In the calm waters of an inlet, Manon's boat moves with a velocity (speed and direction) vector \vec{b_1} = (3,4) b 1 =(3,4)

andrew-mc [135]

Answer with Step-by-step explanation:

We are given that

$b_1=(3,4)$

$b_2=(1,1)$

We have to find the speed of river's current and the direction of current flowing.

$b=b_2-b_1=(1,1)-(3,4)=(-2,-3)$

Speed of river's current= $\mid b\mid$

Speed of river's current= $\sqrt{(-2)^2+(-3)^2}$

Speed of river's current= $\sqrt{13} m/s$

By using the formula

$\mid r\mid =\sqrt{x^2+y^2}$

Direction of current flowing, $\theta=tan^{-1}(\frac{y}{x})$

$\theta=tan^{-1}(\frac{-3}{-2})=56.3^{\circ}$

The angle lies in third quadrant therefore

$\theta=180+56.3=236.3^{\circ}$

How do i do time and distance

larisa [96]

Answer:

To solve for speed or rate use the formula for speed, s = d/t which means speed equals distance divided by time. To solve for time use the formula for time, t = d/s which means time equals distance divided by speed.

Convert the following units of time. a. 5 years to days b. 8 weeks to days c. 7 days to weeks d. 336 hours to seconds e. 12 hour

AysviL [449]

Answer:

A. 1,825 days

B. 56 days

C. 1 week

D. 1,209,600 seconds

E. 43,200 seconds

F. 2 hours

Step-by-step explanation:

A. 1 year = 365 days, then

5 years = $5\cdot 365$ days = 1,825 days.

B. 1 week = 7 days, then

8 weeks = $8\cdot 7$ days = 56 days.

C. 7 days = 1 week.

D. 1 hour = 3,600 seconds, then

336 hours = $336\cdot 3,600$ seconds = 1,209,600 seconds.

E 12 hours = $12\cdot 3,600$ seconds = 43,200 seconds.

F. 3,600 seconds = 1 hour, then

7,200 seconds = $\dfrac{7,200}{3,600}$ hours = 2 hours.

HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Gre4nikov [31]

Answer:

93° (to the nearest degree)

Step-by-step explanation:

sum of the interior angles of a triangle = 180°

Find angle C first, then subtract angle C and angle B from 180° to find angle A.

Use the sine rule $\frac{sinA}{a}=\frac{sinB}{b}=\frac{sinC}{c}$ to find angle C:

Therefore,

$\frac{sinB}{b}=\frac{sinC}{c}$

$\frac{sin38}{9}=\frac{sinC}{11}$

angle C = 48.80523914...°

Angle A = 180 - 38 - 48.80523914...°

= 93.19476086..°

= 93° (to the nearest degree)
