Use cubic regression to find a
function that fits the following
points.
(1,-9), (2,-15), (3,-29),(-1,3)

Answers

Answer 1

The cubic regression equation that fits the points (1,-9), (2,-15), (3,-29),(-1,3) is given as follows:

f(x) = -x³ + 2x² - 5x - 5.

How to find the equation of regression using a calculator?

To find the equation, we need to insert the points (x,y) in the calculator.

In this problem, we have that:

The values of x are: 1, 2, 3, -1.The values of y are: -9, -15, -29, 3.

Using the calculator, the equation is given by:

f(x) = -x³ + 2x² - 5x - 5.

Answer:

Step-by-step explanation:

Equilateral triangles are  

always

acute triangles. Yes, because acute is always 60 degrees, and equilateral is basically your average triangle, so its corners have 60 degrees.

Scalene triangles are  

sometimes

acute triangles.      Scalene triangles always dont have that sharp corner..they sometimes do, the sharp turn which is 60 degrees, ACUTE IS ALWAYS 60 DEGREES.

Right triangles are  

never

acute triangles. A right angle cant be a acute, not 60 degrees..

Obtuse triangles are

isosceles triangles.  Isosceles means atleast 2 of the sides look the same, i included how to recognize obtuse, right,etc

The equation for line g can be written as y = x + 5. Parallel to line g is line h, which passes through the point (-6, -4). What is the equation of line h? SHOW WORK PLEASE​

Answers

Answer:

y=x+2

Step-by-step explanation:

we know the slopes have to be equal because the lines are parallel, so the slope is 1, or written as x. plug the point given, (-6,-4), and the slope, 1, into the y=mx+b equation to find the y-intercept. then solve. then put the slope and y-intercept together for the equation of line h.

y=mx+b, m=1, x=-6, y=-4

-4=(1)(-6)+b

-4=-6+b

2=b

y=x+2

Answer:

8 hours and 54 minuter

Step-by-step explanation:

1 hour is equal to 60 minutes

we have 8 hours and 0.9 hours

0.9*60=54 minutes

we have 8 hours and 54 minuter

Answer:

The last one

Step-by-step explanation:

First you need to figure out how many minutes are in 0.1 hours

you can do this by dividing 60 minutes by 10

you get 6

multiply 6 and 9 so that you can find out how many minutes 0.9 hours are

this leaves you with 54 minutes

so your answer is 8 hours and 54 minutes

Find the slope intercept equation of the line

Answers

Answer:

Step-by-step explanation:

slope-intercept formula looks like [y=mx + b]

use two points to find the slope.. or look at the graph carefully to see it there are easy points to count from.... hmmm

yes.. this is very easy to just count.. no math needed  :P

the slope is posive. b/c the graph looks like you are walking up hill.. and it's rise over run is 2/1  .. so the slope is 2

then by looking at the graph I can also see that when x = 0 the line pass exactly thur +1.. sooo that tells me all I need to know for the sloop-intercept formula

y= 2x+1      :)  see?

f(x)=6x+4. Find the inverse of f(x).

Answers

Answer:

c

Step-by-step explanation:

f(x)=6x+4

y=6x+4

x=6y+4

6y=x-4

y=(x-4)/6

f^-1(x)=(x-4)/6

Answer is Option-C

How to find Inverse Function:

1. First, replace f(x) with y. This is done to make the rest of the process easier.

2. Replace every x with a y and replace every y with an x.

3. Solve the equation from Step 2 for y.

(Here), Given

f(x) = 6x + 4

Let's inverse function be y.

y = 6x + 4

First step is to switch the positions of x and y.

Inverse: x = 6y + 4

x - 4 = 6y

=> y = (1/6) * (x - 4)
