The height of the pole = 129.3 ft

sin 36° = height of pole/ hypotenuse
hypotenuse = 220 ft

the height of the pole = 220 sin 36° = 129.3 ≈ 129 ft

The answer would be 129 ft.

Solution:
Given: the height of the pole = 129.3 ft
sin 36° = height of pole/ hypotenuse
hypotenuse = 220 ft

the height of the pole = 220 sin 36°
 = 129.3
≈ 129 ft

kari74 [83]

So we need to convert 0.75 feet to inches.

0.75 feet = 9 inches

Then we divide 9 by how many hours are in a day: 24

9/24 = 0.375

The raindrop vine can grow up to 0.375 inches per hour.

An equation is formed of two equal expressions. The equation of the exponential graph is A=100(0.5)ˣ.

<h3>What is an equation?</h3>

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

The equation of an exponential function is given by the formula,

y = A (B)ˣ

Now as per the graph, there are two points (1, 50) and (2, 25).

50 = A (B)¹

50 = AB

A = 50/B

Substitute another point in the equation,.

25 = A (B)²

25 = (50/B) (B)²

25 = 50B

B = 0.5

Substitute the value of B,

A = 50/0.5 = 100

Hence, the equation of the exponential graph is A=100(0.5)ˣ.
