Answer:

<h2>b. -3</h2>

Step-by-step explanation:

The common difference in an arithmetic sequence:

d=a_{n+1}-a_n

27 - 30 = -3

24 - 27 = -3

21 - 24 = -3

18 - 21 = -3

CORRECT :)

It's constant.

Answer:it is -2

Step-by-step explanation:

First you need to put it into y=mx+b

Then it would be -5y=-3x+10

Divide all numbers by -5 so it would look like this

y=3/5x-2

Answer:

  D.  right 4, down 8

Step-by-step explanation:

The usual transformations applied to functions are ...

  f(x) ⇒ f(x -h) . . . . translation right h units

  f(x) ⇒ f(x) +k . . . . translation up k units

  f(x) ⇒ k·f(x) . . . . . vertical scaling by a factor of k; reflection over x-axis when k < 0

  f(x) ⇒ f(x/k) . . . . . horizontal scaling by a factor of k; reflection over y-axis when k < 0

In the above, "scaling" will be expansion when |k| > 1, compression when |k| < 1.

__

Your transformation is ...

  x^2 ⇒ (x -4)^2 -8

  f(x) ⇒ f(x -4) -8

This is translation with h=4 and k=-8. That is, it is translation right 4 units and down 8 units.

Like much of math, it is all about matching patterns.

a memory is a memory from a real event that was encoded, stored, but not retrieved for a long period of time; it is retrieved af
Inga [223]

Implicit or Doubtful memory of actual events that was stored encrypted, but was not retrieved for a long time until subsequent events suddenly brought it back to consciousness. The establishing, stabilizing like processes include in this memory.

Implicit Memory is a type of long-term memory and it is also known as unconscious memory or automatic memory. Implicit memory draws on past experiences to remember things without thinking. The power of tacit memory is made possible by past experiences, regardless of how long ago those experiences were.

Second stage of long-term memory formation.

Implicit memory, a subset of procedural memory, allows you to perform many everyday physical activities, such as walking and cycling, without having to think about it. Most of the implicit storage is procedural in nature.

For example:

  • typing on a keyboard
  • brushing your teeth. Riding a bicycle
  • Most people find it easy to ride a bike, even after years of not riding.
