I have £150 in a bank account. I get 5% interest a year. How much will I have at the end of the year?

£157.5

Step-by-step explanation:

To solve this problem, we simply multiply £150 by 5% and then add the sum to £150 to get the answer. Remember that we need to put 5% into the decimal form (5% -> 0.05).

£150 x 0.05 = 7.5

Now we can add 7.5 to £150.

£150 + 7.5 = £157.5

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.

what's the question here?
