Determine whether each table represents a linear, quadratic, exponential function.

Nesterboy [21]

Answer:

A: Exponential

B: Quadratic

C: Linear

Step-by-step explanation:

Let analyse each table

Table A

X Y ΔY/ΔX

1 5 xxxxxx

2 11 11 - 5 = 6

3 29 29 - 11 = 18

4 83 83 - 29 = 54

.....................

We can see that, [ ΔY/ΔX ] increases at the fastest rate out of all functions, so it must be exponential function

Table B

X Y ΔY/ΔX Δ^2Y/ΔX^2

0 5 xxxxxx xxx

1 7 7 - 5 = 2 xxx

2 13 13 - 7 = 6 6-2 = 4

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

..............................

It is a quadratic because Δ^2Y/ΔX^2 = 4 and are constant for all values

Table C

X Y ΔY/ΔX

3 20 xxxxxx

6 18 2 / 3

9 16 2 / 3

15 12 2 / 3

..............

It is a linear because ΔY/ΔX = 2/3 are constant for all values

7. A man makes a simple discount note for $6,200, at an ordinary bank discount rate of 8.84%, for 40 days. What is the effective

Elina [12.6K]

Answer:

The effective interest rate, rounded to the nearest tenth, is 0.1%.

Step-by-step explanation:

The banker's rule is the simple interest formula.

The simple interest formula is given by:

$E = P*I*t$

In which E are the earnings, P is the principal(the initial amount of money), I is the interest rate(yearly) and t is the time, in years.

The effective interest rate is given by the following formula:

$E_{IR} = \frac{E}{P}$ .

In this problem, we have that:

A man makes a simple discount note for $6,200, at an ordinary bank discount rate of 8.84%, for 40 days. We consider that the year has 360 days. This means that $P = 6200, I = 0.0884, t = \frac{40}{360} = \frac{1}{9}$ .

$E = 6200*0.0884*\frac{1}{9} = 60.9$

The effective interest rate is

$E_{IR} = \frac{E}{P} = \frac{60.9}{6200} = 0.0098 = 0.001$

The effective interest rate, rounded to the nearest tenth, is 0.1%.
