Use an induction proof to prove this statement:
For n≥1, 4^n+5 is divisible by 3.
Answer:
See below
Step-by-step explanation:
We shall prove that for all [tex]n\in\mathbb{N},3|(4^n+5)[/tex]. This tells us that 3 divides 4^n+5 with a remainder of zero.
If we let [tex]n=1[/tex], then we have [tex]4^{1}+5=9[/tex], and evidently, [tex]9|3[/tex].
Assume that [tex]4^n+5[/tex] is divisible by [tex]3[/tex] for [tex]n=k, k\in\mathbb{N}[/tex]. Then, by this assumption, [tex]3|(4^n+5)\Rightarrow4^k+5=3m,\: m\in\mathbb{Z}[/tex].
Now, let [tex]n=k+1[/tex]. Then:
[tex]4^{k+1}+5=4^k\cdot4+5\\=4^k(3+1)+5\\=3\cdot4^k+4^k+5\\=3\cdot4^k+3m\\=3(4^k+m)[/tex]
Since [tex]3|(4^k+m)[/tex], we may conclude, by the axiom of induction, that the property holds for all [tex]n\in\mathbb{N}[/tex].
Determine whether the relation is a function.

O Not a function

someone please help!!!!
Answer:
NOT a function!
Step-by-step explanation:
A function is a relation where each input has only one and ONLY one output. For example, for the number 2 in a relation, that number 2 can only have one other y value it is paired with, it can not have more than one.
For example, in this problem the number 2 is stated twice. One set has (2, -8) and (2, 8), so that means this input has more than one output. Therefore, this relation is NOT a function.

If f(x) = 7x+ 8, find f'(x).
Answer:
f'(x) = 7
Step-by-step explanation:
This is a basic derivative problem. The first derivative of f(x) would multiply the 7 by the power of x (which is one) and get rid of the 8. So, all you have left is 7 times 1 and your answer would be 7.
Answer:
x=-8/7 or -1.1428
Step-by-step explanation:
The roots (zeros) are the x
values where the graph intersects the x-axis. To find the roots (zeros), replace f(x) with 0 and solve for x

the price of a garment is reduced by 15% in sale to $30. find its original price
Answer:
x =35.29
Step-by-step explanation:
If it is reduced by 15%, you are paying 100-15 = 85%
The original price is x
x* 85% = 30
x *.85 = 30
Divide each side by x
x = 30/.85
x =35.29
Answer:
$25.50
Step-by-step explanation:
if 85% of $30 is $4.50, we subtract $4.50 from $30 and get $25.50
Emily spent 40% of her check on rent, 12% on groceries, and 16% on untilities. how much did she have left from her $260 check?
Answer:
83.20
Step-by-step explanation:
If 0.40 + 0.12 + 0.16 = 0.68
then it would be 260x(1-0.68)=83.2
83.2 complete would be 83.20.

what is 2x =6.5
And how
Answer:
Step-by-step explanation:
2x =6.5
To find the value of x, divide both sides by 2 so you will have 1x.
x = 3.25
Answer:
2x = 6.5
x = 6.5/2
(move the 2 and flip its sign. It was multiplication before the equal sign, so now it will be division.)
x = 3.25

When multiplying a positive number with a negative number, the product will always be negative. First, let's solve the problem disregarding the negative sign.
[tex]\frac{1}{4} * 12[/tex] [tex]\frac{12}{4}[/tex] [tex]3[/tex]Now that we know the product of 1/4 x 12 is 3, we can assume that the product of 1/4 x -12 is -3.

if 12 percent of a number is 24 what is the number
Answer:
It's 200
Step-by-step explanation:
Think of it like this:
24/12 = 2
so, 2 x 100 (bc it's 12 percent)
which equals 200.
I hope this helps! If it doesn't, feel free to tell me in the comments below for further explanation!
If 12 percent of a number is 24. The number is 200.
Let's consider number is x,
Given statement is if 12 percent of a number is 24 what is the number
So, x * 12% = 24
Simplify this,
x * 12/100 = 24
x = (24 * 100) / 12
x = 2 * 100
x = 200.
To checking this
12 percent of a number is 24
200 * 12% = 24
200 * 12/100 = 24
24 = 24.
Therefore, the number is 200.

Write an equation of the line below.
Answer:
y=4x-2
Step-by-step explanation:
We'll figure this out using our equation y=mx+b! m = slope and b = y-intercept. You start on the y line at -2 so we already know our y-intercept will be -2 so we have half the equation done, use rise (y) over run (x) to figure out the slope from (0,-2) to (1,2) as they're our two closest points, though you can work from wherever you choose. Our difference in y is 4 and our difference in x is 1, so 4 over 1 (4/1) = 4 our slope. :-) hope this helped and that I didn't oversimplify lol
