Hello.

e is a mathematical constant, and it's like pi, it's irrational. It's approximately equal to 2.71828....

So, $e^{\frac{3}{2}} = 4.4816...$
It's approximately equal to 4.5 which is choice 2.

Find the derivative of f(x) = negative 9 divided by x at x = -4. (6 points) 4 divided by 9 16 divided by 9 9 divided by 16 9 div

Len [333]

Answer:

9/16

Step-by-step explanation:

$f(x)=-\frac{9}{x}$

$f(x)=-9x^{-1}$

Derivative rule:

$f(x)=x^{n} \\$

$\frac{df}{dx}=nx^{n-1}$

Here, n=-1, so

$\frac{df}{dx}=(-9)(-1)x^{-2} =\frac{9}{x^{2} }$

Evaluating this at x=-4 gives 9/16

Jacey obtains a 30-year 6/2 ARM at 4% with a 2/6 cap structure in the amount of $224,500. What is the monthly payment during the

beks73 [17]

In this case we have an ARM fixed for 6 years and adjust after the initial first 6 years every 2 years after. The basic idea behind a ARM is that the interest changes periodically, but since our ARM is fixed for 6 years, our going to calculate the monthly payment during the initial period using the formula: $m= \frac{P( \frac{r}{12}) }{1-(1+ \frac{r}{12})^{-12t} }$
where
$m$ is the monthly payment
$P$ is the amount
$r$ is the interest rate in decimal form
$t$ is the number years

First we need to convert our interest rate of 4% to decimal form by dividing it by 100%:
$\frac{4}{100} =0.04$
We also know from our question that $P=224500$ and $t=30$ , so lets replace those values into our formula to find the monthly payment:
$m= \frac{224500( \frac{0.04}{12}) }{1-(1+ \frac{0.04}{12})^{-(12)(30)} }$
$m=1071.80$

We can conclude that the monthly payment during the initial period is $1071.58
