There are two right circular cylinders. The radius of the first cylinder is 3 centimeters, and its height is 5 centimeters. The radius of the second cylinder is 15 centimeters, but its height is also 5 centimeters. What is the ratio of the volume of the second cylinder to the volume of the first cylinder?

Answers

Answer 1

The ratio of the volume of the second cylinder to the volume of the first cylinder is 25.

To find the ratio of the volume of the second cylinder to the volume of the first cylinder, we need to calculate the volumes of both cylinders and then compare them.

The formula to calculate the volume of a right circular cylinder is given by V = πr^2h, where V represents the volume, r is the radius, and h is the height.

For the first cylinder:

Radius (r₁) = 3 centimeters

Height (h₁) = 5 centimeters

Volume of the first cylinder (V₁) = π * (3 cm)^2 * 5 cm

                             = 45π cm³

For the second cylinder:

Radius (r₂) = 15 centimeters

Height (h₂) = 5 centimeters

Volume of the second cylinder (V₂) = π * (15 cm)^2 * 5 cm

                              = 1125π cm³

To find the ratio of the volumes, we divide the volume of the second cylinder by the volume of the first cylinder:

Ratio = V₂ / V₁

     = (1125π cm³) / (45π cm³)

     = 25

Therefore, the ratio of the volume of the second cylinder to the volume of the first cylinder is 25.

A line passes through point (9, -2) and has a slope of - 2/3
Write an equation in Ax+By = C form for this line.
Use integers for A, B, and C.

Answers

The equation -2/3x + y = -2 is in the slope-intercept form, which is a common form for linear equations.

What is the slope of the equation?

The slope of a line is a measure of its steepness. Mathematically, the slope is calculated as "rise over run" (change in y divided by change in x).

we can use the two-point form to find the equation of the line:

y - y1 = m(x - x1)

Substituting the coordinates of the given point and the slope, we get:

y - (-2) = (-2/3)(x - 9)

Combining like terms and multiplying through the parentheses, we get:

y + 2 = -2/3x + 6

This equation is already in the form Ax + By = C, so we can simply use it as is:

-2/3x + y + 2 = 0

This equation can also be written as -2x + 3y = -6 by multiplying all the terms by 3 to get rid of the fraction.

The equation -2/3x + y = -2 is in the slope-intercept form, which is a common form for linear equations. In this form, the coefficient of x (-2/3) is the slope of the line, and the constant term (-2) is the y-intercept, which is the point where the line intersects the y-axis.

Hence, The equation -2/3x + y = -2 is in the slope-intercept form, which is a common form for linear equations.

B) 2 from A and 2 from B = 29070

C) All from A = 3060

D) 4 people regardless of department = 73815

E) at least 3 from department A = 19380

In math combination technique is used to determines the number of possible arrangements in a collection of items where the order of the selection does not matter.

Here we have given that 4-person grievance committee is to be selected out of 2 how many ways can the following committees be selected

And we need to find the following

Here we know that  4-person grievance committee is to be selected out of 2 departments, A and B, with 18 and 20 people.

In this one we have to find the number ways can the following committees be selected.

A) While the first condition is to 3 from A and 1 from B

Here the term "and" means to multiply

Then it can be written as

=> (18 people choose 3) x (20 people choose 1)

=> (18C3)(20C1) = (816)(20) = 16320

B) And then the next condition is 2 from A and 2 from B

In this one is written as,

=> (18 people choose 2) x (20 people choose 2)

=> (18C2)(20C2) = (153)(190) = 29070

C) All from A

which is equal to the following,

=> 18 people choose 4 = 18C4 = 3060

D) Next, we have to do the calculation for 4 people regardless of department

=> 18+20 or 38 people choose 4 = 38C4 = 73815

E) Finally, at least 3 from department A.

'In other words, it can be written as choose 3 from department A and choose 1 from department B or  Choose 4 all from department A

Where "And" means to multiply and "or" means to add.

Therefore, the condition is written as,

=> [(18 people choose 3) times (20 people choose 1)] plus  (18 people choose 4)

=> (18C3)(20C1) + (18C4) = (816)(20) + 3060 = 19380

Statistic value t=2.27

p-value: < 0.00001

To obtain information on the corrosion-resistance properties of a certain type of steel conduit a random sample of 45 specimens was taken and buried for two years.

The study variable is:

X: Max. penetration of a steel conduit.

The data of the sample

n= 45

sample mean X[bar]= 52.9

sample standard deviation S= 4.2

The conduits are manufactured to have a true average penetration of at most 50 mills, symbolically: μ ≤ 50

The hypothesis is:

H₀: μ ≤ 50

H₁: μ > 50

α: 0.05

To choose the corresponding statistic to use to study the population mean, the variable must have a normal distribution. There is no available information to check this, so I'll just assume that the variable has a normal distribution and, since the population variance is unknown and the sample is small, the statistic to use is a Student t.

Under the null hypothesis, the critical region and the p-value are one-tailed.

Critical value: [tex]t_{n- 1;1-\alpha} =t_{44;0.95} =1.68[/tex]

Rejection rule:

Reject the null hypothesis when t ≥ 1.68

t= [tex]\frac{52.9-50}{\frac{4.2}{\sqrt{45} } }[/tex]

t= 2.9-0.626 = 2.27

If the calculated value is greater than the critical value, the decision is to reject the null hypothesis.

p-value:

P(t ≥ 2.27) = 1 - P(t < 2.27) = < 0.00001.

The p-value is less than α so the decision is to reject the null hypothesis.

Since the null hypothesis was rejected, then the population average of the penetration of the conduits specimens is greater than 50 mils. It is not recommendable to use these conduits.

A solid object's surface area is a measurement of the overall space that the object's surface takes up. It is also known as the overall area of a three-dimensional shape's surface. The formula to calculate surface area is S = 2(xy+yz+zx) where x is length, y is width and z is the height of the object.  

Given the volume is 4096 cm³.

Then, V = xyz = 4096. Deriving the value of z from this, we get z = 4096/xy. Substitute value of z in S = 2(xy+yz+zx), we get,

How to calculate center of the circle ?

The standard equation of a circle is expressed as:

x²+y²+2gx+2fy+C = 0

Centre is (-g, -f)

radius = √g²+f²-C

Given a circle whose equation is x²+y² - 2x- 8 = 0

Get the center of the circle

2gx = -2x

2g = -2

g = -1

Similarly, 2fy = 0

f = 0

Centre = (-(-1), 0) = (1, 0)

This shows that the center of the circle lies on the x-axis

r = radius = √g²+f²-C

radius = √1²+0²-(-8)

radius =√9 = 3 units

The radius of the circle is 3 units.

For the circle x² + y² = 9, the radius is expressed as:

Then, y = 1.6x + b

For points (48,50) then,

or, 50 = 1.6*48 + b

or, 50 = 76.8 + b

or, b = 50 - 76.8 = -26.8

Then, the equation will be

y = 1.6x - 26.8

So, for y = 25 then x becomes

25 = 1.6x - 26.8

or, 1.6x = 25 + 26.8

or, 1.6x = 51.8

or, x = 32.4

Hence, the required value of x is 32.4.

The pressure of 28 inches of mercury occurs about 6 miles from the eye of the hurricane. We get this from the given algebraic expression.

What is an expression?

An expression is formed by variables, constants, and algebraic operations. Since the operation among them is an algebraic or arithmetic operation, it is said to be an algebraic expression.

Calculation:

It is given that the algebraic expression that relates the barometric pressure and the eye of the hurricane as

f(x) = 0.48 ln(x+2) + 27

Here x is the distance in miles from the eye of the hurricane.

f(x) is the pressure of the mercury in a barometer in inches

So, the required distance from the eye of the hurricane when the pressure of 28 inches of mercury in the meter is

(Here f(x) = 28)

f(x) = 0.48 ln(x+2) + 27

⇒ 28 = 0.48 ln(x+2) + 27

⇒ 0.48 ln(x+2) = 28 - 27

⇒ ln (x+2) = 1/0.48

⇒ ln(x+2) = 2.0833

Applying exponential base "e" on both sides, we get

(x+2) = [tex]e^{2.0833}[/tex]

⇒ x + 2 = 8.0309

⇒ x = 8.0309 - 2 = 6.0309

When the result is rounded to the nearest whole number, we get x = 6 miles.

Thus, for the pressure of 28 inches of mercury, the eye of the hurricane is 6 miles far from the barometer.

Willa Schaefer deposited $3,000 in a savings plan with her credit
union. The credit union savings plan pays 3% interest compounded
semiannually. If she makes no other deposits or withdrawals:
a. What is the amount in the account after 2½ years?
b. How much interest did her money earn?
c. What is the amount in the account after 4 years?
d. How much interest did her money earn?

Answers

The amount in the account after 2½ years is $3231.85 and the interest is $231.85

The amount in the account after 4 years is $3379.47and the interest is $379.47

How to determine the amount and the interest?

The amount after 2½ years

The given variables can be represented as:

Deposit amount P = $3,000

Rate of interest, R = 3%

Time, t = 2½ years

The amount from compound interest formula can be calculated as:

A = P(1 + r/n)^nt

Also from the question, we have

n = 2 i.e. compounded semi-annually.

Solving further, we replace the variables with their values in the above equation

A = 3000 * (1 + (3%/2))^(2*2.5)

Evaluate

A = 3231.85

The interest is

I = 3231.85 - 3000

I = 231.85

The amount after 4 years

Here, we have

Time, t = 4 years

The amount from compound interest formula can be calculated as:

A = P(1 + r/n)^nt

Solving further, we replace the variables with their values in the above equation

A = 3000 * (1 + (3%/2))^(2*4)

Evaluate

A = 3379.47

The interest is

I = 3379.47 - 3000

I = 379.47

So, the interest is 379.47

Answers

Triangle ABC is equilateral and hence proved.

According to the question,

Let ABC be a triangle

And the given points A1, B1, and C1 are on its sides BC, AC, and AB respectively

Since according to the first equality says that A1, B1, and C1 are not the midpoints and just normal points on the lines.

According to what equality says that ΔABC = ΔA1B1C1 because the sides are in proportion.

Let us consider 3 more triangles = ΔAB1C1, ΔBC1A1, and ΔCA1B1

Now, these above-mentioned triangles will also be similar due to the proportionality insides.

Which results in ⇒ ∠A = ∠B = ∠C due to the phenomenon of corresponding angles of triangles.  

Therefore, Triangle ABC is equilateral and hence proved.

3. provide an equation for converting gain g in db to a linear scale. for example, a 6db gain translates to a factor of 2, so y[n]

Answers

The equation for converting gain in decibels to a linear scale is dB → gain-multiplier: [tex]g=2^{\frac{d}6} }[/tex]

gain-multiplier → dB: [tex]6*log_{2} g[/tex]

The decibel is used in a wide range of applications. Decibels are especially used when referring to power or a derived measure, which values can vary in a wide range. The most prominent usage of decibels is in sound volume. So, for example, a sound of 0dB is barely hearable, whereas a vacuum cleaner on average has 75dB and a rock concert reaches about 110 dB.

Practical version-

dB → gain-multiplier: [tex]g=2^{\frac{d}6} }[/tex]

gain-multiplier → dB: [tex]6*log_{2} g[/tex]

So if we set that 0 dB gain as 1.0 factor, and -∞ dB gain is 0.0 factor, it means that (if we are considering voltage gain as in a mixing desk fader) :

gain = 20.0*log10(factor)

therefore :

factor = 10^(gain/20.0)

If, as described in a comment, the 0 dB gain is at 0.65 factor, it means the ref is 0.65.

gain in dB = 20*log10(factor/0.65)

factor = 0.65*10^(gain/20.0)

How to change the subject of the formula?

a) We are given that;

r = 1/(x - 1)

We are asked to make x the subject of the formula in terms of r. Thus;

Multiply both sides by (x - 1) to get;

rx - r = 1

r + 1 = xr

x = (r + 1)/r

b) We are given that;

xr + ²/₃ = 2r

Put (r + 1)/r for x to get;

r(r + 1)/r + ²/₃ = 2r

r + 1 + ²/₃ = 2r

1 + ²/₃ = r

r = 5/3

Put 5/3 for r into the x equation to get;

x = ((5/3) + 1)/(5/3)

The value of x in the triangles is 24.5

How to determine the value of x?

From the question, we have the following parameters that can be used in our computation:

The triangle

On the triangle, we have the following ratio

7 + x : x = 27 : 27 - 6

Evaluate the difference

7 + x : x = 27 : 21

Express as fraction

This gives

x/(x + 7) =21/27

So, we have

27x = 21(x + 7)

Expand

27x - 21x = 147

So, we have

6x = 147

Evaluate

x = 24.5

(a) February 4 and November 3 of the year have about 9 h of daylight.

(b) 271 days with more than 9 hours of daylight.

What is a function?

A function, according to a technical definition, is a relationship between a set of inputs and a set of potential outputs, where each input is connected to precisely one output.

Here, we have

Given

(a) L(t) = 11+ 2.86 sin(2π/365 (t-80))

L(t) = 9

9 = 11+ 2.86 sin(2π/365 (t-80))

-2 = 2.86 sin(2π/365 (t-80))

-2/2.86 = sin(2π/365 (t-80))

-2/2.86 = -0.6993

Sin function is negative on [π, 3π/2] and [3π/2, 2π]

sin⁻¹(-0.6993) = 2π/365 (t-80)

2π/365 (t-80) = 3.9160 or 5.5087

t = 80 + 365/2π(3.9160 or 5.5087)

t = 35 or 307

After January 31 days and February 4 days

For t = 35 days =  February 4

For t =307days = November 3

Hence, February 4 and November 3 of the year have about 9 h of daylight.

(b) There are 35 + (365-307) = 35 + 58 = 94 days with 9 hours or less

Hence, 365 - 94 = 271 days with more than 9 hours of daylight.
