Write A Two Column Proof

Answers

Answer 1
We are given intersecting lines. The measures of a pair of angles forming vertex angles, are 2x+6° and 96°.

The measure of 2 vertex angles is equal, so we solve the equation:

2x+6°=96°, subtract 6° from both sides of the equation
2x=90°,   divide both sides of the equation by 2
x=45°

Brianna bought a new car for $15000. Each year the value of the car deprecaites by 30% of its value of the previous year. In how many years will the car be worth only $500?

Answers

The formula is
A=p (1-r)^t
A future value 500
P current value 15000
R rate of depreciation 0.3
T time?
500=15000 (1-0.3)^t
Solve for t
Divide both sides by 15000
500/15000=(1-0.3)^t
Take the log for both sides
Log (500/15000)=t×log (1-0.3)
Divide both sides by log (1-0.3)
T=(log(500÷15,000)÷log(1−0.3))
T=9.5 years round your answer to get 10 years

Hope it helps!
A = P(1+r%)ⁿ , where P = initial value, A= new value, n = number of years and
r% is the growth or depreciation rate, depending on its sign:
If it's a depreciation, the formula becomes:

A = P(1 - r%)ⁿ

500 = 15000(1-0.3)ⁿ

500/15000 = (0.7)ⁿ

0.033333 = 0.7ⁿ


ln(0.03333) = n.ln(0.7)

n = ln(0.03333)/ln(0.7)

n = 9.5 years

Choose all the sets containing the number Pi:

natural numbers

whole numbers

integers

rational numbers

irrational numbers

real numbers

Answers

Answer:

The set containing Pi is:

Irrational numbers.Real numbers.

Step-by-step explanation:

We have to classify the number "pi" or π.

We know that:

Pi is the ratio of a circumference of a circle to it's diameter.

Pi is an irrational number i.e. it could not be represented in the form of p/q where p is an integer and q is a natural number.

However we sometimes take pi to be 22/7 ; but it's not exactly the same it's just a close approximation.

Hence, we may classify Pi as:

Irrational number.

Also irrational number comes in the category of real numbers.

Hence, Pi is also a real number.

( As real numbers are divided into two category:

1.  Rational  number

2. Irrational number

Also Rational number contains whole numbers, integers and whole numbers)

Using the number sets, the correct options are:

irrational numbers  real numbers

-------------------------------------

Whole numbers: Set of numbers including all positive numbers and 0, so: {0,1,2,...} Integer numbers: Number without decimals, that can be positive of negative, so: {...,-2,-1,0,1,2,....} Rational numbers: Integer plus decimals that can be represented by fractions, that is, they either have a pattern, or have a finite number of decimal digits, for example, 0, 2, 0,45(finite number of decimal digits), 0.3333(3 repeating is the pattern), 0.32344594459(4459 repeating is the pattern). Irrational numbers: Decimal numbers that are not represented by patterns, that is, for example, 0.1033430290339. Real numbers: Rational plus irrational.

-------------------------------------

The number [tex]\pi = 3.1415...[/tex] is a decimal number without repetition, that is, it has infinite decimal places, thus it is irrational.Irrational numbers are also real.Thus, the correct options are irrational and real.

Suppose that there are eight corporations competing for nine different contracts. If the contracts are awarded randomly, what is the probability that each corporation will get at least one contract?

Answers

Final answer:

To find the probability that each corporation will get at least one contract out of eight corporations competing for nine different contracts, we can use the concept of permutations and the principle of inclusion-exclusion.

Explanation:

To find the probability that each corporation will get at least one contract, we can use the concept of permutations. Since there are 8 corporations and 9 contracts, we can calculate the total number of ways to assign the contracts to the corporations without any restrictions, which is 9! (9 factorial).

Next, we need to find the number of ways that each corporation gets at least one contract. This can be calculated using the principle of inclusion-exclusion. We subtract the number of ways that at least one corporation doesn't get a contract from the total number of permutations.

The number of ways that at least one corporation doesn't get a contract can be calculated by assigning 9 contracts to 7 corporations, which is 7! (7 factorial).

Finally, we can calculate the probability by dividing the number of ways that each corporation gets at least one contract by the total number of permutations:

Probability = (9! - 7!) / 9!

Answers

Answer-

The sequences of transformations that maps △ABC to △A′B′C′ are

Reflection across the y-axisTranslation 2 units left

Solution-

The coordinates of the vertices of ΔABC are

A = (−4, 6)

B = (−2, 2)

C = (−6, 2)

The coordinates of the vertices of ΔA′B′C′ are

A′ = (2, 6)

B′ = (0, 2)

C′ = (4, 2)

As all the y-coordinates of all the function are same, so the triangle is neither translated up or down (∵ (x, y) → (x, y±k)), nor reflected over x-axis(∵ (x, y) → (x, -y)).

As the signs of x-coordinate is changed, it might be reflected over y axis,

Rule for reflection over y axis is,

(x, y) → (-x, y)

so,

A" = (4, 6)

B" = (2, 2)

C" = (6, 2)

As the x-coordinates of vertices of ΔA′B′C′ are 2 units less than that of ΔA"B"C"

So it is then translated 2 units left.

Therefore, the sequences of transformations that maps △ABC to △A′B′C′ are

If jay ran 1 mile in 5 minutes on monday, 2 miles in 10 minutes on tuesday, and 3 miles in 15 minutes on wednesday, how many miles do you think he might run in 20 minutes on thursday?

Answers

If Jay continues the same pattern of running an extra mile in the extra 5 minutes each day then on Thursday you would expect him to run 4 miles in 20 minutes

Answer:

Jay might run 4 miles in 20 minutes

Step-by-step explanation:

If Jay ran on Monday = 1 mile in 5 minutes

On Tuesday = 2 miles in 10 minutes

On Wednesday = 3 miles in 15 minutes

Jay is increasing his time by 5 minutes per day and distance 1 mile per day.

So the next day Jay might run 1 mile + previous day distance in 5 minutes + time of the previous day.

Therefore, Jay might run 4 miles in 20 minutes

Answer:

equation of circle (x +2)² + (x + 5)² = 16.

Step-by-step explanation:

Given : A circle has its center at (-2, 5) and a radius of 4 units.

To find  :  What is the equation of the circle.

Solution : We have given  center at (-2, 5) and radius = 4 units .

Standard form of circle : (x -h)² + (x + k)² = r²

Where, ( h, k) is center  , r = radius .

Plugging the values of h , k and r in standard  equation

(x -(-2))² + (x + 5)² = (4)²

(x +2)² + (x + 5)² = 16.

Therefore, equation of circle (x +2)² + (x + 5)² = 16.

Write an inequality that describes this graph.

Please explain HOW you got your answer, thanks a ton! :)

Answers

To find the inequality, we need to remember our rules about what makes inequalities from number lines.

If the "dot" (initial point) is hollow, it is simply a "<" or ">" symbol. If the "dot" is filled in, it means that it includes that number and we should use a "≤" or "≥" symbol. In this case, our "dot" is filled, so we will be using a "≤" or "≥" symbol.

The second rule we must recall is that the "arrow" (symbol) points the direction that the line will go. In this case, our line is going left, so our "arrow" should point left (≤).

Using all of the logic above, we would be able to see that x≤1.


Answer:

z ≤ 1

Step-by-step explanation:

We know the following:

If the initial point is colored, then the only possible inequality signs are ≤ or ≥. However, if the initial point is not colored, then the possible inequality signs for the inequality is < or >. If the line goes to the left of the initial point, it means that the initial point is greater than the numbers on the left of the initial point. If the line goes to the right of the initial point, it means that the initial point is less than the numbers on the right of the initial point.The inequality sign "≤" defines "less than or equal to"The inequality sign "≥" defines "greater than or equal to"The inequality sign "<" defines "greater than"The inequality sign ">" defines "less than"

We can observe that:

In the inequality, we can see that the initial point of the inequality is colored. Therefore, the possible inequality signs for the inequality shown on graph are ≤ or ≥. Let us start setting our inequality.

⇒ _ ≤ or ≥ _

We can see that the inequality line shown on the graph, goes to the left. Therefore, the line shown on the graph defines that the initial point is greater than the numbers on the left of the number line.

⇒ _ ≥ _

Since "1" is the initial point and is greater than or equal to the numbers on the inequality, we can put "1" on the L.H.S of the inequality. Now,

⇒ 1 ≥ _

[Optional] Write the numbers, that are less than 1, on the R.H.S of the inequality. Then, we get the following inequality:

⇒ 1 ≥ 0, -2, -4, -6...

[Optional] Include "1" in the series as ≤ means greater than or equal to.

11, 0, -2, -4, -6...

Let us assume that the numbers less than and equal to 1, be known as z.

11, 0, -2, -4, -6...⇒ 1z

Therefore, the inequality that represents the graph is z ≤ 1.
