Answer:
It's A big man
Step-by-step explanation:
White figure Area = 128![\pi](https://tex.z-dn.net/?f=%5Cpi)
White surface area = appro. 301
Yellow area = 320![\pi](https://tex.z-dn.net/?f=%5Cpi)
Yellow Surface area = approx. 653
Area found with = 2πrh+2πr2
Surface Area found with = 2πrh+2πr2
You need to memorize them for tests
Hope that helped!!! k
Answer:
As per the statement: the value of the expression 7 x n/4 greater than 7.
To describe the relationship between n and 4.
"greater than" symbol is represented by '>'
The value of expression
grater than 7 is;
![7(\frac{n}{4}) > 7](https://tex.z-dn.net/?f=7%28%5Cfrac%7Bn%7D%7B4%7D%29%20%3E%207)
Divide by 7 both sides we get;
![\frac{n}{4} > 1](https://tex.z-dn.net/?f=%5Cfrac%7Bn%7D%7B4%7D%20%3E%201)
Multiply both sides of an equation by 4 we get;
![n > 4](https://tex.z-dn.net/?f=n%20%3E%204)
Therefore, the relationship between n and 4 is, ![n > 4](https://tex.z-dn.net/?f=n%20%3E%204)
Find the concavity changes of f(x).
Give the x-coordinates.
So, the answer to the multiple choice question is -1 and 5 since those points are where f''(x) changes sign.
Note: You can tell that you're supposed to find the concavity changes of f(x) and not f''(x) because from the graph it's obvious that the concavity of f"(x) doesn't change.
Answer:
All solutions or infinite.
Step-by-step explanation:
Turn 2y = -4x + 6 into standard form - divide by 2
Y = -2x + 3
2x + y = 3
Substitute the y equation in for y.
2x - 2x + 3 = 3
The x variables cancel out.
3 = 3
Which is true so it means all solutions.
Hope this helps.
