Rehan proved by mathematical Induction that for all the positive Integers, n^3+ 2n is divisible by 3. Can you find an integer counterexample to show that this statement is not true? Explain.
Reproduce the proof. When n = 1, we have
n³ + 2n = 1³ + 2 = 3
which is clearly divisible by 3.
Assume n³ + 2n is divisible by 3. Then for the next natural number n + 1, we have
(n + 1)³ + 2 (n + 1) = n³ + 3n² + 3n + 1 + 2n + 2
= n³ + 2n + 3 (n² + n + 1)
The first two terms n³ + 2n are divisible by 3 according to our assumption, and 3 (n² + n + 1) is clearly a multiple of, and therefore divisible by, 3 as well.
So the claim that 3 divides n³ + 2n is true for all natural numbers n.
Find next 2 terms. -6, -12, -24, ?, ?
Answer:
-48, -96
Step-by-step explanation:
Pattern: The terms double as they go on.
Answer:
Tn=ar^(n-1)
a=first term
r=common ratio
Tn= term n
a= -6
r= -12÷-6 = 2
T4= -6(2)^(4-1) =48
T5= -6(2)^(5-1) =96
The table below represents a linear function. Identify the rate of change of the function.
(0,4) (4,-3) (8,-10) (12,-17)
Step-by-step explanation:
the rate of change is the slope of the line y/x. it is always the factor of x in the equation.
it indicates how many units y changes, when x changes a certain amount of units when going from one point to another.
we only need to look at 2 points.
to go from (0, 4) to (4, -3)
x changes by +4 (from 0 to 4),
y changes by -7 (from 4 to -3).
so the rate of change is -7/3
Enter the greatest common factor of 6 and 4

Convert the following
275mm = ______ cm
1,000L = _____kL
Answer:
275mm = 27.5cm
1,000L = 1 kL
Hope this helps :)
275mm= 27.5cm and 1000L= 1KL
Step-by-step explanation:
For 257mm to get to 27.5cm, you have to divide the length value by 10 and so it becomes 27.5. Also for 1000L to become to 1KL you have to divide the volume value by 1000.

(Please Help) (50 Points) Write the equation for the transformations of the graph of y = x^2
Use the form: y = a (x-h)^2 +k

A is the scale or vertical stretch
H is what makes it move right or left.
K is what makes it move up or down.
a = 1
h = -2
k = -7

Need help with number 4 only
Answer: The filled out chart is shown below.
===========================================================
Explanation:
For each row, we divide the number of locations over the population count. Treat the population values in millions. Something like 35.2 million means 35,200,000 which is the same as writing 35.2*10^6 when using scientific notation. I prefer to stick to scientific notation.
In the first row, they computed 1460/(35.2*10^6) = 0.0000415 = 4.15*10^(-5); the last entry of 4.15 for this row represents having 4.15 stores for 100,000 people. In other words, we chop off the 10^(-5) portion in 4.15*10^(-5). This is because the 10^(-5) portion represents "1 out of 100,000".
The other remaining rows are handled the same way. I'll show the steps for the second row
per capita as a decimal = 6530/(325.7*10^6) = 0.00002per capita as sci notation = 2 * 10^(-5)Starbucks per 100,000 = 2Like the previous row, each value is approximate.
Check out the table below. The stuff in gray represents the new entries that were previously blank.

What is a number system?The number system is a way to represent or express numbers.
A decimal number is a very common number that we use frequently.
Any of the multiple sets of symbols and the guidelines for utilizing them to represent numbers are included in the Number System.
As per the given,
Product of 0.4 and n is 8.
0.4n = 8
n = 8/0.4
n = 80/4 = 20
Hence "The answer will be n = 20 because the equation says that 0.4n = 8".

Write an equation for the graph shown in the form y=ax+b.
Answer:
y=0.2x+1
Step-by-step explanation:
2=5a+b
1.2=1a+b
0=-5a+b
we get that a=0.2, b=1
The required equation will be y = -0.5x + 27.5 passes through the points (-5, 0) and (5, 2).
What is the Linear equation?A linear equation is defined as an equation in which the highest power of the variable is always one.
According to the given graph,
We can see two points are (-5, 0) and (5, 2)
The linear equation will be: y - y₁ = (y₂ - y₁)/(x₂ -x₁ )[x -x₁]
Here
x₁ = -5, y₁ = 0
x₂ = 5, y₂ = 2
⇒ y - y₁ = (y₂ - y₁)/(x₂ -x₁ )[x -x₂]
Substitute values in the equation, we get
⇒ y - 0 = (2 - 0)/(8-4)(x-(-5))
⇒ y - 30 = (2)/(-4)(x + 5)
⇒ y - 30 = -1/2(x + 5)
⇒ y = (-1/2)x - 5/2 + 30
⇒ y = -0.5x + 27.5
Thus, the required equation will be y = -0.5x + 27.5 passes through the points (-5, 0) and (5, 2).

Answer:
x = 11
Step-by-step explanation:
∠ EAB = ∠ AED = 4x ( alternate angles )
∠ AEB and ∠ GEB are adjacent angles on a straight line and sum to 180° , so
∠ AEB + 125° = 180° ( subtract 125° from both sides )
∠ AEB = 55°
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ EBC is an exterior angle of the triangle , then
∠ EBC = ∠ AEB + ∠EAB , that is
9x = 55 + 4x ( subtract 4x from both sides )
5x = 55 ( divide both sides by 5 )
x = 11

The probability that a new vacuum cleaner has a fault is 0.013
What is the probability that a new vacuum cleaner does not have a fault
Based on the probability that the new vacuum cleaner has a fault, the probability that it does not have a fault is 0.987.
This refers to a mutually exclusive scenario in that the vacuum cleaner can either have a fault or will not have a fault.
When that happens, the probability of one occurring can be found by deducting the probability of the other occurring from 1.
The probability of the cleaner not having a fault is therefore:
= 1 - 0.013
= 0.987
In conclusion, the probability that the cleaner does not have a fault is 0.987.
