Answer: 18 quarters & 15 pennies

Step-by-step explanation:Q + p = 33

0.25q + 0.01p = 4.65

p = 33 - q

0.25 q + 0.01 (33 - q) = 4.65

q = (4.65 - 0.33)/(0.24)

q = 18

p = 33 - 18 = 15

Solve for a r=x(a+b)<br><br><br> Solve for x x/2=-7
Anastaziya [24]

Answer:

a = (r/x) -b

x = -14

Step-by-step explanation:

r=x(a+b)

Divide each side by x

r/x = a+b

Subtract b

r/x  -b = a

x/2=-7

Multiply each side by 2

x/2*2 = -7*2

x = -14

Find the cost function for the marginal cost function. C(x) =0.06 e 0.08x; fixed cost is $10 C(x)=_______
sashaice [31]

Answer:

The cost function for C(x) = 0.06\cdot e^{0.08\cdot x} is c(x) = 0.75\cdot e^{0.08\cdot x}+10.

Step-by-step explanation:

The marginal cost function (C(x)) is the derivative of the cost function (c(x)), then, we should integrate the marginal cost function to find the resulting expression. That is:

c(x) = \int {C(x)} \, dx + C_{f}

Where:

C_{f} - Fixed costs, measured in US dollars.

If we know that C(x) = 0.06\cdot e^{0.08\cdot x} and C_{f} = \$\,10, then:

c(x) = 0.06\int {e^{0.08\cdot x}} \, dx + 10

c(x) = 0.75\cdot e^{0.08\cdot x}+10

The cost function for C(x) = 0.06\cdot e^{0.08\cdot x} is c(x) = 0.75\cdot e^{0.08\cdot x}+10.
