I would help but I honestly did not understand this at all when I took Geometry last year. Also you have very pretty handwriting
Answer:
Volume
=
w (width)
h (Height)
l (Length)
Step-by-step explanation:
For this case what you should be aware of is that the root does not take negative values.
We then have to be aware of the domain of the function.
Note: see attached graphic.
Ansewer the domain of the graph is all real number less than or equal to 0 option 3
Answer:
c) 18 units
d) 1 second
Step-by-step explanation:
h = -16t² - 4t + 20
c) t = 0.25
h = -16(0.25)² - 4(0.25) + 20
h = 18
d) -16t² - 4t + 20 = 0
4t² + t - 5 = 0
4t² + 5t - 4t - 5 = 0
t(4t + 5) - (4t + 5) = 9
(4t + 5)(t - 1) = 0
t = -1.25, 1
t = 1 second
