The # of meals decreased by a total of 120 - 52 = 68 meals. Now in order to find the percent decrease, you must find what total percent 68 is out of 120.

68/120 = x/100, this ratio will give you the percent that 68 is out of 120 if you solve for x.

Using inverse operations you get:

6800 = 120x

x = 56.7% when rounded. Meaning that the total percent decrease was about 56.7

Find the explicit formula for a 1 =-4,a n =a n-1 +9,n>=2

Mrrafil [7]

Given:

$a_1=-4$ and $a_n=a_{n-1}+9$ where $n\geq 2$ .

To find:

The explicit formula for the given recursive formula.

Solution:

We know that recursive formula of an AP is:

$a_n=a_{n-1}+d$

Where, d is the common difference.

We have,

$a_n=a_{n-1}+9$

Here, d=9.

The first term of the AP is $a_1=-4$ .

The explicit formula for an AP is:

$a_n=a_1+(n-1)d$

Substituting $a_1=-4$ and $d=9$ , we get

$a_n=-4+(n-1)9$

$a_n=-4+9n-9$

$a_n=-13+9n$

Therefore, the required explicit formula for the given sequence is $a_n=-13+9n$ .

Answer: D. (-4, -2)

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

Rotating 180° about the origin means the signs for the x- and y-values are opposite.

(x, y) → (-x, -y)

(4, 2) → (-4, -2)
