A 6.2m tree casts a shadow across the playground. If the angle of elevation is 43 degrees, the length of the shadow is

Step-by-step explanation:

Using trigonometry, we can apply basic trig rules for a right triangle. Since the tree is perpendicular with the ground, it forms a with the ground.

Therefore,

.

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.
