Zoom in I think I know this
Step-by-step explanation:
a) Let y = f(x) = 3x - 2x^2
f(-2) = 3(-2) - 2(-2)^2 = p
= -6 - 8
= -14
= p
f(2.5) = 3(2.5) - 2(2.5)^2 = q
= 7.5 - 12.5
= -5
= q
b) graphing
c) From the graph, you should be able to verify the following:
i) f(0.5) = 3(0.5) - 2(0.5)^2 = 1
ii) 0.5 = 3x - 2x^2 or x = 1.3, 0.2
iii) the maximum occurs at
f(0.75) = 1.125
d) the equation for the line of symmetry is x = 0.75
The formula for the volume of a cylinder is V = πr^2h
From the problem r = 4, h = 21 and you use 3.14 for pi
Volume = 3.14 * 4^2 * 21
Volume = 1055.04 cubic feet
Answer:
u forgot pic lol
Step-by-step explanation:
0.07 - 2.69 = -2.62
X = -2.62
Explanation:
I’ve just done a lot of math
Hope this helps!
