The height of cylinder when volume of 480 cubic meters is  480/r^2.

Volume serves as a measure for an object's storage capacity. For instance, a cup's volume is said to be 100 ml if it can hold 100 ml of water when filled to the brim. The amount of space a three-dimensional object occupies is another way to define volume.

A solid's volume can be calculated by counting how many unit cubes it contains, such as in the case of a cube or cuboid. The best way to understand volume is to think of it as the area surrounded or occupied by any solid object or object with three dimensions. This can be seen by performing the following easy exercise at home:

volume of cylinder V is = πr²h

where, r  = radius of cylinder

h = height of cylinder

V = 480π cubic meters

Now, calculate its height in terms of cylinder radius using the volume of cylinder formula:

V = πr²h

480π =  πr²h

h = 480π/ πr²2

h = 480/r²

Therefore, The height of cylinder when volume of 480π is  480/r².

Since in this group of ordered pairs shown above, the x-values are inputs and the y-values are outputs, all the statements that are true include the following:

A. There is only one input for every output.

B. There is only one output for every input.

An ordered pair can be defined as a pair of two (2) elements or points that are commonly written in a fixed order within parentheses as (x, y), which represents the x-coordinate or x-axis (abscissa) and the y-coordinate or y-axis (ordinate) on the coordinate plane of any graph.

Generally speaking, the values on the x-coordinate or x-axis (abscissa) of any graph represents all of the input values while the values on the y-coordinate or y-axis (ordinate) of any graph represents all of the output values.

In this context, we can reasonably and logically deduce that there is a unique input for every output and a unique output for every input.

Answer:

Step-by-step explanation:

You want the initial population and the population after 4 hours if its doubling time is 15 minutes, and the population is 60,000 after 110 minutes.

We like to use the numbers in the problem when writing the exponential equation. Here, we are given a doubling time and a population that is ...

  (minutes, population) = (110, 60000)

We can put these numbers in the form ...

  p(t) = (value at t1) · (growth factor)^((t -t1)/(growth period))

where the growth factor (2) is applicable over the growth period (15 minutes).

This makes our equation ...

  p(t) = 60000(2^((t-110)/15))

We want to find p(0) and p(240). (240 is the number of minutes in 4 hours). The attachment shows the calculations.

The population at t=0 was about 372.

The population after 4 hours will be 24,382,480.

__

Additional comment

A lot of times, you'll see this rewritten as an exponential equation with 'e' as the base. Here, that would be ...

  p(t) = 372·e^(0.0452098t)

where 372 = p(0) = 60000·2^(-110/15), and 0.0452098 ≈ ln(2)/15

These rounded numbers don't give the problem statement values exactly:

  p(110) = 53743, not 60000, for example. You would get a population of 60000 after 112.4 minutes (approximately).

The Volume of the model sphere is given as

Given that the diameter is 5inches, the radius will be

substituting r in the formula will give

Hence, the volume of the model sphere is approximately 321.39 cubic inches

Answer:

Part A:

Option 1

3x + 8 = 5x - 20 (vertically opposite angles)

2x = 28

x = 14

3x + 8 + 5x + 4y = 180° (adjacent angles on a straight line)

8x + 4y = 172

Substitute x = 14 into equation to find y.

8(14) + 4y = 172

4y = 60

y = 15

Hence, x = 14 and y = 15.

Part B:

Option 4

Unlabeled angle = 5x + 4y (vertically opposite angles)

Substitute x and y to find angle measure.

5(14) + 4(15) = 130°

Hence, measure of unlabeled angle is 130°.

The number of people who ride the bus is 70 students.

From the information, at the school, there are 7 students who ride the bus to school for every 4 students who do not ride the bus.

Therefore, the number of people who ride the bus if there are 40 people who do not take the bus will be represented by x.

This will be illustrated as:

4/7 = 40/x

Cross multiply

4x = 40 × 7

4x = 280

Divide

x = 280/4

x = 70

where (x,y) and (xo,yo) are two points on the vector.

In this case, we can use (xo,yo) = R(-2,12) and (x,y) = S(-7,6). By replacing these values into the expression for vector v, we obtain:

Now, consider that the magnitude of v is the square root of the sum of the squares of the components. Then, we have for the magnitud of v:

Hence, the magnitude of v is approximately 7.810.

Now, consider that the tangent of the angle of the direction of the vector is equal to the quotient between the y component over the x component of the vector:

The equation of a linear model to describe the data is 14x - y = 26904

To find a linear equation of the provided data,

Let us put the number of legislature on the y axis and the year corresponding at the x axis,

According to provided information,

In year 2003, the number of legislature is 1138.

In year 2009, the number of legislature is 1222.

So here we have two points,

A(2003,1138) and B(2009,1222).

As we have two points now,

We can use the two point form of the line to find the equation of line,

It says if we have two point (a,b) and (c,d), then the equation of line is,

(y-b)/(x-a) = (d-b)/(c-a)

So, our equation of line is with points A and B is,

(y - 1138)/(x-2003) = (1222-1138)/(2009-2003)

(y-1138)/(x-2003) = 14

y - 1138 = 14x - 28042

14x - y = 26904

When,

x = 2000, y = n,

The probability that the entire cargo will be approved is 0.078 = 7.8% using the Binomial probability distribution, while 92.2% will be refused. As a result, many will be rejected.

By Binomial probability distribution,

P(X = x) = [tex]C_{n,x}[/tex] × [tex]p^{x}[/tex] × [tex](1-p)^{n-x}[/tex]

[tex]C_{n,x}[/tex] , various combinations of x items from a collection of n elements given by,

[tex]C_{n,x}[/tex] = n! ÷ x! (n - x)!

n=42, as 42 tablets are tested.

p=0.06 as 6% is defective.

If at most there is 1 defective piece then it will be accepted.

Therefore,

P(X ≤ 1) = P(X = 0) + P(X = 1)

P(X = x) = [tex]C_{n,x}[/tex] × [tex]p^{x}[/tex] × [tex](1-p)^{n-x}[/tex]

P(X = 0) = [tex]C_{42,0}[/tex] × [tex](0.06)^{0}[/tex] × [tex](0.94)^{42}[/tex] = 0.074

P(X = 1) = [tex]C_{42,1}[/tex] × [tex](0.06)^{1}[/tex] × [tex](0.94)^{41}[/tex] = 0.0047

Thus,

P(X ≤ 1) = P(X = 0) + P(X = 1)

P(X ≤ 1) = 0.074 + 0.0047

P(X ≤ 1) = 0.0787
