Subtract 23.4 – 8.78 =_____

Answer:

2/121

Step-by-step explanation:

Hello,

Hôpital's rule will help here.

[tex]\forall t \in \mathbb{R}^*\\\\f(t)=1-cos(2t)\text{ *** f is differentiable}\\f'(t)=2sin(2t)\\f''(t)=4cost(2t)\\f''(0)=4 \\ \\g(t)=sin^2(11t)\text{ *** g is differentiable}\\g'(t)=2sin(11t)\times 11 \times cos(11t)=2\times 11 sin(11t)cos(11t)\\\\g''(t)=2\times 11 (11cos^2(11t)-11sin^2(11t))\\g''(0)=2\times 11^2[/tex]

So the limit is 4/(2*121)=2/121

Thanks

Answer:

35y

Step-by-step explanation:

4 by the 5 power is 20

20 - 6 cause the 6 is negative but you could say 20 +-6 you'll still have to subtract

8 by the 2 power =16

then you take the plus sign and you add 20 + 16 = 36

then it says -1 for y

so you take out 1y

then that leave you with 35y

Answer:

Step-by-step explanation:

4(1)^5 - 6(1) + 8(1)^2 - 1

6 - 1 = 5

Answer: Gear 14 or 14.3

Step-by-step explanation:

Answer:

12

Step-by-step explanation:

As we can see in the picture, the bigger pentagon is a scale copy of the smaller one with a scale factor of 2. Hence, all the sides on the smaller pentagon multiplied by 2 gives us the bigger pentagon. We can find the scale factor by looking at the biggest side of the pentagon. Hope this helped, Thank you.

Answer:

[tex]x=-3[/tex]

Step-by-step explanation:

[tex]\frac{2}{3}\left(3x+9\right)=-2\left(2x+6\right)[/tex]

Expand:

[tex]\frac{2}{3} *3x+\frac{2}{3} *9=-2*2x+(-2)(6)[/tex]

[tex]2x+6=-4x-12[/tex]

Subtract 6 from both sides:

[tex]2x+6-6=-4x-12-6[/tex]

[tex]2x=-4x-18[/tex]

Add 4x to both sides:

[tex]2x+4x=-4x-18+4x[/tex]

[tex]6x=18[/tex]

Divide both sides by 6:

[tex]\frac{6x}{6}=\frac{-18}{6}\\[/tex]

[tex]x=-3[/tex]

Answer:

(10 + x) liters represents the total number of liters in the mixture

Step-by-step explanation:

Here, we want to find and expression representing the total number of liters in the solution; we proceed as follows;

The simple answer here is the sum of the liters of both solutions.

Mathematically, that would be 10 + x liters

We should understand that we do not have anything to do with the concentration of either solution and thus, the total amount in liters of both will be 10 + x liters

Given :

A particle moves in the xy plane starting from time = 0 second and position (1m, 2m) with a velocity of v=2i-4tj  .

To Find :

A. The vector position of the particle at any time t .

B. The acceleration of the particle at any time t .

Solution :

A )

Position of vector v is given by :

[tex]d=\int\limits {v} \, dt\\\\d=\int\limits {(2i-4tj)} \, dt \\\\d=(2t)i+\dfrac{4t^2}{2}j\\\\d=(2t)i+(2t^2)j[/tex]

B )

Acceleration a is given by :

[tex]a=\dfrac{dv}{dt}\\\\a=\dfrac{2i-4tj}{dt}\\\\a=\dfrac{2i}{dt}-\dfrac{4tj}{dt}\\\\a=0-4j\\\\a=-4j[/tex]

Hence , this is the required solution .

Answer:

Quantitative data

Answer:

im not sure on that one sorry

Step-by-step explanation:

Answer:

Q = 110

ST = 9

Step-by-step explanation:

Answer:

First off you have to start with what you know. You know the two planes cost 7.95 and you know the total is 24.65

Then to find the price of the stickers you subtract the 7.95 from  24.65=16.70

So your equation to start is

7.95+x=24.65

Subtract 7.95 from both sides

x=16.7-

Answer:

l-3l=3 and -3=-3

Step-by-step explanation:

The two bars mean you are finding the absolute value of a number. Absolute value is the distance from zero a number is. Since distance is always positive it basically just means take away the negative if there is one. For example,

l-7l=7 and l8l=8. So the difference is -3 is negative while l-3l is positive.

Answer:

the first tem is greater than the second term so 3>-3

Step-by-step explanation:

you have to simplify the terms first.

3 is greater than -3

Answer:

31+4x

Step-by-step explanation:

23+4(x+2)

23+4x+8

23+8=31

31+4x

hope this helps you :)

pls give me brainlest ;)

Answer:

Simplify the expression of 23+4(x+2)

We distribute 4 (x+2)

So 23+ 4×x+4×2

So 23 +4x+8

We simplify

(we calculate the numbers with the numbers and we leave 4x like that because there is no other x with which to calculate)

SO 4x+31

Answer:

Answer:

Trinomial

Step-by-step explanation:

Answer:

A. 3

Step-by-step explanation:

Given,

[tex] BC = x + 15 [/tex],

[tex] AC = 14 [/tex]

[tex] AB = x + 7 [/tex], since A, B, and C are collinear, therefore, based on the segment addition postulate:

[tex] AB + BC = AC [/tex].

Thus, substituting the values into the equation, we have:

[tex] (x + 7) + (x + 15) = 14 [/tex]

Solve for x.

[tex] x + 7 + x + 15 = 14 [/tex]

[tex] 2x + 22 = 14 [/tex]

Subtract 22 from both sides

[tex] 2x = - 8 [/tex]

Divide both sides by 2

[tex] x = -4 [/tex]

[tex] AB = x + 7 [/tex]

Plug in the value of x

[tex] AB = -4 + 7 = 3 [/tex],

Answer:

A.  (1,22), (2,44), (3,66)

B. 5 shirts were bought and the total was $110

C. 4

Step-by-step explanation:

A.

For every 1 increase in the x variable(the first number) the y variable(the second number) increases by 22

B.

The pair represents that he got 5 shirts and that he paid $110. you can check your work by seeing that if yoiu divide 110 by 5 you get the price of the t-shirt; $22

C.

If each shirt is $22 you divide $88 by $22 and get the amount of t-shirts bought; 4

Answer:

B) 10 units

Step-by-step explanation:

Area of a square is A = s², and perimeter of a square is P = 4s.

A = P + 60

s² = 4s + 60

s² − 4s − 60 = 0

(s + 6) (s − 10) = 0

s = -6 or 10

Since s can't be negative, s = 10 units.

Answer:

Yes.

Step-by-step explanation:

First, make a graph, or imagine one.

I'll be making an example graph that only goes up to 13 here.

           Age - 10    11     12    13

Height

v

6ft

5ft

4ft    

If we mark this graph with points, you will find that there is only 1 point on each age line!

           Age - 10    11     12    13

Height

v

6ft                                          *

5ft                          *       *

4ft                  *

This means the answer is yes!

Answer:

[tex]x=3\text{ or } x=-3[/tex]

Step-by-step explanation:

So we have the equation:

[tex]|6x|+3=21[/tex]

First, subtract 3 from both sides:

[tex]|6x|=18[/tex]

Definition of absolute value:

[tex]6x=18\text{ or } 6x=-18[/tex]

Divide both sides by 6 for both equations:

[tex]x=3\text{ or } x=-3[/tex]

And we're done!

Answer:

[tex]x=3[/tex] and [tex]x=-3[/tex]

Step-by-step explanation:

[tex]\left|6x\right|+3=21\\[/tex]

Subtract 3 to both sides:

[tex]\left|6x\right|+3-3=21-3\\|6x|=18[/tex]

Apply the absolute rule: If |a| = b and b > 0, a = -b or a = b.

Thus,

Case 1:

[tex]6x=18[/tex]

Divide both sides by 6:

[tex]x=3[/tex]

Case 2:

[tex]6x=-18[/tex]

Divide both sides by 6:

[tex]x=-3[/tex]

All = 13

Answer: 13

Step-by-step explanation:

26/2

Step-by-step explanation:

All u have to is subject t from that formula.

D=C( 1 + rt/100)

D/C = 1+ rt/100

D/C - 1 = rt/100

So,

When u multiply the equation by 100 and divide by r it will be as follows.

(D/C -1)100/r = t

It is the answer C.

And now to get the answer E,

we have the equation as t = (D/C-1) 100/r

First solve what inside the bracket.

D/C - 1

D/C - C/C

(D-C)/C

So when u put that to the above,

t= (D-C/C) 100/r

Now all u have to do is just multiply

t= 100(D-C) / Cr

Answer:

-6±3i√2

Step-by-step explanation:

First we need to simplify the radical here which is √-288. We can make this i√288, and then further simplify by taking out 12 giving us 12i√2. Now we have

-24±12i√2/4

From here we just divide all the terms in the numerator by 4 and get -6±3i√2
