How do you solve 5/6 ×20
Alex73 [517]
Ok so remember that if you had
1/2 times 3/4 that equals (1 ties 3)/(2 times 4)
just mutply top number with top number and bottom number with bottom number so

remember that 20=20/1 so
5/6 times 20/1=
5 times 20=100
6 times 1=6

5/6 times 20/1=100/6 (can be simplified to 50/3 or 16 and 2/3)

Compute the Taylor expansion of order n=2 of the function sin(xy) at x=0 and y=0
artcher [175]

Answer:

f(x, y) = Sin(x*y)

We want the second order taylor expansion around x = 0, y = 0.

This will be:

f(x,y) = f(0,0) + \frac{df(0,0)}{dx} x + \frac{df(0,0)}{dy} y + \frac{1}{2} \frac{d^2f(0,0)}{dx^2} x^2 +\frac{1}{2} \frac{d^2f(0,0)}{dy^2}y^2  + \frac{d^2f(0,0)}{dydx} x*y

So let's find all the terms:

Remember that:

\frac{dsin(ax)}{dx}  = a*cos(ax)

\frac{dcos(ax)}{dx} = -a*cos(ax)

f(0,0) = sin(0*0) = 1.

\frac{df(0,0)}{dx}*x = y*cos(0*0)*x = x*y

\frac{df(0,0)}{dy} *y = x*cos(00)*y = x*y

\frac{1}{2} \frac{d^2f(0,0)}{dx^2}*x^2 =  -\frac{1}{2}  *y^2*sin(0*0)*x^2 = 0

\frac{1}{2} \frac{d^2f(0,0)}{dy^2}*y^2 =  -\frac{1}{2}  *x^2*sin(0*0)*y^2 = 0

\frac{d^2f(0,0)}{dxdy} x*y = (cos(0*0) -x*y*sin(0*0))*x*y = x*y

Then we have that the taylor expansion of second order around x = 0 and y = 0 is:

sin(x,y) = x*y + x*y + x*y = 3*x*y

I would like to know what 1.34 as a fraction in simplest form would be
Paha777 [63]
1.34 = 1 \dfrac{34}{100} = 1 \dfrac{34 \div 2}{100 \div 2} = 1 \dfrac{17}{50}





-------- Edited to include more explanation --------------

1.34 = 1 whole 34 hundredth 

\text { 1 whole 34 hundredth written as a fraction =} 1 \dfrac{34}{100}

Then we simplified it by dividing the numerator and the denominator by 2:

1 \dfrac{34}{100}  = 1 \dfrac{34 \div 2}{100 \div 2}

34 divided by 2 will give us 17 and 100 divided by 2 will give us 50:

1 \dfrac{34 \div 2}{100 \div 2} = 1 \dfrac{17}{50}

A farmer planted corn in a square field. One side of the field measures 39 yards. What is the area of the cornfield?
alexandr402 [8]

Answer:

The area of the cornfield is 1,529 yards.

Step-by-step explanation:

In this case, since the statement indicates that it is a square field, you have to use the formula to calculate the area of a square, which is:

A=a², where:

A is the area

a is the lenght of side

The statement says that one side measures 39 yards, so this would be a, and you can replace this value on the formula:

A=39²

A=1,521

According to this, the answer is that the area of the cornfield is 1,529 yards.
