Answer:
Step-by-step explanation:
1.

2.
cosθ+sinθ tan θ
=cosθ+sin θ×(sinθ)/(cosθ)

3.
x²+(y-6)²=35
x²+y²-12y+36=35
x²+y²-12y+1=0
put x=r cosθ
y=r sin θ
square and add
x²+y²=r²cos²θ +r² sin²θ=r² (cos² θ+sin² θ)=r²
r²-12rsinθ+1=0
P is True (x+x does indeed = 2x)
q is False ((3x)(-2y)=-6xy)
pVq is True (TvF is True)
p->q is False (p->q) equiv ~(p^~q) equiv ~(T^~F) equiv ~(T^T) = F
p^~q is True ((T^~F) = T^T = T)
p->~q is True (T->~F)
Answer:
5/8.
Step-by-step explanation:
a^-1 = 1/a
So here we have:
(8/5)^-1
= 1/ (8/5)= 5/8.
Answer:
59
Step-by-step explanation:
1) so you start with the mean being 72x5=360
2)100+42+87+66=295
3) 360-295=65
(you get the 5 from the amount of numbers there are) P.S sorry if I'm wrong or this doesn't help
