erma4kov [3.2K]

Answer:

The situations 1 and 2 describes an equal difference over an equal interval.

Step-by-step explanation:

1. A sunflower grows at a rate of 3.5 cm per day, for the first 28 days.

Here, the growth of the sunflower per day is uniform i.e. 3.5 cm.

2. After the car is purchased the value of a car depreciates at a rate of 15% per year.

Nonamiya [84]

Answer:

Height of the kite from the ground is 29.2 feet.

Step-by-step explanation:

For better explanation of the solution, see the figure attached :

The angle formed by the height of kite to that of the surface of the ground is right angle.

⇒ m∠ABC = 90°

Let angle of elevation be θ

Now, to find height of the kite : find length of AB

In right angled triangle ABC , using tan rule, we have\tan\theta=\frac{Perpendicular}{Base}\\\\\tan36^{\circ}=\frac{AB}{BC}\\\\\implies \tan36^{\circ}=\frac{AB}{40}\\\\\implies AB=0.73\times 40\\\\\bf\implies AB=29.2\thinspace{ feet}

Hence, Height of the kite from the ground is 29.2 feet.
