Determine weather each table represents a linear, quadratic, or exponential function.
solong [7]

Answer:

A: Exponential

B: Quadratic

C: Linear

Step-by-step explanation:

Solution:-

- We will closely inspect each Table and find the difference between each "Y" value at every unit increase in "x" value:

Table A:

 X            Y              ΔY/ΔX

 1             5               xxxxxx              Exponential because [ ΔY/ΔX ]          

 2            11              11 - 5 = 6            increases at the fastest rate out of all

 3           29             29 - 11 = 18         functions.

 4           83             83 - 29 = 54

 5           245          254 - 83 = 171

 6           731           731 - 254 = 477

Table B:

 X            Y                 ΔY/ΔX            Δ^2Y/ΔX^2          

 0             5                 xxxxxx              xxx             Quadratic because

 1              7                 7 - 5 = 2            xxx            Δ^2Y/ΔX^2 is a constant

 2             13               13 - 7 = 6           6-2 = 4       for all quadratic functions

 3             23              23 - 13 = 10       10-6 = 4

 4             37              37 - 23 = 14       14-10 = 4

 5             55             55 - 37 = 18        18-14 = 4

Table C:

 X            Y                 ΔY/ΔX                      

 3             20               xxxxxx                 Linear because

 6             18                 2 / 3                    ΔY/ΔX is a constant

 9             16                 2 / 3                   for all linear functions

 15            12                 2 / 3      

 27            4                  8/12 = 2/3      

 39           -4                  8/12 = 2/3

Angharad had an operation costing $500 She was in hospital for x days The cost of nursing care was $170 for each day she was in
Ket [755]

Answer:

a) Total cost = 500 + 170x

b) 11 days

Step-by-step explanation:

Given:

(a)

Number of days in hospital = x

Cost of operation = $ 500

Cost of nursing per day = $170

∴ Cost of nursing for x days = $ 170x

Therefore, the expression for total cost of her operation and nursing care is given as,

C=500+170x, where C is the total cost.

(b)

Given:

Total cost of operation = C=\$ 2370

Using the expression obtained in (a), we solve for x.

C=500+170x

Plug in 2370 for C and solve for x. This gives,

2370=500+170x\\ 170x=2370-500\\ x=\frac{1870}{170}\\x=11

Therefore, Angharad stayed in hospital for 11 days.

Step-by-step explanation:

Divide both sides by 1 to get rid of the 1

x - 2 = -5.5

Add 2 on both sides

x = -3.5
