Answer:
4√10xy/32y is the answer. (I think)
=theta/360°×2pi ×r
theta=180-60=120°
r=24÷2=12
120/360 × 2 × 22/7 × 12=
1/3 × 2 × 22/7 × 12=
176/7=
25.14
78 inches if you you know that a foot is 12 inches you can add 12 for every inch then add 6 for the half making it 78 inches.
These are pretty easy once you get the concept.
think of <em>random letter</em> (x) as the term y, so in the case of p(x)=-3+4x, its just asking what is y when x equals all those values.
so p(-2) = -3 + 4(-2), since its asking to plug in -2 for x, which equals -11
p(0) = -3 + 4(0)
= -3
p(5) = -3 + 4(5)
= 17
