2. Use the binomial theorem to expand the expression. (а — 2b)^5

Answers

Answer:

$(a-2b)^(5)=-32b^(5)+80ab^(4)-80a^(2)b^(3)+40a^(3)b^(2)-10a^(4)b+a^(5)$

Step-by-step explanation:

The binomial expansion is given by:

$(x+y)^(n)=_(0)^(n)\textrm{C}x^{^(0)}y^(n)+_(1)^(n-1)\textrm{C}x^(1)y^(n-1)+...+_(n)^(n)\textrm{C}x^(n)y^(0)$

In our case we have

$x=a\ny=-2b\nn=5$

Thus using the given terms in the binomial expansion we get

$(a-2b)^(5)=_(0)^(5)\textrm{C}a^(0)(-2b)^(5)+_(1)^(5)\textrm{C}a^{^(1)}(-2b)^(4)+{_(2)^(5)\textrm{C}}a^(2)(-2b)^(3)+_(3)^(5)\textrm{C}a^(3)(-2b)^(2)+_(4)^(5)\textrm{C}a^(4)(-2b)^(1)+_(5)^(5)\textrm{C}a^(5)(-2b)^(0)$

Upon solving we get

$(a-2b)^(5)=-32b^(5)+5* a*16b^(4)+10* a^(2) * (-8b^(3))+10* a^(3)* 4b^(2)+5* a^(4)* (-2b)+a^(5)\n\n(a-2b)^(5)=-32b^(5)+80ab^(4)-80a^(2)b^(3)+40a^(3)b^(2)-10a^(4)b+a^(5)$

Solve the system using elimination.7x + 10y = 27
X-10y = -19
The solution is
(Simplify your answer. Type an ordered pair.)

Answers

The solution is (1,2)

Step-by-step explanation:

7x + 10y = 27

x - 10y = -19 +--------------------

8x = 8

Divide by 8 on both sides

x = 1

To find y substitute any of the equations to 1

7(1) + 10y = 27

7 + 10y = 27

Substract 7 from both sides

10y = 20

Divide by 10

y = 2

Consider the function below. f(x) = 6x tan x, −π/2 < x < π/2 (a) find the vertical asymptote(s). (enter your answers as a comma-separated list. if an answer does not exist, enter dne.)

Answers

Answer:

x = −π/2, x = π/2

Step-by-step explanation:

Given f(x) = 6x tan x and the interval −π/2 < x < π/2, we know that tan x has asymptotes in both extremes of the interval. To find the vertical asymptotes we evaluate the limit in the x-values we think asymptote can appear, in this case for x = −π/2 and x = π/2.

$\lim_(x \to\ (-\pi/2)-) 6x * tan x=$

$=\lim_(x\to\ (-\pi/2)-) 6x * \lim_(x\to\ (-\pi/2)-)tan x=$

$=-3 \pi * -\infty =\infty$

$\lim_(x\to\ (\pi/2)+) 6x * tan x=$

$=\lim_(x\to\ (\pi/2)+) 6x * \lim_(x\to\ (\pi/2)+)tan x=$

$=3 \pi * \infty =\infty$

Then, x = −π/2 and x = π/2 are vertical asymptotes.

Answer: Does not exist.

Step-by-step explanation:

Since, given function, f(x) = 6x tan x, where −π/2 < x < π/2.

⇒ f(x) = $(6x sin x)/(cosx)$

And, for vertical asymptote, cosx= 0

⇒ x = π/2 + nπ where n is any integer.

But, for any n x is does not exist in the interval ( -π/2, π/2)

Therefore, vertical asymptote of f(x) where −π/2 < x < π/2 does not exist.

?

Answers

Answer:

-1/2

Step-by-step explanation:

The slope formula can be used:

m = (y2 -y1)/(x2 -x1)

m = (-4 -1)/(0 -(-10)) = -5/10

m = -1/2

The slope of the line through the given points is -1/2.

The slope of the line passing through (-10, 1) and (0, -4) is -1/2 the answer is -1/2.

What is the slope?

The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).

$\rm m =(y_2-y_1)/(x_2-x_1)$
