Answer:
The function is y=f(x)=11.95+0.50x
step by step explanation:
You pay $24 for 2 CDs, $48 for 4 CDs, $120 for 10 CDs. That means that each CD costs $12.
We can write a function rule:
Cost =$12 × (number of CDs) or f(x)=12x
You can see that a negative number turns into the same number, only positive, while a non-negative number stays the same. This means that the function being used here is the absolute value function: f(x)=∣x∣.
Coming up with a function based on a set of values really is as tricky as it looks. There’s no rule that will tell you the function every time, so you just have to think of all the types of functions you know and guess which one might be a good fit, and then check if your guess is right. In this book, though, we’ll stick to writing functions for linear relationships, which are the simplest type of function.
1. Maya has an internet service that currently has a monthly access fee of $11.95 and a connection fee of $0.50 per hour. Represent her monthly cost as a function of connection time.Let x= the number of hours Maya spends on the internet in one month
Let y= Maya’s monthly cost
The cost has two parts: the one-time fee of $11.95 and the per-hour charge of $0.50. So the total cost is the flat fee + the charge per hour × the number of hours.
The function is y=f(x)=11.95+0.50x.
2. Alfredo wants a deck build around his pool. The dimensions of the pool are 12 feet×24 feet and the decking costs $3 per square foot. Write the cost of the deck as a function of the width of the deck.
The function is y=f(x)=11.95+0.50x

Measure ofKIJ=
116°

ANWSER
JK=104°
KIJ=52
Answer:
JK=104°
KIJ=52
Step-by-step explanation:
The measures of the arc JK and angle KIJ of the given inscribed triangle are; Arc JK = 104° and ∠KIJ = 52°
What is the measure of the angles?
We have been given the arc KI = 116°, so we can find the angle KJI by intercept property.
Angle KJI = arc KI/ 2
Thus;
Angle KJI = 116°/2
Angle KJI = 58°
Now by angle sum property of a triangle, we get:
∠ K + ∠ I + ∠ J = 180°
70° + ∠I + 58° = 180°
∠I = 52°
By using intercept formula, we get arc KJ;
∠JIK = arc JK/ 2
2(∠ JIK) = arc JK
2(52°) = arc JK
arc JK = 104°

• a dozen brownies for $9.00
A. Determine if there is a proportional relationship between cinnamon rolls and the cost of cinnamon rolls. If there is determine the unit rate.
Answer:
it is $2.50 multiplied by 4
Step-by-step explanation:
this is because for every 1 cinnamon roll it is $2.50 and if you multiply that by 4 you get $10, or how much it costs for 1 roll

Step-by-step explanation:
18 is a suitable denominator for both fractions:
5/6 = 15/18
7/9 = 14/18
Then the difference is ...
5/6 -7/9 = 15/18 -14/18 = (15 -14)/18 = 1/18
A lake in East Texas was stocked with 3,000 trout in the year 2000. The number of fish in the lake is modeled by f(x) = 3000 + 100x, where x represents the number of years after 2000. Which of the following is the most reasonable domain and range for the function?
The correct answer is C
Step-by-step explanation:
I found this because the pond already has 3000 fish so y can not be less than 3000. Thus eliminating choice A since it says y>-3000.
That reasoning also eliminates answer D because real numbers can also include negatives.
Finally, since y has to be greater than 3000, answer B is not possible as it says y>0 which means it could be less than 3000.
In conclusion, Answer C is correct

As of the moment I am writing this question, the population of the United States is 326,891,705 people. You are building an app that targets the US population and expect to get 1/10 of 1% of the population using your app in the first 4 months. The estimated data you need to store per user averages 10 GB. What is the minimum storage you must plan to have in place for app to serve the users in the first 4 months
Answer:
3.3 PB
Step-by-step explanation:
It is given tat the population of the U.S = 326,891,705 people.
Population expected to use the app in first 4 months = 1/10 of 1%
Storage capacity of an user is = 10 GB
Therefore,
[tex]$\frac{1}{10} \text{ of}\ 1$[/tex] % = 0.1%
= 0.001
The user content = 0.001 x 326,891,705
= 326891.705 users
10 GB storage per user.
Therefore,
Size = 326891.705 x 10
= 3268917.05 GB
= 3.26 PB
Hence size of the minimum storage would be 3.3 PB.

Note that the cost for the rent is a function of the amount of the miles you drove. Let's call that [tex]C(m)[/tex].
Also note that the amount you pay will linearly increase, in other words, the increase in cost will always be the same for each mile. This tells us that our function is indeed a line, a first order polynomial of the form [tex]C(m) = am+b[/tex]
What would happen if you were to rent a truck and not drive it at all? You would pay only the one-time fee.
Therefore, [tex]C(0)=55[/tex]
So, [tex]C(m) = am + 50[/tex]
The cost will increase by $0.20 for each mile, wich tells us that [tex]a=0.20[/tex]
Finally, our expression is [tex]\boxed{C(m) = 0.2m+55}[/tex]
If we want to know how much would you pay if you drove 65 miles, we want to know what [tex]C(65)[/tex] is.
By plugging [tex]m=65[/tex] in the expression, we get
[tex]C(65) =68[/tex]
So you would pay $68

Each tire on a toy car has a diameter of 5.6 cm. the tires spun completely around 15 times when the car was pushed in a straight line.about how far was the car pushed
Answer:
I believe the answer is 84 centimeters.
Step-by-step explanation:
If the wheel is 5.6 centimeters in diameter, the car is traveling 5.6 centimeters per spin of the wheels. Therefore, you do the equation, 5.6 * 15 and get 84.
Alison Bender works for an accounting firm. To make sure her work does not contain errors, her manager randomly checks on her work. Alison recently filled out 12 income tax returns for the company's clients. Unknown to anyone, two of these 12 returns have minor errors. Alison's manager randomly selects three returns from these 12 returns. Find the probability that (a) Fewer than 2 of them contains errors
Answer:
Alison Bender and Income Tax Returns
The probability that fewer than 2 of the returns contains errors is:
8.333%
Step-by-step explanation:
a) Data and Calculations:
Number of income tax returns filed by Alison = 12
Number of returns with minor errors = 2
Percentage of returns with minor errors = 2/12 = 16.67%
Random sampling of returns by Alison's manager = 3/12 = 25%
Fewer than 2 = 1
The probability of 1 error in 12 returns = 1/12 = 0.08333
= 8.333%
b) Since Alison's manager randomly selects three returns from the 12 to check for errors, the probability of discovering the errors is 25% (3/12). However, the probability that less than 2 contains errors = 8.333% (1/12).
9965 divided by 19.9 estimate
Answer: 500.7
500.75 = 500.7
Step-by-step explanation:
The estimated value is 500
What is estimation?Estimating in math is a way of approximately calculating an answer (getting a 'rough answer') or to check its accuracy (the 'right answer').
Given that, 9965 divided by 19.9 estimate
Let 9965 ≈ 9970
19.9 ≈ 20
9970 ÷ 20
9970 / 20
= 498.5
≈ 500
Hence, the estimated value is 500.

What number can be put where the question mark is?
Justify your answer.
? =
Answer:
We need to put x = -4 where the question mark lies.
Step-by-step explanation:
Given the expression
[tex]\left(x^6\right)^0=x^4\cdot \:\:x^?[/tex]
First, solve the left-hand side of the equation
[tex]\left(x^6\right)^0[/tex]
[tex]\mathrm{Apply\:exponent\:rule}:\quad \:a^0=1,\:\quad \:a\ne \:0[/tex]
Thus, the expression becomes
[tex]\left(x^6\right)^0=1[/tex]
So we have to put the number which can make the right-hand side of the equation equal to 1.
Let's put x = 4 where the question mark lies and solve the equation to check whether the right-hand side of the equation becomes 1.
[tex]x^4\cdot \:\:x^{-4}[/tex]
[tex]\mathrm{Apply\:exponent\:rule}:\quad \:a^b\cdot \:a^c=a^{b+c}[/tex]
[tex]=x^{4-4}[/tex]
[tex]=x^0[/tex]
[tex]\mathrm{Apply\:exponent\:rule}:\quad \:a^0=1,\:\quad \:a\ne \:0[/tex]
[tex]=1[/tex]
Thus, both equations become equal when we put x = -4 on the question mark.
[tex]\left(x^6\right)^0=x^4\cdot \:\:x^{-4}[/tex]
[tex]1=1[/tex]
Therefore, we need to put x = -4 where the question mark lies.
