11) To approach a runway, a pilot must begin a 10° descent starting from a height of 0.38 miles above the ground. At

the start of his approach, how far, d, is the plane from the

runway to the nearest tenth of a mile?

the plane 2.2 miles away from the runway

Step-by-step explanation:  

Given the data in the question and as illustrated in the image below;

from the image, using trigonometric ratio;

SOH CAH TOA

sin = opposite / hypotenuse

sin10° = 0.38 / x

xsin10° = 0.38

x = 0.38 / sin10°

x = 0.38 / 0.173648

x = 2.1883 miles  ≈ 2.2 miles     { the nearest tenth of a mile }

Therefore, the plane 2.2 miles away from the runway

the correct answer is b) histograms can be used to exhibit the shape of distributions. this is because histograms count the frequency of each possible answer, so one is able to see which results are more common and which are less common.

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1
