Answer:
1/3
Step-by-step explanation:
The equation given to you is in y=mx+b form.
m is the slope which in this case would be 2/9.
b is the y-intercept which in this case would be 1/3
Answer:
46.4 & 11.6
Step-by-step explanation:
I just did some guess and check, but 46.4/11.6 = 4 and 46.4+11.6 = 58
Answer:
-4i = 4(cos 270 +i sin 270)
Step-by-step explanation:
We have a+ib = r(cosθ+isinθ)

Here a = 0 and b = -4
Substituting

-4i = 4(cos 270 +i sin 270)
Answer:
V(cylinder) = πr²h
h=3 cm
r=2 cm
V(cylinder) = πr²h = π*2²*3 =12π cm³
Answer : 12π cm³.
