Answer:63

Step-by-step explanation:

42÷2×(11-8)

We are going to resolve the bracket part first ,because bracket comes first in BODMAS,in BODMAS B=bracket O=of D=division M=multiplication A=addition S=subtraction.

After resolving the bracket part we get 42÷2×3 also in BODMAS division comes first before multiplication,so we divide and get

21×3 finally 21×3=63

Find the maximum revenue for the revenue function r(x) = 382 x − 0.6x 2. (round your answer to the nearest cent.)

Gwar [14]

The coefficient of x² is is a negative 0.6, so this function has a maximum value.
the max value of a quadratic function is the value of f(x) when x=-b/2a,
in this case, a=-0.6, b=382
so x=382/1.2=
r(382/1.2)=-0.6(382/1.2)²+382*(382/1.2)
use a calculator: 60801.67 is the number I got.
