Answer:

  2√3

Step-by-step explanation:

You recognize this as a 30°-60°-90° triangle, so you know the hypotenuse (R) is twice the length of the shortest side (√3).

The magnitude of R is 2√3.

_____

In case you haven't memorized the ratios for a 30°-60°-90° triangle, you can use trigonometry and the fact that ...

  Sin = Opposite/Hypotenuse

  sin(30°) = √3/R

  R = √3/sin(30°) = √3/(1/2) = 2√3

Of course, doing this on your calculator will give a numerical answer, which you may not want.

kozerog [31]

Answer: There is 680% increase for the fund.

Step-by-step explanation:

Since we have given that

Number of shares they purchased = 1000

Cost of per share at the time of their marriage = $10

So, Amount of fund will be

1000\times 10=\$10000

Cost per share after 30 years = $78

So, Amount of fund will be

78\times 1000=\$78000

Percentage of increase for the fund will be given as

\frac{78000-10000}{10000}\times 100=680\%

Hence, there is 680% increase for the fund.

eduard

Answer:

x = 1/2 or x = -4

Step-by-step explanation:

Since the product equals zero, use the zero product rule.

(2x - 1)(x + 4) = 0

2x - 1 = 0 or x + 4 = 0

2x = 1   or   x = -4

x = 1/2 or x = -4
