Answers

Answer 1

Answer:

[tex](f\ o\ g)(x) = 3x[/tex]

[tex]-\infty < x < \infty[/tex]

Step-by-step explanation:

See comment for right presentation of question

Given

[tex]f(x) = ln(x^2)[/tex]

[tex]g(x)=\sqrt{e^{3x}}[/tex]

Solving (a): (f o g)(x)

This is calculated as:

[tex](f\ o\ g)(x) = f(g(x))[/tex]

We have:

[tex]f(x) = ln(x^2)[/tex]

[tex]f(g(x)) = \ln((g(x))^2)[/tex]

Substitute: [tex]g(x)=\sqrt{e^{3x}}[/tex]

[tex]f(g(x)) = \ln(\sqrt{e^{3x}})^2[/tex]

Evaluate the square

[tex]f(g(x)) = \ln(e^{3x})[/tex]

Using laws of natural logarithm:

[tex]\ln(e^{ax}) = ax[/tex]

So:

[tex]f(g(x)) = \ln(e^{3x})[/tex]

[tex]f(g(x)) = 3x[/tex]

Hence:

[tex](f\ o\ g)(x) = 3x[/tex]

Solving (b): The domain

We have:

[tex]f(g(x)) = 3x[/tex]

The above function has does not have any undefined points and domain constraints.

Hence, the domain is: [tex]-\infty < x < \infty[/tex]

Which line has the same slope as the lone passing through (-4,-1) and (-1,-7)
1) 6x+3y=5
2)y=-1/2x-7
3)y=-2

Answers

Answer:

1) 6x+3y=5    

Step-by-step explanation:

1) First, find the slope of the line passing through (-4, -1) and (-1, -7). Use the slope formula [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]. Substitute the x and y values of the two points into the formula and solve:

[tex]m = \frac{(-7)-(-1)}{(-1)-(-4)} \\m = \frac{-7+1}{-1+4} \\m = \frac{-6}{3} \\m = -2[/tex]

So, the slope is -2.

2) Now, identify the slopes of the lines in the options. We already know the slope of [tex]y = -\frac{1}{2} x-7[/tex]  is [tex]-\frac{1}{2}[/tex] since it is in slope-intercept form. y = -2 must have a slope of 0 since it's horizontal, and all equations with the format of y = a number are horizontal.

To find the slope of [tex]6x + 3y = 5[/tex], isolate y to put the equations into slope-intercept form ([tex]y = mx + b[/tex] format), and whatever the coefficient of the x-term is will be the slope.

[tex]6x + 3y = 5\\3y = -6x+5\\y = -2x + \frac{5}{3}[/tex].

So, the slope of the first option is -2. It matches the slope we calculated in the first step, so that must be the answer.

So it would be 12/50 but you can make this smaller so you divide by 2 and get 6/25

You have collected data on the average weekly amount of studying time (T) and grades (G) from peers at your university. Changing the measurement from minutes into hours has the following effect on the correlation coefficient:

a. cannot be computed since some students study less than an hour per week
b. does not change the rTG
c. decreases the rTG by dividing the original correlation coefficient by 60
d. results in a higher rTG

Answers

Answer:

b. does not change the rTG

Step-by-step explanation:

If the average weekly amount of studying time and Grade are compared such that a certain correlation Coefficient value is obtained, changing the unit of measurement of any of the variables, will not affect the value of the correlation Coefficient most notably because the value of R, correlation Coefficient is a normalized or standardized value that ranges between - 1 and 1 and hence, resistant to unit changes in the compared variables. Hence, Correlation coeffient for the rate of study and grade obtained will not change even if rate of study is measured in hour.
