Prove: The square of a number that is

Mathematics
1 answer:
Nikolay [14]2 years ago
3 0

Let 3<em>n</em> + 1 denote the "number" in question. The claim is that

(3<em>n</em> + 1)² = 3<em>m</em> + 1

for some integer <em>m</em>.

Now,

(3<em>n</em> + 1)² = (3<em>n</em>)² + 2 (3<em>n</em>) + 1²

… = 9<em>n</em>² + 6<em>n</em> + 1

… = 3<em>n</em> (3<em>n</em> + 2) + 1

… = 3<em>m</em> + 1

where we take <em>m</em> = <em>n</em> (3<em>n</em> + 2).

HELP ASAP PLEASE!!! This is a written response
o-na [289]

Answer:

Exponential decay.

Step-by-step explanation:

The magnitude of the base (also known as the "common factor") tells us whether a given exponential equation represents growth or decay.

Standard equation for expo. growth:  y = 3(b)^x, where b is the base.

If 0<b<1, we have expo. decay; if 1<b, we have expo. growth.

Thus, y = 3(0.5)^x represents expo. decay.
