Answer:

The length of the arc:

A = \frac{8}{5} \pi

Step-by-step explanation:

To find the length of the arc< you need this equation:

Arclength = \frac{a}{360\textdegree} 2\pi r

-Use the given radius 6 and the central angle 48\textdegree for the equation:

A = \frac{48\textdegree}{360\textdegree} 2\pi (6)

Then, solve the equation:

A = \frac{48\textdegree}{360\textdegree} 2\pi (6)

A = \frac{2}{15} \times 2\pi \times 6

A = \frac{4}{15} \pi \times 6

A = \frac{24}{15} \pi

A = \frac{8}{5} \pi

So, the length of the arc is \frac{8}{5} \pi .

Answer:

a)  A n  (B' n C') =  {3, 9}.

b) (AUB) n (BUC) = {2,4,5,6,7,8}

Step-by-step explanation:

a)  Rewriting C ; C = {4,5,6,7,8}

B' = {3,5,7,9} and C' = {2, 3, 9}

so (B' n C') = {3, 9}

and A n  (B' n C') =  {3, 9}.

b)  {A U B} = { 2,3,4,5,6,7,8,9} and {B U C} = {2,4,5,6,7,8}

so (AUB) n (BUC) = {2,4,5,6,7,8}

How do you find velocity of a dt graph
givi [52]
Answer: to find velocity, simply put (d2-d1) over (t2-t1) or d/t.

Explanation: To find velocity, divide the change in distance by the change in time. On a graph, pick two points and find the slope of one portion of the line.
Why the slope?
Well this is like your normal x vs. y graph. X being the time and y being your distance.
To find the slope for this, it uses the same formula: (Y2-y1) / (x2-x1)

Hope this helps!!!
BTW, this is physics.
