F(n) = -11 + 22(n = 1) Complete the recursive formula of f(n). f(1) = f(n) = f(n - 1)+

Maslowich

Answer:

$f(n)=f(n-1)+22$ .

Step-by-step explanation:

Note: In the given function it should be (n-1) instead of (n=1).

Consider the given function is

$f(n)=-11+22(n-1)$

It is the explicit form of an A.P.

For $n=1$ ,

$f(1)=-11+22(1-1)=-11+0=-11$

For $n=2$ ,

$f(2)=-11+22(2-1)=-11+22=11$

Common difference is

$d=a_2-a_1=11-(-11)=11+11=22$

The recursive formula of an A.P. is

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

Substitute $d=22$ in the above formula.

$f(n)=f(n-1)+(22)$

$f(n)=f(n-1)+22$

Therefore, required recursive formula is $f(n)=f(n-1)+22$ .

A new parking lot is being built for a medical office. The expression representing the number of parking spots in the new lot is

docker41 [41]

Answer:

111 spots

Step-by-step explanation:

Let y denote the total number of parking spots expressed as:

$y=\frac{15x}{4}-9\\\\$

Given that x is the number of spots in the first row.

-Now, given that the first row has 32 spots, we substitute in the expression to solve for y:

$y=\frac{15x}{4}-9,\ \ x=32\\\\=\frac{15\times 32}{4}-9\\\\=120-9\\\\=111$

Hence, there are 111 spots in the parking lot.
