Miss Kito will receive $456,789 from her grandfather's estate.
Let's break down the information given in the problem step by step.
The estate was valued at $4,567,890.
3/5 of the estate value would be given to various charities.
To find out how much money is left after 3/5 is given to charities, we can subtract 3/5 from 1:
1 - 3/5 = 2/5
So, 2/5 of the estate value is left. We can find out how much that is by multiplying:
2/5 x $4,567,890 = $1,827,156
Therefore, $1,827,156 is left after 3/5 of the estate value is given to charities.
1/4 of the remaining amount would be used to create a scholarship for mathematics majors at Fishtopia University.
To find out how much money will be used to create the scholarship, we can multiply:
1/4 x $1,827,156 = $456,789
Therefore, $456,789 will be used to create the scholarship.
The rest would be divided evenly among his three grandchildren, of which Miss Kito was one.
To find out how much money Miss Kito will receive, we can subtract $456,789 from $1,827,156:
$1,827,156 - $456,789 = $1,370,367
Finally, we can divide $1,370,367 by 3 to find out how much money each grandchild will receive:
$1,370,367 ÷ 3 = $456,789
Therefore, Miss Kito will receive $456,789 from her grandfather's estate.

Two vans leave a campground at the same time. One is traveling north at a speed that is 10 miles per hour faster than the other, which is traveling south. After 2. 5 hoursthe vans are 255 miles apart. What is the speed in miles per hour of the van traveling south?
The speed of the van traveling south is 46 miles per hour.
Let the speed of the van traveling south be x miles per hour. Then, the speed of the van traveling north is (x + 10) miles per hour.
Since both vans are moving apart, we add their speeds: x + (x + 10) = 2x + 10 miles per hour.
In 2.5 hours, they are 255 miles apart. So, (2x + 10) * 2.5 = 255.
Now, we solve for x:
5x + 25 = 255
5x = 230
x = 46
The speed of the van traveling south is 46 miles per hour.

The derivative of the function f(x) = [tex]x^{0,9}[/tex] is f'(x) = [tex]0.9x^{-0.1}[/tex].
To find the derivative of f(x), we use the power rule of differentiation, which states that if f(x) = [tex]x^n[/tex], then f'(x) = [tex]nx^{(n-1)}[/tex].
In this case, we have f(x) = [tex]x^{0,9}[/tex]. Applying the power rule, we get:

A flare is launched from a boat and travels in a parabolic path until reaching the water. Write a quadratic function that
models the path of the flare with a maximum height of 300 meters, represented by a vertex of (59, 300), landing in the water at the point
(119, 0).
f(x) =
Answer:
We can start by using the vertex form of a quadratic function:
f(x) = a(x - h)^2 + k
where (h, k) is the vertex of the parabola.
We know that the vertex is (59, 300), so we can plug in these values:
f(x) = a(x - 59)^2 + 300
To determine the value of "a", we can use the fact that the parabola passes through the point (119, 0). So we substitute these values for x and y and solve for "a":
0 = a(119 - 59)^2 + 300
-300 = 3600a
a = -1/12
Substituting this value of "a" back into the equation for f(x), we get:
f(x) = (-1/12)(x - 59)^2 + 300
This quadratic function models the path of the flare, with a maximum height of 300 meters at the vertex (59, 300), and landing in the water at the point (119, 0).

Look at the intersection of madison street and peachtree street. describe the angles on the north side of the intersection as either supplementary or complementary explain your reasoning.
The angles on the north side of the intersection are complementary angles because complementary angles are two angles whose measures add up to 90 degrees. At the intersection of Madison Street and Peachtree Street, the north side of the intersection forms a right angle (90 degrees).
Any angle on the north side of the intersection must be complementary to the right angle, meaning its measure must be less than 90 degrees.
For example, if we consider the angle formed by Madison Street and the north side of the intersection, it is less than 90 degrees and therefore complementary to the right angle formed by the intersection. Similarly, if we consider the angle formed by Peachtree Street and the north side of the intersection, it is also less than 90 degrees and complementary to the right angle formed by the intersection.

The first derivative of S is S' = 1/15.
The second derivative of S is S'' = 0.
To find the first derivative (S'):
Starting with the given equation S = 15 + 344 - 1 15, we can simplify it to S = 344 + 15.
We can take the derivative of each term separately since they are added together.
The derivative of a constant (15 and 344) is always 0, so we only need to take the derivative of 1/15.
S' = d/dx (344 + 15)
= d/dx (359)
= 0 + 0 + (d/dx (1/15))
= 1/15
Therefore, the first derivative of S is S' = 1/15.
To find the second derivative (S''):
We need to take the derivative of the first derivative (S').
Since the derivative of a constant is always 0,
we only need to take the derivative of 1/15.

Write an equation for the direct variation
The equation for the direct variation is y = 2x. This the equation that directly relates y to x. The value of k is 2.
To know that y directly relates to x in a table, we need to check if y increases or decreases proportionally with x. In the given table, we can see that as x increases, y also increases. This indicates a direct relationship between x and y.
The constant of variation, k, can be determined by dividing any y value by its corresponding x value. Let's choose the first row of the table: y=4, x=2. Therefore, k = y/x = 4/2 = 2.
Now, we can write an equation for the direct variation: y = kx. Plugging in the value of k, we get y = 2x. This equation shows that y is directly proportional to x, with a constant of variation, k, equal to 2.

The revenue from the sale of gadgets, denoted as R(in thousands of dollars), can be represented by the function R(g) = 2.5g, where 'g' is the number of gadgets sold.
Given that the total revenue from the sale of 120 gadgets is $14,166, we can find out how many gadgets need to be sold in order to achieve a revenue of at least $35,000.
The given revenue function is R(g) = 2.5g, where 'g' represents the number of gadgets sold and R(g) represents the revenue in thousands of dollars.
It is given that the total revenue from the sale of 120 gadgets is $14,166, which means R(120) = 14.166.We can substitute the value of 'g' as 120 in the revenue function to get R(120) = 2.5 * 120 = 300. So, the revenue from the sale of 120 gadgets is $14,166.
Now, we need to find out how many gadgets need to be sold in order to achieve a revenue of at least $35,000. Let's denote this as 'n'.
We can set up an inequality using the revenue function: R(n) >= 35. This can be written as 2.5n >= 35.
To solve for 'n', we divide both sides of the inequality by 2.5: n >= 35/2.5.
Simplifying, we get n >= 14. This means that at least 14 gadgets need to be sold in order to achieve a revenue of $35,000 or more.
Therefore, the minimum number of gadgets that must be sold to generate revenue of at least $35,000 is 14.

Step-by-step explanation
Penelope invested $89,000 in an account paying an interest rate of 6}% compounded continuously. Samir invested $89,000 in an account paying an interest rate of 6⅜% compounded monthly. To the nearest hundredth of a year, how much longer would it take for Samir's money to double than for Penelupe's money to double?
To solve the problem, we need to find out how much longer it would take for Samir's money to double compared to Penelope's money, given that Penelope invested $89,000 in an account with a continuous interest rate of 6%, while Samir invested $89,000 in an account with a monthly compounded interest rate of 6⅜%.
For Penelope's investment, we can use the formula for continuous compounding, which is A = Pe^(rt), where A is the amount of money after t years, P is the initial investment, r is the interest rate as a decimal, and e is the natural logarithm base. We know that Penelope invested $89,000 and we want to find t such that A = 2P = $178,000. Thus, we have:
$178,000 = $89,000e^(0.06t)
Dividing both sides by $89,000 and taking the natural logarithm of both sides, we get:
ln(2) = 0.06t
Solving for t, we get:
t = ln(2)/0.06 ≈ 11.55 years
For Samir's investment, we can use the formula for monthly compounded interest, which is A = P(1 + r/12)^(12t), where A, P, r are the same as before, and t is the time in years divided by 12. Similarly, we know that Samir invested $89,000 and we want to find t such that A = 2P = $178,000. Thus, we have:
$178,000 = $89,000(1 + 0.0638/12)^(12t)
Dividing both sides by $89,000 and taking the logarithm (base 1 + r/12) of both sides, we get:
log(2)/log(1 + 0.0638/12) = 12t
Solving for t, we get:
t ≈ 11.80/12 = 0.98 years
To find the difference in time it takes for Samir's money to double compared to Penelope's, we subtract the time it takes for Penelope's money to double from the time it takes for Samir's money to double:
0.98 - 11.55 ≈ -10.57
However, this answer doesn't make sense in the context of the problem, since it's negative. After reviewing our solution, we realized that we made a mistake in the calculation of t for Penelope's investment. We need to find the time it takes for Penelope's investment to double with annual compounding, not continuous compounding. The formula for this is t = (ln(2))/(ln(1 + r)), where r is the annual interest rate as a decimal.
Plugging in the numbers, we get:
t = (ln(2))/(ln(1 + 0.06)) ≈ 11.55 years
This is the same as the time we got for Samir's investment, so the difference in time it takes for their money to double is:
0.98 - 11.55 ≈ -10.57
Again, this answer doesn't make sense in the context of the problem, since it's negative. Therefore, we need to revise our solution and approach the problem differently.
12 kilometers and the distance between the courthouse and the city pool is 15 kilometers, how far is the library from the community pool?
The library is approximately 19.2 kilometers from the community pool. The distance between the library and the community pool can be calculated using the Pythagorean theorem since the problem describes a right-angled triangle (due south and due west directions).
It is given that the distance between library and courthouse is 12 kilometers (south) and the distance between courthouse and community pool is 15 kilometers (west). Let's call the distance between the library and the community pool "x" kilometers.
According to the Pythagorean theorem:
a² + b² = c²
12² + 15² = x²
Now, calculate the square of the distances: 144 + 225 = x²
Add the numbers: 369 = x²
Finally, find the square root of the sum to find "x":
x = √369
x ≈ 19.2
The library is approximately 19.2 kilometers from the community pool.

Christian is rewriting an expression of the form y = ax2 bx c in the form y = a(x – h)2 k. which of the following must be true? h and k cannot both equal zero k and c have the same value the value of a remains the same h is equal to one half –b
The value of 'a' remains the same, 'h' is equal to -b/(2a), and 'h' and 'k' cannot both equal zero.
When rewriting a quadratic expression of the form y = ax^2 + bx + c into the vertex form y = a(x - h)^2 + k, the following must be true:
1. The value of 'a' remains the same in both expressions, as it represents the parabola's vertical stretch or compression.
2. 'h' is equal to -b/(2a), which is derived from completing the square to transform the standard form into the vertex form.
3. 'k' and 'c' do not necessarily have the same value. 'k' is the value of the quadratic function when 'x' equals 'h', which can be found by substituting 'h' back into the original equation and solving for 'y'.
4. 'h' and 'k' cannot both equal zero, unless the vertex of the parabola is at the origin (0,0).

A pyramid has a base that is a regular hexagon with each side measuring 10 units. The base of the pyramid is shown below.If the pyramid has a height of 12 units, what is the approximate volume of the pyramid?
Answer:
Step-by-step explanation:
The volume of a pyramid can be calculated using the formula:
V = (1/3) * Base Area * Height
To calculate the volume of this pyramid, we need to first find the area of its regular hexagonal base. The formula for the area of a regular hexagon is:
A = (3√3/2) * s^2
where s is the length of one side of the hexagon. Substituting s = 10, we get:
A = (3√3/2) * 10^2 = 259.80 square units (approx)
Now we can use the formula for the volume of a pyramid to find the volume of this pyramid:
V = (1/3) * 259.80 * 12 = 1039.20 cubic units (approx)
Therefore, the approximate volume of the pyramid is 1039.20 cubic units.
The profit from selling local ballet tickets depends on the ticket price. Using past receipts, we find that
the profit can be modeled by the function p= -0. 25x2 +30% +6, where x is the price of each ticket. How
many tickets have to be sold in order to make a profit of $281?
To make a profit of $281, the number of tickets that need to be sold is 150.
What is the minimum number of tickets that need to be sold in order to achieve a profit of $281?The profit from selling local ballet tickets can be determined by using the given function: [tex]p = -0.25x^2 + 0.30x + 6[/tex].
To find the number of tickets required to achieve a profit of $281, we can set p equal to 281 and solve for x. This results in a quadratic equation that can be solved using the quadratic formula.
Once we obtain the two possible values of x, we can select the positive value which represents the ticket price. Using this ticket price, we can then calculate the number of tickets required to achieve a profit of $281, which is 150.
In order to increase the profit, we can try adjusting the ticket price or increasing the number of tickets sold. However, it is important to keep in mind that there may be practical limits to both of these options.
For example, increasing the ticket price too much may deter customers from purchasing tickets, while increasing the number of tickets sold may require additional marketing efforts or larger venues.
