Answer:
<em>False</em>
Step-by-step explanation:
took the test
In form f(x)=ax^2+bx+c
the axis of symmetry is -b/2a so
3/2=-b/2a
given
f(x)=3x^2+bx+4
a=3
b=b
-b/(2*3)=3/2
-b/6=3/2
-b=18/2
-b=9
b=-9
Answer:
$59
Step-by-step explanation:
You first need to find what 18, 27, and 36 can all fit into.
108 is divisible by each of these values:
108/18= 6 108/27=4 108/36=3
This will equate to how many packages of each item you will need:
6 pkgs of Plates, 4 pkgs of Cups, 3 pkgs of Forks
6*$2=12 4*$8=32 3*$5=15
Add these values to find total: 12+32+15=$59

13C3 =286
Option D
Prob of taking 3 cherry from 11 cherries is
6C3/11C3=20/165=0.1212
Option B
(x+4)(x-2) FOIL the roots
x^2 + 2x - 8
a = 1
b = 2
c = -8
