Arc length = θ/2pi * 2pi * r = θ * r = 2pi/7 * 3 = 6pi/7 = 2.69 cm

Answer:

Length of the arc will be 2.69 cm.

Step-by-step explanation:

We have to calculate the length of an arc if θ = $\frac{2\pi }{7}$ and radius of arc is 3 cm.

As we know length of an arc = r × θ

By putting the values of angle θ and radius of arc r in the formula

m (arc) = $\frac{2\pi }{7}$ × 3

= $\frac{6\pi }{7}$

= $\frac{6(3.14)}{7}$

= 2.69 cm

Therefore, length of the arc will be 2.69 cm.

Parallel Lines Cut by a Transversal: Maze

CaHeK987 [17]

Start from Start Here square, the pointer to the next question to resolve is given by the solution to the equation in the current square

The values of the Maze are as follows;

x = 10
x = 8
x = -9
x = 5
x = 11
x = 3
x = -5
x = 9
x = 7
x = -7

Reason:

The solutions are;

10·x + 15 = 12·x - 5 by alternate interior angles theorem

∴ x = 10

6·x + 6 = 5·x + 14 by alternate exterior angles theorem

∴ x = 8

x + 109 = 100 by corresponding angles theorem

∴ x = -9

11·x + 5 + 120° = 180° by same side interior angles theorem

∴ x = 5

11·x - 1 = 10·x + 10 by corresponding angles theorem

∴ x = 11

35·x + 5 = 110 by corresponding angles theorem

∴ x = 3

x + 85 + x + 105 = 180 by same side interior angles theorem

∴ x = -5

7·x - 3 + 12·x + 12 = 180° by same side interior angles theorem

∴ x = 9

19·x - 3 = 130 by alternate interior angles theorem

∴ x = 7

x + 67 = 60 by alternate interior angles theorem

x = -7

Find the solution of 2/3x+1/4=-4/3

wolverine [178]

These questions can be daunting at first, but they're pretty simple to solve.

First, we need to establish a common denominator. We have 2 / 3, 1 / 4, and
-4 / 3. The least common denominator we can get is by multiplying 4 and 3 together to get 12. So we will change the denominator as follows;

2 / 3, 1 / 4, -4 / 3 = 8 / 12, 3 / 12, -16 / 12

Now we can put these back into the equation.

8/12x + 3/12 = -16/12
8x + 3 = -16

It's simple math from here on out, but I'll show the process. What we can basically do now is take away the denominator because it doesn't matter now that it's common.

Subtract 3 from both sides. Now we have 8x = -19

Dividing by 8 on both sides of the equation will get you your answer.

x = -19/8

Hope this helps!

How do I solve this problem? The green dots can be moved

olganol [36]

Answer :

Points at (1, 3) and (3, 3) and (2, 1)

Explanation:

The original graph (dashed) is an absolute value function meaning f(x) = |x|

Given: y = 2f(x - 2) + 1

f(x - 2) means you plug in x - 2 for x in f(x) function

the new graph equation is: y = 2|x - 2| + 1

The graph will shift up 1 because +1
The graph will shift right because -2
The graph has a scale factor of 2
The graph is V shaped because it is an absolute value graph
