If f(x)= 2(3x²-2x+2). Find: A) f(x+1) B) f(3) C) f(y-2)

ExtremeBDS [4]

A) f(x+1) = 6x^2 + 8x + 6
1) substitute the value of x as (x+1)
2) 2(3(x+1)^2 -2(x+1) +2)
3) 6(x^2 + 2x + 1)
4) 6x^2 + 8x + 6

B) f(3) = 46
1) simplify the expression first
2) 6x^2 -4x + 4
3) Now just substitute 3: 6(3)^2 -4(3) + 4
4) 6•9 - 12 + 4 = 46

I hope this helps :)

Your friend is about to begin an introductory chemistry course at his university. The course has collected data from students on

Minchanka [31]

Answer:

The percentage of students sudy 34 hours or more is 0.62%

Step-by-step explanation:

The Normal Distribution

The bell curve or normal distribution is frequently used to model the probability of natural random events. The normal distribution $N(\mu,\sigma)$ is characterized by two parameters:

$\mu$ is the mean value

$\sigma$ is the standard deviation

The study times in hours for the final exam is modeled as a normal distribution N(24,4). We are required to find the percentage of students study 34 hours or more, or P(X>34).

The values for the cumulative probability are given by tables or digital means like Excel where we can get the left-tail or P(X<Xo). To compute the right-tail or P(X>Xo) we use this relation

$P(X>Xo) =1-P(X$

The Excel formula to find the left-tail cumulative probability is called

NORM.DIST(x,mean,standard_dev,cumulative)

To solve the question, we used:

NORM.DIST(34,24,4,TRUE)=0.9938

Thus:

$P(X>34) =1-P(X$

The percentage of students study 34 hours or more is 0.62%

Create and solve a linear equation that represents the model, where squares and triangles are shown evenly balanced on a balance

Rina8888 [55]

Let the weight of triangle be x units. You are given that the weight of square is 1 unit.

1) On the left side of the balanced beam you can see 3 triangles and 5 squares. The weight on left side is 3·x+5·1=3x+5 units.

2) On the right side of the balanced beam you can see 2 triangles and 7 squares. The weight on right side is 2·x+7·1=2x+7 units.

3) If the whole system is balanced, then the weights on left and right sides are equal:

3x+5=2x+7.

Solve this equation:

3x-2x=7-5,

x=2 units.
