Janice trains for a marathon by running the distances shown in the graph.
Which equation models the relationship between the number of weeks Janice trains, x, and the total number of miles she runs, y?
Responses
y=1.5x+2.25
y = 1 . 5 x + 2 . 25
y=2.25x+1.5
y = 2 . 25 x + 1 . 5
y=3x+1.5
y = 3 x + 1 . 5
y=1.5x+3
y = 1 . 5 x + 3

To see if a table of values represents a linear function, check to see if there's a constant rate of change. If there is, that's ur answer.
1. Is the average change in population the same now as it was 50 years ago? Explain your answer.
2. Reflect on the interpretation of your data.
3. What should you consider when comparing population growth (or decline) over different intervals of time? Hint: What factors influence population growth or decline? Explain fully and provide examples where needed.
1. The average change in population is not the same now as it was 50 years ago. The population growth rate can vary greatly from year to year and decade to decade, and is influenced by a variety of factors such as birth and death rates, immigration, and emigration. Therefore, it is important to analyze the specific data for each time period to determine the average change in population.
2. When interpreting data on population growth or decline, it is important to consider the factors that influence population change and to analyze the data in the context of the specific time period being studied. It is also important to consider the accuracy and reliability of the data source, as well as any potential biases or limitations in the data.
3. When comparing population growth or decline over different intervals of time, it is important to consider a range of factors that can influence population change, such as birth and death rates, migration patterns, economic and environmental conditions, and government policies. For example, population growth rates in a country may be influenced by changes in healthcare access or advancements in technology that reduce infant mortality rates or increase life expectancy. In addition, migration patterns can greatly impact population growth rates, as some regions may experience large influxes of immigrants or emigrants at different periods in time. When comparing population data over different intervals of time, it is important to take into account these and other factors that may contribute to population growth or decline.
hello :> Can someone help please? if you can a brief explanation would be nice. ty !
Answer:
x = 12. 4¯
(the 4 is supposed to be under the line)
The line sgnifies that the number goes on forever, such as
12.444444444444 and so forth
anyways, youre going to use "cross multiply and divide" which means you multipy the two number on one side top, and the other bottom. Make sure its the one that does have the x!
I multipled 7 * 8 which equals 56, and the leftover number, which is 4.5 is what i divide. When we divide that we get our answer, which is x.
Hope this helped!!
Step-by-step explanation:
Answer:
x= 12.444
Step-by-step explanation:
The fractions are equal.
7÷4.5= 1.555
8·1.555=12.444
x=12.444

A car rental service charges a flat rate of $175 plus $65 each additional day. Not including tax, what will the total price of the car rental be after 4 days of renting? Use d to represent the number of days the car is rented and use t to represent the total of the rental service.
t = 65d + 175
When d = 4,
t = 65(4) + 175 = $435
Answer:
$485

find the value of x in the equation without evaluating the power
Answer:
4
Step-by-step explanation:
Here's my method of doing this:
We'll be using logarithms
Our question is:
\((\frac{1}{3})^{2}\) × \((\frac{1}{3})^x\) = \(\frac{1}{729}\)
If we don't want to evaluate any powers at all we'll have to make each term have the same base (so that we can ignore the base — \(\frac{1}{3}\))
we need to figure out what power of a \(\frac{1}{3}\) the \(\frac{1}{729}\) is.
what we can do is the following:
\((\frac{1}{3})^?\) = \(\frac{1}{729}\)
\(3^?\) = 729
If we take the "log" of each, we can find out what power of 3 gives 729.\(log(3^?) = log\ 729\)
We must remember this rule: \(log(a^n) = n \times log(a)\)
\(? \times log 3 = log 729\)
\(? = \frac{log\ 729}{log\ 3}\)
? = 6 (with a calculator)
This means that to get 729, we need to do \(3^6\)
Therefore \((\frac{1}{3})^6 = \frac{1}{729}\)
We can now solve the equation!
\((\frac{1}{3})^{2}\) × \((\frac{1}{3})^x\) = \(\frac{1}{729}\)
\((\frac{1}{3})^{2}\) × \((\frac{1}{3})^x\) = \((\frac{1}{3})^6\)
Since each term of our equation has the same base of \(\frac{1}{3}\) we can ignore it and just deal with the powers!
We must remember this rule: \(x^a \times x^b = x^{a + b}\)
Using this rule:
\((\frac{1}{3})^{2}\) × \((\frac{1}{3})^x\) = \((\frac{1}{3})^6\) becomes...
\(2 + x = 6\)
\(x = 6 - 2 = 4\)

Suppose a certain breed of dog loses about 75 hairs per day. What integer represent this change in the amount of hair per week write a mathematical argument that can be used to defend your solution
Answer:
75 hairs/ day = 525 hairs / week
Step-by-step explanation:
so your base question for this is 75 hairs/ day =? h/ week. how? if the dog is losing 75 hairs per day, then you would do 75 x 7 becuase there are 7 days in a week. the answer to that would give you how many hairs the dog was losing per week. (see attached image for reference)

Luther evaluated 2³ as 9 and Wade evaluated 3² as 9. Are both students correct? Explain why or why not.
Answer:
No, Wade is correct Luther is incorrect
Step-by-step explanation:
3^2 =3*3 which is 9
2^3 = 2*2*2 which is 8
The two powers are not equal. Wade is correct, but Luther misinterpreted 2 to the power of 3 as 2 factors of 3. He switched the base and exponent. Luther’s value should be 2 times 2 times 2, which is 8.

How does graphing the solution help you to be sure you have correct solution?
Answer:
It helps you see the visual move of what you were doing. If you weren't moving anything it would help you see if it is true or false. Say you put a dot on the origin (0,0), then you have to go (x+7,y+3) then moving it on a graph would help show you. So overall it's a visual help to people.

Veronica spent a minimum of $65 on a doll and accessories for the doll. The doll cost $26 and the accessories cost $13 each. Write an inequality can be used to find the possible values for x, the number of doll accessories Veronica could have bought.
Answer: \(13x+26 \ge 65\)
If you solve for x, you get \(x \ge 3\) which means she bought at least 3 accessories.
=========================================================
Explanation:
x = number of accessories, some nonnegative whole number
13x = amount spent on accessories only
For instance, let's say she bought 5 accessories. This means she spent 13x = 13*5 = 60 dollars on those five items.
This is on top of the $26 Veronica paid for the doll itself (without the accessories). In total, she spent 13x+26 dollars for the doll (26) and the accessories (13x) combined.
We're told she spent a minimum of $65, which means that she spent 65 or more dollars.
So the total cost (13x+26) must be equal to 65 or larger than 65.
We write that as \(13x+26 \ge 65\) which sets up the inequality.
----------------------------
Let's solve for x
\(13x+26 \ge 65\\\\13x \ge 65-26\\\\13x \ge 39\\\\x \ge 39/13\\\\x \ge 3\\\\\)
So x can be equal to 3, or larger than it.
The lowest value x can be is 3.
Meaning that she bought at least 3 accessories (ie she bought 3 or more accessories).
Answer:
Step-by-step explanation:
65= 26+13x

Answer: 803.84
Step-by-step explanation: pi * r^2 * height
Answer:
803.84
Step-by-step explanation:
because its pi x r² x height
in this case the radius is 4 because the diameter is 8 and half would be 4 so its 4² which is 16 and the height is 16 and you mulitply pi which is 3.14 so 16 x 16 x 3.14= 803.84cm
