What's the pattern for 2,4,7,9

Mathematics

Answer:

The pattern is this: I create a function p(x) such that

p(1)=1

p(2)=1

p(3)=3

p(4)=4

p(5)=6

p(6)=7

p(7)=9

Therefore, trivially evaluating at x=8 gives:

p(8)= 420+(cos(15))^3 -(arccsc(0.304))^(e^56) + zeta(2)

Ok, I know this isn’t what you were looking for. Be careful, you must specify what type of pattern is needed, because the above satisfies the given constraints.

Answer:

$\displaystyle n^3-\frac{1}{n^{2}}$

Step-by-step explanation:

Exponents Properties

We need to recall the following properties of exponents:

$(a^x)^y=(a^y)^x=a^{xy}$

$\displaystyle a^{-x}=\frac{1}{a^x}$

We are given the expression:

$2^m=n$

We need to express the following expression in terms of n.

$8^m-4^{-m}$

It's necessary to modify the expression to use the given equivalence.

Recall $8=2^3 \text{ and }4 = 2^2$ . Thus:

$(2^3)^m-(2^2)^{-m}$

Applying the property:

$(2^m)^3-(2^m)^{-2}$

Substituting the given expression:

$n^3-n^{-2}$

Or, equivalently:

$\mathbf{\displaystyle 8^m-4^{-m}= n^3-\frac{1}{n^{2}}}$

Suppose that x and y vary inversely and that y = 5 when x = 1. What is y when x = 15?

LiRa [457]

Answer:

Y=1/3

Step-by-step explanation:

X=k/y

So let's make k the subject of formula

k=xy

x=1,y=5

So let's substitute

k=1×5

k=5

So we are to determine the value for y when x is 15

So let's solve

Y=k/x

Y=5/15

Y=1/3

Y=0.333333~0.3

Shows that usually cost $124.95 are on sale for $87.46. What percent off are they?

Ad libitum [116K]

Answer: They are 30% off

Step-by-step explanation:

$124.95 - 30% (37.485)

124.95-37.485= 87.465

Find the measure of angle A. 4x 135° 5x A

Mkey [24]

<h2>Using this equation:</h2>

 $4 \times + 5 \times + 135 = 180$ 

<h2>We can solve for X:</h2>

 $9 \times + 135 = 180 \\ 9 \times = 45 \\ \times = 45$ 

<h2>Multiply this value of x to 4 and 5 to get the other two angels.</h2>

What is f(-2) for f(x) = x^2+3x=5

leva [86]

f(x) = x^2+3x+5

f(-2) = (-2)^2 +3(-2)+5

f(-2) = 4-6+5

f(-2) = -2+5

f(-2) = 3
