Each sides are equal so the answer 400 cubic in

there are no inflection points, because it never changes concavity, is just a constant and thus for any region over the x-axis, will always be a positive value, and thus is always "concave up".
Answer:
16 degrees
Step-by-step explanation:
74 + 90 = 164

Answer:
#4= 1
#5= A=9,216
B=360
Step-by-step explanation:
number five x equals 9 and y = 1,024 so it's asking us that if x = 81 what would y = and to get 81 you need to multiply 9 by 9 so all you have to do is multiply 1024 by 9 to get 9,216 so y = 9,216 and the same thing goes for B
