A) kilometers, B) cubic meters
Answer:
f''(2) = 8
Step-by-step explanation:
f'(x)= 2x³ - 4x +3
f''(x)= 2*3x - 4= 6x - 4
f''(2)= 6*2 - 4 = 12 - 4 = 8
Answer:
A=lw+l(w
2)2+h2+w(l
2)2+h2
Step-by-step explanation:
In geometry, the definition of a triangle is a two-dimensional closed figure with three sides. Aside from this, it is proven that the sum of the angles of a triangle is 180°. This is a triangle's innate property. Therefore, any closed shape with three sides is a triangle and it follows that the sum of the three angles is equal to 180°.
It is logical therefore, that the first step in proving this is by using the definition of a triangle.
