Find the distance between y=1/2x+2 and x-2y=6
Show work and give exact distance
The distance between these two lines y=1/2x+2 and x-2y=6 is 10/√5
Distance between two lines:
We know that, the parallel lines can be extended till infinity. The slopes of two parallel lines are equal.
Distance d between two parallel lines
y = mx + c1 and
y = mx + c2 is calculated by the
d = |C1–C2|/√(A² + B²)
Given,
Here we have the two line equation they are,
y=1/2x+2 and x-2y=6
And we need to find the distance between them.
To find the distance between the lines, then we ahve to make the equation into standard form, that is,
y = mx + c
Here the first equation is in standard form, so we have to convert the second one,
So, the second equation is written as,
x - 2y = 6
-2y = 6 - x
y = (6 - x)/-2
y = -3 + 1/2 x
y = 1/2 x - 3
Now, we have to derive the value of the following from the given equation, then we get,
Slopes are same m1 = m2 = 1/2 and c1 = 2 ,c2 = -3.
here a = 1/2, b = -1
Now, apply the values on the formula, then we get,
d = |2 - (-3)|/√(1/2)² + (-1)²
d = 5/√1/4 +1
d = 5/√5/4
d = 5/√5/2
d = 10/√5
Therefore, the distance between these two equation is 10/√5.

The
measure of an acute angle is represented by (3x + 12)°. which is not a possible value of x
Answer:
I don't know about this b
Answer:
possible value would be 28
Step-by-step explanation:
an acute angle is an angle less then 90° , that is
3x + 12 < 90 ( subtract 12 from both sides )
3x < 78 ( divide both sides by 3 )
x < 26
thus any value of x greater than 26 is not possible
so x = 28 is a possible value of x
water is poured into a right cylindrical tank at a rate of 6 cubic inches per minute. if the radius of the base is 20 incheas long; how fast is the hieght changing when the water level is 12 inches high?
According to the formula of cylindrical volume, we can find out that the rate at which the height of the water level is changing is [tex]\frac{3}{200\pi } inch/min[/tex].
Water is increasing at a rate of ( 3/200π ) inch/min in a cylindrical tank.
It is given to us that, for a right cylindrical tank,
Radius of the base, r = 20 inch ----- (1)
The rate of water poured into the cylindrical tank,
[tex]\frac{dV}{dt}[/tex] = 6 cubic inch per min ------- (2)
We have to find out the rate of change of height when the water level is 12 inches high.
This implies, we need to calculate [tex]\frac{dh}{dt}[/tex].
To find out [tex]\frac{dh}{dt}[/tex] , we have to use the equation for the volume of a right cylinder.
Let us say, the volume of cylinder is represented as V
We know, the formula of volume of a cylinder is
[tex]V = \pi r^{2} h[/tex] ------(3)
Substituting the value of r from equation 1 in equation 3, we will get
[tex]V = \pi r^{2} h\\= > V = \pi 20^{2} h\\= > V = \pi 400 h[/tex] ----- (4)
Differentiate equation (4) with respect to time,
[tex]\frac{d}{dt} V = \frac{d}{dt}[ \pi 400 h]\\= > \frac{dV}{dt}= \pi 400\frac{dh}{dt}[/tex] ----- (5)
Substituting the value of [tex]\frac{dV}{dt}[/tex] from equation (2) in equation (5), we have
[tex]6 = \pi 400\frac{dh}{dt}\\= > \frac{dh}{dt} = \frac{6}{400\pi }\\= > \frac{dh}{dt} = \frac{3}{200\pi } inch/min[/tex]

To find out if the system has a single solution, we have to check wheter its equations are not equivalent to one another and no equation contraticds the others.
If these are some cases, we will find out while we answer, because you will either find an equation that the variable can have any number or we will get to an equation that is wrong for any value of the variable.
To find the solution, we will have to reduce the system to two variable and then to one variable.
To do this, we can pick a variable to get rid of and pair equations so we can achieve this.
Let's get rid of variable y by elimination.
Firstly, we can see that the first equations can by simplifies by dividing it by 3:
[tex]\begin{gathered} (3x-3y-3z=3)\div3 \\ x-y-z=1 \end{gathered}[/tex]Now, since we want to eliminate y, we need to match its coefficient with another equation, but with opposite sign.
The second equation has a coefficient of -2 on y, so if we multiply the first simplified equation by -2, we will get:
[tex]\begin{gathered} (x-y-z=1)\times(-2)_{} \\ -2x+2y+2z=-2 \end{gathered}[/tex]Now, we can add this equation with the second:
[tex]\begin{gathered} -2x+2y+2z=-2 \\ 7x-2y-z=-4 \\ --------------- \\ 5x+0y+z=-6 \\ 5x+z=-6 \end{gathered}[/tex]Now, we will do similarly but with the last equation. The coefficient of y on it is -4, so we multiply the first simplified equation by (-4):
[tex]\begin{gathered} (x-y-z=1)\times(-4) \\ -4x+4y+4z=-4 \end{gathered}[/tex]And add the third equation to it:
[tex]\begin{gathered} -4x+4y+4z=-4 \\ -6x-4y-6z=-1 \\ -------------- \\ -10x+0y-2z=-5 \\ -10x-2z=-5 \end{gathered}[/tex]Notice that we can change the sign of all terms on this equation:
[tex]10x+2z=5[/tex]Now, we have two equations and two variable:
[tex]\begin{gathered} 5x+z=-6 \\ 10x+2z=5 \end{gathered}[/tex]However, notice that the left side of the equations are equivalent, because if we multiply the first equation by two, we will get the pair:
[tex]\begin{gathered} 10x+2z=-12 \\ 10x+2z=5 \end{gathered}[/tex]So, the left side is equivalent, but the right sides are different, this means that one equation contradicts the other, That is, there is no possible pair of x and z so that these equations are both true.
This means that there is no solution to this system of equations.

Comparing numbers is a technique for determining if one number is equal to, smaller than, or larger than the other numbers. To compare two numbers, we write them using several symbols. In our daily lives, we make comparisons of figures, such as the daily temperature, the cost of things used on a regular basis, our height and weight, etc. The number with more digits is greater than the number with fewer digits when they are natural numbers.
Miles drove by Tia = 127 miles a week
Miles driven by Mac = Miles driven by Tia*23

A 8 letter Code word is selected. What is the probability that there are no repeated letters?
Answer:
0.3016
Step-by-step explanation:
If we have an 8 letter code word...
Total number of possible letters = 26
The number of letters possible = 8
So...
26 ^ 8 = 0.3016
Hope this helps!
Answer:
[tex]\approx 0.30164[/tex]
Step-by-step explanation:
The Alphabet contains 26 characters, and to better understand this probability, let's do each letter one step at a time.
Any letter being chosen should have an equal probability of: [tex]\frac{1}{26}[/tex], and for the first letter we don't really have to worry about choosing a non-repeated letter, since it's impossible to have a non-repeated letter on the first letter... since it's the first letter, so no other letter has been chosen.
This means we have a probability of: 1 to get a non-repeated letter when we choose the first letter.
The probability when we choose the 2nd letter is different, since there is a possibility of choosing a repeated letter. As stated above, the probability of choosing any one letter should be equal for each letter and is: [tex]\frac{1}{26}[/tex]
Since we want to avoid this one letter we choose in the beginning, the probability of choosing it is: [tex]\frac{1}{26}[/tex], which means the probability of not choosing it is: [tex]\frac{25}{26}[/tex]
For the 3rd letter it follows the same pattern, assuming we have two non-repeated letters, the probability of choosing a repeated letter from the previous two is there combined probabilities of: [tex]\frac{1}{26} + \frac{1}{26} = \frac{2}{26}[/tex]. Since we want a non-repeated letter, we subtract this probability from one, because the entire probability will equal one.
This gives us a probability of: [tex]\frac{24}{26}[/tex] of choosing a non-repeated letter.
You'll notice a pattern, the numerator is decreasing by one! This makes sense since each time we choose a non-repeated letter, well the number of non-repeated letters will decrease by one.
This gives us the probability for each letter up to eight letters
[tex]\frac{26}{26}, \frac{25}{26}, \frac{24}{26}, \frac{23}{26}, \frac{22}{26}, \frac{21}{26}, \frac{20}{26}, \frac{19}{26}[/tex]
To get an eight letter code that has no no repeated letters, all these events have to occur. To find the collective probabilities of all these events happening, we simply multiply them, assuming they're independent which we have no reason to believe they aren't independent.
This gives us a total probability of approximately: [tex]0.30164[/tex]

Jonny, Becky and Sara share £138.
The ratio of the amount of money Jonny gets to
the amount of money Sara gets is 1:4.
Jonny gets £69 less than Sara gets.
What percentage of the £138 does Becky get?
If Johny receives £x, then Sara will receive £4x (Given ratio is 1:4).
Describe ratio.In mathematics, a ratio shows how many times one number is contained in another.
For instance, if there are eight oranges and six lemons in a fruit plate, the orange to lemon ratio is eight to six (that is, 8:6, which is equivalent to the ratio 4:3).
Similarly, the ratio of oranges to total fruit is 8:14, while the ratio of lemons to oranges is 6:8 (or 3:4). (or 4:7). Numbers in a ratio can represent any quantity, including counts of people or objects, weights, lengths, times, and so on. Most of the time, both numbers have to be positive.
If Johny receives £x, then Sara will receive £4x (Given ratio is 1:4).
assumable, 4x - x = £69
or, 3x = 69
or, x = 69/3 = £21
Then Johny receives £21 and Sara receives £84 (4x£21).
Becky receives £(138-(21+84)) = £33 as well.
Her proportion in the ratio is equal to (33/138) x 100% (23.91%).

y = mx + b.
In which the parameters of the function are as follows:
m is the slope.b is the y-intercept.For the cost functions in this problem, we have that:
The slope is the cost per GB.The intercept is the flat cost.Hence the functions are given as follows:
A(x) = 50 + 10x.B(x) = 60 + 8x.The costs will be the same when:
A(x) = B(x)
Hence:
50 + 10x = 60 + 8x
2x = 10
x = 5 GB are used.
If two functions have the same slope and different intercept they are parallel, that is, they never intersect, hence if company A starts charging $8 per GB, this will happen.
The costs will always be the same when the functions are equal, that is, if:

For the given question, the line AC and DF are found to be parallel lines.
What is defined as the parallel lines?Parallel lines are two or more lines which lie within the same plane but never intersect.
The basic properties listed below make it simple to identify parallel lines.
Parallel lines are defined as straight lines which are everytime the same distance apart.Parallel lines, no matter how far they are extended for either direction, never meet.For the given parts:
Part 19: Line AC || Line DF
57° + ∠B = 180° (linear pair)
∠B = 123°
∠B = 123° (corresponding angles are equal)
Thus, Line AC || Line DF
Part 20: Line AC || Line DF
∠B = 143° (vertically opposite angles)
Then, ∠B + 37° = 143° + 37° = 180° (linear pair)
Thus, Line AC || Line DF
Part 21: Line AC || Line DF
62° + ∠B = 180° (linear pair)
∠B = 118°
And, ∠E = 62° (alternate interior angles)
So, ∠B + ∠E = 118° + 62° = 180° (linear pair)
Thus, Line AC || Line DF
Part 22: Line AC || Line DF
∠B = 180° - 115° = 65°
∠B = 65° (alternate interior angles)
Thus, Line AC || Line DF
