A) Write a as the subject of the formula s=n/2(a+l)? please help .​

AP(Arithmetic progression).

Step-by-step explanation:

Given formula;

s=n/2(a+l)

Explanation;

Given formula;

s=n/2(a+l)

Explanation;

The given formula is used to calculate the sum of the given AP(Arithmetic progression).

In which;

S = Sum of AP(Arithmetic progression).

n = number of terms in AP(Arithmetic progression).

a = first term of AP(Arithmetic progression).

l = last term of AP(Arithmetic progression).

step-by-step explanation:

once you graph it hit 2nd (the blue button) and graph

that takes you to a table of coordinates

on the left is x coordinates and on the right is y coordinates and an empty box

(you may have to scroll up/down in order to get ( x, 0)

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1
