Answer:
Inversely proportion states that a relationship between two variables in which the product is a constant.
If one of the variable increases, then the other decreases in proportion so that the product is unchanged.
If y is inversely proportional to x, then the equation is of the form
; where k is the constant proportionality.
As per the given condition: Speed of a car is inversely proportional to the time it takes to complete a 100 mile trip,
Let x represents the speed of car and y represents the time taken.
From the given condition:
Then by definition of inversely proportional;
[Since,
]
Here, k represents the distance(i.e constant) = 100 miles.
therefore, the equation becomes now;
or
xy = 100
The following graph for the above equation as shown below :
Answer:
The x -coordinate(s) of the point(s) of intersection of these two polynomials are
The sum of these x -coordinates is
Step-by-step explanation:
The intersections of the two polynomials, p(x) and q(x), are the roots of the equation p(x) = q(x).
Thus, and we solve for x
Using Zero Factor Theorem: = 0 if and only if = 0 or = 0
The solutions are:
The sum of these x -coordinates is
We can check our work with the graph of the two polynomials.
Answer:
Step-by-step explanation:
let y=ab^x
x=0,y=18
18=ab^0=a
a=18
y=18b^x
when x=2,y=1152
