Jared is standing on the roof of a 100 meter building doing some surveying. He spots a delivery truck at an angle of depression
just olya [345]
1st :The angle of depression 30° = the angle of elevation (from the truck to the height of the building.

2nd :
cos 30° = (adjacent side)/(hypotenuse)
cos 30° = x/100, but cos 30°= (√3)/2

(√3)/2 = x/100 and x = (100√3)/2

and x = (50.√3) = 86.60 m

ASAP!!! Which of these graphs could represent an exponential <br> relation (Explain)
Margarita [4]

Answer:

B. looks like the best answer that fits this question.

If i'm wrong then my fault.

Step-by-step explanation:

When looking at choice (B) you can see it started at a decreasing point but slowly growing. Exponential relations are images or equations that describe growth and they always have the same function. If you look at the other choices you see that they either increase but then decrease or they don't match the formula for (exponential relations).

That's as good as I can do I dont knw if this what ur teacher is looking for but I tried :/
