Which number produces an irrational number when multiplied by 1/2
Ludmilka [50]

Quick answer

Any irrational number. I can't think of any exception to this statement.

sqrt(5) is irrational.  1/2 * sqrt(5) is still irrational.

-sqrt(5) is irrational. -1/2 * sqrt(5) is still irrational

2 + sqrt(5) is irrational. Multiplying this by 1/2 is still irrational.

1/2(2 + sqrt(5) = 1 + 1/2 * sqrt(5) ) is irrational.

Conclusion

There are no exceptions to this.  All irrational numbers produce irrationals when multiplied by 1/2

Find the magnitude and direction of the vector. Round the length to the nearest tenth and the degree to the nearest unit. Diagra
astra-53 [7]
Refer to the diagram shown below.

The vector has a magnitude of a and a direction of θ degrees south of west. 

Use the Pythagorean Theorem to calculate a.
a² = (-530)² + (-200)² = 320900
a = √(320900) = 566.48 mi ≈ 566.5 mi

By definition,
tan θ = (-200)/(-530) = 0.3774
θ = tan⁻¹ 0.3774 = 20.68° ≈ 21°

Answer: about 566.5 mi; 21° south of west.

A student playing a board game believes that a standard six sided die is incorrectly weighted. The student thinks that the numbe
nexus9112 [7]

Answer:

Hₐ = P ( 1 ) > 1/6

Step-by-step explanation:

This is the answer because the question is asking you for the "alternative hypothesis" and that means that it's basically asking for the statement that agrees with what is being said.

Since we know that a student believes that he's seeing the number "1" too often, then we must find the equation that agrees with that statement, which is Hₐ = P ( 1 ) > 1/6.

P.S - I took the test and got a 100%.
