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.

O. Find the domain and range of each of the three restricted functions.
Orlov [11]

The domain and range of the functions sin x, cos x, and tan x will be (-∞, ∞) and [-1, 1], (-∞, ∞) and [-1, 1], and R - (2n + 1)π/2 and (-∞, ∞) respectively.

<h3>What are domain and range?</h3>

The domain means all the possible values of x and the range means all the possible values of y.

The three restricted functions are given below.

f(x) = sin (x)

f(x) = cos (x)

f(x) = tan (x)

Then the domain of the three restricted functions will be

The domain of sin x will be (-∞, ∞).

The domain of cos x will be (-∞, ∞).

The domain of tan x will be R - (2n + 1)π/2.

Then the range of the three restricted functions will be

The range of sin x will be [-1, 1].

The range of cos x will be [-1, 1].

The range of tan x will be (-∞, ∞).

The graph is given below.

More about the domain and range link is given below.

What is the slope of the line through (2,-2)(2,−2)left parenthesis, 2, comma, minus, 2, right parenthesis and (9,3)(9,3)left par
user100 [1]

Answer:

5/7

Step-by-step explanation:

We have two points ( 2,-2) and (9,3)

We can find the slope using the slope formula

m = ( y2-y1)/(x2-x1)

   = ( 3- -2)/( 9-2)

   = ( 3+2)/(9-3)

   = 5/7
