denis23 [38]

Answer:

Step-by-step explanation:

Given that a  small business assumes that the demand function for one of its new products can be modeled by

p=ce^{kx}

Substitute  the given values for p and x to get two equations in c and k

40 = ce^{1200k} \\45 = ce^{1000k}

Dividing on by other we get

\frac{45}{40} =e^{-200k} \\-200 k = ln (45/40) = 0.117583\\k = -0.000589

Substitute value of k in any one equation

45 = ce^{-0.589} \\c=45.02651

b) Revenue of the product is demand and price

i.e. R(x) = p*x = 45.02651xe^{-0.000589x}

Use Calculus derivative test to find max Revenue

R'(x) = 45.02651 e^{-0.000589x}-45.02651*0.000589 x e^{-0.000589x}\\

EquateI derivative to 0

1-0.000589x =0

x = 1698.037

When x = 1698 and p = 16.56469

The ratio of dogs to cats in a park is 10 to 9. If there are 50 dogs then how many cats are there
serious [3.7K]
Knowing the ratio for dogs to cats is 10:9

To get to 50 dogs they multiplied 10x5

So multiply 9x5 as well to get the number of cats

Cats = 45

:) hope this helps

<span>If a and h are real numbers, find the following values for the given function.
f(x) = 7 − 3x
(a) 
f(a) = 7-3a
------------------------
(b) 
f(−a) = 7-3(-a) = 7+3a
------------------------
(c) 
−f(a) = -(7-3a) = 3a-7
------------------------
(d) 

f(a + h) = 7 -3(a+h) = 7-3a-3h
------------------------
(e) 
f(a) + f(h) = (7-3a)+(7-3h) = 14-3a-3h
------------------------
(f)
if h ≠ 0,

[f(a + h) − f(a)]/h = {[7-3a-3h]-[7-3a]}/h = [-3h]/h = -</span></span>

Ronch [10]

If u had 88$ + 29$ that would be 117 . Now that u got 74 dollars left .you would take 117 ( the total beginning money ) and subtract it from 74 . Equation 117-74=43$ so you spent 43 on on summer tickets ​
