The values of the variables x and y for the cyclic quadrilateral are 9 and 17 respectively.

The figure is a cyclic quadrilateral since it four side vertices lie on the circumference of the circle. The sum of the interior angles of a cyclic quadrilateral is also 360°. Also opposite angles of a cyclic quadrilateral add up to 180°

Thus;

11x + 8 + 8x + 1 = 180° {opposite angles of a cyclic quadrilateral}

19x + 9 = 180°

19x = 180° - 9 {collect like terms}

19x = 171

x = 171/19

x = 9

Also;

6y - 4 + 5y - 3 = 180°

11y - 7 = 180°

11y = 180 + 7

11y = 187

y = 187/11

y = 17

Therefore, the values of the variables x and y for the cyclic quadrilateral are 9 and 17 respectively.

Step-by-step explanation:

One way Olivia might have moved ABCDE onto A"B"C"D"E" is by first reflecting ABCDE over the x-axis, and then translating it 4 units to the left and 6 units down.

1) This would map point A to A", B to B", C to C", D to D", and E to E", creating A"B"C"D"E".

2) Angelica's transformation does not result in a figure that matches A"B"C"D"E". Reflecting ABCDE over the y-axis would map point A to A", B to E", C to D", D to C", and E to B", so the shape would be flipped horizontally. Translating it up 8 units would then shift the shape up, but it would still be horizontally flipped, so it would not match A"B"C"D"E".

3) Michael's claim is not correct. Translating ABCDE diagonally 8 units up and 10 units right would move point A to point J, which is not on A"B"C"D"E". The other points would also not be in their correct positions, so the resulting shape would not match A"B"C"D"E". To get to A"B"C"D"E" with one transformation, Michael would need to use a combination of translation, rotation, and/or reflection.

Case E: y = - x + 1 / 2

Case F: y = - (1 / 3) · x + 20 / 3

Case E: k = 1 / 2, m = - 1

y = - x + 1 / 2

Case F: Parallel to x - 3 · y = 9, (x, y) = (2, 6)

The volume of the resulting solid revolved around the x-axis is equal to  28.274 cubic units (round to the nearest thousandth).

Vertices of the right triangle are,

(0, 0), (0, 3) and (-4, 0)

To obtain the solid formed by revolving the given right triangle about the x-axis, use the disk method.

The cross-sectional area of the solid at a given height is a circle with radius = distance between the x-axis and the upper edge of the triangle at that height.

The height of the triangle is 3 units,

and the base of the triangle is 4 units.

So, the equation of the hypotenuse of the right triangle can be found as follows,

y = (3/4)x + 3

Now, let us consider a horizontal slice of the solid at a distance y units above the x-axis.

The radius of the circle at this height is ,

r = y - 3

The area of the circle at this height is ,

A = πr²

   = π(y - 3)²

The limits of integration are y = 0 the x-axis to y = 3 the height of the triangle.

Using the disk method, the volume of the solid is,

V = [tex]\int_{0}^{3}[/tex] π(y - 3)²dy

Evaluating the integral, we get,

⇒ V = π /3 ( y - 3 )³[tex]|_{0}^{3}[/tex]

⇒ V = π/3 [( 3- 3 )³ - ( 0 -3)³ ]

⇒ V = (π /3) ( 27)

⇒V  = 9π

⇒V  = 9 (3.1415)

Rounding to the nearest thousandth gives,

V ≈ 28.274

Therefore, the volume of the solid formed by revolving the given right triangle about the x-axis is approximately 28.274 cubic units.

The measure of angle A in triangle ABC is approximately 113.8 degrees.

To find the measure of angle A (LA) in triangle ABC, we can use the Law of Cosines:

c² = a² + b² - 2ab*cos(C)

where c is the length of the side opposite to angle C, and a and b are the lengths of the other two sides.

In this case, we want to find LA, which is opposite to side a (BC). So we can rewrite the Law of Cosines as:

cos(A) = (b² + c² - a²) / 2bc

Plugging in the values we have:

cos(A) = (24.1² + 15.7² - 25.3²) / (2 * 24.1 * 15.7)

cos(A) = -0.3694

Now we need to find the inverse cosine (cos⁻¹) of -0.3694 to get the measure of angle A:

A = cos⁻¹(-0.3694)

Using a calculator, we get:

A ≈ 113.8 degrees

Answer:

k = 1

Step-by-step explanation:

given a polynomial f(x) divided by (x + h) with a remainder of 0 , then (x + h) is a factor of f(x) and f(- h) = 0

here the polynomial is divided by (x + 1)

then substitute x = - 1 into the polynomial and equate to zero

k(- 1)³ + (- 1)² - 5(- 1) - 5 = 0

- k + 1 + 5 - 5 = 0

- k + 1 = 0 ( subtract 1 from both sides )

- k = - 1 ( multiply both sides by - 1 )

k = 1

Freezer B is better to buy in terms of dollars per cubic foot.

We have,

Dimensions of Freezer A = 1 ft x 1 ft x 5 ft

Sale price of Freezer A = $499.99

Dimensions of Freezer B = 1.5 ft x 1.5 ft x 4 ft

Sale price of Freezer B = $149.99

Now, Dollars per cubic foot for Freezer A

= (1 x 1 x 5)/ 499.99

= 0.01

The missing value for the quadratic function is given as follows:

y = -3.

As a function of it's roots x* and x**, the quadratic function is defined as follows:

y = a(x - x*)(x - x**)

In which a is the leading coefficient.

The roots of the function are the values of x when y = 0, hence:

x* = -4, x** = -2.

Thus:

y = a(x + 4)(x + 2)

y = a(x² + 6x + 8).

When x = 0, y = -8, hence the leading coefficient a of the function is given as follows:

8a = -8

a = -1.

Hence:

y = -x² - 6x - 8;

The missing value is the value of y when x = -1, hence:

An expression that represents the amount of canned food collected so far by the three friends is 8x² + 2xy - 4.

An expression that represents the number of cans the friends still need to collect to meet their goal is 4x² - 4xy + 2.

From the information provided above, we can logically deduce the following number of canned food collection expressions for each friend:

Jessa; 3x²

Tyree: 5x² - 8

Ben: 2xy + 4

Canned food collection goal: 12x² - 2xy - 2

Therefore, an expression that represents the total amount of canned food collected so far by the three friends can be calculated and written as follows;

Total amount collected so far = 3x² + 5x² - 8 + 2xy + 4

Total amount collected so far = 8x² + 2xy - 4

In order to meet the goal, they need to collect this amount:

Remaining canned foods = 12x² - 2xy - 2 - (8x² + 2xy - 4)

Remaining canned foods = 12x² - 2xy - 2 - 8x² - 2xy + 4

We can prove that the quadratic equation x² + (1 - k)x + k - 3 = 0 has two real roots for all real values of k.

The discriminant of the quadratic equation ax² + bx + c = 0 is given by Δ = b² - 4ac.

If Δ is positive, the equation has two real roots. If Δ is zero, the equation has one real root. If Δ is negative, the equation has two complex roots.

For the given equation, x² + (1 - k)x + k - 3 = 0, we can find the discriminant:

Δ = (1 - k)² - 4(k - 3)

= 1 - 2k + k² - 4k + 12

= k² - 6k + 13

To show that the roots are real for all real values of k, we need to show that Δ ≥ 0 for all k.

Δ = k² - 6k + 13

= (k - 3)² + 4

Since the square of any real number is non-negative, we have (k - 3)² ≥ 0. Therefore, Δ = (k - 3)² + 4 ≥ 4 for all real values of k.

Since Δ is always positive or zero, the quadratic equation x² + (1 - k)x + k - 3 = 0 has two real roots for all real values of k.
