In order to determine the relationship between the time and the amount of money in the account, we would calculate the average rate of change.

The average rate of change can be defined as a type of function that describes the average rate at which a quantity decreases or increases with respect to another quantity.

Mathematically, the slope (average rate of change) can be calculated by using this formula;

[tex]Slope = \frac{Change\;in\;y\;axis}{Change\;in\;x\;axis}\\\\Slope = \frac{y_2\;-\;y_1}{x_2\;-\;x_1}[/tex]

For Tammy's account, we have:

Points (x, y) = (6, 467) (8, 557)

Average rate of change = (557 - 467)/(8 - 6)

Average rate of change = 90/2

Average rate of change = 45.

As time increases, the amount of money in Tammy's account increases. Also, the rate at which the amount of money in the account is increasing is 45 dollars per month.

First of all, we would determine the increment in 6 months as follows:

Increment = $45 × 6

Increment = $270.

Initial amount = $467 - $270

Initial amount of money = $197.

Step-by-step explanation:

Line segments are congruent if they have the same length.

∠ ACB ≅ ∠ ABC

Segments of the same length are said to be congruent. Collinear points are those that share a line. A mathematical assertion that can be validated is known as a theorem. A point that separates a segment into two congruent segments is the segment's midpoint.

Line sections are harmonious assuming that they have a similar length. You can utilize tick imprints to demonstrate harmonious line sections. In the triangle underneath, line fragments Stomach muscle and BC are harmonious.

Harmonious portions are sections that have a similar length. ≅ Focuses that lie on a similar line are called collinear. A hypothesis is a numerical explanation that can be demonstrated. The midpoint of a section is a point that separates the portion into two harmonious fragments.

Therefore, ∠ ACB ≅ ∠ ABC

   The equation that defines the parabola with vertex at the origin and directrix at x = -5/2 is

x = y²/10

We define what a parabola is

 The parabola is a geometric shape that is formed from the intersection of a vertical plane in a cone.

The canonical equation of a parabola is given by

(x - h)² = 4p(y - k)

The parabola is a quadratic function, it is composed of a vertex, or inflection point, a focus and a directrix.

Since the vertex and the focal axis are on the same axis, we analyze that:

v = (0, 0)

d = (-2.5, 0) them the focus is on the right so the parabola is of the form X = Y².

(y - 0)² = 4p(x - 0)

If the directrix is x = -5/2 then the focus will be:

f = (0 + p, 0)

0 + p = 2.5

p = 0 + 2.5

p= 2.5

(y - 0)² = 4*2.5(x - 0)

(Y)² = 10(X)

x = y²/10

Using the given information, the equation of the circle with center located at point (1 , -2) and passes through the point (0 , 1) is (x - 1)^2 + (y + 2)^2 = 10.

Using the distance formula, get the radius of the circle by solving for the distance between the center (1 , -2) and the point (0 , 1).

radius = distance = √(x2 - x1)^2 + (y2 - y1)^2

radius = √(0 - 1)^2 + (1 - -2)^2

radius= √1 + 9

radius = √10

The standard form of the equation of the circle is given by (x - h)^2 + (y - k)^2 = r^2, where (h , k) is the location of the center and r is the radius of the circle.

Given the radius and center of the circle, substitute these values to the standard form of the equation of the circle.

(x - h)^2 + (y - k)^2 = r^2

where (h , k) = (1 , -2)

r = √10

(x - 1)^2 + (y - -2)^2 = (√10)^2

By elimination, the solution of the system of equations, r + 3s = 7 and 2r - s = 7, is (r , s) = (4 , 1).

A system of equations is a set of two or more equations which includes common variables. To solve system of equations, we must find the value of the unknown variables used in the equations that must satisfy all the equations.

There are three methods that can be used to solve system of equations.

1. Elimination

2. Substitution

3. Graphing

Using the elimination method, given two equations in r and s, a variable should be eliminated by adding/subtracting the two equations.

First, multiply the first equation by 2.

r + 3s = 7 ⇒ 2r + 6s = 14     (equation 1)

Subtracting the two equations will eliminate the variable r.

2r + 6s = 14     (equation 1)

2r  -   s = 7     (equation 2)

    7s    = 7

s = 1

Substitute the value of s to any of the two equations and solve for r.

2r - s = 7     (equation 2)

2r - 1 = 7

2r = 7 + 1

2r = 8

r = 4

Hence, the solution of the system of equations is (r , s) = (4 , 1).

By solving a linear equation, we can see that after 3 hours Ricardo has $61.91

We know that Ricardo has $132.16, and he rents a jet sky that costs $20 plus $16.75 per hour.

So, the cost of renting the jet sky for x hours is given by the linear equation:

C(x) = $20 + x*$16.75

The cost of renting this for 3 hours is:

C(3) = $20 + 3*$16.75 = $70.25

Subtracting this from what Ricardo had:

$132.16 - $70.25 = $61.91

A specific, verifiable prediction of what the researcher(s) believe the study's results will be is known as a hypothesis (plural: hypothese). It is stated at the outset of the investigation.

Most often, this entails speculating on a potential correlation between two variables: the independent variable (what the researcher modifies) and the dependent variable (what the research measures).

The initial amount and rate of change given a table for a linear function are $332 and $22.5, respectively

The table of linear function represents the given parameter

On the table, we have the following points

(x, y) = (6, 467) and (10, 647)

The rate of change is calculated as

Rate = (y2 - y1)/(x2 - x1)

So, we have

Rate = (647 - 467)/(10 - 2)

Evaluate

Rate = 22.5

This means that the rate of change is $22.5

The initial amount is calculated as

y = m(x - x1) + y1

Where

m = 22.5

So, we have

y = 22.5(x - x1) + y1

Using one of the points, we have

y = 22.5(x - 6) + 467

Set x = 0

So, we have

y = 22.5(0 - 6) + 467

Evaluate

y = 332

The simplification by combining like terms of 4t-(t + 3t)  is 0.

According to the given question.

We have an expression 4t - (t+3t).

As we know that, like terms are terms whose variables (and their exponents such as the 2 in x2) are the same.  when we combine like terms, such as 2x and 3x, we add or subtract their coefficients.

Since, we have to combine the like terms of the given expression 4t-(t+3t).

Here 4t, t and 3t both are the like terms.

So, we add and subtract coeffcients of t to simplify the given expression.

Therefore, the simplification of 4t - (t + 3t) is given by

4t -( t+ 3t)
