Answer:

£707.8

Step-by-step explanation:

Given data

Price=  £800

Rate= 4%

Time= 3 years

Let us apply the compounding formula

A=P(1-r)^r-------------Note the negative sign is because of depreciation

substitute

A= 800(1-0.04)^3

A= 800(0.96)^3

A=800*0.884736

A=  £707.8

Hence the value will be £707.8

Answer:

  • 6 units left and 4 up (if figure K translated)
  • 6 units right and 4 units down (if figure J translated)

Step-by-step explanation:

<em>It is not clear which of the figures is translated.</em>

<em>Assume it is figure K.</em>

Use one of the points and compare the corresponding point.

<u>If you take bottom-left point, then the difference is coordinates is:</u>

  • -7 - (-1) = -6, this is translation left by 6 units (or right if the figure J is translated)
  • 2 - (-2) = 4, this is translation up by 4 units (or down if the figure J is translated)

<u>So the answer is </u>

  • 6 units left and 4 up or, (figure K translated)
  • 6 units right and 4 units down (figure J translated)
