Thank you for posting your question here at brianly. I hope the answer will help you. Below is the solution:
or segment from (4,0) to (-4,0), y is always zero because straight segment.
<span>in that case x*y=x*0=0 </span>
<span>and x+y=x+0=x </span>
<span>if you choose x=4-t where t goes from 0 to 8 you should get </span>
<span>r(t)=0i+(4-t)j </span>
Answer:
175 ways
Step-by-step explanation:
5 balls are red, and 7 balls are blue making a total of 12 balls.
4 balls are drawn from the box,
1 ball is red and 3 balls are blue out of the 4 drawn from the box.
We have to choose 1 ball from 5 red balls and 3 blue balls from 7 blue balls.
Since the order is not essential we use combinations to find out
5C1 * 7C3= 5*35 = 175 ways
The value for r = - 0.8535 , there is strong correlation between the variables.
<h3>What is a correlation coefficient ?</h3>
Correlation coefficient describes the relationship between the two variables in the data .
The data given is
(1, 7), (2, 5), (3, -1), (4, 3), (5, -5)
Assuming Linear Regression ,
The data is plotted on the graphing calculator
The value for r = - 0.8535
as the value is in the range of - .85 to -1 , therefore there is strong correlation between the variables.

Answer:
The function f(x) has a vertical asymptote at x = 3
Step-by-step explanation:
We can define an asymptote as an infinite aproximation to given value, such that the value is never actually reached.
For example, in the case of the natural logarithm, it is not defined for x = 0.
Then Ln(x) has an asymptote at x = 0 that tends to negative infinity, (but never reaches it, as again, Ln(x) is not defined for x = 0)
So a vertical asymptote will be a vertical tendency at a given x-value.
In the graph is quite easy to see it, it occurs at x = 3 (the graph goes down infinitely, never actually reaching the value x = 3)
Then:
The function f(x) has a vertical asymptote at x = 3
