Yes, 10 can be replaced by a smaller number. Let's prove it first, then look for a smaller number of people.

Let us write the ages of these 10 people as a1, a2, a3, ... a10.According to the given statement,1 ≤ ai ≤ 60Thus, the age of every individual must be between 1 and 60.

Arrange these ages in a non-decreasing order.

Let's assume that no two groups can have the same sum of ages. Each group has either odd or even numbers of members. Hence, if there are an even number of members in the group, the sum of their ages will also be even. If the group has an odd number of members, the sum of their ages will also be odd.

This means that the 10 people can be divided into five groups, with the sum of the ages of each group being odd or even.

Let us consider two cases:

Case 1:

All five groups have odd sums. This implies that each group has an odd number of members, and the number of members in the group is either 1, 3, or 5. Since there are only 10 people, it is impossible to have five groups with an odd sum of ages. This is because there must be two groups that have the same sum of ages.

Case 2:

Three groups have an even sum, and two groups have an odd sum. This implies that there are two groups with an even number of members and three groups with an odd number of members. Since the ages of each individual are between 1 and 60, the sum of the ages of the members of the group with the most members must be at least 1 + 2 + 3 + 4 + 5 = 15.

Similarly, the sum of the ages of the members of the group with the least members must be at least 1 + 2 = 3. If we remove the members of the two smallest groups, we will be left with 6 members whose ages add up to at least 15 + 3 = 18, which is an even number.

This implies that the remaining three groups must have even sums, which contradicts our assumption that two groups do not have the same sum of ages. This proves that we can always find two groups of people (with no common person) the sum of whose ages is the same. The number 10 can be replaced with a smaller number, for example, 8.

Aaron's taxable income is negative (-$10,100), it means that he does not have any taxable income.

To determine the amount of taxable income for Aaron Rentz in 2020, we need to consider his wages, interest income, and any deductions or credits he may be eligible for.

From the given information, Aaron has $900 of wages and $1,400 of interest income.

In 2020, the standard deduction for a single individual was $12,400. Since Aaron is a qualifying child of his parents, he may not be able to claim his own personal exemption.

To calculate Aaron's taxable income, we subtract the standard deduction from his total income:

Taxable Income = Total Income - Standard Deduction

Taxable Income = $900 + $1,400 - $12,400

Taxable Income = $2,300 - $12,400

Taxable Income = -$10,100

Since Aaron's taxable income is negative (-$10,100), it means that he does not have any taxable income.

The vector equation for the curve C traced out by r(1) = 31i + (6t − 1)j + 4rk, 0 ≤ 1 < 2, using arc length s as the parameter is r(s) = (31/2)s i + [(3/2)s^2 - (1/2)s + 1] j + (2/√3)s k, where a < s.

To express C as a vector function r(s), we need to find an expression for s(t), the arc length of the curve from 0 to t. The arc length s(t) can be calculated by integrating the magnitude of the velocity vector r'(t) over the interval [0, t].

Given the initial point r(1) = 31i + (6t − 1)j + 4rk, we can find the magnitude of the velocity vector r'(t) as |r'(t)| = √(31^2 + (6)^2 + 4^2) = √(31^2 + 36 + 16) = √1293.

Now, we integrate |r'(t)| with respect to t from 1 to t to obtain the expression for s(t): s(t) = ∫[from 1 to t] √1293 dt = (31/2)(t-1).

Finally, we substitute s(t) into the original vector equation r(t) to obtain the vector equation in terms of s: r(s) = r(t) = 31/2 * s i + (3/2) * s^2 j - (1/2) * s j + 4 * (√3/2) * s k.

Thus, the vector equation for the curve C traced out by r(1), 0 ≤ t < 2, using arc length s as the parameter is r(s) = (31/2)s i + [(3/2)s^2 - (1/2)s + 1] j + (2/√3)s k, where a < s.

The equation of the parabola will be:

Step-by-step explanation:

The vertex  (h, k)  is halfway between the directrix and focus.

Find the  x  coordinate of the vertex using the formula

x = (x-coordinate of focus + directrix)/2

 = (3-3)/2

 = 0/2

 =0

The  y -coordinate will be the same as the y-coordinate of the focus.

so the vertex will be: (0, 0)

Finding the distance from the focus to the vertex

The distance from the focus to the vertex and from the vertex to the directrix is |p|.

Subtract the  x  coordinate of the vertex from the x -coordinate of the focus to find  p .

\(p=3-0\)

\(p=3\)

Substitute in the known values for the variables into the equation

The bakery sold total 200 cupcake in that day.

The word percent means per hundred and percent value of a quantity refers to the hundred parts of that quantity. Percent value is expressed by sign %.

In order to determine a percent value of a quantity, we divide the quantity by the total quantity and finally the resultant value is multiplied by 100.

In the other hand, when we need to calculate total quantity from a percentage value, we multiply the specific quantity by 100 and finally the resultant is divided by the percentage value.

Given, Number of cupcakes sold at a specific time =26 which was 13 percent of total number of cupcakes sold in that day.

Therefore, number of total cupcakes sold in that day = 26× 100/13 =200

Step-by-step explanation:

A price markdown is a reduction that is deliberate when selling a product. From the question, we are informed that a video game that usually costs $30.65 is marked down 60%.

The find the new price of the video game, we have to subtract the amount reduced from the original price. The amount reduced is:

= 60% of $30.65

= 60/100 × $30.65

= 0.6 × $30.65

= $18.39

The new selling price = $30.65 - $18.39

= $12.26

The error that Kelvin made when he determined that the new price of the game would be $18.39 was that he didn't subtract the value from the original price of the video game.

The solution to the given differential equation is y(t) = -1/2e^t + 2te^t + 1/2 + δ(t-2), where δ(t) is the Dirac delta function.

To solve the given differential equation, we will first find the complementary solution, which satisfies the homogeneous equation y'' - 2y' + 5y = 0. Then we will find the particular solution for the inhomogeneous equation y'' - 2y' + 5y = 1 + t + δ(t-2).

Step 1: Finding the complementary solution

The characteristic equation associated with the homogeneous equation is r^2 - 2r + 5 = 0. Solving this quadratic equation, we find two complex conjugate roots: r = 1 ± 2i.

The complementary solution is of the form y_c(t) = e^rt(Acos(2t) + Bsin(2t)), where A and B are constants to be determined using the initial conditions.

Applying the initial conditions y(0) = 0 and y'(0) = 4, we find:

y_c(0) = A = 0 (from y(0) = 0)

y'_c(0) = r(Acos(0) + Bsin(0)) + e^rt(-2Asin(0) + 2Bcos(0)) = 4 (from y'(0) = 4)

Simplifying the above equation, we get:

rA = 4

-2A + rB = 4

Using the values of r = 1 ± 2i, we can solve these equations to find A and B. Solving them, we find A = 0 and B = -2.

Thus, the complementary solution is y_c(t) = -2te^t sin(2t).

Step 2: Finding the particular solution

To find the particular solution, we consider the inhomogeneous term on the right-hand side of the differential equation: 1 + t + δ(t-2).

For the term 1 + t, we assume a particular solution of the form y_p(t) = At + B. Substituting this into the differential equation, we get:

2A - 2A + 5(At + B) = 1 + t

5At + 5B = 1 + t

Matching the coefficients on both sides, we have 5A = 0 and 5B = 1. Solving these equations, we find A = 0 and B = 1/5.

For the term δ(t-2), we assume a particular solution of the form y_p(t) = Ce^t, where C is a constant. Substituting this into the differential equation, we get:

2Ce^t - 2Ce^t + 5Ce^t = 0

The coefficient of e^t on the left-hand side is zero, so there is no contribution from this term.

Therefore, the particular solution is y_p(t) = At + B + δ(t-2). Plugging in the values we found earlier (A = 0, B = 1/5), we have y_p(t) = 1/5 + δ(t-2).

Step 3: Finding the general solution

The general solution is the sum of the complementary and particular solutions:

y(t) = y_c(t) + y_p(t)

y(t) = -2te^t sin(2t) + 1/5 + δ(t-2)

In summary, the solution to the given differential equation is y(t) = -1/2e^t + 2te^t + 1/2 + δ(t-2).
