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

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

Answer:

X=58/3=19 1/3

Step-by-step explanation:

32-x=0.4(2x-7)

32-x=0.8x-2.8

32-x-0.8=-2.8

32-.18x=-2.8

-1.8x=-2.8

-1.8x=-34.8

x=58/3

3/8=0.375

11/16=0.6875

0.375+0.6875=1.0625

The base of the model merry-go-round is 450in², and the actual merry-go-round's base is 400 times larger.

Therefore the base of the actual merry-go-round is 180,000in². However, the question asks for the answer in square feet.

180,000in² in squared feet is:

1,250ft² (your final answer)

Answer:

B (3x^2 + 4x - 6)

Step-by-step explanation:

Correct on EDGE

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

Step-by-step explanation:

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.

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.

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:

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

Step-by-step explanation:

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

Answer:is there a picture I can refer to?

Step-by-step explanation:

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).

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

4x=80

Answer:

Step-by-step explanation:

u = 2v

(2v)² = v² + 3

4v² - v² = 3

3v² = 3 ⇒ v = 1 and u = 2
