Answer:

no solutions

Step-by-step explanation:

y = 2x → (1)

y = 2x - 3 → (2)

since both equations express y in terms of . equate the right sides to find any solutions.

2x - 3 = 2x ( add 3 to both sides )

A $1000 cash inflows at the end of each year would have a future value of $8,142.01, $8,922.80 and $11.772012 at the end of the year 7 for interest rates of 5% , 8% and 17% respectively.

Annuities are a financial instrument that generates a regular stream of cash. They have both a present and future value dependent upon the value of the cash payment, the number of payment periods and the interest rate. This question does not specify the cash inflow amount so an answer will be generated that can be scaled on multiples of $1000.

Let C represent the cash inflow at the end of each year. The future value (FV) of this cash inflow is given by:

FV = [tex]C[((1+i)^n-1)/i][/tex]

where i is the annual interest rate and n is the number of years.

(a) For i = 5% and n = 7

FV = [tex]C [((1+0.05)^7-1)/0.05][/tex]

FV= C[(1.047100-1)/0.05]

FV = C [8.142008]

(b) For i = 8% and n = 7

FV = [tex]C [((1+0.08)^7-1)/0.08][/tex]

FV = C[(1.713824 - 1)/0.08]

FV = C[8.922803]

(c) For i = 17% and n = 7

FV = [tex]C [((1+0.17)^7-1)/0.17][/tex]

FV = C[(3.001242 - 1)/ 0.17]

FV = C[11.772012]

Therefore, A $1000 cash inflows at the end of each year would have a future value of $8,142.01, $8,922.80 and $11.772012 at the end of the year 7 for interest rates of 5% , 8% and 17% respectively.

The value of angles are,

∠ H = 20°

∠ G  = 100°

∠ I = 60°

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

Given that;

Two triangles are similar.

Now, We have in triangle XYZ,

∠Y = 20°

∠Z = 100°

Hence, ∠ X = 180 - (100 + 20)

∠ X = 60°

Thus, By definition of similarity;

∠ H = ∠ Y = 20°

∠ G = ∠ Z = 100°

∠ X = ∠ I = 60°

Thus, The value of angles are,

The measure of m∠H in the triangle is 85°.

Similar triangles are two triangles that have the same shape but can have different sizes. More specifically, two triangles are similar if their corresponding angles are congruent and their corresponding sides are proportional.

Since ΔABC and ΔFGH are similar, we can say:

m∠A =  m∠F

m∠B =  m∠G

m∠C =  m∠H

m∠A  +  m∠B +  m∠C = 180° (sum of angles in a triangle)

We have m∠A = 50° and m∠B = 45°

50°  +  45°  +  m∠C = 180°

m∠C = 180° - 50° - 45°

m∠C = 85°

Since m∠C =  m∠H

Thus, m∠H =  85°

The two functions are inverses of each other.

Case 2

f ° g (x) = x, g ° f (x) = x

The two functions are inverses of each other.

In this problem we need to determine the composition between two functions and determine if both functions are inverses of each other. A composition is defined below:

f ° g (x) = f [g (x)]

Where the independent variable of the function f(x) is substituted by function g(x). Two functions are inverses if and only if the following condition is fulfilled:

f[g (x)] = g[f (x)]

Now we proceed to determine the compositions and relationships for each case:

Case 1

f(x) = 3 · x

g(x) = x / 3

f ° g (x) = 3 · (x / 3)

f ° g (x) = x

g ° f (x) = (3 · x) / 3

g ° f (x) = x

Functions f(x) and g(x) are inverses of each other.

Case 2

f(x) = (x - 3) / 2

g(x) = 2 · x + 3

f ° g (x) = [(2 · x + 3) - 3] / 2

f ° g (x) = 2 · x / 2

f ° g (x) = x

g ° f (x) = 2 · [(x - 3) / 2] + 3

g ° f (x) = (x - 3) + 3

CI = P(1+r/100)ⁿ

P = principal amount, CI =  compound interest, r = rate, n = time

Therefore,

CI = 6050(1+r/100)²....(i)

CI = 6655(1+r/100)³....(ii)

Diving eq(ii) by eq(i)

6655 / 6050  = (1+r/100)
