Atree casts a shadow that is 24 feet in length. if the angle of elevation is 30 degrees, which of the following best represents the height of the tree?

a. 10.7 ft
b. 12.2 ft
c. 9.4 ft
d. 13.9 ft

The answer is D) 13.9

Step-by-step explanation:

Since the angle of elevation is adjacent to the length of 24, than to find the height you have to use tangent. so you take your calculator in DEGREES mode and enter tan(30) which gives you =0.5773502692... than you would multiply by 24 which gives you the height =13.8564

Sorry if I wasn't specific enough, ask if you want more help. I am sure this is the right answer

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.

step-by-step explanation:

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
