You wanna simplify the expression first
5(3m+2p+m)
=15m+10p+5m
so B would be correct
(r, theta)= (8, 3/2 pi)
r=(x^2 +y^2)^(1/2)
theta= 3/2 pi
x= r(costheta)
y=r(sintheta)
x=8(cos(3/2 pi))
y=8(sin(3/2 pi))
x=8(0)
y=8(-1)
x=0
y=-8
r=((-8)^2+(0)^2)^(1/2)
r=(64+0)^(1/2)
r=8
rectangular coordinates= (0,-8)
Answer:
x = π/6, 5π/6
Step-by-step explanation:
4 sin² x − 4 sin x + 1 = 0
(2 sin x − 1)² = 0
sin x = ½
x = π/6, 5π/6
Yes I'm supposed to explain this on 20 chaaracters so hopefully this is enough
Answer:
21
Step-by-step explanation:
6(y^2) - 24y -51 = 6 4 - 24y - 51
(6 4) - (24y) - 51 = 24 - -48 - 51
(24 - -48) - 51 = 72 - 51
72 - 51 = 21
