Let y represent the total cost of publishing a book (in dollars). Let x represent the number of copies of the book printed. Suppose that x and y are related by the equation y = 1100 + 15x.Answer the questions below.What is the change in the total cost for each book printed?What is the cost to get started (before any books are printed)?
y = 1100 + 15x.
Rewriting
y = 15x+1100
This is in slope intercept form
15 is the slope. It is the change for each x
It is the change for each book
The change in total cost for each book is 15 dollars
The y intercept is 1100. It is the cost when x =0. It is the cost when there are no books printed.
It is the cost to get started
The start up cost is 1100 dollars.
Add 7 3/10 simlify the answer and write it as a mixed number ?17/3011 7/2511 7/3011 17/30
To add mixed numbers first, we can add the whole numbers:
[tex]7+4=11[/tex]Now, we can add the fractions. For this, we can find the lowest common denominator (LCD) of both denominators. The LCD is the lowest number that is evenly divisible by both numbers. Since the denominators of the fractions are 10 and 15, the LCD is 30 because 30 is the smallest number that is divisible by 10 and 15. Then, we have:
[tex]\begin{gathered} \frac{3}{10}+\frac{4}{15}=\frac{3\cdot3}{10\cdot3}+\frac{4\cdot2}{15\cdot2} \\ \frac{3}{10}+\frac{4}{15}=\frac{9}{30}+\frac{8}{30} \\ \frac{3}{10}+\frac{4}{15}=\frac{9+8}{30} \\ \frac{3}{10}+\frac{4}{15}=\frac{17}{30} \end{gathered}[/tex]Therefore, the result of adding the given mixed numbers is:

what is the solution to the equation below? (round your answer to two decimal places.) 6•inx=9.1
ANSWER
B. x = 4.56
EXPLANATION
To solve this equation, first, we have to divide both sides by 6,
[tex]\begin{gathered} \frac{6\cdot\ln x}{6}=\frac{9.1}{6} \\ \\ \ln x=\frac{9.1}{6} \end{gathered}[/tex]Then apply the base exponent rule of logarithms,
[tex]a^{\log_ab}=b[/tex]So, in this case, we have to raise e to each side of the equation,
[tex]\begin{gathered} e^{\ln x}=e^{9.1/6} \\ \\ x\approx4.56 \end{gathered}[/tex]Hence, the solution is x = 4.56, rounded to two decimal places.

Find h (-4), h (0), and h (1).
Answer:
The piecewise function is given below as
[tex]h(x)=\begin{cases}\frac{1}{2}x-2,x<-2 \\ (x-1)^2-1.-2\leq x\leq1 \\ 2,x>1\end{cases}[/tex]Step 1:
To figure out h(-4),
The function that satisfies this is given below as
[tex]\begin{gathered} \frac{1}{2}x-2,x<-2 \\ \text{note:} \\ -4<-2 \end{gathered}[/tex]Therefore,
Substitute the value of x=-4
[tex]\begin{gathered} \frac{1}{2}x-2 \\ h(-4)=\frac{1}{2}(-4)-2 \\ h(-4)=-2-2 \\ h(-4)=-4 \end{gathered}[/tex]Hence,
h( -4 ) = -4
Step 2:
To figure out h(0)
The function that satisfies this condition is given below as
[tex]\begin{gathered} (x-1)^2-1.-2\leq x\leq1 \\ \text{note:} \\ 0<1 \end{gathered}[/tex]Hence,
Substitue the value of x = 0
[tex]\begin{gathered} (x-1)^2-1.-2\leq x\leq1 \\ h(0)=(0-1)^2-1 \\ h(0)=(-1)^2-1 \\ h(0)=1-1 \\ h(0)=0 \end{gathered}[/tex]Hence,
The value for h( 0 ) = 0
Step 3:
To figure out h( 1)
The function that satisfies this condition is given below as
[tex](x-1)^2-1.-2\leq x\leq1[/tex]Substitute x= 1 in the equation below
[tex]\begin{gathered} (x-1)^2-1.-2\leq x\leq1 \\ h(1)=(1-1)^2-1 \\ h(1)=0-1 \\ h(1)=-1 \end{gathered}[/tex]Hence,
The value of h(1) = -1
Jan made a mixed vegetable soup using tomatoes and carrots. Forty percent of the
tomatoes. If she used a total of 50 tomatoes, how many carrots should she use?
Jan should use 75 carrots for mixed vegetable soup.
Let us assume the total number of tomatoes and carrots be x. So, as per the mentioned information, the equation will be -
40%×x = 50
Converting percentage to fraction
40/100×x = 50
x = 50×100/40
Cancelling zero and performing division
x = 5×25
Performing multiplication
x = 125
Total number of vegetables = number of tomatoes + number of carrots
125 = 50 + Number of carrots
Number of carrots = 125 - 50
Performing subtraction
Number of carrots = 75
Therefore, Jan should use 75 carrots.

Factor completely the trinomial 10x^2 + 19x + 7
From the problem :
[tex]10x^2+19x+7[/tex]Factor completely :
We need to find the factors of 10 and 7
We have :
10 = 1 x 10
10 = 2 x 5
7 = 1 x 7
We will do trial and error, The sum of the product of the factors must be equal to the middle term which is 19
Let's say for 10 = 1 x 10 and 7 = 1 x 7
(1 x 7) + (1 x 10) = 17 not equal to 19
(7 x 10) + (1 x 1) = 71 not equal to 19
try the other factors of 10.
10 = 2 x 5 and 7 = 1 x 7
(2 x 7) + (5 x 1) = 19 Equal to 19
Now we have the factors, let's arrange in this way :
[tex](O+I)(I+O)[/tex]O will be the outer and I will be the inner.
O is the paired factors of 10 and 7
For O, we have 2 and 7
For I, we have 5 and 1
This will be :
[tex](2x+5)(x+7)[/tex]The answer is (2x + 5)(x + 7)

cual es el valor absoluto de -x+2
The absolute value of -x+2 is 2-|x-2|.
What is the Absolute Value ?
The non-negative value of a real number x without regard to its sign is known as its absolute value or modulus in mathematics and is indicated by the symbol |x|.
Since the absolute value is isolated, we set it equal to the positive and negative of the constant
Therefore,
|(-x+2)| =
for x < 2, -(-x + 2)
for x ≥ 2, (x + 2)
Hence, This is so that no matter the value of x, the value of the function is always greater or equal to 0.

Some arithmetic sequences could be easier to write as functions. As long as I know what value "n" has, I can find out any term in a particular Sequence whenever I need to. You might choose the implicit term over the prior term of a Sequence if it is known.
What is meant by Arithmetic Sequences?The arithmetic mean can be calculated as one approach. Divide the total by the total number of values after adding up all the values.
A series of numbers called an arithmetic progression or arithmetic sequence has a constant difference between the terms. An arithmetic progression with a common difference of 2 is found, for instance, in the numbers 5, 7, 9, 11, 13, and 15.

A packet of carrot seeds has a germination rate of 92%. In other words, the probability of any
seed sprouting is 0.92. How many seedlings would you expect in a row of 50 seeds?
The number of constructive seedlings in a row of 50 seeds is 46.
What is probability of a given event and how can it be analyzed?
Potential is described by probability. This branch of mathematics deals with the occurrence of a random event. The value's range is 0 to 1. Probability generally refers to the degree to which something is likely to occur. Utilize probability to ascertain how likely something is to occur. Many things are hard to predict with 100% certainty. We can only anticipate the possibility of an event occurring using it, or how likely it is. In the probability scale, 0 indicates an impossibility and 1 indicates a certainty. Every event's probability in a sample space is one.
Given, the germination rate of the seeds to seedlings is = 92%
Therefore, the probability of any seed sprouting is 0.92.
Hence the required number of seedlings can be expected in a row of 50 seeds = 50*0.92 = 46 seeds
Thus, the number of constructive seedlings in a row of 50 seeds is 46.

What is a number line?The visual representation of numbers on a straight line, either horizontally or vertically, is known as a number line. When numbers are written down on a number line, it is straightforward for humans to compare them and perform basic arithmetic operations on them. One might assume that a number line starts at zero (0). There are only negative numbers to the left of zero and only positive numbers to the right of zero. In other words, as we move to the right on a number line, the value of the numbers increases. This shows that the numbers on the right are more numerous than those on the left.
