Expand the following using the Binomial Theorem and Pascal’s triangle (2x − 3y)^4
krok68 [10]

Answer:

Step-by-step explanation:

Binomial Expansion:

(2x-3y)^4 \\\\= 4C_0(2x)^4 (-3y)^0 + 4C_1(2x)^3 (-3y)^1 + 4C_2(2x)^2(-3y)^2 \\\\+ 4C_3(2x)^1 (-3y)^3 + 4C_4(2x)^0 (-3y)^4\\\\=16x^4 + 4(8x^3)(-3y) + 6(4x^2)(9y^2) + 4(2x)(-27y^3) + 81y^4\\\\=16x^4 - 96x^3y + 216x^2y^2-216xy^3 +81y^4

Pascal's Triangle:

  Zero row                        1

 First row                  1                 1

 Second row          1           2             1

 Third  row         1         3              3          1

navik [9.2K]

Answer:

\large \boxed{\mathbf{y = 2.538e^{0.6699x}}}

Step-by-step explanation:

x 0  1  2  3   4   5   6     7

y 2 6 12 17 36 72 138 275

The points appear to follow an exponential growth curve.

The regression equation is

\large \boxed{\mathbf{y = 2.538e^{0.6699x}}}

The figure below shows the graph of your points and the regression line.
