GCF - Greatest Common Factor
It is simply the largest of the common factors.
We have:
12x³- 18x² + 6x
We find GCF of 12, 18 and 6:
GCF(12, 18, 6) = 6
12 = 2 · 6
18 = 3 · 6
6 = 1 · 6
and GCF of x³, x² and x:
GCF(x³, x², x) = x
x³ = x² · x
x² = x · x
x = 1 · x
Therefore:
12x³- 18x² + 6x = 6x(2x² - 6x + 1)Graph the inequality y+4<-2(x-4) on the set of axes below

Use an appropriate infinite series method about x = 0 to find two solutions of the given differential equation. (Enter the first four nonzero terms for each linearly independent solution, if there are fewer than four nonzero terms then enter all terms. In each case, the first term has been provided for you. )
3xy" y+y=0
Y₁ = 1 -
12 = x2/3
The two linearly independent solutions are y₁(x) = 1 - (x²/3) + (x⁴/81) - (x⁶/2187) + … and y₂(x) = x - (x³/9) + (x⁵/405) - (x⁷/21870) + ...
We can use the power series method to find the two solutions of the given differential equation:
Let y = ∑anxn be a power series solution. Then, we have:
y' = ∑nanxn-1
y'' = ∑nan(n-1)xn-2
Substituting these into the differential equation and equating coefficients of like powers of x, we get:
3x∑nan(n-1)xn-1 + ∑anxn = 0
Simplifying, we obtain:
∑[3nan(n-1) + an-1]xn = 0
Since x ≠ 0, the coefficients of like powers of x must be zero. This gives us the recurrence relation:
an = -an-1/(3n(n-1)), n ≥ 1
Using this recurrence relation and the initial condition y(0) = 1, we can find the power series solution:
y₁(x) = 1 - (x²/3) + (x⁴/81) - (x⁶/2187) + ...
To find a second linearly independent solution, we can use the method of reduction of order. Let y₂(x) = v(x)y₁(x). Then, we have:
y₂' = v'y₁ + vy₁'
y₂'' = v''y₁ + 2v'y₁' + vy₁''
Substituting these into the differential equation and simplifying, we get:
v''y1x + (2v'y1' + vy1'')x + 3vy1 = 0
Since y₁(x) is a solution, we have:
y₁'' + (1/3x)y₁ = 0
Multiplying by y1 and integrating, we obtain:
(y₁')² + y₁²/3 = C
where C is a constant of integration. Using the initial condition y₂(0) = 0, we can find the second solution:
y₂(x) = x - (x³/9) + (x⁵/405) - (x⁷/21870) + ...

The exponential functions y=1.2ˣ shows exponential growth and y=0.71ˣ shows exponential decay.
What exactly are exponential functions?
Exponential functions are functions that involve a variable exponent. They are of the form f(x) = aˣ, where "a" is a positive constant base and "x" is the variable exponent.
Exponential functions exhibit rapid growth or decay, depending on the value of "a" and the sign of "x". For example, if "a" is greater than 1, the function grows rapidly as "x" increases, while if "a" is between 0 and 1, the function decays rapidly as "x" increases.
Now,
As stated above that for exponential function y=aˣ
when a>1 it shows exponential growth
and when a<1 it shows decay.
hence,
The exponential functions y=1.2ˣ shows exponential growth and y=0.71ˣ shows exponential decay.

Question 3 of 12 , Step 1 of 1 Find three consecutive integers whose sum is 360.
The three consecutive integers whose sum is 360 are 119, 120, and 121.
To find three consecutive integers whose sum is 360, we can use algebra to set up an equation and solve for the first integer. Let x be the first integer, then the next two consecutive integers will be x+1 and x+2. The sum of these three integers is 360, so we can write the equation:
x + (x+1) + (x+2) = 360
Simplifying the equation gives us:
3x + 3 = 360
Subtracting 3 from both sides gives us:
3x = 357
Dividing both sides by 3 gives us:
x = 119
So the first integer is 119. The next two consecutive integers are 120 and 121. Therefore, the three consecutive integers whose sum is 360 are 119, 120, and 121.

The surface area of a rectangular prism is 250 cm 2. If its height is 10 centimeters, and its width is 5 centimeters, what is its volume?
The volume of the rectangular prism whose surface area is 250 cm square is 250cubic centimeters.
The surface area of a rectanular prism is calculates by the formula
= 2( length*width + length*height + width*height ) square units
Let the length of the given prism be l centimeters.
Given, width is 5 centimeters and height is 10 centimeters of the rectangular prism.
The surface area of the rectangular prism is 250 cm square.
Thus by the above formula,
250 = 2 ( l*5 + l*10 +10*5)
⇒250 = 2 (15*l +50)
⇒ 250= 30*l + 100
⇒ 150 = 30*l
⇒l = 150/30 = 5 (centimeters)
Thus the volume of the given rectangular prism is calculated as
= ( length*width*height) cubic units
= (5*5*10) cubic centimeters

How to express a two logarithm into a single logarithm
Answer:
There are different methods to express a two logarithm into a single logarithm, depending on the specific form of the logarithms involved. Here are some examples:
Logarithms with the same base:
If you have two logarithms with the same base, you can use the following logarithmic identity:
log_a(x) + log_a(y) = log_a(xy)
Using this identity, you can express a sum or difference of logarithms with the same base as a single logarithm:
Example 1: log_2(3) + log_2(5) = log_2(3*5) = log_2(15)
Example 2: log_5(7) - log_5(2) = log_5(7/2)
Logarithms with different bases:
If you have two logarithms with different bases, you can use the following change of base formula to express them with a common base:
log_a(x) = log_b(x) / log_b(a)
Using this formula, you can rewrite a logarithm with a base a as a logarithm with a base b:
Example 1: log_2(7) = log_10(7) / log_10(2)
Example 2: log_5(2) = log_2(2) / log_2(5)
Once you have expressed both logarithms with the same base, you can apply the logarithmic identity from method 1 to simplify them into a single logarithm.

The correct answer is b. 81°F.
On a certain day, the temperature of the pool rose at a constant rate from 76°F at 10 A.M. to 91°F at 1 P.M. To find the temperature at 11 A.M., we need to find the rate of change in temperature and then use it to calculate the temperature at 11 A.M.
The rate of change in temperature can be found by dividing the difference in temperature by the difference in time:
Rate of change = (91°F - 76°F) / (1 P.M. - 10 A.M.) = 15°F / 3 hours = 5°F per hour
Now, we can use this rate of change to find the temperature at 11 A.M.:
Temperature at 11 A.M. = 76°F + (5°F per hour)(1 hour) = 81°F
Therefore, the correct answer is b. 81°F.

The cost of 5 pounds of bananas in 1939 would have been $2.709.
According to the US Bureau of Labor Statistics, the cost of 1 pound of bananas is $0.63/lb. In 1939, the cost of bananas was 14% lower. Therefore, to find the cost of bananas in 1939, we need to calculate 14% of $0.63/lb and then subtract it from $0.63/lb.
Calculate 14% of $0.63/lb
0.14 * $0.63/lb = $0.0882/lb
Subtract $0.0882/lb from $0.63/lb to get the cost of bananas in 1939
$0.63/lb - $0.0882/lb = $0.5418/lb
Multiply the cost of bananas in 1939 by the number of pounds Pam buys
$0.5418/lb * 5 lb = $2.709
Therefore, the cost of 5 pounds of bananas in 1939 would have been $2.709.

The sum of three consecutive integers is 18. Find the integers.

Answer:
5,6 and 7.
Step-by-step explanation:
I am not sure what the three step method is, but here is how I solved it.
Consecutive integers means integers in a row. For example, 5,6 7 are consecutive integers or -4,-3,-2 are consecutive integers.
Integers are all the whole numbers (0,1,2,3...) and their opposites (..., -3, -2, -1) 1/2 or -.23 are not integers.
Let x = the first number
Let x + 1 = the second number
Let x + 2 = the third number
x + (x + 1) + (x + 2) = 18 I do not need the parentheses, but I want you to see that the first number, plus the second number, plus the third number equals 18.
x + x + 1 + x + 2 = 18 Combine like terms
3x + 3 = 18 Subtract 3 from both sides of the equation
3x + 3 - 3 = 18 - 3
3x = 15 Divide both sides by 3
[tex]\frac{3x}{3}[/tex] = [tex]\frac{15}{3}[/tex]
x = 5
The first number is 5. The second number is 6 and the last number is 7.

x = 12 / (10y - 3) (10y - 3)
We can now re-use this number of x to represent the revenue from apple juice in the equation:
5yx = 3x + 12
5y(12 / (10y - 3)) = 3(12 / (10y - 3)) + 12
Therefore, Mr. Tan charges $1/7 for each cup of apple juice and (3/2)($1/7) Equals $3/14 for each cup of lemon juice.
He charges (5/7)($1/7) = $5/49 for 5y = 5(1/7) = 5/7 glasses of apple juice.
For a sum of (2/7)($3/14) = $3/49, he sells 2y = 2(1/7) = 2/7 cups of lemon juice.
For each 7 cups of juice sold, Mr. Tan makes a sum of $5/49 + $3/49 = $8/49.
Consider that he offers 2n cups of lemon juice and 5n glasses of apple juice. (2n)($3/14) + (5n)($1/7) = $6n/49 + $5n/49 = $11n/49
He makes $8/49 for every 7 cups of juice sold, so his overall profits will be some multiple of $8/49.
