Answer:

Collinear points are points all in one line and non collinear points are points that are not on one line. Below points A, F and B are collinear and points G and H are non collinear. Coplanar points are points all in one plane and non coplanar points are points that are not in the same plane.

Ms. Fry started walking as her New Year’s resolution. She calculated that she can walk a 1/2 mile in 1/4 of an hour. What is her

Natalija [7]

Answer:

2 miles per hour

Step-by-step explanation:

1/4 x 4 = 1

1/2 x 4 = 2

1/4 is a quarter of 100, so you have to multiply it by 4 to get 100% or 1.

So 1/2 x 4 is 2, which is the mph.

2. The Geo Air pilot is looking at SCCA from the plane. From the aircraft the angle of depression is 17 degrees. If the plane is

lana66690 [7]

Answer:

The distance from the plane to SCCA is 34,203.0 feet approximately, and the horizontal distance is 32,708.5 feet approximately.

Step-by-step explanation:

You can draw a right triangle like the one shown in the figure attached, where:

x: horizontal distance.

y: distance from the plane to SCCA.

You can calculate x as following:

$tan\alpha=\frac{opposit}{adjacent}$

Where:

$\alpha=17\°\\opposite=10,000\\adjacent=x$

Substitute and solve for x:

$tan(17\°)=\frac{10,000}{x}\\\\x=\frac{10,000}{tan(17\°)}\\\\x=32,708.5ft$

You can calculate y as following:

$sin\alpha=\frac{opposit}{hypotenuse}$

Where:

$\alpha=17\°\\opposite=10,000\\hypotenuse=y$

Substitute and solve for y:

$sin(17\°)=\frac{10,000}{y}\\\\y=\frac{10,000}{sin(17\°)}\\\\y=34,203.0ft$
