The relative order of the metric prefixes Milli- < Centi- < Micro- < Kilo-
The relative order of the metric prefixes of kilo-, micro-, centi-, and milli- is milli-, centi-, micro-, and kilo-. This order is determined by the exponential values of each prefix.
Milli- is equal to 10-3, centi- is equal to 10-2, micro- is equal to 10-6 and kilo- is equal to 103. The exponential values are used to determine the relative order of the prefixes. The lowest exponential value is milli-, making it the smallest metric prefix and the highest exponential value is kilo-, making it the largest metric prefix.
When the exponential values are compared, it is clear that the order of the prefixes is milli- < centi- < micro- < kilo-. This order is used to determine the relative size of the metric prefixes when measuring the same base unit.
For example, if the base unit is meter, then millimeter is the smallest measure and kilometer is the largest measure. The exponential values of the metric prefixes determine the relative order of the base unit.

Find all the complex roots. Leave your answer in polar form with the argument in degrees. The complex fifth roots of 3. Zo= ___ (cos ___º + i sin ___º)z₁=___(cos___º + i sin ___º)z2=___(cos___º + i sin___º) z3=___ (cos___º + i sin___º) z4=___(cos___º + i sin___º)
The complex fifth roots of 3 are Z₀ = ∛3 (cos 0° + i sin 0°), Z₁ = ∛3 (cos 72° + i sin 72°), Z₂ = ∛3 (cos 144° + i sin 144°), Z₃ = ∛3 (cos 216° + i sin 216°) and Z₄ = ∛3 (cos 288° + i sin 288°)
The complex fifth roots of 3 can be found by finding the roots of the equation z^5 = 3. To find the roots in polar form, we first convert 3 to polar form:
3 = |3| (cos 0 + i sin 0) = 3 (cos 0 + i sin 0)
Next, we find the argument of the fifth roots, which is equal to 360°/5 = 72°. The polar form of the first root is then:
z₁ = ∛3 (cos 0° + i sin 0°) = ∛3 (cos 0° + i sin 0°)
The polar form of the other roots can be found by rotating the argument by 72°, 144°, 216°, and 288° respectively. The result is:
z₂ = ∛3 (cos 72° + i sin 72°)
z₃ = ∛3 (cos 144° + i sin 144°)
z₄ = ∛3 (cos 216° + i sin 216°)
z₅ = ∛3 (cos 288° + i sin 288°)

2x + 4 / 2 - 3x / x - 2 = X
On solving the given equation, the value of x = -4.
Finding the value of f(x) =... or y =... that corresponds to a certain value of x is what it means to evaluate a function.
Simply swap out all instances of x with the value of x to do this. You must substitute a number for each variable and carry out the arithmetic operations in order to evaluate an algebraic expression.
Since 6 + 6 equals 12, the variable x in the example above is equal to 6. If we are aware of the values of our variables, we can substitute those values for the original variables before evaluating the expression.
Given,
[tex]\frac{2x + 4}{2} - \frac{3x}{x-2} = x\\ \\[/tex]
Taking LHS

Let f(x) = 2√x.
If g(x) is the graph of f(x) shifted down 1 units and right 6 units, write a formula for g(x).
The formula for g(x) is 2√(x-6) + 1. The solution has been obtained using the concept of translation.
What is translation?
In mathematics, a translation involves moving a shape up, down, left, or right. The translated shapes appear to be exactly the same size as the original ones; thus, the shapes are consistent with one another. Just one or more directions have been changed. There is no change to the shape because it is simply being moved from one location to another.
The object's shift in location can occur in a variety of ways, such as initially moving left, then turning right, and so on. Each point on the form will translate by the same number of units.
We are given f(x) = 2√x
Now, shifted down 1 unit, we get
2√x + 1
Also, shifted right 6 units, we get
2√(x-6)
So, g(x) = 2√(x-6) + 1
Hence, the formula for g(x) is 2√(x-6) + 1.

You deposit $120 in an investment account that earns 6.4% annual interest compounded quarterly write a function that represents the balance y (in dollars) of the investment account after t years
Answer:
$ balance = 120*(1+6.4%/4) ^4t
Step-by-step explanation:
principal =120
r =6.4% annual = 1.6% per quarter compounding every quarter
so 4 times a year, for t years
$ balance = 120*(1+6.4%/4) ^4t
The function that represents the balance of the investment account after t years is [tex]y = 120 (1.016)^{4t[/tex].
How to calculate the compound interest?The formula for calculating the balance of an investment account that earns compound interest is:
[tex]A = P (1 + \dfrac{r}{n})^{nt}[/tex]
where:
A = the balance after t years
P = the principal (initial amount deposited)
r = the annual interest rate (as a decimal)
n = the number of times the interest is compounded per year
t = the time in years
In this case, we have:
P = $120
r = 6.4% = 0.064 (as a decimal)
n = 4 (compounded quarterly)
Therefore, the function that represents the balance y (in dollars) of the investment account after t years is:
[tex]y = 120 *(1 + \dfrac{0.064}{4})^{4t}[/tex]
Simplifying the expression inside the parentheses, we get:

swimming Y)can be described using the
equation y = 266x, where Prepresents the number of hours Davis swims. How many more calories will Davis burn running for 30 minutes) than swimming for 30 minutes assuming the rates remain constant
Answer:
...
Step-by-step explanation:
To find the number of calories Davis burns while running for 30 minutes, we can use the information that he burns 1080 calories running for 2.5 hours.
We know that 30 minutes is 1/120 of 2.5 hours. So, we can divide the total number of calories by 120 and we get the calorie burn for 30 minutes:
1080 calories / 120 = 9 calories
The number of calories Davis burns while swimming for 30 minutes can be determined by using the equation y = 266x, where x represents the number of hours he swims. We know that he swims for 30 minutes, or 1/120 hours, so we can plug that value into the equation:
y = 266(1/120) = 2.216 calories
So, Davis burns 7 calories more running for 30 minutes than swimming for 30 minutes, assuming the rates remain constant.

What is a complex number?
Complex numbers are those that are expressed as a+ib, where a and b are actual numbers and i is a imaginary number called a "iota."
The given complex number equation is (3+8i)/(2+8i)=3/2
Simplify both sides of the equation.
On the left side, there is -
= (3+8i)/(2+8i)
= (3+8i)/(2+8i) × (2-8i)/(2-8i)
= (6+24i-24i-64i²)/(2² + 2×8i-8i²)
= (-64i² + 24i + 6)/(-64i² + 16)
= (24i + 6)/(-64i² + 16)
On the right side, there is -
3/2 = 3/2
It can be seen that the simplified forms of both sides are not equal, so the original statement is false.
To make the statement true, change the right side of the equation to the left side simplified form.

if a pizza feeds 3 kids, but you need to feed 6, what would the scale factor be for calculating how many pizzas you need?
Answer:
2
Step-by-step explanation:
If a pizza feeds 3 kids and you need to feed 6 kids, the scale factor for calculating how many pizzas you need would be 2.
A scale factor is used to determine the relationship between the size of an object and a similar or corresponding object. In this case, you have a pizza that can feed 3 kids and you need to feed 6 kids, so the relationship between the number of kids that can be fed by one pizza and the number of kids you need to feed is 6/3 = 2
So, you need to double the quantity of pizza to feed 6 kids, therefore the scale factor would be 2.

use left rectangles and delta (x) = 0.5 to approximate the area under f(x) = (2x)^2 +6 from x = 2 to x=4 . give one decimal place in your answer.
The estimated area under the curve is 112.
We can use the left rectangle method to approximate the area under the curve f(x) = (2x)^2 + 6 from x = 2 to x = 4.
First, we need to choose a value of Δx = 0.5, which will determine the width of the rectangles. Then, we can find the height of each rectangle by evaluating the function at the left endpoints of the intervals.
For x = 2, the height of the first rectangle is f(2) = (2 * 2)^2 + 6 = 20.
For x = 2.5, the height of the second rectangle is f(2.5) = (2 * 2.5)^2 + 6 = 28.25.
For x = 3, the height of the third rectangle is f(3) = (2 * 3)^2 + 6 = 42.
For x = 3.5, the height of the fourth rectangle is f(3.5) = (2 * 3.5)^2 + 6 = 57.75.
For x = 4, the height of the fifth rectangle is f(4) = (2 * 4)^2 + 6 = 76.
Finally, we can multiply the height of each rectangle by its width (0.5) to find the area of each rectangle:
Area of first rectangle = 20 * 0.5 = 10
Area of second rectangle = 28.25 * 0.5 = 14.125
Area of third rectangle = 42 * 0.5 = 21
Area of fourth rectangle = 57.75 * 0.5 = 28.875
Area of fifth rectangle = 76 * 0.5 = 38

lan collects stamps. He put 34% of his stamp collection in an album. If there are
204 stamps in the album, how many stamps does he have in his collection?
well, there are a total of "x" stamps in his collection, which oddly enough is 100%.
now, we know that 34% of "x" is 204, what the heck is "x"?
[tex]\begin{array}{ccll} amount&\%\\ \cline{1-2} x & 100\\ 204& 34 \end{array} \implies \cfrac{x}{204}~~=~~\cfrac{100}{34} \\\\\\ \cfrac{ x }{ 204 } ~~=~~ \cfrac{ 50 }{ 17 }\implies 17x=10200\implies x=\cfrac{10200}{17}\implies x=600[/tex]

59. You put $500 into a bank account that earns 2% interest. Determine each of the following.
a. The value of the account after 3 years if compounded annually.
b. The value of the account after 5 years if compounded quarterly.
c. The value of the account after 10 years if compounded monthly.
d. The value of the account after 20 years if compounded continously.
Answer:
[tex]a. \;\; \boxed{\$ 530.60}[/tex]
[tex]b.\; \;\boxed{ \$552.45}[/tex]
[tex]c,\;\;\boxed{\$610.60}[/tex]
[tex]d. \;\; \boxed{\$745.91}[/tex]
Step-by-step explanation:
All four cases deal with compound interest on the same amount of $500 and same interest rate of 2%.
The only difference is in the frequency of compounding and time
Compound Interest Formula
[tex]\boxed{A = P\left(1 + \dfrac{r}{n}\right)^{n\cdot t}\\\\}[/tex]
where
In this particular problem we have
P = $500
r = 2% = 0.02
These are common for all parts of the question
Only n an t are different for each of the question sub-parts
Part a
Compounding is done annually (once a year) for 3 years
n = 1
t = 3 years
n · t = 3
[tex]A = 500\left(1 + \dfrac{0.02}{1}\right)^3\\\\A = 500\left(1.02\right)^3\\\\A = 500(1.061208)\\\\A=\boxed{\$ 530.60}[/tex]
For accuracy of calculations, I will not compute and store the exponent part, I will perform the calculations in one shot
Part b
Here the compounding is done quarterly (4 times a year) for 5 years
n = 4
t = 5 years
nt = 4 · 5 = 20
[tex]A = 500\left(1 + \dfrac{0.02}{4}\right)^{20}\\\\\\A = 500(1.005)^{20}\\\\A =\boxed{ \$552.45}[/tex]
Part c
Compounding done monthly(12 times a year) for 10 years
n = 12
t = 10
nt = 120
[tex]A = 500\left(1 + \dfrac{0.02}{12}\right)^{120}\\\\\\A = \boxed{\$610.60}[/tex]
Part d
First let's figure out what continuous compounding means
[tex]\fbox{\begin{minipage}[t]{1\columnwidth \fboxsep - 2\fboxrule}%\textsf{What is continuous compounding?} \\\textsf{Continuous compounding is the mathematicallimit that compound interest can reach if it's calculated and reinvestedinto an account's balance over a theoretically infinite number ofperiods. While this is not possible in practice, the concept of continuouslycompounded interest is important in finance. (Investopedia)}\}%\end{minipage}}[/tex]
The formula for continuous compounding can be determine by using the standard formula for periodic compounding and taking limits as
[tex]n \rightarrow \infty[/tex]
Therefore, for compounding continuously , the formula can be derived from
[tex]\lim _{n\to \infty } P\left(1 + \dfrac{r}{n}\right)^{nt}\\\\[/tex]
One of the limit formulas states
[tex]\lim _{x\to \infty } \left(1 + \dfrac{a}{x}\right)^{x} = e^a\\\\[/tex]
Therefore
[tex]\lim _{n\to \infty } \left(1 + \dfrac{r}{n}\right)^{n} = e^r\\\\[/tex]
So for the continuous compounding case, the formula is
[tex]\boxed{A = P \cdot e^{rt}}[/tex]
Here we have
r = 0.02
t = 20 years
rt = 20(0.02) = 0.4
Plugging in P = 500, and rt = 0.4 we get
[tex]A = 500 \cdot e^{0.4}\\\\A = \boxed{\$745.91}[/tex]
Answer:
a) $530.60
b) $552.45
c) $610.60
d) $745.91
Step-by-step explanation:

Can a slope have two negative signs
If the slope of the line has two negative signs, then it is positive.
How to obtain the slope of a linear function?The slope of a linear function represents the rate of change of the linear function.
If we have two points on the linear function, then the slope is obtained by the division of the change in the output by the change in the input.
If both changes are negative, then we are dividing two negative numbers, meaning that the slope is positive, as the quotient of two negative numbers is positive.

Place the correct value to complete the sentence.
Two boys, Zach and Carlos, go for a walk. Zach begins walking 20 seconds earlier
than Carlos
Two boys, Zach and Carlos, go for a walk. Zach begins walking 20 seconds earlier than Carlos and they both walked the same distance.
How to calculate the distance?
To calculate the distance that the boys walked, you would need to know their speed and the duration of their walk.
Speed is typically measured in units such as miles per hour (mph) or kilometers per hour (kph). If you know the speed of the boys and the duration of their walk in hours, you can calculate the distance they walked using the formula: distance = speed x time.
The sentence is describing a scenario in which two boys, Zach and Carlos, go for a walk. It is stated that Zach begins walking 20 seconds earlier than Carlos. This means that Zach starts his walk 20 seconds before Carlos does. It is also stated that both boys had walked exactly the same distance. This means that despite Zach starting his walk 20 seconds earlier than Carlos, they both covered the same distance during their walk.

A farmer has enough food to feed 20 animals in his cattle for 6 days. How long
would the food last if there were 10 more animals in his cattle?
Answer:
Food supply would only last 4 days
Step-by-step explanation:
(20 cattle)(6 days) = 120 cattle·days (this is the current feed supply on hand)
20 cattle + 10 = 30 cattle total
(120 cattle·days) / (30 cattle) = 4 days
