Answers

Given data,

Live Fund are selling their holdings at $5,000 per share

Sale price of Live Fund holding = 5000 dollar

To find:

Amount that Live Fund will get if they sell half of their holding in Marks Brothers.

Assume the total number of shares held by Live Fund in Marks Brothers as A

Therefore, half the holdings (or half the number of shares) of Live Fund will be.

                            = A/2

Thus, if each share is valued at  $5000,

Then the total value of the number of shares sold will be as follows,

                             = 5000 × A/2  dollars

                             =  [tex]\frac{5000*A}{2}[/tex] dollars

                             = 2500 A dollars

Hence, Live Fund will receive  $2500 A

solve the linear equation
8-x=26+x

Answers

The solution of the linear equation is x = -9

What is a linear equation?

A linear equation is an equation in which the highest power of the unknown is one.

How to solve a linear equation?

To solve a linear equation, we collect the like terms and them perform operations of addition, subtraction, multiplication and division to simplify the results and get the answer.

How to solve the linear equation?

Since we have 8 - x = 26 + x

To solve the linear equation, we add + x to both sides. So,

8 - x + x = 26 + x + x

8 + 0 = 26 + 2x

8 = 26 + 2x

Next, we subtract 26 from both sides.

8 - 26 = 26 - 26 + 2x

-18 = 0 + 2x

-18 = 2x

Next, we divide both sides by 2. So, we have

2x = -18

x = -18/2

x = -9

So, the solution of the linear equation is x = -9

many liters of the 5% and the 40% solutions should she mix to get the solution
she needs? Write and solve an equation to match the situation.
Equation:

Answers

The liters of the 5% and the 40% solutions that she should mix to get the solution she needs are 5.7 liters and 4.3 liters respectively.

How to illustrate the information?

Let x be the of volume of the 40% solution, then the volume of 5% would be:

10 L = 40% solution volume+ 5% solution volume

10 L= x + 5% solution volume

5% solution volume = 10l-x

Then the volume calculation would be:

10 liter × 20% = x liter × 40% + (10- x) liter × 5% 10l * 20%

= x liter * 35% + 10 liter*5%

x liter *35

= 10l * 20 - 10l *5

= 10l*m × 15x liter

= 10l *15/35

= 4.28 L= 4.3L

The volume of 40% solution= 4.3L

The volume of 5% solution will be:

The answer is 2553=4400i

Step-by-step explanation:

If y(x) is the solution of the differential equation
[tex] \rm{xdy - ( {y}^{2} - 4y)dy = 0 \: for \: x > 0, \: \: \: \: \: \: \: y(1) = 2,}[/tex]
& the slope of the curve y=y(x) is never zero, then the value of [tex]\rm{10y( \sqrt{2} )}[/tex] is​

Answers

I assume the equation is

[tex]x \, dy - (y^2 - 4y) \, dx = 0[/tex]

since separating variables leads to

[tex]x\,dy = y(y-4) \, dx[/tex]

[tex]\dfrac{dy}{y(y-4)} = \dfrac{dx}x[/tex]

for which the condition that [tex]x>0[/tex] is actually relevant, as opposed to the simpler differential equation

[tex]x \, dx - (y^2-4y)\, dy = 0 \implies y(y-4) \, dy = x \, dx[/tex]

(though it's a bit more work to solve for [tex]y(x)[/tex] in this case)


That the slope [tex]\frac{dy}{dx}[/tex] is non-zero tells us that

[tex]\dfrac{dy}{dx} = \dfrac{y(y-4)}x \neq 0 \implies y\neq0 \text{ and } y \neq 4[/tex]

Integrate both sides.

[tex]\displaystyle \int \frac{dy}{y(y-4)} = \int \frac{dx}x[/tex]

On the left, expand into partial fractions.

[tex]\displaystyle \frac14 \int \left(\frac1{y-4} - \frac1y\right) \, dy = \int \frac{dx}x[/tex]

[tex]\dfrac14 (\ln|y-4| - \ln|y|) = \ln|x| + C[/tex]

With the given initial value, we find

[tex]y(1) = 2 \implies \dfrac14 (\ln|2-4| - \ln|2|) = \ln|1| + C \implies C = 0[/tex]

so the particular solution is

[tex]\dfrac14 (\ln|y-4| - \ln|y|) = \ln|x|[/tex]

By definition of absolute value, with the initial condition of [tex]0 < y=2 < 4[/tex] and the condition [tex]x>0[/tex], we can remove the absolute values.

[tex]\dfrac14 (\ln(4-y) - \ln(y)) = \ln(x)[/tex]

Solve for [tex]y[/tex].

[tex]\ln\left(\dfrac{4-y}y\right) = 4 \ln(x) = \ln\left(x^4\right)[/tex]

[tex]\dfrac{4-y}y = \dfrac4y - 1 = x^4[/tex]

[tex]\implies y(x) = \dfrac4{1 + x^4}[/tex]

Then

[tex]10y\left(\sqrt2\right) = \dfrac{40}{1 + \left(\sqrt2\right)^4} = \boxed{8}[/tex]

On the off-chance you meant the other equation I suggested, we find

[tex]\displaystyle \int y(y-4) \, dy = \int x \, dx[/tex]

[tex]\displaystyle \frac{y^3}3 - 2y^2 = \frac{x^2}2 + C[/tex]

[tex]y(1) = 2 \implies \dfrac83 - 2\cdot4 = \dfrac12 + C \implies C = -\dfrac{35}6[/tex]

Solving for [tex]y(x)[/tex] involves picking the right branch of the cube root that agrees with [tex]y(1)=2[/tex]. With the cube root formula, we find

[tex]y(x) = 2 - \xi(1 - i\sqrt3) - \dfrac1\xi (1+i\sqrt3)[/tex]

where

[tex]\xi = \dfrac{2\sqrt[3]{4}}{\sqrt[3]{3x^2 - 3 + \sqrt{9x^4 - 18x^2 - 1015}}}[/tex]

With a calculator, we find

Population growth is exponential, growing by some multiple over time that is dictated by a rate. To find the population exponential growth formula, take this initial premise, the population multiplied by a rate, and equate it to the change in population with respect to time.

Answers

An equation for the transformation of y = x vertical compression by a factor of 1/11 is; y = (1/11)x

What is vertical compression in transformation?

Vertical compressions in transformations occur when a function is multiplied by a rational scale factor. This means that base of the function's graph would remain unchanged when a graph is compressed vertically because it is only the output values that will be affected.

Now, we are given the equation as; y = x

When it undergoes a vertical compression by a factor of 1/11, we can say that the new equation will be; y = (1/11)x

Thus, we conclude that an equation for the transformation of y=x
