Step-by-step explanation:

The average rate of change of a continuous function,

Additional Notes:

Note that this question is steered towards deriving the derivative  

f

'

)

from first principles, as the definition of the derivative is:

f

(

)

=

lim

h

→

0

f

(

x

h

)

−

f

(

h

This is the function we had in [1], so as we take the limit as  

h

→

0

we get the derivative  

f

for any  

x

, This:

Answer:

(1-sin(x))/(1+cos(x)) = (csc(x) - 1)(csc(x) - cot(x))

Step-by-step explanation:

(1 - sin(x)) / (1+cos(x)) =

[ (1-sin(x))/ (1+cos(x)) ] * (1-cos(x))/(1-cos(x)) =

(1-sin(x))(1-cos(x)) / (1 - cos^2(x)) =  

(1-sin(x))(1-cos(x)) / (sin^2(x)) =

[ (1-sin(x)) / sin(x) ] * [ (1 - cos(x)) / sin(x) ] =

(csc(x) - 1)(csc(x) - cot(x))

Answer:

Answer:

y=2x+7

Step-by-step explanation:

find (-5,-3)

use the slope to find the y intercept

intercept is (0,7)

use formula y=mx+b to plug in numbers

(slope is m and y intercept is b)

y=mx+b

y=2x+7

Answer:

x = 30

Step-by-step explanation:

The two angles are congruent so they have the same value

3x-5 = x+55

Subtract x from each side

3x-5 -x = x+55-x

2x-5 = 55

Add 5 to each side

2x-5+5 = 55+5

2x= 60

Divide each side by 2

2x/2 = 60/2

x = 30

You would get

x=40

Your answer

Answer:

The answer is 5

Step-by-step explanation:

Since we already know what x we can just substitute it.

5(8)-2y=30

5 times 8 is 40

40-2y=30

Subtract 40 on both sides:

-2y=-10

Divide -2 on both sides:

y=5

Answer:

g=11

Step-by-step explanation:

What I did was Isolate the variable by dividing each side by factors that don't contain the variable.

Set the equation equal to zero and factor the left side.

The factor answer would be 2(−g+11)=0

Answer: A.

Step-by-step explanation: There are a few outliers in A which would generally distort the shape of a dot plot where a majority would be clustered around the mean, and the points off to the side would fall far away from the mean making it skewed right in this situation.

Answer:

294

Step-by-step explanation:

since the area is 7^3, the cube's side length is 7

SA = 6*7^2 = 294

Answer:

[tex]15.2~mph[/tex]

Step-by-step explanation:

Let the time flown by the flying carpet be [tex]t[/tex]. Then, we have that [tex](2.4)/t=(1.4)/t+2*4[/tex].

We multiply both sides of the equation by [tex]t[/tex] to get [tex]2.4=1.4+8t[/tex].

We subtract [tex]1.4[/tex] from both sides to get [tex]1=8t[/tex].

We divide both sides of the equation by [tex]t=1/8[/tex].

We know that the speed of the flying carpet in still wind is the average of the rates of the speed of the flying carpet with the wind and against the wind.

The speed with wind is [tex](2.4)/(1/8)=19.2[/tex]mph.

The speed against wind is [tex](1.4)/(1/8)=11.2[/tex]mph.

The speed in still wind is [tex](19.2+11.2)/2=(30.4)/2=15.2[/tex].

Therefore, the answer is [tex]\boxed{15.2~mph}[/tex] and we're done!

The speed of the flying carpet in still air is 15.2 mph

Let x represent the speed of the flying carpet in still air, and t represent the time.

Speed = distance/time

Since the wind speed is 4 mph, hence:

When flying with the wind:

x + 4 mph = 2.4/t     (1)

When flying against the wind:

x - 4 mph = 1.4/t     (2)

Dividing equation 1 by 2 gives:

(x + 4) / (x - 4) = 2.4/1.4

1.4x + 5.6 = 2.4x - 9.6

x = 15.2 mph

The speed of the flying carpet in still air is 15.2 mph

Answer:

For complex numbers,

a + bi and a - bi

they have the interesting property that if you add them you get the real number 2a

and if you multiply them , because of the difference of square pattern, you get a^2 - b^2 i^2

But since i^2 = -1, we end up with a real number as a product.

e.g. 6 - 5i and 6 + 5i are conjugates of each other

sum = 6-5i + 6+5i = 12

product = 36 - 25i^2

= 36 -(-25) = 61

Your question is even easier, since the denominator is a monomial instead of a binomial, so we just have to multiply by i/i

Also I believe, according to the answer, that you have a typo, and you meant

(-5+i)/(2i)

= (-5+i)/(2i) *i/i

= (-5i + i^2)/2i^2)

= (-5i +i^2)/-2

= (-5i - 1)/-2

= (1 + 5i)/2 or they way they have it: 1/2 + 5i/2

ANSWER:

     43

Explanation:

A : B : C

     4 : 3  

          5 : 2

A × B → 4 × 5 = 20

B × B → 3 × 5 = 15

B × C → 3 × 2 = 6

  A : B : C

 20 : 15 : 6

B = 15 = 30

what of teams A and C together?

 If 15 = 30games, what about 26games?

Cross multiply.

   15 × 26          =13

      30

So, games won by Team B + games won by Teams A and C

        30games + 13games

               =43games.

Answer:

15

Step-by-step explanation:

Answer: 15

Step-by-step explanation:

you would have to find the square root of 225 and this is 15 so if you do 15x15 you will get 225

and if you need to find the perimeter you add up all the sides

15x4=60

The perimeter of a square is 60

1 side length of a square: 15
