What is the correct inverse function for f(x) = e2x ?

Lena [83]

To solve this problem you must appy the proccedure shown below:

1. You have the following function given in the problem above:

f(x)=e^2x

2. You can rewrite is:

y=e^2x

3. Interchange the variables, as below:

x=e^2y

3. The inverse of an exponential function is the logarithm function. Thereforem you have:

ln(x)=ln(e^2y)
ln(x)=2y

4.Then, you have:

y=ln(x)/2

Therefore, the answer is:

f^-1(x)=ln(x)/2

11. Twyla and Tony have a 30/5 balloon mortgage for $389,900 with a rate of 4.85%. How much will they pay in interest over the l

kykrilka [37]

Answer:

Explanation:

Twyla and Tony with a balloon mortgage of 30/5 will make constant payments over the space of 5 years and then complete the bulk balloon payment for 25 years remaining.

Given mortgage loan value of $389900

Interest rate of 4.85%

We are asked to calculate the interest over the life of the loan.

We will calculate interest by calculating constant payments over the period of 5 years before balloon payment is due and adding them together then subtracting the mortgage loan given $389900

Formula for constant payments :

A= P×r×r(1+r)^n/(1+r)^n-1

Where A= constant/monthly payments

r= interest rate on the mortgage loan

n= number of payments = 30×12= 360

P= mortgage loan given

A= $389900×0.0485×0.0485(1+0.0485)^360/(1+0.0485)^360-1

=$389900×0.0485×1231340.79/25388468.94

=$389900×0.0485×0.04850

A= $917.142

Payment for five years(with interest)= $917.142×60= $55028.52

Calculate balloon payment:

FV= PV(1+r)^n - P((1+r)^n-1/r)

Where FV= future value of balloon payment

PV= initial loan given

r= interest rate on loan

n= number of payments

P= monthly payments

Substitute:

FV= $389900(1+0.0485/12)^60-917.142((1+0.0485/12)^60-1/0.0485/12)

=$389900×1.2738-917.142(0.2738/0.004041)

=$389900×1.2738-917.142×67.756

= 496654.62-62141.87

FV = $434512.75

Therefore total payment made with interest over the life of the loan= balloon payment+ constant payments for five years= $434512.75+$55028.52

Representative is paid the greater

vivado [14]

Building and solving an inequality, it is found that at a volume of sales of $11,875 he will start to earn more from the commission based compensation.

------------------------

We want to find how much in dollars he has to sell such that 8% of this amount is greater than $950.
Supposing he sells $x, 8% of this is represented by 0.08x. We want it to be greater than $950, thus, the inequality is:

$0.08x > 950$

Now we solve the inequality, similarly to how we would solve an equality.

$x > \frac{950}{0.08}$

$x > 11875$

At a volume of sales of $11,875 he will start to earn more from the commission based compensation.
