Answer:
9 1/9 per cousin
Step-by-step explanation:
if the aunt has 58 items to be distributed to 6 cousins, we would set a fraction of 58/6. performing that is 9 with 4/6 left over.
since there is 6 cousins, there will be 2/3 divided by 6 = 2/18, or 1/9

Which is the definition of a ray?
a part of a line that has one endpoint and extends indefinitely in one direction
the set of all points in a plane that are a given distance away from a given point
lines that lie in the same plane and do not intersect
a part of a line that has two endpoints
The definition of a ray is a part of a line that has one endpoint and extends indefinitely in one direction
A ray is part of a line that has one endpoint and extends indefinitely in one direction and has the folowing properties.
It has one starting point called its endpoint. It does not have height or width but has length. But, its length is not measurable since it extends forever.So, the definition of a ray is a part of a line that has one endpoint and extends indefinitely in one direction.

College precalc! If you could help me with range, too, that's be great.
Answer:
All together:
D:(-∞,∞)
R:(-∞,2]
Individually:
D: (-∞,-2], (-2,∞)
R: (-∞,-2], y=2
Step-by-step explanation:
So the way I like to think about Domain and Range is that the Domain is the set of real numbers which can be put into a function and the Range is the set of real numbers which you can get out from a function.
Looking at your given function, it looks like the piece-wise parts are f(x)=x and f(x)=2. Neither one of the functions has domain restrictions (you can plug anything into the first and second without getting any mathematical errors [like a 0 in the denominator]). And since the graph shows arrows in each end, indicating infinite continuation of the curve, the Domain is (-∞,∞).
Now for the outputs of each function, we can see that you'll be getting any number out for the f(x)=x portion. But, the f(x)=2 portion will always give you 2 for any input. So the Range is (-∞,2).
Now I'm honestly not too sure what the HW is asking you to do with this info... for the first part, maybe they want the individual domain and range values for each piece of the piece-wise while the second part asks for the overall? You might know what it's asking better then me since it's your class.
I'll include the overall and individual answers above. Comment with any questions.

___ power of 10 gives the answer 1,000,000,000? * 10 9 11 6
Answer:
9
Step-by-step explanation:
We see that we have 9 zeros.
We use the base 10 system to help us solve.
When we multiply anything by 10, we simply move the decimal place to the right.
Since we have 9 zeros, we move the decimal place 9 places to the right. Therefore, to get 1,000,000,000, we multiply 1 by 10⁹

Step-by-step explanation:
A quantity P obeys the exponential growth law P(t)=e5t (t in years).
At what time t0 is P=15? Use yr for years. t0=?
At what time t1 is P=20? Use yr for years. t1= ?
What is the doubling time for P? Use yr for years. The doubling time is ?
Answer:
the time at which P =15 is [tex]{t_o = 0.54161 \ years}[/tex]
the time at which P =20 is [tex]{t_1 = 0.59914 \ years}[/tex]
the doubling time [tex]{t = 0.138629 \ years}[/tex]
Step-by-step explanation:
From the information we are being provided with:
The quantity P i.e [tex]P(t) = e ^{5t}[/tex]
In order to determine the time at which P = 15, we have the following:
[tex]t= t_o[/tex] when P = 15
∴ [tex]e^{5t_o} = 15[/tex]
[tex]5t_o= In (15)[/tex]
[tex]t_o = \dfrac{1}{5}In 15[/tex]
[tex]t_o = \dfrac{1}{5} \times 2.70805[/tex]
[tex]{t_o = 0.54161 \ years}[/tex]
Hence, the time at which P =15 is [tex]{t_o = 0.54161 \ years}[/tex]
In order to determine the time at which P = 20, we have the following:
[tex]t= t_1[/tex] when P = 20
∴ [tex]e^{5t_1} = 20[/tex]
[tex]5t_1= In (20)[/tex]
[tex]t_1= \dfrac{1}{5}In (20)[/tex]
[tex]t_1 = \dfrac{1}{5} \times 2.9957[/tex]
[tex]{t_1 = 0.59914 \ years}[/tex]
Hence, the time at which P =20 is [tex]{t_1 = 0.59914 \ years}[/tex]
The doubling time at t = 0, mean P = 2
∴ [tex]e^{5t} = 2[/tex]
[tex]5t= In (2)[/tex]
[tex]t= \dfrac{1}{5}In(2)[/tex]
[tex]t = \dfrac{1}{5} \times0.693147[/tex]
[tex]{t = 0.138629 \ years}[/tex]
Hence, the doubling time [tex]{t = 0.138629 \ years}[/tex]

To calculate simple interest, the amount of interest, I, can be found using this formula, where P is the principal, r is the interest rate, and t is time: I=Prt Which formula can be used to determine the interest rate when the other variables are known? a.) r=IPt b.)r=I/Pt c.)r=IP/t d.) r=Pt/I
Answer:
b
Step-by-step explanation:
I = Prt Solve the equation for r
I = Prt Divide both sides by Pt to get r on one side of the equation by itself
Pt Pt Cancel the P and t on right side as P/P and t/t = 1
This leaves: I = r or r = I
Pt Pt
The interest rate formula with other known variables is R=I/PT. Therefore, the correct answer is option B.
The given simple interest formula is I=PRT.
Where, P is the principal, r is the interest rate, and t is time.
Simple interest is a method to calculate the amount of interest charged on a sum at a given rate and for a given period of time.
To calculate the interest rate:
By rearranging the formula I=PRT, we get
R=I/PT
Therefore, the correct answer is option B.

3+x/8=4
Answer:
x = 8
Step-by-step explanation:
3+x/8=4
We move all terms to the left:
3+x/8-(4)=0
We add all the numbers together, and all the variables
x/8-1=0
We multiply all the terms by the denominator
x-1*8=0
We add all the numbers together, and all the variables
x-8=0
We move all terms containing x to the left, all other terms to the right

Lou drives at 65 mi/h. Write an expression for the number of miles that Lou drives t hours.
Answer:
The expression for the number of miles that Lou drives t hours is t*65
Step-by-step explanation:
Two quantities are directly proportional when, when one of them is multiplied or divided by a number, the other is multiplied or divided respectively by the same number. That is, the relationship between the magnitudes is direct when one magnitude increases and so does the other (or when one magnitude decreases, so does the other).
The direct rule of three is used when the problem deals with two directly proportional quantities and is used to solve proportionality problems between three known values and one unknown, establishing a proportional relationship between all of them as follows:
a ⇒ b
c ⇒ x
So [tex]x=\frac{c*b}{a}[/tex]
In this case the rule of three can be applied in the following way: if in 1 hour Lou travels 65 miles, in t hours how much distance does he travel?
[tex]distance=\frac{t*65 mi}{1 h}[/tex]
distance=t* 65
The expression for the number of miles that Lou drives t hours is t*65
