Answer:
y = - 9.1768x2 + 122.2567x + 14.9091
Step-by-step explanation:
Given the following :
Month (x) Daily Rental Price (y) 1 $154 2 $205 3 $266 4 $358 5 $403 6 $425 7 $437 8 $430 9 $381 10 $285 11 $211 12 $195
Using the online regression equation graphing tool ; The quadratic model obtained in the form,
y = Ax^2 + Bx + C is :
y = - 9.1768x2 + 122.2567x + 14.9091
Attached below is a picture of the quadratic regression curve.
Answer:
3.940201X 10^115
Step-by-step explanation:
2^3x (2x2x2x2x2x2x2)
2^3x128
2^384
3.940201 x 10^115
Answer:
4 hours and 30 minutes
Step-by-step explanation:
I'll assume you have a basic knowledge of time and know the sequence. So all you do is count to 1:00 and see how many steps you took. In this case 4, but then you have 30 minutes left. Add that to the 4 hours, and you have a total of 4 hours and 30 minutes of elapsed time.
Hope this helps :)
Mult. the 2nd eqn by 6 and then add this "new" equation to the 1st given eqn:
-6x + y = -2
6x -18y = 54
--------------------
-17y = 52, or y = -52/17. Subst. this value of y into either equation to find the value of x.
Answer:
-7 degrees
Step-by-step explanation:
The temperature is predicted to be ...
5 +3(-4) = 5 -12 = -7 . . . . degrees
__
To find the change, multiply the rate of change by the time period. To find the new temperature, add the change to the starting temperature.
