2(4)-3 is what f(4) is equal to if you imput 4 for x. Distribute 2 to the 4 to get 8-3 so f(4) is equal to 5!

PLZ I need help QUICKLY

dimulka [17.4K]

Answer:

The angles produced are not the same...

Step-by-step explanation:

I think the problem has an error in the answers. I get 33 for b and 31 for q which is NOT correct when they are both similar. In fact, even the question symbols aren't right. They're not congruent...they are similar so the symbol should be ~ not the concurrency. Sorry you have a stupid online system.

A playground is being designed where children can interact with their friends in certain combinations. If there is 1 child, ther

mariarad [96]

<h2>Answer:</h2>

Recursive equation for the pattern followed is given by,

$a_{n}=a_{n-1}+(n-1)^{2}$

<h2>Step-by-step explanation:</h2>

In the question,

The number of interaction for 1 child = 0

Number of interactions for 2 children = 1

Number of interactions for 3 children = 5

Number of interaction for 4 children = 14

So,

We need to find out the pattern for the recursive equation for the given conditions.

So,

We see that,

$a_{1}=0\\a_{2}=1\\a_{3}=5\\a_{4}=14\\$

Therefore, on checking, we observe that,

$a_{n}=a_{n-1}+(n-1)^{2}$

On checking the equation at the given values of 'n' of, 1, 2, 3 and 4.

At,

n = 1

$a_{n}=a_{n-1}+(n-1)^{2}\\a_{1}=a_{1-1}+(1-1)^{2}\\a_{1}=0+0=0\\a_{1}=0$

which is true.

At,

n = 2

$a_{n}=a_{n-1}+(n-1)^{2}\\a_{2}=a_{2-1}+(2-1)^{2}\\a_{2}=a_{1}+1\\a_{2}=1$

Which is also true.

At,

n = 3

$a_{n}=a_{n-1}+(n-1)^{2}\\a_{3}=a_{3-1}+(3-1)^{2}\\a_{3}=a_{2}+4\\a_{3}=5$

Which is true.

At,

n = 4

$a_{n}=a_{n-1}+(n-1)^{2}\\a_{4}=a_{4-1}+(4-1)^{2}\\a_{4}=a_{3}+9\\a_{4}=14$

This is also true at the given value of 'n'.

Therefore, the recursive equation for the pattern followed is given by,

$a_{n}=a_{n-1}+(n-1)^{2}$

Find the interest principle 8000 rate .06 compounded annually years 3

HACTEHA [7]

Answer:

535.07

Step-by-step explanation:

S=P(1+ i) ^n

i= nominal rate of interest / number of compounding periods

i =. 06/12

=0.18

Divided by 100

=0.0018

n- number of times interest is given per year x the number of years

n=12x3

=36

8000(1+0.0018)^36

=8535.07

Interest

8535.07 - 8000

=535.07
