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.
9514 1404 393
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 = 0we 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)
[tex]5/6(-8/15)[/tex]
Answer:
[tex]\displaystyle \frac{5}{6}\cdot \frac{-8}{15}=-\frac{4}{9}[/tex]
Step-by-step explanation:
Fraction Multiplying
The product of two fractions can be obtained by multiplying their numerators and denominators separately. Then, simplify and show the result.
We are given the product:
[tex]\displaystyle \frac{5}{6}\cdot \frac{-8}{15}[/tex]
Multiply as directed:
[tex]\displaystyle \frac{5}{6}\cdot \frac{-8}{15}=\frac{5*(-8)}{6*15}=-\frac{40}{90}[/tex]
Simplifying by 10:
[tex]\displaystyle -\frac{40}{90}=-\frac{4}{9}[/tex]
Thus:
[tex]\boxed{\displaystyle \frac{5}{6}\cdot \frac{-8}{15}=-\frac{4}{9}}[/tex]
Given f(x) = 3x^3 + kx + 1, and x – 1 is a factor of f(x), then
what is the value of k?
Step-by-step explanation:
Hope it helps man ...........
The value of k is -4.
Given that,
The equation is [tex]f(x) = 3x^3 + kx + 1[/tex].And, x - 1 is the factor of f(x).Based on the above information, the calculation is as follows:
[tex]f(x) = 3x^3 + kx + 1\\\\= 3(1)^3 + k(1) + 1\\\\= 3 + k + 1 \\\\k = -4[/tex]
Therefore, we can conclude that the value of k is -4.

Manuel can walk 5 miles In one hour. At this rate, how many miles can he walk in 8 minutes? Round to the nearest tenth
Answer:0.6666664
Step-by-step explanation:
You take 5 and divide by 60. Then multiply by 8.
2/3 of a mile.
If he can walk 5 MILES a hour, lets use 5/60.
Multiply 5/60 by 8 since each minute he travels 5/60 of a MILE.
You get 0.66(repeating) OR 2/3
There are 108 pigeons that need pigeon coops. Each coop can hold up to 7 pigeons. How many coops are needed for all 108 pigeons?
15 coops are needed for 108 pigeons
What is unitary method ?
The unitary method is a technique for solving a problem but first finding the value of a single unit , and then finding the necessary value by multiplying the single unit value
using unitary method
Total pigeon = 108
each coop can hold = 7 pigeons
7 pigeons are held by = 1 coop
108 pigeons will be held by = 108 / 7 = 15.43 =15

Belindas blossom boutique is having a one day sell. Any two daisies cost $1.50. How many daisies could you buy for 8.25
Answer:
11
Step-by-step explanation:
Divide 8.25 by 1.50:
8.25/1.50
= 5.5
Since any two daises cost 1.50, multiply this amount by 2:
5.5(2)
= 11
So, you could buy 11 daisies.

If arc WX = 40' and arc Y Z = 92, find m23.
Answer:
m<3 = 66°
Step-by-step explanation:
<3 is an angle with its vertex inside the circle shown in the diagram. This, it's an internal angle.
The measure of an internal angle is equal to half the sum of the measure of the arcs intercepted.
Thus, the equation that shows relationship between <3 and arc WX and arc YZ is shown below:
m<3 = ½(40 + 92)
m<3 = ½(132)
m<3 = 66°
The measure of m<3 = 66°
Calculation of the measure:Since arc WX = 40' and arc Y Z = 92
So we know that
The measure of an internal angle should be equivalent to half the sum of the measure of the arcs intercepted.
So based on this
m<3 =0.50 (40 + 92)
m<3 = 0.50(132)
m<3 = 66°
hence, The measure of m<3 = 66°

Seventy cards are numbered 1 through 70 , one number per card. One card is randomly selected from the deck. What is the probability that the number drawn is a multiple of 3 AND a multiple of 5 ?
Answer:
[tex]Probability = \frac{2}{35}[/tex]
Step-by-step explanation:
Given
[tex]Total = 70[/tex]
First, we need to list the multiples of 5
[tex]M_5 = \{5,10,15,20,25,30,35,40,45,50,55,60,65,70\}[/tex]
Then, multiples of 3[tex]M_3 = \{3,6,9,12,15,18,21,24,27,30,33,36,39,42,45,48,51,54,57,60,63,66,69\}[/tex]
Next, is to list out the common elements in both
[tex]M_3\ n\ M_5 = \{15,30,45,60\}[/tex]
[tex]n(M_3\ n\ M_5) = 4[/tex]
The required probability is then calculated as thus:
[tex]Probability = \frac{n(M_3\ n\ M_5)}{Total}[/tex]
[tex]Probability = \frac{4}{70}[/tex]
[tex]Probability = \frac{2}{35}[/tex]

Can the determinant of a 2 x 2 matrix be zero
Answer:yes
explanation: It’s given that the determinant of the 2x2 matrix is zero. This means that the rows of the matrix are not linearly independent. i.e one row can be made zero by some transformation. R2 - (a)R1 = 0 for some real number a. If we make R2 zero, the rank can not be 2.
Tracy sells water at a fair in 17oz bottles or 11oz cans. If on one shelf she has 11 containers of water that hold a total of 157oz of water, how many bottles and cans of water are on the shelf?
Answer:
Number of bottles = 6
Number of cans = c
Step-by-step explanation:
Given that:
Container for selling water :
17 oz bottle
11 oz can
Let number of bottles = b
Number of cans = c
b + c = 11 - - - (1)
17b + 11c = 157 - - - (2)
b = 11 - c
Substitute into (2)
17(11 - c) + 11c = 157
187 - 17c + 11c = 157
187 - 6c = 157
-6c = 157 - 187
-6c = -30
c = 30/6
c = 5
From ; b = 11 - c
b = 11 - 5
b = 6
Hence,
Number of bottles = 6
Number of cans = c

6 bottles and 5 cans
