No, the tangent line needs to be against the circle from where it leaves. This is just a straight up right angle.

Answer:

Option B is correct .i.e., Yes.

Step-by-step explanation:

We are given with length of three line segments .

10 , 6 and 8.

We use the result to check if one line is tangent or not.

Result: Tangent is perpendicular to radius at point of contact.

So if AB is tangent than ABO form a right angled triangle and AB is right angle.

AO² = 10² = 100

AB² + BO² = 8² + 6² = 64 + 36 = 100

Since AO² = AB² + BO²

According to Pythagoras theorem,

∠B is 90° which implies AB is tangents to circle.

Therefore, Option B is correct .i.e., Yes.

Sever21 [200]

Answer:

The air is .6m^3

Step-by-step explanation:

The volume of a cube is

V = s^3 where s is the side length

The volume of the tank is

V = 1^3 = 1 m^3

The volume of the water is 1 by 1 by .4

V = l*w*h

   = 1 *1*.4

   = .4 m^3

The difference must be filled by air

1- .4 = .6 m^3

The air is .6m^3

The lifespan of a 60-watt lightbulb produced by a company is normally distributed with a mean of 1450 hours and a standard devia
Flura [38]
To evaluate the probability that the lifespan will be between 1440 and 1465 hours will be given by:
P(1440<x<1465)
using the z-score formula we obtain:
z=(x-μ)/σ
where:
μ=1450
σ=8.5
hence
when x=1440
z=(1440-1450)/8.5
z=-1.18
P(z<-1.18)=0.1190

when x=1465
z=(1465-1450)/8.5
z=1.77
P(z<1.77)=0.9625

hence:
P(1440<x<1465)
=0.9625-0.1180
=0.8445
