Answer:

about 3.492

Step-by-step explanation:

The distance between points in polar coordinates can be found using the Law of Cosines. For vector magnitudes a and b, and angular difference C, the distance between them (c) can be found from ...

c^2 = a^2 +b^2 -2ab·cos(C)

= 7^2 +5^2 -2(7)(5)cos((217/180π -(-23/36)π)

= 74 -70cos(332°) ≈ 12.1937

c = √12.1937 ≈ 3.492

The distance between the given points is about 3.492 units.

Write the fraction 1/8 as a percent rounded to the nearest hundredth of a percent where necessary

Irina-Kira [14]

<span>To determine the answer to this you would divide the numerator by the denominator in an equation. The answer to that equation is 0.125. When converting a decimal to a percentage, you shift the decimal point over two places. Thus the percentage is 12.5% and it is unnecessary to round the result to the nearest hundredth of a percent. The answer is 12.5%.</span>
