The unsorted stem-and-leaf diagram would look like this:

5 | 6, 3, 5, 0, 2

3 | 2, 7, 3, 3, 4

2 | 6, 9, 1, 1

1 | 7, 1, 1, 6, 8

4 | 4, 2, 4, 3, 4

Basically, you separate the given set of numbers by their whole number part (the digit before the decimal) and list the numbers' fractional part (digit after the decimal) in the order you see them.

The sorted diagram would then be

1 | 1, 1, 6, 7, 8

2 | 1, 1, 6, 9

3 | 2, 3, 3, 4, 7

4 | 2, 3, 4, 4, 4

5 | 0, 2, 3, 5, 6

4.
h(f(x)=h(2x-1)=
(2x-1)^2+1=
4x²-4x+1+1=
4x²-4x+2

5.
f(f(x))=2(2x-1)-1=4x-2-1=4x-3

6.
f o g (x)=f(g(x))
h o g (x)=h(g(x))=

Question 2 Two trains leave the station at the same time, one heading west and the other east. The westbound train travels at 95
lianna [129]

Answer:

it will take 1.4 hours for the two trains to be 294 miles apart

Step-by-step explanation:

Let t be the time taken for each train

The westbound train travels at 95 miles per hour.

Speed of westbound train = 95

time = t

Distance = speed * time = 95 t

The eastbound train travels at 115 miles per hour

Speed of eastbound train = 115

time = t

Distance = speed * time = 115 t

both trains are 294 miles apart means the distance between both trains are 294 miles

So we add the distance of both trains and set it equal to 294

95t + 115t = 294

210 t =294

t = 1.4

So, it will take 1.4 hours for the two trains to be 294 miles apart
