Q1a.

Midpoint formula :

$m = ( \frac{x1 + x2} {2} \: \frac{y1 + y2}{2} )$

$m = ( \frac{ - 2 + 4}{2} \: \frac{3 + 6}{2} )$

$m = (1 \: \frac{9}{2} ) \: or \: (1 \: 4.5)$

Q2a.

Distance Formula :

$d = \sqrt{(x2 - x1) ^{2} + (y2 - y1) ^{2} }$

$d = \sqrt{ ( - 2 - ( - 6)) ^{2} + (1 - ( - 2)) ^{2} }$

$d = \sqrt{ {4}^{2} + {3}^{2} }$

$d = \sqrt{16 + 9}$

$d = \sqrt{25}$

$d = 5 \: units$

Marrero is in a hot-air balloon that is 600 feet above the ground, where he can see two people.

Vlad1618 [11]

Answer: The distance from the person on the ground to the bottom of the hotair balloon is 1,649 ft

Step-by-step explanation: Please refer to the attached diagram

From the diagram, the hotair balloon is labelled B. If Marero looks down and forms an angle of depression of 20°, that means he is forming an angle of 70° to point C where one of the two persons are standing. Point B is an angle of 70° (point A cuts point B at a perpendicular, that is, 90°)

With these we can now use the trigonometrical ratio of tangent to calculate the distance marked x on the diagram.

Tan B = opposite/adjacent

Tan 70 = x/600

When we cross multiply, we now have

Tan 70 × 600 = x

2.7475 × 600 = x

1648.5 = x

Rounded to the nearest feet

x = 1,649 feet
