Answer: 90 degrees, 43 minutes, 16 seconds

Step-by-step explanation: To convert from decimal degrees to degrees minutes and seconds, the whole number part which is 90 is the degree, then multiplying the decimal part (0.721) by 60 gives the minutes which is 43 and finally multiplying the remaining decimal (0.26) by 60 gives the seconds which is approximately equal to 16

Find an equation of the largest sphere with center (8, 2, 9) that is contained in the first octant.
Furkat [3]
The point (8,2,9) is in the first octant.
The closest distance from the coordinate planes is the value y=2, which will therefore be the maximum radius of the required sphere.

The standard equation of a sphere with radius r and centre (u,v,w) is given by
(x-u)^2+(y-v)^2+(z-w)^2=r^2

Substituting r=2, u=8, v=2, w=9, we get the equation of the required sphere
(x-8)^2+(y-2)^2+(w-9)^2=2^2

seropon [69]

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

In point 4:

\to \lim_{n \to \ \infty} = (1+\frac{r}{n})^{nt} and

\to \lim_{n \to \ \infty} = A_0e^{rt}

What are the variables X, Y, and Z?
posledela
Tan(30°) = 17/x
x = 17/tan(30°) = 17√3

The hypotenuse of the smaller triangle is as you show, 34.

sin(45°) = 34/y
y = 34/sin(45°) = 34√2

x = 17√3
y = 34√2
