Solve for K 

\(-3K=25-7-12\)

\(-3K = 6\)

\(K = \frac{6}{-3}\)

\(K =-2\)

Guest 2 is an approximation, but not exact.  The interprolation method is better if you need exact values.

If 8^2 = x, And x^2 = y. What is y^2?

Just substitute:

(8^2)^2=y

8^4=y

y=8^4

y^2=(8^4)^2=8^8=(2^3)^8=2^24

Y^2=2^24

Since y = x^2

          y^2 = x^4        x= 8^2     (or 64)     then y^2 =  (8^2)^4 = 8^8      or   16,777,216

Expand the following:
(2+sqrt(3)) (1+sqrt(2))

(2+sqrt(3)) (1+sqrt(2)) = (2) (1) + (2) (sqrt(2)) + (sqrt(3)) (1) + (sqrt(3)) (sqrt(2)):
2+2 sqrt(2)+sqrt(3)+sqrt(3) sqrt(2)

sqrt(3) sqrt(2) = sqrt(3×2):
2+2 sqrt(2)+sqrt(3)+sqrt(3×2)

3×2  =  6:
Answer: | 2+2sqrt(2)+sqrt(3)+ sqrt(6 )

I cannot use the calculator as it's a surds question

Say I have 10 items each having a value or worth to it.

Square = 5=1

Rectangle = 5=1

Pentagon= 10/5=2/1.2=1 2/3

Hexagon = 15/5=3/1.2=2.5

Stop sign = 15/5=3/1.2=2.5

Heptagon = 20/5=4/1.2=3 1/3

Octogon =  25/5=5/1.2=4 1/6

Nonagon = 30/5=6/1.2=5

Decagon = 40/5=8/1.2=6 2/3

Circle = 60/5=12/1.2=10

This is what I would do. I would use proportionality to set the percentages up as follows: Since you want the scale of: 10:1, but you have the ratio of: 60:5. Since 60/5=12, which is: 12/10=1.2 too high. So, you reduce every ratio by dividing by 1.2. Look at what I have done above. Hope this will get you on the right track.

You CAN just use the calculator to find the answer OR you can multiply it through to get:

2 + 2sqrt2 + sqrt3 + sqrt3sqrt2     I think the first option is the easiest to get: 9.00999 ~ ~ 9

Oh, so many fractions

for example

-14/2

-21/3

-28/4

and so on.

that sucks well this sould get u better

I'm in a good mood I'm sick though I have a cold and a fever..😷

Because it's Saturday.....it doesn't work on Saturday so it can spend time with family.

LOL, dragonlance... Yes, velvet ants, also known as cow killers, do sting the tar out of you... I have quite a few of them on my bug collection... Haha, my poetry stinks... Also, I hate poetry, it makes no frickin sense... I am most always bored, they're is nothing to do around here on Saturday... Maybe I'll do Monday's school work...

The lowest values (5)  will be 1%  per your description.

The highest valeu (60 ) will be 10% per your description

Interprolate to find the others

5    10   15........................... 60    Unit value

1.....?      ?  ..........................10   percent

Example for '10'

(60 -5) / (10-1)  =   ( 60 -10)/(10-?)

55/9 = 50/(10-?)

10-? = 50 (9/55)  = 8.181818

10 - 8.181818 = ? = 1.8181 %

Example for '15'

(60-5)/(10-1) = (60-15)/(10-?)

results in ? = 2.6363 %  for 15         etc etc   

Do you need help?😊

Circunference=Dianeter X Pi

C=60 X 3.141592=188.50 Cm

188.50 X 100=188500 Cm

188,500/100=188.50 Meters, distance covered.

i think:

 circumference(perimetr) of a circle is 2pi r

2r=diametr

so: 60pi*100=18849.5559215387594308

aprox. aswer: 18849.6

Graph the first equation using the calculator.

Solve the second equation for y

y = sqrt(2/x)    and graph it.....   I think the answer is 'E'

Oh right, I see. Thankyou

then if you apply the boundary condition you get;

\(y = -2cos^2(x) + 3cos(x)\)

Not sure what you are asking....

2.30 m /  340m/s    ?     would give you how long it would take for sound to travel 2.30 m

2.30 km / 340 m/s  x 1000  would give you time for 2.3 KM     

Solve the linear equation ( dy(x))/( dx)+y(x) tan(x) = sin(2 x):
Let mu(x)  =  e^( integral tan(x) dx)  =  sec(x).
Multiply both sides by mu(x):
sec(x) ( dy(x))/( dx)+(sec(x) tan(x)) y(x)  =  sec(x) sin(2 x)
Substitute tan(x) sec(x)  =  ( dsec(x))/( dx):
sec(x) ( dy(x))/( dx)+( dsec(x))/( dx) y(x)  =  sec(x) sin(2 x)
Apply the reverse product rule g ( df)/( dx)+f ( dg)/( dx)  =  ( d)/( dx)(f g) to the left-hand side:
( d)/( dx)(sec(x) y(x))  =  sec(x) sin(2 x)
Integrate both sides with respect to x:
integral ( d)/( dx)(sec(x) y(x)) dx  =   integral sec(x) sin(2 x) dx
Evaluate the integrals:
sec(x) y(x)  =  -2 cos(x)+c_1, where c_1 is an arbitrary constant.
Divide both sides by mu(x)  =  sec(x):
Answer: | y(x)  =  cos(x) (-2 cos(x)+c_1)

 2 inches = 300 ft in the real world 

     a FOOT is 6 times more than 2 inches....right?

so   300ft x 6 times = 1800 ft     

ColdPlay and Bree how can you be bored?

The world and universe is full of mystery and life. If we have a million years we never know anything but a speck of what is there.

I was just playing with the site calculator. I am learning how to do derivatives.

Also I was reading a chemistry site on how to balance chemical equations.  

I just read a article about how winning millions in a lottery wrecked peoples lives.

Later I will check my ant farms. I put them in a deep freeze to see which ants can hibernate and which ones will just freeze to death. I do this with velvet ants. I left them in there for 3 months and with in a hour they were crawling around looking for food. I find out they not really ants. They are wingless wasps. They also sting the tar out of you too if you not careful

I am also writing a Valentine’s Day poem for my GF. I not very good at this but every time I do this I get better. My GF love these even though they are not very good yet.  So write one for your BF. You might say you not have a BF, but one day you will. So you should practice now and be ready. You not want him to throw up when you give him your first poem. hahaha   

You should not be bored. Ever.  If you are then only you can fix it. :)
