Density is how much matter is contained within a volume. A dense object weighs more than a less dense object that is the same size. An object less dense than water will float on it; one with greater density will sink. The density equation is density equals mass per unit volume or D = M / V. (Hope this helped!)

The derivative of a function f(x) at a point x = a is defined as the limit of the difference quotient as h approaches zero:

f'(a) = lim (h → 0) [f(a + h) - f(a)] / h

What is derivative?

The derivative of a function in calculus measures the function's sensitivity to changes in its input variable. Specifically, at a particular point, it represents the function's rate of change with respect to its input variable at that moment.

The derivative of a function f(x) at a point x = a is defined as the limit of the difference quotient as h approaches zero:

f'(a) = lim (h → 0) [f(a + h) - f(a)] / h

This limit represents the instantaneous rate of change or slope of the function at the point x = a. The difference quotient is the change in the function value divided by the change in the input variable (or the distance between two points on the graph of the function).

The derivative is a fundamental concept in calculus, and it has many applications in various fields of science, engineering, and economics. It allows us to calculate important quantities such as velocity, acceleration, and marginal cost, and it is used to optimize functions and solve many real-world problems.

Sampling techniques are particularly important in quantitative research studies. In these studies, researchers aim to collect data from a subset of individuals or entities (the sample) to make inferences about a larger population.

Sampling techniques help researchers select participants from the population in an unbiased and systematic manner. By using appropriate sampling methods such as random sampling, stratified sampling, or cluster sampling, researchers can minimize sampling errors and increase the likelihood that the sample represents the characteristics of the population accurately.

By employing sound sampling techniques, researchers can enhance the external validity of their findings, allowing them to make meaningful and reliable generalizations about the larger population.

This is particularly crucial in fields such as public health, social sciences, market research, and opinion polling, where the goal is to draw valid conclusions about the broader target audience based on a representative sample.

Step-by-step explanation:

The measure of angle x is 70°.

Here we have the image of some triangles, and we want to find the value of the interior angle x in the left triangle.

What you need to remember here is that the sum of the interior angles of any triangle is always equal to 180°.

Then, for the left triangle, we can write:

30° + 80° + x° = 180°

Now we can solve that equation for x, then we will get:

x° = 180° - 80° - 30°

x = 70°

Answer:

5/12 hour or 25 minutes

Step-by-step explanation:

The formula is

distance = rate * time

changing minutes to hours (50 * 1 /60 ) = 5/6 hours

distance = 20 mph * 5/6 hours

distance = 50/3 miles

We need to go the same distance at 40 mph

50/3 = 40 mph * time

Multiply each side by 1/40

50 /3 * 1/40 = 40 * 1/40 *t

50/3 *1/40 =t

The double line connected to the double diamond symbol indicates that total participation between associated entities and that the double rectangle entity can not exist without the single rectangle entity connected to it. The reason behind it is that Double diamonds are always used to represent relationships between strong and weak entities. Strong Entity - Simple Rectangle Weak Entity - Double Rectangle.

An Entity Relationship diagram (ER) is a data modeling diagram used to represent the entities that will be modeled in a database, and the relationships between those entities (I use the one-to-many, one-to-one , many-to-many relationship terms themselves). When implementing a relational database, these relationships will determine which foreign keys I need to implement to relate one table to another. Diamonds represent sets of relationships in an ER diagram. A relationship set defines the relationship between two sets of entities in a database.

Proportional relationships are relationships between two variables where their ratios are equivalent. Another way to think about them is that, in a proportional relationship, one variable is always a constant value times the other. That constant is know as the "constant of proportionality".

In each of the table, we can check if proportionality exists.

In the first table, there's no proportionality.

In the second table, there's no proportionality

In the third table, there's no proportionality

In the fourth table, proportionality exist here which we can find the constant of proportionality.

What is function explain?

A function is defined as a relation between a set of inputs having one output each. In simple words, a function is a relationship between inputs where each input is related to exactly one output. Every function has a domain and co-domain or range.

Given that;

k(x) = x - 1

m(x) = x + 2

n(x) = x - 3

\(f(x) = k(x)\times m(x)\times n(x)\)

\(f(x) = (x-1)\times (x+2)\times (x-3)\)

\(f(x) = (x^2+x-2)(x-3)\)

\(f(x) = x^3 +x^2-2x-3x^3-3x+6\)

\(f(x) = x^3-2x^2-5x+6\)

a) k(x) = x-1,

   m(x) = x+ 2

    n(x) = x - 3

all  shown into the graph .

b)\(f(x) = (x-1)\times (x+2)\times (x+3)\)

   \(f(x) = x^3-2x^2-5x+6\)

∴degree of function is 3.

degree of function/polynomial is the highest power/degree of the polynomial's monomials.

c) for finding zeros put F(x) = 0 and solve for x

  \(f(x) = (x-1)\times (x+2)\times (x-3)\\f(0) = (0-1)\times (0+2)\times (0-3)\\\)

x = 1 , x = -2 and x = 3 are the zeros of f(x).

Step-by-step explanation: hope this helped!

Answer:

The radius of the circle with circumference 22cm is 3.5 cm

Step-by-step explanation:

The circumference of circumference of a circle is the distance of its closed boundary.

The circumference of a circle with radius r is given by the formula:

\(C = 2\pi r\)

Given

C = 22cm

Putting the values in the formula

\(22 = 2 * \frac{22}{7} * r\\22 = \frac{44}{7} * r\\r = \frac{7}{44} * 22\\r = \frac{7}{2}\\r = 3.5cm\)

Hence,

A conditional statement can be written as:

An example of this in real life is:

In this case:

p = it rains

q = the floor gets wet

The converse of that conditional is:

Notice that the conditional being true doesn't mean necessarily that its converse is true. For example, every time it rains the floor gets wet can be true, but the floor could get wet for other reasons, so the converse would not be true.

Also, the inverse of that conditional is:

As we see, the inverse of a true conditional statement is not necessarily true.

And the contrapositive of that conditional statement is:

Now, the contrapositive of a true conditional statement is always true. Notice that if every time it rains the floor gets wet, the only explanation for the floor not getting wet is that it does not rain.

1. The values which the given number sentences true are:

a) 11 b) 5 c) 36

2. After substituting the value of  x we get the value for y as :

a) 6 b) 0 c) 7 d) 15

a) x ₋ y = 25

b) 5 × p = q ÷ 2

c) 2y ₋ 14 = 6

2p = 4 ₊ 6

2p = 10

p = 10/2

p = 5

c) 1/3 y = 12

cross multiply.

y = 36

Now in the second exercise we are asked to substitute the x value and get the value of y.

a) y = 3x ₊ 2 if x =8

substitute x value in the equation.

y = 3(8) ₊ 2

y = 24 ₊ 2

y = 26

b) y = 4x ₋ 1 if  x = 1/4

y = 4(1/4) ₋ 1

y = 1 ₋ 1

y = 0

c) y = 0.2x ₊ 5 if x = 10

y = 0.2(10) ₊ 5

y = 2 ₊ 5

y = 7

d) y = 10x ₊ 12 if x = 0.3

y = 10(0.3) ₊ 12

y = 3 ₊ 12
