The features of the given parabola are as follows:
a) Vertex: (3,9).
b) Vertical intercept: y = -9.
c) x-intercepts: (-5.12, 0) and (-0.88, 0).
Features of the quadratic functionThe equation of the parabola is given by:

Hence the coefficients are:
a = -2, b = -12, c = -9.
The formula for the coordinates of the vertex, considering the coefficients of a quadratic equation, is given as follows:

The vertical intercept is given as follows:
f(0) = -2(0)² - 12(0) - 9 = -9.
The roots are given as follows:
[tex]x_{1} = \frac{-b + \sqrt{b^2 - 4ac}}{2a} = \frac{12 + \sqrt{(-12)^2 - 4(-2)(-9)}}{2(-2)} = -5.12[/tex][tex]x_{2} = \frac{-b - \sqrt{b^2 - 4ac}}{2a} = \frac{12 - \sqrt{(-12)^2 - 4(-2)(-9)}}{2(-2)} = -0.88[/tex]Hence the points are:

The values of measure of angle y is found as 65 degrees.
What is defined as the linear pair?Once two lines intersect at a single point, a linear pair of angles is formed. If the angles are adjacent to one another after the two lines intersect, they are said to be linear. The sum of the angles of a linear pair has always been 180°. These angles are also referred to as supplementary angles. A adjacent angles are those that share a vertex. As a result, the linear angles get a common vertex here as well.For the given question;
Line k || Line l
(x + 5) + (3x + 15) = 180 (linear pair)
Solving;
4x + 20 = 180
4x = 160
x = 40
Put the value of x in angles (2x + 30)
2x + 30 = 2×40 + 30 = 110
Now,
2x + 30 = y + (x + 5) (alternate interior angles)
Solving;
110 = y + 40 + 5
y = 110 - 45
y = 65 degrees.
Thus, the values of measure of angle y is found as 65 degrees.

Find the average rate of change of f(x)=x²-4x+1 from x=3 to x=7.
Simplify your answer as much as possible.
( explain pls )
At x=3 to x=7, the average rate of change of the given function
f(x) = x2- 4x + 1 is 6.
Solution:Given function,
f(x) = x² - 4x + 1
given x=3 and x=7
To find the average rate of change of a function, find its slope(m),
To find m ,
m= (y2 - y1) / (x2 - x1)
here y1 and y2 not given.
then substitute the given values of x into f. (x)
when x=3 ,
y1 = (3² - 4×3 +1)
= (9 - 12 +1)
= -2
so (x1,y1) = (3,-2)
similarly to find y2,
substitute x = 7 to f(x)
y2 = (7² - 4×7 + 1)
= (49 - 28 +1)
= 22
so (x2,y2) = (7,22)
To find m, substitute the values.
m= (y2 - y1) / (x2 - x1)
= (22 -( - 2)) / (7 - 3)
= 24/4
= 6
As a result, the average rate of change of the function x2-4x + 1 is 6.

what number is not part of the solution set for the inequality below?3x-18> 1210, 11, 15,8 _
First, let's solve for x in the inequality to find an interval, the options that are not included in the interval are not part of the solution set, we can do it by following these steps:
1. 3x-18> 12 , add 18 on both sides:
3x - 18 + 18 > 12 + 18
3x > 30
2. Divide both sides by 3:
3x/3 > 30/3
x > 10
So, to be a part of the solution, x must be greater than 10, then the interval that represents the solution is (10, ∞). From the given options, the only one that is not included in this interval is 8, because it is less than 10, then the answer is 8.

Which term describes the slope of the line below?
•
A. Undefined
B. Zero
• C. Positive
D. Negative
Answer:
D. Negative
Step-by-step explanation:
The slope is negative because the line goes down from left to right. In other words, as x increases, y decreases.
A slope would be positive when the line goes up from left to right. In other words, as x increases, y increases.
A slope would be zero if the line is horizontal, so as x increases, y remains constant.
A slope would be undefined if the line is vertical. It is undefined because x remains constant while y changes. Lines are functions, which mean for every input there is exactly 1 output. If there are multiple y values for 1 x value, then this is not a function and therefore has an undefined slope.

3. How many tens are there between 9,312 and 9,522? Explain your thinking
The number of tens between the given numbers are 1883.
The number of tens between two numbers can be calculated by the concept of proportions. A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem. Now, to find the number of tens we divide the number by 10. So, the number of tens in the given numbers are
9312/10 = 931 (approximately)
9522/10 = 952 (approximately).
Now, the numbers of tens between the two given numbers can be calculated by adding the number of tens in them that is,
952 + 931 = 1883 tens between the two numbers.

Write the exponential function y - 45(1.085)^t in the form y = ae^kt(a) Once you have rewritten the tormula, give & accurate to at least four decimal places.K=If T is measured in years, indicate whether the exponential function is growing or decaying and find he annual and continuous growth/decay rates. The rates you determine should be positive in the case of growth or decay (by choosing decay the negative rate is implied).(b) The annual (growth/decay) rate is ___ % per yearC) The continuous (growth/decay) rate is ___ % per year
EXPLANATION
Given the exponential function:
45(1.085)^t
We have that 45=a is the initial value and 1.085 is the growth rate,
1.085 - 1 = 0.085* 100 = 8.5 % (This is the growth rate)
Let's compute the function with two values of t, as for instance, t=0 and t=1:
[tex]f(0)=45(1.085)^0=45\cdot1=45\longrightarrow\text{ (0,45)}[/tex][tex]f(1)=45\cdot(1.085)^1=48.825\text{ }\longrightarrow\text{(1,48.825)}[/tex]Now, the function in the form y = ae^kt will be as follows:
[tex]y=45\cdot e^{kt}[/tex]Substituting t by 1:
[tex]y(1)=45\cdot e^k=48.825[/tex]Dividing both sides by 45:
[tex]e^k=\frac{48.825}{45}=1.085[/tex]Applying ln to both sides:
[tex]k=\ln 1.085[/tex]Computing the argument:
[tex]k=0.0816[/tex]The expression will be as follows:
[tex](a)---\longrightarrow y=45e^{0.0816t}[/tex]As this is a growing function, the rates are positive.
The annual growth rate is 8.5% and It's was calculated above.
Now, we need to compute the continuous rate because It's given by the value of k:
k = 0.0816 --> Multiplying by 100 --> 0.0816 * 100 = 8.16%
The continuous growth rate is 8.16%
A manufacturing machine has a 4% defect rate.
If 9 items are chosen at random, what is the probability that at least one will have a defect?
The probability that at least one will have a defect is 19%.
What is probability?
Simply put, probability is the likelihood that something will occur. When we don't know how an event will turn out, we can discuss the likelihood or likelihood of several outcomes. Statistics is the study of events that follow a probability distribution.
By simply dividing the favorable number of possibilities by the entire number of possible outcomes, the probability of an occurrence can be determined using the probability formula.
p = 4% = 0.04
q = Prob of a defective product is 0.03; hence, Prob(non-defective) = 1 - 0.04 = 0.96.
Prob(at least one flaw) is now equal to 1 - Prob (0 defects)
= 1 - 9C0 x 0.04^0 x 0.96^9
= 1 - 1 x 1 x 0.815

Answer:
[tex]y-2=\dfrac{1}{2}(x-6)[/tex]

To find the equation of a line that passes through two given points, first find its slope by substituting the given points into the slope formula.

Define the points:
(x₁, y₁) = (6, 2)(x₂, y₂) = (10, 4)Substitute the points into the slope formula:
[tex]\implies m=\dfrac{4-2}{10-6}=\dfrac{2}{4}=\dfrac{1}{2}[/tex]

In order to do this, we need to know how many kilograms are in one pound: It weighs something about 2.2 pounds.

Which situation yields data with variability?The distance covered by different vehicles traveling at a constant rate of 60 mph for 45 minutes The length of different professional American football fieldsThe weight of 6th grade studentsThe moon cycle duration in a year
Answer:
The weight of 6th-grade students
Explanation:
We have variability if each value in the data is different.
When a vehicle travels at a constant rate for the same amount of time, the distance covered will be always the same. So, this situation doesn't yield data with variability.
In the same way, the length of a professional American football field and the moon cycle duration in a year are standard, they always have the same value so these situations don't yield data with variability.
Finally, each student of 6th grade has a different weight, so this is the situation that yields data with variability.
Therefore, the answer is:
The weight of 6th-grade students
