Answer:
9 Adults
Step-by-step explanation:
20children=15adults
12children=?
You cross-multiply so as to get how many adults
<u>12 x 15</u> = <u>180</u>
20 20
=9 adults in the elevator
Answer:
π x³ /12 is the volume of the cone if A cone has a height of x and a diameter of x
Step-by-step explanation:
The base diameter and the height of a cone are both equal to x units
Diameter of cone = x units
Radius = Diameter /2
=> Radius of cone = x/2 units
Height of cone =x units
Volume of cone = (1/3) π r²h
r = radius h = height
=> Volume of cone = (1/3)π (x/2)² * x
= (1/3) π (x²/4) * x
= (1/12) π x³
= π x³ /12 cubic units
The value of inverse function when x = 0 is 1, when x = 1 is infinity or not defined, and when x = 3 is -1/2.
What is function?
A function in mathematics is an expression, rule, or law that determines the relationship between two variables, one of which is independent, and the other of which is dependent (the dependent variable). The traditional notion of function was first proposed by German mathematician Peter Dirichlet in 1837.
The function for the line shown in the graph can be written as:
y = -x + 1
Here, y = f(x)


We can put the given values in place of x in this function:

or ( not defined)

This is the required answers.
