<span>get their dot product, if the dot product is 0, then they're orthogonal (perpendicular).
also keep in mind that, if two vectors bear the same slope, namely <a,b> and <c,d> and the simplified slope b/a is the same value as d/c, then they're parallel vectors.</span>
Answer:
D = 120° , E = 30° , F = 30°
Step-by-step explanation:
Let D = 4x
Let E&F = x
4x + x + × = 180°[angles in triangle is 180°]
6x = 180°
x = 180/6
x = 30°
E = 30°
F =30°
D =4(30°)
=120°

Answer:
72.4%
Step-by-step explanation:
The essay is 25% of your grade, and the rest is 75% of your grade.
25 (3.3/4) + 75 (0.69) ≈ 72.4
Radius is 16, that’s all I know
Answer:
Domain: all real values of x
Range: all real values of y
Translation depends on the parent function
If the first function was:
y = cuberoot(x)
Then translation is:
Vertical translation 1 unit downwards
