Answer:
540 minutes
Step-by-step explanation:
There are 60 minutes in one hour so 9x60=540
#7) y = - x² + 4
Vertex:
∆=b²-4ac
S(-b/2a , -∆/4a) = (0/-2 , -16/-4) = (0,4)
Axis of symmetry:
x=-b/2a = 0
(we have max here because a is negative) Max:
Max (0,4)
#8) f(x) = x² -4x +4
Vertex:
S(-b/2a , -∆/4a) = (4/2 , 0/4) = (2,0)
Axis of symmetry:
x= -b/2a = 2
(Here it's min because a>0) Min:
Min(2,0)
Answer:
you can't do that since its a whole number
Answer:68
Step-by-step explanation:
angle sum property
56+y+y-12=180
44+2y=180
2y=180-44=136
y=136/2
=68
VERIFICATION :56+68+56
=180
<span>The answer is: 1, 2, 7, 14 .

Explanation:
________________________________________________
FIrst, list all the factors of 42 (positive integers):
________________________________________________________
1, 42
2, 21,
3, 14,
6, 7
_________________________________________________
Then list all the factors of 28 (positive integers):
____________________________________________________
<span> 1, 28
2, 14,
4, 7
</span>_____________________________________________________
Now, list all numbers that occur for BOTH the factors of "28" AND the factors of "42"
_____________________________________________________
1, 2, 7, 14
_____________________________________________________
The answer is: 1, 2, 7, 14 .
