So

  • f(n)=2.f(n-1)

Like that

f(2)

  • 2.3=3×2¹

f(3)

  • 2.2.3=3×2²

As you can see

It's an geometric progression

  • first term=a=3
  • common ratio =r=2

So the formula is

  • f(n)=3.2^{n-1}

None of the above

The sum of the digits of a two − digit number is 11. The unit's digit is 7 less than the ten's digit. Find the number.
padilas [110]

Answer:

Number = 92

Step-by-step explanation:

Let the unit digit is x and that of tens digit is y.

ATQ,

x+y = 11 ....(1)

The unit's digit is 7 less than the ten's digit

x = y-7 ...(2)

Put the value of x from equation (2) in (1)

y-7+y = 11

2x-7 = 11

2x = 11+7

2x = 18

x = 9

Put the value of x in equation (1)

9+y = 11

y = 2

Hence, the number is 92.

2. For the table, identify the independent and dependent variables, Represent the relationship using words, an equation and a gr
lys-0071 [83]
Here is your answer:

Independent Variable: Is a variable that is being tested..

Dependent Variable: Is a variable that's being measured.

So in this case.

The independent variable is water bottles in a case.

Dependent Variable: Is how many water bottles are in a case.

For this next part I'm not sure.

But as you look at the graph you see a pattern.

1×24=24

Etc...

So the equation will be: 1×24

The pattern is 24.

So....
1×24=24
2×24=48
5×24=120
10×24=240
20×24=480

Hope this Helps.
