Answer:
50ft
Step-by-step explanation:
let x=height of tree.
AB/DE = BC/EC
The ratio is == x/5 =120/12
x/5 = 10
x = 50
Height of tree is 50 ft.
Answer:
24x4=k
Step-by-step explanation:
because if it says its 4 TIMES it is hinting that you have to multiply
Check the picture, notice the domain in red.
recall that the domain is the values for the x-coordinate, whilst the range is the values for the y-coordinate.
Remember that transformation between Cartesian and polar system are:
x=r*cos(α)
y=r*sin(α)
From this we can conclude that:
r=√(x^2 + y^2)
Using trigonometry transformations we can write:
r=sin(2α) = 2sin(α)cos(α)
Now we can multiply both sides with r^2:
r^3 = 2(r*sin(α))*(r*cos(α))
Now using some replacements we can write:
(x^2 + y^2)^(3/2) = 2*x*y
