Answer:
B
Step-by-step explanation:
tan45° = 10/x
=> 1 = 10/x
=> x = 10
=> y^2 = 10^2 + 10^2 = 200
=> y = 100*sqrt(2)
=> b
<em>At x = -3 is located a hole. </em>
<h2>
Explanation:</h2>
In this problem, we have the following function:

A hole will lie at the x-values that makes the function undefined, that is, when the denominator is zero. In a mathematical language:

From this equation, we get two solutions:

At those x-values the function will have a hole. From the choices:
<em>At x = -3 is located a hole. </em>

Answer:
All real values of x where x < −1
Step-by-step explanation:
Solve the function as an inequality:
(x-3)(x+1)>0
There are two cases in this:
Both factors are greater than 0.
x-3>0 and x+1>0
x>3 and x>-1
The intersection is x >3
OR
Both factors less than 0.
x-3<0 and x+1<0
x< 3 and x<-1
The intersection is x< -1
We have obtained that the function is positive for the intervals x < -1 and x > 3. But in one of those intervals the function is decreasing and in the other is increasing.
The answer is: all real values of x where x < −1 ....
