A ship is sailing on the sea. It travels 50 miles at 60° to the horizontal. Then the ship travels 90 miles at 30° to the horizon
pav-90 [236]

Answer:

(25\sqrt{3}+45)\ miles

Step-by-step explanation:

we know that

The total vertical distance (total miles North) traveled is equal to

d=50sin(60^o)+90sin(30^o)

Remember that

sin(60^o)=\frac{\sqrt{3}}{2}

sin(30^o)=\frac{1}{2}

substitute

d=50(\frac{\sqrt{3}}{2})+90(\frac{1}{2})

d=(25\sqrt{3}+45)\ miles

Write an equation in slope intercept form for the graph of the line.​
olganol [36]

Answer:

  • y = 2x - 3

Step-by-step explanation:

<u>Slope intercept form:</u>

  • y = mx + b, where m - slope, b - y-intercept

<u>Take two points from the graph:</u>

  • (2, 1) and (3, 3)

<u>Find the slope:</u>

  • m = (3 - 1)/(3 - 1) = 2/1 = 2

<u>Find the y-intercept using point (2, 1) and the equation above:</u>

  • 1 = 2*2 + b
  • b = 1 - 4
  • b = -3

<u>The line is:</u>

  • y = 2x - 3

Fiona wrote out the description of each step for her multiplication of the binomial and trinomial (2x – 3)(5x2 – 2x + 7).
Valentin [98]

Answer:

Step 2

Step-by-step explanation:

Fiona did mistake step 2.

Use the distributive property to multiply -3 times each term in the trinomial.

The correct result is

-3(5x^2 - 2x + 7) = -15x^2 + 6x - 21

Fiona written -6x instead of + 6x.

That's the error.

The answer is "Step 2"

Hope you will understand the concept.

Thank you.
