Use an induction proof to prove this statement:<br> For n≥1, 4^n+5 is divisible by 3.
Tpy6a [65]

Answer:

See below

Step-by-step explanation:

We shall prove that for all n\in\mathbb{N},3|(4^n+5). This tells us that 3 divides 4^n+5 with a remainder of zero.

If we let n=1, then we have 4^{1}+5=9, and evidently, 9|3.

Assume that 4^n+5 is divisible by 3 for n=k, k\in\mathbb{N}. Then, by this assumption, 3|(4^n+5)\Rightarrow4^k+5=3m,\: m\in\mathbb{Z}.

Now, let n=k+1. Then:

4^{k+1}+5=4^k\cdot4+5\\=4^k(3+1)+5\\=3\cdot4^k+4^k+5\\=3\cdot4^k+3m\\=3(4^k+m)

Since 3|(4^k+m), we may conclude, by the axiom of induction, that the property holds for all n\in\mathbb{N}.

Could u guys try this one out as well
Korolek [52]

Answer:

D) a reflection over the line x = 0 followed by a reflection over the line y = 0.

Step-by-step explanation:

In this problem, the original figure is in quadrant I (1) and the second image is in quadrant III (3).  In order for the figure to make this transition and be 'flipped' into the opposite direction of the original figure, a reflection would have to take place.  If triangle 'A' is reflected over the line y = x or y = -x, the orientation of the triangle would stay the same, meaning the point of the triangle would still face upward.  If you reflect over the line x = 0 and then again over the line x = 0 (as in C), your triangle would be in the same spot.  However, if you reflect triangle 'A' over x = 0, you would get a 'flipped image' into quadrant 4 and the orientation of the triangle would face downward.  Following this reflection by another reflection over the line y=0 would give you the mirror image in quadrant III (3).  So, D is the correct sequence of reflections.
