Answer:

a) $y=\frac{50}{x}$

b) $y=25$ when $x=2$

Step-by-step explanation:

$y=\frac{k}{x}$ since y varies inversely with x.

We need to find the constant, k.

Let's use a point (x,y) on the curve.

We are given an (x,y)=(5,10):

$10=\frac{k}{5}$

Multiply both sides by 5:

$10(5)=k$

$50=k$ .

So the equation is:

$y=\frac{50}{x}$

What is y when x=2?

$y=\frac{50}{2}$

$y=25$

The width of a rectangle is increasing at a rate of 5 inches per second and its length is increasing at the rate of 9 inches per

Marianna [84]

Answer:

The area of rectangle is changing at the rate of 33 square inches per second.

Step-by-step explanation:

We are given the following information:

Let W be the width of the rectangle and L be the length of rectangle.

Rate of change of width = $\frac{dW}{dt} = 5\text{ inches per second}$

Rate of change of length = $\frac{dL}{dt} = 9\text{ inches per second}$

We have to find rate of change of area at W = 2 and L = 3.

Rate of change of area = $\frac{dA}{dt}$

Area of rectangle = Length × Width

$\frac{dA}{dt} = \frac{d(LW)}{dt} = L\frac{dW}{dt} + W\frac{dL}{dt}$

Putting the values, we get

$\frac{dA}{dt} = 3(5) + 2(9) = 33\text{ square inches per second}$

The area of rectangle is changing at the rate of 33 square inches per second.

When you're trying to simplify an expression which requires several operations, the acronym PEMDAS comes in handy, and here's what it means:-

P = parentheses (x+n)
E = exponents $\bold{x^n}$
M = multiplication x•n
D = division x÷n
A = addition x+n
S = subtraction x-n

With the help of the acronym PEMDAS, we can simplify our expression:-

$\bold{3.14\times6^2}$

Squaring 6 (Exponents):-

$\bold{3.14\times36}$

Which results in

$\boxed{\boxed{\sf{113.04}}}\checkmark$
