  f(x) = 60.04 – 8.25 ln(x)

_____

The attachment shows the calculator's computation of the model parameters (a₁ and b₁), and is also shows how these parameters might be calculated by hand (a₂ and b₂). The manual calculation involves taking the logarithms of the x-values and computing various means involving those and the y-values. These calculations are easily done on a graphing calculator or spreadsheet, but such a device will also likely be able to compute the regression equation for you.

You can eliminate the first two answer selections because these are not formulas that are logarithmic functions. You can eliminate the last choice because it models values near 8, not near 60. Thus, you can choose the correct answer without knowing much about how to make a logarithmic model.

Answer:

The manufacturer will have no profit or loss when the selling price equals $200 or $100.

Step-by-step explanation:

The expression to model the monthly profit from sales of a new model of bicycle is

-x^2 + 300x -20,000

Let

f(x) -----> the monthly profit in dollars

x -----> s the selling price of one bicycle in dollars

[tex]f(x)= -x^{2}+300x-20,000[/tex]

we know that

The manufacturer will make no profit nor a loss when the profit is equal to zero

so

f(x)=0

[tex]-x^{2}+300x-20,000=0[/tex]

Multiply by -1 both sides

[tex]x^{2}-300x+20,000=0[/tex]

The formula to solve a quadratic equation of the form [tex]ax^{2} +bx+c=0[/tex] is equal to

[tex]x=\frac{-b(+/-)\sqrt{b^{2}-4ac}} {2a}[/tex]

in this problem we have

[tex]a=1\\b=-300\\c=20,000[/tex]

substitute in the formula

[tex]x=\frac{300(+/-)\sqrt{-300^{2}-4(1)(20,000)}}{2(1)}[/tex]

[tex]x=\frac{300(+/-)\sqrt{10,000}}{2}[/tex]

[tex]x=\frac{300(+/-)100}{2}[/tex]

[tex]x=\frac{300(+)100}{2}=200[/tex]

[tex]x=\frac{300(-)100}{2}=100[/tex]

therefore

The manufacturer will have no profit or loss when the selling price equals $200 or $100.

To find the selling prices at which the manufacturer will make neither a profit nor a loss, set the profit expression equal to zero and solve for x, giving a selling price of $5.

To determine the selling prices at which the manufacturer will make neither a profit nor a loss, we set the profit expression equal to zero:

0 = 100x - (500 + 20x)

Solving for x, we get x = 5. This means the selling price for the bicycle to break even is $5.

Answer:

x = - 3

Step-by-step explanation:

Given the 2 equations

y = [tex]\frac{1}{3}[/tex] x + 7 → (1)

y = 3x + 15 → (2)

Since both equations express y in terms of x, equate the right sides

3x + 15 = [tex]\frac{1}{3}[/tex] x + 7

Subtract [tex]\frac{1}{3}[/tex] x from both sides

[tex]\frac{8}{3}[/tex] x + 15 = 7 ( subtract 15 from both sides )

[tex]\frac{8}{3}[/tex] x = - 8 ( multiply both sides by 3 )

8x = - 24 ( divide both sides by 8 )

x = - 3

I would try to avoid unclear statements about the graph and make sure it's clear enough for audience. Also not to use items that bleed through paper.

Answer: Always avoid doing unnecessary things. like changing the zero or using logarithmic scale (and if you use them, mention it), if the graph contains more than one line, then use different colors or dots and label every line.

Also, comparative graphs should always be in the same scale.

a do not replace marbles after picking them;do replace marles

For independent events in probability, you should replace the marbles after picking them, as this keeps the likelihood of each draw the same. For dependent events, do not replace the marbles after picking them, as each draw influences the subsequent draws.

The concept being discussed here is that of independent and dependent events in probability. When selecting marbles from a bag, the nature of the event (whether it is independent or dependent) depends on whether the marble is replaced after being selected or not.

To make your selections independent events, you should replace the marbles after picking them. This assumes that each event (the selection of a marble) does not affect the outcome of the other events. For example, if you picked a blue marble first and replaced it, the likelihood of picking a blue marble on the second draw remains the same.

On the other hand, to create dependent events, you should not replace the marbles after picking them. The outcome of the first event (e.g., removing a blue marble) directly influences the probability of the next event, because there is now one less blue marble in the bag to choose from.

ANSWER

A. Right

EXPLANATION

A tangent to a circle touches the circle at only one point.

The point where a tangent and a radius meet at is called the point of tangency.

The tangent to a circle meets the radius of a circle at a right angle.

This is because the angle between the tangent and the radius of the circle is 90°

The correct answer is A.

Final answer:

When a radius and a tangent intersect at the point of tangency, they form a right angle. This fact is part of basic geometric principles covered in high school mathematics.

Explanation:

The type of angle formed when the radius of a circle and a tangent intersect at the point of tangency is a right angle. This geometric principle is a result of the fact that a tangent to a circle is perpendicular to the radius at the point of tangency. This concept falls within the branch of mathematics known as geometry, which is a crucial topic in high school math education.

Answer:

Option A. [tex]21.21\ units[/tex]

Step-by-step explanation:

we know that

The perimeter of a triangle is equal to the sum of its three side lengths

so

[tex]P=EF+FG+EG[/tex]

the formula to calculate the distance between two points is equal to

[tex]d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}[/tex]

we have

[tex]E(5,4),F(9,1),G(5,-5)[/tex]

step 1

Find the distance EF

[tex]E(5,4),F(9,1)[/tex]

substitute in the formula

[tex]EF=\sqrt{(1-4)^{2}+(9-5)^{2}}[/tex]

[tex]EF=\sqrt{(-3)^{2}+(4)^{2}}[/tex]

[tex]EF=\sqrt{25}[/tex]

[tex]EF=5\ units[/tex]

step 2

Find the distance FG

[tex]F(9,1),G(5,-5)[/tex]

substitute in the formula

[tex]FG=\sqrt{(-5-1)^{2}+(5-9)^{2}}[/tex]

[tex]FG=\sqrt{(-6)^{2}+(-4)^{2}}[/tex]

[tex]FG=\sqrt{52}[/tex]

[tex]FG=7.21\ units[/tex]

step 3

Find the distance EG

[tex]E(5,4),G(5,-5)[/tex]

substitute in the formula

[tex]EG=\sqrt{(-5-4)^{2}+(5-5)^{2}}[/tex]

[tex]EG=\sqrt{(-9)^{2}+(0)^{2}}[/tex]

multiply the second equation by −2

In the addition-subtraction method, the two equations in the system are added or subtracted to create a new equation in one variable. In order for the new equation to have only one variable, the other variable must cancel out.

multiply the second equation by −2:

2x + 4y = 4

−2x − 6y = −26

→ −2y = −22

Answer:

Solution of equation :-

x = 1 or x = -4

Step-by-step explanation:

The given quadratic equation is x² + 3x - 4 = 0

To find the solution

Using splitting method

x² - x + 4x - 4 = 0

x(x - 1) + 4(x - 1) = 0   (take x and 4 as common)

(x - 1)(x + 4) = 0

(x - 1) = 0  or (x +  4)= 0

If x - 1 = 0 then x = 1

If x + 4  = 0 then x = -4

Answer:

Step-by-step explanation:

First get the sum of digits 0 through 9: 0+1+2+...+9=45. Call this sum S for short.

Then notice that the sum of the digits for 10 through 19 is the sum S + 10.

Then notice that the sum of digits 20 through 29 is S + 20, and do so until you hit 100. 100 through 109 is the same as 10 though 19 which you know is S + 10, and finally add the sum of digits of 110, i.e., 2.

Total = S + (S + 10) + (S + 20) + ... + (S + 90) + (S + 10) +2 =

= 11 * S + 10 * (S + 1) + 2 = 11 * 45 + 10 * 46 + 2 = 957

Answer:

957

Step-by-step explanation:

We first calculate the sum of all digits used to write the whole numbers 0 through 99. If we consider all such numbers as two-digit (e.g. write 04 instead of 4), the sum of digits will be unchanged. Then we see that each digit appears an equal number of times in the ones place, and similarly for the tens place, meaning it appears a total of $2\cdot \frac{100}{10} = 20$ times. Thus the sum of all digits used to write the whole numbers 00 through 99 is $20\cdot (0 + 1 +\cdots + 8 + 9) = 900$. The sum of the digits from 100 to 110 is just $(1 + 0) + (1 + 1) + (1 + 2) + \cdots + (1+9) + 2 = 57$. Thus our final answer is $900 + 57 = \boxed{957}$.

Sales tax

At least 20 characters blahhhhh

Answer:

The answer is sales tax.

Step-by-step explanation:

When you purchase an item in a store, you may be charged sales tax.

A typical sales tax is applied at the point of sale and collected by the retailer or seller and then passed on to the government.

There are 6 points on a circle.

We have a sum of angles in a circle that is equal to 360°.

Anna can only see 2 points which is a third of a points there are.

That means her spectrum is 360°/3 which is 120°.

The answer is B. 120°.

Hope this helps.

Brainliest would be amazing.

Final answer:

When six posts are evenly spaced around a circle, they divide the circle into six equal sections of 60 degrees each. If Anna can see across two sections, the measure of angle A (m∠A) is 120 degrees.

Explanation:

In this question, we are asked to find the measure of angle A (m∠A) when six posts are evenly spaced along a circular wall. If six posts are evenly distributed around a circle, they divide the circle into six equal sections. Since a circle has 360 degrees, each section between two posts equals 360°/6 = 60°. When Anna stands at point A, she can see across two such sections, so to find the measure of angle A, we simply add the degrees of the two sections:

Measure of angle A (m∠A) = 60° + 60° = 120°

Therefore, the correct answer to the question is 120°, meaning Anna can see an angle of 120 degrees between the two posts that are visible to her from her standing point at A.

For something to be a function, the input (x value) can ONLY HAVE ONE output (y value), so if x has multiple outputs, it is not a function

B is not a function because x = 2 and x = 9 has 2 outputs

Step-by-step explanation:

A represents a function.  Why?  Because all the x-values are unique (no duplications).

B does not represent a function.  Why?  Because the input 4 is repeated and has different y-values for this one input, and similarly the input 9 is repeated.

The question pertains to engineering, specifically, the equilibrium of beams and structures in statics. Analyzing the forces and torques using equilibrium conditions enables us to determine the support reactions of these structures.

The question involves determining the reactions at the supports of different structures, which is a common problem in statics, a branch of engineering mechanics. This type of problem is typically solved using the principles of equilibrium, where the sum of forces and the sum of moments (torques) about any point must be zero. For beams, bridges, and other structures, the following steps are generally taken:

Working through these problems requires a systematic approach and the application of physics and engineering principles to find the forces and torques on the system.
