w=weeks. m=money withdrawn

5w=m

\(\frac{22}{7}\)

I think that is the fraction.

Well... Let's see...  3.141592654 (not  3.1415926353)

As a mixed number this would be \(3{141592654\over1000000000}\)

This DEFINITELY can be simplified, so let's see what we can find.

The most simplified answer is \(3{70796327\over500000000}\)

It is extremely hard to calculate we only uncoverd 1/20th of pi and that was 1 million characters

how many square inches of crust would it take to cover the bottom of a pie dish with a 15 inch diameter?​

Area of a circle: π*r²

Now, to find the radius of a circle, divide the diameter by 2.

15/2=7.5

Now, let's use the radius to find the area to cover the bottom of the pie dish.

π*7.5² = 176.7145867644258697

Round to the hundredths. 

π*7.5²≈176.71 in.²

So you would need about 176.71 square inches of crust to cover the bottom of a pie dish with a diameter of 15 inches.

The two equations we will use are:

y=5x

and

y=4x+7

Set them equal to each other.

5x=4x+7

Subtract 4x from both sides.

x=7, so they will have the same amount of candles in 7 hours.

PROOF

5(7)=4(7)+7

35=28+7

35=35

it's okay

if you want to get x by itself, there needs to be an equal sign in there somewhere.

so for example, 10 = 150/x

                        multiply both sides by x

                         10x = 150

                        divide by 10

                        x = 15

I'm with Alan on this one.

If it's a perfect S, like a sine curve for example, use the circumference of a circle formula. the radius of the circle is equal to  (the absolute value of) the amplitude of the curve.

I'm wrong!  There is an i, but you have to press the 2nd button first to see it.

No, but you can press i and that should be the imaginary sqrt(-1)

No, but you can enter the letter i.  For example the calculator accepts (1+2i)*(3+4i)

For normal distribution with mean 0 and standard deviation of 1, then 

a.  K = -0.44

b. K = 0.56

Can you provide more details of the S-shape in question?

Pythagoras'stheorem says the square on the hypotenuse of a right triangle is equal to the sum of the squares on the two adjacent sides.

.

Use / or hit the divide button on the calculator

The angle, A, made between the horizontal and a line of slope m is given by A = tan^-1(m) so the angle between your two lines is given by  tan^-1(2) - tan^-1(1/2)                (approx 37°)

.

f1=-4x^-5

=-4/x^5

Solve for x:
x^2-x+30 = 0

Subtract 30 from both sides:
x^2-x = -30

Add 1/4 to both sides:
x^2-x+1/4 = -119/4

Write the left hand side as a square:
(x-1/2)^2 = -119/4

Take the square root of both sides:
x-1/2 = (i sqrt(119))/2 or x-1/2 = 1/2 (-i) sqrt(119)

Add 1/2 to both sides:
x = 1/2+(i sqrt(119))/2 or x-1/2 = 1/2 (-i) sqrt(119)

Add 1/2 to both sides:
Answer: |  x = 1/2+(i sqrt(119))/2    or     x = 1/2-(i sqrt(119))/2

The answer is x=1/(2^6)

                       x=1/64

you use the forward slash, /. or u can click the devide symble

More information is needed.

In isolation this makes no sense.

I think O can be any constant :/

a number that is so Long that it couldn't get calculated yet, not even by machines . It starts with 3.14159265359!
