Answer:

18564

Step-by-step explanation:

In the problem Given, we just need to see t any 6, the order of selection does not matter, hence, this is a combination problem :

Using the combination relation :

nCr = 18C6

Recall ;

nCr = n! / (n-r)!r!

18C6 = 18! / (18-6)!6!

18C6 = 18! / 12!6! = (18*17*16*15*14*13) / (6*5*4*3*2*1)

18C6 = 13366080 / 6!

18C6 = 18564

Bobby bought 3 5/12 ft of red ribbon and 5 1/12 ft of yellow ribbon. ribbon costs $1.20 a foot. How much did Bobby spend on ribb

puteri [66]

First multiply the big numbers. 3*1.20= ($3.60) and 5*1.20= ($6)
Now the fractions, 1/12 would equal 10 cents. 5/12 + 1/12= 6/12 which would also equal (60 cents). 3.60+6.00+.60= $10.20

The diameter of a circle has length 12. The center is at*(-5, 2). Give the equation

labwork [276]

Answer:

Equation of the circle is : $x^{2} + 10x + y^{2} -4y -7 =0$

Step-by-step explanation:

Let us consider the image attached in the answer area.

The center O has the co-ordinates i.e. (-5,2) and the diameter given is 12 units.

We know that radius is half of diameter.

$\text{Radius = }\dfrac{\text{Diameter}}{2}$

$\text{Radius = }\dfrac{12}{2}\\\Rightarrow \text{Radius = 6units}$

The equation for circle given the center and radius, can be represented as:

$(x-a)^{2}+ (y-b)^{2} = r^{2}$

Where (a,b) is the co-ordinate of center and r is the radius.

Let us consider the following formula:

$(p+q)^2 = p^{2}+ q^{2} +2pq\\(p-q)^2 = p^{2}+ q^{2} -2pq$

$(x-(-5))^{2}+ (y-2)^{2} = 6^{2}\\\Rightarrow (x+5)^{2}+ (y-2)^{2} = 36\\\Rightarrow x^{2} + 25 + 10x +y^{2} + 4-4y=36\\\Rightarrow x^{2} + 10x +y^{2} -4y-7=0$

Hence, Equation of the circle is : $x^{2} + 10x + y^{2} -4y -7 =0$
