Which expression represents the sixth term in binomial expansion (2a-3b)^10

Mathematics

AysviL [449]3 years ago

Therefore the sixth term in the binomial expansion is=-{10}C_5(2a)^{5} (3b)^5

Step-by-step explanation:

Given

(2a -3b)^{10}

=^{10}C_0 (2a)^{10} + ^{10}C_1(2a)^9(-3b)+^{10}C_2(2a)^8(-3b)^2+...............+^{10}C_10(-3b)^{10}

So,

T_{n+1}= ^{10}C_n(2a)^{(10-n)} (-3b)^n

T_6=T_{(5+1)} =^{10}C_5(2a)^{10-5} (-3b)^5

Therefore the sixth term in the binomial expansion is= {10}C_5(2a)^{10-5} (-3b)^5

                                                                                         =-{10}C_5(2a)^{5} (3b)^5

Solve for x in the equation x^2+4x-4=8
quester [9]
I will get you started.

x^2+4x-4 = 8

x^2 + 4x - 4 - 8 = 0

x^2 + 4x - 12 = 0

You must now use the quadratic formula.

In the formula, a = 1, b = 4, and c = -12.

Take it from here.

Consider the line x+5y=6
Tems11 [23]

Answer:

x + 5y = 6 is perpendicular to y = 5x + \frac{6}{5} and parallel to y = -\frac{1}{5}x + 2\\

Step-by-step explanation:

First, convert the equation to standard form so that y is isolated.

x + 5y = 6 --> x - 6 = -5y (divide both sides by -5) --> y = -\frac{1}{5}x + \frac{6}{5}

A perpendicular line will have a slope that is the opposite reciprocal of the original slope (meaning you flip the numerator and denominator then make it negative).

-\frac{1}{5} is perpendicular to -(\frac{-5}{1} ) which simplifies to 5.

A parallel line will have the same slope, but the y-intercept will be different. It can be pretty much any number as long as the original slope is used in the new equation.

y = -\frac{1}{5}x + \frac{6}{5}\\ is parallel to y = -\frac{1}{5}x + 2\\ just like y = -\frac{1}{5}x - \frac{100}{23}.
