Satish is making school spirit keychains, which consist of a sequence of n beads on a string. he has blue beads and gold beads. how many unique keychains can he make with exactly k ≤ n blue beads?

Step-by-step explanation:

Satish is making school spirit key chains, which consist of a sequence of n beads, that are blue and golden.

Also given, there are k ≤ n blue beads.

So, the number of unique key chains that can be made is :

;

d.) yes, because the volume of the cone is greater than the volume of the sphere

step-by-step explanation:

the domain of a function is the set of input values, x , for which a function is defined. the domain is shown in the left oval in the picture below. the function provides an output value, f(x) , for each member of the domain.
