Answer:
It is 9x^3.
Step-by-step explanation:
36x^4 and 45x^3.
GCF of 36 and 45 = 9
GCF of x^4 and x^3 = x^3
GCF of 36x^4 and 45x^2 = 9x^3.
When b^2 -4ac >0 you get rational answers. I suppose you could use factoring as well as the quadratic formula.
when b^2 -4ac =0 You get one answer. Okay it is till technically "two" answers but you say BOTH values of x = whatever.
when b^2 -4ac <0 the answers are complex (imaginary) and have the value of "i" somewhere in them. For example the answers might be 2 + 2i that kind of thing
Answer:
The graph is positive and decreasing for all real values of x where x < -1
Step-by-step explanation:
we have
The function is a vertical parabola open up
The roots (x-intercepts) are x=3 and x=-1
The vertex is the point (1,-4 ) is a minimum
using a graphing tool
see the attached figure
we know that
In the interval (-∞,-1) ---> the function is positive and decreasing
In the interval (-1,1) ---> the function is negative and decreasing
In the interval (1,3) ---> the function is negative and increasing
In the interval (3,∞) ---> the function is positive and increasing
therefore
The graph is positive and decreasing for all real values of x where x < -1
Answer:
(0,7.5)
Step-by-step explanation:
Hte measure of the Length is given by the formula
L= R x teta
so L= 3x2=6 radians.cm
