4x4x4=64. Hope that helps
3 can be anything greater than (but not equal to) 90 and 1 can be anything less than (but not equal to) 90 as long as angle 3 + angle 1 = 180 degrees.
Answer:
1) choice B, they are equal in length
2) choice A, theyre equal in length
3) Choice D, (-3,0) (-3, -3) (-1, -3)
4) Choice A, Clockwise 90- degree rotation

Answer:
(b) 30
Step-by-step explanation:
The standard form of a quadratic is ...
y = ax^2 +bx +c
For such a function, the axis of symmetry is ...
x = -b/(2a)
Your quadratic function has a=-5, b=+300, so the axis of symmetry is ...
x = -300/(2(-5) = 30
The peak of the curve is on the axis of symmetry. So, profit is maximized when 30 items are produced.
_____
Of course, a graphing calculator can display the maximum of the function easily.
