Answer:

The answer is 17 km due north.

Step-by-step explanation:

24 km due north subtracted by 7 km east

Put north because it was first (this was based on a rule).

The distance between the final position to the initial position will be 25 km.

It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometry function.

The Pythagoras theorem states that the sum of two squares equals the squared of the longest side.

The Pythagoras theorem formula is given as

H² = P² + B²

Pierre walks 24 km due north and then 7 km due east. Then the distance between the final position to the initial position will be

H² = 24² + 7²

H² = 576 + 49

H² = 625

H² = 25²

H = 25 km

The distance between the final position to the initial position will be 25 km.

Answer:

x=7

Step-by-step explanation:

Hey There!

I believe they want us to use law of sines

To do so we need to find the missing angle

180-90-25=65

now we set up and equation

[tex]\frac{x}{sin25} =\frac{15}{sin65}[/tex]

step 1 multiply each side by sin25

[tex]x=\frac{15sin25}{sin65} \\x=6.994614872[/tex]

it says to round to the nearest tenth so we can conclude that x=7

Answer:

y = (1/3)x + 2

Step-by-step explanation:

The equation of a straight line is given by:

y = mx + b, where y and x are variables, m is the slope of the line, that is the ratio of the change in vertical distance to horizontal distance while b is the y intercept of the graph.

From the graph, we can see that the y intercept (where the graph touches the y axis) is 2. Hence b = 2

Also, the slope (m) = change in y / change in x = 1 / 3

The equation of the line is:

y = (1/3)x + 2

Answer:y = (1/3)x + 2

Answer:

3x+4y+7y = 3x + 11 y

Step-by-step explanation:

We need to simplify the given expression i.e.

3x+4y+7y

We know that, the like terms gets add up i.e. the sum of 4y and 7y equals 11 y

So,

3x+4y+7y = 3x + 11 y

Hence, the final simplification should be 3x + 11 y.

Answer:

  an = 5 +3(n -1)

Step-by-step explanation:

The n-th term of an arithmetic sequence is ...

  an = a1 +d(n -1)

Here, you have first term a1=5 and common difference d=8-5=3, so the n-th term is ...

  an = 5 +3(n -1)

_____

If you like, you can simplify this to ...

  an = 5 +3n -3

  an = 3n +2

Answer:

43.94?

Step-by-step explanation:

I think if you use inverse cos you should get the correct number. So, to find cos, you need to know the adjacent side and the hypotenuse. Here, the reference angle would be the person holding the kite. The distance from the person to the barn is the adjacent side, which is 18. The string of the kite, I assume, would be 25.

cos(∅) = [tex]\frac{18}{25}[/tex]

cos(∅) = 0.72

cos⁻¹(0.72) = 43.94

I don't know if that's what you're looking for, but... If it's not correct, lmk so I can rewrite it. :)
