Answer:
10.56825
Step-by-step explanation:
solution:
4.95×2=9.9
9.9×6.75%=0.66825
0.66825+9.9=10.56825
 
        
             
        
        
        
The midpoint of a segment divides the segment into equal halves
The other endpoint is 1- 5i
<h3>How to determine the missing endpoint </h3>
The coordinates are given as:
Point 1: 7 + i
Midpoint: 3 - 2i
Represent the other endpoint with x.
So, we have:
2 * Midpoint = Point 1 + x
This gives


Collect like terms

Evaluate the like terms

Hence, the other endpoint is 1- 5i

Answer: z=8
Step-by-step explanation:
9z-3z=48
     6z=48 ⇔ combine like terms
       z=8

Answer:
we have (a,b,c)=(4,-2,0) and R=4 (radius)
Step-by-step explanation:
since
x²+y²+z²−8x+4y=−4
we have to complete the squares to finish with a equation of the form
(x-a)²+(y-b)²+(z-c)²=R² 
that is the equation of a sphere of radius R and centre in (a,b,c)
thus
x²+y²+z²−8x+4y=−4
x²+y²+z²−8x+4y +4 = 0
x²+y²+z²−8x+4y +4 +16-16 =0
(x²−8x + 16) + (y² + 4y + 4 ) + (z²) -16 = 0
(x-4)² + (y+2)² + z² = 16
(x-4)² + (y-(-2))² + (z-0)² = 4²
thus we have a=4 , b= -2 , c= 0 and R=4
 
        
             
        
        
        
Im assuming you meant the 9th term and thats 47
