A boat leaves the harbor entrance and travels 28 miles in the direction N 43° E. The captain then turns the boat 90° and travels
Serga [27]

Answer:

Step-by-step explanation:

A boat leaves the harbor entrance and travels 28 miles in the direction N 43° E.

Displacement in vector form

= 28 cos43 i + 28sin43j

= 20.47 i + 19.1 j

The captain then turns the boat 90° and travels another 15 miles in the direction S 47° E

Displacement

= 15 cos47 i - 15 sin47 j

= 10.22 i - 10.97 j

Total displacement

= 20.47 i + 19.1 j + 10.22 i - 10.97 j

= 30.69 i - 8.13 j

Magnitude of displacement

= 31.75 miles

Angle with east direction

TanФ = - 8.13 / 30.69

Ф = 15 degree  south of east.

Question set 2: Many species of terrestrial tree frogs that hibernate at or near the ground surface can survive prolonged exposu
joja [24]

Answer:

0.86

Step-by-step explanation:

The z-score we need to make the comparison is given by

\bf z=\frac{-2.05-(-2)}{\sigma/\sqrt{n}}

where

\bf \sigma= the standard deviation established in the study

n = the sample size

\bf z=\frac{-2.05-(-2)}{0.3/\sqrt{42}}=-1.0801

and for the Normal distribution N(0,1) we want to find  

<em>P(X > -1.0801) </em>

By using a spreadsheet or the table attached, we find that

P(X > -1.0801) = 0.86

(See picture attached)

Polygon R and polygon S are similar. The perimeter of polygon R is 136 cm, and the perimeter of polygon S is 64 cm. If one side
e-lub [12.9K]

<u>Answer </u>

Option A) 17cm

<u>Explanation </u>

Polygon R and polygon S are similar. This means the polygon R and S have equal number of sides.

Step 1 : Find the number of sides of polygon S

The perimeter of polygon S is 64 cm. If one side of polygon S is 8 cm

Therefore, Number of sides of polygon S = 64/8 = 8 sides

and number of sides of polygon R = 8 side

Step 2 : Find the number of sides of polygon R

The perimeter of polygon R is 136 cm,  

Number of sides of polygon R = 136/8 = 17 cm

Therefore side length of  polygon R = 17 cm
