The complex zeros of the polynomials are 20i and -20i
Given the polynomials, the zeros of the polynomial are gotten by equating the function to zero and then factorizing as shown:
f(x)=x^3−96x^2+400
x^3−96x^2+400 = 0
x^2(x-96) + 400 = 0
x^2(x - 96) = -400
x^2 = -400
Get the required complex roots:
x^2 = -400
x = ±√-400
x = ±20i
Hence the complex zeros of the polynomials are 20i and -20i

necessary. Do not enter the units of measurement.
16 lb for $3.99
Answer:
$4.1
Step-by-step explanation:
To find the Unit Rate, you have to find how much it cost of 1 lb. So, you have to divide 16 and 3.99
16/3.99
= 4.01002506

This is a triangle:
Answer:
v = 13
General Formulas and Concepts:
Pre-Algebra
Equality PropertiesGeometry
All angles in a triangle add up to 180°Step-by-step explanation:
Step 1: Set up equation
54 + 61 + 5v = 180
Step 2: Solve for v
Combine like terms: 115 + 5v = 180Subtract 115 on both sides: 5v = 65Divide 5 on both sides: v = 13And we have our final answer!
Answer:
13°
Step-by-step explanation:
Neccessary information:
Total internal angles in a triangle is equal to 180°.
Method:
The first step is to add the given values of 54 and 61, this gives you 115. This is because the total internal angle in a triangle is 180°. This means that in order to work out the value of v we must add the given values to find how much of the 180° is already known.
The next step is to find the value of 5v. This can be done by subtracting 115 (Total of the values given) from 180, this gives you 65(5v). This is because we are finding how much of the 180° total is not known.
The final step is to divide the value of 5v which is 65 by 5, this gives you 13. This is because 65 is equal to 5v so to work out the value of v you would need to divide by 5.
Step by step:
1) Add 54 and 61.
[tex]54+61=115[/tex]
2) Subtract 115 from 180.
[tex]180-115=65[/tex]
3) Divide 65 by 5.
[tex]65/5=13[/tex]

A department store buys 300 shirts for a total cost of 7,200 and sells them for $30 each. Find the percent markup.
Step-by-step explanation:
7200 ÷ 300 = 24
30 - 24 = 6
6/24 × 100/1 = 25%
The markup percent of 300 shirts is 25%.
What is Markup price?Markup price is defined as the difference of the selling price and the cost price of a product.
Markup percent can be found as,
Mark up % = profit / cost price × 100.
Given that,
The cost price for 300 shirts is 7200.
And, the selling price for each shirt is $30.
Then the selling price for all 300 shirts is 300 × 30 =$9000.
The markup percent can be found by taking the ratio of the difference of the selling and cost price to the cost price and then multiplying it by 100 as below,
Mark up percent = (Selling price - Cost price)/ Cost price × 100%
= (9000 - 7200) / 7200 × 100%
= 1 / 4 × 100%
= 25%
Hence, the percent markup is 25%.

Please help me get the answer
Answer:
b = 40°
Step-by-step explanation:
Since PQ = RQ, then Δ PQR is isosceles
Thus the 2 base angles are congruent
∠ PRQ = 180° - 140° = 40° ( adjacent angles are supplementary )
Then
∠ QPR = ∠ PRQ = b = 40°
Answer:
40 degrees
Step-by-step explanation:
The image says that PQ=RQ which makes this triangle isosceles. To solve you must remember that in isosceles triangles the two base angles are always congruent. In this case, the two bottom angles are the bases. So we must first solve for m<QRP. To do this use complementary angles to make the equation m<QRP=180-140. So m<QRP=40 which means b=40 also.

Answer:
y = 2.5x
Step-by-step explanation:
All of the other ones don't work but this one does.
(keep in mind that all of the numbers on the right side are the x)
Ex.
6 x 2.5 = 15
8 x 2.5 = 20
10 x 2.5 = 25
12 x 2.5 = 30
Hope this helps and have a great day!
Answer: I am assuming that x is the first column and y is the second column.
You are looking for an equation that works with every pair. I.e., when you plug in x, you get the y that is next to it. The only one that works is y = 2.5x.
Step-by-step explanation:
The first answer is obviously incorrect, because the y values are all larger than the x values, and if you multiply a number by .4, you will get a smaller number, not a larger one.
The second one works for every pair:
2.5(6) = 15, 2.5(8) = 20, 2.5(10) = 25, and 2.5(12) = 30.
The third one works for the first pair of numbers, but only for that one.
The last possibility doesn't work for any of them, and like the first answer, obviously gives a smaller y for each x, so cannot be the right answer.

Solve the function below for y when x=12
Answer:
y = -8
Step-by-step explanation:
2y=-3x+20
2y=-3(12)+20
2y=-36+20
2y=-16
y=-8
Answer:
y = -8
Step-by-step explanation:
2y = -3x + 20
2y = -3(12) + 20
2y = -36 +20
2y = -16
y = -16/2
y = -8
