Answer:

Option B) Slope = -1

Step-by-step explanation:

For a line passing thru any two points, (x₁, y₁) and (x₂, y₂), its slope is:

\boxed{\mathfrak{slope\:of \:a\: line=\mathsf {\frac{y_2-y_1}{x_2-x_1} }}}

Here, the points are (2, 8) and (4, 6)

therefore,

slope = \mathsf{\frac{6-8}{4-2} }

= \mathsf{\frac{-2}{2} }

= -1

[NOTE: Here, I'm taking (2, 8) as (x₁, y₁), you can take (4, 6) as the latter. The answer obtained in both the cases will be the same.]

SOLUTION We observe that f '(x) = -1 / (1 + x2) and find the required series by integrating the power series for -1 / (1 + x2).
Ann [662]

Answer:

Required series is:

\int{\frac{-1}{1+x^{2}} \, dx =-x+\frac{x^{3}}{3}-\frac{x^{5}}{5}+\frac{x^{7}}{7}+.....

Step-by-step explanation:

Given that

                           f'(x) = -\frac{1}{1 + x^{2}} ---(1)

We know that:

                  \frac{d}{dx}(tan^{-1}x)=\frac{1}{1+x^{2}} ---(2)

Comparing (1) and (2)

                           f'(x)=-(tan^{-1}x) ---- (3)

Using power series expansion for tan^{-1}x

f'(x)=-tan^{-1}x=-\int {\frac{1}{1+x^{2}} \, dx

= -\int{ \sum\limits^{ \infty}_{n=0} (-1)^{n}x^{2n}} \, dx

= -\sum{ \int\limits^{ \infty}_{n=0} (-1)^{n}x^{2n}} \, dx

=-[c+\sum\limits^{ \infty}_{n=0} (-1)^{n}\frac{x^{2n+1}}{2n+1}]

=C+\sum\limits^{ \infty}_{n=0} (-1)^{n+1}\frac{x^{2n+1}}{2n+1}

=C-x+\frac{x^{3}}{3}-\frac{x^{5}}{5}+\frac{x^{7}}{7}+.....

as

                 tan^{-1}(0)=0 \implies C=0

Hence,

\int{\frac{-1}{1+x^{2}} \, dx =-x+\frac{x^{3}}{3}-\frac{x^{5}}{5}+\frac{x^{7}}{7}+.....

Sam took 4 courses last semester: Calculus, Biology, History, and Physics. The means and standard deviations for the final exams
frutty [35]

Answer:

Calculus

Step-by-step explanation:

Calculus: z = (94-70)/12 = 2

Bio: z = (74.5-77)/10 = -0.25

History: z = (45-53)/16 = -0.5

Physics: (70.5-60)/14 = 0.75
