$11.60 (see below)

Step-by-step explanation:

First, you need to find the total cost of the two items bought:

Add the two decimals together:

      1    1

  $ 4 . 9 7

+ $ 3 . 4 3

  $ 8  . 4 0

So the total cost was $8.40.

If this was paid by $20, then you will have to subtract the cost:

     1  9  10  

  $ 2 0 . 0 0

– $    8 . 4 0

  $ 1  1 . 6 0

So the change was $11.60.

The pattern is adding 1.43 to the term before

1.11 + 1.43 = 2.54 + 1.43 = 3.97 + 1.43 = 5.40 . . .and so on.

1.   Vertex is (-12, -101)

2.   Vertex is (4, 25)

Step-by-step explanation:

1)

y =  x^{2}  + 24x + 144 + 43 - 144\\   =  (x + 12)^{2}  - 101

Vertex is (-12, -101)

2)

y = -x^{2}  + 8x + 9\\    = -(x^{2}  - 8x + 16)  +9 + 16\\    =  -(x - 4)^{2}  + 25

Vertex is (4, 25)

It will take 4.71 hours to travel a distance of 221.43 miles

Step-by-step explanation:

Given

Distance covered in time 7.99 hours is  375.32 miles.

Now we know that speed is equal to distance per unit time.

Therefore,

speed = \frac{distance}{time} \\= \frac{375.32}{7.99}\\=46.97\ mi/h

Which is the constant speed, hence now time taken for a distance of 221.43 miles will be

time = \frac{distance}{speed} \\=\frac{221.43}{46.97} \\=4.71\ h

Therefore, the time taken to cover 221.43 miles is 4.71 hours.
