A solid is made by a hemisphere and cylinder having equal radii. The volume of the solid is 2707 cm'. If the height of the cylinder is 80 cm, find the total surface area of the solid​

Answers

Answer 1

The total surface area of the solid is approximately 1818 [tex]cm^{2}[/tex]. Let's call the radius of the hemisphere and cylinder "r".

The volume of the solid is the sum of the volumes of the hemisphere and cylinder: V = (2/3)π[tex]r^{3}[/tex] + π[tex]r^{2}[/tex]h. Substituting in the given values, we get: 2707 = (2/3)π [tex]r^{3}[/tex] + π[tex]r^{2}[/tex](80)

To solve for r, we can rearrange the equation and use a numerical method or calculator. We get: r ≈ 11.6 cm

Now, we can use the radius to find the surface area of the solid. The surface area is the sum of the curved surface areas of the hemisphere and cylinder, plus the area of the circular base of the cylinder: A = 2π[tex]r^{2}[/tex] + 2πrh + π[tex]r^{2}[/tex].

Substituting in the given values and solving for A, we get: A ≈ 1818 [tex]cm^{2}[/tex]. Therefore, the total surface area of the solid is approximately 1818 [tex]cm^{2}[/tex].

Answers

The equation of the line in point-slope form is y - 2 = -3(x + 9), and in slope-intercept form is y = -3x - 25.

To find the equation of the line passing through(- 9,2) and parallel to the line y =  – 3x 3, we need to use the fact that  resemblant lines have the same  pitch.  

The  pitch of the given line y =  – 3x 3 is-3,

so the  pitch of the  resemblant line we want to find is also-3.   Point-  pitch form  Using the point-  pitch form, the equation of the line is given by

 y- y1 =  m( x- x1),

where( x1, y1) is the given point and

m is the  pitch.  

Substituting the given values,

we get   y- 2 = -3( x-(- 9))

Find the equation of a line that goes throught point -2,-5 and is parallel to y = x + 2

Answers

The equation of the line that goes through the point (-2, -5) and is parallel to y = x + 2 is y = x - 3.

To find the equation of a line that goes through the point (-2, -5) and is parallel to y = x + 2, we will follow these steps:

1. Identify the slope of the given line.
2. Use the slope and the given point to find the equation of the new line.

Step 1: Identify the slope of the given line.
The equation of the given line is y = x + 2. This is in slope-intercept form (y = mx + b), where m is the slope and b is the y-intercept. In this case, the slope (m) is 1, as it is the coefficient of x.

Step 2: Use the slope and the given point to find the equation of the new line.
Since the new line is parallel to the given line, it will have the same slope. Therefore, the slope of the new line is also 1.

Now, we will use the point-slope form of a linear equation, which is given by y - y1 = m(x - x1), where m is the slope, and (x1, y1) is the given point.

Plugging in the values, we have:
y - (-5) = 1(x - (-2))
y + 5 = 1(x + 2)

Now, let's rewrite the equation in slope-intercept form:
y + 5 = x + 2
y = x + 2 - 5
y = x - 3

So, the equation of the line that goes through the point (-2, -5) and is parallel to y = x + 2 is y = x - 3.

We can simplify the expression inside the parentheses first, using the rule that says when you raise a power to another power, you multiply the exponents:

$\left(\dfrac{4^{3}}{5^{-2}}\right)^{5} = \left(4^{3} \cdot 5^{2}\right)^{5}$

Now, we can use the rule that says when you raise a product to a power, you raise each factor to the power:

$\left(4^{3} \cdot 5^{2}\right)^{5} = 4^{3 \cdot 5} \cdot 5^{2 \cdot 5}$

Simplifying further:

$4^{3 \cdot 5} \cdot 5^{2 \cdot 5} = 4^{15} \cdot 5^{10}$

we can substitute this expression back into the original expression:

$\left(\dfrac{4^{3}}{5^{-2}}\right)^{5} = \left(4^{3} \cdot 5^{2}\right)^{5}$

To simplify this expression further, we can use the rule that says when you raise a product to a power, you raise each factor to the power:

The longer leg of each right triangle will be twice as long as the shorter leg, and the hypotenuse of each triangle will be 6 inches long. To the nearest tenth of an inch, what will be the length of the shorter leg of each triangle?

Answers

To the nearest tenth of an inch, the length of the shorter leg of each right triangle will be 2.7 inches.

What is the triangle?

A triangle is a polygon with three sides and three angles. The sum of the three angles in a triangle always adds up to 180 degrees. There are many different types of triangles, including equilateral triangles (where all three sides are equal in length and all three angles are 60 degrees), isosceles triangles (where two sides are equal in length and two angles are equal in measure), and scalene triangles (where no sides are equal in length and no angles are equal in measure).

According to the given information

Let x be the length of the shorter leg of each right triangle. Then, the longer leg will be twice as long, so its length will be 2x. Using the Pythagorean theorem, we can write:

x² + (2x)² = 6²

Simplifying and solving for x, we get:

x² + 4x² = 36

5x² = 36

x² = 7.2

x ≈ 2.7

Therefore, to the nearest tenth of an inch, the length of the shorter leg of each right triangle will be 2.7 inches.

Answers

If Juan does not read any books before day 4 and he starts reading at the same rate as Patti for the rest of the month, he would have read 6 books by day 12. The correct option is A.

If Juan does not read any books before day 4, it means he has missed out on the opportunity to read for the first three days. Assuming Patti and Juan have been reading at the same rate since day 4, we can calculate the total number of books they would have read by day 12.

Patti reads one book per day, so by day 12, she would have read a total of 9 books (from day 4 to day 12). If Juan starts reading at the same rate as Patti from day 4, he would also have read 9 books by day 12.

However, we have to account for the fact that Juan did not read any books before day 4. This means that he missed out on the opportunity to read 3 books (one book per day for the first three days). Therefore, by day 12, Juan would have read a total of 6 books (3 books missed + 3 books read from day 4 to day 12).

Therefore, the answer is A. Juan would have read 5 books less than Patti by day 12, since Patti would have read a total of 9 books and Juan would have only read 6.

The equation of the line of best fit for the exam grade per hour studied is


y = 6x + 60. What is the residual for 1 hours of studying?

Answers

The predicted exam grade for 1 hour of studying is 66. Therefore the residual for 1 hours of studying can be calculated as Residual = Actual Exam Grade - 66.

To find the residual for 1 hour of studying, we first need to determine the predicted exam grade and compare it to the actual exam grade for that specific data point.

Using the line of best fit equation y = 6x + 60, we can find the predicted exam grade for 1 hour of studying:

y = 6(1) + 60
y = 6 + 60
y = 66

So, the predicted exam grade for 1 hour of studying is 66. To calculate the residual, you need the actual exam grade for 1 hour of studying.

Answers

So, the answer is:
(a) f(x) does not exist at xa = 16.
(b) lim f(x) as x approaches 16 does not exist.
(c) None of the conditions for continuity are met at xa = 16.

To find the value of xa where the function is discontinuous, we need to look for any points where the function is undefined or where the left and right limits of the function are not equal.
(a) From the given information, we know that the function is undefined at xa = 16. So, this is the point of discontinuity.
(b) To find the left and right limits at xa = 16, we need to approach the point from both sides of the function. So,
lim f(x) as x approaches 16 from the left (denoted as lim-) = Im = 0
lim f(x) as x approaches 16 from the right (denoted as lim+) = Im = 16
Since the left and right limits are not equal, the limit as x approaches 16 does not exist. So,
lim f(x) as x approaches 16 (denoted as lim) does not exist.
(c) To determine which conditions for continuity are not met, we need to check if the function satisfies the three conditions for continuity at xa = 16.
i) The function must be defined at xa = 16. Since the function is undefined at xa = 16, this condition is not met.
ii) The left and right limits of the function must exist and be equal at xa = 16. Since the left and right limits are not equal, this condition is not met.
iii) The value of the function at xa = 16 must be equal to the limit of the function at xa = 16. Since the limit does not exist, this condition is also not met.
Therefore, none of the conditions for continuity are met at xa = 16.
So, the answer is:
(a) f(x) does not exist at xa = 16.
(b) lim f(x) as x approaches 16 does not exist.
(c) None of the conditions for continuity are met at xa = 16.
Note: The terms "discontinuous" and "continuity" are used throughout the explanation to describe the concept and the point of interest. The term "function" refers to the given function that we are analyzing.

b) The associated homogeneous equation are y1(x) = c1e^(-4x) and y2(x) = c2e^(-7x).

c) The form of the particular solution is y_p(x) = Ae^(5x) + Bx + C.

d) By solving the system of equations, it gives A = 1/28, B = 1/28, and C = -211/196.

e) The general solution is y(x) = c1e^(-4x) + c2e^(-7x) + (1/28)e^(5x) + (1/28)x - 211/196.

a) The characteristic equation of the associated homogeneous equation is r^2 + 11r + 28 = 0.

b) Factoring the characteristic equation gives (r + 4)(r + 7) = 0, so the solutions to the associated homogeneous equation are y1(x) = c1e^(-4x) and y2(x) = c2e^(-7x).

c) The form of the particular solution is y_p(x) = Ae^(5x) + Bx + C. Taking the first and second derivatives of y_p(x) gives y_p'(x) = 5A + B and y_p''(x) = 0.

d) Substituting y_p(x), y_p'(x), and y_p''(x) into the original nonhomogeneous equation gives:

0 + 11(5A + B) + 28(Ae^(5x) + Bx + C) = e^(5x) + x + 4

Simplifying this equation gives:

(28A)e^(5x) + (28B)x + 11(5A) + 11B + 28C = e^(5x) + x + 4

Comparing coefficients gives the system of equations:

28A = 1

28B = 1

11(5A) + 11B + 28C = 4

Solving this system of equations gives A = 1/28, B = 1/28, and C = -211/196.

e) The general solution to the nonhomogeneous equation is y(x) = y_h(x) + y_p(x), where y_h(x) = c1e^(-4x) + c2e^(-7x) and y_p(x) = (1/28)e^(5x) + (1/28)x - 211/196. Therefore, the general solution is:

Maddy is an event coordinator who helps

raise money for a children's hospital. At

last year's event, she sold 1200 tickets at

$8 each.


Part A: This year Maddy will reduce ticket

prices by 25%. What will be the price of a

new ticket? Explain your reasoning.

D

Part B: Based on the new price, how many

more tickets will Maddy need to sell to

raise the same amount of money as last

year? Explain your reasoning.

Answers

The price of a new ticket after reducing the ticket price by 25% is $6. Maddy will need to sell 400 more tickets this year to raise the same amount of money as last year.

Number of tickets sold = 1200

Cost of each ticket = $8

Part A:

If Maddy lowers ticket costs by 25%, The price of a new ticket will be:

Ticket price = $8 - (25% of $8)

Ticket price = $6

The New ticket price will be calculated by multiplying 0.75 for reducing the 25% tickets

New ticket price = $8 x 0.75 = $6

Part B:

To find how many tickets Maddy requires to sell to equal the same amount of money collected in the previous year:

Total revenue = total number of tickets x Ticket price

1200 tickets x $8 per ticket = $9,600

= $9,600 / $6

= 1,600

Total tickets need to sell = 1600-1200 = 400

Therefore we can conclude that Maddy will need to sell 400 more tickets this year.

Find the critical point and determine if the function is increasing or decreasing on the given intervals. y = x2 - 4x?, x>0 (Use decimal notation. Give your answer to three decimal places.) critical point c= _____

Answers

The critical point is c = 2, the function is decreasing on the interval 0 < x < 2, and increasing on the interval x > 2.

To find the critical point of the function y = x^2 - 4x, we first need to find its derivative, which represents the slope of the tangent line at any point on the curve.

The derivative of y with respect to x is:

y' = 2x - 4

Now, we need to find the critical points, which occur where the derivative is zero or undefined. In this case, the derivative is a polynomial, so it is never undefined. To find where it equals zero, we set y' equal to zero:

0 = 2x - 4

Solving for x, we get:

x = 4/2 = 2

So, the critical point is c = 2.

Now, we need to determine if the function is increasing or decreasing on the interval x > 0. To do this, we can analyze the sign of the derivative. If y' > 0, the function is increasing; if y' < 0, the function is decreasing.

For x > 2 (to the right of the critical point), the derivative y' = 2x - 4 is positive (since 2x > 4 when x > 2). Therefore, the function is increasing on the interval x > 2.

For x < 2 (to the left of the critical point), the derivative y' = 2x - 4 is negative (since 2x < 4 when x < 2). Therefore, the function is decreasing on the interval 0 < x < 2.

In summary, the critical point is c = 2, the function is decreasing on the interval 0 < x < 2, and increasing on the interval x > 2.

How many different combo meals are possible?

Select from the drop-down menu to correctly complete the statement.

Customers can create (14, 39, 60, 120) different lunch combo meals.

Answers

Customers can create 90 different lunch combo meals.

To find the number of possible combo meals, you can use the multiplication principle, which states that if there are m ways to do one thing and n ways to do another, then there are m x n ways to do both.

Using this principle, the total number of combinations is:

5 (drinks) x 6 (main dishes) x 3 (desserts) = 90

Therefore, there are 90 different lunch combo meals possible.
Customers can create 90 different lunch combo meals.

To find out, you can use the multiplication principle of counting. There are 5 choices for drinks, 6 choices for main dishes, and 3 choices for desserts. To find the total number of possible combinations, you can multiply the number of choices for each category together:

5 drinks x 6 main dishes x 3 desserts = 90 possible combo meals.

Let g(x.y)= 15x2 +2y2. Compute g(3,3), g(0,-2), and g(a,b). g(3,3)= _____

Answers

The function g(x, y) is defined as 15x^2 + 2y^2. To compute g(3,3), g(0,-2), and g(a,b), we substitute the given values into the function.

To find g(3,3), we substitute x = 3 and y = 3 into the function g(x, y) = 15x^2 + 2y^2:

g(3,3) = 15(3)^2 + 2(3)^2

g(3,3) = 135 + 18

g(3,3) = 153

To find g(0,-2), we substitute x = 0 and y = -2 into the function g(x, y) = 15x^2 + 2y^2:

g(0,-2) = 15(0)^2 + 2(-2)^2

g(0,-2) = 0 + 8

g(0,-2) = 8

To find g(a,b), we substitute x = a and y = b into the function g(x, y) = 15x^2 + 2y^2:

g(a,b) = 15a^2 + 2b^2

Note: The function g(a,b) cannot be simplified further without knowing the values of a and b.

Water flows into an empty reservoir at a rate of 3200+ 5t gal/hour. What is the quantity of water in the reservoir after 11 hours? Answer:_____ gallons.

Answers

To find the quantity of water in the reservoir after 11 hours, we need to integrate the rate of flow with respect to time from 0 to 11. The quantity of water in the reservoir after 11 hours is 38,225 gallons.

∫(3200 + 5t) dt from 0 to 11
= [(3200 * 11) + (5/2 * 11^2)] - [(3200 * 0) + (5/2 * 0^2)]
= 35,200 + 302.5
= 35,502.5 gallons
Therefore, the quantity of water in the reservoir after 11 hours is 35,502.5 gallons.

To find the quantity of water in the reservoir after 11 hours with the rate of 3200 + 5t gal/hour, we need to first find the total amount of water that flows into the reservoir within that time.
Step 1: Identify the given rate of flow: 3200 + 5t gal/hour.
Step 2: Integrate the flow rate function with respect to time (t) to find the total quantity of water. The integral of the function will give us the quantity of water in gallons:
∫(3200 + 5t) dt = 3200t + (5/2)t^2 + C, where C is the constant of integration.
Since the reservoir is initially empty, the constant C will be 0.
Step 3: Substitute t=11 hours into the integrated function to find the total quantity of water:
Q(11) = 3200(11) + (5/2)(11)^2
Q(11) = 35200 + 3025
Step 4: Add the values to find the total quantity of water in gallons:
Q(11) = 38225 gallons
The quantity of water in the reservoir after 11 hours is 38,225 gallons.
