C. 30°,60°,90° due to the fact that it's a right triangle
Answer:
I believe the answer is C. 90 degrees
Step-by-step explanation:
First you find the lengths of the two vectors, which are both
. Then you find the angle given the cos using: cos(∅)=
=
= 0. Then using ∅=acos(0)=
= 90°
Answer:
4
-16x+8
Step-by-step explanation:
4(x - 2)(x - 2) - 8 = 4(
- 4x + 4) - 8 = 4
- 16x + 16 - 8 = 4
- 16x + 8.
It would be the one with the greater numerator 6/6 would be greater than 5/6
Answer:
positive
Step-by-step explanation:
the discriminant of the function is postive.
because from the graph we notice that it has 2 intercepts on x-axis, which means the function has 2 real solution when y=0
that implies the discriminant is positive.

if
we have 2 distinct real solution
if
we have no real solution but 2 complex solutions
if
we have 2 identical real solution
