = x³ + 10x² + 25x
61.115498147 = x³ + 10x² + 25x
x³ + 10x² + 25x - 61.12
This Quadratic equation is a polynomial
x = 1.46119
From the above:
Radius = (x + 5)meters
Radius = 1.46119 + 5 = 6.46119 meters
Approximately to 2 decimal places = 6.46 meters
Height = x meters
Height = 1.46119 meters
Approximately to 2 decimal places = 1.46 meters
Answer:
1)A parabola is defined as a set of points in a plane which are equidistant from a straight line or directrix and focus.
The hyperbola can be defined as the difference of distances between a set of points, which are present in a plane to two fixed points is a positive constant.
2)A parabola has single focus and directrix
A hyperbola has two foci and two directrices
3)Eccentricity, e = 1(parabola)
Eccentricity, e>1(hyperbola)
4)The two arms present in a parabola should be parallel to each other
The arms present in hyperbola are not parallel to each other
5)It has no asymptotes(parabola)
It has two asymptotes(hyperbola)
Answer:
Step-by-step explanation:
x + 6 = 0
x = -6
-x + 1 = 0
-x = -1
x = 1
x = -6, 1
You can't the answer is 2 because 20 goes into 10 twice
