Answer:
I have got the answer
Step-by-step explanation:
Let the roots of 2x² + 3x - 1 = 0 be a and
To find:
The quadratic equation whose roots are 3a
Solution:
See picture attahed
The rest of explanation is given in your previously asked question see there I have also answered it
PLEASE MARK ME BRAINLIEST IF MY ANSWER IS CORRECT PLEASE
26.6 mi^2
This cannot have an answer since this is a expression not a equation. If it was something like 4x+26=100, there will be a answer. but this cannot have an answer.
228 feet
Since M represents the number of lessons he completes,
sub M=8 into S=26M+20
S=26(8)+20
=228
The instantaneous rate of change of with respect to at the value is 18.
a) Geometrically speaking, the average rate of change of with respect to over the interval by definition of secant line:
(1)
Where:
, - Lower and upper bounds of the interval.
, - Function exaluated at lower and upper bounds of the interval.
If we know that , and , then the average rate of change of with respect to over the interval is:
The average rate of change of with respect to over the interval is 27.
b) The instantaneous rate of change can be determined by the following definition:
(2)
- Change rate.
, - Function evaluated at and .
If we know that and , then the instantaneous rate of change of with respect to is:
