   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

Answer:

2 times as much

Step-by-step explanation:

1 hour 2/3 = 60 + (2/3) 40 mins = 100 minutes

200 is twice as much as 100

The slope is -A/B and y-intercept is C/B in the line (A/D)x + (B/D)y = C/D

A line's steepness and direction are determined by the slope of the line. Without actually using a compass, determining a line's slope in a coordinate plane allows one to anticipate whether a line is parallel, perpendicular, or not.

The change in a line's y coordinate relative to its change in x coordinate is referred to as the line's slope. Δy is the net change in the y coordinate, while Δx is the net change in the x coordinate.  

Therefore,

m =  y₂-y₁/x₂-x₁ (where m denotes the slope) can be used to express how the y coordinate changes in relation to the x coordinate.

Be aware that tan ∅ = y/x.

We also refer to this tan as the line's slope

We know that the equation for slope(m) and y - intercept(c) of a line is given by :

y = mx + c

Here the equation is give as (A/D)x + (B/D)y = C/D, lets simply

⇒ (A/D)x + (B/D)y = C/D

⇒ B(y)/D = C/D -(A/D)x

⇒ [tex]\frac{B(y)}{D}[/tex] = [tex]\frac{C -A(x)}{D}[/tex]

⇒ B(y) = C - A(x)

⇒ y = [tex]\frac{C -A(x)}{B}[/tex]

⇒ y = [tex]\frac{ -A}{B}x + \frac{C }{B}[/tex]

Here, slope is -A/B and y-intercept is C/B

Using rational numbers, Jackson supports more education funding as he  7/20 > 6/20.

Any number that can be expressed as a fraction and where the denominator (the bottom number) and the numerator (the top number) are both integers is considered a rational number. In other words, p/q, where p and q are both integers and q 0, can be used to represent a rational number.

According to Kirsten, 24% of federal tax dollars should fund education

⇒ 24% = 24 / 100

⇒ 6/25

According to Jackson, $0.35 of every tax dollar should go toward education

The monthly payment for Jake borrowing $41,000 for 5 years at a 3% APR is $736.72.

Monthly payments are equal periodic payments made to offset an outstanding liability.

The monthly payments are the compounded principal (Principal + Compound Interest amount) divided by the number of periods.

The  monthly payments can be computed using an online finance calculator as follows:

N (# of periods) = 60 months (5 years x 12)

I/Y (Interest per year) = 3%

PV (Present Value) = $41,000

FV (Future Value) = $0

Results:

Monthly Payment (PMT) = $736.72

Sum of all periodic payments= $44,203.20

Total Interest = $3,203.20

Thus, Jake who borrowed $41,000 for 5 years at a 3% APR needs to make a monthly payment of $736.72 to settle the principal and the compounded interest.

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

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

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).

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

Step-by-step explanation:

Based on the number of people going to see the movie and the price of the snacks, the total that Genesis would pay if she bought 6 snacks is $78.

The amount that Genesis would pay if she bought x snacks is 60 + 3x.

The total cost to Genesis can be found as:

= (Number of people going to watch movie x Price of ticket) + (Price per snack x number of snacks)

= (4 people including Genesis x 15) + (3 x 6)

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.
