I believe the phi ratio^2 = 1 + phi ratio
phi ratio = 1.6180339
phi ratio^2 = 2.6180339
ANSWER
1. k=13
2. x=-10
EXPLANATION
The given function is
To find f(x+5), plug in (x+5) wherever you see x.
This implies that:
Expand:
Simplify to obtain
We now compare with,
This implies that:
To find the smallest zero of f(x+5), we equate the function to zero and solve for x.
The smallest zero is -10.
Umm sorry i do not know that answer I am just getting the points for again so so so sorry ;(
Answer:
V = 4*8
V= 32
(x+x) * (x+x) = 2x * 2x = 4x^2
Answer:
AB=AC, BD is shared side, angle 1 and angle 2 are equal as BD bisects angle ABC
So we have two sides and included angle equal.
- <em>If two sides and the included angle of one triangle are equal to the corresponding sides and angle of another triangle, the triangles are congruent.</em>
According to the rule above we can say triangles ΔABD ≅ ΔCBD
