Answer:

Step-by-step explanation:

For a single cylinder:

radius (r) = 3 in (Given)

height (h) = 8 in (Given)

It is given that: all the three cylinders are identical, means their radii and heights are equal.

Thus, the volume of composite figure will be equal to three times the volume of single cylinder.

Answer:

$V_{composite\: figure} =678.24\: in^3$

Step-by-step explanation:

For a single cylinder:

radius (r) = 3 in (Given)

height (h) = 8 in (Given)

It is given that: all the three cylinders are identical, means their radii and heights are equal.

Thus, the volume of composite figure will be equal to three times the volume of single cylinder.

$\implies V_{composite\: figure} =3(\pi r^2 h)$

$\implies V_{composite\: figure} =3(3.14\times (3)^2 \times 8)$

$\implies V_{composite\: figure} =3(226.08)$

$\implies V_{composite\: figure} =678.24\: in^3$

Suppose that the inverse demand for a downstream firm is P = 150 − Q. Its upstream division produces a critical input with costs

kozerog [31]

Answer:

The marginal revenue is $MT_d = 116.66$

Step-by-step explanation:

From the question we are told that

The inverse demand for a downstream firm is $P = 150 -Q$

The cost of the critical input produced by upstream division is $CU(Q_d) = 5(Q_d)^2$

The cost of the critical input produced by downstream firm is Cd(Q) = 10Q

Generally

The marginal revenue of the downstream firm - The marginal cost of the downstream firm = Net marginal revenue of downstream

i.e

$MR_d - MC_d = MT_d$

Also

The marginal revenue of the downstream firm - The marginal cost of the downstream firm = Marginal upstream cost

i.e

$MR_d - MC_d = MC_u$

Generally the total revenue of downstream firm is mathematically represented as

$TR = P * Q$

Here Q stands for quantity produced by the downstream firm and TR is the total revenue

$TR = [150 - Q] * Q$

=> $TR = 150Q - Q^2$

Generally the marginal revenue of the downstream firm is mathematically evaluated as

$MR_d =\frac{d (TR)}{d Q} = 150 - 2Q$

Generally marginal downstream first cost is mathematically evaluated as

$MC_d = \frac{d(Cd(Q)) }{dQ} = 10$

Generally the net marginal revenue of the downstream firm is mathematically represented as

$150 - 2Q -10 = MT_d$

=> $MT_d = 140 - 2Q$

Generally the marginal upstream cost is mathematically represented a

$MC _u =\frac{d [CU(Q_d)]}{dQ_d} = 10(Q_d)$

Generally $Q_d = Q$ this because $Q_d$ represents the quantity produced by the downstream firm and also Q is associated with the cost of the downstream quantity

$MC _u =\frac{d [CU(Q)]}{dQ} = 10Q$

=> $10(Q) = 140 -2Q$

=> $Q = 11.67$

So the net marginal revenue of the downstream firm is mathematically represented as

=> $MT_d = 140 - 2(11.67)$

=> $MT_d = 116.66$

(easy math question please help) find the value of x question #5

Aleks04 [339]

Answer:

x = 10

Step-by-step explanation:

Angles in a triangle add up to 180°. Using this, we can form the following equation:

71° + 50° + 6x - 1 = 180. A simplified version is this: 120° + 6x = 180

Remove 120° from both sides to get:

6x = 60

Divide both sides to get:

x = 10

Hope this helps!
