An airplane spots the floating debris at an angle of depression of 15 degrees. If the plane is at an altitude of 3000. Feet, wha

hodyreva [135]

Answer:

11196.15 km

Step-by-step explanation:

Consider the attached diagram

If the Airplane is at point A and the floating debris at point C, we want to determine the horizontal distance |AB| before they fly over it.

Using trigonometry

$Tan \alpha =\frac{Opposite}{adjacent} \\Tan 15 =\frac{3000}{|AB|}$

Cross multiply

|AB|X Tan 15 =3000

|AB| = $\frac{3000}{Tan 15}$ =11196.15 km

Therefore, the horizontal distance |AB| before they fly over it is 11196.15 km

The table shows four numeric expressions. Which expression is an integer when it's evaluated?

baherus [9]

Answer:

Option C) G.

Step-by-step explanation:

Verify each expression

case E) we have

$3.8+0$

Any number plus zero equals the original number (Identity property of addition)

$3.8+0=3.8$ -----> is a decimal number

case F) we have

$0+0.5$

Any number plus zero equals the original number (Identity property of addition)

$0+0.5=0.5$ -----> is a decimal number

case G) we have

$-8+0$

Any number plus zero equals the original number (Identity property of addition)

$-8+0=-8$ -----> is an integer

case H) we have

$9/0$

division by zero is undefined
