The answer to this question

The expression that represents the volume of the cylinder is:

V = π[tex]r^{2}[/tex]h

What is cylinder?

A cylinder is a three-dimensional geometric shape that consists of two parallel circular bases of the same size and shape, and a curved lateral surface connecting the bases. The cylinder can be thought of as a tube or a can. The lateral surface of the cylinder is formed by "unrolling" a rectangular shape along the circumference of the base.

There appears to be a typographical error in the given formula for the volume of a cylinder. The correct formula is:

V = π[tex]r^{2}[/tex]h

where V is the volume of the cylinder, r is the radius of the circular base, and h is the height of the cylinder.

Using this formula, the expression that represents the volume of the cylinder is:

V = π[tex]r^{2}[/tex]h

The three numbers are 4, 8, and 14.

Let's use variables to represent the three numbers

Let x be the first number.

Then the second number is twice the first, so it is 2x.

The third number is 6 more than the second, so it is 2x + 6.

We know that the sum of the three numbers is 26, so we can write an equation:

x + 2x + (2x + 6) = 26

Now we can solve for x

5x + 6 = 26

5x = 20

x = 4

So the first number is 4.

To find the second number, we can use the equation we wrote earlier:

2x = 2(4) = 8

So the second number is 8.

To find the third number, we can use the other equation we wrote earlier

2x + 6 = 2(4) + 6 = 14

So the third number is 14.

The probability of a score for a recent basketball game, shenille attempted only three-point shots and two-point shots is 18 points in the game. The answer is Option B.

Let x be the number of three-point shots and y be the number of two-point shots attempted by Shenille.

Then, we have:

x + y = 30 (total number of shots attempted)

Let's solve for one of the variables. For example, we can solve for x by subtracting y from both sides of the equation:

x = 30 - y

Now, we can express Shenille's points in terms of x and y:

Points = 3x + 2y

Substituting x = 30 - y, we get:

Points = 3(30 - y) + 2y

Points = 90 - y

Shenille's success rate for three-point shots is 20%, so the number of successful three-point shots she made is 0.2x. Similarly, the number of successful two-point shots she made is 0.3y.

Total points scored = (0.2x)(3) + (0.3y)(2)

Substituting x = 30 - y, we get:

Total points scored = (0.2(30 - y))(3) + (0.3y)(2

Total points scored = 18 + 0.4y

Now we need to maximize the total points scored by Shenille. Since she attempted 30 shots in total, we have:

y = 30 - x

Substituting this into the equation for total points, we get:

Total points scored = 18 + 0.4(30 - x)

Total points scored = 30 - 0.4x

This is a linear function, which is maximized at its endpoint. The maximum value of this function occurs at x = 0, which means Shenille attempted all two-point shots. In this case, y = 30, and the total points scored would be:

Total points scored = 0 + 0.3(30)(2)

Total points scored = 18

There are 173 kinda-prime positive integer less than 1000.

To find the number of kinda-prime positive integer less than 1000, we'll follow these steps:

1. Understand the definition of a kinda-prime number: A positive integer is kinda-prime if it has a prime number of positive integer divisors.
2. Determine the number of prime numbers less than 1000: There are 168 prime numbers less than 1000, as given.
3. Determine the possible prime number of divisors: Since 168 is not too large, we only need to consider 2 and 3 as possible prime numbers of divisors for a kinda-prime number.
4. Analyze the cases:

Case 1: Kinda-prime numbers with 2 divisors (prime numbers)
All prime numbers have exactly 2 divisors (1 and itself). Thus, all 168 prime numbers less than 1000 are kinda-prime.

Case 2: Kinda-prime numbers with 3 divisors

With 90% confidence, we can estimate that the true population mean lies between 13.96 and 16.04.

If the population appears to be normally distributed, and σ (population standard deviation) is unknown, we can use a t-distribution to calculate the confidence interval.

To find the confidence interval, we need to use the following formula

CI = X' ± t_(α/2, n-1) × (s/√n)

Where X' is the sample mean, t_(α/2, n-1) is the critical t-value based on the desired confidence level (α) and the sample size (n-1), s is the sample standard deviation, and √n is the square root of the sample size.

Given that we have a confidence level of 90%, α = 0.10, and we need to find the critical t-value for a two-tailed test with 10-1=9 degrees of freedom. Using a t-distribution table, we find that the critical t-value is approximately 1.833.

Assuming that we have a sample mean of X' = 15 and a sample standard deviation of s = 2, we can now calculate the confidence interval

CI = 15 ± 1.833 × (2/√10)

CI = 15 ± 1.04

CI = (13.96, 16.04)

Therefore, with 90% confidence, we can estimate that the true population mean lies between 13.96 and 16.04.

The distance from point A to point B is approximately 926.4 feet.

An angle is a measure of the amount of rotation between two lines, rays, or line segments that share a common endpoint, called the vertex. It is typically measured in degrees or radians.

Let's call the distance between point A and the lighthouse "x" and the distance between point B and the lighthouse "y". We want to find the value of "y".

From point A, the crew measures the angle of elevation to the lighthouse to be 6. This means that the angle formed between the horizontal line passing through point A and the line connecting point A to the top of the lighthouse is 6. We can draw a right triangle ABC where point A is the bottom left corner, point B is the bottom right corner, and point C is the top of the lighthouse. The line segment AC represents the height of the lighthouse (111 feet) and the line segment AB represents the distance between point A and the lighthouse (x).

Using trigonometry, we know that:

tan(6) = AC/AB

tan(6) = 111/x

x = 111/tan(6)

Now, from point B, the crew measures the angle of elevation to the lighthouse to be 13. This means that the angle formed between the horizontal line passing through point B and the line connecting point B to the top of the lighthouse is 13. We can draw a right triangle BCD where point B is the bottom left corner, point C is the top of the lighthouse (the same point as in the previous triangle), and point D is the bottom right corner. The line segment CD represents the height of the lighthouse (111 feet) and the line segment BD represents the distance between point B and the lighthouse (y).

Using trigonometry, we know that:

tan(13) = CD/BD

tan(13) = 111/y

y = 111/tan(13)

Therefore, the distance between point A and point B is:

y - x = 111/tan(13) - 111/tan(6)

Using a calculator, we get:

y - x ≈ 926.4 feet

Rounding to the nearest tenth of a foot, the distance from point A to point B is approximately 926.4 feet.

In Mathematics and Geometry, the point-slope form of a straight line can be calculated by using the following mathematical equation (formula):

y - y₁ = m(x - x₁)

Where:

First of all, we would determine the slope of this line;

Slope (m) = (y₂ - y₁)/(x₂ - x₁)

Slope (m) = -0.7.

At data point (-3, 2) and a slope of -7/10, a linear equation in slope-intercept form for this line can be calculated by using the point-slope form as follows:

y - y₁ = m(x - x₁)

y - 2 = -7/10(x + 3)

y - 2 = -7x/10 - 21/10

The height of the pistol after 10 seconds is 783 feet.

We can use the method of finite differences to find the degree of the polynomial function that models the data. The first differences are:

3, 18, 37, 56, 72

The second differences are:

15, 19, 19, 16

Since the second differences are constant, we know that the function that models the data is a quadratic function of the form:

h(t) = at² + bt + c

where a, b, and c are constants to be determined.

To find a, we can use the fact that the coefficient of t² in the quadratic function is equal to half of the second difference. Thus, we have:

a = 1/2(15) = 7.5

To find b, we can use the fact that the coefficient of t in the quadratic function is equal to the first difference minus twice the coefficient of t². Thus, we have:

b = 18 - 2(7.5) = 3

To find c, we can use the fact that the constant term in the quadratic function is equal to the value of h(0). Thus, we have:

c = h(0) = 3

Therefore, the equation that models the data is:

h(t) = 7.5t² + 3t + 3

To find the height of the pistol after 10 seconds, we can substitute t = 10 into the equation:

h(10) = 7.5(10)² + 3(10) + 3

h(10) = 750 + 30 + 3

h(10) = 783

To find the argument of the complex number z = 1/16 - (sqrt(3)/16)i, we need to find the angle that the complex number forms with the positive real axis in the complex plane.

We can start by finding the magnitude of z, which is the distance between the origin and the point representing z in the complex plane:

|z| = sqrt( (1/16)^2 + (sqrt(3)/16)^2 )

= sqrt(1/256 + 3/256)

= sqrt(4/256)

= 1/4

Next, we can find the argument of z using the formula:

arg(z) = tan^(-1)(Im(z)/Re(z))

where Im(z) is the imaginary part of z, and Re(z) is the real part of z.

In this case, we have:

Re(z) = 1/16

Im(z) = -(sqrt(3)/16)

Therefore, we get:

arg(z) = tan^(-1)(Im(z)/Re(z))

= tan^(-1)(-(sqrt(3)/16)/(1/16))

= tan^(-1)(-sqrt(3))

= -60° (in degrees)

So, the argument of z is -60 degrees (or -π/3 radians).

Answer:

the correct dosage of the medicine for a 145 lb. woman would be approximately 3.22 cc

Step-by-step explanation:

To calculate the correct dosage of the medicine for a 145 lb. woman, we can use the following formula:

dosage = (weight of patient / weight of reference patient) x reference dosage

where the weight of the reference patient is 180 lb. and the reference dosage is 4 cc.

Plugging in the given values, we get:

dosage = (145 / 180) x 4

      = 3.22 cc (rounded to two decimal places)

Therefore, the correct dosage of the medicine for a 145 lb. woman would be approximately 3.22 cc. However, it's important to note that dosages of medications should only be determined by a qualified medical professional based on a number of factors, including the patient's weight, medical history, and current condition.

The calculated value of the angular velocity of the object is 2 rad/s.

The angular velocity, denoted by the Greek letter omega (ω), represents the rate of change of the angle with respect to time.

For an object moving in a circular path, the angular velocity is related to the linear speed and the radius of the circle by the equation:

ω = v/r

where v is the linear speed and r is the radius.

In this case, the radius is 0.5m and the speed is 1ms−1. Thus, the angular velocity is:

ω = v/r = 1/0.5 = 2 radians per second (rad/s)

Therefore, the angular velocity of the object is 2 rad/s.

If r = 0.5 m, A = ???

If after the plumber has worked alone for 3 hours, his apprentice joins him and working together they complete the job 4 hours later, it would take the plumber 9 hours to do the entire job by himself.

Let's start by assigning some b to represent the rate at which each person works. Let's say that the plumber's rate is P (in units of job per hour) and the apprentice's rate is A (also in units of job per hour). Since the plumber works twice as fast as the apprentice, we can write:

P = 2A

Next, let's think about how much work can be done in a certain amount of time. If the plumber works alone for 3 hours, he completes 3P units of work. When the apprentice joins him, they work together for another 4 hours to complete the entire job, which is a total of 7 hours of work. So, the amount of work done in those 4 hours is:

4(P + A)

We also know that the total amount of work is 1 (since it's one complete job). Putting this all together, we can write an equation:

3P + 4(P + A) = 1

We can simplify this to:

7P + 4A = 1

But we also know that P = 2A, so we can substitute that in:

7(2A) + 4A = 1

Simplifying this, we get:

18A = 1

So, A = 1/18. This means that the apprentice can complete 1/18 of the job in one hour. Since the plumber works twice as fast, he can complete 2/18 of the job (or 1/9) in one hour.

To find out how long it would take the plumber to do the entire job by himself, we can use the formula:

Time = Work / Rate

The entire job is 1, and the plumber's rate is 1/9. So:

Time = 1 / (1/9) = 9 hours

360 and 360; the proportion is true.

To find the cross-products of the proportion 6/40 = 9/60, we multiply the numerator of the first fraction by the denominator of the second fraction, and the numerator of the second fraction by the denominator of the first fraction.

So we have:

6 × 60 = 360

9 × 40 = 360

The cross-products are 360 and 360.

To check if the proportion is true, we compare the cross-products. If they are equal, then the proportion is true; otherwise, it is false.

Since the cross-products are equal, the proportion is true.

Therefore, the answer is:
