Answer:
Ordinary annuity 
Step-by-step explanation:
Given : ABC Insurance offers an annuity with 4.5% APR for the next 5 years. You decide to invest $1000 each year into this account.
To find : What type of annuity is this?
Solution :
Annuity is the form of insurance in which some of the money is paid each year to secure for future.
There are two types of annuity:
Ordinary annuity - In this annuity the payment is made at the end of each period  over a fixed length of time. Also in this annuity payments are made monthly, quarterly, semi-annually or annually. 
Annuity due - is the opposite of ordinary annuity as in this the payment is made at the beginning of each period.
In the given situation the annuity is ordinary annuity because the investment is done each year for 5 years. 
 
        
                    
             
        
        
        
6 songs
The way to find this answer is to divide 18 by 3, which is six, which means that after every six songs a commercial is played. 
Hope this was helpful and that I explained it correctly. 
        
             
        
        
        
At every 1.0 unit, boiling point decreases 1.8 unit, which means the slope m = -1.8.
        
             
        
        
        
Answer:
- arc BF = 76°
- ∠M = 31°
- ∠BGE = 121°
- ∠MFB = 111°
Step-by-step explanation:
(a) ∠FBM is the complement of ∠FBC, so is ...
   ∠FBM = 90° -52° = 38°
The measure of arc BF is twice this angle, so is ...
   arc BF = 2∠FBM = 2(38°)
   arc BF = 76°
__
(b) ∠M is half the difference between the measures of arcs BE and BF, so is ...
   ∠M = (1/2)(138° -76°) = 62°/2
   ∠M = 31°
__
(c) arc FC is the supplement to arc BF, so has measure ...
   arc FC = 180° -arc BF = 180° -76° = 104°
∠BGE is half the sum of arcs BE and FC, so is ...
   ∠BGE = (1/2)(arc BE +arc FC) = (138° +104°)/2
   ∠BGE = 121°
__
(d) ∠MFB is the remaining angle in ∆MFB, so has measure ...
   ∠MFB = 180° -∠M -∠FBM = 180° -31° -38°
   ∠MFB = 111°
