R(p) = -15p² + 200p + 10,000
To find the maximum of the function, we take the first derivative and equate to 0:
R'(p) = -30p + 200
0 = -30p + 200
p = 6.67
A price of $6.67 will maximize revenue.
Y = 3x + 4
y = -x - 4
3x + 4 = -x - 4
3x + x = -4 - 4
4x = -8
x = -8/4
x = -2
y = 3x + 4
y = 3(-2) + 4
y = -6 + 4
y = -2
solution is (-2,-2) <==
Step-by-step explanation:
Z=97°
(D&B are across from each other)
Y=43°
(alternating angles)
X=40°
(inside corners of a triangle) (it is always 180°)
=97°+43°+40°
=180°

{5, 2, 23} is a subset of {5, 2, 23}, so {5, 2, 23} is the smallest set
