in class, michael and kayla were working together on the following problem in class: find sx 3√3 −2x dx. (a) kayla says, "u should be (3 −2x) because i always pick the most inside factor of a function as my u." i. will kayla’s substitution work in this case? explain your reasoning. ii. does kayla’s idea work for all u-substitutions (if it does explain, if not give an example were it does not)? (b) michael says the u should be 3√3 −2x because i always pick the most complicated factor of a function as my u." i. will michael’s substitution work in this case? explain your reasoning. ii. does michael’s idea for all u-substitutions (if it does explain, if not give an example were it does not)?
Answers
a. If we let u = (3 - 2x), then the derivative du/dx would be -2, which is not equal to zero. This indicates that the substitution does not satisfy the requirement for u to be differentiable.
b. Michael's substitution satisfies the requirement for u to be differentiable.
(a) i. Kayla's proposed substitution of u as (3 - 2x) will not work in this case. The reason is that when using the u-substitution method, it is necessary for the chosen u to be differentiable, meaning that its derivative du/dx should exist and be non-zero. However, if we let u = (3 - 2x), then the derivative du/dx would be -2, which is not equal to zero. This indicates that the substitution does not satisfy the requirement for u to be differentiable.
ii. Kayla's idea of always picking the most inside factor as u does not work for all u-substitutions. There can be cases where choosing the most inside factor may not lead to a valid substitution that simplifies the problem or makes integration easier. It is important to consider the properties of the function and choose a suitable substitution accordingly.
(b) i. Michael's proposed substitution of u as 3√3 - 2x will work in this case. If we let u = 3√3 - 2x, then the derivative du/dx would be -2, which is non-zero. Therefore, Michael's substitution satisfies the requirement for u to be differentiable.
ii. Michael's idea of always picking the most complicated factor as u also does not hold true for all u-substitutions. The choice of u depends on various factors, including the structure of the function, simplification possibilities, and making the integration process more manageable. It is not necessarily the case that the most complex factor will always result in a successful substitution.
It is important to consider the specific characteristics of the function and apply appropriate judgment in choosing the substitution u to simplify the problem effectively.

Your club has been asked to contribute to a service project benefiting a local charitable organization. You plan to buy a combination of $5 and $10 gift cards to donate. You plan to buy exactly 20 gift cards and want to spend between $150 and $160. What are the possible combinations of $5 and $10 gift cards your club can purchase? (Write a compound inequality in one variable to solve this problem).
Answers
Answer:
the possible combinations of $5 and $10 gift cards your club can purchase are :
eight $5 gift cards and twelve $10 gift cards
nine $5 gift cards and eleven $10 gift cards
or ten each of $5 gift cards and $10 gift cards
Step-by-step explanation:
From the information given:
You plan to buy a combination of $5 and $10 gift cards
You plan to buy exactly 20 gift cards and want to spend between $150 and $160.
The objective is to determine the possible combinations of $5 and $10 gift cards your club can purchase?
Let assume the g is the number of the $5 gift cards bought;
then (20 - g) will be the number of the $10 gift card bought.
Thus; the compound inequality for the amount spent between $150 and $160 will be:
= 150 ≤ 5g + 10(20 - g) ≤ 160
= 150 ≤ 5g + 200 - 10g ≤ 160
= 150 ≤ 5g -10 g + 200 ≤ 160
= 150 ≤ -5g + 200 ≤ 160
= 150-200 ≤ -5g ≤ 160 -200
= -50 ≤ -5g ≤ -40
Divide through by -5
= 10 ≥ g ≥ 8
= 8 ≤ g ≤ 10
Thus; the possible combinations of $5 and $10 gift cards your club can purchase are :
eight $5 gift cards and twelve $10 gift cards = i.e 8 ×$5 + 12 ×$10
= $40+$120
=$160
nine $5 gift cards and eleven $10 gift cards
= 9 ×$5 + 11 ×$10
= $45 + $110
= $155
or ten each of $5 gift cards and $10 gift cards
= 10 ×$5 + 10 ×$10
= $50 + $100
= $150
These combinations falls in between the range of $150 and $160.

PLEASE PLEASE PLEASE HELP!!!
Answers
Answer:
I think it's y < 3x +1
Step-by-step explanation:
subtract 6x to the right side. that's -2y > -6x - 2. then divide -2 out of y, now you have to flip the sign. Now you have y < 3x + 1
Answer:
The inequality into slope Intercept form is:
\(y<3x+1\)Step-by-step explanation:
We know that the slope-intercept form of a linear function is
\(y = mx+b\)
where
m is the slope b is the y-interceptGiven the inequality
\(6x-2y>\:-2\)
subtract 6x from both sides
\(6x-2y-6x>-2-6x\)
Simplify
\(-2y>-2-6x\)
Multiply both sides by -1 (reverses the inequality)
\(\left(-2y\right)\left(-1\right)<-2\left(-1\right)-6x\left(-1\right)\)
Simplify
\(2y<2+6x\)
Divide both sides by 2
\(\frac{2y}{2}<\frac{2}{2}+\frac{6x}{2}\)
\(y<3x+1\)
Therefore, the inequality into slope Intercept form is:

The function of the given graph is y = 5x⁵. The graph of a polynomial function shows the given behavior if the power is the odd value(n = 5).
What is the general form of a graph with a polynomial function?The general form of a graph with a polynomial function is y = aₙxⁿ. Where 'n is odd'
If aₙ > 0; then the behavior of the graph on the left and right sides are given by \(\lim_{x \to -\infty} f(x) =-\infty\) and \(\lim_{x \to \infty} f(x) =\infty\) respectively.
If aₙ < 0; then the behavior of the graph on the left and right sides are given by \(\lim_{x \to -\infty} f(x) =\infty\) and \(\lim_{x \to \infty} f(x) =-\infty\) respectively.
Calculation:From the given graph's behavior,
Left side: \(\lim_{x \to -\infty} f(x) =-\infty\) and
Right side: \(\lim_{x \to \infty} f(x) =\infty\)
So, the coefficient aₙ is aₙ > 0. So, it may be 4 and 5.
Since the power of the variable x is n is odd, the equation of the given graph is y = 5x⁵.

Which statement best explains if the graph correctly represents the proportional relationship y = 0.5x? (4 points) A coordinate plane is shown. Points are graphed at 1 comma 0.5 and 4 comma 2. The points are joined by a line.
Answers
The correct statement is (A) the points on the line would indeed be a part of the equation y = 0.5x.
What are proportional relationships?Relationships between two variables that are proportional occur when their ratios are equal.
Another way to consider them is that in a proportionate relationship, one variable is consistently equal to the other's constant value.
The "constant of proportionality" is the name of this constant.
Observing the graph, the line traverses (0, 0). We obtain y=0.5(0)=0 if x=0.
Since this is the point's y-coordinate, it passes through this.
Y=mx+b, where m is the slope and b is the y-intercept, is the slope-intercept form equation for this line.
m=0.5 and b=0 in this equation.
This indicates that the slope is 0.5 or 1/2; as slope = rise/run, this indicates that the line rises one for every increase in the horizontal dimension of two.
This implies that starting from (0, 0), we would climb 1 and cross 2 to make the spot (2, 1).
When examining the graph, the line passes through this location.
We would then ascend 1 and cross over 2 once more to (4, 2). Once more, the line passes through this spot.
Therefore, the correct statement is (A) the points on the line would indeed be a part of the equation y = 0.5x.

Find 0.3% of 60.
help pleaseee
Answers
0.003 * 60 = 0.18
Solution: 0.18
0.3 percent of 60 is 0.18.
To find 0.3 % of 60, we can convert 0.3 % to decimal form by dividing it by 100: 0.3 ÷ 100 = 0.003.
Next, we multiply 0.003 by 60 to calculate the desired percentage:
0.003 * 60 = 0.18.
Therefore, 0.3% of 60 is 0.18. This means that if we take 0.3% (0.003) of the value 60, the result is 0.18. It can also be interpreted as 0.18 being 0.3% of 60. By converting the percentage to decimal form and multiplying it by the given value, we obtain the corresponding portion or fraction of the whole.

7. Find the coordinates of a point on a circle with radius 20 corresponding to an angle of \( 305^{\circ} \)
Answers
Given that a circle with radius 20 has a corresponding angle of 305°.
To find the coordinates of a point on the circle, we use the formula:`(r cos (θ), r sin (θ))`Here, `r = 20` and `θ = 305°`.
Substituting the values of `r` and `θ` in the formula, we get:`(20 cos (305°), 20 sin (305°))`
Using the values of trigonometric ratios, we can write:cos(305°) = cos(360° - 305°) = cos(55°) ≈ -0.5736sin(305°) = sin(360° - 305°) = sin(55°) ≈ 0.8192
Hence, the coordinates of a point on a circle with radius 20 corresponding to an angle of 305° are approximately `(-11.47, 16.38)`.

If 5x + y = 20 and 10x - 2y = 50 are two linear equations in two variables. Find the value of x and y.
x = 1, y = 1
x = 2, y = 1/2
x = 9/2, y = -5/2
x = 1, y = 5/2
Answers
Answer:
x = 9/2, y = -5/2
Step-by-step explanation:
5x + y = 20
10x - 2y = 50
There's multiple ways to do this, but I will solve using substitution.
Isolate variable y on the first equation.
5x + y = 20
y = 20 - 5x
Substitute the value of y for 20 - 5x in the second equation.
10x - 2(20 - 5x) = 50
Use distributive property:
10x - 40 + 10x = 50
Combine like terms:
20x - 40 = 50
20x = 90
x = 90/20
x = 9/2
Substitute x for 9/2 and solve for y:
y = 20 - 5(9/2)
y = 20 - 45/2
y = 40/2 - 45/2
y = -5/2
Answer:
x =9/2, y = -5/2
Step-by-step explanation:
5(9/2) + -(5/2)= 20
45/2 + -5/2 = 20
40/2 = 20
10(9/2) - 2(-5/2) = 50
90/2 + 10/2 = 50

The given scenario describes three independent random variables with n observations each, denoted as xij, where i = 1, 2, 3 and j = 1, 2, ..., n. The expected values of these variables are provided.
In this scenario, we have three random variables, each with n observations. The variable xij represents the jth observation of the ith random variable. For example, x11 would be the first observation of the first random variable, x12 would be the second observation of the first random variable, and so on.
The expected value of a random variable is a measure of its central tendency and represents the average value we would expect to obtain if we were to repeat the experiment many times. In this case, the expected values of the first, second, and third random variables are given, although the specific values are not provided in the question.
Having the expected values allows us to gain insights into the behavior of the random variables. We can compare the observed values of the variables with their respective expected values to assess deviations or patterns. By examining the differences between the observed values and the expected values, we can make inferences about the variables' distributions and identify any relationships between them.
