Answer: 
Step-by-step explanation:
Alright, lets get started.
The given expression is given as :

We know quotient identity as :

Similarly, we know reciprocal identity as :

lets plug the value of cot and sec in given expression

cos will be cancelled, remaining will be 

Using reciprocal identity again, that will equal to :

Step-by-step explanation:
3.14 divided by 28.26 = 9
 
        
             
        
        
        
Answer:
 <em>y = - </em> <em> x + 3 </em>
<em> x + 3 </em>
Step-by-step explanation:
y = mx + b 
m =  and "b" is y-intercept with coordinates (0, b)
 and "b" is y-intercept with coordinates (0, b) 
(0, 3) ⇒ <u><em>b = 3</em></u> 
(4, 1), (6, 0) 
m =  = -
 = -  
 
<em>y = - </em> <em> x + 3</em>
<em> x + 3</em> 
 
        
             
        
        
        
First, you've got to figure out the value of the radius so divide the diameter by two. Then, you'll want to find the area of the base or pi times radius squared. 
(3.14x3^2)x9=V 
After doing the math your answer comes out to 254.34 cubic feet or feet^3
        
             
        
        
        
Answer:
Option A
Step-by-step explanation:
for right angle triangle a²+b²= c²
60²+80²= 10000
√10000= 100
