Choice A
Step-by-step explanation:
To approach this problem, separate out the composite solid figure into individual easily manageable components
At the bottom we have a rectangular prism which has a base length of 2a, a height of a and a width of c
Its volume = L X H X W = 2a·a·c= 2a²c
Plugging in values for a and c we get
Volume of rectangular prism
= 2 x (3.7)² x 2
= 54.76 cubic units
On top of this rectangular prism are two right-angled triangular prisms
The volume of a right-angled triangular prism =
Here height = b (confusing :)
base = a
width = c
So volume of each triangular prism
[tex]=\textrm{$\dfrac{1}{2} \times $ base x height x width}\\\\= \dfrac{1}{2} a \times b \times c\\\\ = \dfrac{1}{2} \times 3.7 \times 5.1 \times 2\\\\= 18.87[/tex]
Since there are 2 such prisms the volume of both

Let W1 be the set: Determine if W1 is a basis for R3 and check the correct answer(s) below. O A. W1 is not a basis because it does not span R3. O B. W1 is a basis. O C. W1 is not a basis because it is linearly dependent.
The set W1 could be a basis for R3 if it spans R3 and is linearly independent, but without the specific elements of W1, it's not possible to determine if it meets those criteria.
The specific elements that make up the set W1. However, I can tell you that to be a basis for R3, a set of vectors must meet two criteria:
The set must span R3, meaning that any vector in R3 can be written as a linear combination of the vectors in the set.The set must be linearly independent, meaning that no vector in the set can be written as a linear combination of the other vectors in the set.So, depending on the specific elements of W1, it could be either A, B, or C.
If the set W1 doesn't span R3, it would be A.
If the set W1 is linearly dependent, it would be C.
If both conditions are met the set is a basis, so the answer would be B.

Adrian grabbed a bag of mandarin oranges off the shelf and spilled them all out on the counter. He divided them into 4 piles, but there was 3 left over. He rearranged them into 5 piles but this time there were 2 left over. Then he tried putting them into six piles, but there were 3 left over. When he tried 7 piles there were 3 left over again. Finally he put them into 3 piles and he didn’t have any left over. If the number of mandarins in the bag was less than 100, how many mandarins were in the bag?
The number of mandarins in the bag is 3 * 33 + 3 = 102 mandarins.
How did we determine the values?This is a Diophantine equation problem, which is a type of mathematical problem that looks for integers that satisfy a given equation.
We know that the number of mandarins in the bag is equal to 4n + 3, 5m + 2 and 6p + 3 and 7q + 3 for some integers n, m, p and q.
We also know that the number of mandarins in the bag is equal to 3r, where r is an integer.
From the information provided, we can set up the following equation:
4n + 3 = 5m + 2 = 6p + 3 = 7q + 3 = 3r
Now we can use the information that when he finally put them into 3 piles and he didn't have any left over, meaning that the number of mandarins in the bag is divisible by 3, we can see that the remaining number in each case is 3.
Thus the number of mandarins in the bag is 3 * (some integer) + 3.
We can then use the information that the number of mandarins in the bag was less than 100, meaning the possible value of r is less than 34.
Testing values of r starting from 1, we can see that r = 33 satisfies the equation and the number of mandarins in the bag is 3 * 33 + 3 = 102 mandarins

a. Write an exponential equation that will represent the number of Root Beer loyalists in Outback for any year.
b. How many Root Beer loyalists should there be as of September 2023? Show or explain how you know.
=========================================================
Explanation:
Part A
x = number of years after 1983
Example: x = 2 is the year 1985 since 1985-1983 = 2.
The number of people who drink this beverage declines by 6.5% each year. The multiplier is 1+r = 1+(-0.065) = 0.935
Meaning that if 6.5% of the people leave, then 93.5% remain. The two percentages add to 100%.
This value 0.935 is the base of the exponent portion. We have 0.935^x as the exponent portion.
Out front is the value 5480 which is the starting amount of people.
This leads to the exponential equation y = 5480*0.935^x
It is of the form y = ab^x
a = 5480 = starting population
b = 0.935 = decay factor
---------------------------------------
Part B
The timespan from 1983 to 2023 is 40 years (because 2023-1983 = 40).
Which means we plug x = 40 into the equation we found in part A.
y = 5480*0.935^x
y = 5480*0.935^40
y = 5480*0.06799303620922
y = 372.601838426526
y = 373
Be sure to round to the nearest whole number.
We expect or predict there will be approximately 373 people who remain loyalists to this root beer as of September 2023.
Answer:
Part (a)
[tex]y=5480(0.935)^x[/tex]
where:
x is the number of years after 1983.y is the total number of Root Beer loyalists.Part (b)
373
Step-by-step explanation:
[tex]\boxed{\begin{minipage}{9 cm}\underline{General form of an Exponential Function}\\\\$y=ab^x$\\\\where:\\\phantom{ww}$\bullet$ $a$ is the initial value ($y$-intercept). \\ \phantom{ww}$\bullet$ $b$ is the base (growth/decay factor) in decimal form.\\\end{minipage}}[/tex]
The initial number of people who drink Root Beer (in September 1983):
a = 5480If the number of people that drink Root Beer instead of Coca-Cola has been declining at the rate of 6.5% per year, then:
b = 100% - 6.5% = 93.5% = 0.935Therefore, an exponential equation that represents the number of Root Beer loyalists in Outback for any year is:
[tex]y=5480(0.935)^x[/tex]
where:
x is the number of years after 1983.y is the total number of Root Beer loyalists.The number of years between September 1983 and September 2023 is:
2023 - 1984 = 40 yearsTo calculate how many Root Beer loyalists should there be as of September 2023, substitute x = 40 into the equation found in part (a):
[tex]\implies y=5480(0.935)^{40}[/tex]
[tex]\implies y=5480(0.0679930362...)[/tex]
[tex]\implies y=372.601838...[/tex]
[tex]\implies y=373[/tex]
Therefore, there should be approximately 373 Root Beer loyalists as of September 2023.

The curve [tex]\(y = x^9\)[/tex] is the upper curve, and it intersects the x-axis at x = 0 and the y-axis at x=1.
So, the limits of integration for x are [tex]\(0 \leq x \leq 1\)[/tex].
2. For y: The curve [tex]\(x = y^9\)[/tex] is the right curve, and it intersects the y-axis at y=0 and the x-axis at y=1.
So, the limits of integration for y are [tex]\(0 \leq y \leq 1\)[/tex].
Now, set up the integrals:
[tex]\[\bar{x} = \frac{\int_{0}^{1} x \cdot x^9 \, dx}{\int_{0}^{1} x^9 \, dx}\][/tex]
[tex]\[\bar{y} = \dfrac{\int_{0}^{1} y \cdot y^9 \, dy}{\int_{0}^{1} y^9 \, dy}\][/tex]
1. [tex]\(\int_{0}^{1} x \cdot x^9 \, dx\):[/tex]
[tex]\[\int_{0}^{1} x \cdot x^9 \, dx = \int_{0}^{1} x^{10} \, dx[/tex]
[tex]= \left[\dfrac{x^{11}}{11}\right]_{0}^{1} = \dfrac{1}{11}\][/tex]
2. [tex]\(\int_{0}^{1} x^9 \, dx\):[/tex]
[tex]\[\int_{0}^{1} x^9 \, dx = \left[\dfrac{x^{10}}{10}\right]_{0}^{1}[/tex]
[tex]= \dfrac{1}{10}\][/tex]
3.[tex]\(\int_{0}^{1} y \cdot y^9 \, dy\):[/tex]
[tex]\[\int_{0}^{1} y \cdot y^9 \, dy = \int_{0}^{1} y^{10} \,[/tex] dy
[tex]= \left[\dfrac{y^{11}}{11}\right]_{0}^{1} = \dfrac{1}{11}\][/tex]
4. [tex]\(\int_{0}^{1} y^9 \, dy\):[/tex]
[tex]\[\int_{0}^{1} y^9 \, dy = \left[\frac{y^{10}}{10}\right]_{0}^{1}[/tex]
[tex]= \dfrac{1}{10}\][/tex]
Now, the centroid coordinates:
[tex]\[\bar{x} = \dfrac{\frac{1}{11}}{\dfrac{1}{10}} = \dfrac{10}{11}\][/tex]
[tex]\[\bar{y} = \dfrac{\frac{1}{11}}{\dfrac{1}{10}} = \dfrac{10}{11}\][/tex]
So, the centroid of the region is [tex]\(\left(\dfrac{10}{11}, \dfrac{10}{11}\right)\)[/tex].

Marcel is performing the first test on his company's new electric car. During the test, the electric car reaches a maximum speed of 81 mph.
The performance test results of the electric car can be modeled by the following graph, where x represents time, in seconds at the start of the test, and y represents the speed, in miles per hour.
At 0 seconds and 12 seconds, the electric vehicle is not moving.
What is speed?The most crucial scientific notion is measurement.
Base or physical fundamental units are used to quantify a wide range of quantifiable quantities.
One such measurable metric is speed, which calculates the ratio between the distance an object travels and the time needed to cover that distance.
The distance traveled in relation to the time it took to travel that distance is how speed is defined.
Since speed simply has a direction and no magnitude, it is a scalar quantity.
When an object travels the same distance in the same amount of time, it is said to be moving at a uniform speed.
Average speed is the constant speed determined by the ratio of the total distance traveled by an object to the total amount of time it took to travel that distance.
According to our question-
At the start of the test, x: represents the time in seconds.
Y: stands for the speed, expressed in miles per hour.
Then, we have this:
x = 0 —-> y = 0
x = 12 —-> y = 0
