Answer:
Point B
Step-by-step explanation:
a point of tangency on a circle is where an outside line touches the outer circle at one point (the outside line touching it only once is what makes that line a tangent) so in this case the point of tangency is Point B

Answer:
83.79 kJ
Step-by-step explanation:
The potential energy is the product of weight and height, where weight is in newtons.
PE = Mgh = (190 kg)(9.8 m/s^2)(45 m) = 83,790 J
You seem to be saying that Y=4/X+SQRT X +0.2 -5X, and that x is given as 4/5. To evaluate <span>Y=4/X+SQRT X +0.2 -5X, replace each occurrence of x with 4/5:
y = 4 / (4/5) + sqrt(4/5) + 0.2 - 5(4/5)
= 5 + 2 / sqrt(5) + 0.2 - 4
Can you simplify this further?
