Answer:

See below in bold.

Step-by-step explanation:

Ship's vector:

Horizontal component = 30 cos 30  = 25.98.

Vertical component = 30 sin(-30) = -15.

So it is <25.98, -15).

The current's vector:

Horizontal component =  5 sin 20 = 1.71.

Vertical component = 5 cos 20 = 4.7.

So it is <1.71, 4.7>.

Answer:

Step-by-step explanation:

Resultant R of the two vectors is

R^2=a^2+b^2+2abcos\theta

R^2=30^2+5^2+2\left ( 30\right )\left ( 5\right )cos\theta

Where \thetais the angle between Two vectors which is 100^{\circ}[/tex]

R^2=900+25+2\times 30\times 5\times cos100

R^2=925-52.094

R=29.544 miles per hour

and it makes an angle \phiwith 30 miles/hr vector

tan\phi =\frac{5}{30}

\phi =tan^{-1}\frac{1}{6}

\phi =9.462^{\circ}

i.e.it makes an angle of 20.538 South of east with horizontal

Answer:

40°

Step-by-step explanation:

m\angle A + m\angle B = 180\degree

(Linear pair angles)

140\degree + m\angle B = 180\degree

m\angle B = 180\degree -140\degree

m\angle B = 40\degree

HELP ASAP AND GETS SOME POINTS AND BRAINLEST!!!!
guajiro [1.7K]

Answer:

9x² + 28x - 32

Step-by-step explanation:

Given

(9x - 8)(x + 4)

Each term in the second factor is multiplied by each term in the first factor, that is

9x(x + 4) - 8(x + 4) ← distribute both parenthesis

= 9x² + 36x - 8x - 32 ← collect like terms

= 9x² + 28x - 32

Alex787 [66]

This means 339 calories burned while combining diet with 1 hour of exercise

Step-by-step explanation:

Given the functions as:

f(x)=2x+210  

g(x)=2x+125 then

(f+g)(x) = 2x+210 +2x+125 = 4x +335

(f+g)(1) = 4(1)+335

           =339

This means 339 calories burned while combining diet with 1 hour of exercise
