Step-by-step explanation:

Answer:

\(k = \frac{1}{2}\)

Step-by-step explanation:

Given

x 2 4 6 8

y 1 2 3 4

Required

Determine the constant of proportionality (k)

The relationship between x and y is:

\(y = kx\)

When y = 1, x = 2;

So, we have:

\(1 = k * 2\)

\(2 * k = 1\)

Make k the subject

\(k = \frac{1}{2}\)

Hence, the constant of proportionality is 1/2

Answer:

\(\frac{1}{3}\)

Step-by-step explanation:

The rate of change is the change in y over the change in x. In this table, the change in y is +1, and the change in x is +3, so we get \(\frac{1}{3}\)

The futures price F0 must be equal to the present value of the expected future spot price, which is \(S0e^{(r-q)} T\). Hence, equation (5.3) is true.

We can use a similar strategy to Footnote 2 to show that equation (5.3) is correct.

Consider an investor who wants to invest in an asset with spot price S0, which pays a continuous dividend yield of q, and simultaneously take a short position in a futures contract with maturity T, which has a futures price of F0. The investor buys one unit of the asset for S0 and sells a futures contract for F0.

At maturity T, the futures contract will be settled at the spot price of the asset, ST. If ST > F0, the investor makes a profit of ST - F0 on the asset, but incurs a loss of F0 - ST on the futures contract. If ST < F0, the investor incurs a loss of F0 - ST on the asset, but makes a profit of ST - F0 on the futures contract.

Now, suppose that equation (5.3) does not hold, i.e., \(F0 \neq S0e^{(r-q)} T\). If \(F0 > S0e^{(r-q)} T\), then the investor can buy the asset for S0, sell a futures contract for F0, and invest the difference \((F0 - S0e^{(r-q)} T)\) at the risk-free rate r. At maturity T, the investor will receive ST from the asset, F0 from the futures contract, and \((F0 - S0e^{(r-q)} T)e^r(T-t)\) from the investment. The total cash inflow will be \(ST + F0 + (F0 - S0e^{(r-q)} T)e^r(T-t).\) But this is greater than the initial outflow of S0, which means that the investor can make a riskless profit, violating the no-arbitrage principle.

Similarly, if\(F0 < S0e^{(r-q)} T\), then the investor can short-sell the asset for S0, buy a futures contract for F0, and borrow the difference \((S0e^{(r-q)} T - F0)\) at the risk-free rate r. At maturity T, the investor will receive ST from the short sale, F0 from the futures contract, and \((S0e^{(r-q)} T - F0)e^r(T-t)\)from the borrowing. The total cash inflow will be \(ST + F0 + (S0e^{(r-q)} T - F0)e^r(T-t)\). But this is greater than the initial outflow of S0, which means that the investor can make a riskless profit, violating the no-arbitrage principle.

Therefore, to avoid arbitrage opportunities, The futures price F0 must be equal to the present value of the expected future spot price, which is \(S0e^{(r-q)} T\). Hence, equation (5.3) is true.

Answer:

$48.30

Step-by-step explanation:

the other answer's start is correct.

30% discount of $20 is 30/100*20 = $6

so, a shirt costs now only $14.

but sales tax is always calculated from the actual sales price. not from the original list price.

so, we need to calculate 15% of $14 (and not $20) as sales tax.

=> 15/100*14 = $2.10

a shirt now costs incl. sales tax $14 + $2.10 = $16.10

three shirts cost 3 * $16.10 = $48.30

Multiply 2x by 2x first.

then 2x by 3

and then repeat that step and you add like terms

then recieve your answer.

Answer:

4x^2 + 12x + 9

Step-by-step explanation:

Actually, you are to find (2x + 3)^2, which is "the square of 2x + 3."

2x + 3 is a binomial.  There is a formula for the square of a binomial:

(a + b)^2 = a^2 + 2ab + b^2

Following this pattern,

(2x + 3)^2 becomes:

[2x]^2 + 2[2x][3] + [3^2], or

g(x) is a function with 3 different parts

First, from when x= -3 is from -8 to -2, it is a line that goes across -3, also because  there is this symbol with the line under ≤ , it means the dot is closed and filled in becuase the function includes 8.  at -2 there is < with no line so the circle is open and unfilled because it is not included

2nd, There is a line at y=1, from -2 to 4,  Same rules apply for open or closed circles.  -2 is closed and 4 is open

3rd, There is another line at y=5 from 4 to 10 where 4 is closed and 10 is open

ACF is a 30º-60º-90º triangle because of the following:

1) Based on a theorem, in a 30°-60°-90° triangle the sides are in the ratio 1 : 2 : \(\sqrt{3}\)

1 → short leg

2 → hypotenuse

\(\sqrt{3}\) → long leg

Side length of the hexagon is the short leg of the triangle. It is 1.

r1 is the radius of the incircle in a regular hexagon. 2(r1) is the diameter of the incircle. It is also the hypotenuse of the right triangle. It is 2.

Using Pythagorean theorem.

\(a^2 + b^2 = c^2\)

\(1^2 + b^2 = 2^2\)

\(b^2 = 2^2 - 1^2\)

\(b^2 = 4 - 1\)

\(b^2 = 3\)

\(\sqrt{b^2} = \sqrt{3}\)

\(b = \sqrt{3}\)

The side lengths from least to greatest as follows:

IK < KL < IJ < IL < LJ

To order the side lengths IK, KL, IJ, IL, and LJ from least to greatest, we can analyze the given figure.

Since the figure is not drawn to scale, we cannot determine the exact lengths of the sides. However, we can make some observations based on the given angles.

Let's analyze the angles:

Angle L: Since angle L is marked as 47°, we know that side KL is the shortest side, as it is opposite to the smallest angle in a triangle.

Angle I: Since angle I is marked as 20°, we can infer that side IJ is longer than side IK, as it is opposite to a larger angle.

Angle LJ: Since angle LJ is marked as 89°, we can conclude that side LJ is the longest side, as it is opposite to the largest angle in the triangle.

Based on these observations, we can order the side lengths from least to greatest as follows:

IK < KL < IJ < IL < LJ

a) The distance from point P to the pole  is: 6.2 m

b) The height of the Pole is: 6.2 m

The triangle attached shows us the triangle formed as a result of the given word problem about angle of elevation and distance and height.

Now, we are given that:

The angle of elevation of the top of the pole =  45°

Angle of elevation of the top of the pole = 58°.

|PQ|= 10m

a) PR is distance from point P to the pole and using trigonometric ratios, gives us:

PR/sin 58 = 10/sin(180 - 58 - 45)

PR/sin 58 = 10/sin 77

PR = (10 * sin 58)/sin 77

PR = 8.7 m

b) P O can be calculated with trigonometric ratios as:

P O = PR * cos 45

P O = 8.7 * 0.7071

P O = 6.2 m

Now, the two sides of the isosceles triangle formed are equal and as such:

R O = P O

Thus, height of pole R O = 6.2 m
