The next two terms of the sequence are 96 and 192. And the formula for the nth term of the sequence is [tex]T_{n+1} = 2T_{n}[/tex].
According to the given question.
We have a sequence 3, 6, 12, 24, 48, ..
Since, the first term of the sequence is 3.
The second term of the sequence is 6.
The third term of the sequence is 12.
Here, we can say that the next term is twice the previous term.
So, the next two terms of the given sequence, i.e.
Sixth term = 48 × 2 = 96
Seventh term = 96 × 192
Therefore, the formula for the nth term of the sequence is given by
[tex]T_{n+1} = 2T_{n}[/tex].
Hence, the next two terms of the sequence are 96 and 192. And the formula for the nth term of the sequence is [tex]T_{n+1} = 2T_{n}[/tex].

Now multiply the values to get 14,918,904,000. That is almost 15 billion passwords.
That is a lot of passwords! How many passwords would the website have if users were allowed to reuse the letters and numbers? (Enter the number of successful outcomes in each of the blanks below. Let the first six spaces represent letters and the last two spaces represent numbers)
Someone please help me!!
Using the Fundamental Counting Theorem, it is found that the website would have 30,891,577,600 passwords.
What is the Fundamental Counting Theorem?It is a theorem that states that if there are n things, each with [tex]n_1, n_2, \cdots, n_n[/tex] ways to be done, each thing independent of the other, the number of ways they can be done is:
[tex]N = n_1 \times n_2 \times \cdots \times n_n[/tex]
For this problem, the first six spaces of the password are letters, and each can assume 26 values, hence the parameters are:
[tex]n_1 = n_2 = n_3 = n_4 = n_5 = n_6 = 26[/tex]
The last two spaces are composed by digits, and each can assume 10 values, hence the parameters are:
[tex]n_7 = n_8 = 10[/tex]
Hence the number of possible passwords is given by:
N = 26^6 x 10² = 30,891,577,600.

a. What is the solution of the system?
Use substitution.
x-2y+z = -4
-4x+y-2z = 1
2x+2y- z = 10
By substitution, the solution of the system of equations, x - 2y + z = -4, -4x + y -2z = 1 and 2x + 2y - z = 10, is (x , y , z) = (2 , 1 , -4).
A system of equations is a set of two or more equations which includes common variables. To solve system of equations, we must find the value of the unknown variables used in the equations that must satisfy all the equations.
There are three methods that can be used to solve system of equations.
1. Elimination
2. Substitution
3. Graphing
Using substitution method, given three equations in x, y, and z,
x - 2y + z = -4 (equation 1)
-4x + y -2z = 1 (equation 2)
2x + 2y - z = 10 (equation 3)
Using the equation 1, find the value of one variable, lets say x, in terms of the other variables.
x - 2y + z = -4 (equation 1)
x = 2y - z - 4 (equation 4)
Substitute the equation 4 to equation 2 and 3 and find the value of another variable, lets say y, in terms of the other variable.
-4x + y -2z = 1 (equation 2)
-4(2y - z - 4) + y -2z = 1
-8y + 4z + 16 + y -2z = 1
-8y + y = 2z - 4z + 1 - 16
-7y = -2z - 15
y = -(2z + 15)/-7
y = (2z + 15)/7 (equation 5)
2x + 2y - z = 10 (equation 3)
2(2y - z - 4) + 2y - z = 10
4y - 2z - 8 + 2y - z = 10
4y + 2y = 2z + z + 10 + 8
6y = 3z + 18
y = (1/2)z + 3 (equation 6)
Substitute the value of y from equation 5 to equation 6 and solve for z.
y = (1/2)z + 3 (equation 6)
(2z + 15)/7 = (1/2)z + 3
2z + 15 = 7[(1/2)z + 3]
2z + 15 = (7/2)z + 21
2z - (7/2)z = 21 - 15
(-3/2)z = 6
z = -4
Substitute the value of z in either equation 5 or 6.
y = (1/2)z + 3 (equation 6)
y = (1/2)(-4) + 3
y = -2 + 3
y = 1
Finally, substitute the value of y and z to equation 4 and solve for x.
x = 2y - z - 4 (equation 4)
x = 2(1) - (-4) - 4
x = 2 + 4 -4
x = 2
Hence, the solution of the given system of equations is (x , y , z) = (2 , 1 , -4).

Write an equation of each line.slope = 5/6 ; through (22,12)
The equation of the line in point-slope form, with slope equal to 5/6 and passing through the point located at (22 , 12), is (y - 12) = 5/6(x - 22).
The equation of a line can be expressed in three different forms: standard form, slope-intercept form, and point-slope form.
The standard form of an equation of a line is expressed as ax + by = c, where a and b, if all possible must be integers, are the coefficients of variable x and y, respectively, and c is a constant. Meanwhile, slope-intercept form is given by the formula y = mx + b, where m is the slope of the line and b is the y- intercept. On the other hand, given the slope m and a point on the line (x , y), we can express the equation in point-slope form, (y - y1) = m(x - x1).
Using the point slope form, plug in the values to set up the equation.
(y - y1) = m(x - x1)
where m = 5/6 and (x1 , y1) = (22 , 12)
(y - 12) = 5/6(x - 22)
In slope-intercept form, the equation of the line is:
(y - 12) = 5/6(x - 22)
y - 12 = 5/6 x - 110/6
y = 5/6 x - 19/3
In standard form, the equation of the line is:
y = 5/6 x - 19/3
5/6 x - y = 19/3

The ratio of the surface area of the large sphere to the surface area of the small sphere of radius 20π meters and 6π meters, respectively, is B. 100/9.
Surface area refers to the total area covering the outside of a three dimensional shape. The surface area of a sphere is given by the formula:
A = 4πr^2
Solving for the surface area of each sphere:
1. larger sphere, r = 20π meters
A = 4πr^2
A = 4π(20π meters)^2
A = 4π(400π^2 square meters)
A = 1600π^3 square meters
2. smaller sphere, r = 6π meters
A = 4πr^2
A = 4π(6π meters)^2
A = 4π(36π^2 square meters)
A = 144π^3 square meters
