In the following diagram, HI is parallel to JK. What is the measure of x?

Answer:

Step-by-step explanation:

14) Amount in Harper's school lunch account = $ 75

Cos of one meal = $ 3.25

Cost of 'm' meals = 3.25 * m = 3.25m

Balance amount in Harper's account after getting 'm' meals = $ 19.75

Total amount - Cost of 'm' meals = 19.75

      75 - 3.25m = 19.75

         To find the value of 'm', isolate m. To isolare m subtract 75 from both sides

             -3.25m = 19.75 - 75

             -3.25m  = -55.25

Now divide both sides by (-3.25)

                     m = -55.25/(-3.25)

m = 17

15) Starting height = 24 ft

Height after t seconds = 4.5*t = 4.5t

To see the river, the drone should reach the height atleast 330 ft above the ground. ⇒ It should be at the height greater than or equal to 330 ft

Initial height + height after 't' seconds ≥ 330

24 +  4.5t ≥ 330

Subtract 24 from both sides

          4.5t ≥ 330 - 24

          4.5t ≥ 306

Divide both sides by 4.5

    t ≥ 306/4.5

     t ≥ 68

He will be able to see the river from 68 seconds ( 1 minute 8 seconds)  and above.

No, Imani will not be able to the river after the drone has been raising  for one minute. At 1 minute 8 seconds Imani will start seeing the river. So at one minute, the drone will not have reached the required height .

Answer:

12x^3 + 19x^2 + x - 5

Step-by-step explanation:

To solve this, I set up the problem like this:

(3x^2 + x - 1)(4x + 5)

Now, just distribute everything from the first set of ( ) to the second set of ( ). Here's what you should have when you do that:

12x^3 + 15x^2 + 4x^2 + 5x - 4x - 5

Now, you would just combine like terms, which would get you to the final answer.

Hope this helps!

12x³ + 19x² + x -5

Polynomials are expressions that have multiple terms.

Breaking Apart Polynomials

When multiplying by a polynomial, we can break apart one of the polynomials, and multiply by each term individually. This means to multiply 3x² + x - 1 by 4x + 5, we can break apart the binomial into its separate terms. Instead of trying to multiply everything at once, we can multiply the trinomial by 4x and then multiply the trinomial by 5. Finally, add together the 2 products for the final answer.

Multiplying Polynomials

First, let's multiply the trinomial by 4x.

To find the product, multiply each term of the trinomial by 4x, then add them back together.

So, the first product is 12x³ + 4x²- 4x. Next, let's multiply 5(3x² + x - 1) the same way.

This means that the second product is 15x² + 5x - 5. Finally, let's add the 2 products together.

Then, simplify the expression.

This gives us our final answer. The product of 3x² + x - 1 and 4x + 5 is 12x³ + 19x² + x - 5.

The probability that at least two of the balls have the same number is 27.40%

Probability is the function that measures the chances that an outcome of a random event will be as expected. In this way you can measure how likely it is that an event will happen.

Probability requested is equivalent to:

P(at least 2 have same number) = 1 - P(no 2 have the same number)

P(no 2 have same number) = No. of ways to succeed / No. of possible outcomes

No. of ways to succeed = 90P8

No. of possible outcomes = 90^8

No. of ways to succeed =

nPr = n! / (n-r)!

90P8 = 90! / (90-8)!

90P8 = 90! / (82)!

90P8 = 90*89*88*87*86*85*84*83*82! / [(82)!

90P8 = 90*89*88*87*86*85*84*83

90P8 = 3.13x10^15

P(no 2 have same number) = 3.13x10^15 / 90^8

P(no 2 have same number) = 0.73

P(at least 2 have same number) = 1 - P(no 2 have the same number)

P(at least 2 have same number) = 1 - 0.73

P(at least 2 have same number) = 0.2740 = 27.40%

The recursive sequence that produces the sequence 4, -6, 4 is:

4, -6, 4, -6, 4, ...

A function that refers back to itself is referred to as a recursive sequence. Here are a few recursive sequence examples. Because f (x) defines itself using f, f (x) = f (x 1) + 2 is an illustration of a recursive sequence.

To generate the sequence 4, -6, 4 using a recursive sequence, we can use the following formula:

\(a_n = a_{n-1} + (-1)^{n+1} * 10\)

where \(a_n\) is the nth term of the sequence.

Using this formula, we get:

\(a_1 = 4\\a_2 = 4 + (-1)^{2+1} * 10 = -6\\a_3 = -6 + (-1)^{3+1} * 10 = 4\)

Therefore, the recursive sequence that produces the sequence 4, -6, 4 is:

The answer based on debt to assets ratio for east and west company are,

East company debt to assets ratio is equal to 0.44.

West company debt to assets ratio is equal to 0.28.

After comparing both the company debt to assets ratio East company is at higher level of financial risk.

Assets = Liabilities + Equity

For East company,

206,000 =  91,000 + 115,000

Assets = 206,000

liabilities = 91,000

Equity = 115,000

For West company,

603,000 =  169,000 + 434,000

Assets = 603,000

liabilities = 169,000

Equity = 434,000

Debt-to-assets ratio = Total liabilities divided by the total assets.

Debt-to-assets ratio for East

= 91,000 / 206,000

= 0.44

Debt-to-assets ratio for West

= 169,000 / 603,000

= 0.28

Comparing the two ratios,

0.44 > 0.28

This implies,

Company East has a higher debt-to-assets ratio is greater than the compared to Company West.

This represents that Company East has a higher level of financial risk.

As larger proportion of their assets are financed through debt.

This shows it is difficult to repay if the company experiences financial difficulties.

Company West has a lower level of financial risk as smaller proportion of their assets are financed through debt.

Therefore, the answer of the following questions are,

Debt to asset ratio of east company = 0.44

Debt to asset ratio of west company = 0.28

Company east has a higher financial risk level .

The statement that best describes the Central Limit Theorem is (a) The distribution of means of random samples pulled from a population will be normally distributed if the sample size is large enough.

The Central Limit Theorem (CLT) states that if repeated random samples is taken from a population with a finite mean and standard deviation, then the distribution of the sample means will approach a normal distribution, even if the original population is not normally distributed.

The larger the sample size, the more closely the sample means will approximate a normal distribution.

which means that, for example, if we take multiple samples of size 100 from a population and calculate the average of each sample, the distribution of those sample means will be approximately normally distributed, regardless of the original shape of the population.

The given question is incomplete , the complete question is

Which best describes what the Central Limit Theorem states ?

(a) The distribution of means of random samples pulled from a population will be normally distributed if the sample size is large enough.

The difference of ladder slip is, 4 cm.

What is sliding down ladder?

A ladder can be quickly lowered by sliding down it. This function can keep the action going while descending a ladder and is present in many contemporary video games. Typically, a figure descends a ladder by placing their hands and feet on the exterior of the structure and letting themselves slide down it effortlessly.

Given: At the start of the day, a painter rested a 3 m ladder against a vertical wall so that the foot of the ladder was 50 cm away from the base of the wall.

During the day, the ladder slipped down the wall, causing the foot of the ladder to move 70 cm further away from the base of the wall.

Here 3m = 300 cm

So,

\(CE = \sqrt{BE^2-BC^2}= \sqrt{(300)^2-(50)^2} = 295 cm\)

\(DC = \sqrt{AD^2 - AC^2} = \sqrt{(300)^2-(70)^2}= 291cm\\\)

Hence, the difference of ladder slip is,

295 cm - 291 cm = 4 cm.

Answer:

x = 116

Step-by-step explanation:

The sum of the angles of a  4 sided polygon is 360

96+x+64+84 = 360

Combine like terms

x+244=360

Subtract 244 from each side

x+244-244=360-244

x = 116

Sum of all angles of a quadrilateral = 360°

So, 96° + 84° + 64° + x° = 360°

=> 244° + x° = 360°

=> x° = 360° - 244°

=> x° = 116°

=> x = 116

The phasor representation of the given current expression is i = 150√2e²(j200t) + 50je²(j200t)

To find the phasor representation of the given current:

i = [300cos(200t + 45°) - 100sin(200t - 30°)]A

the current expression in terms of a phasor notation using Euler's formula:

i = Icos(ωt + θ) + jsin(ωt + θ)

Where:

I is the amplitude of the current,

ω is the angular frequency,

t is time,

θ is the phase angle,

j is the imaginary unit (j² = -1).

Comparing this form to the given expression,

Icos(ωt + θ) = 300cos(200t + 45°)

jsin(ωt + θ) = -100sin(200t - 30°)

From the first equation identify:

I = 300

θ = 45°

ωt = 200t

From the second equation identify:

I = 100

θ = -30°

ωt = 200t

To convert the given expressions into the phasor notation combine the real and imaginary parts:

i = (Icosθ + jIsinθ)e²(jωt)

For the first term:

Icosθ = 300cos(45°) = 300 × (√2/2) = 150√2

For the second term:

jsinθ = -100sin(-30°) = -100 ×(-1/2) = 50

Combining the real and imaginary parts,

i = (150√2 + 50j)e²(j200t)
