Answer:
We can use the principle of conservation of momentum to solve this problem. According to this principle, the total momentum of a system of objects remains constant if there are no external forces acting on the system.
Initially, only the cue ball is moving, and the 8 ball is at rest. Therefore, the initial momentum of the system is:
p_initial = m1 * v1 + m2 * v2
= 0.2 kg * 10 m/s + 0.15 kg * 0 m/s
= 2 kg m/s
After the collision, the cue ball is rolling forward at 1 m/s, and the 8 ball is moving in some direction with some velocity v_final. Therefore, the final momentum of the system is:
p_final = m1 * v1 + m2 * v_final
According to the conservation of momentum principle, p_initial = p_final. Therefore,
2 kg m/s = 0.2 kg * 1 m/s + 0.15 kg * v_final
Solving for v_final, we get:
v_final = (2 kg m/s - 0.02 kg m/s) / 0.15 kg
= 13.33 m/s
Therefore, the velocity of the 8 ball after the collision is 13.33 m/s.

The volume of the cylinder is approximately 753.98 cubic centimeters.and the volume of the cone is approximately 600.98 cubic centimeters.
The solutions of the question are given as following :-
1.To find the radius of a cone with height 19 cm and width (diameter) 12 cm, we can use the Pythagorean theorem to relate the height, radius, and slant height of the cone. The slant height is the distance from the vertex of the cone to any point on the circular base, and it is related to the height and radius by the equation:
slant height² = height² + radius²
We know the height is 19 cm, and the diameter (width) is 12 cm, so the radius is half of the diameter, or 6 cm. We can now substitute these values into the equation for the slant height:
slant height²= 19²+ 6²
slant height² = 361 + 36
slant height² = 397
slant height ≈ 19.92 cm
Therefore, the radius of the cone is approximately:
radius = √(slant height² - height²)
radius = √(397 - 19²)
radius ≈ 5.65 cm (rounded to two decimal places)
2.Volume = (1/3) * π * radius²* height
Substituting the given values, we get:
Volume = (1/3) * π * (5.65 cm)²* 19 cm
Volume ≈ 600.98 cubic centimeters
Therefore, the volume of the cone is approximately 600.98 cubic centimeters.
3.To find the volume of the cylinder with height 15 cm and radius (width/2) 4 cm, we can use the formula for the volume of a cylinder:
Volume = π * radius² * height
Substituting the given values, we get:
Volume = π * (4 cm)² * 15 cm
Volume = π * 16 cm² * 15 cm
Volume ≈ 753.98 cubic centimeters
Therefore, the volume of the cylinder is approximately 753.98 cubic centimeters.

The constant of proportionality (r) in the table of values of x and y has a value of 0.5.
Calculating the constant of proportionalityTo find the constant of proportionality (r) in the equation y = rx, we need to determine the ratio of y to x for each pair of quantities given in the table.
If x and y are proportional, then this ratio should be the same for all pairs of quantities.
Using the table, we have:
y/x = 4.5/9 = 0.5
y/x = 7/14 = 0.5
y/x = 15/30 = 0.5
Since the ratio of y to x is the same for all pairs of quantities, we can conclude that x and y are indeed proportional, and the constant of proportionality (r) is 0.5.
Therefore, the equation that represents the relationship between x and y is:
y = 0.5x

Write the equation of the trigonometric graph. Use a positive coefficient on cosine for this activity.
The cosine function's positive coefficient ensures that the curve moves trigonometry downward from its highest point rather than upward from its lowest point.
what is trigonometry?The area of mathematics called trigonometry examines how triangle side lengths and angles relate to one another. The subject first came to light in the Hellenistic era, roughly in the third century BC, as a result of the use of geometry in astronomical investigations. The area of mathematics known as exact techniques deals with several trigonometric functions and possible computations using them. There are six common trigonometric functions in trigonometry. These go by the designations sine, cosine, tangent, cotangent, secant, and cosecant, respectively (csc). The study of triangle properties, particularly those of right triangles, is known as trigonometry. Consequently, studying geometry entails learning about the characteristics of all geometric shapes.
A trigonometric equation involving a cosine function with a positive coefficient looks like this:
y = 2cos(x) (x)
If this equation were graphed, a cosine curve with a period of 2 would be visible, oscillating between a maximum value of 2 and a minimum value of -2. The cosine function's positive coefficient ensures that the curve moves downward from its highest point rather than upward from its lowest point.

in a certain state, 60% of all adults have high blood pressure, 45% have high cholesterol and 20% have both high blood pressure and high cholesterol. what is the probability that a randomly selected adult from the state has high blood pressure but not high cholesterol?
The probability that a randomly selected adult from the state has high blood pressure but not high cholesterol is 0.40 or 40%.
To find the probability that a randomly selected adult from the state has high blood pressure but not high cholesterol, we need to subtract the probability of having both high blood pressure and high cholesterol from the probability of having high blood pressure.
Using set notation, let A be the event of having high blood pressure and B be the event of having high cholesterol. Then, the probability of having both high blood pressure and high cholesterol can be written as
P(A ∩ B)= 0.20
The probability of having high blood pressure can be written as
P(A) = 0.60
Therefore, the probability of having high blood pressure but not high cholesterol is:
P(A) - P(A ∩ B) = 0.60 - 0.20 = 0.40
Thus, the probability that a randomly selected adult from the state has high blood pressure but not high cholesterol is 0.40 or 40%.

Solve the polynomial
x^3-7x^2-x+7=0
Answer:
x = 1, x = 7, and x = -1.
Step-by-step explanation:
o solve the polynomial equation x^3 - 7x^2 - x + 7 = 0, we can use a combination of synthetic division and factoring by grouping:
First, we need to find a root of the polynomial using the Rational Root Theorem. The possible rational roots of the polynomial are the factors of 7 (the constant term) divided by the factors of 1 (the leading coefficient), or ±1, ±7. By trying each of these values in the polynomial, we find that x = 1 is a root.
Using synthetic division, we can divide the polynomial by (x - 1) to obtain a quadratic equation:
1 | 1 -7 -1 7
| 1 -6 -7
|_____________
1 -6 -7 0
Therefore, (x - 1) is a factor of the polynomial, and we have:
x^3 - 7x^2 - x + 7 = (x - 1)(x^2 - 6x - 7)
Now we need to solve the quadratic equation x^2 - 6x - 7 = 0. We can factor it as (x - 7)(x + 1) = 0, so the solutions are x = 7 and x = -1.
Therefore, the solutions to the original polynomial equation x^3 - 7x^2 - x + 7 = 0 are x = 1, x = 7, and x = -1.

feet tall casts a $3\frac{1}{2}$
-foot-long shadow. A nearby flagpole casts a 28-foot-long shadow. What is the height (in feet) of the flagpole?
The height of the flagpole is [tex]$\frac{28}{3\frac{1}{2}}\times 5\frac{1}{2}=50$[/tex]feet.
[tex]$\frac{28}{3\frac{1}{2}}\times 5\frac{1}{2}$[/tex]
[tex]$\frac{28\times 5\frac{1}{2}}{3\frac{1}{2}}$[/tex]
[tex]$\frac{140+7}{7}$[/tex]
[tex]$\frac{147}{7}$[/tex]
[tex]$50.71\approx50$[/tex] feet
The person and the flagpole are in the same environment, so if the person's height is 5 and a half feet and their shadow is 3 and a half feet, then the flagpole's shadow should be in the same ratio. By calculating the ratio between the flagpole's shadow and the person's height, we can determine the height of the flagpole. The ratio between the flagpole's shadow (28 feet) and the person's height (5 and a half feet) is 28 divided by 3 and a half. Multiplying this ratio by the person's height will give us the flagpole's height. The flagpole's height is approximately fifty feet.

How much would you have to deposit now to be able to withdraw $2,400 at the end of each year for 10 years from an account that earns 4% compounded annually?
Answer:
The amount that would need to be deposited now to withdraw $2,400 at the end of each year for 10 years from an account that earns 4% compounded annually is $60,058.50.
Step-by-step explanation:
To determine how much would need to be deposited now to withdraw $2,400 at the end of each year for 10 years from an account that earns 4% compounded annually, we can use the present value formula for an annuity:
PMT x [(1 - (1 + r/n)^(-nt)) / (r/n)] = PV
Where:
PMT = the periodic payment
r = the annual interest rate (as a decimal)
n = the number of times the interest is compounded per year
t = the total number of years
PV = the present value (the amount to be deposited now)
In this case, we have:
PMT = $2,400
r = 4% = 0.04 (decimal)
n = 1 (compounded annually)
t = 10 years
Plugging these values into the formula, we get:
PV = $2,400 x [(1 - (1 + 0.04/1)^(-1*10)) / (0.04/1)]
PV = $2,400 x [(1 - 0.5537) / 0.04]
PV = $60,058.50
Therefore, the amount that would need to be deposited now to withdraw $2,400 at the end of each year for 10 years from an account that earns 4% compounded annually is $60,058.50.

Write a system of equations for this-
Cora ran 3 miles last week and will run 7 miles per week from now on. Hana ran 9 miles last week and will run 4 miles per week from now on
The solution to the system of equations is C = 3 and H = 9.
Let C = Cora's miles last week and H = Hana's miles last week
The equation for Cora's miles is C + 7x = 3, and the equation for Hana's miles is H + 4x = 9, where x is the number of weeks.
The solution to this system of equations is C = 3, and H = 9. This can be determined by solving each equation separately and then checking that the answers satisfy both equations.
For Cora's equation, subtract 7x from both sides to get C = 3 - 7x. Solving for x gives x = (3 - C) / 7. Plugging this into Hana's equation gives H + 4((3 - C) / 7) = 9. Simplifying this equation gives H = 9 - 12 + 4C.
Checking the answers, C = 3 - 7(0) = 3, and H = 9 - 12 + 4(3) = 9. Both equations are satisfied by C = 3 and H = 9, so this is the solution to the system of equations.

A = L(L - 4) = 32
Expanding the left side of the equation, we get:
L^2 - 4L = 32
Rearranging and factoring, we get:
L^2 - 4L - 32 = 0
We can solve for L by using the quadratic formula:
L = (-b ± sqrt(b^2 - 4ac)) / 2a
Where a = 1, b = -4, and c = -32.
L = (-(-4) ± sqrt((-4)^2 - 4(1)(-32))) / 2(1)
L = (4 ± sqrt(16 + 128)) / 2
L = (4 ± sqrt(144)) / 2
L = (4 ± 12) / 2
L = 8 or L = -4
Since the length must be a positive value, we take L = 8.
Therefore, the length of the rectangle is 8 units.
The width and length of the rectangle will be 4 units and 8 units, respectively.
What is the area of the rectangle?Let W be the rectangle's width and L its length.
The area of the rectangle is the multiplication of the two different sides of the rectangle. Then the rectangle's area will be
Area of the rectangle = L × W square units
The width of a square shape is 4 units less than the length. The region of the square shape is 32 square units. Then the equations are given below.
[tex]W = L - 4[/tex] ...1
[tex]L \times W = 32[/tex] ...2
From equations 1 and 2, then we have
[tex]L \times (L - 4) = 32[/tex]
[tex]L^2 - 4L = 32[/tex]
[tex]L^2 - 4L - 32 = 0[/tex]
[tex]L^2 - 8L + 4L - 32 = 0[/tex]
[tex]L(L - 8) + 4(L - 8) = 0[/tex]
[tex](L - 8)(L + 4) = 0[/tex]
[tex]L = 8, -4[/tex]
Then the width of the rectangle is given as,
[tex]W = 8 - 4[/tex]
[tex]W = 4 \ units[/tex]
The width and length of the rectangular shape will be 4 units and 8 units, separately.
