Write an equation of the line that passes through (5, −1) and is perpendicular to the line y=12x−1.
Step-by-step explanation:
solution
let,A(5,-1)
given
y=12x-1
or, y = 12 × x + (-1)
comparing it with y=mx+c
we get
x=1
y = c = -1
now
A(5,-1) and B(1,-1)
equation of line is,
(y-y1)/(x-x1) = (y2-y1)/(x2-x1)
or, (y+1)/(x-5) = (-1+1)/(1-5)
or, (y+1)/(x-5) = 0/-4
cross multiply
-4y-4 = 0
or, 0=4y+4
or, 4y+4=0 is the required eqn
I think this is the process and answer too.
I hope this helps you
The employment status (employed or unemployed) of each individual in the U.S. workforce is a set of data that is of interest to economists, businesspeople, and sociologists. To obtain information about the employment status of the workforce, the U.S. Bureau of the Census conducts what is known as the Current Population Survey. Each month interviewers visit about 59,000 of the 98 million households in the United States and question the occupants over 14 years of age about their employment status. Their responses enable the Bureau of the Census to estimate the percentage of people in the labor force who are unemployed (the unemployment rate).
Question Completion:
(a) Identify the experimental unit.
(b) Define the population of interest to the Census Bureau.
(c) Identify the sample.
(d) What variable is being measured? Is it quantitative or qualitative?
(e) Describe the statistical inference that the economists intend to make.
Answer:
a. The experimental unit is the households visited.
b. The population of interest to the Census Bureau is all US-based individuals aged 14 and above.
c. The sample is 59,000 households.
d. The variable under measure is quantitative (percentage estimate of people in the labor force who are unemployed).
e. The economists want to make a statistical inference of the unemployed population based on the sample data analysis that they conduct.
Step-by-step explanation:
a) Data and Calculation:
Population of interest = 98 million households
Sample from population = 59,000 households
b) The unemployment rate is the percentage of the total workforce of a country that is unemployed and who may be actively seeking employment at a particular period. This implies that the unemployment rate may include persons who are active members of the workforce but may be underemployed.

In RST , if RT ST , mR = (9x + 2)°, mS = (13x – 18)°, and mT = (17x + 1)°, find x and the
measure of each angle.
Answer:
x = 5
<R = 47 degrees
<S = 47 degrees
<T = 86 degrees
Step-by-step explanation:
The sum of angles in a triangle is 180degrees
Given triangle RST
<R + <S + <T = 180
9x + 2 + 13x - 18 + 17x +1 = 180
39x - 15 = 180
39x = 180 + 15
39x = 195
x = 195/39
x = 5
Get <R
<R = 9x + 2
<R = 9(5) + 2
<R = 47 degrees
Get <S
<S = 13x-18
<S = 13(5) - 18
<S = 65-18
<S = 47 degrees
Get <T
<T = 17x + 1
<T = 17(5)+1
<T = 85+1
<T = 86 degrees

3/4 + -3/8 + -1/4=?
Evaluate the expression
Answer: -1/8
Step-by-step explanation:
3/4 + -3/8 + -1/4
Find the LCM of 4, 8, and 4
That's 8 so you make an equivalent fraction for all fractions so the denominator is 8.
3/4 = 6/8
-3/8 = -3/8
-1/4 = -4/8
Now the expression looks like this:
6/8 + - 3/8 + -4/8
6/8 - 3/8 - 4/8
6/8 - 7/8
-1/8

a plane, initially traveling 150 mi/hr 100 east of north, suddenly enters a region where the wind is blowing at 50 mi/hr from the southwest. What is the plane's resultant direction?
Answer:
Velocity of plane is 100 mi/hr along northeast direction
Step-by-step explanation:
From the question it is given that Initial velocity of plane is 150 mi/hr along east north direction and wind is blowing at 50 mi/hr along southwest direction
since the velocity of wind and plane is exactly opposite
⇒ relative velocity of plane with respect to wind is given by
[tex]v_r_e_l = v_p - v_w[/tex] where [tex]v_p[/tex] is the velocity of plane = 150mi/hr and [tex]v_w[/tex] = velocity of wind = 50 mi/hr
Therefore, [tex]v_r_e_l = v_p - v_w[/tex] = [tex]v_r_e_l = 150 - 50 = 100 mi/hr[/tex] alond northwest direction
Therefore, velocity of plane is 100 mi/hr along northeast direction
By working with the velocity vectors, we will find that the direction of motion of the plane is 28.7 south of east.
Working with the velocity vectors:
First, we need to define our coordinate axis, I will define the x-axis as the east and the y-axis as the north.
We know that the plane travels at 150 mi/hr at 100° east of north, notice that if we measure from the positive x-axis, this is equivalent to an angle of -10°.
Then the x-component of the velocity is: 150mi/hr*cos(-10°) = 147.7 mi/hrThe y-component of the velocity is: 150mi/hr*sin(-10°) = -26 mi/hr.
So the vector is:
V = < 147.7 mi/hr, -26 mi/hr >
Now we know that the wind blowing at 50mi/hr at southwest, exactly southwest would be at an angle of 225°, so the components of the vector are:
x-component: 50mi/hr*cos(225°) = -35.4 mi/hry-component: 50mi/hr*sin(225°) = -35.4 mi/hr.So the vector is:
W = < -35.4 mi/hr, -35.4 mi/hr>
The sum of the vectors gives the total velocity of the plane in the wind, we will get:
V + W = < 147.7 mi/hr -35.4 mi/hr , -26 mi/hr -35.4 mi/hr >
V + W = <112.3 mi/hr, -61.4 mi/hr>
The direction of a vector <x, y> is given by:
θ = Atan(y/x)
Then in this case the direction of the plane is:
θ = Atan(-61.4 mi/hr/112.3 mi/hr) = -28.7°
So the direction of the plane is 28.7° south of east.

Answer:
23 bags
Step-by-step explanation:
Answer: 23
Step by step explanation:
In the figure, solve for x and y.
Answer:
y=124°
x=67°
Step-by-step explanation:
For the triangle on the right
180-74-50=56°
then y= 180-56=124°
For the triangle on the middle (that small triangle)
180-85(Head opposite angles)-50=45°
So
x=180-45-68=67°

A machine cell uses 204 pounds of a certain material each day. Material is transported in vats that hold 34 pounds each. Cycle time for the vats is about 2.25 hours. The manager has assigned an inefficiency factor of .17 to the cell. The plant operates on an eight-hour day. How many vats will be used
Answer: 2 Vats will be used
Step-by-step explanation:
using the formula below, the ideal number of Kanban cards can be calculated;
N = (DT × ( 1 + X)) / C
where N is total number of container,
D is panned usage rate of using work Centre
T is Average waiting time for replenishment of parts plus average production for a container of parts,
X is policy variable set by management that reflects possible inefficiency in the system ,
C is capacity of standard container.
Now, in the question, we were given that;
D = 204 pounds per day = 204 / 8hrs = 25.5 pounds/hr { The plant operates on an eight-hour day}
T = 2.25 hrs
X = 0.17
C = 34 pounds each
we substitute
N = (25.5×2.25 × ( 1 + 0.17)) / 34
N = 67.12876 / 34
N = 1.974375 ≈ 2 Vats
Therefore 2 Vats will be used.
