The value of a baseball​ player's rookie card began to increase once the player retired. When he retired in 1997 his card was worth ​$6.36. The value has increased by ​$1.93 each year since then. Express the relationship relating the value of the card y in dollars and the number of years x the player has been in retirement with an equation. Is the relationship between x and y​ proportional? What was the value of the card in 2007
​?

Answers

Part a: The relationship between x and y can be represented as y = 6.36 + 1.93x

Part b: The relationship between x and y is proportional

Part c: The value of the card in 2007 will be $25.66

Worth of the card in 1997 = $6.36

Increase in value each year = $1.93

Let x be the number of years the player has been in retirement and y be the value of the cards in dollars

Formulating the equations we get the following:

Value of the card = Worth of the card in 1997 + Increase in value each year*Number of years the player has been in retirement

Part a:

y = 6.36 + 1.93x

Part b:

The relationship between x and y is proportional as the increase in the value each year leads to an increase in the worth of the card

Part c:

Value of the card in 2007:

The number of years the player has been retired will be 10 years in this case

Formulating the equation we get the following:

y = 6.36 + 1.93(10)

= 25.66

So, the value will be $25.66

Explain how knowing the linear factor establishes that f(10) multiple of 12.

Answers

f(10) is a multiple of 12 because f(x) has a linear factor of x+2 and x+2 = 12, when x = 10

f(10) multiple of 12 is given as:

The first-degree equations that make up a polynomial's linear factors serve as the foundation stone for higher-order and more complicated polynomials. The formula for a linear factor is ax + b, and it cannot be factored further. When paired with other linear factors, each linear factor represents a separate line, resulting in several sorts of functions with progressively more intricate graphical representations.

f(10) = (10+2)(100+20+2)

A square has an area of 144 ft^2 what is the length of each side

Squaring a number means you multiply it with itself.

The square root goes in reverse to have [tex]\sqrt{144} = 12[/tex]

Answer:

Each side is 12 ft long.

Step-by-step explanation:

So, you have a square, which means all of the sides are going to be the same length. So, you need something times itself that equals 144. Or, you need the square root of 144 (Because when something is squared, it is multiplied by itself). And the square root of 144 is 12.

The linear function that passes through the points (-3, 18) and (2, -7) is defined by the rule:

y = -5*x + 3

How to find the linear function?

We can find a general linear function in the slope-intercept form as:

y = m*x + k

Where m is the slope and k is the intercept of the y-axis.

If we know that the line passes through the points (a, b) and (c, d) then the slope of the function is:

m = (d - b)/(c - a)

In this case the line passes through the points (-3, 18) and (2, -7), then the slope is:

m = (-7 - 18)/(2 + 3) = -5

So the line is something like:

y = -5*x + k

To find the value of k, we can use one of the two given points, I will use (2, -7), so we get:

-7 = -5*2 + k

-7 = -10 + k

-7 + 10 = k

3 = k

So the linear function is:

y = -5*x + 3

Keandre wants to buy a new pair of shoes that costs $220. In order to earn money for this, Keandre babysits his neighbor for $10 an hour. He also has saved up his monthly allowance which totals $50. What is the minimum number of hours he should babysit in order to be able to afford the shoes?

Answers

Answer:

Step-by-step explanation:

$220=$10x+$50

x= hours

subtract $50 from both sides making sure to cancel the right side

$220-$50=$10x

$170=$10x

Divide both sides by $10 to leaving x by itself on the right side

$170/$10=x

17hrs=x

The minimum number of hours is 17 hours to babysit in order to be able to afford the shoes.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Cost of new pair of shoes = $220

In order to earn money for this, Keandre babysits his neighbor for $10 an hour.

And, He also has saved up his monthly allowance which totals $50.

Now,

Let number of minimum hours = x hour

So, We can formulate;

⇒ $10x + $50 = $220

Solve for x as;

⇒ $10x + $50 = $220

Subtract 50 both side, we get;

⇒ $10x + $50 - $50 = $220 - $50

⇒ $10x = $170

Divide by 10 both side, we get;

⇒x = 17

Thus, The minimum number of hours is 17 hours to babysit in order to be able to afford the shoes.

Answers

To solve the question, we will follow the steps below:

[tex]f(x)=x^2-1[/tex]

To find f(f(x)), we will simply replace x by x² - 1 in the function x² - 1

That is:

f((fx)) = (x²-1)² - 1

Then we open the parenthesis

f(f(x)) = (x² - 1)(x² -1) - 1

=x²(x²-1)-1(x²-1) - 1

= x⁴ - x² - x² + 1 - 1

= x⁴ - 2x²

The apartment you want has a monthly rent of $585. What does your gross monthly income range need to be for you to be able to rent this apartment? Maximum spent on rent should be 25% - 35% of your gross monthly income

Answers

The gross monthly income range to be for you to be able to rent this apartment is $1671 - $2340.

How to calculate the value?

Let the monthly income be x.

Therefore, 25% of x = 585

0.25x = 585

Divide

x = 585/0.25

x = $2340

The maximum income is $2340.

The minimum income will be:

35% of x = 585

0.35x = 585

Divide.

x = 585 / 0.35

x = $1671

In this case, the minimum value is $1671 and the maximum value is $2340. This illustrates the concept for finding the range.

The range is $1671 - $2340.

O8 inches

Answers

The length of the diagonal of the napkin is 11 inches.

Here, we are given that a square napkin has a side of length 8 inches.

All the sides of a square are equal and the measure of angle formed by any two adjacent sides is also equal and 90°.

Thus, by using Pythagoras theorem, we can form the following equation-

[tex]side^{2} + side^{2} = diagonal^{2}[/tex]

Let the diagonal of the square be d. Then, we have-

[tex]8^{2} +8^{2} =d^{2}[/tex]

64 + 64 = [tex]d^{2}[/tex]

128 = [tex]d^{2}[/tex]

[tex]d^{2}[/tex] = 128

d = [tex]\sqrt{128}[/tex]

d = [tex]8\sqrt{2}[/tex]

the value of [tex]\sqrt{2}[/tex] is approximately 1.41. Thus,

d = 8 × 1.41

Thus, the length of the diagonal of the napkin to the nearest inch comes out to be 11.

The drama club is selling tickets to its play. An adult ticket costs $15 and a student ticket costs $11. The auditorium will seat 300 ticket-holders. The drama club wants to collect at least $3630 from ticket sales.


a. Write and graph a system of four inequalities that describe how many of each type of ticket the club must sell to meet its goal.



b. List three different combinations of tickets sold that satisfy the inequalities.

Answers

The system of inequalities is x + y ≤ 300, 11x + 15y ≥ 3630, x ≥ 0 and y ≥ 0 while the three points are (70, 200), (150, 140) and (140, 150)

How to graph the system

From the question, we have the following parameters that can be used to determine system of inequalities

An adult ticket = $15Student ticket = $11. Auditorium capacity = 300 ticket-holdersAmount from sales = at least $3630 from ticket sales.

Represent the adult with y and the students with x

So, we have the following representations

x + y ≤ 300 ---- the ticket holders cannot exceed the capacity

11x + 15y ≥ 3630 --- the total sales cannot be less than $3630

x ≥ 0 -- the number of students cannot be negative

y ≥ 0 -- the number of students cannot be negative

Write out the inequalities

x + y ≤ 300

11x + 15y ≥ 3630

x ≥ 0

y ≥ 0

Next, we represent the inequalities on a graph

See attachment for the graph of the inequalities

Explanation

Given the expression

cos(2x)=cos(x)

In trigonometry expression;

cos2x = 2xos^2x - 1

Substituting into the equation given;

cos(2x)=cos(x)

2xos^2x - 1 = cos x

Rearrange

2xos^2x - 1 - cosx - 1 = 0

Let P = cosx

2P^2 - P - 1 = 0

Factorize

2P^2 - 2P+P-1 = 0

2P(P-1)+1(P-1) = 0

2P+1 = 0 and P-1 = 0

P = -1/2 and 1

Recall that P = cosx

-1/2 = cosx

x = cos^-1(-1/2)

x = 120 degrees = 2pi/3

If P = 1

cosx = 1

x = cos^-1(1)

x = 0

Hence the value of x that satisfies the equation is 0 ad 2pi/3
