Conic sections are defined using a directrix (<span>a fixed line used in describing a curve or surface) and a focus, and those are: parabola, ellipse, and hyperbola. </span>
Answer:
sin θ = 24/25.
Step-by-step explanation:
Cos θ = 7/25 so we have a right triangle with adjacent side = 7 and hypotenuse = 25.
So the opposite side = sqrt ( 25^2 - 7^2) ( By Pythagoras)
= sqrt 576
= 24 .
Therefore sin θ = 24/25.
Answer:
-2.5
Step-by-step explanation:
5b - b - 1 ≥ -11
4b - 1 ≥ -11
+1 +1
4b ≥ -10
4/4 -10/4
b ≥ -2.5
