Answer:

Explanation:
Angle of depression = 
b = Height of building = 42 feet

p = Distance from the car to the base of the building
From the trigonometric identities we get

The distance from the car to the base of the building is
.
Answer:An ice age is a period of colder global temperatures and recurring glacial expansion capable of lasting hundreds of millions of years.
Explanation:These global cooling periods begin when a drop in temperature prevents snow from fully melting in some areas. The bottom layer turns to ice, which becomes a glacier as the weight of accumulated snow causes it to slowly move forward. A cyclical pattern emerges in which the snow and ice traps the Earth’s moisture, fueling the growth of these ice sheets as the sea levels simultaneously drop.
Answer:
$540, you just multiply $50 x those 6 months=$300 then you multiply $40 x those other 6 months and you get $240 and then you add 240+300=$540
Explanation:
You just have to go over it over and over until you can memorize it and remember where everything is<span />
Answer:
Aquatic animals and organisms thrive in coral reef habitats/ecosystems. The biodiversity of different organisms (like fish) are abundant because of the habitats (like anemone), algae, and phytoplankton that live off the area. The destruction of the coral reef by polution can cause a disturbance in the balance of life. For example, the bacteria and algae (autotrophs) that live off the sides of pieces of coral would die off causing the fish and other things that way them to die off and then the fish that consume those animals would die off.
In shorter terms: the physical damage would throw off the balance of the food web/food chain and would destroy habitats of thousands of organisms causing them to die off.
Hope this helps! :D
