Answer:

2nd option

Step-by-step explanation:

the recursive rule is

$a_{n}$ = $a_{n-1}$ + d ( d is the common difference )

use the explicit rule to find a₁ and d

a₁ = 48 - 11(1) = 48 - 11 = 37

a₂ = 48 - 11(2) = 48 - 22 = 26

then

d = a₂ - a₁ = 26 - 37 = - 11

recursive rule is then

$a_{n}$ = $a_{n-1}$ - 11

a₁ = 37

If f(x) = 8^x , find the value of f(2/3).

Licemer1 [7]

Answer:

Step-by-step explanation:

This is a substitution question

So we will have to substitute the value of x given into the given question

f(x)=8^x

And x is given as 2/3

So let's get to work

8^2/3 which means that cube root of 8 then square the answer

(3√8)^2

Cube root of 8 is 2

So we will have to square 2 to get 4

Therefore the final answer is 4

Answer:

The 6 Lego kits can be selected from the 9 available Lego kits in 84 ways.

Step-by-step explanation:

Use combinations to solve this problem.

Combination is defined as the selection of <em>r</em> elements from <em>n</em> distinct objects irrespective of the order. The objects cannot be replaced.

There are 9 Lego kits available.

And the total number of children is 6.

That is, we need to select 6 Lego kits from the 9 available Lego kits.

6 Lego kits can be selected from the 9 available Lego kits in $9\choose 6$ ways.

Solving the combination as follows:

${9\choose 6}=\frac{9!}{6!\times(9-6)!} \\=\frac{362880}{720\times6}\\ =84$

Thus, there are 84 ways to select 6 Lego kits from 9 available Lego kits.
