It’s 28!!, good luck on whatever your doing
Answer:
Step-by-step explanation:
y - 4 = C(x - 2)²
y-intercept = -3, so x = 0, y = -3
-3 - 4 = C(2)²
so C = -7/4

Answer:
The point of diminishing returns (x , y ) is (11, 21462)
Step-by-step explanation:
From the question we are told that
The function is
Here R(x) represents revenue (in thousands of dollars) and x represents the amount spent on advertising (in thousands of dollars).
Now differentiating R(x) we have
Finding the second derivative of R(x)
at inflection point
So
=>
substituting value of x into R(x)
Now the point of diminishing returns (x , y ) i.e (x , R(x) ) is
(11, 21462)
A = 1/2 bh can be written as
A = bh/2.
2A = (bh/2)(2)
2A = bh
Divide both sides by h to find b.
2A/h = b
Done.
Answer: 109
Step-by-step explanation: Substitute in 4 for m and 5 for n in the equation:
(4)^3 + 9(5)
(4*4*4) +45
(16*4) +45
64+45 =109
Hope this helped!
