Find two positive numbers whose product is 36 and whose sum is a minimum.
To find two positive numbers whose product is 36 and whose sum is a minimum, set up an equation using the arithmetic mean and geometric mean inequality. Solve for the two numbers.
Explanation:To find two positive numbers whose product is 36 and whose sum is a minimum, we can use the concept of the arithmetic mean and geometric mean inequality. Let the two numbers be x and y. Since the product of the numbers is 36, we have xy = 36. Using the arithmetic mean and geometric mean inequality, we know that the minimum value of the sum of two positive numbers is attained when the two numbers are equal. Therefore, x = y. Substituting this into the equation xy = 36, we have x^2 = 36. Taking the square root of both sides, we get x = √36 = 6. So, the two positive numbers are x = 6 and y = 6.

Explanation:To find two positive numbers whose product is 36 and whose sum is a minimum, we can use the concept of the Arithmetic Mean-Geometric Mean Inequality.
Let x and y be the two numbers.
According to the inequality, the minimum sum occurs when the numbers are equal.
So, we have x = y = √36 = 6.
Therefore, the two positive numbers whose product is 36 and whose sum is a minimum are 6 and 6.

which set of ordered pairs in the form of x y does NOT represent a function of x?
A. {(1, 1.5), (2, 1.5), (3, 1.5), (4, 1.5)}
B. {(0, 1.5), (3, 2.5), (1, 3.3), (1, 4.5)}
C. {(1, 1.5), (-1, 1.5), (2, 2.5), (-2, 2.5)}
D. {(1, 1.5), (-1, -1.5), (2, 2.5), (-2, 2.5)}
A function is a relationship that maps elements from one set (the inputs) into elements of another set (the outputs). Such that each input can be mapped into only one output.
The correct option is B: {(0, 1.5), (3, 2.5), (1, 3.3), (1, 4.5)}
Using the general definition, to find which set of ordered pairs does not represent a function, we need to see in which set we have the same input (the first element of the ordered pair) assigned to two different outputs (the second element of the ordered pair).
Here the one that does not represent a function is option B:
{(0, 1.5), (3, 2.5), (1, 3.3), (1, 4.5)}
Because we have the input x = 1 assigned to two different outputs, y = 3.3 and y = 4.5

Which of the following is a solution to the inequality y > –2x + 6? a.(4, 4) b.(0, 0) c.(1, 1) d.(2, 2)
The correct answer is a.(4, 4) because when you substitute x = 4 and y = 4 into the inequality y > -2x + 6, the inequality holds true, indicating that (4, 4) is a solution.
To determine which of the given points is a solution to the inequality y >
-2x + 6, we substitute the x and y values of each point into the inequality and check if the inequality holds true.
Therefore, the correct answer is a.(4, 4), since it is the only point that satisfies the inequality y > -2x + 6.

An investment grows by 20% over a 20 year period. What is its effective annual percent growth rate?
The effective annual percent growth rate is 3.97%.
Explanation:The effective annual percent growth rate can be calculated using the formula:
Effective Annual Growth Rate = (1 + Growth Rate)^(1/n) - 1
Given that the investment grows by 20% over a 20-year period, the growth rate would be 0.20.
Substituting the values into the formula:
Effective Annual Growth Rate = (1 + 0.20)^(1/20) - 1
Simplifying further:
Effective Annual Growth Rate = (1.20)^(0.05) - 1
Effective Annual Growth Rate = 0.0397 or 3.97%
Final answer:
The effective annual percent growth rate for an investment that grows by 20% over a 20-year period is approximately 0.949%.
Explanation:
To calculate the effective annual percent growth rate, we need to use the formula for compound interest:
A = P(1 + r)^n
where:
A is the amount of money accumulated after n years, including interest.P is the principal amount (the initial amount of money).r is the annual interest rate (decimal).n is the number of years the money is invested for.We can rearrange this formula to solve for r:
r = (A/P)^(1/n) - 1
Given that the investment grows by 20% over 20 years, this means A = 1.20P, as it has increased by 20%. With P as the original amount and n as 20 years, the calculation is:
r = (1.20)^(1/20) - 1
Now we compute the value:
r = (1.20)^(0.05) - 1
r ≈ 0.00949
Converting this into a percentage:
r ≈ 0.949%
Therefore, the effective annual percent growth rate is approximately 0.949%.
What is the slope of the line whose equation is 12=4x−6y ? Enter your answer in the box.
Answer:
Slope of the line 12=4x−6y is [tex]\frac{2}{3}[/tex] .
Step-by-step explanation:
The slope line form is denoted by
y = mx + c
Where m is the slope and c is the y- intercept .
As given
The equation of the line is given by .
12=4x−6y
It is also written as
6y = 4x - 12
[tex]y = \frac{4x}{6} -\frac{12}{6}[/tex]
Simplify the above
[tex]y = \frac{2x}{3} -2[/tex]
(Compare with y = mx + c )
Thus
[tex]m = \frac{2}{3}[/tex]
Therefore the slope of the line 12=4x−6y is [tex]\frac{2}{3}[/tex] .

It takes to sell A three hours to produce two cells.If you start with cell A,how many cells will you have in 24 hours
In 24 hours, you will have 48 cells if you start with cell A and keep making cells at the same rate.
If it takes three hours to produce two cells, we can calculate the production rate as follows:
Production rate of A = 2 cells / 3 hours
Now, we want to find out how many cells will be produced in 24 hours:
Number of cells produced in 24 hours = Production rate of A × Number of hours
Number of cells produced in 24 hours = (2 cells / 3 hours) × 24 hours
Number of cells produced in 24 hours = 2 cells/hour × 24 hours
Number of cells produced in 24 hours = 48 cells
Therefore, if you start with cell A and continue producing at the same rate, you will have 48 cells in 24 hours.

The sum of the squares of two consecutive odd integers is 1570. find the integers
Final answer:
Two consecutive odd integers whose squares sum to 1570 are found by setting up a quadratic equation. Solving this equation gives us 27 and 29 as the required integers.
Explanation:
The question requires us to find two consecutive odd integers whose squares add up to 1570. Let's consider the smaller integer to be n, which means the next consecutive odd integer would be n + 2 (since there is always a difference of 2 between consecutive odd numbers). Our equation based on the given information will be:
[tex]n^2 + (n + 2)^2[/tex] = 1570
To solve for n, we will expand the equation and simplify:
[tex]n^2 + n^2 + 4n + 4[/tex] = 1570[tex]2n^2 + 4n + 4[/tex] = 1570[tex]2n^2 + 4n - 1566[/tex] = 0Divide the entire equation by 2: n2 + 2n - 783 = 0Solving the quadratic equation, we find that n = 27 and n = -29.
As we are looking for positive integers, we take n = 27. Therefore, the two consecutive odd integers are 27 and 29.

What is the relationship between the “solution” to a quadratic equation and the graph of a quadratic equation? How many possible real solutions might there be when you solve a quadratic equation and how do these possible solutions affect the position the parabola on a coordinate plane?
Solutions of a quadratic equation represent points where the graph of the equation (a parabola) intersects the x-axis, and there could be zero, one, or two real solutions.
Explanation:The relationship between the 'solution' of a quadratic equation and the graph of a quadratic equation is that the solutions of a quadratic equation correspond to the points where the graph of this equation, also known as a parabola, intersects with the x-axis on a two-dimensional (x-y) graph. A quadratic equation can have zero, one, or two real solutions. These solutions are represented graphically by where the curve of the parabola intersects the x-axis.
When the parabola intersects the x-axis twice, there are two distinct real solutions. If the parabola is tangent to the x-axis, then there is exactly one real solution, also known as a repeated root, whereas if the parabola does not intersect or touch x-axis at all, then there are no real solutions, indicating that the roots are complex or imaginary.
