Answer:

74.5

Suppose a baby food company has determined that its total revenue R for its food is given by R = − x 3 + 39 x 2 + 945 x where R
Paraphin [41]

Answer:

35,000 units

Step-by-step explanation:

Total revenue is:

R = -x^3+39x^2+945x

The maximum revenue is attained at the production level for which the derivate of the revenue function is zero:

R = -x^3+39x^2+945x\\R'=0=-3x^2+78x+945\\x=\frac{-b\pm\sqrt{78^2-(4*(-3)*945)} }{-6}\\x_1=35\\x_2=-9

Since production cannot be negative, revenue will be at a maximum when x = 35, or when the production level is 35,000 units.

(9x²+24x-8)-(5x²+3x+10)
motikmotik

Answer:

4x^2 + 21x - 18

Step-by-step explanation:

(9x^2+24x-8)-(5x^2+3x+10)

9x^2+24x-8-5x^2-3x-10

9x^2 - 5x^2 = 4x^2

24x - 3x = 21x

-8 - 10 = -18

Answer: 4x^2 + 21x - 18

question says ; miranda has $3.60 in quarters and nickels in her piggy bank. which equation could be solved to find the possible
Jobisdone [24]
To find the relation between them, you need transform them to the same currency. Let's transform them to cents.
$3.60 = 360 cents.
One quarter is 25 cents, and one nickel is 5 cents.

So 360 = 25q  + 5n

Hope this helps! :D
