which equation has roots of 3+i and 3-i
is x^2-6x+10=0
but can you show me the work
The quadratic equation with the roots 3+i and 3-i is:
x^2 - 6x + 10 = 0
How to find the equation with the given roots?We know that a quadratic equation with the roots a and b is written as:
(x - a)*(x - b) = 0
Here the roots are 3 + i, and 3 - i.
Replacing that we get:
(x - 3 - i)*(x - 3 + i) = 0
Expanding the product on the left we get:
x^2 + x*(-3) + x*i + (-3)*x + (-3)*(-3) + (-3)*i + (-i)*x + (-i)*(-3) - i^2 = 0
Remember that i^2 = -1, then:
x^2 -3x + x*i - 3x + 9 - 3i - x*i + 3i + 1 =0
x^2 - 6x + 10 = 0

A partial payment is made on the date indicated. Use the United States rule to determine the balance due on the note at the date of maturity. (The Effective Date is the date the note was written.) Assume the year is not a leap year.Principal Rate Effective Date Partial Payment Maturity Date Amount Date $2000 4% April 1 $1000 May 1 June 1 The balance due on the note at the date of maturity is $nothing.(Round to the nearest cent as needed.)
The balance due on the note at the date of maturity is $1010.13.
What is meant by partial payment?The offering of a payment by cheque for less than the whole amount sought by the creditor is known as partial payment. It is standard practice to grant debt forgiveness in exchange for the tender of a "payment-in-full" check.
Given permission to apply the US rule
In the United States, a year is deemed to have 360 days for the purposes of calculating interest.
Given that the principal is $ 2000,
Interest rate = 4% = 0.04
The effective date is April 1.
The whole amount is $1,000.
May 1 = partial payment
Duration = 30 days (May 1 - April 1)
Therefore, interest = PTR = 2000 * 0.04 * 30/360 = $6.67
So value = $ 2000 + $6.67 = $6.67
Partial payment received = $1,000
As a result, value = $ 1006.67 = $2006.67 - $ 1000
Time T= 31
Interest = PTR * 31/360 * 0.04 = 3.46
So the total value is $1006.67 + $3.47 = $1010.13.
The note's outstanding balance at maturity is $1010.13.

She is billing World Bank Ksh 10,000 per participant while the hotel charges her Ksh 2,500 per participant for meals in addition to Ksh 225,000 fixed charge for the hall. Required:

y = mx + b.
In which the coefficients are given as follows:
m is the slope, representing the rate of change.b is the y-intercept, representing the value of y when x = 0.Hence in the context of this problem, the meaning of each coefficient is given as follows:
Slope: profit per participant.Intercept: fixed costs.Hence the values of each coefficient are given as follows:
m = 7500, as she is billing 10000 per participant while the hotel charges 2500 per participant.b = -225000, which is the fixed charge.Hence the profit function is given as follows:
P(x) = 7500x - 225000.
She breaks even when P(x) = 0, hence:

The speed of the current of the river will be 4.47 km per hour.
What is speed?Speed is defined as the length traveled by a particle or entity in an hour. It is a scale parameter. It is the ratio of length to duration.
We know that the speed formula
Speed = Distance/Time
A riverboat goes at a normal of 14km each hour in still water. the riverboat voyages 110km east up the Ohio waterway and 110km west down a similar stream in a sum of 17.5 hours.
Let 'y' be the speed of the current of the river. Then the equation is given as,
T = T₁ + T₂
17.5 = [110 / (14 + y)] + [110 / (14 - y)]
17.5 / 110 = (14 - y + 14 + y) / (196 - y²)
196 - y² = 176

The average rate of change over the interval x = -2 and x = 1 is 4
How to determine the average rate of changeThe equation is given as
f(x) = x² + 5x - 12
The interval is given as:
x = -2 to x = 1
Start by calculating the functions f(-2) and f(1)
So, we have
f(-2) = (-2)² + 5(-2) - 12 = -18
f(1) = (1)² + 5(1) - 12 = -6
So, the average rate over these intervals is calculated as:
Average rate = [f(1) - f(-2)]/[1 - -2]
This gives
Average rate = [-6 - -18]/[1 - -2]
Evaluate
Average rate = 4

What are Numerals?
Numerals are symbols or numerals used to represent numbers. They are used in math and other fields to represent quantities and measurements. Numerals can be written in different forms, such as Arabic numerals (1, 2, 3, etc.) or Roman numerals (I, II, III, etc.). Numerals are also used to label items, such as dates (e.g. May 4th, 2020), addresses (e.g. 1234 Main Street), and telephone numbers (e.g. 555-123-4567). Numerals are an important part of our everyday lives, used to count, measure, and express amounts.
Numerals are just a combination of digits that we know
for example if 0,1,2,3,4,5,6.....9
are the fundamental digits then numbers from these like
12,34,668,389,23,39 etc are called numerals
We can also conclude that all numbers have originated from numerals itself and numerals are basic unit of formation of numbers

Uan earn $5 per item he ell. How many item hould he ell to make a profit of $60 or more?
By resolving an equation, we may determine that Uan needs to sell 12 or more goods in order to generate a profit of $60 or more.
What do we mean by equations?A formula that describes how two expressions on each side of a sign are connected.
It typically has an equal sign and one variable.
Similar to this: 2x - 4 = 2.
Graphing, substitution, or elimination are the three methods that can be used to solve systems of equations.
To answer a problem by graphing, just plot the given equations on a graph and identify the point(s) where they all intersect.
So, a number of items Uan should sell to earn a profit of $60 or above:
We know that Uan earns $5 for each item he sells.
So, let x be the number of items Uan should sell.
Then, the equation will be:
5x = 60
Now, solve as follows:
5x = 60
x = 60/5
x = 12
Profit of $60: 12 items to sell
Profit more than $60: More than 12 items to sell
So, by resolving an equation, we may determine that Uan needs to sell 12 or more goods in order to generate a profit of $60 or more.

how does weather existe? I need help
Answer: How Weather Exists
Step-by-step explanation:
~I think you mean, how weather exists.
You see, "Weather" exists because of the atmosphere. Evidently, weather is the movement of the atmospheric gases around the planet that creates weather. Places like the Moon or Mercury do not have weather - only temperature changes.
~Hope this helped :)
