We understand that a **combination** is a arsenal of the items wbelow the order doesn"t matter. It is a means to calculate the complete outcomes of an event wbelow order of the outcomes does not issue.

You are watching: Choose the correct definition of (n/k) from below** It is denoted by C(n,k) or (n,k) or (n/k)**.

**The formula for the variety of combicountries of n points taken r at a time is given by :-**

**Hence, C is the right choice.**

**steustatiushistory.org:**

the distance of the object prior to it hits the ground after launch is t = 1.592 seconds

**Step-by-action explanation:**

The height of an item released upward from ground level is offered by the attribute s(t) = -4.9t² +7.8t

as soon as the object reach the ground then s(t) = 0

So; -4.9t² +7.8t = 0

-4.9t² +7.8t + 0 = 0

By utilizing the quadratic equation

where; a = -4.9 ; b = 7.8 and also c = 0

Hence; the distance of the object before it hits the ground after launch is t = 1.592 seconds

**Step-by-step explanation:**

(02.02 MC) Triangle ABC is presented. A is at negative 2, 1. B is at negative 1, 4. C is at negative 4, 5. If triangle ABC is reflec

**Given:**

The vertices of a triangle ABC are A(-2,1), B(-1,4) and also C(-4,5).

Triangle ABC is reflected over the x‐axis, reflected over the y‐axis, and also rotated 180 degrees.

**To find:**

The suggest B".

**Solution:**

If a number reflected over x-axis, then

If a number reflected over y-axis, then

If a number rotated 180 levels around the beginning, then

So, the coordinate of point B" are (-1,4).
