The weekly sales of Honolulu Red Oranges is given by q = 896 − 20p.(A) Calculate the price elasticity of demand when the price i

vitfil [10]

Answer with Step-by-step explanation:

Since we have given that

q = 896-20p

p = $32

.(A) Calculate the price elasticity of demand

As we know that

$e=-\dfrac{dq}{dp}\times \dfrac{p}{q}\\\\e=-(-20)\times \dfrac{32}{896-20p}\\\\e=\dfrac{20\times 32}{896-20p}\\\\e=\dfrac{640}{896-20p}\\\\e=\dfrac{640}{896-640}\\\\e=\dfrac{640}{256}=2.5$

(B) The demand is going down with increase in 15 increase in price at that price level, as we know that there is inverse relationship between price and quantity demanded.

(C) Also, calculate the price that gives a maximum weekly revenue.

$R=pq\\\\R=p(896-20p)\\\\R=896p-20p^2$

We first find the first derivative:

$R'(p)=896-400p$

So, it becomes,

$896-40p=0\\\\40p=896\\\\p=\dfrac{896}{40}=\$22.4$

R=-40<0, so, it will give maximum revenue.

(D) Find this maximum revenue.

Maximum revenue would be $R=pq\\\\R=22.4(896-20\times 22.4)\\\\R=\$10035.2$

Factorise the quadratic expression <br>pls help me I'll give brainliest <br>x²+8x-48

pav-90 [236]

$x^2+8x-48\\\\=x^2 + 12x -4x -48\\\\=x(x+12) -4(x+12)\\\\=(x-4)(x+12)$

15) Evaluate the following expression for x=0.2 and y=3.4: x(y2 - 4)

Maslowich

Answer:

x(y² - 4) = 1.512

Step-by-step explanation:

We need to evaluate the following expression for x = 0.2 and y = 3.4 :

x(y² - 4)

Put the values of x and y.

x(y² - 4) = (0.2)((3.4)² - 4)

= (0.2)((3.4)² - 4)

= 0.2×7.56

= 1.512

So, the value of the above expression is 1.512

Factor the quadratic expression. 3x^2-2x-5

PSYCHO15rus [73]

first subtract 2 from - 5 which is 7 then subtract 3-2 then you would get x = 7 that would be my guess.
