The recursive function LaTeX: f\left(0\right)=1,\:f\left(n\right)=f\left(n-1\right)+2nf ( 0 ) = 1 , f ( n ) = f ( n − 1 ) + 2 n

Question:

The recursive function $f(0) = 1$ , $f(n) = f(n-1) + 2n$ represents the nth term of a sequence. Determine the explicit function

Answer:

$f(n) = n^2 + n+1$

Step-by-step explanation:

Given

$f(0) = 1$

$f(n) = f(n-1) + 2n$

Required

Write an explicit formula

Let n = 1

$f(1) = f(1-1) + 2*1$

$f(1) = f(0) + 2$

$f(1) = 1 + 2 = 3$

Let n = 2

$f(2) = f(2-1) + 2*2$

$f(2) = f(1) + 4$

$f(2) = 3 + 4 = 7$

Let n =3

$f(3)=f(3-1) + 2 * 3$

$f(3)=f(2) + 6$

$f(3)=7+ 6 = 13$

Let n = 4

$f(4) = f(4 - 1) + 2 * 4$

$f(4) = f(3) + 8$

$f(4) = 13+ 8 = 21$

So, we have:

$f(1) = 3= 1 + 2 * 1=1+0*1*2*1$

$f(2) = 7= 3 + 2 * 2=1+1*2+2*2$

$f(3) = 13= 7 + 2 * 3= 1+2*3+2*3$

$f(4) = 21 = 13 + 2 * 4= 1+3*4 +2 *4$

Following the above pattern:

$f(n) = 1 + (n - 1) * n + 2 * n$

$f(n) = 1 + n(n - 1) + 2n$

Open bracket

$f(n) = 1 + n^2 - n + 2n$

$f(n) = 1 + n^2 + n$

$f(n) = n^2 + n+1$

May I please get help with this. For I am confused as I have tried multiple times to get the correct answers but still could not

ANSWER

$10.18$

EXPLANATION

We want to approximate, using the ALEKS calculator, the value of:

$\sqrt[]{103.7}$

To do this, we input the radical and the number into the calculator. The result is:

$10.18331969$

Since we have to round the answer to the nearest hundredth, we will pick the number in the thousandths place value, which is 3.

This number is less than 5, so, we round it down to 0 and add it to the number in the hundredth place value, which is 8.

Hence, the answer is:

$10.18$

What is the value of y in the equation 2(3y + 6 + 3) = 196 − 16?

mafiozo [28]

2(3y + 6 + 3) = 196 - 16

2 x (3y + 9) = 196 - 16

2 x (3y + 9) = 180

2 x 3y + 2 x 9 = 180

6y + 2 x 9 = 180

6y + 18 = 180

6y = 180 - 18

6y = 162

y = 162/6

y = 27
