Answer:

A = πr²

Step-by-step explanation:

The formula for the area of a circle is A = πr², where π is approx. 3.14159 and r is the radius of the circle.

π is 3.14. <em>r</em> is the radius of the circle.

If r = 3 then the area is 28.27.

π × 3² | Replace <em>r </em>with your circle's radius
3.14... × 9 | Solve groups
3.14... × 9 ≈ 28.27

Consider the function f ( x ) = 1 − 4 x 2 on the interval [ − 1 , 3 ] . Find the average or mean slope of the function on this i

Blababa [14]

Answer:

The average slope is 8.

Step-by-step explanation:

Let <em>f</em> be defined on the closed interval [a, b]. The average slope of <em>f </em>between a and b is the quotient

average slope = $\frac{f(b)-f(a)}{b-a}$

To find the average slope of the function $f(x)=1-4x^2$ on the interval [-1, 3] you have to evaluate your function in the interval and then divide by the interval.

So,

$f(-1)=1-4(-1)^2=-3\\\\f(3)=1-4(3)^2=-35$

The average slope is $\frac{f(3)-f(-1)}{3+1}= \frac{-3+35}{3+1}=\frac{32}{4}=8$
