Answer:
31
Step-by-step explanation:
We need to substitute values of x and y into given formula
40 - (9x) +y² = 40 - (9*2) + 3² = 40 - 18 + 9 = 31
Answer:
A
Step-by-step explanation:
Tangent is opp over adjacent (square root 3 over 1 = square root 3)
Hope that helped! :))
Cot (x) = 3.2404
1/tan(x) = 3.2404
tan(x) = 1 / 3.2404
x = inverse tangent ( 1 / 3.2404 )
x = 72.8 degrees (3 s.f.)
Answer:
$1,200
Step-by-step explanation:
Data provided in the question:
R'(x)= -0.1x + 40
now,
Revenue function = ∫R'(x)= ∫(-0.1x + 40)
or
R(x) =
here, c is the integration constant
also,
at x = 0, Revenue R = 0
thus,
0 =
or
c = 0
therefore,
we get the revenue function as;
R(x) =
a) For x = 230 units
R(230) =
or
R(230) = - 2645 + 9200 = $6,555
b) R(330) =
or
R(330) = -5445 + 13,200 = $7,755
Hence,
the addition evenue realized when the production (and sales) level is increased from 230 to 330 units
= $7,755 - $6,555
= $1,200
