Answer:

y = [tex]\frac{1}{2}[/tex] x + 5

Step-by-step explanation:

Perp means perpendicular?

Perpendicular slopes are the opposite reciprocals of each other.  So the slope would be [tex]\frac{1}{2}[/tex]

Use -4 for x and 3 for y and the slope of [tex]\frac{1}{2}[/tex] to find the y intercept

y=mx +b

3 = [tex]\frac{1}{2}[/tex](-4) + b  

3 = -2 + b  Add 2 to both sides

5 = b

y = mx +b  We know the slope (m) is [tex]\frac{1}{2}[/tex] and the y intercept (b)  is 5.

y=mx+ b

y = [tex]\frac{1}{2}[/tex] x + 5

The change will be that of run over run.

Step-by-step explanation:

In the equation, y= -3x - 2 it moves 3 spaces down directly on the y-axis and 1 space to the right from there in the direction of the x-axis. Although, if you were to change the slope from -3 to -1/3 it will move 1 space down directly on the y-axis and 3 spaces to the right from there in the direction of the x-axis.

Answer:

[tex]5x^4-24x^3-34x^2-12x[/tex]

The linear equation is written as:

y = (-1/2)*(x + 3) + 2

And its graph can be seen in the image at the end.

Here we don't have the options, so I will post the graph of the line.

A linear equation with a slope a and a known poing (h, k) is written as:

y = a*(x - h) + k

Here we know that the slope is -1/2 and the point is (-3, 2), then the linear equation is:

y = (-1/2)*(x + 3) + 2

To graph the linear equation we just need to find two points on the line and connect them with a line, we already know one, so let's find another.

If we use x = 1, then:

y = (-1/2)*(1 + 3) + 2

y = (-1/2)*4 + 2

y = -4/2 + 2 = -2 + 2 = 0

y = 0

The other point is (1, 0)

With these two we can draw the graph you can see below.

The height and radius of the cone-shaped cup that will use the smallest amount of paper, that is the maximum volume is  3.72 and  2.632 respectively.

Formula used in the solution is

Volume of the cone= (1/3)π(r^2)h

Area of the cone= πr√(l^2 + r^2)

Given, the volume of the cone is 27 cm^3.

(1/3)π(r^2)h =27

Simplifying the equation to get the value of r.

π(r^2)=81/h

r^2=81/hπ

[tex]r=\sqrt{\frac{81}{\pi h} }[/tex]

Substituting the value of r in area, we get

[tex]A=\pi \sqrt{\frac{81}{\pi h} } \sqrt{h^{2} + \frac{81}{\pi h} }[/tex]

[tex]\frac{dA}{dh} =\pi \sqrt{\frac{81}{\pi h} } \sqrt{h^{2} + \frac{81}{\pi h} }[/tex]

dA/dh=√81 × (π - 162/[tex]h^{3}[/tex]) × 1/√(πh + 81/[tex]h^{2}[/tex])

At dA/dh=0, we will get,

√81 × (π - 162/[tex]h^{3}[/tex]) × 1/√(πh + 81/[tex]h^{2}[/tex])=0

√81 × (π - 162/[tex]h^{3}[/tex])=0

[tex]\pi - \frac{162}{h^{3} }=0[/tex]

Thus, [tex]\pi h^{3} -162=0[/tex]

[tex]\pi h^{3} =162[/tex]

[tex]h^{3} =\frac{162}{\pi}[/tex]

h^3= 51.5662015618

h= 3.7221

Now, substitute h in radius,

[tex]r=\sqrt{\frac{81}{\pi \times 3.7221} }[/tex]

r=2.632

Hence, the height of the cone shaped cup is 3.7221 and the radius is 2.632.

Two cars leave at the same time but travel at different speeds. Car a travels 20 miles per hour faster than car b. In the time it takes car a to travel 350 miles, car b travels 250 miles.

The number of hours needed for Car B to overtake Car A is greater then 5 hours, Car A = 60km/h; Car B= 75km/h.

After h hours, the number of kilometers covered by Car A is 60*h

After h hours, the number of kilometers covered by Car B is 75(h-1)… since Car B started one hour later.

For Car B to overtake Car A,

The cost of running the ad for three weeks by Enrique will be $207.

To estimate the overall cost for three weeks, we need the amount for one week. Further, we need the cost for six lines advertisement. So, performing calculation for the cost of advertisement of six lines in one week.

Total cost in one week = charge for first two lines + number of additional lines × cost of each additional line

Keep the values in formula. Out of six lines, the additional will be 4 as (6-2=4).

Total cost in one week = 42 + 4×6.75

Performing multiplication

Total cost in one week = 42 + 27

Performing addition

Total cost in one week = $69

Cost for three weeks = 69×3

Performing multiplication

Cost for three weeks = $207

Thus, Enrique will pay $207 for three weeks.

The discount on sales is the amount of money that is being deducted from the original price of an item by a seller to their customers.

The original price for labor= $299.88

The original price for parts = $ 307.54

The original price for others = $ 74.71

The total original price = $682.13

The discount of on the total price = 15%.

That is;

= 15/100 × 682.13

= 10,232.95/100

= $102.32

When discount is removed from the original price;

= 682.13 - 102.32

= $579.81

When the tax is acted on the discount total sales;

= 6/100 × 579.81

The difference between the sum of the numbers is 0.

To find the sum of even number between 305 and 609, and the sum of all the odd numbers between 304 and 608, we use the sum of an arithmetic progression.

Note that there are 103 even numbers between 305 and 609. The even numbers start from 306 and end at 608.

Also, there are 103 odd numbers between 304 and 608. The odd numbers start from 305 and end at 607.

Using the sum of an arithmetic progression S = n/2(a + T) where

Now, for the sum of even numbers between 305 and 609, we have

So, S = n/2(a + T)

= 103/2(304 + 608)

= 103(912)/2

= 103(456)

= 46968

Also, for the sum of odd numbers between 304 and 608, we have

So, S' = n/2(a + T)

= 103/2(305 + 607)

= 103(912)/2

= 103(456)

= 46968

So, the difference between S and S' is d = S - S'

= 46968 - 46968

Where c is the hypotenuse.

Substituting values in gives us (a and b do not matter) :

x² + (√43)² = 21²

Now we simplify :

Using the surd law:

√a ×√a = a

(√43)² = √43×√43 = 43

21² = 441

x² + 43 = 441

Subtract 43 from both sides :

x² + 43 - 43 = 441 - 43

x² = 398

Square root both sides :

x = √398

√398 = 19.9 to 1 d.p.

The value of the vertex for the x-coordinate is less in column 1 as compared to the value of the vertex of x -the coordinate for column 2.

What are the coordinates and vertex of an equation?

When a graph crosses its symmetry axes, the vertex formula in mathematics may be used to get the vertex coordinate of a parabola. The vertex point is often represented by (h, k). We are aware that a parabola's conventional equation is y=a[tex]x^{2}[/tex]+bx+c. The vertex in this case should be near the base of the U-shaped curve if the coefficient [tex]x^{2}[/tex] is positive. The apex of the U-shaped curve should be at the top of the coefficient  [tex]x^{2}[/tex] is negative.

In the given question, It is given:

The two equations are:

[tex]y=2x^{2}-4x+12[/tex]

and,

[tex]y=4x^{2}+8x+3[/tex]

We have to find the vertex of the x-coordinate.

So, for the equation: [tex]y=2x^{2}-4x+12[/tex]

In Column 1:

[tex]\begin{aligned}y &=-2 x^2-4 x+12 \\&=-2\left(x^2+2 x-6\right) \\&=-2\left((x+1)^2-7\right)\end{aligned}[/tex]

So, By comparing the equation, we can say that the x-coordinate of the vertex in the column is -1.

So, for the equation:[tex]y=4x^{2}+8x+3[/tex]

In Column 2:

[tex]\begin{aligned}y &=x^2-4 x+3 \\&=(x-2)^2+(-1)\end{aligned}[/tex]

So, By comparing the equation, we can say that the x-coordinate of the vertex in the column is 2.

So, Option b is correct.

Hence, The value of the vertex for the x-coordinate is less in column 1 as compared to the value of the vertex of x -coordinate for column 2.
