Answer:
Step-by-step explanation:
hello :
here is two examples:
1) x²-9=0 means : x²-3² = (x-3)(x+3) = 0 .... use identity : a²-b² = (a-b(a+b)
use the Zero Product Property; x-3=0 or x+3=0 so : x=3 or x= +3
2) x²+4x = 0....using factoring : x(x+4)=0 means : x=0 or x+4=0
x=0 or x= - 4
Answer:
(-1.5,-16)
(1,4)
(2.5,-3)
Step-by-step explanation:
Over the interval (-3,0], the local minimum is (-1.5,-16).
Over the interval [0,3], the local maximum is (1,4).
Over the interval [0,57 , the local minimum is (2.5,-3).
The answer is 21.
2^3 = 8
21 - 13 = 8
Hi there!
The correct answer is C) The administrator's calculation is not reasonable because my estimate of 500 is not close to 408. Let's use rounding to find our estimate. 423 is close to 400 and 931 is close to 900. If we subtract 400 from 900, we know that there was approximately 500 adults. Since 408 is not near 500, the administrator's calculation is not reasonable. In fact, they were 100 off from the correct calculation, also making it not reasonable.
Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
