Answer:
50 
Step-by-step explanation:
take the arc degrees (100) and divide by 2 
Inscribed angles are 1/2 of the created arc degrees 
 
        
                    
             
        
        
        
Answer:
0.08, or 8%
Step-by-step explanation:
The appropriate formula is i = p*r*t, where p is the principal, r is the interest rate as a decimal fraction, and t is the time in years.
We want to calculate r when i, p and t are known.
                                                            i
Solving i = p*r*t for r, we get r = ------------
                                                        p*t
The interest rate in this case is
         $1600
r = ---------------- = 0.08, or 8%
       $5000*4
 
        
             
        
        
        
Answer:
 
 
Step-by-step explanation:
Let's use the definition of the Laplace transform and the identity given:![\mathcal{L}[t \cos 5t]=(-1)F'(s)](https://tex.z-dn.net/?f=%5Cmathcal%7BL%7D%5Bt%20%5Ccos%205t%5D%3D%28-1%29F%27%28s%29) with
 with ![F(s)=\mathcal{L}[\cos 5t]](https://tex.z-dn.net/?f=F%28s%29%3D%5Cmathcal%7BL%7D%5B%5Ccos%205t%5D) .
. 
Now,  . Using integration by parts with u=e^(-st) and dv=cos(5t), we obtain that
. Using integration by parts with u=e^(-st) and dv=cos(5t), we obtain that  .
.
Using integration by parts again with u=e^(-st) and dv=sin(5t), we obtain that
  .
.
Solving for F(s) on the last equation,  , then the Laplace transform we were searching is
, then the Laplace transform we were searching is
