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.

Regarding the whole "explain using mental math" thing, I pretty much just used the fact that 8a. and 8b. both had the same number of decimal places. For 8c., I just made each number have a denominator of 10. And last, for 8d., all of the denominators were already the same, which made it pretty easy.

fred got a score of 84 on the test. write a division sentence using negative integers where the quotient represents the number of questions fred answered incorrectly
Answers
We are given that:
>perfect score- 100
>number of questions of the test- 25
>worth of each question- 4 points
>Fred's score- 84
Let us say that n- number of questions Fred answered wrong
The solution:
let us solve for n
>division sentence: (100 ÷ 4 ) - ( 84 ÷ 4 ) = n
(100 ÷ 4 ) - ( 84 ÷ 4 ) = n
25 - 21 = n
4= n
Therefore Fred answered 4 test questions incorrectly.
Final answer:
To create a division sentence expressing the number of incorrect answers as a negative integer, you would divide the total number of questions by -0.16. This implies that Fred answered 16% of the questions incorrectly.
Explanation:
To write a division sentence using negative integers where the quotient represents the number of questions Fred answered incorrectly, we need to first determine the total number of questions on the test. We can assume that a perfect score is 100%. If Fred scored an 84, that implies he got 84% of the questions correct. We do not know the total number of questions, so let's denote the total number as x.
Since Fred got 84 out of 100 percent, that means he answered 16% of the questions incorrectly. In terms of the total number of questions x, he answered 0.16x questions incorrectly. Since he answered these questions incorrectly, and incorrect answers are considered as losses or negatives, we can multiply the total number of questions x by -0.16 to find the number of questions he answered incorrectly. Therefore, the division sentence could be -x/(-0.16) = y, where y represents the number of questions Fred answered incorrectly.

From the unit circle, we can check that [tex]\sin30^{\circ}[/tex] and [tex]\sin(-30)^{\circ}[/tex] have the same value, but opposite signs, that is:

What’s 40% in fraction
Answers
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].

3/5 of a fence was installed in 1 1/2 days. how many days to install the whole fence?
Answers
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.
what is -4/5 + 3/20 in simplest form
Answers
then, -16 + 3 is -13, so the solution is -13/20
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

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