what is the volume of the solid generated when the region in the first quadrant bounded by the graph of y=√(100−4x^2) and the x- and y-axes is revolved about the y-axis?
The volume of the solid generated when the region in the first quadrant, bounded by the graph of y = √(100 - 4x^2) and the x- and y-axes, is revolved about the y-axis is 25π/8 cubic units.
The volume of the solid generated when the region in the first quadrant, bounded by the graph of y = √(100 - 4x^2) and the x- and y-axes, is revolved about the y-axis is ___ cubic units.
To find the volume of the solid, we can use the method of cylindrical shells. The volume of a cylindrical shell is given by the formula:
V = 2π ∫[a,b] x f(x) dx
In this case, the region is bounded by the graph of y = √(100 - 4x^2) and the x- and y-axes. To determine the limits of integration, we need to find the x-values where the curve intersects the x-axis. The curve intersects the x-axis when y = 0, so we solve the equation √(100 - 4x^2) = 0:
100 - 4x^2 = 0
4x^2 = 100
x^2 = 25
x = ±5
Since we are considering the region in the first quadrant, the limit of integration is from 0 to 5.
Now, let's calculate the volume using the given formula:
V = 2π ∫[0,5] x √(100 - 4x^2) dx
To simplify the integral, we can make a substitution. Let u = 100 - 4x^2, then du = -8x dx. Rearranging, we have x dx = -(1/8) du.
Substituting the limits of integration and the expression for x dx, we get:
V = 2π ∫[0,5] -(1/8)u du
V = -(π/4) ∫[0,5] u du
V = -(π/4) [(u^2)/2] evaluated from 0 to 5
V = -(π/4) [(25/2) - (0/2)]
V = -(π/4) (25/2)
V = -25π/8
Since the volume cannot be negative, we take the absolute value:
V = 25π/8
Therefore, the volume of the solid generated when the region in the first quadrant, bounded by the graph of y = √(100 - 4x^2) and the x- and y-axes, is revolved about the y-axis is 25π/8 cubic units.

In a school thereare 160 boys to number of girls is 2:3how many girls there are
Answer:
240 girls
Step-by-step explanation:
Let number of girls be x.
160:x = 2:3
Multiply right side by 80--> 160:x = 160:240
x=240.
So there are 240 girls.
Answer:
There should be 240 girls.
Step-by-step explanation:
Ultimately, you want 40% of the school to be boys and 60% of the school to be girls which equal to the ratio 2:3. Divide 160 by 2 to get 80 for the first part of the ratio, then you should multiply that number by 3 to get 240 as the number of girls in that school.
The ratio should be 160:240 when you put the number of boys and girls in this situation.

a water wave travels a distance of 10.0 meters in 5.0 seconds. what can be determined from this information?
The speed of the water wave is 2.0 meters per second.
The speed of a wave is calculated by dividing the distance traveled by the time it takes to travel that distance. In this case, the distance traveled by the water wave is 10.0 meters, and the time taken is 5.0 seconds.
To determine the speed, we use the formula:
Speed = Distance / Time
Substituting the given values, we have:
Speed = 10.0 meters / 5.0 seconds = 2.0 meters per second
Therefore, from the given information, we can determine that the speed of the water wave is 2.0 meters per second.
This information about the speed of the water wave is useful for various purposes. It allows us to understand how quickly the wave is propagating through the medium. It also helps in analyzing wave behavior, such as interference, reflection, or refraction, and studying the characteristics of the medium through which the wave is traveling. Additionally, the speed of the wave can be used in calculations involving wave frequencies, wavelengths, and periods.

Answer the problem below
Find the product of 32 and 46. Now reverse the digits and find the product of 23 and 64. The products are the same!
Does this happen with any pair of two-digit numbers? Find two other pairs of two-digit numbers that have this property.
Is there a way to tell (without doing the arithmetic) if a given pair of two-digit numbers will have this property?
Let's calculate the products and check if they indeed have the same value:
Product of 32 and 46:
32 * 46 = 1,472
Reverse the digits of 23 and 64:
23 * 64 = 1,472
As you mentioned, the products are the same. This phenomenon is not unique to this particular pair of numbers. In fact, it occurs with any pair of two-digit numbers whose digits, when reversed, are the same as the product of the original numbers.
To find two other pairs of two-digit numbers that have this property, we can explore a few examples:
Product of 13 and 62:
13 * 62 = 806
Reversed digits: 31 * 26 = 806
Product of 17 and 83:
17 * 83 = 1,411
Reversed digits: 71 * 38 = 1,411
As for determining if a given pair of two-digit numbers will have this property without actually performing the multiplication, there is a simple rule. For any pair of two-digit numbers (AB and CD), if the sum of A and D equals the sum of B and C, then the products of the original and reversed digits will be the same.
For example, let's consider the pair 25 and 79:
A = 2, B = 5, C = 7, D = 9
The sum of A and D is 2 + 9 = 11, and the sum of B and C is 5 + 7 = 12. Since the sums are not equal (11 ≠ 12), we can determine that the products of the original and reversed digits will not be the same for this pair.
Therefore, by checking the sums of the digits in the two-digit numbers, we can determine whether they will have the property of the products being the same when digits are reversed.
At a football game, a vender sold a combined total of 181 sodas and hot dogs. The number of hot dogs sold was 51 less than the number of sodas sold. Find the
number of sodas sold and the number of hot dogs sold.
Answer: Number of hot dogs sold = 65
number of soda sold = 116.
Step-by-step explanation:
Let the number of hot dogs sold be represented by x.
Since the number of hot dogs sold was 51 less than the number of sodas sold, then the number of soda sold will be: = x + 51
Since the addition of both hot dogs and soda equals 181, we can form this into an equation which will be:
= x + (x + 51) = 181
x + x + 51 = 181
2x + 51 = 181
2x = 181 - 51
2x = 130
x = 130/2
x = 65
Number of hot dogs sold = 65
Since number of soda sold equals:
= x + 51
= 65 + 51
= 116
Therefore, number of soda sold is 116.

Martin is organising a summer fair.
He needs bread buns and burgers for the barbecue.
Bread buns are sold in packs. Each pack contains 40 bread buns.
Burgers are sold in packs. Each pack contains 24 burgers.
Martin buys exactly the same number of bread buns as burgers.
What is the least number of each pack that Martin buys?
The least number of each pack that Martin can buy is 5 packs of burger and 3 packs of bread buns.
Since the packs of bread buns contain 40 bread buns and each pack of burgers contains 24 burgers, then we'll calculate the multiples of each number. This will be:
Multiples of 24 = 24, 48, 72, 96, 120
Multiples of 40 = 40, 80, 120, ...
Therefore, the least common multiple is 120.
The least number of packs of burger to buy is 5 and least number of packs of bread buns to buy is 3.

(c) Sketch an arrow in each open region divided by the nullclines that suggests the direction in which a solution point is moving when it is in that region.
The equilibrium points are y = 2 , x = -1 , 2
Equilibrium is a state in which opposing forces or influences are balanced. It is a state of rest or balance resulting from the equal action of opposing forces. In economics, equilibrium is a situation in which the forces of supply and demand in a market are balanced and there is no tendency for the price to either rise or fall.
The given system is
x' = y − 2
y' = (x+1)(x-2)
a) The equilibrium points are given by
f(x) = 0 and g(x) = 0
y - 2 = 0 and (x + 1)(x - 2) = 0
y = 2 and x = -1 , 2
So the equilibrium points are (-1,2) and (2,2)
The x null clines are given by x' = 0
y - 2 = 0
y = 2
The y null clines are given by y' = 0
(x + 1)(x - 2) = 0

the statue of liberty in new york city is approximately 305 ft tall. how many u.s. half dollars would be in a stack of the same height? each half dollar is 2.15 mm thick.
There would be approximately 43,149 U.S. half dollars in a stack that is the same height as the Statue of Liberty.
To determine the number of U.S. half dollars that would be in a stack the same height as the Statue of Liberty, we need to convert the height of the statue from feet to millimeters and then divide it by the thickness of a single half dollar.
First, let's convert the height of the Statue of Liberty from feet to millimeters. We know that 1 foot is equal to 304.8 millimeters (rounded to the nearest tenth). Therefore, the height of the Statue of Liberty in millimeters is:
305 ft * 304.8 mm/ft = 92918 mm (rounded to the nearest whole number)
Next, we need to determine the thickness of a U.S. half dollar. Given that each half dollar is 2.15 mm thick, we can now calculate the number of half dollars in a stack that is the same height as the Statue of Liberty:
Number of half dollars = Height of stack / Thickness of a half dollar
Number of half dollars = 92918 mm / 2.15 mm
Number of half dollars ≈ 43149 (rounded to the nearest whole number)
Therefore, there would be approximately 43,149 U.S. half dollars in a stack that is the same height as the Statue of Liberty.

suppose a fair die is rolled 11 times. (a) what is the probability p that a 3 will occur any given time the die is rolled? (enter your probability as a fraction.)
The probability that a 3 will get any given times the dies is rolled is 0.17x
Total number of outcomes in one roll = 6
The favorable outcome = 3
The probability = Number of favorable outcomes / Total number of outcomes
Substitute the values in the equation
The probability of getting 3 in first roll= 1 / 6
Total number of times the die rolled = 11 times
The probability of getting 3 in all given times = (The probability of getting 3 in first roll )^ (Number of times the die rolled)
Consider the number of rolls as x
Substitute the values in the equation
The probability of getting 3 in all the given times = (1/6)^x
