$n^{16}$ and 9 are the squares of, respectively, $n^8$ and 3.

So, using

$a^2-b^2=(a+b)(a-b)$

we have

$n^{16}-9=(n^8+3)(n^8-3)$

Determine the equation of the line with slope 3/4 passing through the point 4,0

Vitek1552 [10]

Answer:

$y = \frac{3}{4}x - 3$

Step-by-step explanation:

If it has a slope of 3/4, then it will look like this:

$y = \frac{3}{4}x + b$

If it passes through (4, 0), than y = 0 when x = 4

$y = \frac{3}{4}(4) + b$

$y = 3 + b$

$b = -3$

Therefore, the equation is $y = \frac{3}{4}x - 3$ .

The weight distribution of parcels sent in a certain manner is normal with mean value 17 lb and standard deviation 3.3 lb. The p

Yakvenalex [24]

Answer: The value of c would be 26.514 lb.

Step-by-step explanation:

Since we have given that

Mean = 17 lb

Standard deviation = 3.3 lb

At 99% level of significance, z = 2.58

So, it becomes,

$Z=\dfrac{X-\mu}{\sigma}\\\\2.58=\dfrac{X-17}{3.3}\\\\2.58\times 3.3=X-17\\\\8.514+17=X\\\\X=25.514$

So, the weight c would be

$c=25.514+1\\\\c=26.514$

Hence, the value of c would be 26.514 lb.

Which is the graph of the following equation?

lesantik [10]

Given equation is

$\frac{(x-5)^2}{16} - \frac{(y-2)^2}{9}=1$

The given equation is in the form of

$\frac{(x-h)^2}{a^2} - \frac{(y-k)^2}{b^2}=1$

a^2= 16 , so a=4

b^2 = 9 so b= 4

The value of 'a' is greater than the value of 'b'

So it is a Horizontal hyperbola

First two graphs are horizontal hyperbola

Here center is (h,k)

h= 5 and k =2 from the given equation

So center is (5,2)

Now we find vertices

Vertices are (h+a,k) and (h-a,k)

We know h=5, k=2 and a=4

So vertices are (9,2) and (1,2)

Second graph having same vertices and center

The correct graph is attached below
