Answer:
the second one 
Step-by-step explanation:
 
        
                    
             
        
        
        
From trigonometry we know that: 
if 
then,  (where
 (where  is an integer)
 is an integer)
This can be rewritten in degrees as:
 .............(Equation 1)
.............(Equation 1)
Now, in our case, 
Therefore, (Equation 1) can be written as:
 ..........(Equation 2)
..........(Equation 2)
Now, to find the correct options all that we have to do is replace n by relevant integers and find the values of  that match.
 that match.
For n=2, (Equation 2) gives us:  .
.
Thus, 
Now, we know that: 
Let n=-1, then:

Thus, 
Likewise, 
Only the last option  will never match
 will never match  because no integral value of
 because no integral value of  will ever give
 will ever give 
Thus the last option is the correct option.
 
        
                    
             
        
        
        
Answer:
The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).

Alliteration 
how I remember is that the 2 L’s are together in the word, and the same letter is repeated in the sentence. 
if that makes sense,
hope i’m not too late!!
        
                    
             
        
        
        
Ts temperature as a function of time is given by T(t)=a(1-e^kt)+b
the values of a and b area = 50 Fb = 350 F
this is very evident to equation the b is the initial temperatre of the oven which is 350 F
and also a is the initial temperature of the potato because it is the term multiplied by the exponent term which will indicate the temperature increasse of the potato
