Answer:
If we know that [tex]x = 1[/tex] and [tex]y = 9[/tex], the value of [tex]g[/tex] is 19.
Step-by-step explanation:
Let [tex]C(x,y) =(-2,12)[/tex] and [tex]D(x,y) =(4,6)[/tex], from Analytical Geometry and Linear Algebra we have that midpoint of CD is determined by:
[tex]M(x,y) = \frac{1}{2}\cdot C(x,y)+\frac{1}{2}\cdot D(x,y)[/tex] (Eq. 1)
[tex]M(x,y) = \frac{1}{2}\cdot (-2,12)+\frac{1}{2}\cdot (4,6)[/tex]
[tex]M(x,y) = (-1,6)+(2,3)[/tex]
[tex]M(x,y) =(-1+2,6+3)[/tex]
[tex]M(x,y)= (1,9)[/tex]
If we know that [tex]x = 1[/tex] and [tex]y = 9[/tex], the value of [tex]g[/tex] is 19.
1. What is the slope intercept form for -3, and (4,2) SIMPLIFIED??
2. What is the slope intercept form for -1/2 and (-5,6) SIMPLIFIED???
Answer:
Step-by-step explanation:
1. y - 2 = -3(x - 4)
y - 2 = -3x + 12
y = -3x + 14
2. y - 6 = -1/2(x + 5)
y - 6 = -1/2x - 5/2
y - 12/2= -1/2x - 5/2
y = -1/2x + 7/2

Plzzzzzz helpppp!!!!! What is an equation of the line that passes through the point (4,2) and is perpendicular to the line 4x+3y=21
The line which is perpendicular to the line 4x + 3y = 21 is y = x + 1.
What are lines and their slopes?We know lines have various types of equations,
The general type is Ax + By + c = 0, and the equation of a line in
The slope-intercept form is y = mx + b.
Where slope = m and b = y-intercept.
the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.
An equation of a line is given which is 4x + 3y = 21 or 3y = - 4x + 21.
So, The line has a slope(m) = - 4.
∴ The line perpendicular to this line has a slope of (1/4) as perpendicular lines have slopes that are negative reciprocals of each other and it is passing through the points (4, 2).
∴ 2 = (1/4)(4) + b.
b = 1.
∴ y = x + 1 is the line.

Why should you not choose a point on the line to find the direction of shading in an inequality?
Answer:
Because we know for a fact that the line has a correct answer. Plus, if you choose a point on the line then it will not give you the visual side of which is correct and which is wrong.
Step-by-step explanation:
If you choose a point on the line then it will not give you the visual side of inequality. Therefore, choose the interval.
What are inequalities?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
Unless you are graphing a vertical line the sign of the inequality will let you know which half-plane to shade. If the symbol ≥ or > is used, shade above the line. If the symbol ≤ or < is used shade below the line. For a vertical line, larger solutions are to the right and smaller solutions are to the left.

1. In the office, there is a filing cabinet that is 1 foot wide, 3 feet deep and 3
feet tall. You have hundreds of file folders to put into this cabinet.
Assuming that each folder is 12 inches wide, 1 inch thick, and 9 inches
tall, how many folders can you fit into this cabinet? (Draw a picture!)
Answer:
the answer is 144 folders
Step-by-step explanation:
you have to convert the ft of the file cabinet to inches. so the cabinet is 12 in wide, 36 in deep and 36 in tall. the volume of it is 15,552 cu in. each folder is 108 cu in. divide 15,552 by 108 = 144 folders can fit in the cabinet. sorry my pic is messy.

Wave erosion causes a certain coastline to recede at a rate of 3 centimeters each year. This occurs uninterrupted for a period of 8 years. How far will the coastline recede in 8 years?
Answer:
24 cm
Step-by-step explanation:
Given that:
Rate at which coastline recedes per year = 3cm
Recede rate occurred uninterrupted for 8 years ; how far will the coastline recede in 8 years :
3cm per year for 8 years
Hence,
3cm * 8
= 24 cm
The coastline would have recede for 24cm in 8 years

Keisha is reading a 325-page book at a rate of 25 pages per day. Use a point-slope equation to determine wheatger she will finish reading the book in 10 days
Answer:
she can't finish reading the book in 10 days
Step-by-step explanation:
Given that:
Number of pages = 325
Number of pages read per day= 25
Using the linear relation:
y = mx + c
y = number of pages left
m = reading rate ; c = initial number of pages
y = - 25x + 325
Point slope relation :
y - y1 = m(x - x1)
m = slope
We can factorise the equation to the point slope form:
y - 325 = 25(0 - 10)
y - 325 = 0 - 250
y - 325 = - 250
y = - 250 + 325
y = 75
Hence, number of pages left after 10 days = 75, thus she can't finish reading the book in 10 days

37% of women consider themselves fans of professional baseball. you randomly select six women and ask each if she considers herself a fan of professional baseball. Complete parts (a) through (d) below. (a) find the mean of the binomial distribution. (b) find the variance of the binomial distribution. (c) Find the standard deviation of the binomial distribution
Answer:
(a) 2.22
(b) 1.3986
(c) 1.183
Step-by-step explanation:
Let X denote the number of women who consider themselves fans of professional baseball.
The proportion of women who consider themselves fans of professional baseball is, p = 0.37.
A random sample of n = 6 women are selected and each was asked if she considers herself a fan of professional baseball.
Each woman's reply is independent of the others.
The random variable X thus follows a binomial distribution with parameters n = 6 and p = 0.37.
(a)
Compute the mean of the binomial distribution as follows:
[tex]\text{Mean}=np=6\times 0.37=2.22[/tex]
(b)
Compute the variance of the binomial distribution as follows:
[tex]\text{Variance}=np(1-p)=6\times 0.37\times (1-0.37)=1.3986[/tex]
(c)
Compute the standard deviation of the binomial distribution as follows:
[tex]\text{Standard Deviation}=\sqrt{np(1-p)}=\sqrt{6\times 0.37\times (1-0.37)}=1.183[/tex]

Compare 6.23 * 10^14 and 8.912 * 10^12
Answer:
623,000,000,000,000 > 8,912,000,000,000
Step-by-step explanation:
8.912·10^12
The exponent is 12, making it 10 to the power of 12. As the exponent is positive, the solution is a number greater than the origin or base number. To find our answer, we move the decimal to the right 12 time(s):
8.912 -> 8,912,000,000,000
6.23·10^14
The exponent is 14, making it 10 to the power of 14. As the exponent is positive, the solution is a number greater than the origin or base number. To find our answer, we move the decimal to the right 14 time(s):
6.23 -> 623,000,000,000,000

Answer:
The maintenance electrician takes 287.555555566667 hours to to rewire all the motors
Step-by-step explanation:
1. Calculate all of the minutes for all the numbers.
It takes you 26.6666667 minutes to rewire 2/3 of a motor.
It takes you 160 minutes to rewire 4 motors.
It takes you 266.666667 to rewire 6 2/3 motors
It takes you 7,200 minutes to rewire 180 motors
It takes you 9,600 minutes to rewire 240 motors
2. Add all of the minutes together.
26.666667 + 160 + 266.666667 + 7,200 + 9,600 = 17253.333334
It takes you 17253.333334 minutes to rewire 431.333333 motors
3. Convert minutes to hours
17253.333334/60 = 287.555555566667
It takes you 287.555555566667 hours to rewire all the motors
