Spontaneous reactions are those that occur with no input of energy, and are characterized by a negative standard Gibbs free energy, a positive standard cell potential, and an equilibrium constant greater than one.

A spontaneous reaction is one that occurs without any external input of energy, and it always proceeds in a single direction. Characteristics of a spontaneous reaction include the following:

1. The standard Gibbs free energy of the reaction (δG°) is negative, indicating that the reaction is energetically favorable and will occur on its own.

2. The standard cell potential (δE°cell) is greater than zero, indicating that the reaction is capable of producing a useful electrical current.

3. The reaction's equilibrium constant (K) is greater than one, indicating that the reaction's products are favored over its reactants at equilibrium.

In summary, spontaneous reactions are those that occur with no input of energy, and are characterized by a negative standard Gibbs free energy, a positive standard cell potential, and an equilibrium constant greater than one.

Answer:

a) 19 cm

Step-by-step explanation:

Area of a parallelogram: b • h

Given values:

Substitute these values into the formula:

⇒ A = b • h

⇒ 228 = b • 12 [multiply]

⇒ 228 = 12b [divide both sides by 12]

⇒ 228 ÷ 12 = 12b ÷ 12

⇒ 19 = b

Therefore, the base of the parallelogram is 19 cm.

Answer:

Step-by-step explanation:

The strength of a linear relationship between two variables is typically measured by the correlation coefficient (r) or the coefficient of determination (r^2). A value of r or r^2 closer to 1 indicates a stronger positive linear relationship, whereas a value closer to -1 indicates a stronger negative linear relationship. A value of r or r^2 closer to 0 indicates a weaker or no linear relationship.

Looking at the given regression equations and their correlation coefficients, the regression with the weakest linear relationship between x and y is Regression 3:

Regression 1: y = -5.8x - 6.5, r = -0.7621

Regression 2: y = 2.4x - 14.7, r = 0.809

Regression 3: y = -7.4x - 17.4, r = -0.233

Regression 4: y = -3.4x - 8.5, r = -0.6121

Regression 3 has the lowest absolute value of r (0.233), indicating the weakest or no linear relationship between x and y. Therefore, Regression 3 represents the weakest linear relationship between x and y among the given options.

5 laps

400 meters each lap.

So, to answer this we have to multiply the number of laps by the length of each lap:

400 m x 5 = 2,000 meters

Then we have to convert into kilometers.

Since 1 km= 1000 meters

We have to divide the value in meters by 1000:

2,000 / 1,000 = 2 km

2 kilometers

Answer:

5 laps x 400m = 2000m = 2km

Given:  -x+3y+z=7      - (i)

            x+y=1            - (ii)

Rearrange the equation (i) and (ii),

we get,   -x+3y+z-7=0   -(iii)

Positive curve graphs will be upward-sloping.

Negative curve graphs will be downward-sloping.

Both graphs in the first image attached below, show curves sloping upward from left to right. As with upward-sloping straight lines, we can say that generally the slope of the curve is positive. While the slope will differ at each point on the curve, it will always be positive.

In the graphs in the second image attached, both of the curves are downward sloping. Straight lines that are downward sloping have negative slopes; curves that are downward sloping also have negative slopes. The slopes change from point to point on a curve, but all of the slopes along these two curves will be negative.

Therefore, the initial number of party favor bags Razi had to fill is 20.

To determine the initial number of party favor bags Razi had to fill, we need to analyze the relationship between the time and the number of bags remaining.

Looking at the table, we can observe that the number of bags remaining decreases by 4 for every additional minute of work. This suggests a constant rate of filling the bags.

From the given data, we can see that at the starting time (4 minutes), Razi had 36 bags remaining. This implies that for each minute of work, 4 bags are filled.

To calculate the initial number of bags, we can subtract the number of bags filled in 4 minutes (4 x 4 = 16) from the number of bags remaining initially (36).

The definite integral of 7x/(x-6) dx over the interval [0,6] is 63.

To evaluate the definite integral of 7x/(x-6) dx over the interval [0,6], we can use the method of partial fractions:

7x/(x-6) = A + B(x-6)

Multiplying both sides by (x-6), we get:

7x = A(x-6) + B(x-6)^2

Setting x=6, we get:

42A = 0

A = 0

Differentiating both sides and setting x=6, we get:

7 = B(6-6)*2

B = 7/36

Substituting A and B back into the original equation, we have:

7x/(x-6) = 7/36 * (x-6) + 0

Integrating from 0 to 6, we get:

∫(0 to 6) 7x/(x-6) dx = [7/36 * (x-6)^2] from 0 to 6 = 63

Therefore, the definite integral of 7x/(x-6) dx over the interval [0,6] is 63.

~hope this helps~

To meet your goal, you should consume 13377 calories in one week.

Percentage refers to a number that is "out of one hundred." As with fractions and decimals, percentages are used in mathematics to represent subsets of a whole.

Given,

you currently consume about 2100 calories per day.

You want to reduce your daily calorie consumption by about 9%.

That means,

9% of 2100

= 9 x 2100 / 100

= 189 calories

To find the number of calories you should consume in one week to meet your goal:

Multiply by 7 to reduced consumption in one day.

7 x 189

= 1323 calories.

Now, subtraction;

One week of consumption - reduced consumption

= (2100 x 7) - 1323

= 13377

Therefore, in one week you should consume 13377 calories.

Angel receives 300 votes which is 60% of total votes.

Therefore we can determine 60% = 300

The next thing to do would be to determine 1% and we can do this by dividing both sides by 60:

60% = 300

1% = 5

Then multiply both sides by 100 to determine 100% of total votes (total amount of students who voted):

1% = 5

100% = 500

Therefore 500 students voted in the election.

Answer:

500 students

Step-by-step explanation:

300=60%

300x2=600

(turning the 300 into 600 helps it make sense)

600/3=200

200x5= 1000

B. 8.4.

The Pythagorean Theorem states that in a right-angled triangle, the square of the length of the hypotenuse (the longest side) is equal to the sum of the squares of the lengths of the other two sides.

The theorem is expressed as follows:

c² = a² + b².

In which:

For this problem, we have that:

Hence the radius r is obtained as follows:

r² + 9² = 12.3²

Given:;

Marked price of a fan = Rs. 1250.

Discount percent = 6%.

To find:

The selling price of the fan.

Solution:

We have,

Marked price of a fan = Rs. 1250.

Discount  percent= 6%.

So,

Selling price = Marked price  - Discount

\(S.P.=1250-\dfrac{6}{100}\times 1250\)

\(S.P.=1250-75\)

\(S.P.=1175\)

Therefore, the selling price of the fan is Rs. 1175.

The answer of the given question based on the trigonometry is , to calculate YZ, we should use the cosine function with the angle 35.5°.

The sine function is a mathematical function that relates the ratios of the lengths of two sides of a right triangle with the measure of one of its non-right angles. Specifically, the sine of an angle in a right triangle is defined as the ratio of the length of the side opposite to the angle to the length of the hypotenuse.

To use trigonometry to calculate YZ, we need to find a trigonometric ratio that involves the given side XZ and the angle opposite the requested side, which is angle YXZ. We don't have the measure of this angle, but we know that it is supplementary to the given angle 35.5°, so it must measure:

180° - 35.5° = 144.5°

We can use this angle and the given side XZ to find the length of YZ using the sine or cosine function.

In this case, the length of the opposite side is YZ, the length of the hypotenuse is XZ, and the measure of the angle is 144.5°. So we can write:

sin(144.5°) = YZ / XZ

Solving for YZ, we get:

YZ = XZ * sin(144.5°)

On the other hand, the cosine function , this case, the length of the adjacent side is YZ, the length of the hypotenuse is XZ, and the measure of the angle is 35.5°. So we can write:

cos(35.5°) = YZ / XZ

Solving for YZ, we get:

YZ = XZ * cos(35.5°)

Therefore, to calculate YZ, we should use the cosine function with the angle 35.5°.
