the square root of 81 is 9
 
        
                    
             
        
        
        
For this case we have the following line:
 x = 4
 The first thing you should know is that the slope of the line is given by:
 m = (y2-y1) / (x2-x1)
 In this case:
 x2 = x1
 Thus,
 The slope is:
 m = (y2-y1) / (0)
 m = infinity
 Answer:
 The slope of the line is:
 m = infinity
        
                    
             
        
        
        
Answer:
x^2-6x, 4x^2-1x,10x^2+8x,15x^2-3xy
Just use the distributive property like you have before and you will get these answers, Hope this helped!
 
        
                    
             
        
        
        
Answer:
$1,600
Step-by-step explanation:
To find out how much of the final balance will come from the interest earned, you have to determine the total value of the deposits made and subtract this from the balance the account will have after 5 years.
amount deposited each month: $175
months: 12*5= 60
Total amount deposited: $175*60= $10,500
Interests: $12,100-$10,500= $1,600
According to this, the amount of the final balance that will come from the interest earned is $1,600.
 
        
             
        
        
        
Mean, x_bar = 1518
Standard deviation, sigma = 325
Range required: 1550 ≤ X ≤ 1575
Z = (X - x_bar)/sigma
Z1 = (1550-1518)/325 ≈ 0.1
Z2 = (1575-1518)/325 ≈ 0.18
From Z tables,
P(Z1) = 0.5398
P(Z2) = 0.5714
P(1550≤X≤1575) = P(Z2) - P(Z1) = 0.5714 - 0.5398 = 0.0316
The correct answer is C.
