Hurry plzzzz i need help!!! 20 points. Describe the graph of the function.
2 answers:
X equals negative 2. It says i need to write at least 20 characters so ignore this part, its nonsense :)
Answer:
the graph is a parabola with axis of symmetry at x=2
Step-by-step explanation:
y = 4x^2 + 16x – 18
To find axis of symmetry we use formula
x= -b/2a
From the given equation , a= 4 , b = 16
Plug in the values in the formula

So x= -2
Hence the graph is a parabola with axis of symmetry at x=2

i think
volume of cylinder = PI*r^2*h
r=11
h=15
using 3.14 for pi
3.14*11^2*15 = 5699.1 units^3
Answer:
-2 would be the answer
64 - (3y + 8y + y) / 40 = 37
Simplify 3y + 8y + y
64 - 12y / 40 = 37
Add 12y / 40 to both sides and subtract 37
27 = 12y / 40
Multiply both sides by 40
1080 = 12y
Divide both sides by 12
90 = y
