The proportional relationship between the number of books on shelf and how much shelf space the books takes up is 1 inch
What is proportionality?
The concept of proportionality in mathematics denotes the linear relationship between two quantities or variables. The size of one item increases by twofold, whereas the size of the other quantity decreases by one-tenth of the earlier amount.
When two or more parameters are directly or indirectly proportional to one another, the relationship is written as a = kb or a = k/b, where k denotes the direction of the relationship between the two variables. The proportionality constant, k.
As we know [tex]\frac{y}{x}[/tex] = constant of proportionality
So, [tex]\frac{y}{x}[/tex] will be
[tex]\frac{2}{2} = \frac{11}{11} = \frac{13}{13} = \frac{16}{16}[/tex] = 1
∴ it is 1 inch per book

One way to find this out is by just plain dividing the numbers, 7 ÷ 11 is 0.636363..., 7 ÷ 9 is 0.7777777..., and 7 ÷ 8 is 0.875. 7/11 is the smallest of all of them, then 7/9, and then 7/8.
Allie is playing basketball. She takes a shot 17 ft away from the basket. When the ball is 2 ft away from her, it is at a height of 10 ft above the floor. The ball reaches its highest height of 17 ft above the
floor when it is 9 feet away from her.
a. Find the value of a.
b. If the hoop is 10 ft high, how close would Allie have to be in order to make the basket?
a. The value of a is
(Simplify your answer.)
According to the vertex form of the parabola,
a) The value of a is -1/7.
b) And If the hoop is 10 ft high, the distance close to Allie have to be in order to make the basket should be 16 feet.
Vertex form of the parabola
The vertex form of the parabola can be given as,
y = a(x - h)² + k
Where
h,k are the coordinates of the vertex.
Given,
Allie is playing basketball. She takes a shot 17 ft away from the basket. When the ball is 2 ft away from her, it is at a height of 10 ft above the floor. The ball reaches its highest height of 17 ft above the floor when it is 9 feet away from her.
Here we need to find the following:
a. The value of a
b. If the hoop is 10 ft high, how close would Allie have to be in order to make the basket?
We know that, Allie takes a shot of 17 ft away and at the distance of 2 feet the ball achieve the height of 10 feet from the ground.
And the greatest height achieved by the ball is 17 ft above the floor.
Then the value of a is calculated by using the point that is obtained thorough the given details is,
=> (2, 10)
And the vertex of the equation are (9, 17)
When we apply these on the vertex form, then we get,
10 = a(2 - 9)² + 17
-7 = a(-7)²
49a = -7
a = -1/7
Therefore, the value of a is 1/7.
Now we have to find if the hoop is 10 ft high, The distance close to Allie have to be in order to make the basket-
Here the value of y is 10 and x is not known.
Now, we have to put these values on the equation then we get,
=> 10 = -1/7 (x - 9)² + 17
=> -7 = -1/7 (x -9)²
=> 49 = (x - 9)²
=>√49 = x - 9
=> x = 16
Therefore, if the hoop is 10 ft high, the distance close to Allie have to be in order to make the basket should be 16 feet.

The graph below illustrates the decay of a radioactive substance over t days.
Use the graph to estimate the average decay rate from t = 5 to t = 15 Note: Your answer will be negative.
The estimate of the average decay rate of change is -0.6
How to estimate the average decay rate of the function?From the question, we have the graph and the interval is given as
t = 5 to 15
This can also be represented and expressed as
(a, b) = [5, 15]
From the attached graph, we have
f(5) = 12
f(15) = 6
The estimate of the average decay rate of change is calculated as
Rate = [f(b) - f(a)]/[b - a]
This gives
Rate = [f(15) - f(5)]/[15 - 5]
So, we have
Rate = [6 - 12]/[15 - 5]
Evaluate
Rate = -0.6
Hence, the average decay rate of change is -0.6

A function is shown. F(x) = -7/8x + 11
What's the x-intercept?
What's the y-intercept?
Answer:
x-intercept (88/7,0), y-intercept (0,11)
Answers:
x intercept = 88/7
y intercept = 11
===============================================
Explanation:
To find the y intercept, we replace f(x) with 0 and solve for x.
f(x) = (-7/8)x + 11
0 = (-7/8)x + 11
(7/8)x = 11
7x = 8*11
7x = 88
x = 88/7 is the x intercept
It is located at (x,y) = (88/7, 0)
The x intercept always occurs when y = 0.
88/7 = 12.5714 approximately, but I would stick to the fraction form since it's most exact.
-------------------------------
The y intercept always occurs when x = 0.
f(x) = (-7/8)x + 11
f(0) = (-7/8)*0 + 11
f(0) = 0 + 11
f(0) = 11 is the y intercept
It is located at (0,11)
The y intercept is much easier to find since we just need to read off the last value of the function (aka the constant value).

A number line which shows -4, -1, 1, and 2 correctly plotted on a graph is shown in the image attached below.
What is a number line?In Mathematics, a number line can be defined as a type of graph with a graduated straight line which comprises both positive and negative numbers that are placed at equal intervals along its length.
This ultimately implies that, a number line primarily increases in numerical value towards the right from zero (0) and decreases in numerical value towards the left from zero (0). Therefore, the numerical values -4 and -1 would be plotted on the left hand side of zero (0) while the numerical values 1 and 2 would be plotted on the right hand side of zero (0) using a number line.
In this scenario, a number line would be used for the comparison of two or more numbers such as -4, -1, 1, and 2, and this is plotted in the graph shown in the image attached below.

RS" has coordinates R" (-1,4) and S" (-3,-2). What are the coordinates of the segment RS?
The original coordinates are R= (-6,-6) and S = (-4,0)
What is translation?
Translation in mathematics is a property in which we shift each coordinate on a line by a constant value.
We are given that we originally had a segment RS which is reflected over the line y = x and then translated by (x+3, y+4) after this the segment we get the coordinates are R'' (-1,4) and S( -3,-2)
We are asked to find the coordinates of R and S
To find the coordinates we first reverse the process we subtract 3 from both x coordinate and 4 from both y coordinate
Hence we get,
R' = (-1,4)-(3,4)
R' = (-4,0)
And
S' = (-3,-2)-(3,4)
S' = (-6,-6)
Now to find the original coordinates we reverse the coordinates
Hence we get,
R= (-6,-6) and S = (-4,0)
Therefore the coordinates are R= (-6,-6) and S = (-4,0)

given a salary raise of $4500. How much would Kayden make as a salary after 4 years
working for the company? What would be his salary after t years?
Salary after 4 years:
Salary after t years:
The salary of Kayden after 4 years will be $ 221,952.00
The annual salary is $48000
Salary rise is $4500
The rate of the this salary can be found out by [tex]\frac{48,000- 4500}{48000}[/tex]
= [tex]\frac{43,500}{48,000}[/tex] × 100

A local candy shop sells boxes of chocolate for $3.75 each. If a customer purchases six or more boxes, the cost is only $3.25 per box, plus the customer has an additional $5 fee per order. C(x) represents the total cost and x represents the number of boxes, which can be modeled by the function below.
A piecewise function c of x in two pieces. The function is defined by part 1, which is 3 point 75 times x for x greater than 6, and part 2, which is 3 point 25 times x plus 5 for x is greater than or equal to 6.
Predict the cost of an order with 6 boxes.

$22.50
$24.50
$27.50
Answer:
$24.50
Step-by-step explanation:
In order to predict the cost of an order with 6 boxes, x has to be equal to 6.
So we have to use the function 3.25x + 5 for [tex]x\geq 6[/tex].
Then, plug in 6 for x and solve.

Ashlee is riding her bike to the beach. The beach is 17 miles from her home. She has already travelled 3/5 of the total distance. We need to find out how much farther she has to cycle.
Let the distance left to be covered by Ashlee be represented by the variable "D". The distance already covered by Ashlee on her cycle is calculated below.
d = (3/5)×17
d = 10.2
So she has already covered a distance of 10.2 miles. The distance yet to be covered is the difference between the total distance and the distance covered.
D = 17 - 10.2
D = 6.8
Hence, the distance yet to be covered by Ashlee is 6.8 miles.

What is an algebraic factor?An algebraic factor is the multiplication of two algebraic terms.
That term could be in the form of summation multiplication or in subtraction.
The root of the quadratic equation formed by the algebraic factor is always real.
As per the given polynomial,
p(x) = 4x³ + cx² + x + 2
Divide 4x³ + cx² + x + 2 by (x+2)
First quotient = 4x²
Then, (4x³ + cx² )- (4x³ + 8x²)
Now in order to become it zero c must be the same as 8.
c = 8
Then, the second quotient = 1
(x + 2) - (x + 2) = 0
So, 4x³ + cx² + x + 2 = (x + 2)(4x² + 1)
