Mathematics
1 answer:
Marysya12 [62]2 years ago

Answer:

a. D'(p) = -10p - 6

b. There is a decrease of 96 units of demand for each dollar increase

Step-by-step explanation:

The demand function is:

D(p) = - 5p^2-6p+400

(a) The derivate of the demand function with respect to price gives us the rate of change of demand:

\frac{dD(p)}{dp}=D'(p) = -10p-6

(b) When p = $9, the rate of change of demand is:

D'(9) = -10*9-6\\D'(9) = -96\ \frac{units}{\$}

This means that, when p = $9,  there is a decrease of 96 units of demand for each dollar increase.

Are these rates equivalent, 96 words typed for 3 minutes; 160 words typed for 5 minutes
monitta
<h2>Greetings</h2>

Answer:

Yes, they are.

Step-by-step explanation:

<h3>1st rate)</h3>

Lets simplify both rates to the rate typer per minute.

(m is minutes)

3m = 96

Divide both sides by 3:

\frac{3m}{3} = \frac{96}{3}

m = 32

So the rate is 32 words per minute.

<h3>2nd rate</h3>

5m = 160

Divide both sides by 5:

\frac{5m}{5} = \frac{160}{5}

m = 32

<h3>So because the rates per minute are the same, they are equivalent.</h3>
