Given:
f(x) = x^4 - x

g(x) = x^4 (even)
h(x) = -x (odd)

f(x) as a sum of an even function and an odd function

f(x) = g(x) + h(x)

s(x) = 1 / (x^4 - x)

s(x) as a sum of an even function and an odd function

s(x) = 1 / [g(x) + h(x)]

4(2x - 3) = 6x + 2

Expand it:

8x - 12 = 6x + 2

+ 12 to both sides

8x = 6x + 14

- 6x from both sides

2x = 14

Divide both sides by 2:

x = 7

Suppose a company produces report indicates that the surveyed distance between two points is 1200 feet with a margin of error of

Otrada [13]

<h2>Hello!</h2>

The answers are:

$MaximumDistance=1200.1ft\\MinimumDistance=1199.9ft$

Since we are given the margin of error and it's equal to ±0.1 feet, and we know the surveyed distance, we can calculate the maximum and minimum distance. We must remember that margin of errors usually involves and maximum and minimum margin of a measure, and it means that the real measure will not be greater or less than the values located at the margins.

We know that the surveyed distance is 1200 feet with a margin of error of ±0.1 feet, so, we can calculate the maximum and minimum distances that the reader could assume in the following way:

$MaximumDistance=ActualDistance+0.1feet\\\\MaximumDistance=1200feet+0.1feet=1200.1feet$

$MinimumDistance=ActualDistance-0.1feet\\\\MaximumDistance=1200feet-0.1feet=1199.9feet$

Have a nice day!

The difference between a number b and 7.4 is -6.8

Lera25 [3.4K]

Hello from MrBillDoesMath!

Answer:

b = 0.6

Discussion:

The question can be written as

b - 7.4 = -6.8 => (now add 7.4 to each side)

b - 7.4 + 7.4 = -6.8 + 7.4 => ( note: -7.4 + 7.4 = 0)

b = 0.6

Thank you,

State if the two triangles are congruent. If they are, prove by using a two column proof!!!

Goshia [24]

Answer:

Step-by-step explanation:

There are four axioms to prove the triangles are contruent.They are

SSS(side side side axiom)

SAS(side angle side axiom)

AAS(angle angle side axiom)

ASA(angle side angle axiom)

RHS (right angle hypotenuse side axiom)

here two triangles are congruent by RHS axiom
