Step-by-step explanation:
Any equation that is equivalent to V = x(12 - 2x)(8 - 2x) is accepted. Any graph that is similar to the graph of the function is accepted.
Sample Student Response:
The box is a cube, so the volume is the length × width × height. The height is the side length of the cardboard, which is x.
The length is the original length minus two side lengths of the cutout, so the length is 12 - 2x.
Similarly, the width is the original width minus two side lengths of the cutout, so the width is 8 - 2x.

Find the first six terms of the sequence.
a1 = -1, an = 2 • an-1
Answer:
The first six terms of the sequence are: -1, -2, -4, -8, -16 and -32
Step-by-step explanation:
The sequence is:
[tex]a_1=-1\\a_n=2*a_{n-1}[/tex]
So, for finding the first six terms of the sequence, we need to replace n by the numbers 1 to 6 and we get:
[tex]a_1=-1\\a_2=2*a_{2-1} =2*a_1\\a_3=2*a_{3-1} =2*a_2\\a_4=2*a_{4-1} =2*a_3\\a_5=2*a_{5-1} =2*a_4\\a_6=2*a_{6-1} =2*a_5\\[/tex]
That means that the term n is 2 times the last term. Then, replacing the values of [tex]a_1, a_2, a_3, a_4[/tex] and [tex]a_5[/tex], we get:
[tex]a_1=-1\\a_2=2*(-1)=-2\\a_3=2*(-2)=-4\\a_4=2*(-4)=-8\\a_5=2*(-8)=-16\\a_6=2*(-16)=-32\\[/tex]
So, The first six terms of the sequence are: -1, -2, -4, -8, -16 and -32

When a ball is dropped from a state of rest at time t=0t=0, the distance, measured in feet, that it has traveled after tt seconds is given by the formula s(t)=16t2s(t)=16t2 . (use decimal notation. if necessary, give your answer rounded to two decimal places.) (a) how far does the ball travel during the time interval [3, 3.5 ]? distance = .5 feet (b) compute the average velocity over the time interval [3, 3.5 ]. average velocity = 104 feet/sec (c) by computing the average velocity over the time intervals [3, 3.1 ], [3, 3.01 ], and [3, 3.001 ], . . . , estimate the ball's instantaneous velocity at t=3t=3. instantaneous velocity = feet/sec?
Part A. To solve for the distance travelled during the interval, all we have to do is to plug in values of t = 3 and t = 3.5 in the equation and the difference would be the answer:
when t = 3: s = 16 (3)^2 = 144 m
when t = 3.5: s = 16 (3.5)^2 = 196 m
Therefore the distance travelled within the interval is:
196 m – 144 m = 52 m
Part B. The velocity is calculated by taking the 1st derivative of the equation. v = ds / dt
s = 16 t^2
ds / dt = 32 t = v
when t = 3: v = 32 (3) = 96 m / s
when t = 3.5: v = 32 (3.5) = 112 m / s
Therefore the average velocity is:
(96 + 112) /2 = 104 m / s
Part C. We can still use the formula v = 32 t and plug in the value of t = 3
v = 32 t = 32 (3)
v = 96 m / s
To calculate the distance and velocities for the ball in question, we use the formula s(t)=16t^2, calculate differences, and use limits as the intervals approach an instant.
Explanation:The formula s(t)=16t2 gives the distance s(t) in feet that a ball has traveled after t seconds when dropped from a state of rest. To find the distance during the time interval [3,3.5], we calculate s(3.5) and s(3), and then find the difference: s(3.5) = 16 × (3.5)2 and s(3) = 16 × (3)2.
The average velocity over the interval [3,3.5] is the change in distance divided by the change in time, which is computed as ∆ s/ ∆ t.
For the instantaneous velocity at t=3, we compute the average velocities over smaller and smaller intervals approaching the instant t=3. As these intervals become smaller, the average velocity approaches the instantaneous velocity.

Based on these data, is it better to describe the centers of distribution in terms of the mean or the median? Why? Select the correct answer below
It's better to describe the center of distribution in Bakery A using the mean because the data is symmetric, while for Bakery B, the median is preferred due to asymmetric data.
To determine whether it's better to describe the centers of distribution in terms of the mean or the median for each bakery, we need to consider the shape of the data distribution.
For Bakery A:
- The data appears to be relatively symmetric, with values ranging from 34 to 61.
- There are no extreme outliers that significantly skew the data.
For Bakery B:
- The data is not symmetric; there is a wide range of values from 10 to 57.
- There is a notable outlier (10) that is much lower than the rest of the data.
Given these observations:
- For Bakery A, since the data is symmetric and there are no significant outliers, the mean (average) would be an appropriate measure of the center.
- For Bakery B, because the distribution is not symmetric and there is a significant outlier, the median (middle value) would be a more robust measure of the center.
So, the correct answer is:
C) Mean for Bakery B because the data is symmetric; median for Bakery A because the data is not symmetric.
Complete Question:
The number of bagels sold daily for two bakeries is shown in the table:
Bakery A 45 52 51 48 61 34 55 46
Bakery B 48 42 25 45 57 10 43 46
Based on these data, is it better to describe the centers of distribution in terms of the mean or the median? Explain.
A) Mean for both bakeries because the data is symmetric
B) Median because the distribution is not symmetric for both bakeries
C) Mean for Bakery B because the data is symmetric; median for Bakery A because the data is not symmetric
D) Mean for Bakery A because the data is symmetric; median for Bakery B because the data is not symmetric
The correct answer is B): Median because the distribution is not symmetric for both bakeries.
Let's first calculate the mean and median for each bakery:
Bakery A:
Data: 45, 52, 51, 48, 61, 34, 55, 46
Mean (average):
[tex]\[ \text{Mean} = \frac{45 + 52 + 51 + 48 + 61 + 34 + 55 + 46}{8} = \frac{392}{8} = 49 \][/tex]
Median (middle value):
Arrange the data in ascending order: 34, 45, 46, 48, 51, 52, 55, 61
[tex]\[ \text{Median} = \frac{48 + 51}{2} = 49.5 \][/tex]
For Bakery A, the mean is 49 and the median is 49.5. The median (49.5) is slightly higher than the mean (49), indicating a slight right skew in the data.
Bakery B:
Data: 48, 42, 25, 45, 57, 10, 43, 46
Mean (average):
[tex]\[ \text{Mean} = \frac{48 + 42 + 25 + 45 + 57 + 10 + 43 + 46}{8} = \frac{316}{8} = 39.5 \][/tex]
Median (middle value):
Arrange the data in ascending order: 10, 25, 42, 43, 45, 46, 48, 57
[tex]\[ \text{Median} = \frac{43 + 45}{2} = 44 \][/tex]
For Bakery B, the mean is 39.5 and the median is 44. The mean (39.5) is lower than the median (44), indicating a left skew in the data.
Bakery A: The median (49.5) is slightly higher than the mean (49), suggesting a slight right skew. Given this slight skewness, the median might be a better measure of central tendency for Bakery A.
Bakery B: The mean (39.5) is noticeably lower than the median (44), indicating a left skew. Therefore, the median would likely be a better measure of central tendency for Bakery B.
Based on this analysis, the correct answer is B): Median because the distribution is not symmetric for both bakeries.

The graph of f(x) = x2 is shifted 3 units to the right to obtain the graph of g(x). Which of the following equations best describes g(x)?
a. g(x) = (x + 3)2
b. g(x) = x2 − 3
c. g(x) = x2 + 3
d. g(x) = (x − 3)2
Answer: Option 'd' is correct.
Step-by-step explanation:
Since we have given that
[tex]f(x) = x^2[/tex]
We need to shift the function f(x) 3 units to the right to obtain the graph of g(x).
As we know that shifting right is the horizontal shift.
And f(x-h) = g(x) , here f shift right h units.
so, After shifting 3 units right, we get that
[tex]g(x)=(x-3)^2[/tex]
Hence, Option 'd' is correct.

Parallel lines are those two lines that are always the same distance apart and never touch.
then, by the definition of parallel lines and labeling angles
DE be the line passing through B, parallel to AC, with angles as labelled in the figure as shown below in the attachment.
Alternative Interior Angle theorem states that the angles that are formed on opposite sides of the transversal and inside the two lines are alternate interior angles also this theorem says that when the lines are parallel, then the alternate interior angles are equal.
Then,
[tex]\angle 1 \cong \angle 4[/tex] and
[tex]\angle 3 \cong \angle 5[/tex] [By Alternative Interior angle theorem]
Angles are always congruent if their measures in degrees are equal.
therefore,

[tex]m\angle 3=m\angle 5[/tex] [By Congruent Angle have equal measure] ......[1]
Straight Angles states that angles on one side of a straight line always add to 180 degrees.
From the given figure;
By the addition angle and definition of straight angle we get;
[tex]m\angle 4 +m\angle 2 +m\angle 5 =180^{\circ}[/tex] ......[2]
Substituting equation [1] in [2] we get;
[tex]m\angle 1 +m\angle 2 +m\angle 3 =180^{\circ}[/tex]
Therefore, the sum of the interior angles measures of triangle ABC is [tex]180^{\circ}[/tex]

Solve by factoring c^2=5c
The solutions to the equation c² = 5c are c = 0 and c = 5.
We have,
To solve the equation c² = 5c by factoring,
we can rearrange it as:
c² - 5c = 0
Then we can factor out the common factor of c, giving:
c(c - 5) = 0
Now we can apply the zero product property, which states that if the product of two factors is equal to zero, then at least one of the factors must be zero.
So we have:
c = 0 or c - 5 = 0
Solving for c in each case, we get:
c = 0 or c = 5
Therefore,
The solutions to the equation c² = 5c are c = 0 and c = 5.

What is the difference between rational functions and inverse variation
Rational functions are functions that can be written as the ratio of two polynomial functions, while inverse variations are a type of rational function where the product of two varying quantities is a constant.
Explanation:A rational function is any function that can be written as the ratio of two polynomial functions. Both the numerator and the denominator are polynomials. For example, f(x) = (2x^2 + 3)/(x - 5) is a rational function where 2x^2 + 3 and x - 5 are polynomial functions.
On the other hand, an inverse variation, or inverse proportion, is a specific type of rational function where the product of two varying quantities is a constant. It is in the form of y = k/x, where k is a nonzero constant. For example, if y varies inversely as x, then the product of x and y is constant, which means xy = k.
To summarize, all inverse variations are rational functions since they can be expressed as a ratio of two polynomials. However, not all rational functions are inverse variations since not all can be written in the form y = k/x.
