Y1=2/3x , Y2=2/3x-2
those are the graph of the functions
 
        
             
        
        
        
Answer:
1.5
Step-by-step explanation:
The Euler's method is a common approximation method for the solution of differential equations. It can be used to obtain an approximate value of a given function. The Euler's formula is:

Therefore, n =1 will give:

h is the step size and it is equivalent to 


 
        
             
        
        
        
5. a^2 + b^2 = c^2...where a and b are the legs and c is the hypotenuse
    7^2 + 10^2 = c^2
    49 + 100 =c^2
    149 = c^2....take square root of both sides, eliminating the ^2
     sq rt 149 = c
     12.21 = c.....so the approximate length of 3rd side is 12 m
6. x = number of books bought
7. m < 2 + m < 8 = 180
8. 1000 = 400 + 24x
     1000 - 400 = 24x
     600 = 24x
     600/24 = x
     25 = x <=== 25 months he will have spent $ 1000
