A bag contains tiles with letters on them spelling the word BANANA. A tile is removed, taken note of, then replaced. Another tile is then drawn. Find the probability that a) the first time was a B and the second tile was an N. b) the first time was an N and the second tile was an A.

720

Step-by-step explanation:

This is a permutation, since order is important (in other words, banana is not the same as bnanaa).

Since there are 6 letters, we find this using 6! (factorial):

6(5)(4)(3)(2)(1) = 720

the solution is the point

step-by-step explanation:

we have

> equation a

> equation b

adds equation a and equation b

substitute the value of x in equation b to find the value of y

the solution is the point

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1
