Answer:
5.87
Step-by-step explanation:
The tangent relation tells you ...
Tan = Opposite/Adjacent
tan(50°) = 7/BC
BC = 7/tan(50°)
BC ≈ 5.87
<span>diff(x^2-11*x+24, x) = 2*x - 11
solve(2*x-11 = 0)
x = 11/2
y = (11/2)^2-11*(11/2)+24 = - 25/4
Vertex = (11/2, - 25/4)</span>
(Distribute the 3)
6x +15 <span>≥ 2(x + 6)
(Distribute the 2)
6x + 15 </span><span>≥ 2x +12
(subtract 2x from both sides)
4x + 15 </span><span>≥ 12
(subtract 15 from both sides)
4x </span><span>≥ -3
(divide by 4x on both sides)
x </span>≥ -0.75
Hope that helped!
