Answer:

Suppose we have a random number A.

The multiplicative inverse of A is a number X such that:

A*X = 1

When we work with real numbers, X = 1/A

Then:

A*(1/A) = A/A = 1

This means that (1/A) is the multiplicative inverse of A.

Where we need to have A ≠ 0, because we can not divide by 0.

Now we want to find the multiplicative inverse of the numbers:

2: Here the inverse is (1/2) = 0.5

1/5: Here the inverse is (1/(1/5)) = (5/1) = 5

-4: Herre the inverse is (1/(-4)) = -(1/4) = -0.25

Using the standard 28/36 guidelines. what is the maximum mortgage payment allowed for someone with an annual salary of $62,550?

Alex73 [517]

The maximum mortgage payment allowed for someone with an annual salary of $62,550 is $1,459.50.

The 28/36 rule is used to calculate the amount of debt a person or a household should assume. The rule suggests that a lender's following expenses cannot be more than 28% of their monthly or annual income. They are listed as follows:

Household Expense payments
Primarily rent
Mortgage payments

While the debt payments must not exceed 36% of their income.

<h3>Calculating mortgage payment</h3>

Keeping the above rule in view, the mortgage payment is calculated by multiplying the annual salary by 28% and dividing the same by 12, to calculate the mortgage payments monthly. As shown below:

62,550 x 28% = $17,514

17,514 / 12 = $1,459.50

The maximum mortgage payment allowed is $1,459.50

Derivative Rule [Product Rule]: $\displaystyle \frac{d}{dx} [f(x)g(x)]=f'(x)g(x) + g'(x)f(x)$

Step-by-step explanation:

<u>Step 1: Define</u>

<u /> $\displaystyle l = 10 \ meters$ <u />

<u /> $\displaystyle \frac{dl}{dt} = 4 \ m/day$ <u />

<u /> $\displaystyle w = 23 \ meters$ <u />

<u /> $\displaystyle \frac{dw}{dt} = 1 \ m/day$ <u />

<u />

<u>Step 2: Differentiate</u>

[Area of Rectangle] Product Rule: $\displaystyle \frac{dA}{dt} = l\frac{dw}{dt} + w\frac{dl}{dt}$

<u>Step 3: Solve</u>

[Rate] Substitute in variables [Derivative]: $\displaystyle \frac{dA}{dt} = (10 \ m)(1 \ m/day) + (23 \ m)(4 \ m/day)$
[Rate] Multiply: $\displaystyle \frac{dA}{dt} = 10 \ m^2/day + 92 \ m^2/day$
[Rate] Add: $\displaystyle \frac{dA}{dt} = 102 \ m^2/day$
