Answer:
-1/4
Step-by-step explanation:
y2 - y1 / x2 - x1
-9 - (-6) / 3 - (-9)
-3/12
= -1/4
Answer:
The angle of elevation is about 27°
Step-by-step explanation:
Let's view this case in the form of a right angled triangle. With the original height as the opposite side to the elevation angle and the shadow length as the adjacent side.
Let x represent the original height
2x is the length of shadow
And θ the angle of elevation
Applying trigonometry;
Tan θ = opposite/adjacent = original height/shadow length
Substituting the values;
Tan θ = x/2x
Tan θ = 1/2
θ = taninverse(1/2)
θ = 26.56505117707
θ ≈ 27°
Elevation angle is approximately 27°
780:2 is the answer, i hope this works
Answer:
5/3, 14/9, 41/27
Step-by-step explanation:
f(x) = (⅓)x + 1
x=0 = 2
x1 = (⅓)(2) + 1
= ⅔ + 1
x1 = 5/3
x2 = (⅓)(5/3) + 1
= 5/9 + 1
x2 = 14/9
x3 = (⅓)(14/9) + 1
= 14/27 + 1
x3 = 41/27
