Givenf(x)=4x^2 - 1, and g(x) = 2x - 1, find g(f(2)).
Given f(x) = x^2 and g(x)=x - 1, write each composite function.State the domain of each:2.f(g(x)) 3.g(f(x))

Answers

The value of the function g(f(2)) is 29 and 2.f(g(x)) is (x - 1)(2x - 2).

What is a composite function?

When the output of one function is given to the input of another function they are called composite functions.In (fog)x which is [f{g(x)}] here the out of the function g(x) is the input of the function f(x).

Given, f(x) = 4x² - 1. and g(x) = 2x - 1.

Now, g(f(2)) is the output of f(2) is the input of g(x).

∴ f(2) = 4(2)² - 1.

f(2) = 15.

Now, g(f(2)) = 2(15) - 1.

g(f(2)) = 29.

Also given,

f(x) = x² and g(x) = x - 1.

Now, 2.f(g(x)).

2.f(g(x)) = 2.f(x- 1).

2.f(g(x)) = 2(x - 1)².

2.f(g(x)) = 2(x² - 2x + 1).

2.f(g(x)) = 2x² - 4x + 2.

2.f(g(x)) = 2x² - 2x - 2x + 2.

2.f(g(x)) = 2x(x - 1) - 2(x - 1).

2.f(g(x)) = (x - 1)(2x - 2).

There is no restriction to the domain of this quadratic function.

Answers

The sample space S for the net amount you win (after deducting the cost of pay) is S = {-$2, $1, $4, $7}.

What is cost?

A cost is the worth of money that has been expended in the production or delivery of a good or service and is therefore no longer accessible for use in accounting, retail, research, or accounting. In business, the cost may be one of acquisition, in which case the cost is the sum of the money used to obtain it.

Let, a game consists of drawing three cards at random from a deck of playing cards.

You win $3 for each red card that is drawn.

It costs $2 to play.

After deducting the cost of pay the amount will start from -$2.

For first red card drawn you win $3.

So, the amount becomes, -$2 + $3 = $1.

For second red card drawn you again win $3.

So, the next amount becomes $1 + $3 = $4.

For third red card drawn the amount becomes,

$4 + $3 = $7.

Hence, the sample space S for the net amount you win is

S = {-$2, $1, $4, $7}.

The minimum monthly payment for Brian's credit card is 3.5% of his balance or $25, whichever is higher. If Brian's balance at the end of his last billing cycle was $722, what is his minimum monthly payment?

Answers

The minimum monthly payment for Brian is $25.

How to find the minimum payment?

The minimum payment is the smallest amount of money you must pay each month to maintain the status of your account. The statement balance is your total account balance for that billing cycle. The current balance is the sum of your most recent bill plus any charges.

From the information, the minimum monthly payment for Brian's credit card is 3.5% of his balance or $25

Since the balance was $722, the amount will be:

= 3.5% × $722

= 0.035 × $722

= $25.27

Since $25.27 is more than $25, the minimum monthly payment is $25.

Answers

The number of runs up and runs down for the preceding data is 5.

What is runs up ?

Runs up refers to the number of observations that are higher than the number of observations before them.

What is runs down ?

Runs down refers to the number of observations that are lower than the number of observations before them.

As 2nd observation is higher than 1st observation, 4th observation is higher than 3rd observation and 6th observation is also higher than 5th observation so 2nd, 4th,6th observation should be included in runs up.

Therefore,

Runs up = 2nd + 4th + 6th observations

             = 3

As 3rd observation is lower than 2nd observation,5th observation is also lower than 4th observation so 3rd,5th observation should be included in the runs down

Therefore,

Runs down= 3rd +5th observations

The football field is longer than soccer field.

What is a expression? What is a mathematical equation? What is unit conversion?

A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions. Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem. Conversion of units is the conversion between different units of measurement for the same quantity, typically through multiplicative conversion factors.

We have a soccer field that is 105 meters long and a football field is 120 yards long.

In one yard, we have -

1 yard = 0.9144 meters

Then, in 120 yards, we will have -

120 x 0.9144 = 109.728 meters

Now, 109.728 meters > 105 meters.

The formula for the line passing through the intersection of (3, 2) and A B (5 , 6) equals y = 2x - 4

What is slope?

A line's steepness and direction are measured by the line's slope. Without actually using a compass, determining the slope of lines in a coordinate plane can assist in forecasting whether the lines are parallel, perpendicular, or none at all.

Any two different points on a line can be used to calculate the slope of any line.

The ratio of "vertical change" to "horizontal change" between two different points on a line is calculated using the slope of a line formula.

We will comprehend the slope-finding method and its applications in this article

According to our question-

Let A be the initial point ( 3 , 2 )

Let B be the second point ( 5 , 6 )

A ( x₁ , y₁ ) = A ( 3 , 2 ) ( 3 , 2 )

B ( x₂ , y₂ ) = B ( 5 , 6 ) ( 5 , 6 )

The slope of the line is now determined by,

Slope m is equal to (y2 - y1) / (x2 - x1)

By changing the values, we obtain

Slope m is equal to (6 - 2)/(5 - 3)

= 4 / 2

= 2

Slope of the line therefore equals 2.

The equation for the line is now y - y1 = m (x - x1).

By changing the values, we obtain

y - 2 = 2 ( x - 3 ) ( x - 3 )

y - 2 = 2x - 6

2 is added to both sides of the equation to get

y = 2x - 4

HENCE, The formula for the line passing through the intersection of (3, 2) and A B (5 , 6) equals y = 2x - 4.

2. Write two equivalent expressions to represent the perimeter of this rectangle.


(pls add an explanation)

Answers

The perimeter of a rectangle is 2x+6 units and the area of a rectangle is 5x-10 square units.

Given that, the breadth of a rectangle =5 units and the length of a rectangle =(x-2) units.

What is the perimeter of a rectangle?

The perimeter of a rectangle is the total distance of its outer boundary. It is twice the sum of its length and width and it is calculated with the help of the formula: Perimeter = 2(length + width).

Here, perimeter =2(x-2+5)

= 2(x+3)

= 2x+6 units

Area of a rectangle =length × width

= (x-2) × 5

= 5x-10 square units

Therefore, the perimeter of a rectangle is 2x+6 units and the area of a rectangle is 5x-10 square units.

Answers

A possible first step Vivi could take is multiply each term in the second equation by 2 and she can also multiply each term in the second equation by 4. The correct option is d. Both a and c could work.

Elimination method: Determining a possible first step

From the question, we are to determine the statement that correctly describes a possible first step Vivi could take

From the given information,

The given system of equations is

4x + 6y = -14

-x + 3y = -10

To eliminate y, we can multiply each term in the second equation by 2 and then subtract

2 × [-x + 3y = -10

-2x + 6y = -20

Then, subtract

4x + 6y = -14

-{ -2x + 6y = -20

------------------------

6x = 6

To eliminate x, we can multiply each term in the second equation by 4 and add the equations,

4 × [-x + 3y = -10

-4x + 12y = -40

Then, add

4x + 6y = -14

+{ -4x + 12y = -40

--------------------

18y = -54

Hence, we can multiply each term in the second equation by 2 and we can also multiply each term in the second equation by 4.

A boat travels about 6 kilometers per hour in still water. If the boat is on a river that flows at a constant speed of
kilometers per hour, it can travel at a speed of (6+r) kilometers per hour downstream. On one particular river, a
boat travels 12 kilometers down stream. The amount of time it takes the boat travel depends on the speed of river
and is expressed by the equation t(r) =
12
(6+r)
The graph is shown below.
What does t(3) mean in this situation?
At what value of r does the graph have a vertical asymptote? Explain
how you know and what this asymptote means in this situation.

Answers

The numeric value t(3) represents the time that it takes for the boat to cross the river when the velocity of the river is of 3 kilometers per hour.The vertical asymptote of the function is at t = -6, as the denominator of the function would be of zero.

What is modeled by the function?

The function in the context of this problem is modeled as follows:

t(r) = 12/(6 + r)

In which the input and output of the function are given, respectively, by:

r is the velocity of the river.t(r) is the time it takes to cross the river considering the given velocity.

Then the numeric value at t = 3 represents the time in hours it takes for the boat to cross the river when the velocity of the river is of 3 kilometers per hour.

What is the vertical asymptote of the function?

The vertical asymptote of a function are the values of the input for which the function is not defined.

A fraction is not defined at the zeros of the denominator, hence:

t + 6 = 0

t = -6 is the vertical asymptote of the function.
