Answer:

$\boxed{0.2}$

Step-by-step explanation:

Put -2 where x is in the function and do the arithmetic. Any number of calculators will compute this for you.

x ≈ 0.23781036584 ≈ 0.2

<em>Comment on the above result</em>

The number above came from the Google calculator (2nd attachment). Surprisingly, it is rounded incorrectly in the last displayed digit. To 20 significant digits, the value is ...

0.23781036584658190876

It appears the Google calculator didn't carry enough digits to get the answer correct in the last displayed decimal place.

-50 Points-<br> Find the area of the smaller sector.<br> Leave your answer in terms of pi.

quester [9]

The formula to find the area of a sector is:

A = $\frac{degree}{360} \pi r^{2}$

In this case:

Degree = 40

Radius = 8

^^^Plug these numbers into the formula given above

A = $\frac{40}{360} \pi 8^{2}$

Solve

A = $\frac{1}{9}$ π8²

A = $\frac{1}{9}$ π64

A = $\frac{64}{9}\pi$

A = 7.1111111π

When rounded:

7.1π is the area of the sector

Hope this helped!

Help me 3x+1/10=x-1/7 ok so I understand that I'm supposed to cross multiply so 1 x 10=10 7x3=21 so now do i do 21x-7? please He

koban [17]

Simplify both sides of the equation

3x+1/10 = x+ -1/7

Subtract x from both sides

3x+1/10 -x = x+ -1/7 -x

2x+1/10 = -1/7

Subtract 1/10 from both sides

2x+1/10 - 1/10 = -1/7 -1/10

2x= -17/70

Divide both sides by 2

2x/2 = -17/70/2

x= -17/140

decimal x will equal -0.121

Ask any questions you want and I hope that's help !

1/10 and 8/100 which is the correct sum

Ivanshal [37]

To add 1/10 and 8/100, they must have the same denominator.

To do this, multiply 1/10 by 10/10 (which equals one, so it doesn't change the value of the fraction).

Now you have 10/100 and 8/100. To add them, simply add the numerators and keep the denominators the same.

This results in 18/100, which can be simplified to 9/50.

How do the values compare? Order the values from least to greatest.

aleksley [76]

Im pretty sure it would be ordered: -2 1/2, -1/2, |1/2|, 1 1/2, |-2|, |-2 1/2|

This is because
-1/2 stays as -1/2
the absolute value of |-2| is 2
the absolute value of |1/2| is 1/2
the absolute value of |-2 1/2| is 2 1/2
-2 1/2 stays as -2 1/2
and 1 1/2 stays the same as well.
If you take all these numbers (-1/2, 2, 1/2, 2 1/2, -2 1/2, and 1 1/2) and order them from least to greatest, you would get:
-2 1/2, -1/2, 1/2, 1 1/2, 2, 2 1/2
which is -2 1/2, -1/2, |1/2|, 1 1/2, |-2|, |-2 1/2|

Im not exactly sure if it is all correct, but i hope this helps! :)
