Answer:
Step-by-step explanation:
Given that two tangents to a circle intersect at a point B outside the circle
A and C are points of contact.
By theorem on circles we have angle ABC is equal to 1/2 the difference of intercepted arcs.
Angle of minor arc =110 and hence major arc
Difference =
Measure of angle ABC 1/2 of 140 = 70 degrees.

Answer:
C
Step-by-step explanation:
Given
x² - 6x + 9
Consider the factors of the constant term (+ 9) which sum to give the coefficient of the x- term (- 6)
The factors are - 3 and - 3, since
- 3 × - 3 = + 9 and - 3 - 3 = - 6, thus
x² - 6x + 9 = (x - 3)(x - 3) = (x - 3)² → C
Your answe would be a>-2 so just plug that in to the line and that will be your answer which is the second one
Answer:
2 Real Roots
Step-by-step explanation:
The discriminant (D) is found using the formula b^2+4ac for the equation ax^2+bx+c.
If D>0 there are two real roots, D=0 one real root and D<0 no real roots.
D = b^2+4ac
D = 10^2+4(-4)(-8)
D = 100+32*4
D = 100+128
D = 228
since 228>0
There are 2 real roots
