Using points of intersection, The resulting sketch should look like a parabolic arch opening upwards with its vertex at (-3, 9) and endpoints at (5, 45) and (-3, 9), with the region below the x axis for x < -3 and above the x axis for x > 5.
What are the intersection points?The locations on the coordinate plane where two curves meet or intersect are known as the points of intersection.
By locating the places where the two curves overlap and then sketching the area in between, the area bounded by the curves y = |9x| and y = x2 - 10 may be determined.
First, let's find the points of intersection:
y = |9x| = x² - 10
If 9x >= 0, then |9x| = 9x, and we have:
9x = x² - 10
x² - 9x - 10 = 0
This is a quadratic equation and can be solved using the quadratic formula:
x = (9 ± √(81 + 40)) / 2 = (9 ± √(121)) / 2 = (9 ± 11) / 2 = 5 or -3
If 9x < 0, then |9x| = -9x, and we have:
-9x = x² - 10
x² + 9x - 10 = 0
This is a quadratic equation as well and can be solved using the quadratic formula:
x = (-9 ± √(81 - 40)) / 2 = (-9 ± √(41)) / 2 = (-9 ± 6.4) / 2 = -3 or -1.2
So the two curves intersect at the points (5, 45) and (-3, 9).
Next, we can sketch the region enclosed by the curves:
For x < -3, y = |9x| is below y = x² - 10, so the region is below the x axis.
For -3 <= x <= 5, y = x² - 10 is above y = |9x|, so the region is above the x axis.
For x > 5, y = |9x| is above y = x² - 10, so the region is above the x axis.
The resulting sketch should look like a parabolic arch opening upwards with its vertex at (-3, 9) and endpoints at (5, 45) and (-3, 9), with the region below the x axis for x < -3 and above the x axis for x > 5.

Suppose another store sells a similar package, modeled by a linear function rule with initial value at 5.75. Explain which store had the better deal
Answer:
The linear function for the first store is y = 2.5x + 10.75, where x is the number of comic books and y is the cost of the package. The linear function for the second store is y = 2.5x + 5.75. The second store has the better deal, as the cost of the package is lower for any given number of comic books.
A B and C are points on the circumference of a circle. XY is a tangent to the circle at the point A.
Angle BAY=72 and angle ABC=54.
Prove that triangle ABC is an isosceles triangle.
You must give a reason for any statement or any calculation you carry out.
( do not answer if you don't know the answer, thank you. )
By using the tangent property of a circle, it has been proved that ABC is isosceles
<BAY = 72°
< ABC = 54°
What is a circle's tangent?
First, it's crucial to understand circles.
Every point on a circle keeps a set distance from the center point in a two-dimensional, rounded form known as a circle. The circle's radius is the fixed separation.
The tangent to a circle is the straight line that intersects the circle at any point.
Then Now
<ACB = <BAY = 72° ( angles in alternate segments)
<ABC + <ACB + < CAB = 180° { being sum of angles of triangle }
54° + 72° + <CAB = 180°
<CAB = 180° - 126°
<CAB = 54°
Hence
ABC is an isosceles triangle
(being <CAB = <ABC)

question content area top part 1 what is the difference between an observational study and an experiment?
The difference is that in an observational study, the researchers do not control treatment, and in an experiment, they do.
An experiment is what?An experiment is a method used to verify or disprove a theory, as well as to determine something's effectiveness or likelihood.
An experiment vs an observational research differs fundamentally in that:
Members of a sample are measured or surveyed during an observational study without any attempt to manipulate them.
In an experiment, decisions are made under controlled conditions, subjects are divided into groups, and one group is given therapy while the other is left untreated. The main distinction between well-executed observational studies and experimental designs is that the replies of participants are unaffected, whereas in experiments, at least some participants are subjected to a treatment condition at random.
As a result, the researchers in an experiment control the therapy, but they do not in an observational study.

determine the probability p that all the students with a's and b's are female and all the students with c's and d's are male
The probability P that all the students with A’s and B’s are female and all the students with C’s and D’s are male is 0.0000907 or 0.00907%.
To determine the probability P, we can use the formula for combinations:
P = (number of ways to select A's and B's from the females) * (number of ways to select C's and D's from the males) / (number of ways to assign grades to all students)
Let's first find the number of ways to select A's and B's from the females:
There are 2 ways to select 2 A's from 7 females.
There are 7 choose 5 ways to select 5 B's from 7 females, which is 21.
So, there are 2 * 21 = 42 ways to select A's and B's from the females.
Next, let's find the number of ways to select C's and D's from the males:
There are 8 ways to select 8 C's from 11 males.
There are 11 choose 3 ways to select 3 D's from 11 males, which is 165.
So, there are 8 * 165 = 1320 ways to select C's and D's from the males.
Finally, let's find the number of ways to assign grades to all students:
There are 18 choose 2 ways to select 2 A's from 18 students, which is 153.
There are 18 choose 5 ways to select 5 B's from 18 students, which is 18564.
So, there are 153 * 18564 = 2827672 ways to assign grades to all students.
Putting it all together, the probability P is:
P = (42) * (1320) / (2827672) = 0.0000907
Therefore, the probability P that all the students with A’s and B’s are female and all the students with C’s and D’s are male is 0.0000907 or 0.00907%.

3 (q − 7) = 27
EXPLAIN PLEASE AND TYSM
Answer: q = 16
Step-by-step explanation:
When given the equation 3(q - 7) = 27, you would solve for the variable.
The variable in this equation is q, so we need to isolate the variable.
Solving process:
3(q - 7) = 27
lets distribute, due to the orders of PEMDAS.
PEMDAS stands for: Parenthesis, Exponents, Multiplication, Division, Addition, and Subtraction.
3(q - 7) = 27
distributing is multiplying the number correlated outside of the parenthesis with the inside components.
3q - 21 = 27
lets add 21 to both sides
3q = 48
now lets divide by 3 (we are trying to get q by itself)
q = 16
----
To check if your solution is correct, you replace the value (16) of the variable (q) within the original equation:
3 (16 − 7) = 27
Following PEMDAS you get:
3(9) = 27
27 = 27 (meaning that the solution is correct)

Compound interest is computed on the principal as well as the interest accumulated over the preceding period. It differs from simple interest in that interest is not added to the principal when computing interest for the next month.
Compound annual growth rate (CAGR) is the average yearly growth rate of an investment over a time period greater than one year. It is one of the most reliable methods for calculating and determining returns for individual assets, investment portfolios, and anything else whose value might grow or decline over time.
The formula to calculate the value of the Mustang after one year is:
value_after_one_year = value_initial * (1 - 0.24)
Plugging in the given values:
value_after_one_year = $32,000 * (1 - 0.24)
= $32,000 * 0.76

14x + 5y = 975
10x + 4y = 750
small ad: $
full-page ad: $
On solving the linear equations 14x + 5y = 975 and 10x + 4y = 750, the price for small ad and full page ad is obtained as $25 and $125 respectively.
What is a linear equation?
A linear equation is one that has a degree of 1 as its maximum value. No variable in a linear equation, thus, has an exponent greater than 1. A linear equation's graph will always be a straight line.
The two linear equations given are -
14x + 5y = 975 .... (1)
10x + 4y = 750 .... (2)
Here, x represents the price of small ad and y represents the price of a full-page ad.
To get the value of x and y solve the system of linear equations -
Multiply equation (1) by 4 and (2) by 5 -
4 (14x + 5y) = 4 × 975
56x + 20y = 3900 .... (3)
5 (10x + 4y) = 5 × 750
50x + 20y = 3750 .... (4)
Subtract equation (4) from (3) -
56x + 20y - (50x + 20y) = 3900 - 3750
56x + 20y - 50x - 20y = 3900 - 3750
6x = 150
x = 150/6
x = 25
Substitute the value of x in equation (1) -
14(25) + 5y = 975
350 + 5y = 975
5y = 975 - 350
5y = 625
y = 625/5
y = 125
So , the prices of small ad is $25 and prices of full-page ad is $125.
Therefore, the values for x and y are $25 and $125 respectively.

give f(x)= 3x + 5, describe how the graph of g compares with the graph of f
The function g(x) = (3x + 5) + 8 is a translation of 8 units upwards of f(x).
How does g(x) compares to f(x)?For a general function f(x), we define a vertical translation of N units as:
g(x) = f(x) + N
if N > 0, then the translation is upwards.
if N < 0, then the translation is downwards.
For a general function f(x), we define a horizontal translation of N units as:
g(x) = f(x) + N
if N > 0, then the translation is to the left.
if N < 0, then the translation is to the right.
Here we start at:
f(x) = 3x + 5

a) The slope is 1
b) The equation of the tangent line is x-y=20.
What is slope?
Slope is calculated using the slope of a line formula, the ratio of "vertical change" to "horizontal change" between two different locations on a line is determined. The difference between the line's y and x coordinate changes is known as the slope of the line.Any two distinct places along the line can be used to determine the slope of any line.
a) To find the slope of the curve, the derivative of a function f(x) at the given point is a slope of the curve
Slope of the given curve y = x at the point P(25, 5) is the derivative f'(x) at P(25,5)
=>m = f'(x) = dy/dx
=>1
Since the derivative of x is 1
f'(x) at P(25, 5) is 1
= > Slope = 1
b) To find an equation of the tangent line at P (25,5) for the curve y = x.
The equation of tangent line in for the function f(x) at P ([tex]x_1,y_1[/tex]) is (y - [tex]y_1[/tex]) = m (x - [tex]x_1[/tex])
Given:
[tex]x_1[/tex] = 25 and [tex]y_1[/tex] = 5, f(x) =x and slope of tangent m = 1
The equation of the tangent line is (y - 19) = - 24(x - 2)
⇒ y - 5 = 1(x -25)
=> y=x-25+5
=> y=x-20
=> x-y=20
The equation of tangent is x-y=20.

In mathematics, a function is a unique arrangement of the inputs (also referred to as the domain) and their outputs (sometimes referred to as the codomain), where each input has exactly one output and the output can be linked to its input.
The given function is f(x) = -5(4)x - 10
On solving the function it gives -
f(x) = -20x - 10
The graph for the function is plotted.
The end behavior of a function f(x) describes the behavior of the function as x approaches +∞ and as x approaches -∞.
Since the leading term of the polynomial (the term in the polynomial which contains the highest power of the variable) is -20x, the degree is 1, i.e. odd, and the leading coefficient is -20, i.e. negative.
This means that function f(x) approaches ∞ as x approaches -∞, and f(x) approaches -∞, as x approaches ∞.
Therefore, the end behaviour is [x→∞,f(x)→-∞] and [x→-∞,f(x)→∞].

tape timer creates dots at a rate of 28 hz, what time interval in seconds does 3 successive dots represent?
Hz (Hertz) is a unit of frequency, which measures the number of events or occurrences of a certain phenomenon per second. In this case, the tape timer creates 28 dots per second, which means that the frequency of dot creation is 28 Hz.
To find the time interval between 3 successive dots, we need to calculate the time it takes for the tape timer to create 3 dots. This can be done by dividing the total time by the number of dots created.
Since the tape timer creates 28 dots per second, the time interval between 3 dots can be calculated as follows:
Time interval = 1 second / 28 dots = 1/28 seconds
So, the time interval between 3 successive dots created by the tape timer is 1/28 seconds, which is the amount of time that elapses between the creation of each dot.

y^2(4-y^2) critical points
The critical values of the given function are 0, +2, and -2.
According to the question
Given function f(x) = y^2(4-y^2)
Setting the partial derivatives of the function y2(4-y2) to zero and solving for y will reveal where the function's crucial points are.
The partial derivatives of y^2(4-y^2) with respect to y are:
⇒ d/dy (y^2) = 2y
⇒ d/dy (4-y^2) = -2y
⇒ d/dy (y^2(4-y^2)) = 2y(-2y) + 2(y^2)
⇒ -4y^2 + 4y^2 = 0
Setting the partial derivative equal to zero:
-4y^2 + 4y^2 = 0
Solving for y:
y = 0 or y = ±2
The critical values are therefore y = 0 and y = 2. Using the second derivative test or by examining the behavior of the function close to these locations, these key points can be categorized as local minima, local maxima, or inflection points.
