Which equation gives the length of the altitude of ABC?

Which Equation Gives The Length Of The Altitude Of ABC?

Answers

Answer 1

Answer:

B. AD = sqrt(CD * BD)

Step-by-step explanation:

By the right triangle altitude theorem,

CD/AD = AD/BD

AD^2 = CD * BD

AD = sqrt(CD * BD)

Answer: B. AD = sqrt(CD * BD)

Answer 2

Answer:

B

Step-by-step explanation:

[tex]$\frac{CD}{AD} =\frac{AD}{BD} $[/tex]

[tex]AD^2=CD \cdot BD[/tex]

[tex]AD=\sqrt{CD \cdot BD}[/tex]

In this question, you are clearly supposed to use the geometric mean theorem or known as the right triangle altitude theorem. But note that there are other approaches to find the height of the triangle.

Using Pythagorean theorem:

[tex]AD^2+CD^2=AC^2 \Rightarrow AD=\sqrt{AC^2-CD^2}[/tex]

Also,

[tex]AD=AC\sin(c)[/tex]

Answer:

Let's say someone is selling lemonade at a lemonade stand. The more cups of lemonade this person sells, the more money they get. If 1 cup= $1, then he would get $2 for 2 cups.

Step-by-step explanation:

The price of the lemonade cup and the lemonade cup are a constant of proportionality. They are proportional to each other. The more lemonade you sell, the more money you get.

The graph would be a straight diagonal line. The y would be the money, and the x would be the amount of lemonade sold. Since they are the same and proportional, they would go in a straight line.

Step-by-step explanation:

Using factoring group to factor the polynomial 8x²y−10xy²+12x−15y

Step 1: Group the polynomial function

(8x²y−10xy²)+(12x−15y)

Step 2: Factor the common value and variables from the functions in parentheses.

= (2xy*4x - 2xy(5y)) + (3(4x) - 3(5y))

= 2xy(4x-5y)+3(4x-5y)

Step 3: Rearrange the expression by selecting one of the function in parentheses and combine those not in parenthesis.

(2xy+3)(4x-5y)

The final expression gives the factor form of the polynomial.

What is the domain and range of each relation?



Drag the answer into the box to match each relation.

{(−7, 2), (−2, 2), (0, 1), (4, 5)}


A mapping diagram. Element x contains negative 4, negative 3, negative 1, and 1. Element Y contains negative 3, negative 1, and 4. Negative four maps to negative 1. Negative three maps to negative 3 and 4. Negative one maps negative 1. One maps to 4.

Answers

Answer:

See below.

Step-by-step explanation:

The domain of a relation are simply its x-values, while the range of a relation are its y-values.

1)

We have the relation:

{(-7,2), (-2,2), (0,1), (4,5)}

Again, the domain of this relation are the x-values. Therefore, the domain is:

{-7, -2, 0, 4}

The range of this relation are the y-values. Therefore, the range is:

{2, 1, 5}

Note that even though the 2 repeats, we only count it once because it's the same.

2)

We have the relation:

{(-4,-1), (-3,-3), (-3,4), (-1,-1), (1,4)}

The domain are the x-values. Therefore, the domain is:

{-4, -3, -1, 1}

Again, the -3 repeats so we only count it once.

And the range would be the y-values:

{-3, -1, 4}

It's customary to place them in ascending order.  

Answer:

If there are two set A and B. All the elements of set A are called domain and all elements of set B are range.And element of B which are maping with set A elements are codomain

Step-by-step explanation:

domains are -7,-2,0,4

range are 2,1,5

Mrs. Lobo earns a salary of $50,000 per year plus a 4% commission on her sales. The average price of a share
she sells is $50.
Write an inequality to describe about how many shares Mrs. Lobo must sell to make an annual income of at
least $70,000
Select one:
O a. 50,000 + 2x > 70,000
O b. 50,000 + 2x < 70,000
O c. 50,000 -- 2x > 70,000
d. 50,000 + 2 > 70,000

Answers

Answer:

a) 50,000 + 2x > 70,000

Step-by-step explanation:

Mrs. Lobo has an annual salary of $50000 per year plus 4% commission on her sales.

If she makes $y commission from sales, Mrs Lobo total income per year is:

$50000 + $y.

She makes 4% commission on her sales of share with the average price of a share = $50

Average commission from sales = 4% × $50 = 0.04 × 50 = $2

If she sales x shares in a year, her commission would be $2x for the year. Therefore her total income for that year would be:

50000 + 2x

The amount of shares Mrs Lobbo must sell to make an annual income of at

least $70,000 is given by the inequality:

50,000 + 2x > 70,000

How to determine the type of the number

From the question, we have the following parameters that can be used in our computation:

The square root of the number 34

When evaluated, we have

The square root of the number 34 = √34

So, we have

The square root of the number 34 = 5.83.....

What is the middle term of the product of (x - 4)(x - 3)?

Answers

Answer:

- 7x

Step-by-step explanation:

Given

(x - 4)(x - 3)

Each term in the second factor is multiplied by each term in the first factor, that is

x(x - 3) - 4(x - 3) ← distribute both parenthesis

= x² - 3x - 4x +  12 ← collect like terms

= x² - 7x + 12

with middle term = - 7x

Answer:

Step-by-step explanation:

= x(x-3) - 4(x-3)

= x²-3x - 4x + 12

= x² -7x +12

So -7x is the middle term

what is the nth term of this sequence 7, 9, 11, 13

Answers

Answer:

The nth term of the sequence is

5 + 2n

Step-by-step explanation:

The sequence above is an arithmetic sequence

For an nth term in an arithmetic sequence

A(n) = a + ( n - 1)d

where a is the first term

n is the number of terms

d is the common difference

From the question

a = 7

d = 9 - 7 = 2 or 11 - 9 = 2

So the nth term for the sequence is

A(n) = 7 + ( n - 1)2

= 7 + 2n - 2

A(n) = 5 + 2n

Several theories have been put forward explaining the motive behind the accusations: Economic Causes In Salem, some families were very rich, while others were poor. This disparity led to jealousy among some of the people. Several families were engaged in property disputes. Some of the accused were rich. If convicted, they would lose their land and property, which could then be bought by others. Suggesting that a person was a witch was one way of obtaining that persons property. Some of the accused were poor. They were outsiders, and wealthier townspeople looked down on them. Accusing these people of being witches was one way of eliminating them from the village. Political Causes In the recent past, there had been several disputes over who should govern the Massachusetts Colony. The colonists had also endured some violent conflicts with American Indians. These events created political turmoil and instability. People were upset, and they blamed their problems on a lack of effective leadership. The leaders, in turn, were eager to see others take the blame for social problems. Accusing people of witchcraft made the accused responsible for social and political problems. The supposed witches could be blamed for whatever was wrong with society. Leaders did not have to take responsibility for mistakes or try to make changes. Intellectual Causes People knew little about science in those days. They were afraid of things they didnt understand. People didnt know about the causes of disease. If a person became sick, they believed it might be because of a curse. Witchcraft was one way of explaining the unknown. Psychological Causes Most of the accusers were young women and girls. At that time, girls were supposed to be quiet and obedient. They had little power in society. Accusing others of witchcraft may have made them feel powerful. Some girls and women may have been under pressure to make up stories about witchcraft. Powerful people who had something to gain from seeing certain people in the town convicted of witchcraft may have pressured these women into testifying. Mass hysteria may have also played a role. Mass hysteria happens when large numbers of people respond to real or imagined threats in an emotional and unreasonable way. They become frightened, angry, and even violent. During times of mass hysteria, people may engage in mob violence, hunting down, shaming, and sometimes even killing those they believe are responsible for their troubles. The power of suggestion can contribute to mass hysteria. When one person claims to see, hear, or feel something, others may believe it to be true and swear they hear, see, or feel the same thing without knowing why. For instance, if you see your friends scratch themselves or yawn, you may start scratching or yawning too, even if you arent itchy or tired. This is one example of what psychologists call the power of suggestion. Review this source for additional information about the causes of the Salem witch trials: Causes for the Outbreak of Witch Hysteria in Salem Think about the different theories that have been presented so far. Do you feel that one theory is more convincing than the others? Do you believe there might be more than one cause involved?
