Answer:

A= 2pirh +2pir^2

972=2 x pi x x x 5x + 2 x pi x x^2

972= 31.4x^2 + 6.28x^2

972=37.68x^2

x^2= 972/37.68

x^2=25.796

x= 25.796 square root

x= 5

The value of x is 5 cm.

A cylinder is a three-dimensional figure that has a radius and a height.

The volume of a cylinder is given as

Example:

The volume of a cup with a height of 5 cm and a radius of 2 cm is

Volume = 3.14 x 2 x 2 x 5 = 62.8 cubic cm

We have,

The surface area of a cylinder = 972 cm²

The surface area of a cylinder.

= 2πrh + 2πr²

Diameter = 2x

Radius = x

Height = 5x

Now,

2πrh + 2πr² = 972

2π (rh + r²) = 972

2π (5x² + x²) = 972

2π x 6x² = 972

6x² = 972/(2 x 3.14)

6x² = 154.78

x² = 25.79

x = √25.79

x = 5.08

x = 5

Thus,

x value is 5.

Answer:

  55 8/39 N ≈ 55 N

Step-by-step explanation:

The net force on the 1.4 kg block is proportional to its mass. That is, the ratio of net force on that block to the net force on the total mass is the same as the ratio of the block's mass to the total mass.

  net force on 1.4 kg = (1.4 kg)/(1.4 +6.4 kg) × (64 N -15 N) = (7/39)(49 N)

  net force on 1.4 kg = 8 31/39 N

Then the force applied by the 6.4 kg mass is ...

  64 N - 8 31/39 N = 55 8/39 N ≈ 55 N . . . . applied by 6.4 kg mass

Answer:

Please check the explanation.

Step-by-step explanation:

Given the table

Time (h)          Distance (km)

    1                              2

    3                             6

    6                            12

    9                            18

As the time (h) is represented on the x-axis and the distance (km) is represented on the y-axis.

We know that the first coordinate of an ordered pair or point (x, y) is called the x-coordinate and the second coordinate is called the y-coordinate.

Thus, from the table, we get the following points:

(1, 2), (3, 6), (6, 12), and (9, 18)

The given points are plotted on the graph attached below.

From the graph, it is clear that:

Point (1, 2)

Point (1, 2) is represented at x = 1 and y = 2.

Thus, at the point (1, 2):

Speed = Distance / Time = 2/1 = 2km per hour

Point (3, 6)

Point (3, 6) is represented at x = 3 and y = 6.

Thus, at the point (3, 6):

Speed = Distance / Time = 6/3= 2km per hour

Point (6, 12)

Point (6, 12) is represented at x = 6 and y = 12.

Thus, at the point (6, 12):

Speed = Distance / Time = 12/6= 2km per hour

Point (9, 18)

Point (9, 18) is represented at x = 9 and y = 18.

Thus, at the point (9, 18):

Speed = Distance / Time = 18/9= 2km per hour

Answer:

Step-by-step explanation:

6x – 3y = -30

3x – 6y = 12

Multiply the top equation by 2 and write the bottom equation under it.

12x - 6y = - 60

3x - 6y =   12        Subtract

9x = - 72                 Divide by 9

x = - 72/9

x = - 8

6x - 3y = - 30

6*-8 - 3y = -30

-48 - 3y = - 30         Add 48 to both sides.

-3y = - 30 + 48

-3y = 18                   Divide by -3

y = -18/-3

y = -6

y = (4/3)x+7

Slope of the line is 4/3.

Slope of any perpendicular to the line is -¾.

Point-slope equation for line of slope -¾ that passes through (4,11):

y-11 = -¾(x-4)

Of course, you may want to rearrange it to slope-intercept form or standard form.

y = -¾x+15 slope-intercept

x+4y = 60 standard

Answer:

You have to plot these points on the graph and find out what the slope is that way or find the slope using the slope form. (below) Then using the slope add the y-coordinate and x-coordinate to the appropriate places in the ordered pair (-0.5,0) this will give you your answer of ordered pair.

Answer:

The correct answer is c.

Step-by-step explanation:

x  represents the number of the data variable that is being studied and from this data we obtain P, that is, the proportion

P is the proportion that is equal to x / n that is, x is equal to 6.41 that when divided by 458 which is equal to n and multiplied by 100 gives a proportion of 1.4%

P= 6.41÷458×100=1.4%

Answer: 149 cartridges will be sold at 20 dollars per cartridge.

Step-by-step explanation:

Given: The projected sales volume of a video game cartridge is given by the function [tex]s(p)=\dfrac{3000}{2p+a}[/tex], where s is the number of cartridges sold, in thousands; p is the price per cartridge, in dollars; and a is a constant.

Put s(p)=100000, p= 10, we get

[tex]100000=\dfrac{3000}{2(10)+a}\\\\\Rightarrow\ 100=\dfrac{3}{20+a}\\\\\Rightarrow\ 100(20+a)=3\\\\\Rightarrow\ 2000+100a=3\\\\\Rightarrow\ 100a=-1997\\\\\Rightarrow\ a=-19.97[/tex]

i.e. [tex]s(p)=\dfrac{3000}{2p-19.97}[/tex]

Put p=20, we get

[tex]s(20)=\dfrac{3000}{2(20)-19.97}\\\\=\dfrac{3000}{40-19.97}\\\\=\dfrac{3000}{20.03}\approx149[/tex]

Hence, 149 cartridges will be sold at 20 dollars per cartridge.

Using the Fundamental Counting Theorem, it is found that the expression that  gives the number of different  6 -character codes that are possible is:

F. 1(1)(10)(10)(10) (10)

Fundamental counting theorem:

States that if there are n things, each with [tex]n_1, n_2, \cdots, n_n[/tex] ways to be done, each thing independent of the other, the number of ways they can be done is:

[tex]N = n_1 \times n_2 \times \cdots \times n_n[/tex]

In this problem:

Hence:
