your friend claims that because you can find the distance from a point to a line, you should be able to find the distance between any two lines. Is your friend correct? Explain your reasoning.​

Answer:

  yes

Step-by-step explanation:

Yes, you can find the distance between two lines using the formula for the distance to a line.

In general, the notion of distance between two lines only make sense when the lines are parallel.

The usual formula for the distance between a point (x, y) and the line ...

  ax +by +c = 0

is ...

  d = |ax +by +c|/√(a^2 +b^2)

Two lines that are parallel will differ only in their values of 'c'. That is, if the two lines are ...

ax +by +c1 = 0ax +by +c2 = 0

we can arrive at the formula by considering a point (x, y) such that it satisfies the equation for line 2: ax +by +c2 = 0. The distance of that point from line 1 will be ...

  d = |ax +by +c1|/√(a^2 +b^2)

Since we can add or subtract 0 from anything without changing its value, we choose to subtract 0 from the numerator:

  d = |(ax +by +c1) -(ax +by +c2)|/√(a^2 +b^2)

Simplifying gives ...

  d = |c1 -c2|/√(a^2 +b^2)

9. A car is traveling in a straight line path at a maximum speed of 7.00 m/s. The
driver of the vehicle applies the brakes bringing the car to a stop after traveling
10.0 m. What is the magnitude of the car's acceleration to the nearest
hundredths place?

Answers

Answer:

30mph

Step-by-step explanation:

The magnitude of the car's acceleration is 2.45 m/[tex]\rm sec^2[/tex] and this can be determined by using the equation of kinematics.

Given :

A car is traveling in a straight-line path at a maximum speed of 7.00 m/s.The  driver of the vehicle applies the brakes bringing the car to a stop after traveling  10.0 m.

According to the kinematics:

[tex]\rm v = u + at[/tex]     --- (1)

where v is the final speed, u is the initial speed, a is the acceleration and t is time.

Now, put the known terms in equation (1).

0 = 7 + at

at = -7  

[tex]\rm t = -\dfrac{7}{a}[/tex]      --- (2)

From the kinematics the displacement is given by the equation:

[tex]\rm S =ut+\dfrac{1}{2}at^2[/tex]

Now, put the values of u, S, and t in the above equation.

[tex]10=7\times \dfrac{-7}{a}+\dfrac{1}{2}\times a \times \dfrac{49}{a^2}[/tex]

Now, simplify the above equation.

[tex]10=-\dfrac{49}{a}+\dfrac{49}{2a}[/tex]

20a = -49

a = -2.45

So, the magnitude of the car's acceleration is 2.45 m/[tex]\rm sec^2[/tex].

Susan is buying supplies for a party. Spoons only come in bags of 12 and forks only come in bags of 22.


What is the least number of spoons and the least number of forks she can buy so that she has the same number of each?.

Answers

Answer:

The least number of spoons = 11 spoons

The least number of forks = 6 forks

Step-by-step explanation:

We are told in the question:

Spoons only come in bags of 12

Forks only come in bags of 22.

This is an LCM question, hence, we find the Multiples of 12 and 22

The first common multiple is found and this is the lowest common multiple.

Multiples of 12:

12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 132, 144, 156

Multiples of 22:

22, 44, 66, 88, 110, 132, 154, 176

Therefore,

LCM(12, 22) = 132

The least number of supplies she can have is 132.

So therefore,

The least number of spoons = 132 ÷ 12 bags of spoons = 11 spoons

The least number of forks = 132 ÷ 22 bags of forks = 6 spoons.

Answers

Answer:

Step-by-step explanation:

you have to divid 52 by 0.50 i think

Step by step:
The equation is: y = 0.50x + 35

Now you’re going to plug 52 in y as the total.

52 = 0.50x + 35
-35 = 0.50x -35

(Then subtract both sides by 35)


It will equals to: 17 = 0.50x


17 = 0.50x
———= ———-
0.50 = 0.50

Now divide both sides by 0.50)

Find the dimensions of the rectangular box of maximum volume if the sum of the length, width, and height equals 180. (Give exact answers. Use symbolic notation and fractions where needed.)

Answers

Step-by-step explanation:

Let the dimension of the box be x, y and z.

Volume of the box V = xyz

Since the box is a rectangular box, the base will be a square of equal length.

V = x²h where h is the height of the box

If the sum of the length, width, and height equals 180, then x+x+h = 180

2x+h = 180

h = 180-2x

Substitute h = 180-2x into the volume of the box

V = x²(180-2x)

V = 180x²-2x³

The box has its maximum volume when [tex]\frac{dV}{dx} = 0[/tex]

[tex]\frac{dV}{dx} = 360x-6x^{2}[/tex]

[tex]360x-6x^{2} = 0\\360x = 6x^2\\360 = 6x\\6x = 360\\x = \frac{360}{6}\\ x = 60[/tex]

Since 2x+h = 180

Substitute x = 60 into the equation ang get the height h

2(60)+h = 180

120+h = 180

h = 180-120

h = 60

Hence the dimension of the rectangular box is 60 by 60 by 60

The dimensions of the rectangular box of maximum volume are;

Length = 60

Length = 60Width = 60

Length = 60Width = 60Height = 60

Let the dimensions of the rectangular box be;

Length = x

Width = y

Height = h

Volume of a rectangular box is given by;

V = length × width × height

Thus;

Volume of this box in question is;

V = xyz

The box is called a rectangular box because it's sides are rectangular in shape but it's base will be square in shape.

Thus;

width = x and so;

V = x²h

We are given the sum of the length, width, and height of the rectangular box to be equal to 180.

Thus; x + x + h = 180

2x + h = 180

h = 180-2x

Put 180 - 2x for h in the equation for volume;

V = x²(180 - 2x)

V = 180x² - 2x³

The maximum volume will occur at the dimensions when dV/dx = 0. Thus;

dV/dx = 360x - 6x²

At dV/dx = 0, we have;

360x - 6x² = 0

6x² = 360x

x = 60

Recall that; h = 180 - 2x, thus;

h = 180 - 2(60)

h = 60

In a certain​ chemical, the ratio of zinc to copper is 4 to 17 . A jar of the chemical contains 663 of copper. How many grams of zinc does it​ contain?

Answers

Answer:

The jar contains 156 grams of zinc

Step-by-step explanation:

Ratios

Let's call

Z=gr of zinc

C=gr of copper

We know the ratio between them in a certain chemical is:

[tex]\displaystyle \frac{Z}{C}=\frac{4}{17}[/tex]

The jar of the chemical contains C=663 gr of copper. Calculate the grams of zinc by solving the above relation for Z:

Multiplying by C:

[tex]\displaystyle Z=\frac{4}{17}\cdot C[/tex]

Substituting the value of C:

[tex]\displaystyle Z=\frac{4}{17}\cdot 663[/tex]

Z=156 gr

The jar contains 156 grams of zinc

A product's demand per period follows a normal distribution with mean of 60 and standard deviation of 10. The lead time is 3 periods. What order-up-to level should be used to achieve at least a 90% in-stock probability?

Answers

Answer:

209

Step-by-step explanation:

Since the lead time is 2 periods at the time of order, the stocks should last for 3 periods with the 90% probability.

The z-value of 90$ in stock probability = 1.7

Mean of the demand over is (1 + 1 + 1 )  or (2+1 which is 3)

                                                           = 60 x 3 = 180

Now the standard deviation of demand over the three periods = 17.3

Therefore, the order up level would be  = 180 + ( 1.7 x 17.3 )

                                                                   = 209
