Answer:

-3

Step-by-step explanation:

A vertical line has undefined slope. These two points will be stacked one directly above (below) the other. The x will be the same in both points.

So the unknown in H(x,11) is -3

H (-3, 11)

Answer:

Below

Step-by-step explanation:

Vertical lines have slope = 'undefined'

   so the 'x' values in the two points have to be the same (vertical line)

             x = -3

As a side note:  Horizontal lines have a slope = 0

The distance Brett covered was 12 km, but his displacement was 8.6 km.

Displacement is a vector quantity that is measured as a change in an object's position, so the length of the position from the object's initial point to the object's end point.

Distance is a scalar quantity which is defined as the length of the entire path traveled by an object.

Given:

Distance = S₁ + S₂

Distance = 7 + 5

Distance = 12 km

The distance Brett has covered is 12 km.

Starting position = A

Final position = C

Displacement = AC

The displacement in this case is calculated by the Pythagorean theorem.

AC² = AB² + BC²

Displacement² = S₁² + S₂²

Displacement² = 7² + 5²

Displacement² = 49 + 25

Displacement² = 74

Displacement = [tex]\sqrt{74}[/tex]

Displacement = 8.6 km

The displacement that Brett has covered is 8.6 km.

The critical chi-square value for a chi-square test with seven classes and a p-value of 0.05 is 12.59.

A hypothesis is an educated guess or prediction about a relationship between variables. The critical chi-square value is the value that is used to make a decision about the hypothesis.

If the calculated chi-square value is greater than the critical chi-square value, we reject the null hypothesis, which states that there is no significant difference between the expected and observed frequencies.

For a chi-square test with seven classes, the critical chi-square value can be found by looking at the critical chi-square values for a p-value of 0.05, as shown in Table 1.

The degrees of freedom (df) is equal to the number of classes minus 1, so in this case, df = 7 - 1 = 6.

Therefore, the critical chi-square value for a chi-square test with seven classes and a p-value of 0.05 is 12.59.

The expression is,

⇒ f (x) = x³ - 2x² + 2x + 3

And, The factor is (x - 2)

Now, If (x - 2) is factor of function then x = 2 satisfy the function.

Step-by-step explanation:

Answer:

A. To find out how many eggs were in the flat, you need to use the information that 5 eggs were cracked, which is 1/6 of the total number of eggs in the flat.

If 5 eggs is 1/6 of the total number of eggs in the flat, then you can set up an equation to find the total number of eggs:

5 eggs = (1/6) * x

Where x is the total number of eggs in the flat.

To solve for x, you can cross-multiply to get:

5 eggs * 6 = 1 * x

Which gives:

x = 30

So there were 30 eggs in the flat.

B. To find out what percent of the eggs in the flat were not cracked, you need to know how many eggs were not cracked and divide that number by the total number of eggs in the flat, and then multiply by 100 to get the percentage.

Since 5 eggs were cracked and there were 30 eggs in the flat, you can find the number of eggs that were not cracked by subtracting the number of cracked eggs from the total number of eggs:

30 eggs - 5 eggs = 25 eggs

So 25 eggs were not cracked.

To find the percentage, you can divide the number of eggs that were not cracked by the total number of eggs in the flat and multiply by 100:

(25 eggs / 30 eggs) * 100 = 83.33%

So, 83.33% of the eggs in the flat were not cracked.

The graph of f(x)=√x+3+2 is shifted 3 units up and 2 units to the right from the parent graph of f(x)=√x.

Graph is a type of data structure that consists of a set of nodes (also called vertices) and edges. Each node is connected to other nodes by edges. Graphs are used to represent networks of communication, data organization, computational devices, the flow of computation, etc. They are also very useful for visualizing relationships between data points in a variety of fields.

The translation of the parent graph of f(x)=√x+3+2 is a vertical shift upward 3 units, followed by a horizontal shift to the right 2 units. This is represented by the bold line in the graph. In terms of the equation, the translation is represented by the addition of the 3 and the 2 to the function. The 3 causes the graph to shift vertically upward and the 2 causes the graph to shift horizontally to the right.

The larger radius of Cylinder P, which produces a lower the height per unit volume, compared to the smaller radius of Cylinder Q, indicates;

Graph a, matches the graph of Cylinder Q

Graph b, matches the graph of Cylinder P

The volume of water in a cylinder can be found using the formula;

V = π·r²·h

The volume of water is therefore, directly proportional to the volume, therefore, we get;

V ∝ h

V = k·h

Where; k = The constant of proportionality = The slope of the graph of the proportional relation

The equation, V = π·r²·h, indicates that we get;

k = π·r²

The value of the radius for P, r₁ is larger than the value of the radius for Q, r₂

Therefore, k₁ = π·r₁² > k₂ = π·r₂²

h = V/(π·r²)

Therefore, for a specified volume, V, V/π·r₁² < V/π·r₂², h₁ < h₂, and as the water is added, the height of the water in Cylinder Q increases more than the height of the water in Cylinder P, which indicates that we get;

y(t) = 3u(t) is a constant function that is equal to 3 for t >= 0 and equal to 0 for t < 0.

The function x(t) = 3tu(t) is a product of a scalar 3 and a unit step function u(t). Here, u(t) is defined as:

u(t) = 0 for t < 0

u(t) = 1 for t >= 0

So, x(t) is equal to 3t for t >= 0 and equal to 0 for t < 0.

The function y(t) is the derivative of x(t) with respect to t. To find the derivative of x(t), we use the power rule for differentiation, which states that the derivative of tx(t) is x(t) + t × dx(t)/dt.

So, we have:

y(t) = dx(t)/dt = d(3tu(t))/dt = 3u(t) + 3tu'(t) = 3u(t)

Here, u'(t) is the derivative of u(t) with respect to t, which is equal to the Dirac delta function δ(t).

So, we have:

y(t) = 3u(t) = 3 for t >= 0

y(t) = 0 for t < 0

A linear equation is one that has a degree of 1 as its maximum value. No variable in a linear equation, thus, has an exponent greater than 1. A linear equation's graph will always be a straight line.

The two points given are - (4,24) and (6,30)

The slope-intercept form of a linear equation is - y = mx + b, where m is the slope and b is the y-intercept.

To find the slope use the formula -

m = (y2 - y1)/(x2 - x1)

m = (30 - 24)/(6 - 4)

m = 6/2

m = 3

So, now the equation becomes - y = 3x + b

To find the y-intercept substitute the equation with x and y values -

24 = 3(4) + b

24 = 12 + b

b = 24 - 12

b = 12

Here in which bonds are concurrently breaking and forming new ones.

And it is extremely unstable and highly energetic.

We know that both intermediates and transition states are the states that are present between the reactants and the reaction's end products, on the other hand they differ in that intermediates have full bonds, are more stable than the substrate and therefore have a lower energy and have a discrete lifetime,

Here we know that instead of a transition state has only partial bonds and is least unstable, thus making it the state with the highest energy at the reaction profile.

Therefore the correct option is (a).

To know more about reaction here.
