Answer:
72
Step-by-step explanation:
80x.90= 72
Answer:
The y-intercept is 0
Step-by-step explanation:
Here, we want to get the y-intercept value of y = sin x
From the plot of the graph, we can see that the graph of sin x touches the y-axis at the point y = 0
So therefore, the y-intercept of y = sin x is 0
The general form for a circle centered at (a,b) with radius r is
(x - a)² + (y - b)² = r²
Comparing to our form we have a = -3, b=4, r²=25 so r=5
Answer: Center (-3,4) radius 5
<h2>Here's the Solution to this Question</h2>
Given A 

A relation is a function when every element of set A has image in B and a element of set A can-not have more than one image in set B.
So, Relation
is a function.
(c) Given
is a real valued function defined by
.
(I) Function is defined for all real values of
. Hence,
Domain of 
(ii) Now, as

Hence, Range of f=[−9,∞)
(iii) Representation of
as a set of ordered pair =
