6 3/8 / 2 1/16,

This reduces to:

34/11=3.09090909.............. Bye!.

how do you write 159995 in scientific notation,

How about=1.59995 X 10^5

3 over the square root 12

3/sqrt(12)

3/3.464...... =.8660254.......etc.

x^2-18x+81=-289

(x -9)^2=-289

x=9 - 17i  and  x=9 + 17i

x+12=-24

x=-24-12

x=-36

Converting to decimal value, we have :

[220 + 47/60]°  = about 220.833°

csc [220.833°] =  about -1.5309

26,525,285,981,219,105,863,630,848,000,000  [about 26.525 nontillion ]

I'm not great at Physics, but I think we can use this equation to solve this:

[v_f ]²  = [v_i]²  + 2ad       where v_f is the final velocity, v_i is the intal velocity, a is the acceleration and d is the displacement of the object.......so we have

[v_f]²  =  (9.6m's)² + 2(4.2m/s²)(450m)

[v_f]² = 3872.16m²/s²     taking the square root of both sides we have

v_f = about 62.23 m/s

x+12= -24

Move 12 to the right hand side and change it from + to -, thus:

x=-24-12, now just add the two numbers and - stays in front of the number,

x=-36

You can use \(v^2=u^2+2as\)

v = final velocity

u = initial velocity

a = acceleration

s = distance

\(v=\sqrt{9.6^2+2*4.2*450}=62.2 m/s\)

What is the range of y = sin θ ?

{y element R : -1<=y<=1}
(assuming a function from reals to reals)

Expand

\(\frac{(1-2a)^2}{6}-a^2- \frac{14-a^7}{3} \)

Find common denominator. it is 6

\(-\frac{2(-a^7+14)}{6}-\frac{6a^2}{6}+\frac{(-2a+1)^2}{6}\)

\(\frac{-2(-a^7+14)-6a^2+(-2a+1)^2}{6} \)

Expand this part

\( (-2a+1)^2\)

to this

\(4a^2-4a+1 \)

then expand this

\(-2(-a^7+14)\)

to this

\(2a^7-28 \)

then combine the parts

\(2a^7-6a^2+4a^2-4a+1-28 \)

simplefy it and put it over the 6 and make equal to 0

\(\frac{2a^7-2a^2-4a-27}{6} =0\)

change to this

\(\frac{2a^7-2a^2-4a}{6} =\frac{27}{6}\)

change to this

\(2a^7-2a^2-4a =27 \)

I out of time. Next post I solve it (or try to).

i think you have:

3256-[5]x5.33    if so, we have

3256 - 26.65 =

3229.35

Maybe someone here knows better than me, but I don't believe our calculator will do this.....here's one that will :

Kind of late reply as I havn't been on but that's what I ended up doing so your answer agrees with me -> The M.C consists of 4 states (0,0) , (1,0) , (0,1) , (1,1) and then you find the transition probabilities for each state using what you've given.

Are you talking about the calculator on this site? If yes, then that means press the(=) button.

 A trillion in ALL English-speaking countries is pretty well agreed on to be 10^12.

That's what the "Guest" meant above when he/she wrote 1.7 X 12=1.7 X 10^12.

Thanks lad

The number π is a mathematical constant, the ratio of a circle's circumference to its diameter, commonly approximated as 3.14159. It has been represented by the Greek letter "π" since the mid-18th century, though it is also sometimes spelled out as "pi"

√85 is between what two consecutive whole numbers?

Ann is X years old. David is 3 years younger than ann. Ken is twice as old as Ann. The total of their ages is 25. How old is ann?

\(\text{Ann } = x \\ \text{David } = x - 3\\ \text{Ken } = 2 \cdot x \\ \text{Ann + David + Ken } = 25\\ \begin{array}{rcl} x + (x-3) + 2 \cdot x &=& 25\\ 4x - 3 &=& 25\\ 4x &=& 28 \\ \mathbf{x} & \mathbf{=} & \mathbf{7} \end{array}\\ \text{Ann is 7 years old } \\ \text{David is 4 years old }\\ \text{Ken is 14 years old}\)

If you wnat to know if 1/11 is greater than 1/12, just subtract them thus:

1/11 -1/12=1/132, so 1/11 is greater 1/12 by 1/132, because,

1/132 +1/12=1/11

What number is 27% of 9.14?

what is 1.7 trillion divided by 525600

(1.7 X 12) / 525600=3,234,398.78234

If you mean the magnitude of the vector in terms of the x, y and z components, then it is \(r=\sqrt{x^2+y^2+z^2}\)
