Answer:

4890

Step-by-step explanation:

Recognize the denominator has been multiplied by 100:

0.03 × 100 = 3

To have the same division problem, the numerator must also be multiplied by 100. This is the sort of decimal point adjustment usually carried out for long division: the divisor is made to be an integer, and the decimal point of the dividend is moved the same direction by the same number of places.

$\dfrac{48.9}{0.03}=\dfrac{48.9\cdot 100}{0.03\cdot 100}=\dfrac{4890}{3}$

The missing number is 4890.

____

The quotient is 1630.

koban [17]

Answer:

1526.0 cubic units

Step-by-step explanation:

Rotating rectangle AKLM you will get cylinder with height KA and base radius KL. From the given data

$KA=\sqrt{(6-0)^2+(0-0)^2}=6,\\ \\KL=\sqrt{(0-0)^2+(9-0)^2}=9.$

The volume of the cylinder is

$V_{cylinder}=\pi r^2\cdot H.$

Then

$V_{cylinder}=\pi \cdot 9^2\cdot 6=486\pi \approx 1526.0\ un^3.$

If x² + xy – 3y = 3, then at the point (2, 1), dy/dx

Scilla [17]

Answer:

A

Step-by-step explanation:

We have the equation:

$x^2+xy-3y=3$

Take the derivative of both sides with respect to x:

$\frac{d}{dx}[x^2+xy-3y]=\frac{d}{dx}[3]$

Implicitly differentiate:

$2x+y+x\frac{dy}{dx}-3\frac{dy}{dx}=0$

Solve for dy/dx:

$\frac{dy}{dx}(x-3)=-2x-y\\$

Divide:

$\frac{dy}{dx}=-\frac{2x+y}{x-3}$

To find dy/dx at (2, 1), substitute 2 for x and 1 for y. So:

$\frac{dy}{dx}_{(2, 1)}=-\frac{2(2)+1}{2-3}=-\frac{5}{-1}=5$

Hence, our answer is A.
