Answer:
29) discriminant is positive
30) discriminant is 0
31) discriminant is negative
Step-by-step explanation:
the graph of a quadratic function y=ax^2 + bx + c is shown. Tell whether the discriminant of ax^2 + bx + c = 0 is positive, negative, or zero.
In the graph of question number 29 we can see that the graph intersects the x axis at two points
so the equation has 2 solutions.
When the equation has two solution then the discriminant is positive
In the graph of question number 30 we can see that the graph intersects the x axis at only one point
so the equation has only 1 solution.
When the equation has only one solution then the discriminant is equal to 0
In the graph of question number 30 we can see that the graph does not intersects the x axis
so the equation has 2 imaginary solutions.
When the equation has two imaginary solutions then the discriminant is negative
Hello :)
196 = 14.14 so the answer is D
169 = 13.13
144=12.12

Have a nice day :)
V=bh/3
V=(2*32)/3
V=64/3
V=21.3333 ( Round answer as needed)
Answer:
(a) 
Multiplicative inverse of w will be 
(B) As w is same as the product of 
So there multiplicative inverse will also be same
Step-by-step explanation:
We have given two complex numbers
and 
(a) First we have to find 
So 
As we know that 
So
Multiplicative inverse :
It is that number when multiply with the number which we have have to find the multiplicative inverse gives result as 1
So multiplicative inverse of w will be
Because when we multiply 
with it gives result as 1
(b) As w is same as the product of
So there multiplicative inverse will also be same
