The number is 2, 2^2=4,  2^-2=1/4

 First, you could solve this problem algebraically. You could write x^-2=1/4. Next, you may apply the Laws of Exponents, where there's the rule of a^-m=1/a^m. In this case, this shows that x^-2 is equal to 1/x^2. Plus, all you have to do now is solve algebraically, which you can do so by doing cross-products or taking the square root of 4 to find x, as x squared is equal to 4. Your final equation may look like 4=x^2, where you solve for x.

Order the side lengths , , , , and from least to greatest.
diamong [38]

Answer:

1. FH, 2. GH,  3.IH  4. GI,  5. FG

Step-by-step explanation:

According to a certain geometric theorem, the smallest angle is always opposite to the smallest side of a triangle. Likewise, the largest angle is always opposite to the largest side. Using this theorem we can properly order the angles and sides.

Additionally, the interior degrees of a triangle will always be 180, and the interior of this quadrilateral is 360 degrees. Using this we can determine the missing angles.

180 - 75 - 55 = 50 (first missing angle)

180 - 59 - 63 = 58 (second missing angle)

The smallest angle would be 50 degrees and the largest 75.

The second smallest is 55 degrees, the third smallest is 58 degrees, the fourth smallest is 59 degrees, and the fifth is 63 degrees.

Now, one thing that seems a bit confusing is the fact that GH is opposite to 2 different angles, so how do we know WHICH angle to use to find its length. From what I understand, we should be able to find the average of the two angles across from this side to see what its place would be in terms of length.

63 + 50 = 56.5

This would make side  GH larger than FH but less than HI

This is how I would solve the problem, and I think this is the correct order. Please let me know whether it turns out right.

One fifth of the sum of a number and -3 is twice the number
aleksley [76]

Answer:

x = \frac{-1}{3}

Step-by-step explanation:

Let the number be x.

\frac{1}{5} (x - 3) = 2x\\

x - 3 = 10x

9x = -3

x = \frac{-1}{3}\\

The tangent of an angle is 3.4. What is the measure of the angle to the nearest tenth? 52.9° 73.6° 99.8° 68.2°
ryzh [129]
Arctan(3.4) ≈ 73.6°. You can view the 3.4 as the slope of a line. Then it is clear the the 52.9 and 99.8 can't be right. If you have to do this without a calculator, it can be quite tricky...
