Answer:
Given below
Step-by-step explanation:
The algebraic identity is (a-b)^2
= a^2 + b^2 - 2ab
So it'll be,
(x-4)^2
= x^2 + (4)^2 - (2)(x)(4)
= x^2 -8x + 16
or x^2 +16 -8x
Answer: the first one is 30. The second is .294. The third is 2/3.
Step-by-step explanation:
Focus of a parabola:
where vertex (h,k) p is the distance from vertex to focus
Vcylinder = πr2h
After plugging everything in you should get (3.14)(3.9)(30) this simplifies should get you 367.38m^3. Hope this helps!
