The required area of the shaded region is 141.3  sq. in.

A circle's area is the area that it takes up in a two-dimensional plane. It can be simply calculated using the formula A = r2, (Pi r-squared), where r is the circle's radius. The square unit, such as m^2, cm^2, etc., is the unit of area. Area of a circle is equal to r2 or d2/4, where = 22/7 or 3.14.

inner radius = 6 in, outer radius= 9 in

are of small circle = πr^2

Area = π(6)^2 = 36π sq. in

Similarly

Area of big circle = πr^2

Area = π(9)^2 = 81π sq. in

So,

Area of shaded region =  81π - 36π

Area of shaded region = 45π

Area of shaded region = 141.3  sq. in

Thus, required area is 141.3  sq. in.

Out of the 500 homes, 226 Type A forms were sent while 274 Type B forms were sent.

To determine the number of forms sent, we can begin by identifying how much Jeannie spent on mailing each of the questionnaires. The sum of $0.19 and $0.23 is $0.42. Now, we will find out how much of these were the total cost as follows:

Type A:

$0.19 / $0.42 ×  $106.20

= $48.

Type B:

$0.23 / $0.42 ×  $106.20

= $58.2

Next, we will determine how much of these went into the 500 homes as follows:

Type A:

$48 / 106.2 × 500

= 225. 9 ≈ 226 homes

Type B:

$58.2 / $106.2 × 500

= 274 homes

The midpoint method is a numerical integration technique used to approximate the definite integral of a function over a given interval. It is a Riemann sum method.

The line that connects these two places is split in half equally at the halfway. In addition, the halfway is reached if a line is drawn to divide the line that connects these two places. When we know the coordinates of two points, we can apply the midpoint formula to get the midpoint between them.

Here,

The midpoint method is used for a few reasons:

Simplicity: The midpoint method is relatively easy to understand and implement, compared to other numerical integration techniques.

Accuracy: The midpoint method is more accurate than some other Riemann sum methods like the left-hand rule or right-hand rule, which evaluate the function at the endpoints of each subinterval.

Efficiency: The midpoint method is more efficient than some other numerical integration techniques, especially for functions that are not smooth or have sharp changes.

Flexibility: The midpoint method can be used for both definite and indefinite integrals, and for functions that are not well-behaved.

Overall, the midpoint method is a simple, accurate, efficient and flexible numerical integration method that can be used to approximate the definite integral of a function over a given interval.

Yes, dilation is a type of transformation that involves multiplying the coordinates of a figure by a scale factor.

This scale factor can be greater than 1, which is an enlargement, or less than 1, which is a reduction. To calculate the coordinates of a dilation, the following formula is used: (x, y) → (kx, ky), where (x, y) are the coordinates of the original point and (kx, ky) are the coordinates of the transformed point. The scale factor, k, is the same for both the x and y coordinates. For example, if the scale factor is 2 and the original coordinates are (2, 4), the new coordinates would be (4, 8). This means that the point (2, 4) has been enlarged to (4, 8).

When graphing polynomials, we can determine the end behavior by the degree of the polynomial and the coefficient of the leading term.

The degree of a polynomial is the highest exponent of the variable found in the equation. The coefficient of the leading term is the number that is multiplied by the variable in the leading term. The end behavior of a polynomial can be determined by examining the sign of the coefficient and the degree of the polynomial.

For example, let's consider the polynomial equation y = x^3 - 2x^2 + 5x + 7. The degree of this polynomial is 3, and the coefficient of the leading term is 1. This means that the end behavior of this polynomial equation will be increasing, since the coefficient and degree are both positive. To confirm this, we can calculate the limit of the polynomial as x approaches positive and negative infinity. As x approaches positive infinity, the limit of y is positive infinity (∞), and as x approaches negative infinity, the limit of y is also positive infinity (∞). This confirms that the end behavior of this polynomial equation is increasing.

The proper method of finding a value table has been mentioned and explained below.

Value tables are a part of domain definition. The value table is maintained at the domain level and thus, is also called domain-level validation. Whenever you create a domain, you can enter the required values. Whenever you use this Domain, the system will make it so that you are forced to enter only these values. This is a sort of master check.

This means that if you want to enter values into this table you have to create a development request & transport the same. The system, then, proposes the value table as a check table. The check against the value table only takes place when a foreign key is defined

Answer: The diagonal and the height of the right triangle form the legs of the triangle, and the unknown length is the hypotenuse. To find the length of the hypotenuse, we can use the Pythagorean theorem. The theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides (the legs).

So, if the legs of the right triangle measure 12 inches and 15 inches, the hypotenuse c can be calculated as follows:

c² = a² + b²

c² = 12² + 15²

c² = 144 + 225

c² = 369

Therefore, the length of the hypotenuse c is the square root of 369.

c = √369

c = 19.1 inches

Therefore, the top of the spider web is 19.1 inches long.

Given system:

We can solve it by elimination.

Multiply the first equation by 6 and add up to get:

Without solving for x we can see there is one solution.

The last answer choice is the correct one.

Answer:

The given system of equations has exactly one solution (1, ⁴/₃).

Step-by-step explanation:

Given system of equations:

[tex]\begin{cases}-x+6y=7\\6x-30y=-34\end{cases}[/tex]

To solve the given system of equations, multiply all terms of the first equation by 5:

[tex]\implies -x \cdot 5+6y \cdot 5=7 \cdot 5[/tex]

[tex]\implies -5x+30y=35[/tex]

Add this to the second equation to eliminate the term in y:

[tex]\begin{array}{crcccl}&6x & - & 30y & = &-34\\\vphantom{\dfrac12}+ & (-5x & + & 30y & = & \;\;\:35)\\\cline{2-6}\vphantom{\dfrac12}&x&&&=&\;\;\;\;\:1\\\cline{2-6}\end{array}[/tex]

Therefore, x = 1.

Substitute the found value of x into the first equation and solve for y:

[tex]\implies -(1)+6y=7[/tex]

[tex]\implies 6y=8[/tex]

[tex]\implies y=\dfrac{8}{6}[/tex]

[tex]\implies y=\dfrac{4}{3}[/tex]

Therefore, the given system of equations has exactly one solution (1, ⁴/₃).

the solution of equation  y=x+2 and  y=3x-2 are x= 2 and y=4

y = x+2 ------------ equation 1

y = 3x -2 ------------ equation 2

in the first equation y = x +2

in the second equation y = 3x -2

this mean equation 1 = equation 2

then we can equate the two together to get one of the variable

remember, we have to unknown variables which are x and y, so we need to isolate y to get x

x + 2 = 3x -2

let collect the like terms

x - 3x = -2 -2

let us factorize out x on the right hand side of the equation

x(1 - 3) = -4

x(-2) = -4

-2x = -4

divide both sides by -2

-2x/-2 = -4/-2

x = 2
