*****Write a polynomial using the roots -3,5i. PLEASE HELP IM SO LOST!!!

Answers

Answer 1

Answer: The polynomial $(x-a)$ has a unique root, $a$ , for any $a$ .

Hence $(x+3)(x-5i)$ is a polynomial with roots $-3$ and $5i$

2/5 divided by 9/10A. 2/5

actually 0.00444444444 as a fraction

Answers

it would be D because when you divide fractions, you multiply by the reciprocal of the fractions so 2/5 * 10/9. Then you simplify and get 4/9. Hope this helps!!!!!!!

Answer:

1. 3 2/3

2. 4 9/10

3. 1 27/56

4. 58 2/15

5. 11 1/24

Step-by-step explanation:

1. To find the answer, add 3 1/6 and 5 9/10. First change them into improper fractions. 5 9/10 is 59/10 and 3 1/6 is 19/6. Now, you have to make the denominator (bottom number) the same number for both fractions. To do this you must find a LCM for both the number (10, 6) a LCM for these numbers is 30. Now to change the denominator to this you must times the numerator and denominator by the number needed to get the LCM for the denominator.

So 6 x 5 = 30 and 3 x 10 = 30.

19/6 x 5 = 95/30 and 59/10 x 3 = 177/30

Now add the fractions:

This equals 272/30

Simplify:

Now take 12 5/6 and turn it into a improper fraction: 77/6

Now again, you have to make the denominator to 30

77/6 x 5 = 385/30

Now subtract 385/30 - 272/30

This equals 113/30

Now turn this back into a mixed fraction:

3 23/30

The answer is 3 23/30

This process is basically the same for all the other questions.

In the rhombus, m1 = 18x, m2 = x + y, and m3 = 30z. Find the value of the variables x, y, and z. The diagram is not drawn to scale.

Answers

None of the angles are 90 degrees. The sides of the rhombus that are across from each other are parallel. would add up to 180 degrees, When we have a rhombus, that bit of info really helps.

Use quadratic regression to find a function that fits the following points. (-2,-16), (3,11), (0,2).

Answers

Answer:

y = -1.2x² +6.6x +2

Step-by-step explanation:

The quadratic regression function of a calculator or spreadsheet can do this for you. The resulting function is ...

y = -1.2x² +6.6x +2

_____

If you want to do this by hand, put the given (x, y) values into the formula ...

ax² +bx +c = y

and solve the resulting system of equations.

The third point tells you c=2, so you can simplify the system of equations to ...

a(-2)² +b(-2) +2 = -16 ⇒ 4a -2b = -18 ⇒ 2a -b = -9

a(3)² +b(3) +2 = 11 ⇒ 9a +3b = 9 ⇒ 3a +b = 3

Adding these equations together gives ...

(2a -b) +(3a +b) = (-9) +(3)

5a = -6 . . . . . . . . simplify

a = -1.2 . . . . . . . divide by 5

b = 3 -3a = 3 -3(-1.2) = 6.6 . . . . from the second equation

Now we know the coefficients are a=-1.2, b=6.6, c=2, so the function is ...

y = -1.2x² +6.6x +2
