A bag contains ten marbles of the same size: 3 are identical green marbles, 2 are identical red marbles, and the other 5 are fiv

denpristay [2]

Answer:

total number of distinct combination is 82

Step-by-step explanation:

Given data:

green marbles 3

red marbles = 2

number of distinct colors is 5

different cases of combination of 5 marbles is

case -1 when there is 5 distinct color marble - $^7C_5 = 21$

case - 2 when there is 3 different color and two are of same color $^6C3_ \times 2 = 30$

case 3 - when 2 are of different type and 3 are of same color $= ^6C2_ = 15$

case 4 - when 1 are of different color and 2 are of different color $=^5C1_ \times \frac{4!}{2! 2!} = 15$

case 5 when three are of same type and 2 are of different color = 1

total number of distinct combination is 82

In a unit circle, what is the length of an arc that subtends an angle of <br> π/4 radians?

olchik [2.2K]

A unit circle has radius 1, and thus circumference $2\pi$ .

Since an angle of $\frac{\pi}{4}$ is one eighth of a whole turn, the length of an arc that subtends an angle of $\frac{\pi}{4}$ radians will be one eighth of the whole circumference:

$l = \dfrac{2\pi}{8} = \frac{\pi}{4}$

In fact, the radians have the property that, in the unit circle, the length of the arc is exactly the measure of the angle. In general, you have

$l = r\cdot\alpha$

where l is the length of the arc, r is the radius and $\alpha$ is the angle in radians. So, if $r=1$ , you have $l=\alpha$
