Answer:
The cost per month is increasing at a rate $365.
Explanation:
Differentiation Formula
Given that,
A manufacturer of handcrafted wine racks has determined that the cost to produce x units per month is given by
.
Again given that,
the rate of changing production is 13 unit per month
i.e 
To find the cost per month, we need to find out the value
when production is changing at the rate 13 units per month and the production is 70 units.

Differentiating with respect to t




Plugging 


[ plugging x=70]
=364
[ The unit of c is not given. Assume that the unit of c is dollar.]
The cost per month is increasing at a rate $365.
Answer:
WACC = 9.1%
Explanation:
The weighted Average cost of Capital(WACC) is the average cost of capital for the different sources of long-term capital available to a firm weighted according to the proportion each source of finance bears to the total capital in the pool.
cost of equity = Rf+ β×(Rm-Rf)
(Rm-Rf)= 6%, Rf- 4%, β- 1.4
=4% + (1.4×6%) = 12.4
Cost of preferred share = Dividend/price
= 3/25× 100= 12.0%
After tax cost of debt = Yield × (1-Tax rate) = 8.5%× (1-0.35)=5.53%
Type cost Market value Cost × Market Value
Equity 12.4% 7 0.868
Preferred 12% 4 0.48
Bond 5.53% <u>10 </u> <u> 0.553</u>
Total 21 1.901
WACC = 1.901
/21 × 100 =9.1%
WACC = 9.1%
From the information regarding the capacitor, when the plates are pulled away from each other, the amount of the charge decreases.
<h3>What is a capacitor?</h3>
A capacitor simply means a device that's used for storing electrical energy in a field.
In this case, when plates are pulled away from each other, increasing their separation, the the amount of the charge decreases.
