Given the function g(x) = x2 + 5x + 1, determine the average rate of change of

Elden [556K]

Answer:

-6

Step-by-step explanation:

The average rate of change of a function, f(x), on interval [a,b] is (f(b)-f(a))/(b-a).

So the avereage rate of change of a function, f(x)=x^2+5x+1, on [-9,-2] is

(f(-2)-f(-9))/(-2--9)

(f(-2)-f(-9))/(7)

Stop!

To find f(-2), you replace x in f(x) = x^2 + 5x + 1, with (-2) giving you f(-2)=(-2)^2+5(-2)+1=4-10+1=-6+1=-5.

To find f(-9), you replace x in f(x) = x^2 + 5x + 1, with (-9) giving you f(-2)=(-9)^2+5(-9)+1=81-45+1=36+1=37.

Continue!

(f(-2)-f(-9))/(7)

=(-5-37)/7

=(-42)/7

=-42/7

=-6

Cual es la simplificacion de 66/81

Karo-lina-s [1.5K]

Answer:

Hence the simplification of $\dfrac{66}{81}$ is $\dfrac{22}{27}$

Step-by-step explanation:

" Simplification is the process of replacing a mathematical expression by an equivalent one, that is simpler (usually shorter),

for example: Simplification of a fraction to an irreducible fraction ".

Here we are given a fraction as:

$\dfrac{66}{81}$

As both the numerator and denominator are divisible by a factor of 3 hence we take out the common factor and obtain the reduced fraction which is further irreducible.

As 66=3×22 and 81=3×27

Hence $\dfrac{66}{81}=\dfrac{3\times22}{3\times27}=\dfrac{22}{27}$

Hence the simplification of $\dfrac{66}{81}$ is $\dfrac{22}{27}$

What is the volume of a cylinder with a radius of 3 feet and a height of 4 feet? Use 3.14 for pi. Enter your answer in the box.

natta225 [31]

volume of a cylinder = V = πr²h, r = radius and h = height.

if r = 3 and h = 4, then V = π3²(4) => V = 36π => V ≈ 113.1.
