Answer:
y=3
Step-by-step explanation:
F(x)=f(-2) so go to -2 on the x axis and then find the y
Answer:
see explanation
Step-by-step explanation:
We require 2 equations with the recurring decimal placed after the decimal point.
let x = 0.7272.... (1) ← multiply both sides by 100
100x = 72.7272... (2)
Subtract (1) from (2) thus eliminating the recurring decimal
99x = 72 ( divide both sides by 99 )
x = 
= 
The volume of a cone with respect to its diameter is:
V=(hπd^2)/12 solving this for d we have:
d=√[(12V)/(hπ)], we are given that V=128π and h=5 so
d=√(1536π)/(5π)
d=√(1536/5)
d=√307.2 cm
d≈17.53 cm (to nearest hundredth)
Direct variation is of the form y=kx, where k is the constant of variation. We are given the point (6,48) so we can solve for k:
48=6k divide both sides by 6
8=k, so the equation is:
y=8x, then when x=2
y=8(2)
y=16
