Answer:
Cost, C = $28410.72
Step-by-step explanation:
We have, a concrete pillar has the shape of a cylinder.
Diameter of pillar is 8 m and ts height is 9 m
If concrete costs $87 per cubic meter, it is required to find the concrete cost for the pillar. For this lets find the area of cylindrical shape. So,
The cost of pillar at the rate of $87 per cubic meter will be :
<h2>Answer:</h2>
A function from a set
to a set
is a relation that assigns to each element
in the set
exactly one element
in the set
. The set
is the domain (also called the set of inputs) of the function and the set
contains the range (also called the set of outputs). On the other hand, a function has an inverse function if and only if passes the Horizontal Line Test for Inverse Functions. This test tells us that a function
has an inverse function if and only if there is no any horizontal line that intersects the graph of
at more than one point. So the function is called one-to-one. The graph of
is shown below. As you can see, this function does not pass the Horizontal Line Test, therefore the inverse is not a function. However, let's find
:
and this is not a function because there are elements in the set of inputs that match with two elements in the set of outputs.
