how do i calculate the lateral surface area of a cube the length,width,and hieght are all 4

Answers

I don't know if I am correct or not, but I believe that you have to multiply the perimeter of your base and then multiply that by the height of your cube.

So in this case, you would do 4 x 4, since a cube is basically 6 squares, and a square has 4 sides.

4 x 4 = 16

Then the height is 4 as well.

16 x 4 = 64² (I believe you have to square the total as well, so don't forget that.)

If I am incorrect, please let me know. But I really do hope this helped. :)

The seventh and tenth terms of a geometric sequence are 7 and 21 respectively. What is the 13th term of this progression?

Answers

Answer:

Step-by-step explanation:

Each term in a geometric sequence progresses by multiplying a constant (let us name it r).

Let us solve for this constant r in order to find the 13th term.

If the seventh term is 7, the tenth term would be 7*r*r*r, or [tex]7r^{3}[/tex]. We also happen to know that the 10th term is 21. Let us make a new equation:

[tex]7r^{3} =21\\r^{3}=3\\r= \sqrt[3]{3}[/tex]

or, approx. 1.442249570307408

Using the same logic, the 13th term would be 7*r*r*r*r*r*r, or [tex]7r^{6}[/tex]. We may now substitute what we know, r, into this expression to obtain the 13th term:

[tex]7*\sqrt[3]{3}^{6} = \\7*3^{2}=\\7*9=\\63[/tex]

Therefore, the 13th term of this progression is 63.

I hope this helps! Please let me know if you have any further questions :)

In scenario X, a device that can measure the volume of sound is placed on the ground in vacuum. An object, also in vacuum, is released from rest above the ground and falls so that it strikes the ground next to the device. In scenario Y, the experiment is repeated in the same way, except the device and object are not in vacuum. In terms of energy transfer, which of the following claims is correct about the volume of sound produced by the object when it hits the ground in scenario X and scenario Y?a. The measured volume in scenario X is greater than in scenario Y, because sound waves are not impeded by particles in the air as they travel through vacuum. Thus, the sound waves have more energy in scenario X than in scenario Y.b. The measured volume in scenario X is less than in scenario Y, because sound waves must have a medium to transfer energy. Thus, the sound waves have more energy in scenario X than in scenario Y.c. The measured volume in scenario X is the same as in scenario Y, because the experiment is identical in both scenarios except for the amount of air where the experiments are conducted. Thus, the sound waves have equal energies.d. The answer cannot be determined, because the recorded volume of sound is not related to the energy contained within the sound wave. write the equation of the line given the slope m=4 and passes through the point (-2,5) HELP ME I KEEP ON ASKING THIS MY MOM WILL KILL ME!!!
