Step-by-step explanation:
It is in the form of a² - b²
so it's correct product is
64x² - 16
A(-4,-3)
B(-3,-1)
C(2,-1)
D(-2,4)
your new points
To find the x value of the max of
f(x)=ax^2+bx+c
when a is negative (if a is positive, we find the minimum)
we do
-b/2a is the x value
to find the y value, we just sub that x value back into the function
so
R(x)=-0.2x^2+60x+0
-b/2a=-60/(2*0.2)=-60/-0.4=150
x value is 150
make 150 units
sub back to find revenue
R(150)=-0.2(150)^2+60(150)
R(150)=-0.2(22500)+9000
R(150)=-4500+9000
R(150)=4500
max revenue is achieved when 150 units are produced yeilding $4500 in revenue
1 hour and 48 minutes plus 1980/550=3.6 so 3 hours and 36 minutes plus 30 minutes so 48+30=1 hour and 18 minutes plus 1 hour = 2 hours and 18 minutes + 3 hours and 36 minutes =5 hours and 54 minutes hope I helped
