Y= -2x²-3x+2, (form y = ax² +b .x + c
The parabola opens downward & hence it's Vertex is a MAXIMUM.
We know that the axis of symmetry is -b/2a ==>3/(-4) ==>
x= - 3/4 (axis of symmetry. At x=-3/4 , y = 25/8 = 3.125
Hence the axis of symmetry is x= - 3/4 & the vertex is at (-3/4, 25/8)
(-12)^9 is a negative because a negative times a positive is negative. The answer to (-12)^9 is -5159780352.
Hope you learned something :)
Where's your numbers?
Can't help because I have no information, sorry
A toy company produces rubber balls that have a radius of 1.7 cm.
What is the volume of one rubber ball? Round to the
nearest hundredth of a centimeter.
20.58 cm3
If the price of the rubber needed to produce a ball is
$0.0045/cm3, what is the cost of producing one ball?
Round to the nearest cent.
If the company sells a ball for $0.50, how much profit
will it make on each ball?
$1.7 cm
20.58 cm^3, $0.09, $0.41
Hope this helps
