Step-by-step explanation:
x^2 - 7x + 4.
The discriminant of the above
= b^2 - 4ac
= (-7)^2 - 4*1*4
= 49 - 16
= 33.
Answer:
Step-by-step explanation:
it's A, C , B
Answer:
sin(71°)
Step-by-step explanation:
Sine lags behind cosine by 90°
In other word, cos(∅) = sin(90° - ∅)
cos(19°) = sin(90° - 19°)
= sin(71°)
Your answer is 400,000.
Hope this helps!
