Answer:

12.78 units

Step-by-step explanation:

The formula for arc length =

2πr × θ/360

From the question:

θ = 122°

r = 6 units

Therefore, the arc length =

2 × π × 6 × (122/360)

= 12.775810125 units

Approximately to the nearest hundredth = 12.78 units

Therefore, the length of arc CE is 12.78 units

x point is 6, and the translation is x - 6

6 - 6 = 0

x = 0

y point is 0 and translation is y - 1

0 - 1 = -1

y = -1

Coordinates are (0,-1)

Find the nth term of this number sequence<br>15, 12, 9, 6....​
Ann [662]

Answer:

You only have four terms so n can only be 1, 2, 3 or 4!

I think you mean: What is the nth term of the sequence 15, 12, 9, 6, …?

The ellipsis (…) tells us that the sequence continues.

This is an arithmetic sequence, where the general term is:  a+bn  

n=1:a+b=15  [Eq. 1]

n=2:a+2b=12  [Eq. 2]

Subtracting Eq. 1 from Eq.2:  b=−3  

Substituting this into Eq. 1:  a−3=15⇒a=18

Thus the nth term is:  18−3n

HELP,ME PLEASE IM RLLY CONFUSED ON THIS ONE,THANKS IN ADVANCED

We can notice that : Line Passes through the Points  (1 , 2) and (4 , -4)

Let us find the slope of the line in order to write the Equation of the Line.

Slope of a Line Passing through two points (x₁ , y₁) and (x₂ , y₂) is given by :

\heartsuit\;Slope(m) = \frac{y_1 - y_2}{x_1 - x_2}

Points are (1 , 2) and (4 , -4)

here x₁ = 1 and x₂ = 4 and y₁ = 2 and y₂ = -4

\heartsuit\;Slope(m) = \frac{2 + 4}{1 - 4} = \frac{6}{-3} = -2

Equation of the Line passing through (1 , 2) and having slope -2 is :

⇒ y - 2 = -2(x - 1)

⇒ y = -2x + 2 + 2

⇒ y = -2x + 4
