3²
Step-by-step explanation:
3×3=3² -> an exponent
Answer:
Step-by-step explanation:
"length is 4 meters less than 2 times the width"
L = 2W+4
"perimeter is 40 meters"
2L+2W = 40
L+W = 20
(2W+4) + W = 20
3W + 4 = 20
W = 16/3 meters
Is this for calculus for for algebra?
I'm going to assume that you know calculus.
df
---- = 2ax + b must equal zero if (-1,2) is an extreme value of f(x).
dx
Thus, 2ax + b = 0, and 2ax = -b, or x = -b/(2a). This is the familiar "x-coordinate of the vertex of a parabola."
Here that x-value is -1, so -1 = -b/(2a). From this we get -2a = -b, or
b=2a
so the ordered pair could be (a, 2a).
