Answer:   D) (x + 3)² + (y + 5)²  = 16
<u>Step-by-step explanation:</u>
The equation of a circle is: (x - h)² + (y - k)² = r²    
where (h, k) = center   and    r = radius
Given: (h, k) = (-3, -5)  r = 4
Equation: (x - (-3))² + (y - (-5))² = 4²
                  (x + 3)²  +  (y + 5)²  = 16
 
        
             
        
        
        
D=25m+50
D=(25)(8)+50
D=200+50
D=250
There will be $250 after 8 months.
 
        
                    
             
        
        
        
Answer:
56 meters.
Step-by-step explanation:
Please find the attachment.
Let the leaning tower's be h meters tall, when it was originally built.
We can see from our attachment that the side with length 55.86 meters is hypotenuse and h is adjacent side for 4 degree angle.
Since we know that cosine relates the adjacent and hypotenuse of a right triangle.

Upon substituting our given values we will get,



 
                      
Therefore, the leaning tower was approximately 56 meters, when it was originally built.
 
 
        
             
        
        
        
Answer:
5000 meters
Step-by-step explanation:
1 km = 1000 m
5 km = 1000 × 5 = 5000 meters 
Therefore there are 5000 meters in a 5 km race.
