A road has a 10% grade, meaning increasing 1 unit of rise to every 10 units of run.
fenix001 [56]

The grade is the ratio of rise to run, i.e. the slope aka the tangent.

\tan \theta = \dfrac{1}{10}

\theta = \arctan 0.1 \approx 5.711^\circ

Answer: (a) 6 degrees

For part b, the road is the hypotenuse c of a right triangle whose tangent of the small angle is 1/10.    The height h or rise is the side opposite the small angle.

\sin\theta = \dfrac h c

h = c \sin \theta

We could just take the sine of the angle we got but let's get it from the tangent exactly.

\cos^2 \theta + \sin ^2 \theta = 1

Dividing by squared cosine

1 + \tan ^2 \theta = 1/\cos^2 \theta = 1/(1- \sin^2 \theta)

(1- \sin^2 \theta) = 1/(1 + \tan^2 \theta)

\sin^2 \theta = 1 - 1/(1 + \tan^2 \theta)

\sin^2 \theta = 1 - 1/(1 + (1/10)^2) = 1-1/(101/100) = 1/101

h = c \sin \theta = 2 \sqrt{1/101} \approx 0.199

Answer: (b) Rise of 0.199 km

What are the coordinates of the point is 1/4 of the way from A (-6, -3) to B (6, 1)?
Amiraneli [1.4K]

Answer:

(-3, -2)

Step-by-step explanation:

To find the coordinates of the point is 1/4 of the way from A (-6, -3) to B (6, 1), we are going to be using the midpoint formula, which states that:

The midpoint is at (\frac{x_{1} +x_{2} }{2}, \frac{y_{1} +y_{2} }{2}). Where:

(x_{1}, x_{2}) = (-6, 6)

(y_{1}, y_{2}) = (-3, 1)

Then, the midpoint is at:

(\frac{-6 +6 }{2}, \frac{-3+1}{2}) = (0, -1)

Now, to find the coordinates of the point that is 1/4 of the way, we are going to calculate the midpoint between the point 'A' and the midpoint previously caculated, as follows:

(x_{1}, x_{2}) = (-6, 0)

(y_{1}, y_{2}) = (-3, -1)

⇒ (\frac{-6 +0}{2}, \frac{-3-1}{2}) = (-3, -2)

Therefore, the point is 1/4 of the way from A to B is:  (-3, -2)
