Sphinxa [80]3 years ago

The first term of this sequence is -20, and the common ratio is 11. Thus, the formula for the nth term is

a(n) = a(1)*(11)^(n-1), or (-20)*(11)^(n-1).

Thus, the 12th term is

a(12) = (-20)*(11)^(12-1) = -20(11)^11 = -20(2.85 times 10 to the 11th power.

or ... -5.71 times 10 to the 12th power.

1/4k = 3 (-1/4k + 3)​
Arada [10]

Answer:

For the expression \frac{1}{4} k = 3 (-\frac{1}{4}k  +3)

k = 9 is the required solution.

Step-by-step explanation:

Here, the given expression is \frac{1}{4} k = 3 (-\frac{1}{4}k  +3)

Solving the above expression for k, we get:

\frac{1}{4} k = 3 (-\frac{1}{4}k  +3)  \implies  \frac{k}{4}  = (\frac{-3}{4}k) + 9

or, \frac{k}{4}  + (\frac{3}{4}k) =  9 \implies \frac{k + 3k}{4}   = 9

or, \frac{4k}{4}  = 9  \implies   k =9

or, k = 9

Hence for the expression \frac{1}{4} k = 3 (-\frac{1}{4}k  +3)

k = 9 is the required solution.

Find the coordinates of the vertices of the figure after the given transformation T <2,4>
tankabanditka [31]

The correct answer is option A which is j'(1,3) , E'( -2,1) and V'( 1,3).

<h3>What is coordinate geometry?</h3>

A coordinate plane is a 2D plane that is formed by the intersection of two perpendicular lines known as the x-axis and y-axis.

Given that:-

  • The coordinates of the vertices of the figure after the given transformation T <2,4>

So we will transform the points given in the figure.

V(-1,-1) , J(-4,-5) and E(-4,-3).

The transformation will be given as:-

V(-1,-1)  → V'(-1+2 , -1 + 4)      → V'( 1,3 )

J(-4,-5) → J'( -4 +2 , -5 + 4 )  → J'( -2,-1 )

E(-4,-3). → E'( -4+2 , -3+4 )   → E' ( -2, 1 )

Therefore  correct answer is option A which is j'(1,3) , E'( -2,1) and V'( 1,3).
