Answer:
Explanation:
Block on the table m(A) = m1,
block on the cord m2,
the coefficient of static friction is k1=0.4,
the coefficient of kinetic friction is k2 =0.28
(a)
Block A:
T = F(fr) = k1 •N = k(s) • m1 •g,
Block B: T = m2•g.
k1 • m1 •g= m2•g,
m1 = m2/k(s) = m2/0.4.
(b)
Block A:
T = F(fr) = k2 •N = k2 • m1 •g,
Block B:
T = m2•g.
k2• m1 •g= m2•g,
m1 = m2/k2 = m2/0.28.
Answer:
Value of the bond = $862.013
Explanation:
The value of the bond is the present value of the future cash receipts expected from the bond. The value is equal to present values of interest payment and the redemption value (RV).
Value of Bond = PV of interest + PV of RV
The value of the bond can be worked out as follows:
Step 1
<em>Calculate the PV of Interest payment
</em>
Present value of the interest payment
PV = Interest payment × (1- (1+r)^(-n))/r
Interest payment = $40
PV = 40 × (1 - (1.05)^(-12×2)/0.05)
= 40 × 13.7986
= 551.945
Step 2
<em>PV of redemption Value
</em>
PV of RV = RV × (1+r)^(-n)
= 1000 × (1.05)^(-12×2)
= 310.067
Step 3
<em>Calculate Value of the bond </em>
= 551.94567 + 310.067
=862.01
Value of the bond = $862.013
Answer:
The price elasticity of demand for icecream is -0.75, that means that is inelastic.
Explanation:
Price elasticity of demand measures the porcentage of the change in the demand when there is a change in the price. If the change in porcentage of the demand is less than the pocentage of change in the price we talk about inelastic demand. An increase in the price of inelastic goods will result in bigger revenues, as the porcentage in the drop of sales is less than the porcentage of increase in the price.
The formula is: % in change demand/% in change of price
-3%/4= -0.75
The minus symbol indicates that when the price rises the demand decrease.

What is the article tho? U can take a picture of the article and send it here so I can try and help you
Demand and marginal revenue curves are downward-sloping for monopolistically competition firms because: a. product differentiation allows each firm some degree of monopoly power.
<h3>What is product differentiation?</h3>
Product differentiation can be defined as what makes a product to different from another product which is why some producer tend to include a unique features in their so as to make their product distinct from that of others.
A monopolistic competitive firms can tend to face a downward - sloping demand curve based on the fact that it help to differentiate their product from that of others competitors.
Therefore the correct option is A.

The complete question is:
Demand and marginal revenue curves are downward-sloping for monopolistically competition firms because...
a)product differentiation allows each firm some degree of monopoly power
b)there are a few large firms in the industry and they each act as a monopolist
c)mutual interdependence among all firms in the industry leads to collusion
d)each firm has to take the market price as given
