Answer:
[tex]x=\frac{9}{16}y^2[/tex]Step-by-step explanation:
Since the vertex of the parabola at the origin (h,k) is (0,0). The standard form of the parabola is represented as:
[tex]\begin{gathered} x=a(y-k)^2+h \\ \end{gathered}[/tex]If the parabola passes through the point (9,-4), we can substitute for (x,y) and (h,k) and solve for ''a.'' and determine the equation:
[tex]\begin{gathered} 9=a(-4-0)^2+0 \\ 9=a(16)+0 \\ a=\frac{9}{16} \\ \end{gathered}[/tex]Then, the equation of the parabola in standard form would be:
[tex]x=\frac{9}{16}y^2[/tex]Factoring the expression 24a63 – 20a%b2 + 4a3b2 gives a new expression of the formUa" by (Wa? + Vb+ 2), where U > 0.What is the value of U?1What is the value of W?What is the value of V?What is the value of Z?What is the value of c?What is the value of y?

Write –9 43/100 as a decimal number
Let's rewrite the mixed number as a fraction, using the following formula:
[tex]a\frac{b}{c}=\frac{a\cdot c+b}{c}_{}[/tex]So:
[tex]-(9\frac{43}{100})=-(\frac{9\cdot100+43}{100})=-(\frac{900+43}{100})=-\frac{943}{100}[/tex]To write -943/100 we can use long division, or since we are dividing by 100 we can simply move the decimal point two units to the left, so:

A passcode to enter a building is a sequence of 4 single digit numbers (0-9), and repeated digits aren'tallowed.Suppose someone doesn't know the passcode and randomly guesses a sequence of 4 digits.What is the probability that they guess the correct sequence?
ANSWER
0.0001984
EXPLANATION
There are 10 possible values for each digit of the passcode to enter the building.
These include: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.
So, there are:10 x 10 x 10 x 10 = 10^4 = 10,000 total possible passcodes.
For no repeat passcode
We have: 10 x 9x 8 x7 = 5040 total possible passcodes without repetition.
Probability of guessing correct sequence
Since there is only 1 correct sequence of 4 digits passcode (without repetition) to enter the building
[tex]\begin{gathered} Prob\text{ = }\frac{1}{5040} \\ Prob\text{ = 0.0001984} \end{gathered}[/tex]Hence, the probability that they guess the correct sequence is 0.0001984

Answer
(a) 80 degrees = (4π/9) radians = 0.444π radians = 1.397 radians.
(b) 120 degrees = (2π/3) radians = 0.667π radians = 2.095 radians.
(c) 90 degrees = (π/2) radians = 0.50π radians = 1.571 radians.
(d) 270 degrees = (3π/2) radians = 1.50π radians = 4.714 radians.
(e) 135 degrees = (3π/4) radians = 0.75π radians = 2.357 radians.
Explanation
To do degree to radians conversion, we need to first note that
360° = 2π radians
So, for each of these cases, if we let the value of the angle given in degree be x in radians, then we can easily solve for x for each ot them
(a) 80 degrees
80° = x radians
360° = 2π radians
We can write a mathematical relationship by cross multiplying
(360) (x) = (80) (2π)
360x = 160π
Divide both sides by 360
(360x/360) = (160π/360)
x = (4π/9) = 0.444π
80° = (4π/9) radians = 0.444π radians = 1.397 radians
(b) 120 degrees
120° = x radians
360° = 2π radians
We can write a mathematical relationship by cross multiplying
(360) (x) = (120) (2π)
360x = 240π
Divide both sides by 360
(360x/360) = (240π/360)
x = (2π/3) = 0.667π
120° = (2π/3) radians = 0.667π radians = 2.095 radians
(c) 90 degrees
90° = x radians
360° = 2π radians
We can write a mathematical relationship by cross multiplying
(360) (x) = (90) (2π)
360x = 180π
Divide both sides by 360
(360x/360) = (180π/360)
x = (π/2) = 0.50π
90° = (π/2) radians = 0.50π radians = 1.571 radians
(d) 270 degrees
270° = x radians
360° = 2π radians
We can write a mathematical relationship by cross multiplying
(360) (x) = (270) (2π)
360x = 540π
Divide both sides by 360
(360x/360) = (540π/360)
x = (3π/2) = 1.50π
270° = (3π/2) radians = 1.50π radians = 4.714 radians
(e) 135 degrees
135° = x radians
360° = 2π radians
We can write a mathematical relationship by cross multiplying
(360) (x) = (135) (2π)
360x = 540π
Divide both sides by 360
(360x/360) = (270π/360)
x = (3π/4) = 0.75π
135° = (3π/4) radians = 0.75π radians = 2.357 radians

Emma wants to advertise how many chocolate chips are in each Big Chip cookie at her bakery. She randomly selects a sample of 64 cookies and finds that the number of chocolate chips per cookie in the sample has a mean of 8.3 and a standard deviation of 2.3. What is the 99% confidence interval for the number of chocolate chips per cookie for Big Chip cookies? Assume the data is from a normally distributed population. Round answers to 3 decimal places where possible. < μ <
Answer:
The 99% confidence interval is
7.558 - 9.042
Explanation:
The formula for the confidence interval is:
[tex]Confidence\text{ }interval=\bar{X}\pm\frac{\sigma}{\sqrt{n}}[/tex]Where:
X is the mean
σ is the standard deviation
z is the z-score for the confidence interval
n is the sample size.
Also, the interval has:
[tex]Upper\text{ }limit=\bar{X}+\frac{\sigma}{\sqrt{n}}[/tex][tex]Lower\text{ }limit=\bar{X}-\frac{\sigma}{\sqrt{n}}[/tex]Then, in this case,
The sample size is n = 64
The mean is X = 8.3
The z-score for a 99% confidence interval is z = 2.58
The standard deviation is σ = 2.3
Then:
[tex]Lower\text{ }limit=8.3-2.58\cdot\frac{2.3}{\sqrt{64}}=9.04175[/tex][tex]Upper\text{ }limit=8.3+2.58\cdot\frac{2.3}{\sqrt{64}}=7.55825[/tex]Thus, the confidence interval, rounded to 3 decimals is
7.558 - 9.042

Please provide an image of the question. If you still want an explanation for problem 13, please don't close the session before I am done with the session.
In our previous session we were analysing the following absolute value equation when the session was abruptly closed:
3 | - 8 x | + 8 = 80
we subtracted 8 to both sides to isolate the term in "x" on the left
3 | - 8 x | = 80 - 8
3 | - 8 x| = 72
divide both sides by 3:
|- 8 x| = 72 / 3
|- 8 x| = 24
Now remove the absolute value bars considering:
1) That the expression inside it is POSITIVE so we DON'T change anything when removing the bars:
- 8 x = 24
now we divide boths sides by "- 8"
x = 24 / (- 8)
x = - 3
Then, when x = -3 notice that the expression - 8 x becomes -8 * (-3) = 24
corroborating that the expression inside the bars was a posotive number.
2) Considering the case that "- 8 x" is NEGATIVE , then when removing the absolute value bars we CHANGE the sign of the expression into:
8 x
Then we have:
8 x = 24
divide by 8 both sides
x = 24 / 8
x = 3
Then we have TWO answers to this equation:
x = -3 and x = 3
both satisfy the equation.

Then write the equation in slope-intercept form. (10,80) (15,95)
We know that the line passes through the points (10,130) and (20,200).
First, we have to find the slope with the following formula

[tex]\begin{gathered} x_1=10 \\ ^{}x_2=15^{} \\ y_1=80 \\ y_2=95 \end{gathered}[/tex]Replacing these coordinates, we have
[tex]m=\frac{95-80}{15-10}=\frac{15}{5}=3[/tex]The slope is 7.

Answer:
Explanation:
Here, we want to fill the sequence, write the recursive and explicit formulae
From the sequence, we can see that each of the numbers are perfect squares
Depending on the term, the number is squared
Take for example, 1^2 is 1, 2^2 is 4
The correct way of filling is thus to raise the term number to 2
So, we have to fill for the 4th term, the 6th term, the 7th term and the 8th term
We have that as follows:
[tex]\begin{gathered} 4thterm=4^2\text{ = 16} \\ 6thterm=6^2\text{ = 36} \\ 7thterm=7^2\text{ = 49} \\ 8thterm=8^2\text{ = 64} \end{gathered}[/tex]The sequence can then be written as:
[tex]1,4,9,16,25,36,49,64,81[/tex]Now, we want to write the explicit and recursive formula
The explicit formula is written in a way that it does not consider the term before the present term
We can easily write that as:
[tex]T_n=n^2[/tex]For the recursive formula, we write it as a mathematical function that takes into account the term before or after the current term
A point to note that there are odd number differences that increase by 3 as we move from term to term
We can see that:
Term 2 minus Term 1 is 3
Term 3 minus Term 2 is 5
Term 4 minus Term 3 is 7
Term 5 minuus Term 4 is 9
Thus, we have the recursive formula as:

ANSWER
Linear function
EXPLANATION
6) To solve this, we have to observe the given data.
Notice that as each term comes, the circles are dropped by a specific factor:
Term 1: 16
Term 2: 8
Term 3: 4
Term 4: 2
Therefore, we see that the number of circles reduces by a certain factor which is ¹/ ₂.
Hence, there is a proportional relationship between the term and the number of circles.
Therefore, a proportional function will be used to model the pattern:
[tex]y=\frac{1}{2}x[/tex]This is also the form of a linear function without the constant. Hence, the answer is a linear function.

x = the final concentration of HCL
Let's find x,
[tex](0.375)(\frac{25}{100})\text{ + (0.625)(}\frac{65}{100})\text{ = (x)}(0.375\text{ + 0.625)}[/tex][tex](0.375)(0.25)\text{ + (0.625)(0.65) = (x)(}1)[/tex][tex]0.09375\text{ + 0.40625 = x}[/tex][tex]0.5\text{ = x }\rightarrow\text{ x = 0.5}[/tex][tex]\text{ x = 0.5 x 100 = 50\%}[/tex]Therefore, the final concentration of the mixed solution is 50%.

−4 3/4=x−1 1/5
What is the solution to the equation?
Enter your answer as a simplified mixed number in the box.
X= ??
The solution to the equation is x = -71/20 i.e.
x = -3(11/20).
Given, an equation
-4(3/4) = x - 1(1/5)
On solving the mixed fraction, we get
-19/4 = x - 6/5
On adding 6/5 both the sides, we get
-19/4 + 6/5 = x
x = (-95 + 24)/20
x = -71/20
On converting the fraction into mixed fraction, we get
x = -3(11/20)
Hence, the solution to the equation is x = -71/20 i.e. x = -3(11/20).

Use the information given to enter an equation in standard form.Slope is 4, and (3,6) is on the line.
Answer
The equation in the point slope form
y - 6 = 4 (x - 3)
Simplifying further,
y - 6 = 4x - 12
y = 4x - 12 + 6
y = 4x - 6
OR
y - 4x = -6
OR
-4x + y = -6
OR
-4x + y + 6 = 0
Explanation
The general form of the equation in point-slope form is
y - y₁ = m (x - x₁)
where
y = y-coordinate of a point on the line.
y₁ = This refers to the y-coordinate of a given point on the line
m = slope of the line.
x = x-coordinate of the point on the line whose y-coordinate is y.
x₁ = x-coordinate of the given point on the line
For this question,
Slope = m = 4
(x₁, y₁) = (3, 6)
x₁ = 3
y₁ = 6
y - y₁ = m (x - x₁)
y - 6 = 4 (x - 3)
Simplifying further,
y - 6 = 4x - 12
y = 4x - 12 + 6
y = 4x - 6

Graph ABCD with vertices B(2, 1), C(4,4) and D(4,0) and its image after the reflection in the line n: x=0.
We have a triangle BCD with vertices
[tex]\lbrace(2,1),(4,4),(4,0)\rbrace[/tex]The transformation is a reflection in the line x = 0(also know as the y-axis). A reflection on the y-axis is given by the following transformation:
[tex](x,y)\rightarrow(-x,y)[/tex]Doing this transformation on each one of our vertices, we can find the transformed figure.
[tex]\begin{gathered} (2,1)\rightarrow(-2,1) \\ (4,4)\rightarrow(-4,4) \\ (4,0)\rightarrow(-4,0) \end{gathered}[/tex]Then, the image is
[tex]\lbrace(-2,1),(-4,4),(-4,0)\rbrace[/tex]The option that fits this transformation is option b.
