Find the results of the given vector subtractions for u = <-8, 4> and V = <2,7>.
Answers
Answer:
see explanation
Step-by-step explanation:
- u - v
= - < - 8, 4 > - < 2, 7 > ← multiply each component of u by - 1
= < 8, - 4 > - < 2, 7 > ← subtract corresponding elements
= < 8 - 2, - 4 - 7 >
= < 6, - 11 >
----------------------------------------------------------
u - v
= < - 8, 4 > - < 2, 7 > ← subtract corresponding elements
= < - 8 - 2, 4 - 7 >
= < 6, - 3 >
-----------------------------------------------------------
v- u
= < 2, 7 > - < - 8, 4 > ← subtract corresponding elements
= < 2 - (- 8), 7 - 4 >
= < 2 + 8, 7 - 4 >
= < 10, 3 >

There are 365 days in a year and 24 hours in a day. An airport camera records for 18 hours and then automatically resets itself to start recording again how many times does the video camera reset itself in a year.
pls help
Answers
The answer is 486.6
There are 8,760 hours in a year, so 18 divided by 8,760 would = 486.6
Answer:
Step-by-step explanation:
You could do it this way.
How many hours are there in a year?
365 * 24 = 8760 hours.
This camera does not recognize days. It works on hours. Every 18 hours it resets. So
8760/18 = 486 and 2/3 times.
Obviously it cannot have 2/3 of a day. Normally you would round up, but this time you round down.
The answer is 486 times.
2/3 * 24 = 16
The camera would reset 2 hours into the next day.

Complete Question:
Michael's family was traveling to visit prospective colleges. They drove to the closest college that interested him, took a tour, and then drove to another college a little farther from home. The graph shown represents the situation.
Part A:
Enter a number in search box to complete the domain and range.
Domain ___ ≤ x ≤ ___
Range ___ ≤ y ≤ ___
Part B:
Is the statement, "the graph is continuous", true or false?
Answer:
Part A:
Domain: 0 ≤ x ≤ 5
Range: 0 ≤ y ≤ 300
Part B: True
Step-by-step Explanation:
Part A:
The domain of the function represented on the graph includes all values x plotted in the x-axis, which represents the time (hrs) travelled during the tour.
The domain is [0, 5]. The journey started at 0 mins and ends at 5 mins.
Domain can be represented as 0 ≤ x ≤ 5
The range of the function includes all values on the y-axis of the function that are plotted on the graph. The range is the set of distance covered from from during the tour.
Range is [0, 300].
This can be represented as 0 ≤ y ≤ 300.
The maximum point is at the point on the graph, when x = 5, and y = 300. This implies that it took them 5 mins to cover 300 miles during the tour.
Part B:
The graph is continuous because the line of the graph has no breaking point from start to finish.
The statement is true.

Answers
Answer:
2(x-2)(x+3)(x-8)
Step-by-step explanation:
The LCM of [tex](x+3)^2(x-2)[/tex] and [tex](x+3)(x^2-16)[/tex] is x + 3
Option A is correct
The task is to find the LCM of the expressions:
[tex](x+3)^2(x-2)[/tex] and [tex](x+3)(x^2-16)[/tex]
Note that:
[tex](x^2-16)=(x-4)(x+4)[/tex]
Therefore, the expression [tex](x+3)(x^2-16)[/tex] will become:
[tex](x+3)(x-4)(x+4)[/tex]
By considering the expressions [tex](x+3)^2(x-2)[/tex] and [tex](x+3)(x^2-16)[/tex], it is observed that x + 3 is common to both expressions.
Therefore, the LCM of [tex](x+3)^2(x-2)[/tex] and [tex](x+3)(x^2-16)[/tex] is x + 3

find the values of x and z.
Answers
Answer:
x = 2
z = 93°
Step-by-step explanation:
set the top and bottom equations equal to each other...
5x + 77 = 9x + 69, solve for x...
subtract 69 and 5x from both sides...
8 = 4x
divide both sides by 4...
x = 2
substitute 2 for x in either equation...
5(2) + 77 = 87°
subtract 87 from 180...
180° - 87° = 93°
z = 93°

-40 - 7(-7) = 9
-40 + 49 = 9

Jedi light saber: 6 ftDarth light saber: 5 ftStep-by-step explanation:
Given
a = 37b = 63c = 16Find
The length of each light saber, rounded up to the nearest foot.
Solution
The attached scale drawing shows the triangles with the angles and sides filled in.
The angle at the Jedi's hand is 2a = 2(37°) = 74°. If L represents the Jedi's light saber length, then the cosine relation is useful:
Cos = Adjacent/Hypotenuse
cos(74°) = (1.4 ft)/L
L = (1.4 ft)/cos(74°) ≈ 5.08 ft
Rounded up to the nearest foot, the Jedi's light saber is 6 ft long.
__
The angle at Darth's hand is ...
5c = 5(16°) = 80°
and the length of the opposite side is ...
b/14 = 63/14 = 4.5 . . . feet
The sine relation is useful here. If L represents Darth's light saber length, then ...
Sin = Opposite/Hypotenuse
sin(80°) = (4.5 ft)/L
L = (4.5 ft)/sin(80°) ≈ 4.57 ft
Rounded up to the nearest foot, Darth's light saber is 5 ft long.
