Find the number C(10,6)

EastWind [94]

Answer:

210.

Step-by-step explanation:

Combination formula is

$nCr = \frac{n!}{r!(n-r)!}$

Then, we have that n = 10 and r=6:

$C(10,6) = \frac{10!}{6!(10-6)!}$

$C(10,6) = \frac{10!}{6!4!}$

To simplify calculus, we are going to use that n! = (n-1)!n = (n-2)!(n-1)n and so on.

$C(10,6) = \frac{6!*7*8*9*10}{6!4!}$

$C(10,6) = \frac{7*8*9*10}{4!}$

$C(10,6) = \frac{5040}{4*3*2*1}$

$C(10,6) = \frac{5040}{24}$

$C(10,6) = 210.$

Question 2 Multiple Choice Worth 1 points)

likoan [24]

Answer:

Solution: means we replace 'x' with 'x+1' and we get g (x). Let us put x = 0 and then y = 0 to find two points on coordinate axis to easily plot the graph of g (x). Now, let us put y = 0 and find out x. So, second point is . Now, let us plot A and B then extend the line joining AB.

Does anyone know the answer? (It's not 0,4)

Murljashka [212]

I believe it would be any number that is within the darkest shaded area. (-4,1) seems like it would be correct.

angle and angle b are complentary angles. if angle a = (2x-5) and m angle b = (5x+4) then find the measure of angle a

iris [78.8K]

complementary angles = 90

2x-5 + 5x+4 = 90

combine like terms

7x-1 =90

7x = 91

divide by 7

x =13

angle a

2x-5

2*13-5

26-5

Angle a: 21

Julia is going for a walk through the neighborhood. What unit of measure is most appropriate to describe the distance she walks?

Kryger [21]

Answer:

Possibly meters or feet/yards.

A walk through a neighborhood would be less than a mile/kilometer but much further than an inch/centimeter.
