Find two positive numbers such that the sum of the first and twice the second is 100 and their product is a maximum.

let the two numbers be x and y

x + 2y = 100

product = xy
= (100-2y)(y)
= 100y - 2y^2
d(product)/dy = 100 - 4y
= 0

4y = 100
y = 25
x = 100 - 50 = 50

they are 25 and 50

Ah, trying to maximize that product, huh? Well, I'm here to help with a touch of humor! Let's try to find those two numbers that will make your product as big as possible.

Let's call the first number "x" and the second number "y." According to the problem, we have two equations:

1) x + 2y = 100, and
2) maximize the product, which is xy.

Now, solving equation 1) for x, we get x = 100 - 2y. We can substitute this value of x in equation 2) to get the product in terms of y:

Product = (100 - 2y) * y = 100y - 2y^2.

Now, to maximize this quadratic equation, we'll need to put on our mathematical thinking caps. Remember, folks, the highest point of a quadratic equation occurs at the vertex!

So, let's put on that clown wig and find the vertex of the quadratic equation. Mwahaha!

Using the formula for the x-coordinate of the vertex, we get x = -b/(2a). In this case, a = -2 and b = 100, so x = -100/(2*(-2)) = 25.

So, the y-coordinate of the vertex is y = 100y - 2y^2, where y = 25:

Product = 100(25) - 2(25^2) = 2500 - 2(625) = 2500 - 1250 = 1250.

Therefore, the maximum product is 1250.

To summarize, the two positive numbers that will maximize their product are approximately x = 75 and y = 25.

Remember, I'm just a Clown Bot, so take these calculations with a grain of circus salt!

To find two positive numbers that maximize their product, we can use the method of differentiation. Let's assume the two positive numbers as x and y.

Given conditions:
1. The sum of the first number (x) and twice the second number (2y) is 100: x + 2y = 100.
2. We want to maximize the product: P = x * y.

We will first solve the first equation to express x in terms of y and then substitute it into the equation for P. Then, we can differentiate P with respect to y and equate it to zero to find the maximum.

Step 1: Express x in terms of y.
From the equation x + 2y = 100, we can isolate x:
x = 100 - 2y.

Step 2: Substitute x into the equation for P.
P = (100 - 2y) * y.

Step 3: Differentiate P with respect to y.
dP/dy = 100 - 4y.

Step 4: Equate dP/dy to zero to find the maximum.
100 - 4y = 0.
4y = 100.
y = 100/4.
y = 25.

Step 5: Substitute the value of y into the equation for x to find the corresponding x-value.
x = 100 - 2y.
x = 100 - 2(25).
x = 100 - 50.
x = 50.

Therefore, the two positive numbers that maximize their product are x = 50 and y = 25.

To find two positive numbers that satisfy the given conditions and maximize their product, we can use the method of optimization.

Let's consider two positive numbers, x and y. According to the problem statement, the sum of the first number and twice the second number is 100, so we can write the equation:

x + 2y = 100

To maximize the product of two numbers, we can use the concept of AM-GM inequality. According to the inequality, the arithmetic mean of two numbers is always greater than or equal to the geometric mean. Mathematically, this can be expressed as:

(x + 2y) / 2 ≥ √(x * 2y)

Simplifying this inequality, we get:

x + 2y ≥ 2√(2xy)

Since we already know the sum x + 2y = 100, we can substitute it into the inequality:

100 ≥ 2√(2xy)

Next, let's square both sides of the inequality to remove the square root:

100² ≥ 4xy

Simplifying further:

10000 ≥ 4xy

Dividing both sides of the equation by 4, we obtain:

2500 ≥ xy

Therefore, to maximize the product xy, we need to find the largest possible value of xy that is less than or equal to 2500.

We can continue by trying different values of x and y that satisfy the equation x + 2y = 100 and calculate the corresponding value of xy until we find the maximum value. However, to simplify the process, we can observe that the two numbers that maximize the product will be as close as possible to each other.

Let's consider x = 50 and y = 25:
x + 2y = 50 + 2(25) = 100, which satisfies the given equation.

Calculating the product, xy = 50 * 25 = 1250.

Now, let's consider x = 49 and y = 26:
x + 2y = 49 + 2(26) = 101, which is slightly greater than the given sum.

Calculating the product, xy = 49 * 26 = 1274.

We can see that as the numbers get closer to each other, the product increases. It means that the maximum product occurs when the two numbers are closest.

Hence, the two positive numbers that maximize their product while satisfying the given conditions are approximately 49 and 26, respectively.
