A virus has infected 400 people in the town and is spreading to 25% more people each day.

NeTakaya

Answer:

N = 400(1.25^t); 3725

Step-by-step explanation:

25% more is 125% of the previous, which is 1.25

N = 400(1.25^t)

t = 10

N = 100(1.25^10)

N = 3725.290298

An airplane pilot over the Pacific sights an atoll at an angle of depression of 5 . At this time, the horizontal distance from t

Aleonysh [2.5K]

Answer:

404.98 m

Step-by-step explanation:

The angle of depression is 5°

The horizontal distance from the airplane to the atoll is 4629 meters.

We need to find the height of the plane.

If we consider a triangle. 4629 meters will be the base and angle is 5°. Let h is the height of the plane. Using trigonometry to find it :

$\tan\theta=\dfrac{x}{4629 }\\\\\tan(5)=\dfrac{x}{4629 }\\\\x=\tan(5)\times 4629 \\\\x=404.98\ m$

So, the height of the plane is 404.98 m.
