Answer:
Option E
Step-by-step explanation:
The standard equation of circle is:- (x-h)² + (y-k)² = r²
where (h,k) is center point and r is radius
If radius r is decreased then also (h,k) remains same, only r² increases
Equation given in question is x² + y² + Cx + Dx + E=0
So, C and D will remain same but E will increase
Answer:
Angle T= 36 degrees
Angle V= 54 degress
Step-by-step explanation:
okay so you know that this is a right angle and that all angles in a triangle add up to 180 degress
using that info,
you can say
2x+3x+90= 180
5x+90=180
5x= 180-90
5x= 90
x= 18
measure of angle T= 2x
2(18)= 36 degrees
measure of angle V= 3x
3(18)= 54 degrees

9x3 matrix has 9 rows and 3 columns, so it has 27 elements
By graphing the polynomial, we conclude that there is only one real root, so the correct option is A.
<h3>
How many roots has the given polynomial?</h3>
We have the polynomial:
To see how many real roots this polynomial has, we can graph it and see how many times the graph intercepts the x-axis.
The graph can be seen below:
There we can see that there is only one intercept, so there is only one real root.
So the correct option is A.
