Explanation: Ok so what you want to do is find the pretty points first! After you do that make sure you mark it! You want to use Rise/Run when you do this go to the pretty point and go over till you find the next pretty point! So what I see here is that it goes over 2 then down one! So the rate of change should be 2 since 2/1 is 2!

The radius of a circle is decreasing at a rate of 6.56.56, point, 5 meters per minute. At a certain instant, the radius is 12121

Ilia_Sergeevich [38]

Answer:

The rate of change of the area of the circle is approximately $-490.09 \ m^2/min$ .

Step-by-step explanation:

Given:

$\frac{dr}{dt} = -6.5 \ m/min$

radius $r =12 \ m$

We need to find the rate of change of the area of the circle at that instant.

Solution:

Now we know that;

Area of the circle is given by π times square of the radius.

framing in equation form we get;

$A= \pi r^2$

to find the rate of change of the area of the circle at that instant we need to take the derivative on both side.

$\frac{dA}{dt}=\frac{d(\pi r^2)}{dt}\\\\\frac{dA}{dt}= 2\pi r \frac{dr}{dt}$

Substituting the given values we get;

$\frac{dA}{dt}= 2\times \pi \times 12 \times -6.5\\\\\frac{dA}{dt}\approx -490.09 \ m^2/min$

Hence The rate of change of the area of the circle is approximately $-490.09 \ m^2/min$ .

Whats the improper fraction equivalent to 5 5/9

jeka57 [31]

The answer is 50/9.

Explanation:

To convert mixed numbers to improper fractions, I remember MAD (multiply, add, denominator).

Step 1 (M): Multiply the denominator (9) by the whole number (5). You should get 45.

Step 2 (A): Add the numerator (5) to the number you just got (45). 45 + 5 = 50.

Step 3 (D): Take the number you have (50) and put it over the denominator (9). Your final answer is 50/9.
