{y2+8y−128=0x=34⋅(y+4) ... The two right triangle are similar, so: BDAB=DEAC. From this, I obtain: ... AC=3x AB=4x (3x)²+(4x)²=225 x=3 BD=8 AB/AC=BD/DE 12/9=8/DE DE=6.

The length of segment DE in the given triangle is 6 units.

Trigonometric Ratios are defined as the values of all the trigonometric functions based on the value of the ratio of sides in a right-angled triangle.

Given that, a right-angled triangle ABC, with a segment DE, where tan B = 3/4, BC = 15 and DA = 4

Since, tan B = 3/4

Cos B = 4/5

Cos B = AB / BC

therefore,

4/5 = AB / 15

AB = 12

BD = AB - AD = 12-4

BD = 8

Now, Tan B = 3/4

DE / BD = 3/4

DE / 8 = 3/4

DE = 6 units

Hence, the length of segment DE in the given triangle is 6 units.

A is an n x n diagonal matrix with rank r , where rsn  and the statement (a)"O is an eigenvalue with algebraic muitiplicity n-r "  about A is true

Since A is an n x n diagonal matrix with rank r, the number of non-zero entries on the diagonal is r. This means that there are n - r zero entries on the diagonal.

For any diagonal matrix, the eigenvalues are simply the entries on the diagonal. Since there are n - r zero entries, the eigenvalue O has a geometric multiplicity of n - r.

Therefore, the correct statement is that O is an eigenvalue with geometric multiplicity n - r.

Answer:

The formula for the circumference of a circle is C = 2πr, where r is the radius and C is the circumference. The equation solved for r is r =c/2π .

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,

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

the radius of the circle is 30 cm when the circumference is 188.4 . The length of the boundary is its circumference.

A boy has traveled a certain distance if, after sprinting around the park once, he arrives at point "A" from point "A" in the first place. The park's circumference, which has the shape of a circle, is the length or border that it encompasses. The length of the boundary is its circumference.

calculation

Circumference=2πr

188.4=2×3.14×r

188.4=6.28×r

r= 188.4/6.28

radius=30cm

the radius of circle is 30 cm when the circumference is 188.4 .

Answer:

18 times  a green bead is drawn

Step-by-step explanation:

There are 20 beads in the basket.  The probability of picking a green bead is 6/20 = 3/10.  That means that a green bead would be picked 3/10 of the time.

So, 3/10(60) = 18 times  a green bead is drawn

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.

(a) k(x) = x-1, m(x) = x+ 2 , n(x) = x - 3  all  shown into the graph .

(b) The degree of the function fn(x) is 3.

(c) The zeros of the function fn(x) is x = 1 , x = -2 and x = 3.

(d)  The intervals over which the value of function f(x) is negative (0,6).

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).

d) for y-intercept put x = 0

f(0) = (0-1)(0+2)(0-3)

f(0)=6

y-intercept is (0,6).

What are Similar Triangles?

Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion .

Triangle QRS is similar to triangle FGH.

Let us find the length of unknown side.

By comparing the sides.

SR/QR=HF/HG

8/14 = x/7

Apply cross multiplication

14x = 56

Divide both sides by 14

x = 56/14

x = 4

HF = 4

8)

By properties of triangle we have

QP/BP=PR/PC

56/24= x/36

Apply cross multiplication

24x = 2016

Divide both sides by 24

x = 2016/24

x = 84

PR = 84

Hence the missing lengths of HF is 4 and missing length PR =84.

The double line connected to the double diamond symbol indicates:

B) Total participation between associated entities. ,and,

C) That the double rectangle entity can not exist without the single rectangle entity connected to it.

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. A double diamond represents a set of relationships linked to a set of weak entities. A set of weak entities is a collection without a primary key.

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.

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

5/12  of an hour

Changing back to minutes

5/12 * 60 =25

3. The number sentences are :

a) x ₋ y = 25

b) 5 × p = q ÷ 2

c) 2y ₋ 14 = 6

d) 15 × 4 = 4 ₋ (x₊y)

Given in the first bit we need to find the variables:

a) h ₊ 8 = 19

arrange the constants on one side.

h = 19 ₋ 8

h = 11

b) 2p ₋ 6 = 4

arrange the constants on one side.

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

y = 15

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.
