Deepak is choosing a password for his phone using letters from the alphabet, A-Z. The password must be four letters long, and he can repeat letters. How many different passwords can he create?
Answers
Answer: 26 × 4
Step-by-step explanation: There are 26 letters in the alphabet lettered A through Z.
Deepak is given the choice of picking a four letter password of his liking, using any four letters. Since the letters he uses can be repeated, it is 26 * 4 possibilities, since there are 26 different possibilities of letters from the alphabet he could choose, for 4 times. Also, since letters can be repeated, 26 stays the same. If letters could not be repeated, it would be 26 * 25 * 24 * 23.
Answer:
B. 26⁴
Step-by-step explanation:
If the password is 4 letters long and he can repeat letters then:
1st letter: any one of the 26 letters from the alphabet2nd letter: any one of the 26 letters from the alphabet3rd letter: any one of the 26 letters from the alphabet4th letter: any one of the 26 letters from the alphabetTherefore, to find the total number of passwords he can create, simply multiply the number of permutations for each letter of his password:
⇒ 26 × 26 × 26 × 26 = 26⁴

A computer manufacturer built a new facility for assembling computers. There were construction and new equipment costs. The company paid for these costs and made combined profits of $80 million after 4 years, as shown in the graph:
There is a graph of a line with Years on the x axis and Profits in millions on the y axis that passes through 1, negative 100 and 4, 80.
Which equation most closely represents the line depicted in the graph?
f(x) = 60x − 160
f(x) = −60x + 160
f(x) = −80x + 4
f(x) = 80x − 4
Answers
The equation that most closely represents the line depicted in the graph is; f(x) = 60x − 160
How to find the equation of a Graph?We're given a point of the graph (4, 80).
From the complete question seen online, we see that the profits increased $60 million per year. Thus, slope = 60.
Let us write the equation and find x and y intercepts.
y = 60x + b
Thus;
80 = 60*4 + b
80 = 240 + b
b = -160
Thus, the equation that most closely represents the line depicted in the graph is; f(x) = 60x − 160

Transformation is a process in which the dimensions or orientation of a given plane shape is changed. The required answers are:
Graph 1: Reflection
Graph 2: Translation
Graph 3: Rotation
Graph 4: Rotation
Graph 5: Translation
Graph 6: Reflection
Transformation is the process in which the dimensions or orientation is a given shape is changed. The major types are reflection, dilation, translation, and rotation.
Reflection is a transformation method in which a given shape is flipped over a given reference point or line. Dilation is a transformation method that involves either increasing or decreasing the length of sides of a given shape.Translation is a transformation method that requires the movement of all points of a shape with respect to a given reference point or line.Rotation is a transformation method that involves the rotation of a given shape at a certain degree clockwise or counterclockwise.Thus the transformation process that was applied to the original figure for each graph is:
Graph 1: Reflection along the y-axis
Graph 2: Translation at 4 units in the -x direction
Graph 3: [tex]90^{o}[/tex] clockwise Rotation
Graph 4: [tex]180^{o}[/tex] clockwise Rotation

What is the solution to this equation?
6 * (x - 5) = 4x + 20
6x - 30 = 4x + 20
2x = 20 + 30
2x = 50
x = 50 : 2
x = 25
-------------------
check
6 * ( 25 - 5) = 4 * 25 + 20
6 * 20 = 100 + 20
120 = 120
the answer is good
Answer:
x=25Step-by-step explanation:
6(x-5) 4x+20
Distribute.
6x-30 = 4x+20
Subtract 4x from each side.
6x-4x-30 = 4x-4x+20
Simplify.
2x-30=20
Add 30 to both sides.
2x-30+30 = 20+30
Simplify.
2x = 50
Divide both sides by 2
2x/2 = 50/2
Simplify
x = 25
So, x = 25!

A livestock pen is built in the shape of a rectangle that is 3 times as long as it is wide. The perimeter is 56 feet. If the material used to build the pen is $1.50 per foot for the longer sides and $2.75 per foot for the shorter sides (the shorter sides have gates, which increase the cost per foot), find the cost to build the pen.
Answers
The cost of the shorter and longer side of the rectangular pen is $19.25 and $31.50 respectively.
Perimeter of rectangleWidth = xLength = 3xPerimeter = 56 feetPerimeter = 2(length + width)

Function g can be thought of as a translated (shifted) version of f(x)=x^2
Answers
Answer:
g(x)=x^2 -6x +5
Step-by-step explanation:
Answer:
g(x) = (x - 3)² - 4
Step-by-step explanation:
When values are directly added to the "x" variable (usually inside of parentheses), the function shifts to the left that many units.
When values are directly subtracted from the "x" variable, the function shifts to the right that many units.
When values are added to an overall function, the function shifts upwards that many units.
When a value is subtracted from an overall function, the function shifts downwards that many units.
We can determine how the function has been translated by looking at the changed position of the vertex (the lowest point of the line).
As you can see, the new vertex now lies on x = 3 rather than x = 0.This means that there should be a -3 directly next to the "x" variable in the new function.
The new vertex also now lies on y = -4 rather than y = 0. Therefore, there should be a -4 added to the overall equation.
These changes make the new function:
g(x) = (x - 3)² - 4
A movie theater has a seating capacity of 167. The theater charges $5.00 for children, $7.00 for students, and $12.00 for adults. There are half as many adults as there are children. If the total ticket sales was $ 1198, How many children, students, and adults attended?
Child attend:
Student attend:
Adult attend:
Answers
Answer:
Child attend: 58
Studen attend: 80
Adult attend: 29
Step-by-step explanation:
a + c + s = 167 Eq. 1
12a + 5c + 7s = 1198 Eq. 2
a = c/2 Eq. 3
a = adult attend
c = children attend
s = students attend
Replacing Eq, 3 in Eq. 2:
12(c/2) + 5c + 7s = 1198
6c + 5c + 7s = 1198
11c + 7s = 1198
7s = 1198 - 11c
s = (1198 - 11c) / 7 Eq, 4
Replacing Eq, 3 and Eq, 4 in Eq, 1
c/2 + c + (1198-11c) / 7 = 167
7c/14 + 14c/14 + 2(1198-11c)/14 = 2338/14
7c/14 + 14c/14 + 2396/14 - 22c/14 = 2338/14
7c + 14c + 2396 - 22c = 2338
7c + 14c - 22c = 2338 - 2396
-1c = -58
c = -58/-1
c = 58
from Eq. 3
a = c/2
a = 58/2
a = 29
from Eq. 4
s = (1198-11c)/7
s = (1198 - 11*58)/7
s = (1198 - 638) / 7
s = 560/7
s = 80
Check:
from Eq, 1
58 + 29 + 80 = 167
Soil sells for 8 1/4 cents per pound. How much would you save if you bought a 100- pound sack for $7.45?
Answers
Answer:
$0.80
Step-by-step explanation:
If the 100 pounds was bought separately (of course in real life you will probably not)
= 100 pounds x $0.0825/pound
= $8.25
As you can see it will cost more than if you buy a 100 pound sack.
Cost Difference = $8.25 - $7.45 = $0.80
That means you will save $0.80 from it.
There will be a profit of $0.8 if the soil is bought for $7.45 for 100- pound sack and sold for 8 1/4 cents per pound.
What is Multiplication?Multiplication in mathematics is the process of adding a number repeatedly up to the times of another number. If two numbers, namely a and b are multiplied, this is denoted by a × b. This means that 'a' is added repeatedly to itself up to b times or b is added repeatedly up to 'a' times.
Amount got for 1 pound soil after selling = 8 [tex]\frac{1}{4}[/tex] cents
= 33/4 cents
= 8.25 cents
= 8.25 / 100 dollars
= 0.0825 dollars
For 100 - pound sack, amount got after selling = 0.0825 × 100
= 8.25 dollars
Cost for 100 - pound sack = $7.45
Profit = $8.25 - $7.45
= $0.8
$0.8 will be saved if you bought a 100- pound sack for $7.45.

Force = (4x + 3y)
Distance = x = 5.00m
Work done = (4x + 3y) × x
Work done = 4x^ 2 + 3xy
Let's substitute the value of 'x'
