Answer 1

In order to determine the corresponding graph to the given function f(x), consider the y-intercept of the function (the value of the y-coordinate of the curve when x = 0).

The y-intercept is the value of f(x) for x= 0. Replace x = 0 into the given function:

[tex]f(0)=(\frac{1}{2})^{0+1}+3=\frac{1}{2}+3=\frac{7}{2}[/tex]

Then, the point of intersection of the curve with the y-axis is (0 , 7/2) or (0 , 3.5).

You can notice that from the given answer choices, that option two (up right side) has the required y-intercept. Then, that graph matches with the given function.

which of the following statements is correct?A XYZ ~ wvz by AA similarityB XYZ ~ WVZ by SAS similarityC XYZ ~ WVZ by SSS similarityD XYZ and WVZ are not similar

Answers

We have two triangles, XYZ and WVZ.

They shared the vertex Z, formed by the intersection of two lines, XW and VY.

Also, XY and VW are parallel.

Then, we have a pair of congruent angles at vertex Z, as they are vertical angles.

We also have another pair of congruent angles: V and Y, because they are alternate interior angles between parallel lines.

Then, as we have two pair of congruent angles, the third pair of angles have to be congruent too, as the measures of the interior angles of a triangle always add 180°.

Then, if we have 3 pair of congruent angles, we have similar triangles.

We can not say anything about congruent sides because we don't know any relation or proportion between them, so the other postulates, SAS or SSS, can not be used.

We also have

[tex]m\angle AFB=m\angle EFC\text{ (Vertically opposite angl}es)[/tex]

Remember that the sum of angles at a point equals 360°. Therefore

[tex]\begin{gathered} m\angle AFB+m\angle BFC+m\angle CFE+m\angle AFE=360 \\ \therefore we\text{ have} \\ 2(m\angle AFB)+2(70)=360 \\ 2(m\angle AFB)=360-140=220 \\ m\angle AFB=\frac{220}{2}=110 \end{gathered}[/tex]

Each person will occupy his or her own entire floor and no other people will be in the dormitory. The assignment of people to floors must follow the following rules:Eugenio lives immediately above Damaris.Cindy is not on the first floor.Fareed does not live immediately below Damaris.Guzal lives either on the first floor or the fifth floor.Which one of the five people could be assigned to live on any of the five floors in the dormitory? A. Cindy B. Damaris C. Eugenio D. Fareed E. Guzal2. If Fareed lives neither directly above nor directly below Cindy in the dormitory, which one of the following people must live on the fourth floor? A. Cindy B. Damaris C. Eugenio D. Fareed E. Guzal

Answers

SOLUTION

(1) From the question, if Eugene lives immediately above Damaris, then Eugene can only live between floors 1 to 4.

And Damaris can only live between floors 2 to 5.

Guzal can only live on floors 1 or 5

Siince Cindy cannot live on the first floor, she can only live between floors 2 to 5, Since Fareed does not live immediately below Damaris. Fareed can live between floors 1 to 5.

Hence the answer is Fareed, option D

Is the function y= –10x10–10 linear or nonlinear?

Answers

The function y = -10*x¹⁰ - 10

Is not a linear function, as we can see the exponent is 10.

Is the function linear or non-linear?

Remember that a linear function is of the form:

y = m*x + b

Where x is the variable.

So a linear function is a polynomial of degree 1.

Particularly, here we have the function:

y = -10*x¹⁰ - 10

So we have an exponent of 10, which means that this is not a linear function.

The scatter plot shows the number of CDs in millions that were sold from 1999 to 2005. Use the points (1999,940) and (2002,805) to find a line of fit for the data. Then use the line of fit to estimate the number of CDs that were sold in 2008

Answers

Based on the given points from the scatter plot on the number of CDs sold in millions, the line of best fit for the data is y = -45x + 90,895

The estimated number of CDs sold in 2008 was 535 CDs.

How to find the line of best fit?

The line of best fit will take the form:
y = Slope(x) + y intercept

The value of x will be assumed to be the number of years since 1999.

The slope is:

= Change in y / Change in x

= (805 - 940) / (2002 - 1999)

= -45

The y intercept is:
940 = -45(3) + y

y = 90,895

The line of best fit is:

y = -45x + 90,895

This means that the number of CDs sold in 2008:

= -45(2008) + 90,895

= 535 CDs

where (x2,y2) is the rightmost point and (x1,y1) is the other point

If i have two points (3,4) and (6,2)

the rigthmost point is (6,2) because 6 is greater than 3 and these two numbers are x, the place where I can locate myself horizontally or left or right

Answers

To evaluate the expression with the given values, we need to substitute them and perform any required calculation.

To do so, we need to remember the following rule:

If we have a multiplication of two numbers with different signals, one of them positive and the other negative, the result will be negative. If the multiplication is made with two numbers with the same signal, both positive or both negative, the result will be positive.

From this, we perform the following calculation:

The price of a notebook has risen to $3.35 today. Yesterday's price was $3.10. Find the percentage increase. Round your answer to the nearest tenth of a percent.

Answers

The percent of increasing = amount of increasing/original amount x 100%

Since the price of the notebook on one day is $3.10

Since it is increased to $3.35

Then the amount of increasing = 3.35 - 3.10 = 0.25 dollars

Since the original price is 3.10

By using the rule above

[tex]\text{Percent}=\frac{0.25}{3.10}\times100[/tex]

The percent of increasing = 8.064516%

Round it to the nearest tenth

The percent of the increase is 8.1%

Answers

[tex]\text{Area}=84.87(cm^2)[/tex]

Explanation

Step 1

draw the rectangle

here we have a rigth triangle,then

Let

[tex]\begin{gathered} hypotenuse=14 \\ agle=30\text{ \degree} \\ \text{adjacent side= length= l} \end{gathered}[/tex]

so, we need a function that relates those values

[tex]\cos \Theta=\frac{adjacent\text{ side}}{\text{hypotenuse}}[/tex]

replace and solve for length

[tex]\begin{gathered} \cos \Theta=\frac{adjacent\text{ side}}{\text{hypotenuse}} \\ \text{hypotenuse}\cdot\cos \Theta=adjacent\text{ side} \\ 14\text{ cm }\cdot\cos 30=l \\ 12.12435\text{ cm=l} \end{gathered}[/tex]

Step 2

width

similarity, we need a function that relates

[tex]\sin \text{ }\Theta=\frac{opposite\text{ side}}{\text{hypotenuse}}[/tex]

let

[tex]\text{opposite side= width=w}[/tex]

replace and solve for w

[tex]\begin{gathered} \sin \text{ }\Theta=\frac{opposite\text{ side}}{\text{hypotenuse}} \\ \text{hypotenuse}\cdot\sin \Theta=opposite\text{ side} \\ 14\text{ cm }\cdot\sin \text{ 30=w} \\ 7cm=w \end{gathered}[/tex]

Step 3

finally, the area of a rectangle is given by

[tex]\begin{gathered} \text{Area}=\text{ length }\cdot width \\ \text{replacing} \\ \text{Area}=(12.12\cdot7)(cm^2) \\ \text{Area}=84.87(cm^2) \end{gathered}[/tex]

therefore, the answer is

[tex]\text{Area}=84.87(cm^2)[/tex]
