If given a function, to evaluate the function for a given value of x, input the value of x in the equation and solve to evaluate the function.

Given the function, f(x) = -3(4x² + 12) + 3/4(8x) - 2x, to find the value of f(1/2), substitute x = 1/2 into the equation:

g(x) is a dilation of scale factor 1/2 of f(x), and the rule is:

g(x) = 2x + 3

Here we have the function f(x) = 4x + 6 and the function g(x) that is defined as:

g(x) = (1/2)*f(x)

So g(x) is a vertical dilation of scale factor k = 1/2 of f(x).

Replacing f(x) in there we get:

g(x) = (1/2)*(4x + 6) = (4/2)*x + 6/2 = 2x + 3

Answer:

[tex]y = \dfrac{2}{3}x + \dfrac{16}{3}}[/tex]

Step-by-step explanation:

The genera slope-intercept equation of a line is

y = mx + 8 where m is the slope and b the y-interecept

A perpendicular line will have a slope = -1/m ie the negative of reciprocal of the first line such that m x (-1/m ) = -1

The equation of the tangent line is

3x + 2y = 28.

1. Convert to slope-intercept form:

So slope = -3/2

Reciprocal of -3/2 = -2/3
Negative of reciprocal = +2/3

Slope of a perpendicular line should be -1/3 and the resultant equation of the line(the support arm) should be:

y = (2/3)x + b

To calculate b for the complete line equation plug in the point B(4, 8) and solve for B

y = 8 when x = 4

=> 8 = (2/3)(4) + b

Switch sides: (does not change any signs)
8/3 + b = 8

Subtract  8/3 on both sides
b =  8 - 8/3

b = 24/3 -  8/3

b = 16/3

So equation of the support arm is

[tex]\boxed{y = \dfrac{2}{3}x + \dfrac{16}{3}}[/tex]

The given quadrilateral RSTV is a kite.

The following characteristics apply to quadrilaterals, which are polygons.

To classify the quadrilateral calculate the length of its sides using the distance formula given as follows:

[tex]\sqrt{(x_{2} - x_{1})^{2} + (y_{2} - y_{1})^{2} }[/tex]

In the given quadrilateral RSTV,

RS = [tex]\sqrt{(2 - (-5))^{2} + (6 - 7)^{2} }[/tex] = [tex]\sqrt{50 }[/tex]

RV = [tex]\sqrt{(-4 - (-5))^{2} + (0- 7)^{2} }[/tex] = [tex]\sqrt{50}[/tex]

ST = [tex]\sqrt{(5 - 2)^{2} + (-3- 6)^{2} } = \sqrt{90}[/tex]

VT = [tex]\sqrt{(-3 - 0)^{2} + (5- (-4))^{2} } = \sqrt{90}[/tex]

The two adjacent sides of the quadrilateral are equal i.e. RS = RV and ST = VT.

A kite is a quadrilateral with two pairs of sides that are both the same length and are next to one another.

Using a system of equations, a possible set of values for a, b and c such that it results in an integer number is given by:

a = 6, b = 3, c = 2.

A system of equations is when multiple variables are related, and equations are built to find the numeric values of each variable, according to the relations built in the problem.

In the context of this problem, the variables are the given ones of:

a, b and c.

An integer number is a number that has no decimal part, hence the easiest way to solve this is making the sum of 1.

Attributing a = 6, we have that:

[tex]\frac{1}{6} + \frac{1}{b} + \frac{1}{c} = 1[/tex]

[tex]\frac{1}{b} + \frac{1}{c} = \frac{5}{6}[/tex]

This is possible with these two fractions:

[tex]\frac{1}{2} + \frac{1}{3} = \frac{3 + 2}{6} = \frac{5}{6}[/tex]

b = 2, c = 3.

The equation to determine the number of players the team can bring is $842.50 + $21.50y = $1,186.50

The team can bring 16 players to the tournament.

To go to a tournament, softball team members raised $1186.50 and rented a bus for $842.50, and the cost of meals of each player is $21.50.

Let y represent the number of players.

$842.50 + $21.50 × y = $1,186.50

$842.50 + $21.50 × y = $1,186.50

$842.50 + $21.50y = $1,186.50

Subtracting $842.50 from each side.

$21.50y =  $1,186.50 - $842.50

$21.50y =  $344

Divide both side of the equation by $21.50.

x = $344 / $21.50

x = 16 players

As a result, the team is allowed to enter 16 players into the competition.

Using proportions, the amounts are given as follows:

A proportion is a fraction of a total amount, and equations can be built to find the desired measures in the problem using operations such as multiplication or division.

One example of application is for percentage problems, as the equivalent amount can be found multiplying the equivalent decimal by the total amount.

The amount of Federal Income Tax Withholding each month is given by:

0.2 x 3500 = $700.

The amount of State Income Tax Withholding each month is given by:

0.12 x 3500 = $420.

The amount of Social Security Tax Withholding each month is given by:

0.0825 x 3500 = $288.75.

The amount contributed to the 401k each month is:

0.04 x 3500 = $140.

The take-home pay for the month is the $3,5500 subtracted by all the with holdings, hence:

3500 - (700 + 420 + 288.75 + 140) = $1,951.25.

The change that Grant received to the nearest cent after giving the delivery driver with a $100 bill is $ 32.6.

This is a question of percentages.

Given that:-

Price of bouquet of flowers = $ 55

Sales tax % = 6.5 %

Tip % = 15 %

Delivery fee= $10

We have to find the change that Grant received to the nearest cent after giving the delivery driver with a $100 bill.

Sales tax = (6.5/100)*55 = $3.575

$55 + $3.575 = $58.575

Tip = (15/100)*58.575 = $ 8.78625

Total money paid by Grant = 55 + 3.575 + 8.78625 = $ 67.36125 ≈ $ 67.4
