Answer:
y = -2x-18
y = 3/2x + 11/4
Step-by-step explanation:
Hello :
<span>the y-intercept of the function f(x) = 2/9x +1/3
when : x = 0
f(0) = 2/9(0)+1/3 = 1/3 </span>
Constant of proportionality is 4
equation: x/y = 4
explanation:
let's take 20 and 5 for example, if you divide 20 by 5, you will 4 of course. that's the proportionality for the first one. if you continue to divide x value by y value you will get 4. for the last two you would divide 28 by 4 and multiply 8 by 4.
Step-by-step explanation:
the volume of a cylinder is as for any other regular 3D object :
ground area ×height
the ground area of a cylinder is a circle, so it is
pi×radius² × height
the radius is always half of the diameter (of the diameter is airways twice the radius).
radius = 6/2 = 3 ft.
the volume is then
pi × 3² × 9 = pi × 9 × 9 = pi × 81 ft³
so, the answer is 81pi ft³.
