F(n) = 900 - 60(n-1) represent the amount oscar still need to repay on a loan at the beginning of month n .find the amount oscar pays monthly and the month in which he will make his last payment.

Each installment will be of 60 and 16th will be the last payment.

Step-by-step explanation:

To find the monthly repayment by Oscar we first find the sequence.

For that first we put in

Now for

For

So the sequenxe is 900,840,780......

As the amount is decreasing by 900-840=840-780=60

Therefore each installment will be equal to 60

For last payment amount will become 0

i.e.

Last month will be 16th

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.

the median is   36 orr sum like dat
