Answer:

greater for the data set 1.

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.

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

A variable is a place where values are kept. The number of students in Shawn's school with at least one sibling is 367.

A variable is a quantity that could change depending on the circumstances of an experiment or mathematical problem. Typically, a variable is denoted by a single letter. The general symbols for variables most frequently used are the letters x, y, and z.

A variable is a symbol and a stand-in for any mathematical object in mathematics. A variable can specifically denote a number, a vector, a matrix, a function, its argument, a set, or one of its elements.

Let the number of students be x, then

25/32 = x/470

simplifying the above equation, we get

25(470) = 32x

32x = 11750

Dividing both sides of the equation by 32, we get

32x / 32 = 11750 / 32

x = 367

The value of x = 367.

Therefore, at least one sibling is present among 367 kids at his school.

The orthocenter of the ΔABC is ( -1,5 ).

In a right triangle, the orthocenter is the polygonal vertex of the right angle. When the triangle's vertices and orthocenter are joined, any point becomes the orthocenter of the other three points, according to Carnot (Wells 1991). These four locations thus form an orthocentric system.

Given the  co-ordinates A( -3,3 ), B( -1,7 ) and C( 3,3 ).

To find the orthocenter using below steps:

1. First, we find the equations of AB and BC.

The general form of a line is y = mx + b

where m is the slope and b is the y-intercept.

Using the formula of slope given [tex]$m =\frac{y_2 - y_1}{x_2 - x_1}[/tex]  , we will find the slope of AB and BC.

Now, slope of AB is m = (7-3/-1 + 3)  

i.e. m = (4/2) = 2

Putting this 'm' in the general form and using the point B(-1, 1), we get the y-intercept as,

y = mx + b

1 = 2 × (-1) + b

i.e. b = 3.

So, the equation of AB is y = 2x + 3.

Also, slope of BC is m=(3-7/3+1)  i.e. m=-4/4 i.e. m--1

Putting this 'm' in the general form and using the point B( -1,1 ), we get the y-intercept as,

y = mx + b i.e. 1 = (-1) × (-1) + b i.e. b = 0.

So, the equation of BC is y = -x.

2. We will find the slope of line perpendicular to AB and BC.

When two lines are perpendicular, then the product of their slopes is -1.

So, slope of line perpendicular to AB is [tex]m*2=-1[/tex]  i.e. m = -1/2

So, slope of line perpendicular to BC is  i.e.[tex]m*-1=-1[/tex] i.e. m = 1.

3. We will now find the equations of line perpendicular to AB and BC.

Using the slope of line perpendicular to AB m=-1/2 i.e.  and the point opposite to AB

i.e. C(3, 3), we get,

y = mx + b

i.e. [tex]3=-1/2*3+b[/tex]  

i.e. b = 9/2

So, the equation of line perpendicular to AB is

[tex]y=-x/2+9/2[/tex]

Again, using the slope of line perpendicular to BC i.e. m = 1 and the point opposite to BC

i.e. A( -3,3 ), we get,

y = mx + b

i.e. 3 = 1 × -3 + b

i.e. b = 6.

So, the equation of line perpendicular to BC is y = x+6

4. Finally, we will solve the obtained equations to find the value of (x, y).

As, we have y = x + 6 and  y = -x/2 + 9/2

This gives, y = -x/2 + 9/2 → x + 6

y = -x/2 + 9/2

simplifying the above equation, we get

2x + 12 = -x + 9

3x = -3

x = -1.

So, y = x + 6

simplifying the above equation, we get

y = -1 + 6

y = 5.

The value of x = -1 and y = 5.

Hence, the orthocenter of the ΔABC is ( -1,5 ).

   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)

Answer:

Total Money = $ 75.00

Step-by-step explanation:

Let X be the Total Money

Amount Spent for Shopping = 2/3 of X = 2X/3

Money Lost = 3/5 of (X -2X/3) = 3/5 of (3X-2X)/3 = 3X/15 = X/5

Balance in hand = $ 10.00

is X - 2X/3 - X/5 = $ 10.00

LCM of 3 and 5 = 15

ie (15X - 10X - 3X)/15 = $ 10.00

(15X - 10X - 3X) = 150.00

2X = $ 150.00

X = $ 150.00/2

X = $ 75.00

Step-by-step explanation:

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]
