Given the following functions f(x)

Answers

Answer:    x

============================================

Work Shown:

[tex]g(x) = \frac{(x-1)^2}{3}\\\\g(f(x)) = \frac{(f(x)-1)^2}{3}\\\\g(f(x)) = \frac{(1+\sqrt{3x}-1)^2}{3}\\\\g(f(x)) = \frac{(\sqrt{3x})^2}{3}\\\\g(f(x)) = \frac{3x}{3}\\\\g(f(x)) = x\\\\[/tex]

The idea is to start with g(x) and then replace every x with f(x). From there you plug in f(x) = 1+sqrt(3x) and simplify.

For each sequence, find the first 4 terms and the 10th term.
A) n+5
B)2n-1

Answers

Answer:

see explanation

Step-by-step explanation:

(a)

To find the first 4 terms substitute n = 1, 2, 3, 4 into the n th term formula.

a₁ = 1 + 5 = 6

a₂ = 2 + 5 = 7

a₃ = 3 + 5 = 8

a₄ = 4 + 5 = 9

For the 10 th term substitute n = 10, that is

a₁₀ = 10 + 5 = 15

The first 4 terms are 6, 7, 8, 9 and the 10 th term is 15

(b)

Substitute n = 1, 2, 3, 4 and 10 into the n th term formula

a₁ = 2(1) - 1 = 2 - 1 = 1

a₂ = 2(2) - 1 = 4 - 1 = 3

a₃ = 2(3) - 1 = 6 - 1 = 5

a₄ = 2(4) - 1 = 8 - 1 = 7

a₁₀ = 2(10) - 1 = 20 - 1 = 19

The first 4 terms are 1, 3, 5, 7 and the 10 th term is 19

How can you tell if there will be more than one solution for the geometric means? Why does this happen with the geometric means?

Answers

Answer:

a. We can tell if there will be more than one solution for the geometric means if the set of numbers is an even number.

b. This happens because, there are two possible values for the nth root of a set of even numbers.

Step-by-step explanation:

a. How can you tell if there will be more than one solution for the geometric means?

We can tell if there will be more than one solution for the geometric means if the set of numbers is an even number.

Since geometric means of n numbers from x₁,x₂, x₃,...,xₙ is

GM = ⁿ√x₁,x₂, x₃,...,xₙ .

Now, if n is an even number, the geometric means would have both a positive and negative value.

For example, if n = 2,

GM = ±√x₁,x₂ which is

GM = +√x₁,x₂ or -√x₁,x₂.

b. Why does this happen with the geometric means?

This happens because, there are two possible values for the nth root of a set of even numbers. For example if n = 2,

GM = ±√x₁,x₂ which is

GM = +√x₁,x₂ or -√x₁,x₂.

So, we have two possible values for the geometric means.

Each year, votes are cast for the rookie of the year in a softball league. The voting results for the top three finishers are shown in the table below. How many points is a third-place vote worth?

Answers

Answer:

A third place vote is worth 1 point

Step-by-step explanation:

Let the number of points for a first place vote be x, number of points for a second place vote be y and the number of points for a third place vote be z.

So, by multiplying the number of points by the number of what the point is worth and adding all together, we shall have the total points;

Hence, we have the following equation systems;

23x + 5y + z = 131

5x + 17y + 4z = 80

x + 5y + 15z = 35

These are the three equations we need to solve simultaneously to get the value of z

From equation 3, x = 35 -5y -15z

Insert this into the first two equations;

23 ( 35 -5y -15z) + 5y + z = 131

5(35-5y-15z) + 17y + 4z = 80

805 - 115y -345z + 5y + z = 131

805-131 = 115y + 345z -5y - z

674 = 110y + 344z ••••••••••(*)

The second equation now becomes the following;

5(35-5y-15z) + 17y + 4z = 80

175 -25y -75z + 17y + 4z = 80

175-80 = 25y + 75z -17y -4z

95 = 8y + 71z

8y + 71z = 95 •••••••••••(**)

So we have to solve x and xx simultaneously;

110y + 344z = 674

8y + 71z = 95

110/8 = 13.75 , so multiply equation xx by 13.75 and equation x by 1

110y + 344z = 674

110y + 976.25z = 1306.25

Subtract equation xx from x

(976.25z - 344z) = (1306.25 -674)

632.25z = 632.25

z = 632.25/632.25

z = 1

Solve for x.
