Write the ratio as a fraction in simplest form: 4ft : 2.4ft
Gekata [30.6K]
The answer would be 12:7 . You have to change feet into inches and calculate it from there . Doing that would get you 48:28 and if you put it into simplest form it'd be 12:7 dividing both by 4.

What is the quotient?<br> 212,960 - 1000<br> o<br> 2.1296<br> 21.296<br> 212.96<br> 0<br> 2129.6
Nonamiya [84]

The quotient is 212.96.

Solution:

Given expression is \frac{212,960}{1000}.

Divide the given expression to find the quotient.

Decimal rule when numerator is divided by 10, 100, 1000, 10000 etc..

  • If you have one zero in the divisor (10), then the decimal point will move 1 place to the left of the last digit.
  • If you have two zeros in the divisor (100), then the decimal point will move 2 place to the left of the last digit.
  • If you have three zeros in the divisor (1000), then the decimal point will move 3 place to the left of the last digit.

$212960\div1000=\frac{212960}{1000}

Here, we have 3 zeros in the denominator.

So, the decimal point is move 3 digit to the left of the last digit.

$212960\div1000=212.96

So, option C is the right answer.

Hence the quotient is 212.96.

Find the linear approximation of the function f(x, y, z) = x2 + y2 + z2 at (6, 6, 3) and use it to approximate the number 6.022
Licemer1 [7]
Near the point (6, 6, 3), we have the approximation

f(x,y,z)\approx f(6,6,3)+f_x(6,6,3)(x-6)+f_y(6,6,3)(y-6)+f_z(6,6,3)(z-3)

where the subscripted f's refer to the corresponding partial derivatives.

f(x,y,z)=x^2+y^2+z^2
\implies\begin{cases}f_x(x,y,z)=2x\\f_y(x,y,z)=2y\\f_z(x,y,z)=2z\end{cases}

So

f(6.02,5.97,2.99)\approx80.8288

Compare to more precise value,

f(6.02,5.97,2.99)\approx80.8214
