You want to create an ID code for the students in your school based on three characters. The first and second characters must be

a letter of the alphabet, and the third must be a digit between 1 and 9 inclusive. To find out how many different codes there are, would a list or tree diagram be practical in this case? Why or why not?

A list would work so much better cause u can list all the possibilities and the diagram would be no help in this case because a diagram is only going to show u certain parts when u can get all answers from a list.

<h2>Answer with explanation:</h2>

As we know that there are 26 letters in a alphabet and we are asked to use 9 digits in the third place.

So, the total number of such cases possible are or the total number of codes than can be created using a letter in the first two place and a digit in the third place are:

     26×26×9=6084

( Since in the first place there are a choice of  26 letters and for the second place again we have a choice of 26 letters as it is not mentioned that the repetition is not allowed and for the third place we have 9 choices)

  • Hence, to represent these 6084 cases via tree diagram is too complex and difficult as it will have too many branches.
  • Also, the listing of these cases could be done by computer but manually listing these cases is too tiring and time taking.

Which of the following is equivalent to 2x+3y=6
valentina_108 [34]

Answer:

A. y = -2/3x + 2

Step-by-step explanation:

Your is to isolate the y. The first thing you would do is subtract the 2x,

2x + 3y = 6

-2x        =

3y = -2x +6

then to isolate the ,y, you would next divide everything by 3, so that the ,y, stays by itself.

3y/3 = -2x/3 +6/3

Simplify,

y = -2/3x + 2

Daredevil Danny takes a practice jump as shown on the graph below. Complete the steps to determine the equation for the paraboli
solniwko [45]

Answer:

Step 4

part a: no answer yet still having trouble showing my work

part b:

-0.125(x-24)^2+50

-0.125(x-24)(x-24)+50

-0.125(x^2-24x-24x+576)+50

-0.125(x^2-48x+576)+50

-0.125x^2+6x-75+50

-0.125x^2+6x-22

a=-0.125

b=6

c=-22

part c: yes he went through

part d:

plug in roots (4,0) and (44,0)

if x is 4 and y is 0

0=-0.125(4)^2+6(4)-22

0=-2+24-22

0=-2+2

0=0

if x=44 and y=0

0=-0.125(44)^2+6(44)-22

0=-242+264-22

0=-242+242

0=0
