If quarterly payments are made for 15 years, find the value for n in the following present value ordinary annuity formula

The value for n in the following present value ordinary annuity formula is 60.

Step-by-step explanation:

We know that,

Where,

PV = Present value of annuity,

P = Periodic payment,

r = Rate of interest per period,

n = Number of period.

As here the payment is made in each quarter i.e 4 times a year for 15 years.

So number period or n in this case will be,

Therefore, the value for n in the following present value ordinary annuity formula is 60.

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)

51

step-by-step explanation:

73-22=51 the   mass number minus the amount of protons gives you the amount of neutrons
