Answer:6
Step-by-step explanation:solve the equation, you know that it equals 90 because the angle is 90
so 16x-6=90
+6 both sides
16x=96
divided by 16 both sides to isolate x
x=6
Answer:
2 real roots
Step-by-step explanation:
If the discriminant is >0 then the equation has 2 real roots
If the discriminant is =0 then the equation has 1 real roots
If the discriminant is <0 then the equation has 2 complex roots
since the discriminant is 4, it has 2 real roots
Given:
The given statement is "A circle is dilated by a scale factor of 1.5 to create a new circle. The area of the new circle is 1.5 times the area of the original circle."
To find:
Whether the given statement in true or false.
Solution:
Area of circle is
Where, <em>r</em> is the radius of the circle.
Let be the radius of the original circle. So, the area of the circle is
The circle is dilated by a scale factor of 1.5 to create a new circle. So, the radius of the new circle is:
The area of the new circle is
The area of the new circle is 2.25 times the area of the original circle.
Therefore, the given statement is false.
