Which polynomial function has a leading coefficient of 1 and roots 2i and 3i with multiplicity 1? f(x) = (x – 2i)(x – 3i) f(x) = (x + 2i)(x + 3i) f(x) = (x – 2)(x – 3)(x – 2i)(x – 3i) f(x) = (x + 2i)(x + 3i)(x – 2i)(x – 3i)
Answer:
[tex]P(x)=(x-2i)(x-3i)[/tex]
Step-by-step explanation:
Build a Polynomial Knowing its Roots
If we know a polynomial has roots x1, x2, ..., xn, then it can be expressed as:
[tex]P(x)=a(x-x1)(x-x2)...(x-xn)[/tex]
Where a is the leading coefficient.
Note the roots appear with their signs changed in the polynomial.
If the polynomial has a leading coefficient of 1 and roots 2i and 3i with multiplicity 1, then:
[tex]P(x)=1(x-2i)(x-3i)[/tex]
[tex]\mathbf{P(x)=(x-2i)(x-3i)}[/tex]
Answer:
a

Write \sqrt{-40}
−40
in simplest radical form.
Answer:
2*{2*i*√(10) - 20}
Step-by-step explanation:
i will interpret your expression as being
sqrt{-40} − 40. The first term factors to
sqrt{-4*10)
and the second stays as is.
Then we have
sqrt(-4*10) - 40, or
i*2*sqrt(10) - 40, or
2*{2*i*sqrt(10) - 20}, or
2*{2*i*√(10) - 20}

Explain, step by step, how to arrive at a single rational number to represent the following expression. Show both a written explanation and the related math work for each step. 1 - 3/4 + (-12 1/4)
Answer:
-30
Step-by-step explanation:
first you should complete the equition of bracket
1-3/4+(-121/4)
= 1-3/4+(-30.25)
= 1-0.75+(-30.25)
=0.25+(-30.25)
=-30
hence the right answer is -30 :)

please help me with the math problem and show me how to do these kinds.
Thank you.
Answer:
The answer is 9
Step-by-step explanation:
for the equation:
move the -6x
x^2 + c - 6x
To find c :
c = (b/2)^2
this means you have to divide the coefficient of x by 2 then square the result

Ast year, Saleh opened an investment account with $8600. At the end of the year, the amount in the account had decreased by 23.5%. How much is this decrease in dollars? How much money was in his account at the end of last year?
Given:
Initial amount = $8600
The amount in the account had decreased by 23.5%.
To find:
Decrease in amount and amount at the end of last year.
Solution:
The amount in the account had decreased by 23.5%. So,
Decreased amount = 23.5% of 8600
[tex]=\dfrac{23.5}{100}\times 8600[/tex]
[tex]=23.5\times 86[/tex]
[tex]=2021[/tex]
Now, the amount at the end of the last year is
Amount = Initial value - Decreased value
[tex]Amount=8600-2021[/tex]
[tex]Amount=6579[/tex]
Therefore, the decreased value is $2021 and the amount at the end of last year is $6579.
the length of the garden should be 15 feet longer than its width and the area is less than 100 ft^2
Answer:
If the perimeter is 200feet (two lengths and two widths) then one width+one length equals 100feet.
If the length is 10 feet longer than the width, then length = 55 feet, and width =45 feet
Therefore the area of the rectangle is 45x55 feet, which equals 2475 sq.ft
Step-by-step explanation:
Hi! Nice to meet you and have a great day
Answer:
If the perimeter is 200feet (two lengths and two widths) then one width+one length equals 100feet.
If the length is 10 feet longer than the width, then length = 55 feet, and width =45 feet
Therefore the area of the rectangle is 45x55 feet, which equals 2475 sq.ft
