Answer:

The distance = 2205 meters

Step-by-step explanation:

∵ The deep of the point = 1200 meters

∵ The point is 1850 meters west from the starting point

∵ The deep is ⊥ to the west

So to find the straight distance that the shark need to swim,

we will use Pythagoras theorem

∴ Distance = √(1200² + 1850²) = 2205 meters

lilavasa [31]

Answer:

\huge \boxed{ \boxed{ \tt 2xy(x + y)}}

Step-by-step explanation:

<h3>to understand this</h3><h3>you need to know about:</h3>
  • factoring
  • PEMDAS
<h3>tips and formulas:</h3>
  • (a+b)³=a³+3a²b+3ab²+b³
  • a³+b³=(a+b)(a²-ab+b²)
<h3>let's solve:</h3>
  1. \sf \: use \: 2nd \: formula \: to \: simplify :  \\  \sf(x + y {)}^{3}  - (x + y)( {x}^{2}  - xy +  {y}^{2} )
  2. \sf factor \: out \: (x + y) :  \\ (x + y )\{(x + y)^{2} - ( {x}^{2}  - xy +  {y}^{2}  \}
  3. \sf simplify :  \\ (x + y {)} \{ {x}^{2}  + 2xy +  {y}^{2}  -  {x}^{2}  + xy -  {y}^{2}  \}

Determine whether the sequence is geometric. If so, find the common ratio. 3.0, 6.0, 12.0, 24.0
Luba_88 [7]

Answer:

The sequence <u>is</u> geometric and the common ratio is 2

Step-by-step explanation:

A sequence is geometric if each term  (after the first one) is equal to the term before it times some constant number, called the 'common ratio'.

Examples:  1, 2, 4, 8, 16, ... has a common ratio of 2 because 2*2 = 4, and 4*2 = 8, and so on.

                 Also, -->  4, 2, 1, 1/2, 1/4/ 1/8, ... has a common ratio of 1/2 because

4 * 1/2 =  the next term 2, and 2 * 1/2 = the next trem 1/4, and son on.

In this case, 3 * 2 = 6

                    6 * 2 = 12

                    12 * 2 = 24

The sequence <u>is</u> geometric and the common ratio is 2
