What is the explicit formula for the sequence below?<br><br> 4, -12, 36, -108 ...
Temka [501]

Answer:

This is a geometry sequence (I.e each term is found by multiplying the same value to the previous term).

T1 = 4

T2 = -12 = T1 X (-3) = 4 X (-3)

T3 = 36 = T2 X (-3) = 4 X (-3)^2

T4 = 108 = T3 X (-3) = 4 X (-3)^3

The general (explicit) formula for the n-th term of this sequence is:

S(n) = 4 X (-3)^(n-1)

Help pleaseeeeeeeeeeeeeee
TEA [102]

Answer:

54m2

Step-by-step explanation:

Cut the shape into two - from the 9m length. One has 3m by 8m(ie 5m + 3m) dimensions, and the other 6m(ie 9m - 3m) by 5m dimensions.

Taking area of first one=24m2,then area of the second =30m2.

To get area of whole shape, we add both areas=54m2

NB:Area=l×b

The point A(–1, 4) is translated five units right and three units down. Which rule describes the translation?
lozanna [386]

Answer: SECOND OPTION.

Step-by-step explanation:

Given the following point identified as "A":

A(-1,4)

You can identify that the x-coordinate of the point is:

x=-1

And its y-coordinate is:

y=4

According to the exercise, this point is translated five units right and three units down. This means that, in order to find the new coordinates, you need to add 5 to the original x-coordinate and subtract 3 from the original y-coordinate.

Therefore, you can conclude that the rule that best describe the translation of the point A(-1,4) is the following:

(x,y) → (x+5,y-3)

Then, the point translated is:

A'(-1+5,\ 4-3) → A'(4,1)
