Answer:
12i √5
Step-by-step explanation:
12i √5 is the answer. You have a negative square root so the answer must have the i, for imaginary number, in it.
Answer:
The correct answer is 26.8328157
Step-by-step explanation:
All you have to do to get this answer is you have to...
Let sqrt (x) - sqrt(y) be the square root.
6 - sqrt(20) = x + y - 2 * sqrt(xy)
So x+y = 6. And x * y = 5.
Clearly x = 5 and y = 1, as we want positive square root.
Answer = sqrt 26.8328157

Jan walks each morning for exercise. She takes a drink of water as she completes every 3/4 of a mile. She walks a total of 4 1/2 miles. How many times does she take a drink?
Answer:
Jan takes a drink 6 times.
Step-by-step explanation:
The information provided is:
Jan takes a drink of water as she completes every 3/4 of a mile. She walks a total of 9/2 miles.Compute the number of times Jan takes a drink as follows:
[tex]\text{Number of times Jan takes a drink}=\frac{\text{Number of miles walked}}{\text{Interval for a drink}}[/tex]
[tex]=\frac{9/2}{3/4}\\\\=6[/tex]
Thus, Jan takes a drink 6 times.
There are 32 marbles in the box. There are 12 red marbles, 14 blue marbles, and 6 yellow marbles. What percent of the marbles are NOT yellow?
Answer:
Around 82-81% aren't yellow.
Step-by-step explanation:
Add together the number of marbles that aren't yellow and divide the total of NON YELLOW with the total (32) to get around 82-81%.

What are Parallel lines?
Parallel lines are those lines that are equidistance from each other and never intersect each other.
Given that;
Two lines x and y are parallel.
w is transversal of x and y.
Now, To prove ∠4 ≅ ∠5 we use;
Since, Two lines x and y are parallel.
So, We can apply all the properties of angles of triangles.
Statements Reasons
1. x || y 1. Given
2. w is transversal 2. Given
3. ∠4 ≅ ∠1 3. Vertically opposite angles.
4. ∠1 ≅ ∠5 4. By Corresponding angles theorem.
5. ∠4 ≅ ∠5 5. By Transitive property.
Thus, The correct explanations are;
A) Vertical angles.
B) Corresponding angles theorem
C) Transitive property.

2. Toss 4 times Imagine tossing a fair coin 4 times . (a ) Give a probability model for this chance process . (b) Define event B as getting exactly three tails . Find P(B)
Answer:
If a coin is tossed 4 times; number of possible outcomes = (2^4) = 16. 3 heads and 1 tail can occur from 4 tosses in (4C3)*(1C1) = 4*1 = 4 ways. So, the probability = (4 / 16) = (1 / 4) = 0.25.
i didnt really understand the question but hope this helps
According to the information given, we have that:
a) A binomial model with [tex]p = 0.5[/tex] and [tex]n = 4[/tex] should be used.b) P(B) = 0.25.For each coin, there are only two possible outcomes, either it is heads, or it is tails. The result of the flip of a coin is independent of any other flip, hence, the binomial distribution is used to solve this question.
Binomial probability distribution[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
The parameters are:
x is the number of successes. n is the number of trials. p is the probability of a success on a single trial.Item a:
The coin is tossed 4 times, hence [tex]n = 4[/tex].It is a fair coin, hence equally as likely to be heads and tails, which means that [tex]p = 0.5[/tex].Hence, a binomial model with [tex]p = 0.5[/tex] and [tex]n = 4[/tex] should be used.
Item b:
P(B) is P(X = 3), hence:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 3) = C_{4,3}.(0.5)^{3}.(0.5)^{1} = 0.25[/tex]
Hence, P(B) = 0.25.

Step-by-step explanation:
AB:
d = sqrt ( (−5−2)^2 + (−2−(−8))^2)
d = sqrt( (−7)^2 + (6)^2 )
d = sqrt(49+36)
d = sqrt(85)
d = 9.219544
BC:
d = sqrt ( (−7−(-5))^2+(3−(−2))^2 )
d = sqrt( (−2)^2 + (5)^2 )
d = sqrt(4+25)
d = sqrt(29)
d = 5.385165
AC:
d = sqrt ( (−7−(2))^2+(3−(−8))^2 )
d = sqrt( (−9)^2 + (11)^2 )
d = sqrt(81+121)
d = sqrt(202)
d = 14.21267
DE:
d = sqrt ( (−11−(-9))^2+(12−7)^2 )
d = sqrt( (−2)^2 + (5)^2 )
d = sqrt(4+25)
d = sqrt(29)
d = 5.385165
EF:
d = sqrt ( (−2−(-11))^2+(1−12)^2 )
d = sqrt( (9)^2 + (-11)^2 )
d = sqrt(81+121)
d = sqrt(202)
d =14.21267
DF:
d = sqrt ( (−2−(-9))^2+(1−7)^2 )

Answer:
(3x-1)(2x+1)
Step-by-step explanation:
1-6x^2-x=0
-6x^2-x+1=0
6x^2+x-1=0
6x^2+(3-2)x-1=0
6x^2+3x-2x-1=0
3x(2x+1)-1(2x+1)=0
(3x-1)(2x+1)=0

Point A is located at the x-coordinate x=-4 and y-coordinate y=1.
Hence, the coordinates of point A = (-4, 1)
Part b)
Point B(3, -2) has been plotted and is shown in the attached figure.
It is clear from the attached diagram that point B is located at the x-coordinate x=3 and y-coordinate y=-2. Hence, the coordinates of point B = (3, -2)
