Which coordinate is a zero of the function defined by 3x^2 – 15x – 18?

The given function is tan (0+24°) and its cofunction can be expressed as ;tan (0+24°)=  tan (66⁰-0)

Therefore tan (0+24°) in terms of its cofunctions, we need to use the formulas for sin and cos of complementary angles.

The complementary angle of 24° is 66° because 24° + 66° = 90°.

Using the formula for the sum of two angles, we can then substitute these values to get:

tan (0+24°)=  tan (66⁰-0)

Therefore, expression of tan (0+24°)in terms of its cofunctions is tan (0+24°) =  tan (66⁰-0)

The measure of angle a is 35°

The chord of a circle is the line segment joining any two points on the circumference of the circle.

The diameter is the longest chord of a circle which passes through the center of the circle.

For chords that meet inside of a circle, the measure of the angle formed is one-half the sum of the measure of the arcs intercepted by the angle and its vertical angle.

Using the above concept (That is the given hint in the question), we can say:

∠a = (29 + 41)/2

∠a = 70/2

∠a = 35°

Therefore, the measure of angle a is 35°

Answer:

The list of rational numbers below are ordered from greatest to least.

15, 6.7, , 100%, -55%,

To determine which of the following numbers could NOT be the missing value in the list above, we need to determine the correct order of the numbers in the list.

First, we can convert the percentages to decimals:

100% = 1

-55% = -0.55

Now we can order the numbers from greatest to least:

15, 6.7, 1, -0.55, x

We know that x is a rational number, so it can be expressed as a fraction. We can eliminate answer choices C and D because they are not rational numbers.

Next, we can compare x to the other numbers in the list. We know that x must be less than 6.7, so we can eliminate answer choice A.

That leaves us with answer choice B, -2.5. This number could be the missing value in the list, so the answer is B.

the unit rate is 4 meters per second, meaning that for every second that passes, the distance increases by 4 meters.

The table shows the relationship between time and distance time is measured in seconds and distance is measured in meters.

The table provides us with the data points of time and distance allows us to examine the relationship between these two variables.

The table as time increases the distance also increases.

This suggests that there is a positive relationship between time and distance.

The unit rate of the relationship tells us how much distance changes for every unit of time.

The unit rate is 4 meters per second meaning that for every second that passes, the distance increases by 4 meters.

The relationship shown in the table is not necessarily a linear relationship.

A linear relationship would mean that the distance changes by the same amount for each unit of time.

The increase in distance is not constant over time.

From 5 seconds to 10 seconds the distance increases by 20 meters but from 10 seconds to 15 seconds the distance increases by 20 meters again and from 15 seconds to 20 seconds the distance increases by 20 meters yet again.

The table provides us with a snapshot of the relationship between time and distance and by examining the data we can identify patterns and relationships that can help us understand the behavior of these variables.

The probability that at least one barrel develops a leak over a 20-year period is approximately 0.1813 or 18.13%.

Since leaks in different barrels are independent, the probability that none of the 10,000 barrels develops a leak in a given year is:

0.99999¹⁰⁰⁰⁰ = 0.9048

Therefore, the probability that at least one barrel develops a leak in a given year is:

1 - 0.9048 = 0.0952

Now we can use the same approach to find the probability that no barrel develops a leak in 20 years:

0.99999²⁰⁰⁰⁰⁰ = 0.8187

The fraction of the wall that is concrete is 12/19

A fraction is a mathematical representation of a part of a whole or a division of one quantity by another. It consists of two parts: a numerator and a denominator, separated by a horizontal line called a fraction bar or a division slash.

The numerator represents the number of parts or the quantity being considered, while the denominator represents the total number of equal parts or the divisor. The numerator and denominator are both whole numbers or integers.

In this problem, to determine the fraction that is concrete, we have to know the total length of the wall.

length of wall = 24 + 5 + 9 = 38 inches

The fraction of the wall that is concrete = 24 / 38 = 12/19

The tax deduction is explained below.

We need to take into account a few things in order to establish how much, if any, of the $1,000,000 loss Ethan may deduct in the current year.

We need to know Ethan's basis in his ELS shares, or shareholder basis. Shareholder basis, which is changed yearly based on numerous criteria such as income, losses, donations, and payouts, symbolizes the investment a shareholder has in the S corporation.

Ethan might be entitled to deduct the loss up to the amount of his basis if his basis is positive.

We must assess if Ethan is covered by the at-risk regulations. The shareholder's amount at risk in the S corporation is the only amount that can be deducted for losses under the at-risk regulations.

If Ethan is subject to these rules, his loss deduction could be limited based on his at-risk amount.

A few tax provisions were temporarily changed as a result of the CARES Act. The CARES Act specifically altered the exclusions for business losses for non-corporate taxpayers, including individual S company shareholders. Ethan might not be able to deduct the $1,000,000 loss because of restrictions on company losses that existed prior to the CARES Act.

The excess business loss limitation for non-corporate taxpayers was temporarily suspended under the CARES Act.

This meant that Ethan and other individual shareholders could write off business losses without being constrained by the prior cap of $250,000 ($500,000 for married taxpayers filing jointly).

Therefore, regardless of any restrictions that could have existed before to the passage of the CARES Act, Ethan would be permitted to deduct the entire $1,000,000 loss in the current year if the CARES Act is applicable.

Taxpayers were temporarily helped by being able to deduct losses from other income. It's crucial to remember that the CARES Act was passed in reaction to the COVID-19 outbreak and that some of its requirements could not be in force at the moment.

Answer:

Step-by-step explanation:

To find the profit as a percentage of the cost price, we need to calculate the profit first.

Profit = Selling price - Cost price

Profit = #540,000 - #450,000

Profit = #90,000

Now we can calculate the profit percentage as follows:

Profit percentage = (Profit / Cost price) x 100

Profit percentage = (#90,000 / #450,000) x 100

Profit percentage = 20%

Therefore, the profit as a percentage of the cost price is 20%.

Answer:

$690

Step-by-step explanation:

To find the interest earned in three years, we can use the interest formula

Interest = Principal x Rate x Time

- Principal = $600 (the amount John deposited)

- Rate = 5% per year (as a decimal, this is 0.05)

- Time = 3 years

Interest = $600 x 0.05 x 3 = $90

Therefore, John will earn $90 in interest over 3 years.

To find his account balance, including interest, after 3 years, we can simply add the interest earned to the original principal:

Account balance = Principal + Interest

Account balance = $600 + $90 = $690

Therefore, John's account balance, including interest, after 3 years will be $690.

Answer:

Simple interest: 690, compound interest: 694.5

Step-by-step explanation:

Simple interest  = PRT/100 = 600*5*3/100 = 90 = 600+90 = 690

compound interest = P(1+r/100)^n = 600(1+5/100)^3 = 694.5

Monday          | 70%

Tuesday         | 10%

Wednesday    | 40%

Thursday        | 50%

Friday             | 60%

According to the table, Monday has the highest chance of rain with a probability of 70%. This indicates that there is a relatively high likelihood of rain occurring on Monday. However, it does not guarantee that it will rain, as there is still a 30% chance of a dry day.

On Tuesday, the chance of rain drops significantly to 10%. This suggests that it is highly unlikely for rain to occur on Tuesday, with a higher probability of dry weather.

Wednesday shows a moderate chance of rain at 40%. This indicates a somewhat higher possibility of precipitation compared to Tuesday but not as high as Monday.

Thursday follows with a 50% chance of rain. This suggests an even chance of rain or no rain, making it relatively uncertain.

Finally, Friday has a 60% chance of rain. This indicates a relatively high probability of rainfall, making it more likely to experience wet conditions on Friday.
