Concentric circle simply means the circle that has a common center or axis.

Your information is incomplete. Therefore, an overview of concentric circles will be given. The region between two concentric circles is known as the annulus.

An example of concentric circle is the ripple that is made when a pebble is dropped inside water. The formula for a concentric circle is given as:

(x - h)² + (y - k)² = r².

In conclusion, when two circles have same center, they're called concentric circles.

The maximum revenue of the craftsman is an illustration of objective function

The craftsman can at most make $500, if he makes 100 bracelets

Represent bracelet with b and necklace with n.

From the question, we have:

                 b              n        Total

Unit           10          20        1000

Time         10           40        1600

Cost         5           7.5

So, we have the objective function to be:

Max C = 5b + 7.5n

And the constraints are:

10b + 20n ≤ 1000

10b + 40n ≤ 1600

b ≥ 0

n ≥ 0

From the given graph of the constraints, we have the following feasible points

(b,n) = (0,0) (40,30) (0,50) and (100,0)

Substitute these values in the objective function

C(0,0) = 5(0) + 7.5(0) = 0

C(40,30) = 5(40) + 7.5(30) = 425

C(0,50) = 5(0) + 7.5(50) = 375

C(100,0) = 5(100) + 7.5(0) = 500

The maximum revenue is at the point (100,0)

Hence, the craftsman can at most make $500, if he makes 100 bracelets

Solve inside the parenthesis first

(9+4) - 2(9-4) = (13) - 2(5)

Distribute the 2 and solve

[tex](x - 2)^{2} + (y + \frac{5}{2} )^{2} = \frac{37}{4}[/tex]

Step-by-step explanation:

The standard form of the equation: (x-2)²+ (y + 5/2)² = 37/4 , center: (2, -5/2) and radius: (√37) / 4.

A circle is a closed, two-dimensional object where every point in the plane is equally spaced from a central point. The line of reflection symmetry is formed by all lines that traverse the circle.

We have given the equation,

2x²+2y²-8x + 10y+2 = 0

Divide by 2,

x²+y²-4x + 5y+1 = 0

Arranging the terms to make a complete square of variable x and y.

x²+y²-4x + (2/2)5y+1+ 4 + 25/4 = 4 + 25/4

(x-2)²+ (y + 5/2)² = 37/4

This is the form of a circle.

Use this form to determine the center and radius of the circle.

(x−h)²+(y−k)²=r²

Match the values in this circle to those of the standard form.

The variable r represents the radius of the circle, h represents the x-offset from the origin, and k represents the y-offset from the origin.

r=(√37) / 4, h=2, k= -5/2

The center of the circle is found at (h,k).

Center: (2, -5/2)

Therefore, center: (2, -5/2), radius: (√37) / 4

The second order polynomial that involves the variable x (border inside the rectangle) and associated to the unshaded area is x² - 62 · x + 232 = 0.

The area of a rectangle (A), in square inches, is equal to the product of its width (w), in inches, and its height (h), in inches. According to the figure, we have two proportional rectangles and we need to derive an expression that describes the value of the unshaded area.

If we know that A = 648 in², w = 22 - x and h = 40 - x, then the expression is derived below:

A = w · h

(22 - x) · (40 - x) = 648

40 · (22 - x) - x · (22 - x) = 648

880 - 40 · x - 22 · x + x² = 648

x² - 62 · x + 232 = 0

Matthew’s, Rhoda’s, and Ming’s are true except the Anyah's statement Hence the correct option is D.

A perfect square is a number system that can be expressed as the

square of a given number from the same system.

1. Anyah states that the square root of 0.89 is between 0.44 and 0.45 because 0.44<0.89/2<0.45.  This statement of anyah is false because the√0.89 = 0.9433.

2. Matthew states that the square root of 0.89 is between 0 and 1 because 0< 0.89<1. the value lies between 0 and 1 So this statement is true.

3. Rhoda states that the square root of 0.89 is between 0.9 and 1.0 because of 0.9^2 <0.89<1.0. This statement is true because the square of 0.9 is 0.81 and 1.0 is 1, and 0.89 lies in between them. So the statement is true.

4. Ming states that the square root of 0.89 is between 0.93 and 0.95 because of 0.93^2 <0.89<0.95^2. this statement is also true.

Step-by-step explanation:

A triangle with side lengths 2 in., 5 in., and 4 in. is an acute triangle Thus, the triangle is not acute because 2² + 4² < 5².

An acute angle is defined as the measure of an angle that is less than 90 degrees.

The square of the hypotenuse of a right triangle with the given sides would be 2² +4² = 20.

So, that hypotenuse would be √20, about 4.47.

The long side of this triangle is longer than that, hence the angle opposite is larger than 90°. The triangle with sides 2, 4, and 5 is an obtuse triangle.

The triangle is not acute because 2² + 4² < 5²
