3 0

360 divided by x = 21.2 recurring
So rearrange that to get x = 360 divided by 21.2
Which rounds up to 17

a rectangular prism is 5 meters long, 17 meters wide, and 4 meters high. what is the surface area of the rectangular prism?

Mars2501 [29]

The surface area of rectangular prism is 346 square meters.

Given the figure is rectangular prism.

We know that the surface area of rectangular prism with length L, width W and height H is = 2(LW+WH+LH)

Given that the length of prism = 5 m

Width of prism = 17 m

Height of prism = 4 m

So the total surface area of the rectangular prism is given by,

= 2 [5*17 + 17*4 + 4*5]

= 2 [85 + 68 + 20]

= 2*173

= 346 square meters

Hence the surface area of rectangular prism is 346 square meters.

Answer:

Following are the solution to the given point:

Step-by-step explanation:

Please find the comp[lete question in the attached file.

Given:

$\bold{ \lim_{n \to \ \infty} (1+ \frac{r}{n})^{nt} =e^{rt}}$

In point 1:

$\to y = (1+ \frac{r}{n})^{nt}$

In point 2:

$\to \ln (y)= nt \ln(1+ \frac{r}{n})$

In point 3:

Its key thing to understand, which would be that you consider the limit n to $\infty$ , in which r and t were constants!

$=lim_{n \to \ \infty} \ln (y) = lim_{n \to \ \infty} nt \ln(1+\frac{r}{n})\\\\= lim_{n \to \ \infty} \frac{\ln(1+\frac{r}{n})}{\frac{1}{nt}}\\\\= lim_{n \to \ \infty} \frac{\frac{-r}{\frac{n^2}{(1+\frac{r}{n})}}}{- \frac{1}{n^2t}}\\\\= lim_{n \to \ \infty} \frac{\frac{rn^2t}{n^2}}{(1+\frac{r}{n})}\\\\= lim_{n \to \ \infty} \frac{rt}{(1+\frac{r}{n})}\\\\= \frac{rt}{(1+\frac{r}{0})}\\\\=rt$
