Answer:

1) Yes, 1/2 and 2

2) b=1/2 × t

t=2 × b

Step-by-step explanation:

1) Yes, because every package of a toy equals 2 batteries. The constant of proportionality is 1/2 and 2 because 1 ÷ 2 = 1/2 and 2 ÷ 1 = 2 (amount of toys divided by amount of batteries and vice versa)

2) b = 1/2t, because for every battery, there is 1/2 a toy.

t = 2b, because for every toy, there are 2 batteries

note: you can't actually have 1/2 a toy, but we write it like that for the sake of showing the relationship of toy to battery.

Write an explicit formula for an,the Nth term of the sequence 4,12,36

Rudik [331]

Answer:

$3^{n}+3^{n-1}$

Step-by-step explanation:

Since the sequence is geometric (it multiplies the previous number each time). The nth term sequence would be $x^n + yn$

Because the sequence multiplies by 3 each time, The base number in that equation would be $3^n +yn$ .

So $3^n$ of the equation would be:
$3, 9, 27$ .

Compare the 2 equations:
4, 12, 36

3, 9 ,27

The difference between the 2 equations is: 1, 3, 9 which itself is a geometric sequence so the nth term of this new equation is: $3^{n-1}$ .

Combine these 2 equations together and you get:

$3^{n}+3^{n-1}$ .

the function F(x) represents the monthly earnings of sales executive, which consists of a base salary and a comission earned on

Rasek [7]

Since, the function F(x) represents the monthly earnings of sales executive, which consists of a base salary and a commission earned on each scale, where 'x' is the number of sales.

So, the function F(x) can be expressed as:

F(x)= base salary+ commission earned on each sale (x) where 'x' represents the number of sales done.

So, F(0)= base salary + 0 ( As x=0 implies there was no sale)

And the executive earned only his base salary and no commission as he did not make any sale, and the commission was dependent upon the number of sales (x).

Hence, F(0) represents the base salary.

So, Option J is the correct answer.
