We will see that there are 19,656,000 different passwords that can be made with the given characters.
How many passwords are possible?We need to find the number of possible options for each character of the password.
The first character is a letter, so we have 26 options.
The second character is another letter, so we have 25 options (because we can't repeat).
Then we have 5 digits, for each digit we have 10 options (removing one for each subsequent one)
First digit: 10 options.Second digit: 9 options.Third digit: 8 options.Fourth digit: 7 options.Fifth digit: 6 optionsThe total number of passwords is given by the product between the numbers of options.

What is the slope of the line perpendicular to the line represented by the equation 2x+2y=-12
The slope of the line perpendicular to the line given by equation 2x+2y=-12 is found as 1.
What is the definition of line slope?The slope of a line measures its steepness as well as direction.The slope of a line is defined as the change throughout y coordinate in relation to the transitions in x coordinate.The net change in y coordinates is Δy, while the net change in x coordinates is Δx.So m represents the change in y coordinate in relation to a shift in x coordinate.The slope can be calculated using the following formula:
m = Δy/Δx
Where, m is the slope.
The equation of the line is; 2x+2y=-12
Write the equation in slope-intercept form.
2x + 2y = -12
Divide by 2.
x + y = -6
y = -x - 6
Slope m₁ = -1 and y-intercept = -6.
As, both line are perpendicular.
Thus,
m₁ x m₂ = -1
m₂ = -1/m₁
Put the value.
m₂ = -1/(-1)
m₂ = 1
The slope of the perpendicular line is found as 1.

Three times the first of two numbers decreased by the second number equals 9. Twice the first number increased by the second number equals 11. Find the two numbers
As per the given condition for the system of equation, the two numbers are equal to 4 and 3.
As given in the question,
To begin with the solution, let the two unknown numbers be x and y. Now, translating the two mathematical statements into system of equations,
When three times the first of two numbers decreased by the second number equals 9.
3 x - y = 9 ____(1)
Twice the first number increased by the second number equals 11,
2 x + y = 11 ____(2)
By solving resultant system of equations we get,
3 x - y = 9
2 x + y = 11
5x = 20 (by adding the two equations)
=> x = 4
Substituting the value of x in second equation,
y = 11 - 2x
= 11 - 2(4)
= 11 - 8 = 3
Therefore, as per given condition for the system of equation, the two numbers are equal to 4 and 3.

A linear equation is an algebraic equation of the form y = mx + b. The cost of renting the truck if the truck is driven 107 miles exists $32.63.
What is meant by linear equation?A linear equation is an algebraic equation of the form y = mx + b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. The variables in the preceding equation are y and x, and it is occasionally referred to as a "linear equation of two variables."
An equation is said to be linear if the maximum power of the variable is consistently 1. Another name for it is a one-degree equation. A linear equation with one variable has the conventional form Ax + B = 0. In this case, the variables x and A are variables, while B is a constant.
Number of miles travel exists represented by "x"
cost per mile is represented by "c"

Carlos has a smart phone data plan that costs $20 per month that includes 7 GB of data, but will charge an extra $15 per GB over the included amount. How much would Carlos have to pay in a month where he used 4 GB over the limit? How much would Carlos have to pay in a month where he used went over by x GB?
Answer:
Carlos will end up paying 80£ in that month, the standard data plan cost 20£ plus 60£ the price of the extra 4 GB of data used.
Carlos has to pay total $80 in a month if he uses 4 GB data over the limit and if he uses x GB data over the limit then have to pay $20+15x.
What is ratio?Ratio basically compares quantities, that means it show value of one quantity with respect to other quantity.
If a and b are two values, their ratio will be a:b,
Given that,
Cost of 7 GB data plan = $20,
Cost for extra data = $15 per GB.
Since, Carlos use extra 4 GB data in a month,
Cost of 1 GB extra data = $15
Cost of 4 GB extra data = $60
Total cost = cost of 7 GB data plan + Cost of 4 GB extra data
= $20 + $60
= $80
Total $80 Carlos have to pay, where he used 4 GB over the limit.
If Carlos uses x GB extra data,
Then cost of x GB extra data = $15x
Total cost = cost of 7 GB data plan + Cost of x GB extra data
= 20 + 15x
Total $20+15x Carlos have to pay, where he used x GB over the limit.

The point (-13, 24) is on the graph of y = f(x). Find the corresponding point on the graph of y= g(x), where g(x) = 1/4f(x)
Answer:
(−12,2)
Step-by-step explanation:
1:
Dividing the function by 2 divides all the y-values by 2 as well. So to get the new point, we will take the y-value
(4) and divide it by 2 to get 2
.
Therefore, the new point is
(−12,2)
2:
Subtracting 2 from the input of the function makes all of the x-values increase by 2 (in order to compensate for the subtraction). We will need to add 2 to the x-value
(−12) to get −10
.
Therefore, the new point is
(-10,4)
3:
Making the input of the function negative will multiply every x-value by
−
1
. To get the new point, we will take the x-value
(−12) and multiply it by −1 to get 12.
Therefore, the new point is
(12,4)
4:
Multiplying the input of the function by 4 makes all of the x-values be divided by 4 (in order to compensate for the multiplication). We will need to divide the x-value
(−12) by 4 to get −3
.
Therefore, the new point is
(−3,4)
5:
Multiplying the whole function by
4
increases all y-values by a factor of
4
, so the new y-value will be
4
times the original value
(4), or 16.
Therefore, the new point is
(−12,16)
6:
Multiplying the whole function by
−1
also multiplies every y-value by
−1
, so the new y-value will be
−1
times the original value
(4), or −4.
Therefore, the new point is
(−12,−4)

Answer:
see the attachments for the sketch and the graphA = x(120 -2x)x = 30 maximizes the areadimensions: 30 m by 60 mdomain of x: [0, 60]Step-by-step explanation:
You want an expression for area, maximum area, and dimensions of a rectangular pen fenced on three sides with a total of 120 m of fencing.
a) SketchThe first attachment shows a sketch of the pen with x defined as the dimension the pen extends from the barn wall. The total length of fence is 120 m, so the side parallel to the barn will be (120 -2x) m in length.
b) AreaThe area is the product of the length and width of the rectangle:
A = (x)(120 -2x)
c) GraphThe second attachment shows a graph of the area as a function of x.
d) Greatest areaThe value of x that gives the greatest area is the x-coordinate of the vertex of the parabola. It is halfway between the zeros at x=0 and x=60. The maximum area will be had when x=30.
e) DimensionsThe dimensions of the pen are ...
x = 30
120 -2x = 120 -2(30) = 60
The pen is 30 m by 60 m, with the 60 m dimension parallel to the barn wall.
f) DomainThe area function only makes sense for values of x between 0 and 60 meters.
The domain of x is 0 ≤ x ≤ 60.
