Answer:  A) when Celsius (c) = 0, then Fahrenheit (F) = 32

               B) F(100) = 212°

               C) F(25) = 77°

<u>Step-by-step explanation:</u>

A) F(c) = 32 means that when c = 0 then F = 32

B) when c = 100°, then F = 212° can be written as: F(100) = 212°

C) \dfrac{F(100)-F(0)}{100-0}=\dfrac{212-32}{100}=\dfrac{180}{100}=1.8

   F(c) = 1.8c + 32

 F(25) = 1.8(25) + 32

           =   45  +   32

           =         77°

Solve for x! Please help!
erica [24]

Answer:

<h2>x = 12</h2>

Step-by-step explanation:

ΔADC and ΔCDB are similar (AA). Therefore the sides are in proportion:

\dfrac{AD}{DC}=\dfrac{DC}{DB}

We have AD = 16, DC = x, DB = 9. Substitute:

\dfrac{16}{x}=\dfrac{x}{9}            <em>cross multiply</em>

x^2=(16)(9)\to x=\sqrt{(16)(9)}\\\\x=\sqrt{16}\cdot\sqrt9\\\\x=4\cdot3\\\\x=12

Si tenemos un rectángulo en el que su base es igual a x+10 y su altura es igual a x+9, ¿cuál será la expresión algebraica correc
aksik [14]

Responder:

x² + 19x + 90

Explicación paso a paso:

Área del rectángulo = Base * Alto

Dado

Base = x + 10

Altura = x + 9

Área del rectángulo = (x + 10) (x + 9)

Área del rectángulo = x (x) + 9x + 10x + 9 (10)

Área del rectángulo = x² + 9x + 10x + 90

Área del rectángulo = x² + 19x + 90

La expresión que representa el área si la cifra es x² + 19x + 90

19. The cost function of a product is C(Q) = 3Q² +8 and the demand function of the same product is P =1/3 Q² — 10Q + 105, where
Kamila [148]

The marginal revenue at the output level 4 is 24, marginal revenue at the output level 4 is 41, and marginal profit at the output level 4 is 17.

<h3>What is a marginal cost?</h3>

It is defined as the cost showing an increase in the cost when the number of units produced increases, In simple words it is the ratio of the cost to quantity.

We have a cost function of a product:

C(Q) = 3Q² +8

a) To find the marginal cost to differentiate it with respect to Q and plug

Q = 4:

C'(Q) = 6Q

C'(4) = 6(4) = 24

b) R(Q) = P×Q

\rm R(Q) = (\dfrac{1}{3} Q^2 - 10Q + 105)Q

\rm R(Q) = \dfrac{1}{3} Q^3 - 10Q^2 + 105Q

R'(Q) = Q² - 20Q + 105

Plug Q = 4

R'(Q) = (4)² - 20(4) + 105

R'(Q) = 41

c) Marginal profit:

MP(Q)  = R(Q) - C(Q)

After calculating:

\rm MP(Q)  = \dfrac{1}{3}Q^3-13Q^2+105Q-8

MP'(Q) = Q² - 26Q + 105

Plug Q = 4

MP'(Q) = 16 - 104 + 105 = 17

Similar, we can find the maximum profit.

Thus, the marginal revenue at the output level 4 is 24, marginal revenue at the output level 4 is 41, and marginal profit at the output level 4 is 17.
