The ground temperature at an airport was 10 degree temperature dropped 5 degrees for every 1000m above the ground. What was the temperature outside an airport that took off from this airport and climbed to 5000m?



PLZ EXPLAIN ANSWER IN DETAIL

Answers

Answer 1
The ground temperature started at 10 degrees.
The rate was: for every 1000 meters (m) of going above the ground, the temperature dropped 5 degrees, meaning that it got cooler.
The ratio is 1000 meters to 5 degrees
So that would mean: 10-5-5-5-5-5=-15 degrees

Answer 2

The temperature at 5000m is -15 degrees Celsius.

To determine the temperature outside an airplane that has climbed to an altitude of 5000m, we start with the initial ground temperature at the airport, which is 10 degrees Celsius. For every 1000m increase in altitude, the temperature drops by 5 degrees Celsius. We can calculate the temperature decrease over 5000m by multiplying the temperature change per 1000m (5 degrees) by the number of 1000m segments in 5000m (which is 5).

The calculation is as follows:

Temperature drop per 1000m = 5 degrees Celsius

Number of 1000m segments in 5000m = 5

Total temperature drop = 5 segments * 5 degrees/segment = 25 degrees Celsius

Temperature at 5000m = Ground temperature - Total temperature drop

Temperature at 5000m = 10 degrees Celsius - 25 degrees Celsius

Temperature at 5000m = -15 degrees Celsius

Therefore, the temperature outside an airplane that climbs to an altitude of 5000m is -15 degrees Celsius.

Mariana graphs the function ƒ(x) = x3 − 4x2 − 3x + 18 and sees two zeros: −2 and 3. Since this is a polynomial of degree 3 and she only sees two zeros, she determines that the Fundamental Theorem of Algebra does not apply to this equation. Is Mariana correct? Why or why not?

Answers

Answer:

No, the root 3 has multiplicity of 2.

Final answer:

Mariana is incorrect because the Fundamental Theorem of Algebra states that a third-degree polynomial must have three complex roots, and she has found only two real zeros.

Explanation:

Mariana is not correct in her assumption that the Fundamental Theorem of Algebra does not apply to the function ƒ(x) = x^3 − 4x^2 − 3x + 18. The Fundamental Theorem of Algebra states that every non-constant single-variable polynomial with complex coefficients has at least one complex root. This theorem guarantees that a polynomial of degree n has exactly n complex roots, though some of the roots may be repeated and not all of them may be real. In Mariana's case, the polynomial is of the third degree, so it should have three complex roots. She has found two real zeros, −2 and 3. There must be another root, which could also be real or complex. If all roots were real, she would see all three zeros on the graph. If the third root is complex, it will not appear on the real number graph that Mariana is using.

3/5 of a fence was installed in 1 1/2 days. how many days to install the whole fence?

Answers

First, let's convert the mixed number 1 1/2 to the improper fraction 3/2. We're given that it takes 3/2 days to install 3/5 of a fence. We're looking for how long it takes to install one whole fence - or 5/5 of a fence. To determine that, let's first find out how long it takes to install 1/5 of a fence, and then multiply that quantity by 5 to obtain our answer.

If it takes 3/2 days (3 half-days) to install 3/5 of a fence (3 fifths of a fence), then it makes sense that it would take 1/2 day (1 half-day) to install 1/5 of a fence (1 fifth of a fence).

If it takes 1/2 day to install 1/5 of a fence, then it should take 5 times that amount of time to install all 5/5 of it, or 5 * (1/2) = 5/2 days, or 2 1/2 days as a mixed number.
It will take 2 1/2 days to install the whole fence

At 1 pm, there were 16 seagulls on the beach. At 3 pm, there were 40 seagulls. What is the constant rate of change?

Answers

The answer is (change of amount) / (change of time). For the change of amount, the numerator is 40 seagulls - 16 seagulls, leaving a total of 24 seagulls. For the change of time, the denominator is 3 pm - 1 pm, leaving a total of a 2 hour difference. The answer becomes 24 seagulls / 2 hours, or 12 seagulls per hour when simplified.

What's the absolute value of f(x) = x - 2

Answers

an absolute value is how far the answer is from zero. I am not totally sure what the answer is but that is all I know. My guess is      l f(x) = x-2 l
Would anyone like to add on to that?
Keep in mind that the absolute value function has two conditions in its definition: |x| = x if x >= 0, and |x| = -x if x < 0. This ensures that the output of |x| is always positive by negating any potential negative values of x.

So, the absolute value of f(x), |x - 2|, will have two possible values:

x - 2, when x - 2 >= 0, and
-(x - 2) = -x + 2, when x - 2 < 0.

since they want to make 1 1/2 of the recipe that means that it is half of the recipe three times so you need to multiply 5/16 by three

For the second one, they are wanting to make 1 and 1/2 the original recipe. This means it is a 50% increase from the original recipe. So, we should multiply 1 and 1/2 by 5/8.

What is the answer cause I have having trouble knowing if it was right

Answers

How to find each one: So first, if you have a fraction, (you probably want to simplify the ones you've put in by dividing both sides by the same number, for example, 45/100, both sides by 5, 9/20)

So if you have a fraction: 

You can find the ratio by just putting the numerator on the left, n:, and the denominator on the right. n:d

For example, with 5/9, 5:9.

For decimal, you can just divide. For example, 4/5, 0.8. 

Percent, just change the decimal to have a hundredths place, with 0.8, 0.80, and then just take those two digits, or 80%.

So basically, for ratio, you can do it if you have the fraction.

For the column fraction, if you know basic fractions, you can also convert from those, and also from the ratios.

For decimal, if you know percent or fraction, you should be able to find it.

Percent, fraction or decimal should work.

I'll do a row to explain, it's kind of confusing, sorry:

So if you have 9:20, you can convert that to the fraction, 9/20.

Then you can find the decimal, 9/20 = 0.45

Percent would therefore be 45%.

Hope this helped :)

What’s 40% in fraction

Answers

40% in a fraction is 2/5 it is also 0.4 in a decimal if you're curious 

To write a percent as a fraction in lowest terms, we need to remember that a percent is a ratio that compares a number to 100.

40% can be written as the ratio [tex]\frac{40}{100}[/tex]. [tex]\frac{40}{100}[/tex] is not in lowest terms so we need to divide the numerator and the denominator by 20 which gives us [tex]\frac{2}{5}[/tex].

Therefore, 40% can be written as the fraction [tex]\frac{2}{5}[/tex].

what is -4/5 + 3/20 in simplest form

Answers

-4/5 = -16/20, so the new expression is (-16/20)+(3/20)
then, -16 + 3 is -13, so the solution is -13/20
-4/5 + 3/20 = 3/20 - 4/5

To subtract 2 fractions, they both need to have the same denominator.
Since 5 is one of the divisors of 20, we can just multiply the numerator and denominator of 4/5 by 4.
4/5 = (4*4) / (5*4) = 16/20

P.S. when the denominators of both fractions don't have any relation, you multiply the numerator and denominator of the first fraction by the denominator of the second, and the numerator and denominator of the second by the denominator of the first.

3/20 - 4/5 = 3/20 - 16/20

Now you just subtract the numerators:
3/20 - 16/20 = (3-16)/20 = -13/20

So -4/5 + 3/20 = -13/20
