Artist 52 [7]2 years ago
6 0

Answer:

305 and 793

Step-by-step explanation:

LCM * HCF = product

3965 * 61 = 241,865 = 5*13*61*61

HCF = 61 so

61*5 = 305

61 * 13 = 793

Let f(x)= 7x-13.find f powered to the negative 1 power (x)
Reil [10]
Let f(x) be y so you have
y=7x-13
Reverse the signs of x and y so you have
x=7y-13
And then find the value of y
x+13=7y
(x+13)/7=y
And change y to f(x)-1

Describe the effect an increase in i, the interest rate applied to the present value, has on the monthly payment P in the formul
Setler79 [48]

The A option is correct.

<h2>Ratio and proportion</h2>

A ratio is an ordered pair of numbers a and b, written as a/b where b does not equal 0. A proportion is an equation in which two ratios are set equal to each other.

Given

The interest rate applied to the present value has on the monthly payment P in the formula

\rm P = PV(\dfrac{i}{1-i})^{-n}

<h3>To find </h3>

The effect an increase in i.

<h3>How to find it?</h3>

\rm P = PV(\dfrac{i}{1-i})^{-n}\\

on simplifying the equation, we get

\rm P = PV(\dfrac{i}{1-i})^{-n}\\\\P = PV\dfrac{1}{(\frac{i}{1-i})^n}\\\\\\P = PV(\dfrac{1-i}{i})^{n}\\\\P = PV(\dfrac{1}{i} - 1)^{n}

Let n be the constant, then the equation will be

\rm P = PV(\dfrac{1}{i} - 1)^{n}\\\\\dfrac{1}{V} \propto \dfrac{1}{i}\\\\V \propto i

It is clear that V is proportional to i.

An increase in i, the interest rate, will not change P, the monthly payment.

Thus, the A option is correct.

More about the ratio and the proportion link is given below.
