Find an equation of the form y=f(x) for a curve with x-intercept 1 whose tangent line at any point (x, y) has slope xe^-y.
y=___

Answer:  [tex]y=\frac{1}{5} x+6[/tex]

Step-by-step explanation:

(-10,4) **substitute these points into the equation below**

y = [tex]\frac{1}{5} x+c[/tex]

4   =  [tex]\frac{1}{5}[/tex][tex](-10)[/tex][tex]+c[/tex] (make c the subject)

c  = 4 + 2

 c = 6 (this is the y-intercept that is needed when creating the equation of the line)

therefore: [tex]y=\frac{1}{5} x+6[/tex]

[tex]\sf y =\dfrac{1}{5} x+6.[/tex]

We're given the slope and an ordered pair the function passes through.

[tex]\sf Slope (m)=\dfrac{1}{5}[/tex]

[tex]\sf Point: (-10,4)\\ \\Therefore:\\x_{1}=-10\\y_{1} =4[/tex]

Here's that formula: [tex]\sf y-y_{1} =m(x-x_{1} )\\ \\[/tex]

[tex]\sf y-(4) =(\dfrac{1}{5} )(x-(-10) )\\ \\[/tex]

[tex]\sf y-(4) =(\dfrac{1}{5} )(x+10 )\\ \\\\\sf y-(4) =(\dfrac{1}{5} )(x)+(\dfrac{1}{5} )(10)\\ \\ \\\sf y-(4) =\dfrac{1}{5} x+(\dfrac{10}{5} )\\ \\ \\\sf y-4 =\dfrac{1}{5} x+2\\ \\ \\\sf y-4+4 =\dfrac{1}{5} x+2+4\\ \\ \\\sf y =\dfrac{1}{5} x+6[/tex]

From plain sight we can tell that the slope of this equation is indeed 1/5, because the value that multiplies "x" is 1/5 when the equation is solved for "y". Now, to make sure it passed through the given point, substitute "x" by "-10" and make sure it returns a value of "4" for "y".

[tex]\sf y =\dfrac{1}{5} (-10)+6\\ \\ \\\sf y =\dfrac{-10}{5}+6\\ \\ \\\sf y =-2+6\\ \\ \\y=4[/tex]

The answer is correct!

Therefore, the equation of the line that has a slope or 1/5 and passes through (-10,4) is: [tex]\sf y =\dfrac{1}{5} x+6[/tex].

Solving an equation we will see that Caitlyn used 3 of the 42-cent stamps and 9 of the 5-cent ones.

Let's define the variables that we will be using:

Then the total value of the stamps, in dollars, is:

x*0.42 + y*0.5

And we know that the value must be $1.71, then we can write the equation:

x*0.42 + y*0.05 = 1.71

y = (1.71 - x*0.42)/0.05

To find the values of x and y, we can just evaluate in different whole values of x, until we get a whole value of y.

using x = 1 we get:

y = (1.71 - 0.42)/0.05 = 2.58

This is not a solution.

if x = 3

y = (1.71 - 0.42*3)/0.05 = 9

A vector (u) with magnitude 4 in the opposite direction as v =⟨−2,3⟩ is u = ⟨-2/√13, 3/√13⟩.

A vector in the opposite direction of a given vector can be found by multiplying that vector by -1. The magnitude of a vector is the length of the vector and it can be found by using the Pythagorean theorem on the coordinates of the vector.

The magnitude of the vector v = ⟨-2,3⟩ is:

|v| = √(-2)^2 + 3^2 = √4 + 9 = √13

To find a vector with magnitude 4 in the opposite direction as v, we can first normalize the vector v by dividing it by its magnitude,

then multiply it by 4:

u = (-1) * (1/|v|) * v

= (-1) * (1/√13) * ⟨-2,3⟩

= ⟨2/√13, -3/√13⟩

So, a vector (u) with magnitude 4 in the opposite direction as v =⟨−2,3⟩ is u = ⟨2/√13, -3/√13⟩

What is circle?

The measurement of the circle's boundaries is called as the circumference or perimeter of the circle. whereas the circumference of a circle determines the space it occupies. The circumference of a circle is its length when it is opened up and drawn as a straight line. Units like cm or unit m are typically used to measure it. The circle's radius is considered while calculating the circumference of the circle using the formula. As a result, in order to calculate the circle's perimeter, we must know the radius or diameter value.

The radius of a circle and its centre angle both affect how long an arc is. We are aware that the arc length and circumference are equivalent at an angle of 360 degrees (2). Due to the continuous relationship between angle and arc length, we can therefore state that:

L/Ф = C/2π

L = C/2π*Ф

A mathematical declaration that two expressions are equal is known as an equation. The equal symbol (=) is used to denote the separation of two phrases.

In the given question, we must isolate the g on one side of the equation in order to solve this equation for g. We may start by multiplying both sides of the equation by 5M to accomplish this. This will result in the left side of the equation having m/5M + ([tex]n^{2}[/tex]/5M). It will only provide us with g on the right side.

The terms on the left side of the equation can then be combined by multiplying them together. This will result in the equation shown below: (m/5M)([tex]n^{2}[/tex]/5M) = g.

The fractions can then be eliminated and the denominators removed by multiplying both sides of the equation by 5M. This will result in the formation of 5Mg on the right side and mn2/5M on the left.

We can then rearrange the equation to isolate the g on the right side, giving us: m[tex]n^{2}[/tex] = 5Mg. Finally, we can divide both sides of the equation by 5M to get g by itself on the right side, giving us the final equation: g = m[tex]n^{2}[/tex]/5M.

What is the exponential function?

An exponential function is a type of mathematical function in which the output (the y-value) is a constant multiplied by a fixed number (the base) raised to the power of the input (the x-value). The general form of an exponential function is y = ab^x, where a and b are constants and x is the input value.

1 .To estimate f(1/3) using the graph points (0, 12) and (1, 0.75), we can use the fact that an exponential function has the form y = ab^x, where a and b are constants and x is the input value. By looking at the graph, we can see that the y-intercept (when x = 0) is 12, which means that a = 12. We can also see that the function passes through the point (1, 0.75), which means that f(1) = 0.75. Using this information, we can write the equation for the function as:

y = 12b^x

f(1/3) = 12b^(1/3)

Since we don't know the value of b, it's impossible to know the exact value of f(1/3) from the given information. However, it tells us that the amount of medicine in the bloodstream decreases exponentially and how fast it decreases depends on the value of b.

2. To find the equation that defines f, we can use the point (1, 0.75). We know that f(1) = 0.75, so we can substitute this into the equation we found earlier:

0.75 = 12b^1

0.75 = 12b

b = 0.0625

So, the equation that defines f is:

y = 12 * 0.0625^x

or

y = 0.75 * 0.0625^x

This equation tells us that the amount of medicine in the bloodstream decreases exponentially with time, with a rate determined by the value of b = 0.0625.

In both cases, the sample proportion is very likely to be within a certain range of the population proportion, with a probability of 1.0000 or 100%.

What is probability?

Probability is a measure of the likelihood that an event will occur, it is a number between 0 and 1, where 0 represents an impossible event and 1 represents a certain event.

In this case, we are interested in the probability that the sample proportion (p) will be within a certain range of the population proportion (0.30).

a. To find the probability that the sample proportion will be within ±0.03 of the population proportion, we can use the standard normal distribution (z-table). The standard normal distribution is a normal distribution with a mean of 0 and a standard deviation of 1.

The formula for the standard normal distribution is:

z = (p - 0.30) / (standard deviation of p)

The standard deviation of p is given by the formula:

(population proportion * (1 - population proportion)) / sample size

In this case, we have:

(0.30 * (1 - 0.30)) / 150 = 0.0006

So, the standard deviation of p is 0.0006

The probability that the sample proportion will be within ±0.03 of the population proportion is the same as the probability that the sample proportion will be between 0.27 and 0.33.

Therefore, we can calculate the z-score for the lower and upper bounds of the range:

z1 = (0.27 - 0.30) / 0.0006 = -5

z2 = (0.33 - 0.30) / 0.0006 = 5

Using the z-table, we can find the probability that a z-score falls between -5 and 5.

The probability that the sample proportion will be within ±0.03 of the population proportion is:

P(z1 <= z <= z2) = P(-5 <= z <= 5) = 1 - 0.0000 = 1.0000

b. To find the probability that the sample proportion will be within ±0.08 of the population proportion, we can use the same formula as before. The probability that the sample proportion will be within ±0.08 of the population proportion is the same as the probability that the sample proportion will be between 0.22 and 0.38.

Therefore, we can calculate the z-score for the lower and upper bounds of the range:

z1 = (0.22 - 0.30) / 0.0006 = -10

z2 = (0.38 - 0.30) / 0.0006 = 10

Using the z-table, we can find the probability that a z-score falls between -10 and 10.

The probability that the sample proportion will be within ±0.08 of the population proportion is:

P(z1 <= z <= z2) = P(-10 <= z <= 10) = 1 - 0.0000 = 1.0000

Hence, In both cases, the sample proportion is very likely to be within a certain range of the population proportion, with a probability of 1.0000 or 100%.

Answer:

$20.44

Step-by-step explanation:

The average of a set of numbers is defined as:

[tex]\dfrac{\textrm{sum of values}}{\textrm{number of values}}[/tex]

In this problem, we are shown a table where each row has a coupon value in the left column and the number of that coupon value in the right column (e.g., if we look at the top row, we can see there are 70 coupons each valued at $10).

So, the sum of values in this problem (i.e., the total number of dollars given out by the store in the form of coupons) is defined as the sum of the product of each row.

[tex]\textrm{sum of values} = (\$10 \times 70) + (\$20 \times 40) + (\$40 \times 20) + (\$60 \times 4) + (\$120 \times 2)[/tex]

[tex]\textrm{sum of values} = \$700 + \$800 + \$800 + \$240 + \$240[/tex]

[tex]\textrm{sum of values} = \$2780[/tex]

The number of values in this problem is just the sum of the numbers in the right column (i.e., the number of coupons given out).

[tex]\textrm{number of values} = 70 + 40 + 20 + 4 + 2[/tex]

[tex]\textrm{number of values} = 136[/tex]

Finally, to answer the problem, we can plug the two numbers that we just solved for into the formula for the average of a set.

[tex]\textrm{average savings} = \dfrac{\textrm{value of all tickets}}{\textrm{number of tickets}}[/tex]

[tex]\textrm{average savings} = \dfrac{\$2780}{136}[/tex]

[tex]\textrm{average savings} \approx \$20.44[/tex]
