The vertex F(−2, 4) in the dilated image has coordinates of (−6, 12) option (B) F' is correct.

The transformation dilation is used to resize an item. Dilation is a technique for making items appear larger or smaller. The image created by this transformation is identical to the original shape.

It is given that:

The coordinates are:

Rectangle EFGH has vertices E(−3, 4), F(−2, 4), G(−2, −2), and H(−3, −2).

After applying dilation with a scale factor of 3:

E(−3, 4) → E'(-3x3, 4x3) = E'(-9, 12)

Similarly,

F(−2, 4) → F'(-6, 12)

G(−2, −2) → G'(-6, -6)

H(−3, −2) → H'(-9, -6)

Thus, the vertex F(−2, 4) in the dilated image has coordinates of (−6, 12) option (B) F' is correct.

When 28.1 grams of Cl₂ reacts with excess H₂, approximately 92.34 kJ of heat is released.

The balanced chemical equation for the reaction is:
H₂(g) + Cl₂(g) → 2HCl(g)

According to the equation, 1 mole of Cl₂ reacts with 1 mole of H₂ to produce 2 moles of HCl.
To find the amount of heat released when 28.1 grams of Cl₂ reacts with excess H₂, we need to use the molar mass of Cl₂ and the given enthalpy change (AH) value.

Step 1: Calculate the number of moles of Cl₂:
Molar mass of Cl₂ = 2 x atomic mass of Cl = 2 x 35.45 g/mol = 70.9 g/mol
Number of moles of Cl₂ = Mass of Cl₂ / Molar mass of Cl₂
                     = 28.1 g / 70.9 g/mol
                     ≈ 0.396 mol

Step 2: Use the mole ratio from the balanced equation to determine the moles of HCl produced:
1 mole of Cl₂ produces 2 moles of HCl.
Number of moles of HCl produced = Number of moles of Cl₂ x (2 moles of HCl / 1 mole of Cl₂)
                              = 0.396 mol x 2
                              = 0.792 mol

Step 3: Calculate the heat released using the given enthalpy change (AH) value:
The given AH value is -186 kJ. Since the reaction produces 2 moles of HCl, we can use a proportion to calculate the heat released:
Heat released = Number of moles of HCl x (AH / Moles of HCl produced)
             = 0.792 mol x (-186 kJ / 2 mol)
             = -92.34 kJ

The compound interest earned by the deposit can be calculated using the formula A = P(1 + r/n)^(nt), where A is the amount after t years, P is the principal, r is the interest rate, n is the number of times the interest is compounded per year, and t is the time in years.

In this case, P = $550, r = 5.1%, n = 1 (compounded annually), and t = 10 years. Plugging in these values, we get:

A = 550(1 + 0.051/1)^(1*10) = $887.07

Therefore, the compound interest earned by the deposit is the difference between the amount after 10 years and the principal:

CI = A - P = $887.07 - $550 = $337.07

Rounding to the nearest cent, the answer is $337.06.

Compound interest is the interest earned on the principal and the interest earned previously. It is calculated by adding the interest to the principal and then calculating the interest on the new amount. This process is repeated for each compounding period.

The formula A = P(1 + r/n)^(nt) is used to calculate the amount after t years. Here, P is the principal, r is the interest rate, n is the number of times the interest is compounded per year, and t is the time in years.

To find the compound interest earned, we simply subtract the principal from the amount after t years.

The compound interest earned by the deposit is $337.06. This means that the initial investment of $550 has grown to $887.07 after 10 years due to the effect of compound interest. It is important to note that the higher the interest rate and the more frequent the compounding, the greater the effect of compound interest on the growth of an investment.

Answer:

The 5th row has 24 chairs, and therefore not enough chairs for 100 people.

Step-by-step explanation:

The equation for this situation is , f(x) =  4x+4  The reason for this is, there is 4 chairs added to every row, so in order to make row number one make sense, you must subtract 4 to find the y-intercept which is also 4.

To find if the 5th row has enough for 100 people, you must plug 5 in for x

The 5th row has 24 chairs, and therefore not enough chairs for 100 people.

The required chairs in the 5th row there is 24 chairs and 5 rows are not enough to accommodate 100 people.

Arithmetic progression is the series of numbers that have common differences between adjacent values are common.

Here,
A given scenario is of arithmetic progression,
Let the first term be a = 8,
and the common difference between chairs is d = 4,
Now,
Let the number of rows be n,

Now,
The explicit arithmetic formula is given as,
Number of chairs = 8 + (n - 1)4
Now put n = 5
Number of chairs = 8 + (5 - 1) 4
                           = 8 + 16
                           = 24

So, in the 5th row, there will be 24 chairs.

Now,
For 100 people number of chairs would be 100
Apply the sum formula of arithmetic progression,

Where sum gives the total number of chairs for n rows,

Sum = n / 2 (a + l)
Sum = 5 / 2(8 + 24)
       = 5 / 2 (32)
       = 5 × 16
       = 80 chairs

Thus, the required chairs in the 5th row there is 24 chairs and 5 rows are not enough to accommodate 100 people.

The application rate is 3 (per DM$).

The given below table shows the monthly production volume, direct materials, direct labor, and manufacturing overheads for the past three months at Gizzard Wizard (GW):

Month Prod. Volume DM ($)DL ($)MOH ($)May 1000$400.00$600.00$1200.00

June 400160.00240.00480.00

July 1600640.00960.001920.00

By using DM$ to apply overhead, we have to find the application rate. We know that the total amount of manufacturing overheads is calculated by adding the cost of indirect materials, indirect labor, and other manufacturing costs to the direct costs. The formula for calculating the application rate is as follows:

Application rate (per DM$) = Total MOH cost / Total DM$ cost

Let's calculate the total cost of DM$ and MOH:$ Total DM$ cost = $400.00 + $160.00 + $640.00 = $1200.00$

Total MOH cost = $1200.00 + $480.00 + $1920.00 = $3600.00

Now, let's calculate the application rate:Application rate (per DM$) = Total MOH cost / Total DM$ cost= $3600.00 / $1200.00= 3

Therefore, the application rate is 3 (per DM$).

Hence, the required answer is "The application rate for GW is 3 (per DM$)."

Answer:

C. Different sample proportions would result each time, but for either sample size, they would be centered (have their mean) at the true population proportion.

Step-by-step explanation:

From the given information;

A political polling agency wants to take a random sample of registered voters and ask whether or not they will vote for a certain candidate.

A random sample is usually an outcome of any experiment that cannot be predicted before the result.

SO;

One plan is to select 400 voters, another plan is to select 1,600 voters

If the study were conducted repeatedly (selecting different samples of people each time);

Different sample proportions would result each time, but for either sample size, they would be centered (have their mean) at the true population proportion.  This is because a sample proportion deals with random experiments that cannot be predicted in advance and they  are  quite known to be centered about the population proportion.

The value of the trigonometry are sin(Π-Ɵ) = 0.84 and sin(Π + Ɵ) = -0.84

According to the question, there is a circle whose radius is 1 and the ray intersects the circle at point (0.54, 0.84).

We need to find the trigonometric values, that is

 sin(Π-Ɵ) = sin(Ɵ) as we know that when the angle is in third quadrant sin is positive.

 sin(Π+Ɵ) = -sin(Ɵ) as we know that when the angle is in fourth quadrant sin is negative.

Also note that,  sinƟ = perpendicular/hypotenuse

Perpendicular = 0.84 as the perpendicular length will be equal to the length of the y-axis

Hypotenuse = 1 as the hypotenuse will be the radius of the circle which is formed by the ray.

Thus, sinƟ = 0.84/1 = 0.84

Hence, sin(Π-Ɵ) = 0.84

  And sin(Π+Ɵ) = -0.84

The region in the plane consists of all points within or on a circle of radius 7 centered at the origin, with a shaded sector between the angles -2 and 2.

To sketch the region in the plane consisting of points whose polar coordinates satisfy the given conditions, we consider the range of values for the radial distance (r) and the angle (θ).

Given: 0 ≤ r ≤ 7, −2 ≤ θ ≤ 2

The radial distance (r) ranges from 0 to 7, which means the points lie within or on a circle of radius 7 centered at the origin.

The angle (θ) ranges from -2 to 2, which corresponds to a sector of the circle.

Combining these conditions, the region in the plane consists of all the points within or on the circle of radius 7 centered at the origin, with the sector of the circle from -2 to 2.

To sketch this region, draw a circle with a radius of 7 centered at the origin and shade the sector between the angles -2 and 2.

A linear expression is an algebraic expression in which each term is a constant or a variable raised to the first power. To put it another way, none of the exponents can be greater than 1.

\(x^2\) is a variable raised to the second power, whereas x is a variable raised to the first power.

A linear expression is 2x - y + 3.

A constant is represented by the number,  example 5.

Given,

expression (a - 4) and (4a + 16)

subtracting (a - 4) from (4a + 16), results in

= (4a + 16) - (a - 4)
