Y=94 (B) because of angle rules
cos0 = √3/2
1 - cos²0 = sin²0
= 1/4 = sin²0
sin in quadrant 4 is negative
sin0 = -1/2
Answer:
100
Step-by-step explanation:
Forumla is
Original price X rate of discount = discount
The original price is $125, the rate of discount is 20%
So in math form, this is 125 x .20
which equals 25.
Lastly, just subtract that from the original price. 125 - 25 = 100.
Answer:
5, ±√6i
Step-by-step explanation:
f(x)=x^3-5x^2+6x-30=x^2(x-5)+6(x-5)=(x^2+6)(x-5)
to make f(x)=0, x^2+6=0 or x-5=0
x^2=-6; x=±√6i
x-5=0; x=5
