Answer:

the answer is -0.5.

Step-by-step explanation: First subtract 17 from 15 to know what u need to get. Know that u get -2, we have to figure out what to do to get -2 out of 4. First to get positive 2, multiply by 0.5, than since we need to get negative 2, add a negative in front. Hence, the answer is -0.5 .

your equation would read

4•x+17=15

so 4 times what plus 17 is 15?

4•-0.5+17=15

Find the value of f(3) for the function.<br> f(a)=2(a+4)-3<br> f(3)=___ (simplify your answer)

Nonamiya [84]

Answer:

<h3>Given =><em><u> </u></em><em><u>f(a)=2(a+4)-3</u></em></h3><h3>To Attain=> <em><u>The value of f(3) for the function</u></em></h3>

Step-by-step explanation:

• By Putting the value of a = 3

•f(a)=2(a+4)-3

=>

$f(3) = 2(3 + 4) - 3 \\ f(3) = 2 \times 7 - 3 \\ f(3) = 14 - 3 \\ f(3) = 11$

• Hence, <em><u>1</u></em><em><u>1</u></em><em><u> </u></em><em><u>is </u></em><em><u>the </u></em><em><u>solution</u></em><em><u> </u></em><em><u>to </u></em><em><u>the </u></em><em><u>function</u></em><em><u> </u></em>

The total monthly profit for a firm is P(x)=6400x−18x^2− (1/3)x^3−40000 dollars, where x is the number of units sold. A maximum

wlad13 [49]

Answer:

Maximum profits are earned when x = 64 that is when 64 units are sold.

Maximum Profit = P(64) = 2,08,490.666667$

Step-by-step explanation:

We are given the following information: $P(x) = 6400x - 18x^2 - \frac{x^3}{3} - 40000$ , where P(x) is the profit function.

We will use double derivative test to find maximum profit.

Differentiating P(x) with respect to x and equating to zero, we get,

$\displaystyle\frac{d(P(x))}{dx} = 6400 - 36x - x^2$

Equating it to zero we get,

$x^2 + 36x - 6400 = 0$

We use the quadratic formula to find the values of x:

$x = \displaystyle\frac{-b \pm \sqrt{b^2 - 4ac} }{2a}$ , where a, b and c are coefficients of $x^2, x^1 , x^0$ respectively.

Putting these value we get x = -100, 64

Now, again differentiating

$\displaystyle\frac{d^2(P(x))}{dx^2} = -36 - 2x$

At x = 64, $\displaystyle\frac{d^2(P(x))}{dx^2} < 0$

Hence, maxima occurs at x = 64.

Therefore, maximum profits are earned when x = 64 that is when 64 units are sold.

Maximum Profit = P(64) = 2,08,490.666667$
