Joe calls a landscaping business who tells him they charge a flat rate of $60 per day for landscaping plus $40 for every fruit tree planted. if joe has to spend less than $250 for landscaping, how many trees can joe get planted?

2 trees

40 x 2 = 80

60 x 2 = 120

120 + 80 = 200

it would go over his budget it he planted 3.

answer: '

the distance between points l and m

step-by-step explanation:

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.
