What is another way to name line l?
Answer:
Line UM.
Step-by-step explanation: you can name a line by naming at least two points on it.
Line l can be called line UM, line LM, and line UL because line l is contained in plane S.
What is a straight line?A straight line is a combination of endless points joined on both sides of the point.
The slope 'm' of any straight line is given by:
[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]
m is the ratio of the line,
The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases.
It is given that:
A plane S contains a line l.
It is possible to give a name for line l in different ways.
The line l can be called:
Line UMLine LMLine ULLines that intersect at a right angle are named perpendicular lines. Lines that are always the same distance apart from each other are known as parallel lines.

What is the relative size of (how many times as large) a circle's' circumference C to its diameter, d
Answer:
The circumference is pi times larger than the diameter of a circle.
Step-by-step explanation:
The formula of the circumference of a circle is
C = 2(pi)r = (pi)d
C = (pi)d
To find the ratio of the circumference to the diameter, divide both sides of the equation by d.
C/d = pi
The circumference is pi times larger than the diameter of a circle.
how would you solve for 5x=13 for x
Answer:
divide by 5: x = 13/5 = 2.6
Step-by-step explanation:
Make use of the properties of the multiplicative inverse and the multiplication identity element. Multiplying both sides of the equation by the multiplicative inverse of the coefficient of x makes the result be 1x on the left side.
(1/5)(5x) = (1/5)(13)
1x = 13/5
The multiplicative identity element (1) does not change the value of what it multiplies, so this simplifies to ...
x = 13/5
_____
Effectively, we divide (both sides) by 5.

Evaluate the expression and write your answer in the form a + bi. 1) (2-6i)+(4+2i)2) (6+5i)(9-2i)3) 2/(3-9i)4) (3 − 5i)(7 − 2i)
Answer:
Step-by-step explanation:
Given the following complex numbers, we are to expressed them in the form of a+bi where a is the real part and b is the imaginary part of the complex number.
1) (2-6i)+(4+2i)
open the parenthesis
= 2-6i+4+2i
collect like terms
= 2+4-6i+2i
= 6-4i
2) (6+5i)(9-2i)
= 6(9)-6(2i)+9(5i)-5i(2i)
= 54-12i+45i-10i²
= 54+33i-10i²
In complex number i² = -1
= 54+33i-10(-1)
= 54+33i+10
= 54+10+33i
= 64+33i
3) For the complex number 2/(3-9i), we will rationalize by multiplying by the conjugate of the denominator i.e 3+9i
= 2/3-9i*3+9i/3+9i
=2(3+9i)/(3-9i)(3+9i)
= 6+18i/9-27i+27i-81i²
= 6+18i/9-81(-1)
= 6+18i/9+81
= 6+18i/90
= 6/90 + 18i/90
= 1/15+1/5 i
4) For (3 − 5i)(7 − 2i)
open the parenthesis
= 3(7)-3(2i)-7(5i)-5i(-2i)
= 21-6i-35i+10i²
= 21-6i-35i+10(-1)
= 21-41i-10
= 11-41i
Simplified form of the given expressions will be,
1). 6 - 4i
2). 64 + 33i
3). [tex]\frac{1}{15}+\frac{1}{5}i[/tex]
4). [tex]\frac{31}{53}-\frac{31}{53}i[/tex]
1). In a complex number (a + bi),
a = Real part of the complex number
bi = Imaginary part
Expression given in the question → (2 - 6i) + (4 + 2i)
Rule to solve the given expression,
"Add real part and imaginary part of two complex numbers separately"
(2 - 6i) + (4 + 2i) = (2 + 4) + (-6i + 2i)
= 6 + (-4i)
= 6 - 4i
Therefore, simplified form of the given expression will be (6 - 4i).
2). Given expression → (6 + 5i)(9 - 2i)
Rule to solve the expression → i² = -1
(6 + 5i)(9 - 2i) = 6(9 - 2i) + 5i(9 - 2i)
= 54 - 12i + 45i - 10i²
= 54 - 12i + 45i + 10 [Since, i² = -1]
= (54 + 10) + (45i - 12i)
= 64 + 33i
Therefore, simplified form of the given expression will be (64 + 33i).
3). Given expression → [tex]\frac{2}{3-9i}[/tex]
Multiply numerator and denominator with the conjugate of (3 - 9i) to convert the expression into (a + bi).
[tex]\frac{2}{3-9i}= \frac{2(3+9i)}{(3-9i)(3+9i)}[/tex]
[tex]=\frac{2(3+9i)}{3^2-(9i)^2}[/tex]
[tex]=\frac{6+18i}{9-81(-1)}[/tex]
[tex]=\frac{6+18i}{9+81}[/tex]
[tex]=\frac{6+18i}{90}[/tex]
[tex]=\frac{6(1+3i)}{90}[/tex]
[tex]=\frac{1}{15}+\frac{1}{5}i[/tex]
Therefore, simplified form of the given expression will be [tex]\frac{1}{15}+\frac{1}{5}i[/tex]
4). Given expression → [tex]\frac{(3-5i)}{(7-2i)}[/tex]
Multiply numerator and denominator with the conjugate of the denominator.
[tex]\frac{(3-5i)}{(7-2i)}=\frac{(3-5i)(7+2i)}{(7-2i)(7+2i)}[/tex]
[tex]=\frac{3(7+2i)-5i(7+2i)}{7^2-(2i)^2}[/tex]
[tex]=\frac{21+4i-35i-10i^2}{49-4(-1)}[/tex]
[tex]=\frac{21-31i+10}{53}[/tex]
[tex]=\frac{31-31i}{53}[/tex]
[tex]=\frac{31}{53}-\frac{31}{53}i[/tex]
Therefore, simplified form of the given expression will be [tex]\frac{31}{53}-\frac{31}{53}i[/tex].

EG = 5x+7 EF = 5x FG = 2x-7Point F is on line segment of EG, therefore EG = EF + FG
5x + 7 = 5x + 2x - 72x = 14x = 7Then
EG = 5*7 + 7 = 42EF = 5*7 = 35FG = 2*7 - 7 = 7The answer is 37. Use addition multiplication and must have a fraction showing the equation

Solve using Substitution Method
2x + 5y = 7
x = 2 - 4y
Answer:
x = 6y = - 1Step-by-step explanation:
2x + 5y = 7 ......... Equation 1
x = 2 - 4y .......... Equation 2
Substitute x that's equation 2 into equation 1 and solve for y
That's
2( 2 - 4y ) + 5y = 7
4 - 8y + 5y = 7
- 3y + 4 = 7
- 3y = 7 - 4
- 3y = 3
Divide both sides by - 3
y = - 1
Substitute the value of y into equation 1
That's
x = 2 - 4(-1)
x = 2 + 4
x = 6
Therefore the solutions are
x = 6y = - 1Hope this helps you

Consider the sample of n = 20 scores. Notice that they are listed in order from 2.5 to 12.0,
but that some of the scores are obscured by ***. The mean, M, of these scores is 8.0. Suppose you are asked for the sample standard deviation of these scores. Since you don't have all of them, you cannot calculate it. Which of the following is the best estimate of the sample standard deviation?
a. 9.5
b. 0.5
c. 6.4
d. 2.7
Answer:
D. 2.7
Step-by-step explanation:
Given
[tex]Mean = 8.0[/tex]
[tex]n = 20[/tex]
[tex]Range = 2.5\ to\ 12.0[/tex]
Required
Estimate the standard deviation
Since, the given data has incomplete parameters, we can apply the range rule to estimate the standard deviation;
This is done as follows;
[tex]S.D = \frac{1}{4}(Max - Min)[/tex]
In this case:
[tex]Max = 12.0[/tex]
[tex]Min = 2.5[/tex]
So:
[tex]S.D = \frac{1}{4}(Max - Min)[/tex]
[tex]S.D = \frac{1}{4}(12.0 - 2.5)[/tex]
[tex]S.D = \frac{1}{4}(9.5)[/tex]
[tex]S.D = 2.375[/tex]
From the list of given option, the closest to 2.375 is 2.7;
Hence, the best estimate is 2.7
The correct option is D. 2.7
Given that,
The mean is 8.0.the n = 20.The range is from 2.5 to 12.0The calculation is as follows:The standard deviation should be
[tex]= \frac{1}{4} (12 - 2.5)\\\\ = \frac{1}{4} (9.5)[/tex]
= 2.375
= 2.7

If km = 67 what is LM
Answer:
LM = 28 units
Step-by-step explanation:
Length of segment KL = (4x + 7) units
Length of segment LM = (5x - 12) units
Length of LM = 67 units
Since length of KM = length of KL + length of LM
By substituting the given values in the expression,
67 = (4x + 7) + (5x - 12)
67 = (4x + 5x) + (7 - 12)
67 = 9x - 5
9x = 67 + 5
x = [tex]\frac{72}{9}[/tex]
x = 8
Therefore,
LM = (5x - 12)
= (5×8) - 12
= 40 - 12
= 28
Length of segment KM is 28 units.
