The first picture is correct, the triangle was dilated by a factor of 1/3 and then shifted 2 units down.

The second picture is also correct, because the dots are higher as they move to the right, it is a positive association and they follow a linear line.

Find K by evaluating Limit

Lubov Fominskaja [6]

Answer:

Step-by-step explanation:

$\lim_{x \to \infty}\frac{1-cos4x}{1-cos2x}= \lim_{x \to 0} \frac{(1-cos4x)'}{(1-cos2x)'}= \lim_{x \to 0}\frac{4sin4x}{2sin2x}= \lim_{x \to 0}\frac{2*2sin2xcos2x}{sin2x}\\ = \lim_{x \to 0}4cos2x\\ =4$

{[(3x2)+(5+4)x2]-3}x3=

madreJ [45]

Step-by-step explanation:

Changes made to your input should not affect the solution:

(1): "x3" was replaced by "x^3". 2 more similar replacement(s).

((3•(x2))+(9•(x2)))-3x3

((3 • (x2)) + 32x2) - 3x3

(3x2 + 32x2) - 3x3

Pull out like factors :

12x2 - 3x3 = -3x2 • (x - 4)

-3x^2 • (x - 4)
