4 bc I’m smart and I passed
Answer:
90
Step-by-step explanation:
so assuming scaled down it is
1:1.5 or
2:3
so
72 is the 3 units
divide 72 by 3
72/3=14
14 times 2=28
the surface area=28 in^2
.. can yall please rate me answer the brainiest please people i need 5
If x is between two consecutive integers such that n ≤ x < n + 1, then the greatest integer function [x] maps x to the largest integer smaller than x so that [x] = n.
(i) If x is approaching -2 from above, that means x > -2. As x gets closer to -2, we essentially have -2 < x < -1, so that [x] will approach
![\displaystyle \lim_{x\to-2^+} [x] = \boxed{-2}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Clim_%7Bx%5Cto-2%5E%2B%7D%20%5Bx%5D%20%3D%20%5Cboxed%7B-2%7D)
(ii) However, if x is approaching -2 from below, then x < -2, so that [x] = -3. In other words
![\displaystyle \lim_{x\to-2^-} [x] = -3 \neq -2](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Clim_%7Bx%5Cto-2%5E-%7D%20%5Bx%5D%20%3D%20-3%20%5Cneq%20-2)
Because the one-sided limits do not match, the two-sided limit
![\displaystyle \lim_{x\to-2} [x] ~~\boxed{\text{does not exist}}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Clim_%7Bx%5Cto-2%7D%20%5Bx%5D%20~~%5Cboxed%7B%5Ctext%7Bdoes%20not%20exist%7D%7D)
(iii) -2.4 lies between -3 and -2, so
![\displaystyle \lim_{x\to-2.4} [x] = \boxed{-3}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Clim_%7Bx%5Cto-2.4%7D%20%5Bx%5D%20%3D%20%5Cboxed%7B-3%7D)
The property is called identity property.
