Answer:

C.-3 to -2

Step-by-step explanation:

From the picture attached, it can be seen that an extreme value, that is, a maximum of the polynomial is found between x = -3 and x = -2. In this extreme point, the polynomial has an approximate value of 4.5

A company has fixed monthly costs of $130,000 and production costs on its product of $32 per unit. The company sells its product

Svet_ta [14]

Answer:

The cost function is $C(x)=32x+130000$ .

The revenue function is $R(x)=66x$ .

The profit function is $P(x)=34x-130000$ .

Step-by-step explanation:

We have the following definitions:

The cost function is a mathematical formula that gives the total cost to produce a certain number of units. It consists of variable costs and fixed costs and is given by

$C(x)=(fixed \:cost)+x\cdot (variable \:cost)$

If $x$ units are sold and the price per unit is $p(x)$ , then the total revenue is

$R(x)=x\cdot p(x)$

and $R(x)$ is called the revenue function.

If $x$ units are sold, then the total profit is

$P(x)=R(x)-C(x)$

and $P(x)$ is called the profit function.

Applying the above definitions we get that:

We know that the company has fixed monthly costs of $130,000 and production costs on its product of $32 per unit.

Therefore,

The cost function is $C(x)=32x+130000$ .

We know that the company sells its product for $66 per unit.

Therefore,

The revenue function is $R(x)=66x$ .

The profit function is

$P(x)=R(x)-C(x)\\P(x)=66x-(32x+130000)\\P(x)=34x-130000$

) Luci Lulu opened a cookie store in the mall. She found that the relationship between the price of a cookie, p, and the number

lozanna [386]

Answer:

The maximum revenue Luci can make selling cookies in one day is $4,004,000.

Step-by-step explanation:

Given;

x = −2000 p + 4000 ..................... (1)

Revenue = xp

Revenue = (−2000 p + 4000)p =

Revenue = −2000p^2 + 4000p .................... (2)

The price at which Luci will the maximum profit can be calculated by finding the derivative of equation (2), equating to 0, and then solve for p as follows:

−4000p + 4000 = 0

4000 = 4000p

p = 4000 / 4000

p = 1

This implies that the price at which Luci will the maximum profit is $1.

Substituting p = 1 into equation (2) to obtain the maximum revenue Luci can make selling cookies in one day, we have:

Revenue = (−2000 * 1)^2 + (4000 * 1)

Revenue = −2000^2 + 4000

Revenue = 4,000,000 + 4000

Revenue = 4,004,000

Therefore, the maximum revenue Luci can make selling cookies in one day is $4,004,000.

Find the missing angles

Pavlova-9 [17]

Answer:

the missing angles are 47,° 77,° 56°

Step-by-step explanation:

(133)+(x+13)= 180° (angles on a straight line)

133+x+13= 180°

146+x= 180°

X= 180-146

X= 34°

FOR ANGLE A

2X+9= 2(34)+9= 68+9= 77°

FOR ANGLE C

X+13= 34+13= 47°

FOR ANGLE B

47+77+Y= 180 (SUM OF ANGLES IN A TRIANGLE)

124+Y= 180

Y= 180-124= 56°

Y= 56°

the missing angles are 47,° 77,° 56°
