Hello!
160÷56= 2.86
You can figure out how many times a number goes into another number by dividing the bigger number by the smaller number.
Hope that made sense!
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
Answer:
Step-by-step explanation:
the simpliest form is 
The answer is C (10.89 m)
x * 9 = 98 m²
x = 98 ÷ 9
x = 10.888888 or 10.89 m
