The area of the given triangle is 10 square units.

We have a triangle. The vertices of the triangle are J (-2, 1), K (0, 3), and L (3,-4). We need to find the area of the triangle. We will use the determinant method to calculate the area of a triangle if the coordinates of the vertices are given. If the vertices of a triangle are (x1, y1), (x2, y2), and (x3, y3), then the formula for the area of the triangle is given below.

A = (1/2)|x1(y2 - y3) + x2(y3 - y1) + x3(y1 - y2)|

A = (1/2)|-2(3 - (-4)) + 0(-4 - 1) + 3(1 - 3)|

A = (1/2)|-2(3 + 4) + 0(-5) + 3(-2)|

A = (1/2)|-14 + 0 + -6|

A = (1/2)|-20|

A = 10

Hence, the area of the triangle is 10.

The equation of a line perpendicular to y = -3/4x +1 and passes through (12, 9) is y = 4  /3 x - 7

A linear graph can be represented in slope intercept form as follows:

y = mx + b

where

The line passes through the points (12, 9) and its perpendicular to the graph y = -3/4x +1.

The products of the slope of perpendicular lines is equals to negative one.

Therefore,

m₁ m₂ = -1

Hence,

- 3 / 4 m₂ = - 1

cross multiply

-3m₂ = -4

m₂ = 4 / 3

Therefore, let's find the y-intercept of the line using (12, 9)

y = 4 / 3 x + b

9 = 4  /3(12) + b

9 = 16 + b

b = 9 - 16

b = - 7

Therefore, the equation of the line is y = 4  /3 x - 7

Answer:

57 half dollars and 169 quarters

Step-by-step explanation:

We will need a system of equations to solve this problem.

Given that the number of quarters is 2 less than three times the number of half dollars, we have Q = 3H - 2

Thus, we have 0.25Q + 0.50H = 70.75 and Q = 3H - 2.

The second equation allows us to use substitution:

[tex]0.25(3H-2)+0.50H=70.75\\0.75H-0.50+0.50H=70.75\\1.25H=71.25\\H=57[/tex]

We can plus this 57 into the second equation to find the number of quarters:

[tex]Q = 3(57)-2\\Q=169[/tex]

The cost that the manager will pay for turkey and cheese is $127.182.

From the information, the manager wants to find the total cost of 24.8 pounds of sliced turkey at $1.89 a pound and 38.2 pounds of provolone cheese at $2.05 a pound.

The total cost will be:

=> Cost for turkey + Cost for cheese

= (24.8 × $1.89) + (38.2 × $2.05)

= $48.872 + $78.31

= 127.182

The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity. The general form of representing a ratio of between two quantities say 'a' and 'b' is a: b

The ratio of mark to Mary to gabrielle is 3:5:8

this means the total ratio is 16 i.e 3+5+8=16

if the total money is y and the money shared to mark is x, then

3/16× y= x

therefore 3y=16x

y= 16x/3 equation 1

Mary receives 600 more than mark,this means Mary share = 600+x

therefore 5/16×y= 600+x

5y= 16(600+x)

5y= 9600+16x equation 2

substitute 16x/3 for y in equation 2

5×16x/3= 9600+16x

80x/3= 9600+16x

multiply both sides by 3

80x= 3(9600+16x)

80x= 28800+48x

collect like terms

80x-48x= 28800

The equation to represent the function P is y=4x as per the given points in the table.

It is easier to see the slope (m) and y-intercept (c) of a line in the slope-intercept form of a linear equation (y=mx+c).

18th-century Switzerland. The first person to present a line's equation in slope intercept format might have been Jakob Hermann.

Y = mx + c is the true slope intercept form. It provides both a slope and an intercept, which is why the form is known as the slope-intercept form.

You can see the line's slope and y-intercept in Slope-Intercept form. One point the line travels through and the slope of the line are both clearly displayed in point-slope form.

We know that, the equation of the line is y=mx+c

If this line passes through (0,0) then,

0=m(0)+c

then, c=0

Now, substituting the point (1,4) in the above equation and c=0 then we get,

4=m(1)+0

m=4

Now substitute the point (2,8) then,

8=m(2)+0

m=4

Similarly, by substituting the points  (3,12), (4,16), (5,20), (6,24) we get,

m=4

Now, by substituting c=0 and m=4 in the above equation we get,

y=4x+0

y=4x

Therefore, the equation to represent the function P is y=4x

To solve this problem, first we have to rewrite the problems into some equations, such:

s' = 672 --> represent this year's sale

Then, we should define

the increase on the sale

by finding the difference between the last year'ssale and this year's sale.

Δs = s'-s

Δs = 672 - 480

Δs = 192

The effective tax rate is 24%  for a taxable income of $75,400

The amount of additional tax paid for each new dollar of income received is known as the marginal tax rate. Total taxes paid divided by total income earned is the average tax rate.

the"marginal" income is what is taxed at the next highest tax bracket as moves up in tax brackets, this tax rate is known as the marginal tax rate.

Given that;

Marginal Tax Rate           Chart Tax Bracket

$0 –$10,275                                  10%

$10,276 –$41,175                           12%

$41,176 –$89,075                          22%

$89,076 –$170,050                      24%

$170,051 –$215,950                      32%

$215,951 –$539,900                     35%

> $539,901                                     37%

Thus, the effective tax rate for income of $95, 600 lies in the range of a marginal tax rate of 24%.

Step-by-step explanation:

Hello,

41175 - 10276 = 30899

30899  × 12% = 3707.88

Then we would input 75400 since it fits in to ($41176–$89075)

75400 - 41176 = 34224

34224 × 22% = 7529.28

Then we would add it all up

The maximum tangential speed that the ball can have is 3.89 m/s. Centripetal acceleration is 0.06561 and tangential speed of ball will be 0.243 m/s

The centripetal force is the force needed to keep a body moving in circular motion. It exists for circular motion. Example - rotation of earth around sun.

We have an athlete swings a 7.9 kg ball horizontally on the end of a rope. The ball moves in a circle of radius 0.9 m at an angular speed of 0.27 rev/s.

[A] -

Tangential speed of ball = v = rω = 0.9 x 0.27 = 0.243 m/s

[B] -

Centripetal acceleration = a[c] = rω² = 0.9 x 0.27 x  0.27 = 0.06561

[C] -

Maximum tension = Maximum centripetal force = mrω² = 132.3

ω² = 132.3/mr

ω² = 18.60

v² = 18.60r²

v = 3.89 m/s

Therefore, the maximum tangential speed that the ball can have is 3.89 m/s. Centripetal acceleration is 0.06561 and tangential speed of ball will be 0.243 m/s

The equations that passes through the points (-4, -16) and (5, 2) are: y – 2 = 2(x – 5), y = 2x – 8, and y + 16 = 2(x + 4).

To determine if an equation passes through a given point, plug in the values of the x and y coordinates of the point into the equation to see if it would make the equation true. If it is true, then the equation passes through the points.

Alternatively, graph the equation on a coordinate plane to see if it passes through the given point.

The graph shows the equations given.

The red line represents y + 4 = 2(x – 16).

The blue line represents y – 2 = 2(x – 5), y = 2x – 8, and y + 16 = 2(x + 4).
