Step-by-step explanation:

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] .

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.

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.

The two positive numbers whose product is 36 and whose sum is a minimum are 6 and 6.

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.

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.

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

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:

Solving 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.

The effective annual percent growth rate is 3.97%.

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:

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%.

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.

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.

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.
