The image of vertex C under the given similarity transformation is (4, 2).

To apply the given similarity transformation, we need to perform two transformations: a rotation of 90 degrees counterclockwise about the origin (denoted by R) and a dilation by a factor of 2 (denoted by D2). We perform the transformations in order: first the rotation, then the dilation.

The image of a point (x, y) after a rotation of 90 degrees counterclockwise about the origin is (-y, x).

Thus, the image of C after the rotation is:

C' = (-(-2), 1) = (2, 1)

To find the image of C' after the dilation by a factor of 2, we multiply each coordinate by 2:

C" = (22, 21) = (4, 2)

Therefore, the image of vertex C under the given similarity transformation is (4, 2).

Based on the given tables for x = 1, 2, 3, and 4:

A. x: 1, 2, 3, 4. y: 1/2, 1, 1 1/2, 2

B. x: 1, 2, 3, 4. y: 1, 1/2, 1/3, 1/4

C. x: 1, 2, 3, 4. y: 7, 9, 13, 21

D. x: 1, 2, 3, 4. y: 0, 6, 16, 30

A linear function has a constant rate of change (slope). Let's calculate the differences in y-values for each table:

A. 1 - 1/2 = 1/2, 1 1/2 - 1 = 1/2, 2 - 1 1/2 = 1/2 (constant differences)

B. 1 - 1/2 = 1/2, 1/2 - 1/3 = 1/6, 1/3 - 1/4 = 1/12 (not constant)

C. 9 - 7 = 2, 13 - 9 = 4, 21 - 13 = 8 (not constant)

D. 6 - 0 = 6, 16 - 6 = 10, 30 - 16 = 14 (not constant)

Table A represents a linear function, as the differences in the y-values are constant (1/2).

Answer:

To solve this problem using spherical coordinates, we need to parameterize the region E using rho, theta, and phi. The cone z = x^2 + y^2 becomes phi = arctan(sqrt(x^2+y^2)/z), and the sphere x^2 + y^2 + z^2 = 1 becomes rho = 1, while x^2 + y^2 + z^2 = 64 becomes rho = 8. Then, we can integrate over the bounds rho = 1 to rho = 8, theta = 0 to theta = 2pi, and phi = 0 to phi = arctan(sqrt(x^2+y^2)/z), using the integrand x^2 + y^2 + z^2. The final result is a numerical value that represents the volume of the region E.

The value of x that makes the equation true is 0.2.

We have the Equation,

0.17x - 0.03 = 0.03x - 0.002

Simplifying the equation by adding 0.002 to both sides, we get:

0.17x - 0.028 = 0.03x

Subtracting 0.03x from both sides, we get:

0.14x - 0.028 = 0

Adding 0.028 to both sides, we get:

0.14x = 0.028

Dividing both sides by 0.14, we get:

x = 0.2

Therefore, the value of x that makes the equation true is 0.2.

The Trigonometric functions sine (s) and cosine (c) c(5) ≈ -0.2837.

The trigonometric functions sine (s) and cosine (c). To determine s(5), we need to know the value of sine of 5 radians.

We can use a scientific calculator or a trigonometric table to find this value.

Using a calculator, we can simply enter "sin(5)" and get the answer. On most calculators, the answer will be displayed as a decimal.

Using a trigonometric table, we can look up the value of sine for 5 radians. The table will list the sine of angles in degrees, so we need to convert 5 radians to degrees first. One radian is equal to 180/π degrees, so

5 radians = (5 × 180)/π degrees ≈ 286.48 degrees

Looking up the sine of 286.48 degrees in the table, we get:

sin(286.48°) ≈ -0.9589

Therefore, s(5) ≈ -0.9589.

To determine c(5), we need to know the value of cosine of 5 radians.

We can again use a calculator or a trigonometric table to find this value.

Using a calculator, we can enter "cos(5)" to get the answer.

Using a trigonometric table, we can look up the cosine of 5 radians. Since we have already converted 5 radians to degrees, we can simply look up the cosine of 286.48 degrees in the table. We get:

cos(286.48°) ≈ -0.2837

The greatest common factor is 3x² and GCF form of polynomial is

3x²(3x-2).

The given polynomial is

9x³ - 6x²

We can write it as;

3x²(3x-2)

We know that

The greatest common factor (GCF) that divides two or more numbers is known as the greatest common divisor (GCD). The highest common factor (HCF) is another name for it.

Therefore 3x² is its GCD.

Divide each term of polynomial 3c,

6c³ ÷ 3c = 2c² and  -9c ÷ 3c = -3

Thus,

3x²(3x-2) is the factored version of the polynomial with the highest common factor.

ok Let me explain :

Your argument of saying that the prob is 1/2 because there are 2 colors.

Had there been red, blue and green cubes you would have ended up calculating the prob as 1/3.

But this concept is wrong.

Prob is the chance occurrence of an event given many such events.

here since we have 4 cubes , the chance to pick any one is equal and that is 1/4

chance of picking a blue cube (1/4)*1 ....since we have one blue cube

chance of picking a red cube (1/4)*3 ....since we have one red cubes

You can think in a simple manner also, when something is greater in number (3>1) , the chances to pick that would obviously be more , so the probability cannot be half.

Answer:

[tex]Area = 1200m^2[/tex]

[tex]Perimeter = 148m[/tex]

Step-by-step explanation:

To find the area, just multiply the length by the width. In fact, we have a simple formula for this:

[tex]A(area) = lw[/tex]

[tex]l(length) = 50[/tex]

[tex]w(width)= 24[/tex]

Now, we need to plug in our values:

[tex]A(area)= 50*24[/tex]

Simplify:

[tex]A(area) = 1200[/tex]

Therfore, the area of the rectangle is:

[tex]1200m^2[/tex]

Now, lets move on to the perimeter(again, we have a simple formula!):

[tex]P(perimeter) = 2(l+w)[/tex]

Plug in our values from before:

[tex]P(perimeter)= 2(50 + 24)[/tex]

Answer:

Easy

Step-by-step explanation:

Let the time taken by Badri to complete the work be B. Then Amit can complete the work in 2.25 days, so we can write:

A = 2.25/B

Chetan takes double that of Badri to complete the work, so we can write:

C = 2B

Das takes double that of Chetan to complete the work, so we can write:

D = 2C = 4B

Let the first group consist of Amit and Das, and the second group consist of Badri and Chetan. Then the time taken by the first group to complete the work is:

T1 = A + D = 2.25/B + 4B

The time taken by the second group to complete the work is:

T2 = B + C = B + 2B = 3B

The difference between the times taken by the two groups to complete the work is:

T2 - T1 = 3B - (2.25/B + 4B) = 3B - 2.25/B - 4B

To minimize this difference, we take the derivative with respect to B and set it equal to zero:

d/dB (3B - 2.25/B - 4B) = 0

3 + 2.25/B^2 - 4 = 0

2.25/B^2 = 1

B = sqrt(2.25) = 1.5

Therefore, the time taken by Badri to complete the work is B = 1.5 days. Amit takes 2.25/1.5 = 1.5 days, Chetan takes 2B = 3 days, and Das takes 4B = 6 days.

To minimize the difference between the times taken by the two groups, we can take the faster group to consist of Amit and Badri, and the slower group to consist of Chetan and Das. The faster group takes 1.5 + 1.5 = 3 days to complete the work, and the slower group takes 3 + 6 = 9 days to complete the work. Therefore, the composition of the faster group could be Amit and Badri.

350 feet of fencing is needed to Enclose the backyard

To calculate the amount of fencing needed to enclose the backyard, we need to find the length of the three long sections of the fence.

Since the yard has a width of 65 feet and the two short sections of the fence each measure 10 feet, the total width of the yard plus the short sections of the fence is:

65 + 10 + 10 = 85 feet

Next, we need to find the length of the yard plus the two short sections of the fence. Since the length of the yard is 80 feet, and there are two short sections of the fence that are each 10 feet long, the total length of the yard plus the short sections of the fence is:

80 + 10 + 10 = 100 feet

Now we can calculate the length of the three long sections of the fence by adding up the perimeter of the yard plus the short sections of the fence and then subtracting the lengths of the two short sections of the fence:

2(85 + 100) - 2(10) = 350 feet

For this reason, 968 grams of coffee are needed to make a grande cup, and 998 grams are needed to make a jumbo cup.

Let's call the amount of coffee required to make a grande cup "g" and the amount of coffee required to make a jumbo cup "j". We want to find the values of g and j.

From the first piece of information, we know that:

60g + 59j = 61,644

From the second piece of information, we know that:

60g + 74j = 71,184

We can solve this system of equations by using the method of elimination. To eliminate g, we can subtract the first equation from the second equation:

(60g + 74j) - (60g + 59j) = 71,184 - 61,644

Simplifying, we get: 15j = 9540

Dividing by 15, we get: j = 636

Now that we know j, we can substitute it into either equation to find g. Let's use the first equation:

60g + 59(636) = 61,644

Simplifying, we get: 60g = 59,880

Dividing by 60, we get: g = 998

Therefore, the amount of coffee required to make a grande cup is 968 grams, and the amount of coffee required to make a jumbo cup is 998 grams.
