The graph of the function [tex]f(x) = \frac 14(4)^x[/tex] is (d) on a coordinate plane, an exponential function approaches y = 0 in quadrant 2 and goes through points (1, 1) and (2, 4).

Functions are used to represent equation, graphs and tables

The equation of the function is given as:

[tex]f(x) = \frac 14(4)^x[/tex]

The above function is an exponential function that has an initial value of 1/4 and a rate of 4

When x = 2,

f(2) = 4

When x = 1,

f(1) = 1

Hence, the graph of the function [tex]f(x) = \frac 14(4)^x[/tex] is (d)

Answer:

The four first terms are:

[tex]7x,7x^{2},\frac{21x^{3}}{6},\frac{7x^{4}}{6}[/tex]

Step-by-step explanation:

The function is:

[tex]f(x)=7xe^{x}[/tex]

The Taylor series around a is given by:

[tex]F(x)=\sum^{\infty}_{n=0} \frac{f^{n}(a)(x-a)^{n}}{n!}[/tex]

The first 4 terms will be:

[tex]F(x)=f(0)+\frac{f^{'}(0)(x)}{1}+\frac{f^{''}(0)(x)^{2}}{2}+\frac{f^{'''}(0)(x)^{3}}{6}[/tex]  

Let's find first the derivatives:

[tex]f'(x)=7(xe^{x}+e^{x})[/tex]

[tex]f'(0)=7(0e^{0}+e^{0})=7[/tex]

[tex]f''(x)=7xe^{x}+7e^{x}+7e^{x}=7xe^{x}+14e^{x}[/tex]  

[tex]f''(0)=14[/tex]  

[tex]f'''(0)=21[/tex]

[tex]f''''(0)=28[/tex]    

[tex]F(x)=0+\frac{7(x)}{1}+\frac{14(x)^{2}}{2}+\frac{21(x)^{3}}{6}+\frac{28(x)^{4}}{24}[/tex]

Therefore, the four first terms are:

[tex]7x,7x^{2},\frac{21x^{3}}{6},\frac{7x^{4}}{6}[/tex]

I hope it helps you!

So the Taylor series for the function informed will be:

[tex]7x; 7x^2; \frac{21x^3}{6} ; \frac{7x^4}{6}[/tex]

The function is:

[tex]f(x)= 7e^xx[/tex]

The Taylor series around a is given by:

[tex]f(x)= \sum \frac{f^n (a) (x-a)^n }{n!}[/tex]

The first four terms will be:

[tex]F(x)=f(0)+\frac{f'(0)(x)}{1}+\frac{f''(0)(x)^2}{2} + \frac{f'''(0)(x)^3}{6}[/tex]

Let's find first the derivaties:

[tex]f'(x)= 7(e^xx+e^x)\\f'(0)= 7\\f''(x)= 7e^xx+14e^xx\\f''(0)=14\\f'''(0)= 21\\f''''(0)= 28[/tex]

[tex]F(x)= 0+\frac{7x}{1}+\frac{14x^2}{2}+\frac{21x^3}{6}+\frac{28x^4}{24}[/tex]

Therefore, the four first terms are:

[tex]7x; 7x^2; \frac{21x^3}{6} ; \frac{7x^4}{6}[/tex]

Answer:

Step-by-step explanation:

A). From the table of relative frequencies,

Let the relative frequency of women who prefer mineral water = x

Total of relative frequencies of women preferring purified water and mineral water = 0.59

Since, Total of relative frequencies of women who prefer purified water and mineral water = Relative frequency of women preferring purified water + Relative frequency of women preferring mineral water

0.59 = 0.14 + x

x = 0.59 - 0.14

x = 0.45

B). Relative frequency of men  who prefer mineral water = 0.13

Let the frequency of men who prefer mineral water = x

Since, relative frequency = [tex]\frac{\text{Frequency}}{\text{Total of frequencies}}[/tex]

0.13 = [tex]\frac{x}{200}[/tex]

x = 200 × 0.13

x = 26

Therefore, number of shoppers who are men and prefer mineral water = 26

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Mean waiting time of 20 minutes with a standard deviation of 5 minutes.

This means that [tex]\mu = 20, \sigma = 5[/tex]

What percentage of the people in line waited for more than 28 minutes?

The proportion is 1 subtracted by the p-value of Z when X = 28. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{28 - 20}{5}[/tex]

[tex]Z = 1.6[/tex]

[tex]Z = 1.6[/tex] has a p-value of 0.9452.

1 - 0.9452 = 0.0548.

As a percentage:

0.0548*100% = 5.48%

5.48% of the people in line waited for more than 28 minutes

Given:

The line passes through the two points (–4, –3) and (12, 1).

The point-slope form of the equation of the line is:

[tex]y-1=\dfrac{1}{4}(x-12)[/tex]

To find:

The standard form of the equation for this line.

Solution:

The standard form of a line:

[tex]Ax+By=C[/tex]

The given point-slope form of the equation of the line is:

[tex]y-1=\dfrac{1}{4}(x-12)[/tex]

Multiply both sides by 4.

[tex]4(y-1)=(x-12)[/tex]

[tex]4y-4=x-12[/tex]

[tex]-4+12=x-4y[/tex]

[tex]8=x-4y[/tex]

Interchanging the sides, we get

[tex]x-4y=8[/tex]

Therefore, the standard form of the equation for this line is [tex]x-4y=8[/tex].

Step-by-step explanation:

Given

[tex]h = 14in[/tex] --- height

[tex]d =4.5in[/tex] --- diameter

Required

The minimum amount of paper needed

This implies that we calculate the surface area of the can (cylinder)

This is calculated as:

[tex]Area = 2\pi r(r + h)[/tex]

Where

[tex]r = \frac{1}{2}d[/tex]

So, we have:

[tex]r = \frac{1}{2} *4.5[/tex]

[tex]r = 2.25[/tex]

This gives:

[tex]Area = 2 * 3.14 * 2.25(2.25 + 14)[/tex]

[tex]Area = 2 * 3.14 * 2.25*16.25[/tex]

[tex]Area = 229.6125in^2[/tex]

Step-by-step explanation:

The graph of F(x), shown below, resembles the graph of G(x) = x2, but it has been changed somewhat. Which of the following could be the equation of F(x)?

The function that represents the situation is F(x) = -x² - 3.

The correct option is A.

Let the functions f(x) and g(x) be two real functions.

And g (x) = f (x) + k, where k is real numbers.

The function can be sketched by shifting f (x), k units vertically.

The value of k can find the direction of shift:

if k > 0, the base graph shifts k units up, and

if k < 0, the base graph shifts k units down.

Given that the parent function is g(x) = x².

To find the transformed function F(x):

The function's diagram is in the opposite direction.

That means the function is -x².

And the function is shifted 3 units down vertically.

From the definition the required function is,

F(x) = -x² - 3.

Therefore, F(x) = -x² - 3.

The value after 0 years = $ 800

The value after 1 year = $600

The value after 2 years = $450

The value after 3 years = $337.5

The value after n years = computer cost at (n-1) year -

Step-by-step explanation:

We can conclude that -

A function is a relation between a dependent and independent variable. We can write the examples of functions as -

y = f(x) = ax + b

y = f(x, y, z) = ax + by + cz

Given is that a computer cost $800. It loses 1/4 of its value every year after it is purchased.

We can write the equation representing the value {v} of the computer,

years after it is purchased as -

v{x} = 800(1/4)ˣ

For {x} = 5, we can write -

v{5} = 400(1/4)⁵

v{5} = 400 x 0.0009765625

v{5} = 0.39

Therefore, we can conclude that -
