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.

I believe that this problem has the following choices:

It must be equal to BQ .
It must be wider than when he constructed the arc centered at point A.
It must be equal to AB .
It must be the same as when he constructed the arc centered at point A.

The correct answer is the last one:

It must be the same as when he constructed the arc centered at point A.

Answer:

The compass must be the same width as it was when he constructed the arc from point A.

Step-by-step explanation:

In order to construct a perpendicular line to a given line, we need to construct a point above and a point below the line such that the segment through them meets the line at a right angle.

When he constructed the arc from point A, it gave him one piece to creating these points.  An arc from point B, intersecting the arc from point A at two points, will give him the two points he needs.

In order for the arc from point B to intersect the arc from point A, however, the width of the compass must be the same as it was when he constructed the arc from point A.

This means that all the cars are motor vehicles but converse need not be true.

i.e. all the motor vehicles cant be cars.

i.e. Cars are contained in Motor Vehicles.

Hence, the correct Venn diagram is:  Option: a

(  Option: b represent the statement

Some cars are  Motor vehicles and some motor vehicles are cars.

Option: c represent the statement

Answer: 7 units

Step-by-step explanation: In this problem, the given numbers -3 and 4 represent the coordinates of the endpoints of a segment and we are asked to find the length of the segment.

To find the length of a segment, we take the greater endpoint coordinate minus the lesser endpoint coordinate.

In this case, the greater endpoint coordinate is 4 and the lesser endpoint coordinate is -3.

So, we have 4 - (-3) which can also be thought of as 4 + 3 which equals 7.

Therefore, the length of this segment is 7 units.

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%.

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.

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.
