use the general slicing method to find the volume of the following solid. the solid whose base is the triangle with vertices , , and and whose cross sections perpendicular to the base and parallel to the y-axis are semicircles
Answers
The equation for the volume of a cylindrical shell is:
V = πr² * h * w, where r is the radius of the semicircle base, h is the height of the shell, and w is the width of the shell.
Volume Of Semicircular Cross-Section SolidThe volume of the solid can be found using the method of cylindrical shells. The volume of each cylindrical shell is equal to the product of the area of the base (a semicircle), the height of the shell, and the width of the shell (which is equal to the difference in the x-coordinates of the two vertices that define the height).
To find the total volume, we would sum up the volumes of all the cylindrical shells, from the top to the bottom of the solid.
The equation for the volume of a cylindrical shell is:
V = πr² * h * w, where r is the radius of the semicircle base, h is the height of the shell, and w is the width of the shell.
The height of the shell is given by the difference in the y-coordinates of the two points that define the height, and the width of the shell is given by the difference in the x-coordinates of these two points.

1.1. How many m³ = are there in 3( mile )³
1.2. How many gal/min correspond to 5ft³ /s. 1.3. Convert the following: 9.50 cm to nm/sec² (5)
Answers
Using the conversion factors, we find that 3 cubic miles is approximately equal to 1.2504543 × 10^10 cubic meters. 5 cubic feet per second is equal to 2244.156 gallons per minute. 9.50 centimeters is equal to 9.50 * 10^7 nanometers per second squared.
1.1. One mile is equal to 1609.34 meters. Since we're dealing with cubic units, we cube the conversion factor.
1 mile = 1609.34 meters
1 mile³ = (1609.34 meters)³ = 4.168181 × 10^9 cubic meters
Therefore, 3 cubic miles is equal to 3 * 4.168181 × 10^9 cubic meters, which is approximately 1.2504543 × 10^10 cubic meters.
1.2. To convert from cubic feet per second (ft³/s) to gallons per minute (gal/min), we use the appropriate conversion factors.
Here are the conversion factors:
1 cubic foot = 7.48052 gallons
1 minute = 60 seconds
So, we set up the conversion as follows:
5 ft³/s * 7.48052 gal/ft³ * 60 s/min = 2244.156 gal/min
Therefore, 5 cubic feet per second is equal to 2244.156 gallons per minute.
1.3. To convert centimeters (cm) to nanometers per second squared (nm/sec²), we use the appropriate conversion factors. Here are the conversion factors:
1 centimeter = 10^7 nanometers
1 second = 1 second
So, we set up the conversion as follows:
9.50 cm * (10^7 nm/cm) / (1 sec)² = 9.50 * 10^7 nm/sec²
Therefore, 9.50 centimeters is equal to 9.50 * 10^7 nanometers per second squared.

Tamara is a chef at a restaurant. She buys rice in bags
that weigh 20 pounds.
Each night, Tamara uses 0,4 pounds of rice. She needs to
order another bag when there are 1.6 pounds of rice left
in her bag.
Question: On Day 1 there are 20 pounds
of rice in her bag. On what day will
Tamara need to order a new bag of rice?
Answers
Using a linear function, it is found that Tamara will need to order a new bag after 46 days.
What is a linear function?A linear function is modeled according to the following rule:
y = mx + b
In which:
m is the slope, which is the rate of change of the function, that is, the change in y divided by the change in x.b is the y-intercept, which is the the value of y when the function crosses the x-axis(x = 0).The slope and the intercept in the context of this problem are given as follows:
Slope of -0.4, as she uses 0.4 pounds a day.Intercept of 20, as the bag initially has 20 pounds.Hence the weight of the bag after d days is given by:
W(d) = 20 - 0.4d.
He needs to order a new bag when W(d) = 1.6, hence:
1.6 = 20 - 0.4d.
0.4d = 18.4
d = 18.4/0.4
d = 46 days.
Hence she needs to order the new bag in 46 days.

How you used the limit definition of a derivative to calculate the instantaneous acceleration. use your results to explain why the limit definition of a derivative is tru
Answers
The instantaneous acceleration at any time t is given by 10t. The limit definition of a derivative is true because it allows us to find the instantaneous rate of change of a function at a specific point.
To use the limit definition of a derivative to calculate instantaneous acceleration, we need to find the derivative of the velocity function with respect to time. The derivative of velocity gives us acceleration.
The limit definition of a derivative is given by:
f'(x) = lim (h→0) [f(x+h) - f(x)] / h
To calculate instantaneous acceleration, we substitute the velocity function, v(t), into the limit definition. Let's say v(t) = 5t^2.
Using the limit definition, we have:
a(t) = lim (h→0) [v(t+h) - v(t)] / h
Substituting v(t) = 5t^2, we get:
a(t) = lim (h→0) [5(t+h)^2 - 5t^2] / h
Expanding and simplifying:
a(t) = lim (h→0) [10th + 5h^2] / h
Now, we can cancel out the h term:
a(t) = lim (h→0) 10t + 5h
Taking the limit as h approaches 0, we get:
a(t) = 10t
Therefore, the instantaneous acceleration at any time t is given by 10t.
The limit definition of a derivative is true because it allows us to find the instantaneous rate of change of a function at a specific point. By taking the limit as the change in input approaches zero, we are able to approximate the exact rate of change at that point. This concept is fundamental to calculus and is used in various applications such as physics, engineering, and economics.

Given j(-8,-5) and l(6,-11) if k(r-4,2s) is the midpoint of jl which correctly gives the values of r and s?
Answers
The values of r and s is -1 and -4 respectively.
Given that:-
coordinates of j are (-8,-5)
coordinates of l are (6,-11)
coordinates of k are (r-4,2s)
Also, k is the mid-point of jl.
We have to find the values of r and s.
We know that, for (x,y) and (z,w), the mid-point is ((x+z)/2, (y+w)/2).
Here,
(x,y) = (-8.-5)
(z,w) = (6,-11)
(r-4,2s) = ((x+z)/2,(y+w)/2)
Hence,
(r-4,2s) = ((-8+6)/2,(-5-11)/2)
(r-4,2s) = (-1,-8)

18.Lupe and her friends spent $20 on snack mix and water. They bought x bags of snack mix and y bottles of water. They bought a total of 11 items. The system of equations can be used to determine how many of each item they bought.
Answers
Answer:
bags of snack = x = 6
bottles of water = y = 5
Step-by-step explanation:
The system of equations can be used to determine how many of each item they bought.
20.00=2.50x+1.00y
11=x+y
how many bags of snack mix did they buy?
Let
bags of snack = x
bottles of water = y
20.00 = 2.50x + 1.00y (1)
11 = x + y (2)
From (2)
x = 11 - y
Substitute x = 11 - y into (1)
20.00 = 2.50x + 1.00y
20.00 = 2.50(11 - y) + 1.00y
20.00 = 27.5 - 2.50y + 1.00y
20.00 - 27.5 = -2.50y + 1.00y
-7.5 = -1.5y
y = -7.5/-1.5
y = 5
Substitute y = 5 into (2)
11 = x + y
11 = x + 5
11 - 5 = x
x = 6
bags of snack = x = 6
bottles of water = y = 5

A random sample of 140 college graduates with Bachelor degrees found that 75 were women. The National Center for Education Statistics would like to set α = 0.10. The conclusion for this hypothesis test would be that because the absolute value of the test statistic is __________________________________.
Answers
This question involves the hypothesis test for the proportion. First we build the hypothesis, then find the test statistic, and according to the test statistic, we get the following answer:
The conclusion for this hypothesis test would be that because the absolute value of the test statistic is less than the critical value of 1.645, we do not reject the null hypothesis that the proportion of Bachelor's degrees that were earned by women equals 0.60.
-------------------------------------------------------------------
The National Center for Education Statistics would like to test the hypothesis that the proportion of Bachelor's degrees that were earned by women equals 0.60
This means that at the null hypothesis, it is tested if the proportion is of 0.6, that is:
\(H_0: p = 0.6\)
At the alternative hypothesis, we test if the proportion is different of 0.6, that is:
\(H_1: p \neq 0.6\)
-------------------------------------------------------------------
Decision rule:
Two-tailed test(test if the proportion is different of a value), so we exclude the top and bottom 0.1/2 = 0.05, meaning that looking at the z-table, we find a critical value of \(|Z_c| = 1.645\), and the decision rule is:
Accept the null hypothesis: \(|Z| < 1.645\)
Reject the null hypothesis: \(|Z| > 1.645\)
-------------------------------------------------------------------
Test statistic:
\(z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}\)
In which X is the sample mean, \(\mu\) is the value tested at the null hypothesis, \(\sigma\) is the standard deviation and n is the size of the sample.
0.6 is tested at the null hypothesis:
This means that \(\mu = 0.6, \sigma = 0.4\)
75 out of a sample of 140:
This means that:
\(n = 140, \pi = \frac{75}{140} = 0.5357\)
-------------------------------------------------------------------
Value of the test statistic:
\(z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}\)
\(z = \frac{0.5357 - 0.6}{\frac{\sqrt{0.6*0.4}}{\sqrt{140}}}\)
\(z = -1.55\)
So |z| = 1.55
-------------------------------------------------------------------
Decision:
The conclusion for this hypothesis test would be that because the absolute value of the test statistic is less than the critical value of 1.645, we do not reject the null hypothesis that the proportion of Bachelor's degrees that were earned by women equals 0.60.
