Which expression is the completely factored form of x^6– 64y^3?
Answers
Answer:
[tex](x^2-4y)(x^4+4x^2y+16y^2)[/tex]
Step-by-step explanation:
Factoring
We need to recall the following polynomial identity:
[tex](a^3-b^3)(a-b)(a^2+ab+b^2)[/tex]
The given expression is:
[tex]x^6- 64y^3[/tex]
To factor the above expression, we need to find a and b, knowing a^3 and b^3. a is the cubic root of a^3, and b is the cubic root of b^3:
[tex]a=\sqrt[3]{x^6}=x^2[/tex]
[tex]b=\sqrt[3]{64y^3}=4y[/tex]
Now we apply the identity:
[tex]x^6– 64y^3=(x^2-4y)[(x^2)^2+(x^2)*(4y)+(4y)^2][/tex]
Operating:
[tex]x^6– 64y^3=(x^2-4y)[x^4+4x^2y+16y^2][/tex]
The remaining factors cannot be factored in anymore. Thus the completely factored form is:
[tex]\boxed{(x^2-4y)(x^4+4x^2y+16y^2)}[/tex]

Step-by-step explanation:
Lets start with [tex]\sqrt{83} - 12[/tex]. First you need to find the square root of 83, which is 9.1104. Right after you get the square root of 83 you need to subtract 12 which will give you -2.8895. For the second part of question one (in the image you provided), we will be doing [tex]\sqrt{49} - 10[/tex]. We will start by finding the square root of 49, which is very simple. It's 7. You would then subtract 10 from 7 which gives you -3. And finally for question 1, you have to compare -2.8895 and -3 and determine which number is greater. Which is -2.8895, so you would put >.For the 2nd question, we will start with [tex]2 + \sqrt{7}[/tex]. First, let's get the square root of 7, which is 2.6457. Now we simply add 2! You should now end up with 4.6457. Now for [tex]\sqrt{17} -1[/tex], you need to get the square root of 17, which is 4.1231. Now just simply subtract 1. You should end up with 3.1231. Now just find which number is greater. Which is 4.6457. You should put > as your answer.For the final question, we will start with [tex]15-\sqrt{15}[/tex]. Just start by getting the square root of 15, which is 3.8729. Then simply subtract 15! You should have -11.1270 as your answer. And for [tex]\sqrt{10} + 4[/tex]. Just get the square root of 10 to start which will be 3.1622. Now finally, add 4! You should get 7.1622 as your answer. Now for the final step, find the greatest number, which is 7.1622, you would then answer < for your final questionIf you have any questions just ask them below. Thank you!

Item 21 A teacher is making identical activity packets using 92 crayons and 23 sheets of paper. What is the greatest number of packets the teacher can make with no items left over? Item 21 A teacher is making identical activity packets using 92 crayons and 23 sheets of paper. What is the greatest number of packets the teacher can make with no items left over?
Answers
Answer:
The greatest number of packets the teacher can make with no items left over is 23.
Step-by-step explanation:
Total number of crayons = 92
Total number of sheets of paper = 23
To find the greatest number of packets the teacher can make with no items left over, find Highest Common Factor (H.C.F) of 92 and 23
92 = [tex]2^2[/tex] × 23
23 = 23
So,
H.C.F(92,23) = 23
Therefore, the greatest number of packets the teacher can make with no items left over is 23.

Answer:
Use the ABS function to find the absolute value of a number. The absolute value of a non-negative number (a positive number, or zero), is the same number. For example, the absolute value of 4 is 4.
Step-by-step explanation:
Explanation: The absolute value is defined as the distance from a number to 0 , and so it is always positive. So, the absolute value of −6 will be the distance from −6 to 0 on the number line, and it is 6
Absolute value is how far the number is from 0. -6 is 6 away from 0, so therefore the absolute value is 6.

An engineer is building a bridge that should be able to hold a maximum weight of 1 ton. He builds a model of the bridge that is exactly 4 times smaller than the actual bridge. 16 ounces = 1 pound. 2,000 pounds = 1 ton. If a test of the model shows that it holds 8,000 ounces, will the bridge hold 1 ton? 8,000 ounces on the model is equal to ounces on the actual bridge. Convert ounces to pounds. The actual bridge can hold pounds. Therefore, the bridge hold 1 ton.
Answers
Answer:
The bridge can hold 1 ton
Step-by-step explanation:
Given that :
Model of bridge built is exactly 4 times smaller than actual bridge
Model bridge : actual bridge
1 : 4
From test,
Model bridge can hold 8000 ounces
Since actual bridge is 4 times the model bridge,;
Then, actual bridge should hold (8000 * 4) ounces = 32000 ounces
16 ounces = 1 pound
2000 pound = 1 ton
Hence,
32,000 ounces = (32000 / 16) pounds = 2000 pounds
Hence,
2000 pounds = 1 ton
Answer: 1 ton

A local zoo has two large snakes. The anaconda is currently 5.23 meters long and grows 1.27 meters every month. The python is 4.76 meters long and grows 2.04 meters per month. How many months (m) does the zookeeper need to wait for the two snakes to be the same length?
Answers
Answer:
Kindly check explanation
Step-by-step explanation:
Given that:
Anaconda:
Current length = 5.23metres
Growth rate = 1.27 metres per month
Python :
Current length = 4.76metres
Growth rate = 2.04metres per month
Number of months (m) in which both will be of the same length:
Anaconda = python
5.23 + 1.27m = 4.76 + 2.04m
Solve for m
5.23 - 4.76 = 2.04m - 1.27m
0.47 = 0.77m
0.47 / 0.77 = 0.77m / 0.77
0.610 = m
