What is the rate of change of g(x)=x^3-9x for x=1 to x=6

VladimirAG [237]

Answer:

105

Step-by-step explanation:

$g(x)=x^{3}-9x$

rate of change of g(x) is

$g^{,}(x)=3x^{2} -9$

for x=1

$g^{'}(1)=3(1)^{2} -9=-6$

for x=6

$g^{'}(6)=3(6)^{2} -9=99$

For a right triangle, there are relationships between the sides and the angles of the triangle:

$sin\theta=\frac{opposite}{hypotenuse}$

$cos\theta=\frac{adjacent}{hypotenuse}$

$tan\theta=\frac{opposite}{adjacent}$

I would study the attached image for a better understanding.

There are 8 red marbles, 5 blue marbles, 11 green marbles, 1 yellow marble in a jar. Suppose one marble is selected at random. P

dmitriy555 [2]

Given:

Number of red marbles = 8

Number of blue marbles = 5

Number of green marbles = 11

Number of yellow marbles = 1

One marble is selected at random.

To find:

The P(red, green or yellow).

Solution:

Number of red, green or yellow marbles = 8 + 11 + 1

= 20

Total number of marbles = 8 + 5 + 11 + 1

= 25

The probability of getting a red, green or yellow marble is:

$P(\text{red, green or yellow})=\dfrac{\text{number of red, green or yellow marbles}}{\text{Total number of marbles}}$

$P(\text{red, green or yellow})=\dfrac{20}{25}$

$P(\text{red, green or yellow})=\dfrac{4}{5}$

$P(\text{red, green or yellow})=0.8$

Therefore, the value of P(red, green or yellow) is 0.8.
