By what percent will the product of two numbers decrease if one of them is decreased by 20% and the other is decreased by 50%?

Answers

Answer 1

Answer:

(x - .20)(x - .50)

[tex]x^{2}[/tex] = (.20)(.50)

[tex]x^{2}[/tex] = 0.1

x = [tex]\sqrt{ .1[/tex]

x = .32

the product of two numbers decrease by 32%

A computer cost $800. It loses 1/4 of its value every year after it is purchased. complete the table to show the value of the computer at the listed times. Write an equation representing the values, v, of the computer, years after it is purchased. Used your equation to find v when t is 5. What does this value of v mean?

Answers

Answer:

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:

he cost of computer = $ 800It losed 1/4th of value every year.The value of computer after 0 years = cost of computer = $ 800The value after 1 year = 800 - ( ) = $600The value after 2 years = 600 - ( ) = $450The value after 3 years = 450 - ( ) = $337.5The value after n years = computer cost at (n-1) year -

We can conclude that -

the equation representing the value {v} of the computer, years after it is purchased as → v{x} = 800(1/4)ˣ.For {x} = 5, the value of {v} would be 0.39.

What is function?

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 -

the equation representing the value {v} of the computer, years after it is purchased as → v{x} = 800(1/4)ˣ.For {x} = 5, the value of {v} would be 0.39.

The base of a triangle is 6 meters longer than the height of the triangle. If the area of the triangle is 56
square meters, what are the base and height of the triangle?
The height is
meters
The base is
meters

PLEASE HELP FOR EXAM

Answers

Answer:

Height = 8

Base = 14

Step-by-step explanation:

Base=x+6

Height=x

Area of a triangle is 1/2bh.

1/2·x·(x+6)=56

x²+6x=112

x²+6x-112=0

(x+14)(x-8)=0

x=-14 or x=8

Since x can’t equal a negative number, it must be 8.

Height=x = 8

Base=x+6 = 8+6 = 14

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

Answers

Answer:

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

Step-by-step explanation:

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

Use the definition of a Taylor series to find the first four nonzero terms of the series for f(x) centered at the given value of a. (Enter your answers as a comma-separated list.) f(x) = 7xex, a = 0

Answers

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]

If mSW = (12x-5)°, mTV= (2x+7)°,and m angle TUV = (6x-19)°, find mSW

Answers

Given:

Consider the below figure attached with this question.

m(arc(SW)) = (12x-5)°, m(arc(TV))= (2x+7)°,and measure of angle TUV = (6x-19)°.

To find:

The m(arc SW).

Solution:

Intersecting secant theorem: If two secants intersect outside the circle, then the angle on the intersection is half of the difference of the larger subtended arc and smaller subtended arc.

Using Intersecting secant theorem, we get

[tex]m\angle TUV=\dfrac{1}{2}(m(arc(SW))-m(arc(TV)))[/tex]

[tex]6x-19=\dfrac{1}{2}((12x-5)-(2x+7))[/tex]

[tex]6x-19=\dfrac{1}{2}(12x-5-2x-7)[/tex]

[tex]6x-19=\dfrac{1}{2}(10x-12)[/tex]

Multiply both sides by 2.

[tex]2(6x-19)=10x-12[/tex]

[tex]12x-38=10x-12[/tex]

[tex]12x-10x=38-12[/tex]

[tex]2x=26[/tex]

Divide both sides by 2.

[tex]x=13[/tex]

Now, the measure of arc SW is:

[tex]m(arc(SW))=(12x-5)^\circ[/tex]

[tex]m(arc(SW))=(12(13)-5)^\circ[/tex]

[tex]m(arc(SW))=(156-5)^\circ[/tex]

[tex]m(arc(SW))=151^\circ[/tex]

Therefore, the measure of arc SW is 151 degrees.

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.

What is transformation on the graphs?

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.

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]

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]
