The intersection points are: (0, -3) and (10, 2)

The bounded area is -20.83 unit²

(a) The  intersection points of the line and curve are the points where the line and curve meet. Thus, the intersection points are:

(0, -3) and (10, 2)

(b) The integral terms of y which gives the area bound are:

a = -3, b = 2 (These are the y values of the intersection points)

Since we have x = y² + 3y and x = 2y + 6, we can say:

y² + 3y = 2y + 6

y² + 3y - 2y - 6 = 0

y² + y - 6 = 0

Thus, h(y) =

Using a = -3 and b = 2  with h(y) = y² + y - 6, we have the bounded area as:

[tex]Area = \int\limits^b_a {y} \, dy[/tex]

[tex]Area = \int\limits^{2}_{-3} {(y^{2} + y - 6}) \, dy[/tex]

Integrating the area:

Area = [y³/3 + y²/2 - 6y + C]²₋₃

Area = [2³/3 + 2²/2 - 6(2)] - [(-3)³/3 + (-3)²/2 - 6(-3)]

Area = [8/3 + 2 - 12] - [-9 + 4.5 + 18]  

Area = [-22/3] - [27/2]

Area = -125/6

Area = -20.83 unit²

Answer: $1.46 less

Step-by-step explanation:

Lets find how much each bottle is first for Store B, to do that divide 29.10 divided by 15 and you should get 1.94 meaning each bottle of juice is $1.94. Next, lets find how much each bottle costs in store A. You can take any number from the total cost and divide it by the bottles and you should get the same thing. Lets do the first one 2.40 divided by 5 equals 0.48. If you want to check you can multiply 0.48 by any number of bottles and you should get the total cost. Now we have to find how much less Store A costs, to do so we subtract store B (1.94) and store A (0.48) and you should get $1.46.

Step-by-step explanation:

The formula to find the surface area of a cylinder is as follows: SA= (2*π*r*h) + (2*π*r²)

You need to know the height of the cylinder in order to input the number into the equation.

Also, if you are using nets, you need to know the height of the cylinder because you cannot calculate the area of the rectangle part of the cylinder's net without that measurement.

keeping in mind that perpendicular lines have negative reciprocal slopes, let's check for the slope of the equation above

[tex]6x+y=-10\implies y=-6x-10\qquad \impliedby \qquad \begin{array}{|c|ll} \cline{1-1} slope-intercept~form\\ \cline{1-1} \\ y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \\\\ \cline{1-1} \end{array} \\\\[-0.35em] ~\dotfill[/tex]

[tex]\stackrel{~\hspace{5em}\textit{perpendicular lines have \underline{negative reciprocal} slopes}~\hspace{5em}} {\stackrel{slope}{ -6 \implies \cfrac{-6}{1}} ~\hfill \stackrel{reciprocal}{\cfrac{1}{-6}} ~\hfill \stackrel{negative~reciprocal}{-\cfrac{1}{-6} \implies \cfrac{1}{ 6 }}}[/tex]

so we're really looking for the equation of a line whose slope is 1/6 and it passes through (1 , 1)

[tex](\stackrel{x_1}{1}~,~\stackrel{y_1}{1})\hspace{10em} \stackrel{slope}{m} ~=~ \cfrac{1}{6} \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{1}=\stackrel{m}{ \cfrac{1}{6}}(x-\stackrel{x_1}{1}) \\\\\\ y-1=\cfrac{1}{6}x-\cfrac{1}{6}\implies y=\cfrac{1}{6}x-\cfrac{1}{6}+1\implies {\Large \begin{array}{llll} y=\cfrac{1}{6}x+\cfrac{5}{6} \end{array}}[/tex]

a. The y-intercept of the line is 4.

b. The gradient of the line is 2.

The range of possible values for x is approximately -14.7 to 14.7. However, since x represents a length, it cannot be negative. Thus, the range of possible values for x is approximately 0 to 14.7.

The range refers to the difference between the maximum and minimum values in a dataset.
The range is easy to calculate and provides a quick estimate of how much variation there is in the dataset.

We have:

∠ABC + ∠ABD + ∠BDA + ∠BAC = 360°

120° + 115° + ∠BDA + ∠BAC = 360° (substituting given values)

∠BDA + ∠BAC = 125°

Now, we can use the law of cosines to relate the sides and angles in each triangle:

AC² = AB² + BC² - 2ABBCcos(∠ABC)

(4x-10)² = AB² + 24² - 2AB24cos(120°)

(4x-10)² = AB² + 576 + 24AB

AD² = AB² + BD² - 2ABBDcos(∠ABD)

40² = AB² + 24² - 2AB24cos(115°)

AB² - 48AB + 496 = 0

Using the quadratic formula to solve for AB, we get:

AB = (48 ± √(48² - 4×496))/2

AB = 24 ± 2√211

Since AB = 24 + 2x, we have:

24 + 2x = 24 + 2√211 or 24 - 2√211

By Solving for x in each case, we get:

x = √211 + 0.5 ≈ 14.7 or x = -√211 + 0.5 ≈ -14.7

Answer:

[tex]P(x)=3x^4-11x^3+71x^2-275x-100[/tex]

Step-by-step explanation:

Given information:

For any complex number  [tex]z=a+bi[/tex], the complex conjugate of the number is defined as  [tex]z*=a-bi[/tex].  

If f(z) is a polynomial with real coefficients, and z₁ is a root of f(z)=0, then its complex conjugate z₁* is also a root of f(z)=0.

Therefore, if P(x) is a polynomial with real coefficients, and 5i is a root of P(x)=0, then its complex conjugate -5i is also a root of P(x)=0.

So the zeros of the function are: 5i, -5i, 4, and -1/3.

The zeros of a function P(x) are the x-values of the function such that the P(x)=0.  According to the Factor Theorem, if P(x) is a polynomial, and P(a)=0, then (x - a)  is a factor of P(x).

Therefore, the factors of the function are:

[tex]x=5i \implies (x-5i)[/tex]

[tex]x=-5i \implies (x+5i)[/tex]

[tex]x=4 \implies (x-4)[/tex]

[tex]x=-\dfrac{1}{3} \implies (3x+1)[/tex]

So the polynomial in factored form is:

[tex]P(x)=a(x-5i)(x+5i)(x-4)(3x+1)[/tex]

As we have not been given a specific leading coefficient, let us assume it is one.

[tex]P(x)=(x-5i)(x+5i)(x-4)(3x+1)[/tex]

To write the polynomial in standard form, expand and simplify.

[tex]\begin{aligned}P(x)&=(x-5i)(x+5i)(x-4)(3x+1)\\&=(x^2+5ix-5ix-25i^2)(3x^2+x-12x-4)\\&=(x^2-25(-1))(3x^2-11x-4)\\&=(x^2+25)(3x^2-11x-4)\\&=3x^4-11x^3-4x^2+75x^2-275x-100\\&=3x^4-11x^3+71x^2-275x-100\end{aligned}[/tex]

To find the median of the data, we need to first arrange the numbers in order from smallest to largest:

65, 65, 124, 129, 180, 190, 228, 285, 285, 316, 370, 370

There are 12 numbers in the sample, so the median will be the middle value. In this case, there are two middle values because there are an even number of data points. To find the median, we take the average of the two middle values:

median = (180 + 190)/2 = 185

So the median number of pieces in the sample of building toys is 185.

The equation solved for the variable x is:

[tex]x = e^{ W(ln(y))}[/tex]

In any equation of the form:

y = f(x), to make x the subject of the equation, we need to isolate x in one of the sides of the equation, then we will get:

x = g(y).

In this case we have:

xˣ = y

And we want to make x the subject of the equation.

We can start by apliying the natural logarithm in both sides to get:

ln(xˣ ) = ln(y)

x*ln(x) = ln(y)

We can rewrite:

[tex]x = e^{ln(x)}[/tex]

Then our equation becomes:

[tex]e^{ln(x)}*ln(x) = ln(y)[/tex]

Now the Lambert W function is defined as:

[tex]W(x*e^x) = x[/tex]

So if we apply this in both sides, we will get:

[tex]W(e^{ln(x)}*ln(x)) = W(ln(y))\\ln(x) = W(ln(y))[/tex]

Now apply the exponential in both sides and get:

[tex]ln(x) = W(ln(y))\\\\e^{ln(x)} = e^{ W(ln(y))}\\x = e^{ W(ln(y))}[/tex]

That is the equation solved for x.

The answer of the given question on the listing the critical numbers is  the critical numbers as x = 3, 6, and 9. and the function has an absolute maximum at x = 9. and the function has an absolute minimum at x = 2.

an absolute maximum occurs at the highest point on the graph of a function over its entire domain. It can be a local maximum or a global maximum, depending on whether there are any other points in the domain that have higher function values. Finding the absolute maximum of a function is important in optimization problems, where we want to find the maximum or minimum value of a function subject to certain constraints.

Based on the graph provided, we can approximate the critical numbers as x = 3, 6, and 9.

To determine whether there is relative maximum, relative minimum, absolute maximum, or absolute minimum at each critical number, we need to examine  behavior of function near each critical number.

At x = 3, the function has a relative maximum, since the graph changes from increasing to decreasing at that point.

At x = 6, the function has a relative minimum, since the graph changes from decreasing to increasing at that point.

At x = 9, the function has a relative maximum, since the graph changes from increasing to decreasing at that point.

Since the graph increases without bound as x approaches 10 from the left, but approaches a finite value as x approaches 10 from the right, the function has an absolute maximum at x = 9.

Since the graph decreases without bound as x approaches 2 from the right, but approaches a finite value as x approaches 2 from the left, the function has an absolute minimum at x = 2.
