Answer:
Step-by-step explanation:
40a²b = 2* 2 * 2 * 5 * a² * b = 2³ * 5 * a² * b
48ab⁴ = 2 * 2 * 2 * 2 * 3 * a *b⁴ = 2⁴ * 3 * a * b⁴
LCM = 2⁴ * 3 * 5 * a² * b⁴
= 16 * 3 * 5 * a² * b⁴
= 240a²b⁴

Answer:
/_FCB
Step-by-step explanation:
As, supplementry means they add up to 180°
So a straight angle = /_DCB = 180°
So /_DCF + /_x = /_DCB
So, /_x = /_FCB
So answer = /_FCB

(b) Consider the line integral of the vector field F = (3r-y) i +j along L using the parameterization C(1)-( ,16 3t 32 16$1532 . The line integral calculated in (a) is the line integral of the parameterization given in (b).
This question is missing some parts. Here is the complete question.
Consider the oriented path which is a straight line segment L running from (0,0) to (16,16).
(a) Calculate the line inetrgal of the vector field F = (3x-y)i + xj along line L using the parameterization B(t) = (2t,2t), 0 ≤ t ≤ 8.
Enter an exact answer.
[tex]\int\limits_L {F} .\, dr =[/tex]
(b) Consider the line integral of the vector field F = (3x-y)i + xj along L using the parameterization C(t) = [tex](\frac{t^{2}-256}{48} ,\frac{t^{2}-256}{48} )[/tex], 16 ≤ t ≤ 32.
The line integral calculated in (a) is ____________ the line integral of the parameterization given in (b).
Answer: (a) [tex]\int\limits_L {F} .\, dr =[/tex] 384
(b) the same as
Step-by-step explanation: Line Integral is the integral of a function along a curve. It has many applications in Engineering and Physics.
It is calculated as the following:
[tex]\int\limits_C {F}. \, dr = \int\limits^a_b {F(r(t)) . r'(t)} \, dt[/tex]
in which (.) is the dot product and r(t) is the given line.
In this question:
(a) F = (3x-y)i + xj
r(t) = B(t) = (2t,2t)
interval [0,8] are the limits of the integral
To calculate the line integral, first substitute the values of x and y for 2t and 2t, respectively or
F(B(t)) = 3(2t)-2ti + 2tj
F(B(t)) = 4ti + 2tj
Second, first derivative of B(t):
B'(t) = (2,2)
Then, dot product between F(B(t)) and B'(t):
F(B(t))·B'(t) = 4t(2) + 8t(2)
F(B(t))·B'(t) = 12t
Now, line integral will be:
[tex]\int\limits_C {F}. \, dr = \int\limits^8_0 {12t} \, dt[/tex]
[tex]\int\limits_L {F}. \, dr = 6t^{2}[/tex]
[tex]\int\limits_L {F.} \, dr = 6(8)^{2} - 0[/tex]
[tex]\int\limits_L {F}. \, dr = 384[/tex]
Line integral for the conditions in (a) is 384
(b) same function but parameterization is C(t) = [tex](\frac{t^{2}-256}{48}, \frac{t^{2}-256}{48} )[/tex]:
F(C(t)) = [tex]\frac{t^{2}-256}{16}-\frac{t^{2}-256}{48}i+ \frac{t^{2}-256}{48}j[/tex]
F(C(t)) = [tex]\frac{2t^{2}-512}{48}i+ \frac{t^{2}-256}{48} j[/tex]
C'(t) = [tex](\frac{t}{24}, \frac{t}{24} )[/tex]
[tex]\int\limits_L {F}. \, dr = \int\limits {(\frac{t}{24})(\frac{2t^{2}-512}{48})+ (\frac{t}{24} )(\frac{t^{2}-256}{48}) } \, dt[/tex]
[tex]\int\limits_L {F} .\, dr = \int\limits^a_b {\frac{t^{3}}{384}- \frac{768t}{1152} } \, dt[/tex]
[tex]\int\limits_L {F}. \, dr = \frac{t^{4}}{1536} - \frac{768t^{2}}{2304}[/tex]
Limits are 16 and 32, so line integral will be:
[tex]\int\limits_L {F} \, dr = 384[/tex]
With the same function but different parameterization, line integral is the same.
Which expression does not have a solution of 12, if w = 4?
3 w
w + 8
4 w
16 - w
Answer:
8 w
Step-by-step explanation:
yes
Answer:
4 w
Step-by-step explanation:
So first, let's check,
Substitute 4(w=4) for each expression and then evaluate
3(4)=12
4+8=12
4(4)=16
16-4=12
16 is not equal to 12, so the answer is 4 w

Step-by-step explanation:
Mrs. Lemon’s class is planting seeds for their science projects. Each student receives a packet of flower seeds and is told to plant 1/4 of the seeds in the packet. Each student plants 6 seeds. How many seeds were in each packet?
A.
36
B.
24
C.
2
D.
10
Answer:
The answer is B
Step-by-step explanation:
If the students are asked to plant 1/4 of the packet, and they planted six seeds, you would have to multiply 4 x 6 to get a product of 24.
Please give me the correct answer.
Answer: -2
Step-by-step explanation: from the equation, -4m +6 = 14, you subtract 6 from both sides and get -4m=8, and the last step is to divide both sides by -4 and you get m=-2.

Answer:
a) linear pair angles: 1&2, 2&3, 3&4, 1&4... etc (any angles that are adjacent, or right next, to each other that add up to be 180 degrees)
b) All linear pair angles are adjacent angles but not all adjacent angles are linear pairs. So pick any linear pair angle you got because they will always be adjacent. (1&2, 2&3, 3&4, 1&4... etc)
c) vertically opposite angles: 1&3, 2&4, 5&7, 6&8, 9&11, 10&12

What is an equation of the line that passes through the point (2,3) and is parallel to
the line x + y = 4?
Step-by-step explanation:
if the line equation is in the form
y = ...
the slope is always the factor of x.
x + y = 4
y = -x + 4
so, the slope is -1.
a parallel line has the same slope.
when having a surviving point we can use the point-slope form as equation :
y - y1 = m(x - x1)
with m being the slope, and (x1, y1) being a point on the line.
so,
y - 3 = -1(x - 2)
simplified we get
y - 3 = -x + 2
y = -x + 5
that would be the slope-intercept form (+5 being the interception point on the y-axis).

Number of small packets: number of medium packets = 3:4
So how do you find like how much each one is for like 3:4
NEED HELP FAST
Answer:
3x=60
4x=80
Step-by-step explanation:
I think you've typed it wrong it must be 140 packets. All you need to do is assume 3:4 as 3x and 4x and add it
so 7x=140
x=20
3x=60

If Anna and Tamera drive 5x - 5 hours over the four days and the plan to travel 4.5
hours each day (x = 4.5), how many hours will they drive over the four days? Note
the expression 5x - 5 represents the total time traveled.
Answer:
17.5 hours
Step-by-step explanation:
5x-5 over 4 days and the plan to travel 4.5 hours each day. WE have to find how many hours will they drive each day. Now, to find the total time pu x to 4.5 in the above expression. 5(4.5)-5
= 22 * 5-5 = 17. 5 hours over the four days of traveling

The circle graphs show the percentage of men and women from Country X who consider owning a home an important part of adult life. Use the information to solve the problem.
a) What are the odds in favor of a man from Country X agreeing that owning a home is an important part of adult life?
b) What are the odds against of a man from Country X agreeing that owning a home is an important part of adult life?
Answer: a) 76 : 24
b) 24 : 76
Step-by-step explanation: Odds describe the possibility an event will occur, i.e., is the ratio of an event being successful with the chance of an event failing. It can be in favor or against:
Odds in favor is expressed as: [tex]favor=\frac{favorable}{unfavorable}[/tex];Odds against is expressed as: [tex]against=\frac{unfavorable}{favorable}[/tex];a) Odds in favor
[tex]favor=\frac{76/100}{24/100}[/tex]
[tex]favor=\frac{76}{24}[/tex]
or
favor = 76 : 24
Odds in favor of a man agreeing owning a house is an important part of adult life is 76 : 24.
b) Odds against
[tex]against=\frac{24/100}{76/100}[/tex]
[tex]against=\frac{24}{76}[/tex]
or
against = 24 : 76
Odds against of a man agrreing that owning a house is an important part of adult life is 24 : 76
