What does "well defined" mean to you, in this situation?
What makes up this set is very clear: "1st graders," "Maple Elem. School," "male." No ambiguity here. How does this relate to the concept of "well defined set?"
Answer:
the correct ls D) = 12c^2-15
Step-by-step explanation:
Product means to multiply
3c (4c-5)
= (3c)(4c+5)
= (3c)(4c)+(3c)(-5)
= 12c^2-15
Oh and I got it correct on the USAPERtest

24
Step-by-step explanation
The question just ask to subtract 18 from 42 which would = 24.
Answer:
Step-by-step explanation:
Use SOH CAH TOA to recall how the trig functions fit on a triangle
SOH: Sin(Ф)= Opp / Hyp
CAH: Cos(Ф)= Adj / Hyp
TOA: Tan(Ф) = Opp / Adj
the side "?" is the Adjacent side (Adj) and we are given the angle and the Hypontenuse ( long side) (Hyp) of this triangle
so use CAH
cos(75) = Adj / 8
algebra to solve for the Adj side (which is the "?" for this problem )
8*cos(75) = Adj
2.07055 = Adj
so the "?" is 2.1 ft ( rounded to the nearest 10th )
