Answer:

You = 50 mph

Friend = 30 mph

Step-by-step explanation:

You = $\frac{250-150}{5-2}$ = $\frac{100}{2}$ = 50

Friend = $\frac{240-120}{8-4}$ = $\frac{120}{4}$ = 30

zzz [600]

<h3>Answer: 1/216</h3>

Explanation:

There is only one way to get a sum of 18 and that is rolling three '6's to get 6+6+6 = 18.

There are 6*6*6 = 216 different ways to roll three dice.

Divide the two values to get 1/216

Find the maximum profit and the number of units that must be produced and sold in order to yield the maximum profit. Assume that

Murljashka [212]

Answer:

185 units

Step-by-step explanation:

Given,

The revenue function is,

$R(x) = 4x$

Cost function,

$C(x) = 0.01x^2 + 0.3x + 4$ ,

Where,

x = number of units produced.

Thus, profit = revenue - cost

$P(x) = 4x - ( 0.01x^2 + 0.3x + 4) = -0.01x^2 + 3.7x - 4$

Differentiating with respect to x,

$P'(x) = -0.02x + 3.7$

Again differentiating with respect to x,

$P''(x) = -0.02$

For maxima or minima,

P'(x) = 0,

$-0.02x + 3.7x =0$

$-0.02x = -3.7$

$\implies x = \frac{3.7}{0.02}=185$

For x = 185,

P''(x) = negative,

Hence, for maximising the profit 185 units must be produced.
