Answer:
Step-by-step explanation:
Do you have the graphs that I can see.
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
A=2w x w
With w being the width of the rug and A being the total area/surface of the rug
6
1.34*10
Just move it to the left 6 times
Answer:
2 * 21
3 * 14
6 * 7
Step-by-step explanation:
7 * 2 = 14
56 - 14 = 42
Multiples of 42 = 2,3,6,7, 14, 21
