The right answer is Option B.

Step-by-step explanation:

Let,

Age of Nora = x

Age of Damon = y

According to given statement;

x = 3y      Eqn 1

In 8 years;

x+8 = 2(y+8)     Eqn 2

Putting value of x from Eqn 1 in Eqn 2

3y+8=2(y+8)\\3y+8=2y+16\\3y-2y=16-8\\y=8

Damon is now 8 years old.

In 8 years, he will be = 8+8 = 16 years old

Damon will be 16 years old in 8 years.

The right answer is Option B.

What do you notice about each solution? : 
Picture 1 - They never intersect/touch.
Picture 2 - They are intersecting.
Picture 3 - They are on top of each other.

What do you notice about the graphs for each set of equations? : 
Picture 1 - The lines are parallel.
Picture 2 - They are intersecting.
Picture 3 - They are on top of each other. (otherwise known as coincident lines).

What do you notice about each set of equations? : 
Picture 1 - They have the same slope but different y-intercepts.
Picture 2 - Both the slopes and y-intercepts are different for each equation.
Picture 3 - They have the same slope and same y-intercept.

What generalization can you make? : 
Picture 1 - When equations have the same slope but different y-intercepts they will be parallel when graphed.
Picture 2 - When the equations have different slopes and different y-intercepts they will be intersecting.
Picture 3 - When the equations are the same they will be coincident lines when graphed.

Answer:

<em>approximately 52.752 or 16.8 </em>\pi<em />

Step-by-step explanation:

  1. First find the radius

a) we know the diameter so we can use the formula r=d/2 to solve for the radius

b)16.8/2 =8.4

  2. Then we substitute into the equation

a)2\pir

b)2\pi(8.4)

c)52.752 or 16.8 \pi

Ab= <br> round to the nearest hundredth
mestny [16]
Cos = adjacent / hypotenuse

cos 25° = 4 / AB

cos 25° • AB = 4 / AB • AB

AB cos 25° ÷ cos 25° = 4 ÷ cos 25°

AB = 4/cos 25°

AB = 4.41 (nearest hundredth)
