Using mathematical operations, the number of balloons that Masha bought for the party was 100, made up of red, green, and yellow balloons.

Mathematical operation includes the use of basic math operators, including addition, subtraction, division, and multiplication to determine and express mathematical values.

Red balloons = 40 balloons

Green balloons = 3/5 (40) = 24 balloons

Green balloons = 24 = 2/3 of yellow balloons

Yellow balloons = 24÷ 2/3 = 24 x 3/2 = 36 balloons

Total ballons bought:

Red = 40

Green = 24

Yellow = 36

Total = 100 (40 + 24 + 36)

Thus, using mathematical operations, the total number of balloons that Masha bought for the party was 100 balloons.

For a function to have an inverse, it must be one-to-one_. To define the inverse sine function, we restrict the domain of the sine function to the interval [-pi, pi].

Two functions f(x) and g(x) are inverses if:

f(x) = y

g(y) = x

This means that the two functions need to be one-to-one, because if there are two values of x such that:

f(x₁) = y = f(x₂)

f(x) can't have an inverse because g(y) would give two different outputs, and then g(x) is not a function.

For the case of the sine (and all periodic functions) we restrict to the region where the function is one to one, which can be any interval of 2 pi radians (the common example is the interval [-pi, pi])

Mr. Arnett will pay $207 for all the trail mix bought by his children.

Here, we are given that Mr. Arnett allowed each of his children to fill their own bag as follows-

Child                 Ava   Grayson   Mason   Tyler

Amount of

Trail Mix (oz)      15        14            10            7

Further, cost of trail mix = $4.50 per pound

The total amount of trail mix collected by all 4 children will be-

15 + 14 + 10 + 7

= 46

Thus, in total the children put 46 pounds of trail mix in their bags.

Hence, the total cost will be-

46 × 4.5

= 207

Thus, Mr. Arnett will pay $207 for all the trail mix.

Answer:

6.08units

Step-by-step explanation:

The distance between two points of a line is expressed as;

D = √(y2-y1)²+(x2-x1)²

Given the coordinates  (3, -5) and (4, 1);

D = √(1+5)²+(4-3)²

D = √(6)²+(1)²

D = √36+1

D = √37

D = 6.08 units

Hence its length is 6.08units

Answer:

bottom is 7.8 gallons left

16-8.2=7.8

To write the equation of the line, we will use the point-slope formula.

To do this, we need a point and a slope.

We can find out slope by using the slope formula.

m = y₂ - y₁ / x₂ - x₁

So we have 5 - 9 / 3 - 1 or -4/2 which is -2.

Now let's use the point-slope formula.

y - y₁ = m(x - x₁)

Now substitute one of our points (x₁, y₁) into our formula.

So we have y - 5 = -2(x - 3).

Distributing the -2 gives us y - 5 = -2x + 6.

Moving the -5 to the right, we have y = -2x + 11.

So y = -2x + 11 is our equation.

Substitute [tex]x=1-y[/tex] and [tex]dx=-dy[/tex].

[tex]\displaystyle \int_0^{1/2} \frac{\ln^2(1-x)}x \, dx = \int_{1/2}^1 \frac{\ln^2(y)}{1-y} \, dy[/tex]

Since [tex]|y|<1[/tex], we can expand into a power series and interchange the integral with the sum.

[tex]\displaystyle \int_{1/2}^1 \frac{\ln^2(y)}{1-y} \, dy = \int_{1/2}^1 \ln^2(y) \sum_{n=0}^\infty y^n \, dy \\\\ ~~~~~~~~~~~~~~~~~~~ = \sum_{n=0}^\infty \int_{1/2}^1 y^n \ln^2(y) \, dy[/tex]

Let

[tex]\displaystyle I_n = \int_{1/2}^1 y^n \ln^2(y) \, dy[/tex]

Integrate by parts with

[tex]u=\ln^2(y) \implies du = \dfrac{2\ln(y)}y \, dy[/tex]

[tex]dv = y^n\,dy \implies v = \dfrac{y^{n+1}}{n+1}[/tex]

[tex]\implies \displaystyle I_n = -\frac{\left(\frac12\right)^{n+1} \ln^2\left(\frac12\right)}{n+1} - \frac2{n+1} \int_{1/2}^1 y^n \ln(y) \, dy[/tex]

Integrate by parts again, now with

[tex]u = \ln(y) \implies du = \dfrac{dy}y[/tex]

[tex]dv = y^n \, dy \implies v = \dfrac{y^{n+1}}{n+1}[/tex]

[tex]\implies \displaystyle I_n = -\frac{\ln^2(2)}{2^{n+1}(n+1)} - \frac2{n+1} \left(-\frac{\left(\frac12\right)^{n+1}\ln\left(\frac12\right)}{n+1} - \frac1{n+1} \int_{1/2}^1 y^n \, dy\right) \\\\ ~~~~~~~~~~~ = \frac2{(n+1)^3} - \frac{\ln^2(2)}{2^{n+1}(n+1)} - \frac{\ln(2)}{2^n (n+1)^2} - \frac1{2^n (n+1)^3}[/tex]

Taking the sum over all [tex]n[/tex] gives

[tex]\displaystyle \int_0^{1/2} \frac{\ln^2(1-x)}x \, dx = \sum_{n=0}^\infty I_n \\\\ ~~~~~~~~ = \sum_{n=0}^\infty \left(\frac2{(n+1)^3} - \frac{\ln^2(2)}{2^{n+1}(n+1)} - \frac{\ln(2)}{2^n (n+1)^2} - \frac1{2^n (n+1)^3}\right) \\\\ ~~~~~~~~ = 2 \sum_{n=1}^\infty \frac1{n^3} - \ln^2(2) \sum_{n=1}^\infty \frac1{2^n n}-2\ln(2)\sum_{n=1}^\infty \frac1{2^n n^2}- 2 \sum_{n=1}^\infty \frac1{2^n n^3}[/tex]

Now recall the definition of the so-called polylogarithm function, given by

[tex]\displaystyle \mathrm{Li}_\nu(z) = \sum_{n=1}^\infty \frac{z^n}{n^\nu}[/tex]

which immediately gives us a "closed" form for the integral of

[tex]\displaystyle \int_0^{1/2} \frac{\ln^2(1-x)}x \, dx \\\\ ~~~~~~~~ = 2\,\mathrm{Li}_0(1) - \ln^2(2)\,\mathrm{Li}_1\left(\frac12\right) - 2\ln(2)\,\mathrm{Li}_2\left(\frac12\right) - 2\,\mathrm{Li}_3\left(\frac12\right)[/tex]

But we can do better. The first sum is [tex]2\zeta(3)[/tex] (by definition of Riemann zeta) and the second is [tex]\ln^2(2)\cdot\ln(2)=\ln^3(2)[/tex] (using the series expansion of [tex]\ln(1+x)[/tex]). The other two polylogs have exact values of

[tex]\displaystyle \mathrm{Li}_2\left(\frac12\right) = \frac{\pi^2}{12} - \frac12 \ln^2(2) \\\\ \mathrm{Li}_3\left(\frac12\right) = \frac{\ln^3(2)}6 - \frac{\pi^2}{12} \ln(2) + \frac78 \zeta(3)[/tex]

(according to what I found when searching "polylogarithm at half integers"). Putting all the results together, we end up with

[tex]\displaystyle \int_0^{1/2} \frac{\ln^2(1-x)}x \, dx = \boxed{\frac{\ln^3(2)}3 + \frac74 \zeta(3)}[/tex]
