Answer:
± 60
Step-by-step explanation:
aₙ = a₁ * rⁿ⁻¹
a₇ = 30 = a₁ * r⁷⁻¹ = a₁ * r⁶     (1)
a₅ = 120 = a₁ * r⁵⁻¹ = a₁ * r⁴     (2)
(1)/(2): 30/120 = 1/4 = r²
r = ± 1/2   or ± 0.5
a₁ = a₇/r⁶ = 30/0.5⁶ = 1920
a₆ = 1920 * (± 1/2)⁶⁻¹ = 1920 * ± 1/32 = ± 60
 
        
             
        
        
        
Answer:
2.25 Years
Step-by-step explanation:
We know that a year has 12 months.  So,  .  We add this to 2 to get 2.25.
.  We add this to 2 to get 2.25.
 
        
                    
             
        
        
        
Since the volume of a rectangular prism is V=lwh, we can isolate for h to obtain that h=V/(lw).
So, for the first prism, the height is 117/(4*6.5) = 4.5
Similarly, for the second prism, the height is 175.5/(6.5 * 4) = 6.75
So, the difference in heights is 6.75-4.5=2.25 = 2 1/4 inches

Therefore, the coordinates of point 'b' would be (-0.5 , 4.75).
Step-by-step explanation:
We have been given that point a is at   (-2,4) and point c is at   (4,7) . 
We are asked to find the coordinates of point b on segment ac such that the ratio is 1:3.
We will use section formula to solve our given problem.
When point P divides a segment internally in the ratio m:n, the coordinates of point P would be:
