Answer:
4(x-1/2)^2+0
Step-by-step explanation:
I used the formula (b/2)^2
Given :
A building is of unknown height. At a distance of 400 feet away from the building .
An observer notices that the angle of elevation to the top of the building is 35º and that the angle of elevation to a poster on the side of the building is 15º .
To Find :
How far is the poster from the roof of the building .
Solution :
Height is given by :

( Here ,
is angle of elevation )
So , height of tower :

For height of poster :

Therefore , distance of poster from the roof of the building is :

Hence , this is the required solution .
Answer:
11.5+5.5+13
Step-by-step explanation:
Answer:
(y+1)^3
Step-by-step explanation:
When dividing powers, subtract them. Therefore, 5-2 = 3. So, (Y+1)^5/(Y+1)^2 = (Y+1)^3
