Serial numbers for a product are to be made using 2 letters followed by 2 digits. The letters are to be taken from the first 6 l
Andru [333]
Alright so I'm coming up with this on the fly; you have the first six letters (a,b,c,d,e,f) and 0-9 and your ten numbers. calculate the amount of possible combinations for the letters by simply writing them down.
ab, ac, ad, ae, a f- five
bc, bd , be, bf- four
cd, ce, cf- three
de, df- two
ef,- one.
adding these all together gets a total of 15 for the letters. now the numbers
01, 02, 03, 04, 05, 06, 07, 08, 09- nine
12, 13, 14, 15, 16, 17, 18, 19- eight
23, 24, 25, 26, 27, 28, 29- seven
34, 35, 36, 37, 38, 39- six
45, 46, 47, 48, 49- five
56, 57, 58, 59- four
67, 68, 69- three
78, 79- two
89- one
added together with a total of 45 combinations.
alright so, 45 different number combinations and 15 letter combinations. multiplying 15 by 45 should tell you the total possible combinations for a two letter and two number serial-number

Can someone help me plzz
Rashid [163]
Let's go through each answer choice and eliminate the choices.

a) 6(2/3) = 4, this is less than 6, making it our correct answer, but still go and check each answer
b) 6(2/3) again = 4, this is less than 6, making this answer choice wrong.
c) 6(3/2) = 9, this is greater than 6, making this answer choice wrong.
d) 6(3/3) = 6, this is equal to 6, making this answer choice wrong.

What is the equation of the axis of symmetry for the parabola y= 1/4(x+2)^2-7
Nezavi [6.7K]
Your answer is -2 as the axis of symmetry is at -b/2a. So if you were to expand the equation, you would get y= x^2/4 +x -6 where b is 1 and 2a is ½ . Therefore -1 / ½ gives you -2
