Find the radius of the button. A circular button with a diameter of 3 and half inches.

Answer:

y = 40.

Step-by-step explanation:

The opposite sides of a cyclic quadrilateral sum to 180, so:

3y + 2y - 20 = 180

5y = 180 + 20 = 200

y = 40.

Step-by-step explanation:

75.34

Step-by-step explanation:

1.To find the circumference, you have to multiply the diameter times pi (3.14).

2.The radius (12) is half of the diameter

3. The diameter (12x2) is 24.

4. 24x3.14 is 75.36

So, the approx. circumference is 75.36.

Answer:75ft

Answer:

1248 cubic feet

Answer:

Step-by-step explanation:

50% is [tex]\frac{50}{100}[/tex] but we're working with 64 units, not 100. So, we must find a number that represents 50 but in 64 units.

[tex]\frac{50}{100}=\frac{x}{64}[/tex]

If you solve for x, you get:

[tex]x=\frac{50*64}{100}\\ x=32[/tex]

[tex]\frac{50}{100}=\frac{32}{64}[/tex]

Answer:

Given:

x > 0

y > 0

And,

x + 3y < 15

4x + y < 16

<=>

4x + 12y < 60

4x + y < 16

<=>

11y < 44

<=> y < 4

Otherwise

x + 3y < 15

4x + y < 16

<=>

x + 3y < 15

12x + 3y < 48

<=>

11x < 33

<=>

x < 3

=> C = 3x + 2y < 3*3 + 2*4 = 9 + 8 = 17

=>  C < 17

Hope this helps!

:)

The maximum value of  C is an illustration of objective functions

The maximum value of C is 25

The objective function is given as:

[tex]\mathbf{C = 3x + 2y}[/tex]

The constraints are:

[tex]\mathbf{x + 3y < 15}[/tex]

[tex]\mathbf{4x + y < 16}[/tex]

[tex]\mathbf{x,y > 0}[/tex]

Plot the graphs of the constraints

From the graph (see attachment), the only optimal point is (3,4)

Substitute 3 for x and 4 for y in the objective function.

So, we have:

[tex]\mathbf{C = 3x + 2y}[/tex]

[tex]\mathbf{C = 3(3) + 2(4)}[/tex]

[tex]\mathbf{C = 9 + 8}[/tex]

[tex]\mathbf{C = 17}[/tex]

Hence, the maximum value of C is 17

Inequality form:

X < -6

Interval Notation:

(-♾, -6)

Answer:

10626 different arrangements

Step-by-step explanation:

As we have a total of 23 students and we want to form groups of 3, where the order of the 3 students matters, we can solve this problem using a permutation of 23 choose 3.

The formula for a permutation of n choose p is:

P(n,p) = n! / (n-p)!

So, using n = 23 and p = 3, we have:

P(23,3) = 23! / (23-3)! = 23! / 20! = 23 * 22 * 21 = 10626

So we have a total of 10626 different arrangements of first, second and third place.

Answer:

x = - 12, x = 2

Step-by-step explanation:

Given

x² + 10x = 24

To complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(5)x + 25 = 24 + 25

(x + 5)² = 49 ( take the square root of both sides )

x + 5 = ±  = ± 7 ( subtract 5 from both sides )

No solution

Step-by-step explanation:

18x - 5 < 18x - 6

-18x        -18x               Subtract 18x from both sides

-5 < -6                         There is no solution because -5 is not less than -6.

Answer:

d. (6,-4)

Step-by-step explanation:

After 180° rotation:

(x , y) --> (-x,-y)

(-6,4) --> (6,-4)

Step-by-step explanation:

Step 1:  Solve using the first point

(2, 28)

[tex]28 = a(2)^3 + b(2)^2 + c(2) + d[/tex]

[tex]28 = 8a + 4b + 2c + d[/tex]

Step 2:  Solve using the second point

(-1, -5)

[tex]-5 = a(-1)^3 + b(-1)^2 + c(-1) + d[/tex]

[tex]-5 = -a + b - c + d[/tex]

Step 3:  Solve using the third point

(4, 220)

[tex]220 = a(4)^3 + b(4)^2 + c(4) + d[/tex]

[tex]220 = 64a + 16b + 4c + d[/tex]

Step 4:  Solve using the fourth point

(-2, -20)

[tex]-20 = a(-2)^3 + b(-2)^2 + c(-2) + d[/tex]

[tex]-20 = -8a + 4b - 2c + d[/tex]

Step 5:  Combine the first and fourth equations

[tex]28 - 20 = 8a - 8a + 4b + 4b + 2c - 2c + d + d[/tex]

[tex]8 = 8b + 2d[/tex]

[tex]8 - 8b = 8b - 8b + 2d[/tex]

[tex](8 -8b)/2 = 2d/2[/tex]

[tex]4 - 4b = d[/tex]

Step 6:  Solve for c in the second equation

[tex]-5 + 5 = -a + b - c + d + 5[/tex]

[tex]0 + c = -a + b - c + c + d + 5[/tex]

[tex]c = -a + b + d + 5[/tex]

Step 7:  Substitute d with the stuff we got in step 5

[tex]c = -a + b + (4 - 4b) + 5[/tex]

[tex]c = -a + b + 4 - 4b + 5[/tex]

[tex]c = -a - 3b + 9[/tex]

Step 8:  Substitute d and c into the first equation

[tex]28 = 8a + 4b + 2(-a - 3b + 9) + (4 - 4b)[/tex]

[tex]28 = 8a + 4b - 2a - 6b + 18 + 4 - 4b[/tex]

[tex]28 - 22 = 6a - 6b + 22 - 22[/tex]

[tex]6 / 6 = (6a - 6b) / 6[/tex]

[tex]1 + b = a - b + b[/tex]

[tex]1 + b = a[/tex]

Step 9:  Substitute a, b, and c into the third equation

[tex]220 = 64(1 + b) + 16b + 4(-(1 + b) - 3b + 9) + (4 - 4b)[/tex]

[tex]220 = 64 + 64b + 16b + 4(-1 - b - 3b + 9) + 4 - 4b[/tex]

[tex]220 - 100 = 60b + 100 - 100[/tex]

[tex]120 / 60 = 60b / 60[/tex]

[tex]2 = b[/tex]

Step 10:  Find a using b = 2

[tex]a = b + 1[/tex]

[tex]a = (2) + 1[/tex]

[tex]a = 3[/tex]

Step 11:  Find c using a = 3 and b = 2

[tex]c = -a - 3b + 9[/tex]

[tex]c = -(3) - 3(2) + 9[/tex]

[tex]c = -3 - 6 + 9[/tex]

[tex]c = 0[/tex]

Step 12:  Find d using b = 2

[tex]d = 4 - 4b[/tex]

[tex]d = 4 - 4(2)[/tex]

[tex]d = 4 - 8[/tex]

[tex]d = -4[/tex]

Answer:  [tex]a = 3, b = 2, c = 0,d = -4[/tex]

Answer:

a = 3

b = 2

c = 0

d = -4

Step-by-step explanation:

Form 4 equations and solve simultaneously

28 = a(2)³ + b(2)² + c(2) + d

28 = 8a + 4b + 2c + d (1)

-5 = -a + b - c + d (2)

220 = 64a + 16b + 4c + d (3)

-20 = -8a + 4b - 2c + d (4)

(1) + (4)

28 = 8a + 4b + 2c + d

-20 = -8a + 4b - 2c + d

8 = 8b + 2d

d = 4 - 4b

Equation (2)

c = -a + b + d + 5

c = -a + b + 4 - 4b+ 5

c = -a - 3b + 9

28 = 8a + 4b + 2c + d (1)

28 = 8a + 4b + 2(-a - 3b + 9) + 4 - 4b

28 = 6a - 6b + 22

6a - 6b = 6

a - b = 1

a = b + 1

220 = 64a + 16b + 4c + d (3)

220 = 64(b + 1) + 16b + 4(-b - 1 - 3b + 9) + 4 - 4b

220 = 60b + 100

60b = 120

b = 2

a = 2 + 1

a = 3

c = -3 - 3(2) + 9

c = 0

d = 4 - 4(2)

d = -4

A rotation of 90° about the origin includes the interchange of the position of  x, and y in the ordered pair and a change of one of the signs of the pair.

The option that shows the pre-image of triangle X'Y'Z' before the figure was rotated 90° about the origin is the option;

Reasons:

The given transformation the gives the X'Y'Z' = 90° rotation about the origin

The given coordinates of X'Y'Z' are;

X'(-2, 2), Y'(0, 6), and Z'(1, 1)

Required:

The figure that shows the preimage of X'Y'Z'

Solution:

Given that X'Y'Z' is obtained by the rotation of XYZ 90°, therefore, the

coordinates of XYZ are given by the rotation of X'Y'Z' in the reverse

direction either counterclockwise and clockwise.

(x, y) [tex]\underrightarrow {R_{90^{\circ}}}[/tex] (-y, x)

(x, y) [tex]\underrightarrow {R_{-90^{\circ}}}[/tex] (y, -x)

Therefore, we have;

X'(-2, 2) [tex]\underrightarrow {R_{90^{\circ}}}[/tex] X(-2, -2)

Y'(0, 6) [tex]\underrightarrow {R_{90^{\circ}}}[/tex] Y(-6, 0)

Z'(1, 1) [tex]\underrightarrow {R_{90^{\circ}}}[/tex] Z(-1, 1)

Similarly, we get;

X'(-2, 2) [tex]\underrightarrow {R_{-90^{\circ}}}[/tex]  X(2, 2)

Y'(0, 6) [tex]\underrightarrow {R_{-90^{\circ}}}[/tex]  Y(6, 0)

Z'(1, 1) [tex]\underrightarrow {R_{-90^{\circ}}}[/tex] Z(1, -1)

The above coordinates of XYZ; X(2, 2), Y(6, 0), and Z(1, -1), corresponds to

the option;

On a coordinate plane, a triangle has points X(2, 2), Y(6, 0), and Z(1, -1).

Therefore, XYZ was rotated 90° clockwise to form X'Y'Z'
