Un topografo situado en un punto c localiza dos puntos a y b en los lados opuestos de un lago . Si el punto c esta situado a 5km de a y 8 km de b y ademas el angulo formado en el punto c es de 36 grados . Calcular el ancho del lago

Answers

The width of the lake is approximately 4.93 kilometers.

To calculate the width of the lake, you can use trigonometry. You have a triangle with one side of 5 km (from point C to point A), another side of 8 km (from point C to point B), and an included angle of 36 degrees at point C.

You can use the law of cosines to find the third side, which is the width of the lake (let's call it "x"). The law of cosines states:

$c^2 = a^2 + b^2 - 2ab * cos(C)$

Where:

c is the side you want to find (the width of the lake, in this case).

a is the side opposite to angle A (5 km).

b is the side opposite to angle B (8 km).

C is the included angle at point C (36 degrees).

So, plug in the values:

$x^2 = 5^2 + 8^2 - 2 * 5 * 8 * cos$ (36 degrees)

Now, you can solve for x:

$x^2 = 25 + 64 - 80 * cos$ (36 degrees)

$x^2 = 89 - 80 * cos$ (36 degrees)

Now, you'll need to calculate the cosine of 36 degrees, which is approximately 0.809.

$x^2 = 89 - 80 * 0.809\nx^2 = 89 - 64.72\nx^2 = 24.28$

Now, take the square root of both sides to find the width of the lake:

x ≈ √24.28

x ≈ 4.93 km

So, the width of the lake is approximately 4.93 kilometers.

Solve the equation x/4+3=19 and verify the solution

Answers

x divided by 4+3 (7) has to equal 19 so take 19 and multiply is by 7 and you get 133 which is what x is

Final answer:

The solution to the equation x/4 + 3 = 19 is x = 64. This is verified by substituting x = 64 back into the original equation, simplifying, and confirming the equation holds true.

Explanation:

To solve the equation x/4 + 3 = 19, we first subtract 3 from both sides of the equation. This gives us x/4 = 19 - 3, or x/4 = 16. Next, we multiply both sides of the equation by 4 to solve for x, which gives us x = 16 * 4 or x = 64.

To verify the solution, we substitute x = 64 back into the original equation: 64/4 + 3 = 19. Simplifying the left side gives us 16 + 3 = 19, which is equivalent to the right side. Therefore, the solution x = 64 is correct.

Which value of a correlation coefficient represents the strongest relationship between the two variables in a given linear regression model? a) -0.94
b) 0
c) 0.5
d) 0.91

Answers

Answer: a) -0.94

Explanation:

The closer r gets to +1 or -1, the stronger the linear relationship will be.

If r is really close to +1, then we have a strong positive linear relationship. If r is close to -1, then we have a strong negative linear relationship.

Of the four choices given, we see that r = -0.94 is the closest to either endpoint mentioned. The next closest is r = 0.91

Put another way, we're looking for the r value that is furthest way from 0, but also that makes the inequality $-1 \le r \le 1$ true. Choice A fits that description best.

Final answer:

The value of -0.94 represents the strongest relationship between the two variables in a given linear regression model.

Explanation:

The value of a correlation coefficient ranges from -1 to 1. The closer the value is to -1 or 1, the stronger the relationship between the two variables in a linear regression model. Therefore, the value of "-0.94" represents the strongest relationship among the given options. A negative correlation coefficient indicates an inverse relationship, meaning that as one variable increases, the other variable decreases.
