kayden paddled a canoe to an island. the island is 8 miles from the shore. his trip to the island took two hours while paddling

Andrew [12]

Answer:

$2\text{ mph}$

Step-by-step explanation:

GIVEN: kayden paddled a canoe to an island. the island is $8$ miles from the shore. his trip to the island took two hours while paddling against the current. he paddles $6$ mph with no current.

TO FIND: what was the speed of the current.

SOLUTION:

distance of island from the shore $=8$ miles

total time taken by Kayden $=2$ hours

speed of Kayden in still water $=6\text{ mph}$

Let the speed of current be $x$

Speed of Kayden against current $=6-x\text{ mph}$

As,

$\text{Time}=\frac{\text{Distance}}{\text{speed}}$

$2=\frac{8}{6-x}$

$12-2x=8$

$x=2\text{ mph}$

Hence speed of current is $2\text{ mph}$

What is the rectangular form of z= 40(cos(7pi/6)+ i sin(7pi/6))

Anastaziya [24]

Answer:

C. $z = -20\sqrt{3}-i\,20$

Step-by-step explanation:

The rectangular form of a complex number is represented by the following formula:

$z = a+i\,b$ (1)

Where each coefficient can be determined as function of the polar components:

$a = r\cdot \cos \theta$ (2)

$b = r\cdot \sin \theta$ (3)

Where:

$r$ - Magnitude of the complex number, dimensionless.

$\theta$ - Direction of the complex number, measured in radians.

If we know that $r = 40$ and $\theta = \frac{7\pi}{6}$ , then the rectangular form of the number is:

$a = 40\cdot \cos \frac{7\pi}{6}$

$a = -20\sqrt{3}$

$b = 40\cdot \sin \frac{7\pi}{6}$

$b = -20$

The rectangular form of $z=40\cdot\left(\cos \frac{7\pi}{6}+i\,\sin \frac{7\pi}{6}\right)$ is $z = -20\sqrt{3}-i\,20$ . The correct answer is C.
