Answer:
u, AB6.4arctangent51°MN has the opposite direction of NMa ray has infinite length; a vector has finite lengthStep-by-step explanation:
1. The problem preamble gives you the two ways to name the vector. You can use either its name, or the two end points. (The starting point is named first, as it is with a ray.)
The vector shown can be referred to by the names ...
u or AB
__
2. The right triangle has legs 4 and 5, so the length is ...
length = √(4² +5²) = √41
length ≈ 6.4
__
3. Typically, you're given the leg lengths. The ratio of these is the tangent of the angle. The angle can be found using the inverse tangent function.
__
4. The tangent of the angle is the slope of the vector:
tan(A) = 5/4
A = arctan(5/4) ≈ 51°
__
5. The first letter named is the starting point of the vector. Vector MN starts at point M and ends at point N. Vector NM starts at N and ends at M. The directions of the two vectors are opposites.
__
6. A ray is like a vector of infinite length. The name of a ray includes a point on the ray. The name of a vector includes both end points. It is of finite length.
_____
Additional comment
A lot of math is invented to describe how things work in the real world. A vector is often used to represent velocity or force and other things that can be described by a magnitude and direction in the real world. A ray is more often used in problems in geometry, where that abstract concept serves a useful purpose.

Washer and dryer cost $784 combined. The washer cost $66 less than the dryer. What is the cost of the dryer.
Answer:
$425
Step-by-step explanation:
Let the dryer cost x
and the dish washer cost y
x+y=784-----------1
y=x-66-------------2
put the value of y=x-66 in 1
x+x-66=784
2x= 784+66
2x=850
x=850/2
x=425
Hence the dryer cost $425
Parker drove a total distance of 4 and 1 over 2 miles during the months of June and July. If Parker only drove 1 over 8 of a mile every day, which expression shows the number of days he went driving? 4 and 1 over 2 ⋅
Answer:
36 days
Step-by-step explanation:
Total distance driven = 4 1/2 miles = 9/2 miles
Months of June and July ;
Miles driven per day = 1/8
Number of days Parker went driving :
Total miles driven / miles driven per day
9/2 miles ÷ 1/8 miles
9 /2 * 8 /1
(9 * 8) / (2 * 1)
72 / 2
= 36 days
Hence, Parker drove for 36 days
Norma has an A-frame cabin. The back is shown below. How many square feet of paint will she need to cover the back of the cabin? please help
Answer:
191.25 square feet
Step-by-step explanation:
The question is basically asking for the area.
The area of a triangle is base times height divided by 2.
So...
15 * 25 1/2 = 382.5
382.5 divided by 2 = 191.25 square feet.
Hope this helps!

Answer:
g(x) = (5x +26)/(x+5)
Step-by-step explanation:
To translate the function right h units and up k units, the transformation is ...
f(x -h) +k
You want h=-4 (4 units left) and k=-1 (1 unit down). So, the translated function is ...
[tex]f(x+4)-1=\dfrac{6(x+4)+7}{(x+4)+1}-1\\\\=\dfrac{6x+31}{x+5}-1=\dfrac{6x+31-(x+5)}{x+5}\\\\=\dfrac{5x+26}{x+5}[/tex]
The translated function is ...
g(x) = (5x +26)/(x+5)
__
The original function is in red with asymptotes shown in orange. The translated function is in purple with the asymptotes shown in blue. You can see that the function has been moved 4 left and 1 down.
Answer this real-world question
Xavier had $100 in his lunch account. He spends $6 for lunch each day. Zack has $160 in his lunch account. He spends $10 each day. After how many days will the boys have the same amount of money in their accounts? How much money will they each have on that day?
Answer:
After 15 days they'll both have $10
Explanation:
100 (Xavier's total)- 6x (6 dollars every day) = 160 (Zach's total amount) -10x (10 dollars every day)
[tex]100-6x=160-10x\\[/tex]
+10x on both sides
[tex]100+4x=160[/tex]
-100 on both sides
[tex]4x=60[/tex]
/4 on both sides
[tex]x=15[/tex]

2. It takes Jacob 30 minutes to wash the car by himself if
takes Malochi 25 minutes to wash the car by himself if
they work together, how long would it take for them to
wash the car together?
Let x represent the number of hours that he spent washing cars.
Let y represent the number of hours that he spent landscaping.
In a week, he can work no more than 19 total hours. This means that
x + y ≤ 19- - - - - - - - - - - -1
Jacob is working two summer jobs, making $10 per hour washing cars and making $8 per hour landscaping. He must earn at least $170. This means that
10x + 8y ≥ 170 - - - - - - - - - -2
If Jacob worked 4 hours landscaping, it means that
x + 4 ≤ 19 x ≤ 19 - 4 x ≤ 15
Also, 10x + 8 × 4 ≥ 170 10x + 32 ≥ 170
10x ≥ 170 - 32 10x ≥ 138
10x ≥ 138/10 x ≥ 13.8
The minimum number of hours is 14
Which inequality is true if n = 81?
F 3n < 84
G n − 29 < 53
H 2n < 162
J n + 5 < 76
Answer:
G n - 29 < 53
Step-by-step explanation:
Replace n with 81 so it becomes
81 - 29 < 53
If you solve, 81 - 29 would be 52
Then you have
52 < 53
This is true since 53 is greater than 52

Which of these strategies would eliminate a variable in the system of equations? 5x+8y=-1 5x -8=-7
Answer:
To eliminate a variable in the system, we will have to subtract both expressions from each other
Step-by-step explanation:
Given the equations
5x+8y=-1
5x -8y=-7
To eliminate a variable in the system, we will have to subtract both expressions from each other
5x - 5x +8y-(-8y) = 1-(-7)
0 + 16y = 8
16y = 8
You can see that the variable x has been eliminated by simply subtracting both equations
y = 8/16
y = 1/2

solve the equation y = 200 - 5(x + 37) for x if y = 360.
Answer:
x= -35.153846
Step-by-step explanation:
360=200-5(x+37)
360=195(x+37)
360=195x+7215
360-7215=195x+7215-7215
-6855=195x
-6855/195=195x/195
-35.1538461538=x
-35.153846=x

A truck has a force of 2000 newtons and is moving 10 miles per hour. How much mass does the truck have?
Answer:
Force= Mass×Accelaraion
F=m×a
But as The unit of accelaration is given miles per hour and the SI is meters per second sqaure we have to convert 10mph to m/s²
Thus, we have 10mph = 4.47 meters per second square. (i converted using scientific calculator)
So now we have,
2000N= m×4.47m/s²
= 2000/4.47m/s²=m
= 447.42
Thus the mass of the object is 447.42 (i am not sure of units)
Answer:
Force= Mass×Accelaraion
F=m×a
The unit of accelaration is given miles per hour and the SI is meters per second sqaure we have to convert 10mph to m/s²
we have 10mph = 4.47 meters per second square
2000N= m×4.47m/s²
= 2000/4.47m/s²=m
= 447.42

Please help I need by 9:00 am
Answer:
here!
Step-by-step explanation:
so graphing lines are pretty hard but this one is fairly simple. here the slope formula format is y=mx+b
m being the slope
and b being the y-intercept
so as you can see your equation has no slope meaning your line is just going to be straight
and then if you take a look to find the only other thing your equation has in it is a 6 as the y-intercept meaning in order to graph this find where 6 is on the y-axis (the vertical line on the side) and draw a line going horizontal and put a dot or a point on (0,6) to mark that you have found the y-intercept and that this is the only known point on your line graph so far with the information given. i hope this makes sense, and have a great day!
