Answer:

Step-by-step explanation:

(0,1) (1, -3)

(-3 - 1)/(1 - 0)= -4/1= -4

y - 1 = -4(x - 0)

y - 1 = -4x + 0

y = -4x + 1: equation

slope: -4

y int: 1 or (0, 1)

8. A.

9. B.

10. C.

Step-by-step explanation:

6. 9 + (12 - 10)

12 - 10 = 2

9 + 2 = 11

7. (20 - 15) x 2

20 - 15 = 5

5 x 2 = 10

8. 10 ÷ 5 + 7

10 ÷ 5 = 2

2 + 7 = 9

9. 6 + 2 x 3

2 x 3 = 6

6 + 6 = 12

10. (2 x 4) + 8

2 x 4 = 8

8 + 8 = 16

From a radar station, the angle of elevation of an approaching airplane is 32.5 degree. The horizontal distance between the plan

denis23 [38]

Answer: 42.21 km

Step-by-step explanation:

We can solve this using trigonometry, since we have the following data:

$\theta=32.5\°$ is the the angle of elevation

$d=35.6 km$ is the horizontal distance between the plane and the radar station

$x$ is the hypotenuse of the right triangle formed between the radar station and the airplane

Now, the trigonometric function that will be used is <u>cosine</u>:

$cos\theta=\frac{d}{x}$ because $d$ is the adjacent side of the right triangle

$cos(32.5\°)=\frac{35.6 km}{x}$

Finding $x$ :

$x=\frac{35.6 km}{cos(32.5\°)}$

$x=42.21 km$
