of citizens over 60 years of age whose net worth is too high to qualify for Medicaid. The ages of 25 senior citizens were as provided. Determine which of the statements below is true.
60 61 62 63 64 65 66 68 68 69 70 73 73 74 75 76 76 81 81 82 86 87 89 90 92

Answer:

median value = 73 years

Step-by-step explanation:

The median age of the uninsured senior citizens can be determined by determining the middle position of the row of data given

median = [( n + 1 ) / 2 ] ^th

n = 25

median = (25 + 1 ) / 2 = 26 / 2 = 13

This means that the median value is located in the 13th position

The number in the 13th position = 73 years

This problem asks for Taylor polynomials forf(x) = ln(1 +x) centered at= 0. Show Your work in an organized way.(a) Find the 4th,
stich3 [128]

Answer:

a) The 4th degree , 5th degree and sixth degree polynomials

f^{lV} (x) = \frac{(2(-3))}{(1+x)^4} (1)= \frac{((-1)^3(3!))}{(1+x)^4}

f^{V} (x) = \frac{(2(-3)(-4))}{(1+x)^5} =\frac{(-1)^4 (4!)}{(1+x)^5}

f^{V1} (x) = \frac{(-120))}{(1+x)^6} (1) = \frac{(-1)^5 5!}{(1+x)^6}

b)The nth degree Taylor polynomial for f(x) centered at x = 0, in expanded form.

log(1+x) = x - \frac{x^2}{2} +\frac{x^3}{3} - \frac{x^4}{4} + \frac{x^5}{5} - \frac{x^6}{6}+\\..  (-1)^{n-1}\frac{x^n}{n} +..

Step-by-step explanation:

Given the polynomial function f(x) = log(1+x) …...(1) centered at x=0

      f(x) = log(1+x) ……(1)

using formula \frac{d}{dx} logx =\frac{1}{x}

Differentiating Equation(1) with respective to 'x' we get

f^{l} (x) = \frac{1}{1+x} (\frac{d}{dx}(1+x)

f^{l} (x) = \frac{1}{1+x} (1)  ….(2)

At x= 0

f^{l} (0) = \frac{1}{1+0} (1)= 1

using formula \frac{d}{dx} x^{n-1}  =nx^{n-1}

Again Differentiating Equation(2) with respective to 'x' we get

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

f^{ll} (x) = \frac{-1}{(1+x)^2} (1)    ….(3)

At x=0

f^{ll} (0) = \frac{-1}{(1+0)^2} (1)= -1

Again Differentiating Equation(3) with respective to 'x' we get

f^{lll} (x) = \frac{(-1)(-2)}{(1+x)^3} (\frac{d}{dx}((1+x))

f^{lll} (x) = \frac{(-1)(-2)}{(1+x)^3} (1)=  \frac{(-1)^2 (2)!}{(1+x)^3} ….(4)

At x=0

f^{lll} (0) = \frac{(-1)(-2)}{(1+0)^3} (1)

f^{lll} (0) = 2

Again Differentiating Equation(4) with respective to 'x' we get

f^{lV} (x) = \frac{(2(-3))}{(1+x)^4} (\frac{d}{dx}((1+x))

f^{lV} (x) = \frac{(2(-3))}{(1+x)^4} (1)= \frac{((-1)^3(3!))}{(1+x)^4} ....(5)

f^{lV} (0) = \frac{(2(-3))}{(1+0)^4}

f^{lV} (0) = -6

Again Differentiating Equation(5) with respective to 'x' we get

f^{V} (x) = \frac{(2(-3)(-4))}{(1+x)^5} (\frac{d}{dx}((1+x))

f^{V} (x) = \frac{(2(-3)(-4))}{(1+x)^5} =\frac{(-1)^4 (4!)}{(1+x)^5} .....(6)

At x=0

f^{V} (x) = 24

Again Differentiating Equation(6) with respective to 'x' we get

f^{V1} (x) = \frac{(2(-3)(-4)(-5))}{(1+x)^6} (\frac{d}{dx}((1+x))

f^{V1} (x) = \frac{(-120))}{(1+x)^6} (1) = \frac{(-1)^5 5!}{(1+x)^6}

and so on...

The nth term is

f^{n} (x) =  = \frac{(-1)^{n-1} (n-1)!}{(1+x)^n}

Step :-2

Taylors theorem expansion of f(x) is

f(x) = f(a) + \frac{x}{1!} f^{l}(x) +\frac{(x-a)^2}{2!}f^{ll}(x)+\frac{(x-a)^3}{3!}f^{lll}(x)+\frac{(x-a)^4}{4!}f^{lV}(x)+\frac{(x-a)^5}{5!}f^{V}(x)+\frac{(x-a)^6}{6!}f^{VI}(x)+...….. \frac{(x-a)^n}{n!}f^{n}(x)

At x=a =0

f(x) = f(0) + \frac{x}{1!} f^{l}(0) +\frac{(x)^2}{2!}f^{ll}(0)+\frac{(x)^3}{3!}f^{lll}(0)+\frac{(x)^4}{4!}f^{lV}(0)+\frac{(x)^5}{5!}f^{V}(0)+\frac{(x)^6}{6!}f^{VI}(0)+...….. \frac{(x-0)^n}{n!}f^{n}(0)

Substitute  all values , we get

f(x) = f(0) + \frac{x}{1!} (1) +\frac{(x)^2}{2!}(-1)+\frac{(x)^3}{3!}(2)+\frac{(x)^4}{4!}(-6)+\frac{(x)^5}{5!}(24)+\frac{(x)^6}{6!}(-120)+...….. \frac{(x-0)^n}{n!}f^{n}(0)

On simplification we get

log(1+x) = x - \frac{x^2}{2} +\frac{x^3}{3} - \frac{x^4}{4} + \frac{x^5}{5} - \frac{x^6}{6}+\\..  (-1)^{n-1}\frac{x^n}{n} +..

The lateral area of a right prism having a perimeter of 25 inches and a height of 5 inches is?
Pepsi [2]

Answer:

The lateral area is LA=125\ in^{2}

Step-by-step explanation:

we know that

The lateral area of a right prism is equal to

LA=PH

where

P is the perimeter of the base of the prism

H is the height of the prism

in this problem we have

P=25\ in

H=5\ in

substitute

LA=(25)(5)=125\ in^{2}

Find the average rate of change of the exponential equation from x = 3 to x = 6
umka2103 [35]

The average rate of change of the exponential equation from x = 3 to x = 6 is 4.55

<h3>How to determine the average rate of change?</h3>

The function is given as:

f(x) = 2x^{1.35

When x = 3, we have:

f(3) = 2 * 3^{1.35} =8.813

When x = 6, we have:

f(6) = 2 * 6^{1.35} =22.466

The average rate of change is then calculated as:

m = \frac{f(6) -f(3)}{6 - 3}

This gives

m = \frac{22.466 -8.813}{6 - 3}

Evaluate

m = 4.55

Hence, the average rate of change of the exponential equation from x = 3 to x = 6 is 4.55
