Answer:

\frac{1}{12}

Step-by-step explanation:

\frac{(\sqrt{4} + 3)2 - 9}{ (\sqrt{9} - 1)3 * 2}=\frac{(2+3)2-9}{(3-1)6}=\frac{10-9}{2*6}=\frac{1}{12}

To the nearest dollar, what does the analyst believe
ruslelena [56]

The analyst believes the value of the stock at the end of three weeks will be $134.

<h3>What are stocks?</h3>
  • Stock (also known as capital stock) in finance refers to the shares of ownership in a corporation or company.
  • A single share of stock represents fractional ownership of the corporation based on the total number of shares.
  • This typically entitles the shareholder (stockholder) to that fraction of the company's earnings, proceeds from asset liquidation (after discharge of all senior claims such as secured and unsecured debt),  or voting power, which are often divided in proportion to the amount of money invested by each stockholder.

To find the value of the stock:

  • Because the stock price drops by 28% every week, it will be:
  • 100 - 28 = 72% every week.
  • So, r = 0.72.
  • Then, the equation V = 360(r)∧t will be V = 360(0.72)∧t .
  • After 3 weeks, V = 360(0.72)³ = 134.47 = 134

Therefore, the analyst believes the value of the stock at the end of three weeks will be $134.

Carol is standing 8 feet from a lamppost. The angle of elevation from her eyes to the top of the lamppost is 20o, and the angle
kupik [55]

Answer:

Height of the lamppost = 5.602 ft + 2.912 ft = 8.514 ft

Step-by-step explanation:

The illustration form a triangle that can be demarcated into 2 right angle triangle. One triangle representing depression triangle and the other elevation triangle.

Depression triangle

The opposite side of the triangle formed is the length of the pole from the base to the horizontal line of sight. Therefore,

using tangential ratio

tan 35° = opposite/adjacent

tan 35° = a/8

cross multiply

a = 8 tan 35°

a = 8 × 0.70020753821

a = 5.60166030568

a = 5.602 ft

Elevation triangle

The opposite side of this right angle triangle represent the length from the horizontal line of sight to the top of the lamppost.

tan 20° = opposite/adjacent

tan 20° = b/8

cross multiply

b = 8 tan 20°

b = 8 × 0.36397023426

b = 2.91176187413

b = 2.912 ft

Height of the lamppost = 5.602 ft + 2.912 ft = 8.514 ft
